[0002] Portable electronic devices can be used in a variety of environments. For example, users of portable electronic devices can use them in various public places such as department stores, buses, or subways. When an electronic device is used in such a public place, such as in a subway where the user is close to others, the screen of the user's electronic device may be recognized by a third party, regardless of the user's intention. Summary of the Invention

[0003] Technical issues

[0004] As mentioned above, the usage environment of conventional electronic devices poses a risk of exposing users' undisclosed information to third parties. To prevent this, a method has been proposed to attach a polarizer film to the front surface of the display of an electronic device. However, this requires a separate cost for attaching the polarizer film, and in certain types of electronic devices, such as foldable electronic devices, the folding operation may be problematic when the polarizer film is attached.

[0042] In the following description, various embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0043] Figure 1 This is a view illustrating an example configuration of an electronic device according to an embodiment of the present disclosure.

[0044] Reference Figure 1 The electronic device 100 (or display device) may include a communication circuit 110, an input unit 120, a memory 140, a display 160 (or display panel), and a processor 150. In the following description, the display 160 may include a plurality of pixels, each of which may include red, green, blue (RGB), or RGGB sub-pixels. The plurality of pixels may be used to provide various display driving schemes (e.g., a scheme that selectively drives at least one of a first type of sub-pixel having light irradiance characteristics of a first viewing angle and a second type of sub-pixel having light irradiance characteristics of a second viewing angle). For example, the plurality of pixels may support normal mode operation of the screen while simultaneously configuring the first type of sub-pixels and the second type of sub-pixels to operate together, and privacy mode (or narrow viewing angle) operation of the screen by using only the second type of sub-pixels. The second type of sub-pixels may include micropixels driven by a single electrode (e.g., micropixels of the same color). As mentioned above, a subpixel can mean a light-emitting mechanism or light-emitting component that irradiates colors such as R, G, and B, and at least some of the light-emitting mechanisms and light-emitting components can include a subpixel structure having multiple configurations (e.g., at least including anode electrode, cathode electrode, organic light-emitting layer, and semiconductor layer). Therefore, the meaning of a subpixel can at least include the meaning of a subpixel structure.

[0045] The communication circuit 110 can support the communication functions of the electronic device 100. For example, the communication circuit 110 can support at least one of long-range or short-range communication based on the base station of the electronic device 100. In this regard, the communication circuit 110 may include multiple communication modules (or circuits) (e.g., mobile communication modules using mobile communication networks (such as third-generation (3G), fourth-generation (4G), and fifth-generation (5G) networks) and short-range communication modules supporting short-range communication channels (such as Bluetooth or Wi-Fi). According to an embodiment, the communication circuit 110 can form a communication channel with the server under the control of the processor 150 and can receive web pages or information provided by the server. Depending on the type of communication channel formed based on the communication circuit 110 (e.g., short-range or long-range communication channel), the driving scheme of the display 160 (e.g., privacy mode or normal mode) may be different. Furthermore, the driving scheme of the display 160 can be changed according to the type of server accessed through the communication circuit 110 or the type of information received through the communication circuit 110.

[0046] Input unit 120 can support the input function of electronic device 100. For example, input unit 120 may include at least one of the following: at least one physical button, electronic pen, microphone for receiving user input voice, touch mechanism, or sensor. When display 160 includes touch input function, display 160 may be included in the configuration of input unit 120. Input unit 120 can generate setting input signals related to the scheme driving display 160 according to user control, and can transmit such signals to processor 150. In addition, input unit 120 can generate input signals requesting the execution of at least one application installed in electronic device 100 according to user control, and can transmit such signals to processor 150.

[0047] Memory 140 may store at least one of data, programs, or applications related to the operation of electronic device 100. Memory 140 may store setting information 141 related to a scheme for driving display 160. Setting information 141 may include information for selecting a scheme for driving display 160 based on the operating environment of electronic device 100 (e.g., the type of application being executed or the operating state of communication circuit 110). Setting information 141 may include an application list 143. Application list 143 may include at least one application and information for determining a scheme for driving display 160 when the at least one application is executed. A scheme for driving display may include a first driving scheme or a second driving scheme. A first driving scheme may include a scheme that enables all first type sub-pixels 161 (or first pixel group or first type pixel set) and second type sub-pixels 162 (or second pixel group or second type pixel set) of display 160 for driving. A second driving scheme may include a scheme that disables the first type sub-pixels 161 and enables the second type sub-pixels 162 for driving.

[0048] Display 160 may include at least one screen related to the operation of electronic device 100. Display 160 may output a screen displaying setting information 141 related to a driving scheme or a screen display related to changes in the setting information 141. For example, display 160 may output an application list 143 display screen, an application list 143 display screen according to a driving scheme, an application addition or deletion screen, or a screen display that changes according to an application's driving scheme. When display 160 operates according to a first driving scheme, the screen display output by display 160 can be observed within a first viewing angle. When display 160 operates according to a second driving scheme, the screen display output by display 160 can be observed within a second viewing angle smaller than the first viewing angle. In this regard, display 160 may include a first type of sub-pixel 161 and a second type of sub-pixel 162. The first type of sub-pixel 161 may irradiate light so that the screen display can be observed within the first viewing angle. The second type of sub-pixel 162 may irradiate light so that the screen display can be observed within a second viewing angle smaller than the first viewing angle.

[0049] Processor 150 can perform data transmission and signal processing related to the operation of electronic device 100. Processor 150 can determine the driving scheme for display 160 based on the type of communication channel formed via communication circuit 110. For example, when display 160 is driven via a base station-based communication channel, processor 150 can drive display 160 according to a first driving scheme; when display 160 is driven via a short-range communication channel, processor 150 can drive display 160 according to a second driving scheme. Processor 150 can determine the driving scheme for display 160 based on the type of server accessed via communication circuit 110. For example, when the accessed server is a portal website, processor 150 can drive display 160 according to a first driving scheme; when the accessed server is a financial or stock website, processor 150 can drive display 160 according to a second driving scheme. Processor 150 can determine the driving scheme for display 160 based on the type of information received via communication circuit 110. For example, when the information received through the communication circuit 110 is a normal message or information, the processor 150 can drive the display 160 according to the first driving scheme. When the information received through the communication circuit 110 is security information (or the information transmission / reception channel of the communication circuit 110 is a security channel), the processor 150 can drive the display 160 according to the second driving scheme.

[0050] The processor 150 can determine the driving scheme for the display 160 based on the type of application being executed. For example, when a screen output is requested based on a web application, the processor 150 can drive the display 160 according to a first driving scheme, and when a screen output is requested based on a gallery, email, or messenger application, the processor 150 can drive the display 160 according to a second driving scheme.

[0051] The processor 150 can change the driving scheme of the display 160 according to user input or settings changes. For example, when it receives user input for changing the driving scheme of the display 160 from the input unit 120, the display 160 with input function, or the microphone, it can change the driving scheme of the display 160 according to the corresponding input.

[0052] The processor 150 can change the driving scheme of the display 160 based on information from the sensors. In this regard, the electronic device 100 may further include sensors (e.g., an illuminance sensor). For example, when the external light intensity is a specific value or greater (e.g., in an outdoor environment), the processor 150 can drive the display 160 according to a first driving scheme, and when the external light intensity is less than a specific value (e.g., in an indoor environment), the processor 150 can drive the display 160 according to a second driving scheme. As another example, the sensor may include at least one of a fingerprint sensor, iris sensor, gesture sensor, gyroscope sensor, atmospheric sensor, magnetic sensor, accelerometer, grip sensor, proximity sensor, color sensor, infrared (IR) sensor, biometric sensor, temperature sensor, or humidity sensor, and the processor 150 can drive the display 160 according to the first or second driving scheme based on sensor information collected by the sensor.

[0053] In operation under a second driving scheme (e.g., narrow viewing angle mode), processor 150 may execute control to turn off the first type subpixel 161 or display a color with a specific grayscale value (e.g., black with a specific value or smaller (e.g., 10 or smaller)). As the brightness of display 160 is adjusted, processor 150 may adjust at least one of the values ​​of the specific grayscale values ​​or colors of the first type subpixel 161. For example, when a brightness adjustment-related event occurs based on user input or operation of a specific application, processor 150 may adjust at least one of the values ​​of the specific grayscale values ​​or colors of the first type subpixel 161 according to that event. When processor 150 operates under the second driving scheme (e.g., narrow viewing angle mode), the contrast of the first type subpixel 161 may be operated to be lower than the contrast of the first type subpixel 161 in normal mode.

[0054] Figure 2aThis is a view illustrating an example of some pixel structures of a display device according to an embodiment of the present disclosure. Figure 2b This is a view illustrating another example of the pixel structure of a display device according to an embodiment of the present disclosure.

[0055] Reference Figure 2a and Figure 2b In the display 160, the first type of sub-pixel 161 and the second type of sub-pixel 162 can be alternately set. Figure 2a and Figure 2b In the illustrated embodiment, the first type sub-pixel 161 and the second type sub-pixel 162 are alternately arranged, but this disclosure is not limited thereto. For example, the arrangement ratio of the first type sub-pixel 161 and the second type sub-pixel 162 can be changed. For example, the structure for setting the pixels of the display 160 may include a structure in which one first type sub-pixel 161 is set while two second type sub-pixels 162 are set, or vice versa.

[0056] The display 160 may include first type pixels 160a and second type pixels 160b. Each first type pixel 160a may include first type sub-pixels 161R, 161B, 161Ga, and 161Gb, wherein at least two have different sizes. For example, the light-emitting area of ​​the first type blue sub-pixel 161B may be larger than the light-emitting area of ​​the first type red sub-pixel 161R, and the light-emitting area of ​​the first type red sub-pixel 161R may be larger than the light-emitting areas of the first type green sub-pixels 161Ga and 161Gb. According to embodiments of this disclosure, the first type green sub-pixels 161Ga and 161Gb may have the same size.

[0057] Reference Figure 2aA first shielding member 161BM (e.g., a black matrix (BM)) may be disposed between the perimeter of the first type pixel 160a and the first type sub-pixels 161R, 161B, 161Ga, and 161Gb. The first shielding member 161BM may have a specific thickness and width, and may be disposed on the first type sub-pixels 161R, 161B, 161Ga, and 161Gb. Regarding a direction perpendicular to the front surface of the display 160, the first shielding member 161BM may be disposed at a position spaced apart from the perimeter of the first type sub-pixels 161R, 161B, 161Ga, and 161Gb. The opening formed by the shielding members 161BM, 162BM, and 162BMA of the first type pixel 160a and the second type pixel 160b may be filled with a color filter for a specific color. In a pixel structure formed by shielding members of first type sub-pixels and second type sub-pixels (or micropixels) and filling the opening of the color filter, there is no polarizing plate (polarizing film) between the encapsulation layer (e.g., TFE) and the window (e.g., light-transmitting protective layer) of the display 160, and the shielding members can prevent visual recognition of areas other than pixels due to external light.

[0058] Reference Figure 2b The modified first-type pixel 160c may include a first shielding member 161BM disposed at the pixel perimeter. The modified first-type pixel 160c may include a structure in which no separate shielding member is disposed at the pixel perimeter. Therefore, in the modified first-type pixel 160c, no first shielding member 161BM may be disposed between the first-type sub-pixels 161R, 161B, 161Ga, and 161Gb. The modified first-type pixel 160c may have a structure in which a second shielding member 162BM disposed with respect to the second-type pixel 160b is configured to surround the perimeter of the pixel and be surrounded by the second-type pixel 160b. Therefore, the first shielding member 161BM of the modified first-type pixel 160c may be substantially at least a portion of the second shielding member 162BM of the second-type pixel 160b, or may be configured identically to the second shielding member.

[0059] Each second-type pixel 160b may include second-type sub-pixels 162R, 162B, 162Ga, and 162Gb, wherein at least two have different sizes. Among the second-type sub-pixels 162R, 162B, 162Ga, and 162Gb, the second-type blue sub-pixel 162B may include a first blue micropixel 162B1, a second blue micropixel 162B2, a third blue micropixel 162B4, and a fourth blue micropixel 162B4. The second-type red sub-pixel 162R may include a first red micropixel 162R1, a second red micropixel 162R2, a third red micropixel 162R3, and a fourth red micropixel 162R4. The second-type green sub-pixels 162Ga and 162Gb may include a first green micropixel 162G1, a second green micropixel 162G2, a third green micropixel 162G3, and a fourth green micropixel 162G4. According to embodiments of this disclosure, the second type of green sub-pixels 162Ga and 162Gb can have the same size.

[0060] A second shielding member 162BM (e.g., a black matrix (BM)) may be disposed between the perimeter of the second type pixel 160b and the perimeters of the second type sub-pixels 162R, 162B, 162Ga, and 162Gb, and a third shielding member 162BMA may be configured to divide the areas of the second type sub-pixels 162R, 162B, 162Ga, and 162Gb. The second shielding member 162BM may have a specific thickness and width, and may be disposed around the second type sub-pixels 162R, 162B, 162Ga, and 162Gb. Regarding a direction perpendicular to the front surface of the display 160, the second shielding member 162BM may be disposed at a position spaced apart from the perimeters of the second type sub-pixels 162R, 162B, 162Ga, and 162Gb. The third shielding member 162BMA may have the same or similar thickness and width as the second shielding member 162BM. Furthermore, the third shielding member 162BMA may have a width smaller than that of the second shielding member 162BM. According to an embodiment, the second shielding member 162BM can shield light input from the outside. The second shielding member 162BM and the third shielding member 162BMA can be formed of the same material. The second shielding member 162BM and the third shielding member 162BMA can be disposed on the same layer or can be integrally formed.

[0061] The opening regions (e.g., regions opened by a shielding member) of the first blue micropixel 162B1, the first red micropixel 162R1, and the first green micropixel 162G1 can be the same or similar in size. Under this condition, the light-emitting area of ​​the first blue micropixel 162B1 can be larger than the light-emitting area of ​​the first red micropixel 162R1, and the light-emitting area of ​​the first red micropixel 162R1 can be larger than the light-emitting area of ​​the green micropixel 162G1.

[0062] Figure 2a A display with a pentile structure in which four sub-pixels constitute one pixel is shown, but this disclosure is not limited thereto. The arrangement structure of the first type pixel 160a and the second type pixel 160b according to embodiments of this disclosure can also be applied to the strip structure display 160. The second type sub-pixels 162R, 162B, 162Ga and 162Gb may include different numbers of micropixels. For example, each of the second type blue sub-pixel 162B and the second type red sub-pixel 162R may include four micropixels, and each of the second type green sub-pixels 162Ga and 162Gb may include two micropixels, but this disclosure is not limited thereto.

[0063] Figure 2c This is a view illustrating another example of the pixel structure of a display device according to an embodiment of the present disclosure.

[0064] Reference Figure 2c In the display 160, the modified first type pixel 160c and third type pixel 160d can be set alternately. Figure 2c The illustrated embodiment shows a structure in which first-type pixels 160c and third-type pixels 160d are alternately arranged, but this disclosure is not limited thereto. For example, the arrangement ratio of first-type pixels 160c and third-type pixels 160d can be changed. The structure for setting pixels of display 160 according to embodiments of this disclosure may include a structure in which one first-type pixel 160c is set while two third-type pixels 160d are set simultaneously, or vice versa. In display 160, the above has already been... Figure 2a and Figure 2b Pixels of the types described herein can be configured together. For example, at least a portion of the display 160 may include a structure in which first type pixels 160c, second type pixels 160b (or 160c), and third type pixels 160d are alternately arranged.

[0065] Each modified first-type pixel 160c may include first-type sub-pixels 161R, 161B, 161Ga, and 161Gb, wherein at least two have different sizes. For example, the light-emitting area of ​​the first-type blue sub-pixel 161B may be larger than the light-emitting area of ​​the first-type red sub-pixel 161R, and the light-emitting area of ​​the first-type red sub-pixel 161R may be larger than the light-emitting areas of the first-type green sub-pixels 161Ga and 161Gb. According to embodiments of this disclosure, the first-type green pixels 161Ga and 161Gb may have the same size.

[0066] According to embodiments of this disclosure, a separate shielding member may not be required between the perimeter of the modified first-type pixel 160c and the first-type sub-pixels 161R, 161B, 161Ga, and 161Gb. According to another embodiment of this disclosure, a separate shielding member may not be required only between the first-type sub-pixels 161R, 161B, 161Ga, and 161Gb; the shielding member may be disposed at the perimeter of the modified first-type pixel 160c. Because a modified first-type pixel 160c is configured to be surrounded by four third-type pixels 160d, at least two shielding members disposed in the third-type pixels 160d may be disposed at the perimeter of the first-type pixel 160c. The opening formed by the shielding members 163BM and 163BMA of the third-type pixel 160d may be filled with a color filter for a specific color. In a pixel structure formed by shielding members of third-type sub-pixels 163B, 163R, 163Ga, 163Gb (or intermediate-type micropixels) and filling the openings of color filters, there is no polarizing plate (polarizing film) between the encapsulation layer (e.g., TFE) and the window (e.g., light-transmitting protective layer) of the display 160, and the shielding members can prevent visual recognition of areas other than pixels due to external light.

[0067] Each third-type pixel 160d may include third-type sub-pixels 163R, 163B, 163Ga, and 163Gb, at least some of which have different sizes. Third-type green pixels 163Ga and 163Gb may have the same size. Third-type blue sub-pixels 163B may include a fifth blue micropixel 163B1 and a sixth blue micropixel 163B2. The sum of the sizes of the fifth blue micropixel 163B1 and the sixth blue micropixel 163B2 may be the same as, or larger than, the size of the blue sub-pixel 161B of the modified first-type pixel 160c. Third-type red sub-pixels 163R may include a fifth red micropixel 163R1 and a sixth red micropixel 163R2. The sum of the sizes of the fifth red micropixel 163R1 and the sixth red micropixel 163R2 may be the same as, or larger than, the size of the red sub-pixel 161R of the first-type pixel 160c. Third-type pixel 160d may include green sub-pixels 162Ga and 162Gb. The size of the green subpixel can be the same as the size of the green subpixel included in the modified first type pixel 160c.

[0068] Shielding members 163BM and 163BMA (e.g., a black matrix (BM)) may be disposed between the perimeter of the third type pixel 160d and the perimeter of the third type sub-pixels 163R, 163B, 163Ga, and 163Gb. The size of the opening formed by the shielding members 163BM and 163BMA (e.g., an opening filled with insulating material and through which light can pass) may be larger than the sizes of micropixels 163R1, 163R2, 163B1, and 163B2, and the sizes of the green sub-pixels 163Ga and 163Gb. The size of the first red micropixel 162R1 of the aforementioned second type pixel 160b may be the same as or larger than half the size of the fifth red micropixel 163R1 described in the third type pixel 160d. Similarly, the size of the first blue micropixel 162B2 of the second type pixel 160b may be the same as or larger than half the size of the fifth blue micropixel 163B1 described in the third type pixel 160d. As described above, in the display 160 including the third type of pixels 160d, because of... Figure 2a and Figure 2b Compared to the micropixels described herein, relatively large micropixels can be applied, making their design easier and improving the lifespan performance of OLEDs. Furthermore, when the third type of pixel 160d is applied across the entire display 160, relatively superior high resolution can be achieved, and visibility and screen quality (e.g., color deviation) can be improved.

[0069] Figure 3a This is a view illustrating an example of a stacked structure of subpixels of a type according to an embodiment of this disclosure. Figure 3b This is a view showing the luminance characteristics of a first type of sub-pixel and a second type of sub-pixel according to an embodiment of the present disclosure. Figure 3c This is a view illustrating another example of a stacked structure of a second type of subpixels according to an embodiment of the present disclosure.

[0070] Reference Figure 2a and Figure 3a The first type sub-pixel structure 201 corresponding to the first type sub-pixel 161 (e.g., with Figure 2a or Figure 2b The pixel structure corresponding to the first type blue sub-pixel 161B, the first type red sub-pixel 161R, and the first type green sub-pixels 161Ga and 161Gb may include a substrate portion 160_1, a semiconductor layer 160_2, a first electrode 160_3 (e.g., an anode), a pixel defining member 160_4 (e.g., a pixel defining layer (PDL)), an organic light-emitting layer 160_5, a second electrode 160_6 (e.g., a cathode), an encapsulation layer 160_7, a light-transmitting protective layer 160_8, and a second shielding member 162BM. The substrate portion 160_1 may be formed of a deflectable material. For example, the substrate portion 160_1 may be formed of a deflectable material such as polyimide or acrylic. In various embodiments, the substrate portion 160_1 may include at least one of polyethylene terephthalate, polymethyl methacrylate, polyamide, polyimide, polypropylene, or polyurethane. The substrate portion 160_1 may include multiple layers.

[0071] A semiconductor layer 160_2 may be disposed on a substrate portion 160_1. The semiconductor layer 160_2 may be based on low-temperature polycrystalline silicon (LTPS). The semiconductor layer 160_2 may be deposited below a first electrode 160_3. The first electrode 160_3 may be disposed on the semiconductor layer 160_2 and may form an electric field together with a second electrode 160_6 when the semiconductor layer 160_2 is driven. A pixel defining member 160_4 may be configured to surround at least a portion of the perimeter of the first electrode 160_3. An organic light-emitting layer 160_5 may be deposited to at least cover the pixel defining member 160_4 and the first electrode 160_3. A second electrode 160_6 may be deposited on the organic light-emitting layer 160_5. The first electrode 160_3 and the second electrode 160_6 may receive power to form an electric field according to the control of the semiconductor layer 160_2. In this case, the organic material disposed in the organic light-emitting layer 160_5 can irradiate light by emitting light according to the influence of the electric field. The organic light-emitting layer 160_5 can be formed to emit any of the following colors: blue, red, and green.

[0072] The encapsulation layer 160_7 can be configured to cover the upper side of the second electrode 160_6. The encapsulation layer 160_7 can be formed, for example, by thin-film encapsulation. Because of the encapsulation layer 160_7, an air gap may not be present between the light-transmitting protective layer 160_8 and the second electrode 160_6. The display 160 can be a flexible display. The encapsulation layer 160_7 may further include a touch panel or a micro-light control pattern (MLP) structure (or a material with a specific dielectric constant and a specific thickness between the panel and the electrode, or an organic or inorganic film as a light path adjustment film). The encapsulation layer 160_7 can seal the second electrode 160_6 by covering its entire upper surface. The encapsulation layer 160_7 can prevent the introduction of external moisture and oxygen by sealing the second electrode 160_6. The encapsulation layer 160_7 can include multiple layers, and may include three layers, wherein an inorganic film, an organic film, and an inorganic film are sequentially disposed. The light-transmitting protective layer 160_8 disposed on the encapsulation layer 160_7 can be formed of flexible polyimide, acrylic, or bendable thin tempered glass, and can have a specific or greater dielectric constant. The light-transmitting protective layer 160_8 may include at least one of polyimide (PI), polyethylene (PET), polyurethane (PU), cellulose triacetate (TAC), or ultrathin glass (UTG).

[0073] The second shielding member 162BM may be disposed between the encapsulation layer 160_7 and the light-transmitting protective layer 160_8. At least a portion of the second shielding member 162BM may be configured to overlap with the pixel defining member 160_4 in a first direction (z-axis direction) perpendicular to the front surface of the display (or a direction facing the front surface of the display 160 and perpendicular thereto, or a direction from the upper surface of the display 160 to the lower surface of the display 160 and perpendicular thereto). Regarding the first direction (z-axis direction), the second shielding member 162BM may be configured to cover a portion of the perimeter of the pixel defining member 160_4 (e.g., the perimeter in the outward direction relative to the first electrode 160_3). The first type sub-pixel structure 201 may include a first opening 161_1 of a first size 161W1 formed by the second shielding member 162BM. The first opening 161_1 may be at least a portion of the light-transmitting protective layer 160_8. The first opening 161_1 may be filled with a color filter. The first type of subpixel structure 201 may include a region in which no pixel defining member 160_4 is applied, serving as a light irradiation region of a light-emitting member. This light-emitting member includes a light-emitting region 161_2 of second size 161W2 (e.g., a semiconductor layer 160_2), at least a portion of a first electrode 160_3, at least a portion of an organic light-emitting layer 160_5, and at least a portion of a second electrode 160_6. A first opening 161_1 of first size 161W1 may have a larger size than the light-emitting region 161_2 of second size 161W2. Therefore, the first type of subpixel structure 201 can support a normal mode in which the screen of display 160 can be viewed from a first viewing angle.

[0074] The second type sub-pixel structure 202 corresponding to the second type sub-pixel 162 (e.g., with) Figure 2a or Figure 2b The pixel structure corresponding to the second type blue sub-pixel 162B, the second type red sub-pixel 162R, and the second type green sub-pixels 162Ga and 162Gb may include a substrate portion 160_1, a semiconductor layer 160_2, a first electrode 160_3 (e.g., an anode), a pixel defining member 160_4, an additional pixel defining member 160_4A (e.g., a photosensitive material or photoresist), an organic light-emitting layer 160_5, a second electrode 160_6 (e.g., a cathode), an encapsulation layer 160_7, a light-transmitting protective layer 160_8, a second shielding member 162BM, and a third shielding member 162BMA. A second opening 162_1 of the third size 162W1 may be formed between the second shielding member 162BM and the third shielding member 162BMA. The second opening 162_1 may be at least a portion of the light-transmitting protective layer 160_8. The second opening 162_1 may be filled with a color filter.

[0075] The substrate portion 160_1 may have the same configuration as the substrate portion 160_1 described above in the first type sub-pixel structure 201. Furthermore, the semiconductor layer 160_2 may be disposed on the substrate portion 160_1 in a matrix form. A first electrode 160_3 may be disposed on the semiconductor layer 160_2. The first electrode 160_3 may be disposed on the semiconductor layer 160_2 and may form an electric field together with the second electrode 160_6 when the semiconductor layer 160_2 is driven. A pixel defining member 160_4 may be configured to surround at least a portion of the perimeter of the first electrode 160_3. An additional pixel defining member 160_4A may be configured to divide the light-emitting region 162_2 of the fourth dimension 162W2 of the second type sub-pixel structure 202. For example, the additional pixel defining member 160_4A may be configured to span the central portion of the first electrode 160_3. The pixel defining member 160_4 and the additional pixel defining member 160_4A may be formed from the same material using the same process. Since the additional pixel defining member 160_4A is disposed in the first electrode 160_3, the additional defining member 160_4A can prevent the formation of an electric field between the first electrode 160_3 and the second electrode 160_6. The linewidths of the pixel defining member 160_4 and the additional pixel defining member 160_4A can be different. The pixel defining member 160_4 and the additional pixel defining member 160_4A can be formed of different materials.

[0076] The organic light-emitting layer 160_5 can be deposited to at least cover the pixel defining member 160_4, the additional pixel defining member 160_4A, and the first electrode 160_3. A second electrode 160_6 can be deposited on the organic light-emitting layer 160_5. The first electrode 160_3 and the second electrode 160_6 can receive power to form an electric field according to the control of the semiconductor layer 160_2. In this case, the organic material disposed in the organic light-emitting layer 160_5 can irradiate light by emitting light according to the influence of the electric field. According to an embodiment of this disclosure, no light is emitted in the region of the organic light-emitting layer 160_5 in which the additional pixel defining member 160_4A is disposed. The encapsulation layer 160_7 can be configured to cover the upper side of the second electrode 160_6. The material of the encapsulation layer 160_7 can be the same as the material of the encapsulation layer 160_7 mentioned above in the description of the first type sub-pixel structure 201. Because the encapsulation layer 160_7 is disposed, an air gap may not be included between the light-transmitting protective layer 160_8 and the second electrode 160_6. The second shielding member 162BM and the third shielding member 162BMA can be disposed between the encapsulation layer 160_7 and the light-transmitting protective layer 160_8. At least a portion of the second shielding member 162BM can be positioned in a first direction perpendicular to the front surface of the display 160. Figure 3a It overlaps with pixel-limiting member 160_4 in the z-axis direction.

[0077] Regarding the first direction, the second shielding member 162BM may be configured to cover a portion of the perimeter of the pixel defining member 160_4 (e.g., the perimeter in the outward direction relative to the first electrode 160_3). The second shielding member 162BM may have the same or similar configuration as the second shielding member 162BM mentioned above in the first type sub-pixel structure 201. A third shielding member 162BMA may be disposed between the second shielding members 162BM. Furthermore, the third shielding member 162BMA may be configured to overlap at least a portion of the additional pixel defining member 160_4A with respect to the first direction. The width of the pixel defining member disposed in the second type sub-pixel structure 202 may be the same as or smaller than the width of the pixel defining member disposed in the first type sub-pixel structure 201.

[0078] Regarding the first direction, the pixel defining member 160_4 and the additional pixel defining member 160_4A in the second type sub-pixel structure 202 can have the same width. The linewidths of the pixel defining member 160_4 and the additional pixel defining member 160_4A can be different. The linewidths of the pixel defining member 160_4 and the additional pixel defining member 160_4A can vary depending on the color of the sub-pixel. For example, the width of the pixel defining member 160_4 in the pixel structure corresponding to the second type blue sub-pixel 162B can be greater than the width of the pixel defining member 160_4 in the pixel structure corresponding to the second type red sub-pixel 162R, and the width of the pixel defining member 160_4 in the pixel structure corresponding to the second type red sub-pixel 162R can be greater than the width of the pixel defining member 160_4 in the pixel structure corresponding to the second type green sub-pixels 162Ga and 162Gb. The width of the additional pixel limiting member 160_4A set in the pixel structure corresponding to the second type blue sub-pixel 162B can be greater than the width of the additional pixel limiting member 160_4A set in the pixel structure corresponding to the second type red sub-pixel 162R. The width of the additional pixel limiting member 160_4A set in the pixel structure corresponding to the second type red sub-pixel 162R can be greater than the width of the additional pixel limiting member 160_4A set in the pixel structure corresponding to the second type green sub-pixels 162Ga and 162Gb.

[0079] The second type of subpixel structure 202 may include a second opening 162_1 of a third size 162W1 formed by a second shielding member 162BM and a third shielding member 162BMA. The second opening 162_1 may be configured for a micropixel. The second opening 162_1 may have the same or similar size. Regardless of the color of the micropixel, the second opening 162_1 may have the same size, for example, the third size 162W1. For example, regarding already... Figure 2a or Figure 2b The openings (or the gap between the second shielding member 162B1 and the third shielding member 162BMA or the opening between the second shielding member 162B3 and the third shielding member 162BMA) of the structure of the first blue micropixel 162B1, the second blue micropixel 162B2, the third blue micropixel 162B3, the fourth blue micropixel 162B4, the first red micropixel 162R1, the second red micropixel 162R2, the third red micropixel 162R3 and the fourth red micropixel 162R4, the first green micropixel 162G1, the second green micropixel 162G2, the third green micropixel 162G3 and / or the fourth green micropixel 162G4) may have the same or similar dimensions.

[0080] The size of the opening and the size of the light-emitting region (the interval or area between the pixel defining member and the additional pixel defining member) of the pixel structure corresponding to the blue micropixels 162B1a, 162B1b, 162B1c, and 162B1d can be the same. The size of the opening and the size of the light-emitting region (the interval or area between the pixel defining member and the additional pixel defining member) of the pixel structure corresponding to the red micropixels 162R1a, 162R1b, 162R1c, and 162R1d can be different. For example, the size of the opening of the pixel structure corresponding to the red micropixels 162R1a, 162R1b, 162R1c, and 162R1d can be a first size larger than the size of the light-emitting region (the interval or area between the pixel defining member and the additional pixel defining member). The size of the opening of the pixel structure corresponding to the green micropixels 162G1a, 162G1b, 162G1c, and 162G1d can be a second size larger than the size of the light-emitting region (the interval or area between the pixel defining member and the additional pixel defining member) (e.g., the second size is larger than the first size).

[0081] In the above structure, the display 160 includes first-type subpixels 161 and second-type subpixels 162, and may optionally include a screen with an adjustable viewing angle. In this process, based on the drive for light emission at a relatively small viewing angle (small viewing angle or small angle) in the second-type subpixel structure 202, while simultaneously making the heights of the first-type subpixel structures 201 and 201 uniform, the display 160 of this disclosure can support a personal mode or a privacy mode (e.g., a mode for limiting the light emission angle so that a third party cannot easily observe at least a portion of the screen image of the display 160). Furthermore, the display 160 of this disclosure may include a second-type subpixel structure 202, which provides a narrow viewing angle based on a structure in which there is no air gap between the organic light-emitting layer and the encapsulation layer or the electrode layer and the encapsulation layer, so that neither folding nor bending is possible.

[0082] Figure 2a , Figure 2b and Figure 3a A second shielding member 162BM is shown dividing subpixels in a second type pixel 160b, but this disclosure is not limited thereto. For example, the second shielding member 162BM may be configured to surround at least a portion of the perimeter of the second type pixel 160b, and no separate member may be provided between subpixels 162R, 162Ga, 162Gb, and 162B. In the second type pixel 160b, the portion of the subpixel covered by the shielding member may include the portion of the subpixel that does not emit light due to the provision of the pixel defining member. The pixel defining member provided in the second type pixel 160b may be aligned with the shielding member, and the width of the pixel defining member may be greater than the width of the shielding member between two or more openings, so that some non-emitting subpixels may be exposed through multiple openings. The multiple openings provided by the shielding members 162BM and 162BMA in the second type pixel 160b may have substantially the same width. In the first type pixel 160a, the first shielding member 161BM may be provided in the region of the encapsulation layer. Therefore, the subpixels of the first type pixel 160a may be divided by the multiple openings.

[0083] Reference Figure 3b It can be seen that even within a range of 80 to 85 degrees from the direction perpendicular to the front surface of the display 160, the first type sub-pixel 161 has a luminance ratio of approximately 10% or greater (relative to the luminance measured in the direction perpendicular to the display 160). It can also be seen that within a range of 40 degrees from the direction perpendicular to the front surface of the display 160, the second type sub-pixel 162 has a luminance ratio of approximately 10% or less (relative to the luminance measured in the direction perpendicular to the display 160). Therefore, based on the first viewing angle of the operation of the first type sub-pixel 161 (or based on the viewing angle of simultaneous operation of the first type sub-pixel 161 and the second type sub-pixel 162), which has a horizontal angle of approximately 80 to 85 degrees in the upward / downward and / or leftward / rightward directions relative to a line perpendicular to the front surface of the display 160, the second viewing angle of the screen of the display 160 based on the operation of the second type sub-pixel 162 has a horizontal angle of approximately 40 degrees in the upward / downward and / or leftward / rightward directions, and outside the viewing angle range, only 10% or less of the light compared to the front surface can be seen. Therefore, when the screen is configured based on the second type of sub-pixel 162, the brightness on the side surface can be low, making it difficult to recognize the screen image of the display b160.

[0084] In various embodiments of this disclosure, an example is provided of dividing the light-emitting region of a sub-pixel by providing an additional pixel-defining member 160_4A between the pixel-defining members 160_4. However, in this regard, various embodiments of this disclosure may include replacing the additional pixel-defining member 160_4A by removing a portion of the second electrode. (Refer to...) Figure 3c The light-emitting area of ​​the corresponding sub-pixel can be removed by providing a removal area 160_4b, as shown in... Figure 3b Separated as shown in the image, the area 160_4b was removed from the set portion. Figure 3b The region of the additional pixel defining member 160_4A shown corresponds to a portion of the second electrode. Therefore, the location and form of the shielding member described in the embodiments of this disclosure can be described as a structure in which it is configured to correspond to region 160_4b, from which a portion of the second electrode has been removed. Regarding the separation of the sub-pixel light-emitting region for adjusting the sub-pixel viewing angle, the organic light-emitting layer 160_5 can also be removed in addition to the second electrode 160_6. For example, the removed region 160_4b may include a region from which at least one of the second electrode 160_6 and the organic light-emitting layer 160_5 has been removed.

[0085] Figure 4a This is a view illustrating an example of comparing the dimensions of a first type of subpixel and micropixel according to an embodiment of this disclosure.

[0086] Reference Figures 2a to 4a As shown in 401, the pixel structure 201 corresponding to the first type sub-pixel 161 may have an organic light-emitting layer S1a. A first electrode with the same or smaller size as the organic light-emitting layer S1a may be disposed below the organic light-emitting layer S1a, and a second electrode with the same or larger size as the organic light-emitting layer S1a may be disposed on the organic light-emitting layer S1a. The aforementioned pixel defining member S1b may be disposed at the periphery of the organic light-emitting layer S1a. Therefore, a portion of the periphery of the organic light-emitting layer S1a may overlap with the pixel defining member S1b. The light-emitting region S1c (e.g., Figure 3a The luminescent area 161_2 can be passed through the first opening between the second shielding member 162BM. Figure 3a The first opening 161_1) is exposed to the outside. The luminescent region S1c can be the remaining region of the organic luminescent layer S1a, which is exposed in the upward / downward direction (e.g., Figure 3a The z-axis direction of the light-emitting region S1c does not overlap with the pixel-defined component S1b. The width "d" of one side of the light-emitting region S1c can be... Figure 3aThe width of one side of the light-emitting region 161_2 described herein. The light-emitting region S1c has been described as a square shape with all four sides having the same width, but this disclosure is not limited thereto. For example, the lateral width and vertical width of the light-emitting region S1c may be different. As another example, the shape of the light-emitting region S1c may include a circle or a polygon.

[0087] As indicated by 403, the pixel structure 202 corresponding to the second type sub-pixel 162 may include an organic light-emitting layer S2a. The organic light-emitting layer S2a may have the same dimensions as the organic light-emitting layer S1a of the pixel structure 201 corresponding to the first type sub-pixel 161 described above. A first electrode with dimensions equal to or smaller than those of the organic light-emitting layer S2a may be disposed below the organic light-emitting layer S2a, and a second electrode with dimensions equal to or larger than those of the organic light-emitting layer S2a may be disposed on the organic light-emitting layer S2a. Pixel defining member S2b1 (e.g., Figure 3a The 160_4) can be disposed at the periphery of the organic light-emitting layer S2a, with an additional pixel defining member S2b2 (e.g., Figure 3a (160_4A) can be disposed at least a portion of the central portion of the organic light-emitting layer S2a. A portion of the perimeter of the organic light-emitting layer S2a can at least partially overlap with the pixel defining member S2b1, and the central portion of the organic light-emitting layer S2a can at least partially overlap with the additional pixel defining member S2b2 (e.g., relative to a reference). Figure 3a The second shielding member 162BM can be disposed at a position corresponding to the perimeter of the pixel structure 202 corresponding to the second type sub-pixel 162, and the third shielding member 162BMA can be disposed at a position corresponding to the point between micropixels in the structure of the second type sub-pixel 162. At least the light-emitting regions S1c1, S1c2, S1c3 and S1c4 can pass through the opening region formed by the second shielding member 162BM and the third shielding member 162BMA (e.g., Figure 3a The second opening 162_1) of the third dimension 162W1 described in the text is exposed. The dimension d / 2 on one side of each of the light-emitting regions S1c1, S1c2, S1c3, and S1c4 of the micropixel can be related to... Figure 3aThe second type of sub-pixel 162 has the same size on one side of the light-emitting region S1c of the pixel structure 202. It has been described that the light-emitting regions S1c1, S1c2, S1c3, and S1c4 of the micropixel have a square shape with four sides of equal width, but this disclosure is not limited thereto. For example, the lateral and vertical widths of the light-emitting regions S1c1, S1c2, S1c3, and S1c4 may be different. As another example, the shape of the light-emitting regions S1c1, S1c2, S1c3, and S1c4 of the micropixel may include a circular or polygonal shape, and essentially, the light-emitting regions S1c1, S1c2, S1c3, and S1c4 may have the same shape or the same size.

[0088] The widths of pixel defining member S2b1 and additional pixel defining member S2b2 can be the same. For example, the size of the organic light-emitting layer S1a of the pixel structure 201 corresponding to the first type sub-pixel 161 and the size of the organic light-emitting layer S2a of the pixel structure 202 corresponding to the second type sub-pixel 62 can be the same or similar. The size of the opening region (e.g., the first opening 161_1 of the first size 161W1) included in the first type sub-pixel 162 can be the same as or similar to the sum of the sizes of the opening region (e.g., the second opening 162_1 of the third size 162W1) included in the second type sub-pixel 162 between the second shielding member 162BM and the third shielding member 162BMA. In order to achieve uniform brightness during the driving of the display 160, the sum of the sizes of the light-emitting regions S1c1, S1c2, S1c3, and S1c4 of the micropixel can be the same as the size of the light-emitting region S12 of the first type sub-pixel 161.

[0089] Figure 4b This is a view illustrating an example of comparing the dimensions of a first type of subpixel and a micropixel in practical application according to embodiments of the present disclosure.

[0090] Reference Figure 4bAs shown, the first type sub-pixels 161B, 161R, 161Ga, and 161Gb (e.g., sub-pixels included in the first type pixel 160a or sub-pixels included in a modified first type pixel 160a) may include a first light-emitting region S3a (e.g., the region of the organic light-emitting layer and the electrode layer that overlaps with the organic light-emitting layer in the upward / downward direction) and a pixel-defining member region S3b defining the perimeter of the first light-emitting region S3a. The pixel-defining member region S3b may define the first light-emitting region S3a and overlap with at least a portion of the first light-emitting region S3a. The interior of the corner region of the pixel-defining member region S3b facing the first light-emitting region S3a may be rounded. As described above, since the corner region of the first light-emitting region S3a is rounded, the luminance of the corner region of the first light-emitting region S3a (in which its two perimeters meet each other) can be measured to be relatively lower than that of the central portion of the first light-emitting region S3a. Due to various factors affecting OLED characteristics (e.g., changes in OLED light emission characteristics due to PDL steps, variations in PDL patterning resolution, narrow-angle emission of the OLED dipole emitter via the PDL, and OLED degradation due to the PDL material), the periphery of the first light-emitting region S3a can exhibit relatively low luminance characteristics compared to its central portion. Therefore, as the periphery and corner regions of the first light-emitting region S3a increase, relatively low luminance characteristics can be exhibited. The second type sub-pixels 162B, 162R, 162Ga, and 162Gb can be provided by dividing the dimensions of the first type sub-pixels 161B, 161R, 161Ga, and 161Gb using pixel-defining members, and the corner regions of the divided second light-emitting regions S3a1, S3a2, S3a3, and S3a4 of each of the second type sub-pixels 162B, 162R, 162Ga, and 162Gb can be rounded using pixel-defining members. As the sub-pixel size decreases, the rounded portions occupy a higher proportion. Therefore, even though the sum of the areas of the second light-emitting regions S3a1, S3a2, S3a3, and S3a4 of the second type sub-pixels 162B, 162R, 162Ga, and 162Gb defined by the pixel-defined component regions S3b1, S3b2, S3b3, and S3b4 corresponds to the first light-emitting region S3a of the first type sub-pixels 161B, 161R, 161Ga, and 161Gb, it will still exhibit relatively low luminance and low lifetime characteristics. Therefore, the sum of the sizes of the second light-emitting regions S3a1, S3a2, S3a3, and S3a4 of the second type sub-pixels 162B, 162R, 162Ga, and 162Gb can be greater than the sum of the sizes of the first light-emitting region S3a of the first type sub-pixels 161B, 161R, 161Ga, and 161Gb.In this regard, based on Equation 1 below, the conditions for equal luminance of the first type sub-pixels 161B, 161R, 161Ga and 161Gb and the second type sub-pixels 162B, 162R, 162Ga and 162Gb can be calculated.

[0091] Twide.uniform+Twide.edge=4(Tnarrow.uniform+Tnarrow.edge)…Equation 1

[0092] In Equation 1, Twide.uniform is Lwide.uniform × Awide.uniform, Twide.edge is Lwide.edge × Awide.edge, Tnarrow.uniform is Lnarrow.uniform × Anarrow.uniform, and Tnarrow.edge is Lnarrow.edge × Anarrow.edge. Twide.uniform can represent the total amount of light in a region with uniform luminous properties within the first-type sub-pixels 161B, 161R, 161Ga, and 161Gb. Lwide.uniform can be the amount of light per unit area, which can be obtained by multiplying it by Awide.uniform to get the total amount of light. In Equation 1, pixels can be categorized into first-type sub-pixels 161B, 161R, 161Ga, and 161Gb (e.g., wide pixels) and second-type sub-pixels 162B, 162R, 162Ga, and 162Gb (e.g., narrow pixels, narrow-viewing-angle pixels). Regions based on luminous characteristics can be categorized as uniform or edge. An edge can be defined as a region where luminance decreases due to various factors (such as boundary deviations of the luminous portion due to PDL patterning deviations, degradation of luminance characteristics of the luminous portion due to PDL steps, etc.), and rounded corners can be included in the edge. According to an embodiment, when assuming Lwide.edge / Lwide.uniform = Lnarrow.edge / Lwide.uniform is 1, for RGB sub-pixels, the sub-pixel area loss caused by rounded corners can reduce luminance by 92.13%, 85.99%, and 95.32%, respectively. Therefore, as a measure to compensate for the aforementioned reduction in luminance, when the size of the second type of sub-pixels is compensated (e.g., when the area of ​​the RGB sub-pixels is designed to be increased by 109%, 116%, or 105%), the area loss and luminance reduction at the corners of the rounded shape can be compensated, making the total light intensity of the first type of sub-pixels and the second type of sub-pixels the same (Twide.uniform + Twide.edge = Tnarrow.uniform + Tnarrow.edge). The RGB ratio can be changed depending on the pixel size of the RGB and other elements (e.g., RGB material properties). As described above, by forming a structure such that the sum of the sizes of the second type of sub-pixels 162B, 162R, 162Ga, and 162Gb can be a certain size larger than the size of the corresponding first type of sub-pixels, thereby making the total light intensity of the first type of sub-pixels and the second type of sub-pixels the same, the display according to the embodiments of this disclosure can improve the luminance characteristics, color deviation, and lifetime characteristics of the second type of sub-pixels 162B, 162R, 162Ga, and 162Gb.Furthermore, the display disclosed herein can prevent problems such as burn-in deviation and light spots.

[0093] Figure 5 This is a view illustrating an example of a partial structure of a display associated with a light-emitting region of a second type of subpixel structure according to an embodiment of this disclosure.

[0094] Reference Figure 5 As shown, at least a portion of the second type sub-pixel structure 202 according to the embodiment may include a semiconductor layer 160_2, a first electrode 160_3, an organic light-emitting layer 160_5, and / or a second electrode 160_6. An additional pixel defining member 160_4A may be disposed in the central portion of the organic light-emitting layer 160_5, simultaneously contacting the first electrode 160_3. In the above-described second type sub-pixel structure 202, because the additional pixel defining member 160_4A is disposed in at least a portion of the central portion of the first electrode 160_3, the light-emitting region of the organic light-emitting layer 160_5 may be separated to the left and right relative to the additional pixel defining member 160_4A, as shown. Therefore, the second type sub-pixel structure 202 may include a non-light-emitting region 162_2 corresponding to the region in which the additional pixel defining member 160_4A is disposed, and light-emitting regions 162_1a and 162_1b disposed to the left and right of the non-light-emitting region 162_2, respectively. Although the luminescent regions 162_1a and 162_1b are depicted in the accompanying drawings as being positioned to the left and right of the non-luminescent region 162_2 relative to the two-dimensional plane, the above reference... Figures 2a to 3c In the first direction described (e.g., the z-axis direction), the non-light-emitting region 162_2 may include a rectangular perimeter corresponding to the second sub-pixel structure 202 and a cross-shaped region at the center of the rectangular shape. The light-emitting regions 162_1a and 162_1b may include regions disposed in four quadrants relative to the cross-shaped region. By determining a ratio between the height between the light-emitting layer and the shielding member and the height between the light-emitting members such that this ratio becomes a specific value, the display 160 of this disclosure can provide uniform screen characteristics in a normal mode at a first viewing angle and in a privacy mode at a second viewing angle (e.g., a narrow viewing angle). For example, when the panel thickness is 30 μm, the width of the light-emitting region (or light-emitting member) of the first type sub-pixel structure 201 can be about 25 μm, and the width of the separate light-emitting regions of the second type sub-pixel structure 202 can be 12.5 μm. Thus, by making the sum of the widths of the separate light-emitting regions of the second type sub-pixel structure 202 the same as the width of the light-emitting region of the first type sub-pixel structure 201 to make the panel thickness ratio similar, the screen characteristics can become uniform.

[0095] Figure 6This is a view showing a partial structure of a display that compares the structures of pixels of a second type of sub-pixel according to an embodiment of this disclosure.

[0096] Reference Figure 2a and Figure 6 The blue micropixel structure 601 may include an organic light-emitting layer and second electrodes 160_5 and 160_6. The second electrodes 160_5 and 160_6 cover portions of the additional pixel defining member 160_4A and pixel defining member 160_4 disposed on the opposite periphery of the first blue electrode 160_31, as well as a portion of the exposed portions of pixel defining member 160_4, additional pixel defining member 160_4A, and the first blue electrode 160_31. Although not shown, an additional shielding member may be disposed on the upper end of pixel defining member 160_4. The additional shielding member may be disposed between pixel defining member 160_4 and other shielding members (e.g., 162BM and 161BMA).

[0097] In the blue micropixel structure 601, an encapsulation layer 160_7 covering the organic light-emitting layer and second electrodes 160_5 and 160_6 are disposed on its upper side. A light-transmitting protective layer 160_8 may be disposed on the upper side of the encapsulation layer 160_7. Side members (e.g., portions of the second shielding member 162BM and the third shielding member 162BMA) may be partially disposed between the encapsulation layer 160_7 and the light-transmitting protective layer 160_8. In the above structure, the blue micropixel structure 601 may include a first micropixel opening 162_B1a of a fifth size 162WB1 formed by portions of the second shielding member 162BM and the third shielding member 162BMA. Furthermore, the blue micropixel structure 601 may include a blue micropixel light-emitting region 162_B1b of a sixth size 162WB2. The first micropixel opening 162_B1a of the fifth size 162WB1 and the blue micropixel light-emitting region 162_B1b of the sixth size 162WB2 may have the same size. For example, the length of one side of the first micropixel opening 162_B1a of the fifth size 162WB1 (or the blue micropixel emitting region 162_B1b of the sixth size 162WB2) can be approximately 12.5 μm.

[0098] The red micropixel structure 603 may include an organic light-emitting layer and second electrodes 160_5 and 160_6. The second electrodes 160_5 and 160_6 cover portions of the additional pixel defining member 160_4A and pixel defining member 160_4 disposed on opposite peripheries of the first red electrode 160_32, as well as portions of the exposed portions of the additional pixel defining member 160_4A, pixel defining member 160_4, and second electrodes 160_5 and 160_6. In the red micropixel structure 603, an encapsulation layer 160_7 covering the organic light-emitting layer and the second electrodes 160_5 and 160_6 are disposed on its upper side. A light-transmitting protective layer 160_8 may be disposed on the upper side of the encapsulation layer 160_7. Side members (e.g., a portion of the third shielding member 162BMA and the second shielding member 162BM) may be partially disposed between the encapsulation layer 160_7 and the light-transmitting protective layer 160_8. In the above structure, the red micropixel structure 603 may include a seventh micropixel opening 162_R1a of a seventh size 162WR1 formed by portions of the third shielding member 162BMA and the second shielding member 162BM. Furthermore, the red micropixel structure 603 may include a red micropixel light-emitting region 162_R1b of an eighth size 162WR2. The second micropixel opening 162_R1a of the seventh size 162WR1 and the red micropixel light-emitting region 162_R1b of the eighth size 162WR2 may have the same size. For example, the length of one side of the second micropixel opening 162_R1a of the seventh size 162WR1 (or the red micropixel light-emitting region 162_R1b of the eighth size 162WR2) may be approximately 10 μm.

[0099] As described above, the size of the opening and the light-emitting area of ​​the blue micropixel can be larger than the size of the opening and the light-emitting area of ​​the red micropixel. Similarly, the size of the opening and the light-emitting area of ​​the red micropixel can be larger than the size of the opening and the light-emitting area of ​​the green micropixel.

[0100] Figure 7 This is a view illustrating another example of a second type of subpixel in an embodiment of this disclosure. Figure 8 This illustrates the detection according to an embodiment of the present disclosure. Figure 7 A view of the luminance of the structure of the second type of subpixel.

[0101] Reference Figure 7As shown, the second type of red sub-pixel 162R can be configured such that four red micropixels 162R1, 162R2, 162R3, and 162R4 are adjacent to each other. Because the four red micropixels 162R1, 162R2, 162R3, and 162R4 are disposed on a first electrode, they can be driven as if they were a single red sub-pixel. As shown, in the four red micropixels 162R1, 162R2, 162R3, and 162R4, a red organic light-emitting layer covering the additional pixel defining member 160_4A can be disposed differently. For example, in the third red micropixel 162R3, regarding the first direction ( Figure 3a (In the z-axis direction), a second shielding member 162BM of first width and a third shielding member 162BMA of second width can be disposed on its upper side, and a third red micropixel opening 162_3a can be disposed between the second shielding member 162BM and the third shielding member 162BMA. The width of the second shielding member 162BM and the width of the third shielding member 162BMA can be the same. According to various embodiments, the width of the second shielding member 162BM can be greater than the width of the third shielding member 162BMA.

[0102] The third red micropixel 162R3 may include a light-emitting region 162_R3b (or a light-emitting member). A pixel defining member 160_4 may be disposed to the left of the light-emitting region 162_3b, as shown in the accompanying drawings, and an additional pixel defining member 160_4A may be disposed to its right. The width of the pixel defining member 160_4 and the width of the second shielding member 162BM may be the same, and they may overlap each other in an upward / downward direction relative to a first direction (e.g., a direction perpendicular to the front surface of the display 160). For example, the perimeter of the pixel defining member 160_4 and the perimeter of the second shielding member 162BM may be arranged to coincide with each other about the first direction. The width of the additional pixel defining member 160_4A may be greater than the width of the third shielding member 162BMA, and a portion of the third shielding member 162BMA may overlap with the additional pixel defining member 160_4A about the first direction (e.g., a direction perpendicular to the front surface of the display 160). For example, a perimeter (e.g., the left perimeter) 160_4R3 of the additional pixel defining member 160_4A can be exposed through the opening 162_R3a. In the above structure, the size 162WR2 of the light-emitting region 162_R3b can be smaller than the size 162WR1 of the opening 162_R3a.

[0103] As in the third red micropixel 162R3, the fourth red micropixel 162R4 may also include a light-emitting region 162_R4b. An additional defining member 160_4A may be disposed to the left of the light-emitting region 162_R4b, as shown in the accompanying drawings, and the pixel defining member 160_4 may be disposed to its right. The width of the pixel defining member 160_4 and the width of the second shielding member 162BM may be the same, and they may overlap each other in an upward / downward direction relative to a first direction (e.g., a direction perpendicular to the front surface of the display 160). For example, referring to the accompanying drawings, the left perimeter of the pixel defining member 160_4 and the left perimeter of the second shielding member 162BM may be arranged to coincide with each other about the first direction. The width of the additional pixel defining member 160_4A may be greater than the width of the third shielding member 162BMA, and a portion of the third shielding member 162BMA may overlap with the additional pixel defining member 160_4A about the first direction (e.g., a direction perpendicular to the front surface of the display 160). For example, one perimeter (e.g., the right perimeter) 160_4R4 of the additional pixel defining member 160_4A can be exposed through the opening 162_R4a. In the above structure, the size 162WR2 of the light-emitting region 162_R4b can be smaller than the size 162WR1 of the opening 162_R4a.

[0104] In the above description, since the third red micropixel 162R3 and the fourth red micropixel 162R4 have been illustrated, and the position of the exposed portion of the additional pixel defining member 160_4A is described as being on the left or right side of the additional pixel defining member 160_4A, this disclosure is not limited thereto. For example, depending on the modification of the setting position or shape of the red micropixel, at least a portion of the perimeter (e.g., left perimeter, right perimeter, upper perimeter, or lower perimeter) of the additional pixel defining member 160_4A can be exposed by at least a portion of an opening corresponding to the position where the micropixel is set.

[0105] As shown, the second type of red subpixel 162R can be configured to be adjacent to a second type of blue subpixel 162b comprising four blue micropixels 162B1, 162B2, 162B3, and 162B4. The openings (or gaps) between the shielding members disposed in the four blue micropixels 162B1, 162B2, 162B3, and 162B4 can be the same as the regions (or gaps) between the pixel defining members. Therefore, no pixel defining members (or no additional pixel defining members) can be observed in the four blue micropixels 162B1, 162B2, 162B3, and 162B4. A portion of the red micropixel (e.g., a portion of the first red micropixel 162R1_7a or a portion of the second red micropixel 162R1_7b) can have the same or similar shape as a portion of the blue micropixel (e.g., a portion of the first blue micropixel 162B1_7a or a portion of the second blue micropixel 162B1_7b).

[0106] Reference Figure 8 Regarding the change in luminance detected at the angle of the third red micropixel 162R3, it can be seen that the luminance changes within a relatively small angular variation (e.g., about 0 to 25 degrees) in the central direction (e.g., the direction perpendicular to the front surface of the display 160). Regarding the change in luminance detected at the angle of the fourth red micropixel 162R4, it can be seen that the luminance changes within a relatively large angular variation (e.g., about 20 to 45 degrees) in the central direction (e.g., the direction perpendicular to the front surface of the display 160). Therefore, since a portion of the additional pixel defining member of the third red micropixel 162R3 and a portion of the additional pixel defining member of the fourth red micropixel 162R4 are set to be adjacent to each other, the sum of the luminance changes of the third red micropixel 162R3 and the fourth red micropixel 162R4 (160R3_160R4) can be matched to a luminance change similar to that of the blue micropixels (e.g., 162B3 and 162B4), thereby preventing screen distortion of the display 160.

[0107] Figure 9 This is a view illustrating the configuration related to the viewpoint of a first type of subpixel, the configuration related to the viewpoint of a micropixel, and the configuration related to the viewpoint of a modified micropixel, according to embodiments of the present disclosure. Figure 10 An example of applying micropixels according to embodiments of this disclosure is shown. Figure 11 This is a view illustrating changes in the luminance detection of micropixels modified according to embodiments of the present disclosure.

[0108] Reference Figure 9As shown in 901, the first type of sub-pixel structure 201 may include at least a first light-emitting member 161_2, a pixel-defining member 160_4, and a second shielding member 162BM. The second shielding members 162BM may be spaced apart from each other by a specific interval to form an opening 161W1 (or a first width). The first light-emitting member 161_2 may include Figure 3a The first light-emitting element 161_2 comprises at least a portion of a semiconductor layer 160_2, at least a portion of a first electrode 160_3, at least a portion of an organic light-emitting layer 160_5, and at least one of a second electrode 160_6. The light-emitting range of the first light-emitting element 161_2 can be determined by the pixel-defining element 160_4. For example, the first light-emitting element 161_2 may have a light-emitting range of a first region 161W2 (or a first width). In the first type of sub-pixel structure 201, the first size 161W1 of the first opening 161_1 between the first shielding elements 161BM can be larger than the first region 161W2, resulting in a relatively large viewing angle of the screen. Furthermore, the first type of sub-pixel structure 201 may be located within a range where the first region 161W2 may be located within the range of the first opening 161_1 about a first direction (e.g., the direction perpendicular between the first shielding element 161BM and the pixel-defining element 160_4).

[0109] As shown in 903, the micropixel structure can include the same as described above. Figure 3a The micropixel structure corresponds to a portion of the second type of subpixel structure 202 described herein. The micropixel structure may include at least a second light-emitting member 162_2, a pixel-defining member 160_4, an additional pixel-defining member 160_4A, a second shielding member 162BM, and a third shielding member 162BMA. The second shielding member 162BM and the third shielding member 162BMA may be spaced apart from each other by a specific interval to form a second opening 162_1 of a second size 162W1 (or a second width). The second light-emitting member 162_2 may, for example, include... Figure 3aThe second light-emitting member 162_2 comprises at least a portion of a semiconductor layer 160_2, at least a portion of a first electrode 160_3, at least a portion of an organic light-emitting layer 160_5, and at least one of a second electrode 160_6. The light-emitting range of the second light-emitting member 162_2 can be determined by a pixel-defining member 160_4 and an additional pixel-defining member 160_4A. For example, the second light-emitting member 162_2 may have a light-emitting range of a second region 162W2 (or a second width). In the micropixel structure, the size 162W2 of the second opening 162_1 between the second shielding member 162BM and the third shielding member 162BMA may be similar to or the same as the size of the second region 162W2, such that the viewing angle of the screen is relatively small compared to the first type subpixel structure 201. Furthermore, regarding the first direction (e.g., the direction perpendicular between the first shielding member 161BM and the pixel defining member 160_4), the second region 162W2 of the micropixel structure may be arranged with a second opening 162_1. For example, the position of at least one side of the second region and the position of at least one perimeter shielding member defining the second opening 162W1 are set to coincide with each other perpendicularly with respect to the first direction.

[0110] As shown in 905, the modified micropixel structure 203 may include at least a second light-emitting member 162_2, a pixel-defining member 160_4, an additional pixel-defining member 160_4A, a modified second shielding member 162_BM', and a modified third shielding member 162BMA'. The modified second shielding member 162BM' and the modified third shielding member 162BMA' may be spaced apart from each other by a specific interval to form a third opening 162_1' of a third size 162WE (or a third width). The dimensions of the modified second shielding member 162BM' and the modified third shielding member 162BMA' may be smaller than the dimensions of the pixel-defining member 160_4 and the additional pixel-defining member 160_4A. The dimensions of the modified second shielding member 162BM' and the modified third shielding member 162BMA' may be smaller than the dimensions of the second shielding member 162BM and the third shielding member 162BMA described in the micropixel structure. The second light-emitting member 162_1 may be the same light-emitting member as the second light-emitting member 162_2 of the micropixel structure described above. Therefore, the second light-emitting member 162_2 of the modified micropixel structure 203 can have a light-emitting range of a second region 162W2 (or a second width). In the modified micropixel structure 203, the size 162WE of the third opening 162_1′ between the modified second shielding member 162BM' and the modified third shielding member 162BMA' is smaller than the size 161W1 of the opening 161_1 and the second size 162W1 of the opening 162_1, so that it can exhibit relatively high brightness performance compared with the micropixel structure, while the viewing angle of the screen is similar to that of the micropixel structure.

[0111] Reference Figure 10 The modified micropixel structure 203 may include a light-emitting region 162_2, a modified third shielding member 162BMA' (or a modified second shielding member 162BM'), and an extended pixel-defining member 160_4E. The size of the light-emitting region 162_2 may be the same as or similar to one-quarter (or half in the case of one side) of the area of ​​the light-emitting region 161_2 of the first type subpixel structure 201. When the width of the modified third shielding member 162BMA' is less than the width of the third shielding member 162MBA of the micropixel structure, at least a portion of the additional pixel-defining member 160_4A (or pixel-defining member 160_4) may be exposed through the third opening 162_1' according to the third shielding member 162BMA. The additional pixel-defining member 160_4A (or pixel-defining member 160_4) disposed in the extended pixel-defining member 160_4E may have the same width and size as the additional pixel-defining member 160_4A described in the micropixel structure.

[0112] Reference Figure 11 As can be seen, as the size of the difference "x" between the side of the second opening 162_1 and the side of the third opening 162_1′ gradually increases, the luminance detection change according to the angle change occurs later. For example, it can be seen that a value of x of 0 corresponds to a luminance detection change of 0 degrees (e.g., perpendicular to the display 160) for the second opening 162_1 of the micropixel structure 202, while when x is 2.5 (e.g., when one side of the third opening 162_1′ is 2.5 μm larger than one side of the second opening 162_1), a luminance detection change occurs from an angle of about 10 degrees or greater.

Figure 12b This is a view showing a second structure of a second type of sub-pixel according to an embodiment of the present disclosure and a view based on the second structure. Figure 12c This is a view showing the third structure of a second type of sub-pixel according to an embodiment of the present disclosure and a view based on the third structure. Figure 12d This is a view showing a first structure of a second type of sub-pixel according to an embodiment of the present disclosure and a view based on the first structure.

[0114] Reference Figure 12aAs shown in the second type subpixel structure 1201a of the first structure, when viewed in a first direction (e.g., a direction perpendicular to the front surface of the display 160), the opening region and the light-emitting region of the shielding member can overlap each other, and the individual pixel-defining members can be concealed from external exposure. The second type subpixel structure 1201a of the first structure may include a first blue subpixel 162B_1, a first red subpixel 162R_1, and a first green subpixel 162G_1. The first blue subpixel 162B_1 may include a first blue micropixel 162B1, a second blue micropixel 162B2, a third blue micropixel 162B3, and / or a fourth blue micropixel 162B4. The first type red subpixel 162R_1 may include a first red micropixel 162R1, a second red micropixel 162R2, a third red micropixel 162R3, and / or a fourth red micropixel 162R4. The first type of green sub-pixel 162G_1 may include a first green micropixel 162G1, a second green micropixel 162G2, a third green micropixel 162G3, and / or a fourth green micropixel 162G4. The light-emitting areas of the aforementioned micropixels can be aligned with the openings of the shielding member.

[0115] As can be seen, in the second type of sub-pixel structure 1201a of the first structure, as shown in 1203a, the viewing angle change of the first blue sub-pixel 162B1 is gentler than that of the first red sub-pixel 162R_1, and the viewing angle change of the first red sub-pixel 162R_1 is gentler than that of the first green sub-pixel 162G_1. Furthermore, as can be seen, in the second type of sub-pixel structure of the first structure, as shown in 1205a, the radiation angle dependence of the first blue sub-pixel 162B_1 does not coincide with the radiation angle dependence of the first red sub-pixel 162R_1 and the first green sub-pixel 162G_1. Therefore, when using the second type of sub-pixel structure of the first structure, color changes can occur differently depending on the viewing angle of the display 160, and screen defects can be identified accordingly.

[0116] Reference Figure 12bWhen viewed in a first direction (e.g., a direction perpendicular to the front surface of display 160), the structure of the second type sub-pixel structure 1201b of the second structure may not coincide with the opening regions of the shielding members in the red and green sub-pixels of the light-emitting region, but may coincide with the opening regions in the blue sub-pixels. In the second type sub-pixel structure 1201b of the second structure, the sizes of all opening regions of the shielding members of the micropixels may be the same or similar. The opening regions and light-emitting regions of the shielding members of the blue micropixels included in the second blue sub-pixel 162B_2 may be arranged with reference to the first direction, so that the pixel defining members in the blue micropixels included in the second blue sub-pixel 162B_2 may have a structure that is not exposed to the opening regions. The opening regions of the shielding members of the red micropixels included in the second red sub-pixel 162R_2 are arranged with reference to the first direction as well as the light-emitting region and pixel defining members of the red micropixels, so that a portion of the pixel defining members of the first size of the red micropixels may be exposed through the opening regions. The opening region of the shielding member of the green micropixel included in the second green sub-pixel 162G_2, along with the light-emitting region and pixel defining member of the green micropixel, can be arranged with reference to a first direction (the direction in which the display is viewed from the front surface of the display), and a portion of the pixel defining member of the second size (larger than the first size) of the green micropixel can be exposed through the opening region. Referring to the second red sub-pixel 162R_2 and the green sub-pixel 162G_2, the exposed pixel defining member can surround at least a portion of the perimeter of the sub-pixel.

[0117] As can be seen from the second type of sub-pixel structure 1201b of the second structure, as shown in 1203b, the viewing angle changes of the second blue sub-pixel 162B_2, the second red sub-pixel 162R_2, and the second green sub-pixel 162G_2 exhibit similar curves. Furthermore, as can be seen from the second type of sub-pixel structure of the second structure, as shown in 1205b, the dependence of the radiation angles of the second red sub-pixel 162R_2 and the second green sub-pixel 162G_2 is essentially overlapping, but the dependence of the radiation angle of the second blue sub-pixel 162B_2 does not overlap with the dependence of the radiation angles of the second red sub-pixel 162R_2 and the second green sub-pixel 162G_2.

[0118] Reference Figure 12c In the second type of sub-pixel structure 1201c of the third structure, when viewed in a first direction (e.g., a direction perpendicular to the front surface of the display 160), the third blue sub-pixel 162B_3 can have the same characteristics as... Figure 12a or Figure 12b The blue sub-pixels described in the text have the same or similar structures.

[0119] In the second type of sub-pixel structure 1201c of the third structure, the third green sub-pixel 162G_3 can be configured such that some light-emitting areas and some pixel-defining members are exposed through the opening area of ​​the shielding member. For example, the green micropixels included in the third green sub-pixel 162G_3 can be configured such that the light-emitting area and the pixel-defining member each occupy half of the light-emitting area. The pixel-defining members of the green micropixels in the third green sub-pixel 162G_3 can be configured to be adjacent to each other in the central portion of the green sub-pixel.

[0120] The third red sub-pixel 162R_3 can be configured such that some light-emitting areas and some pixel-defining members can be exposed through the opening area of ​​the shielding member. For example, the red micropixels included in the third red sub-pixel 162R_3 can be configured such that the light-emitting areas occupy an area larger than the pixel-defining members. The pixel-defining members of the red micropixels in the third red sub-pixel 162R_3 can be configured to be adjacent to each other in the central portion of the red sub-pixel.

[0121] As can be seen, in the second type of sub-pixel structure 1201c of the third structure, as shown in 1203c, the viewing angle changes of the third blue sub-pixel 162B_3, the third red sub-pixel 162B_3, and the third green sub-pixel 162G_2 exhibit very high similarity, as indicated in 162RGB. Furthermore, it can be seen that in the second type of sub-pixel structure of the third structure, as shown in 1205c, the dependence of the radiation angles of the third blue sub-pixel 162B, the third red sub-pixel 162R, and the third green sub-pixel 162G largely overlaps with each other.

[0122] Reference Figure 12d In the second type of sub-pixel structure 1201d of the fourth structure, when viewed in a first direction (e.g., a direction perpendicular to the front surface of the display 160), the fourth blue sub-pixel 162B_4 can have the same characteristics as... Figure 12a or Figure 12b The blue sub-pixels described in the text have the same or similar structures.

[0123] The fourth green sub-pixel 162G_4 can be configured such that some light-emitting areas and some pixel-defining components can be exposed through the opening area of ​​the shielding component. For example, the green micropixels included in the fourth green sub-pixel 162G_4 can be configured such that the light-emitting areas and pixel-defining components each occupy half of the light-emitting area. The light-emitting areas of the green micropixels in the fourth green sub-pixel 162G_4 can be configured to be adjacent to each other in the central portion of the green sub-pixel.

[0124] The fourth red sub-pixel 162R_4 can be configured such that some light-emitting areas and some pixel-defining components can be exposed through the opening area of ​​the shielding component. For example, the red micropixels included in the fourth red sub-pixel 162R_4 can be configured such that the light-emitting areas occupy an area larger than the pixel-defining components. The light-emitting areas of the red micropixels in the fourth red sub-pixel 162R_4 can be configured to be adjacent to each other in the central portion of the red sub-pixel.

[0125] It can be seen that in the second type of sub-pixel structure 1201d of the fourth structure, as shown in 1203d, similar to 1203c, the viewing angle changes of the fourth blue sub-pixel 162B_4, the fourth red sub-pixel 162R_4, and the fourth green sub-pixel 162G_4 exhibit very high similarity, as indicated in 162RGB. Furthermore, it can be seen that in the second type of sub-pixel structure of the fourth structure, as shown in 1205d, similar to 1205c, the dependence of the radiation angles of the fourth blue sub-pixel 162B, the fourth red sub-pixel 162R, and the fourth green sub-pixel 162G largely overlaps with each other.

[0126] Figure 13 This is a view illustrating an example of a method for operating an electronic device according to an embodiment of the present disclosure.

[0127] Reference Figure 13 In operation 1301, the processor 150 of the electronic device 100 can identify whether the display 160 is turned on (or whether the off state has changed to the on state).

[0128] In operation 1301, when the display 160 is not turned on (or is in a closed state), the processor 150 can control the execution of specific functions in operation 1303. For example, the processor 150 can output audio signals processed in the background or support voice communication functions while keeping the display 160 in a closed state. Furthermore, the processor 150 can control the collection of sensor information during specific time periods or collect it in real time by activating sensors that are currently in a closed state.

[0129] When the display 1670 is on, in operation 1305, the processor 150 can identify the application or setting (or setting information 141). For example, the processor 150 can identify the type of application being requested to be executed. Furthermore, the processor 150 can identify which setting has been applied by recognizing the setting information associated with the on state of the display 160.

[0130] When the first type is set (or the first type of application is requested to be executed), then in operation 1307, the processor 140 can perform control so that the first type of sub-pixel ( Figure 1161 (or the first type of sub-pixel set or the first type of sub-pixel group) and the second type of sub-pixel ( Figure 1 The first type of application can refer to an application that can be operated by turning on the entire display 160 regardless of the viewing angle. For example, the first type of application may include an application that supports access to a portal web server.

[0131] When the second type of application is set (or a request is made to execute the second type of application) in operation 1305, then in operation 1309, the processor 150 can execute control to turn off the first type of subpixel and turn on the second type of subpixel. The second type of application could, for example, mean an application designed to make it difficult for a third party to view the screen of the display 160 from the side, or to prevent a third party from viewing the screen of the display 160, by turning on some pixels (e.g., the second type of subpixel) that provide a relatively small viewing angle for the display 160, according to the user's intent. For example, the second type of application could include an application that supports functions such as accessing secure channels, accessing a gallery, and composing messages.

[0132] In operation 1311, processor 150 can identify whether an event related to the end of operation of display 160 has occurred. When no event related to the end of operation of display 160 exists, processor 150 branches to the operation prior to operation 1305 to perform the operation again or maintain the previous state (e.g., operation 1307 or operation 1309).

[0133] The embodiments of this disclosure facilitate selective operation of privacy mode and normal mode. Furthermore, embodiments of this disclosure can provide narrow-viewing-angle OLED pixels (or subpixels or micropixels) associated with privacy mode operation, and aid in viewing the display without reducing brightness by preventing luminance (or brightness) at normal viewing angles and brightness at narrow viewing angles from being affected in the direction perpendicular to the front surface of the display. Embodiments of this disclosure can provide narrow-viewing-angle functionality in four directions during privacy mode operation, thus providing effective viewing angle shut-off functionality in landscape or portrait modes. Because embodiments of this disclosure are compatible with AMOLED Y-OCTA technology, the optical blocking layer (e.g., BM or metal) is compatible with AMLED application technology, and the panel can be manufactured without additionally increasing panel thickness. Furthermore, when the above-described… Figures 12b to 12d When any one of the micropixel structures is used, the screen can be viewed without causing problems such as color shift, and the brightness or luminance can be maintained at a specific value or higher.

[0134] As described above, a display device including an organic light-emitting display (OLED) panel according to embodiments of the present disclosure may include a pixel layer in which OLED pixels corresponding to a plurality of pixels are disposed, and an encapsulation layer that encapsulates the pixel layer without air gap. In the pixel layer, a plurality of pixels including sub-pixels of three colors, red (R), green (G), and blue (B), may include a first pixel group and a second pixel group. The second pixel group has a viewing angle smaller than that of the first pixel group. A shielding member disposed on at least one surface of the encapsulation layer may form a plurality of openings. At least one sub-pixel included in the second pixel group may be divided by at least two of the plurality of openings. The pixels of the first pixel group and the second pixel group may be driven in a normal mode, and the pixels of the second pixel group may be driven in a narrow viewing angle mode, thereby displaying the screen with a narrow viewing angle narrower than that in the normal mode.

[0135] Multiple openings in a shielding member can have substantially the same width.

[0136] The portion of the subpixels of the second pixel group covered by the shielding member between two or more openings may include an area in which some subpixels do not emit light due to the arrangement of the pixel-limiting member.

[0137] The pixel defining member can be aligned with the shielding member (e.g., arranged perpendicular to a first direction of viewing the display from the front surface of the display), and the width of the pixel defining member can be formed to be greater than the width of the shielding member between two or more openings, so that some non-emitting sub-pixels are included in the multiple openings.

[0138] The display may further include at least one processor associated with driving the pixel layer, the processor being able to perform control such that pixels of the first pixel group are turned off in narrow viewing angle mode or displayed in a color with a specific grayscale value.

[0139] The processor can perform control to adjust a specific grayscale value based on the brightness adjustment.

[0140] The processor can set the contrast of the first pixel group in narrow viewing angle mode to the contrast of the first pixel group in normal mode.

[0141] As described above, a display device according to embodiments of the present disclosure may include a display comprising a plurality of pixels, each of the plurality of pixels comprising a plurality of sub-pixels, the plurality of sub-pixels comprising a first type of sub-pixel observed from a first viewing angle and a second type of sub-pixel observed from a second viewing angle narrower than the first viewing angle.

[0142] The first type of subpixel may include a pixel defining member surrounding at least a portion of the perimeter of the subpixel, and the second type of subpixel may include additional defining members that divide the region of the subpixel into a plurality of micropixels.

[0143] The display device may further include an encapsulation layer covering a plurality of micropixels, a light-transmitting protective layer covering at least a portion of the encapsulation layer, and a shielding member disposed between the encapsulation layer and the light-transmitting protective layer. The shielding member may include a first shielding member arranged corresponding to a pixel defining member of a first type of subpixel, a second shielding member arranged corresponding to the perimeter of a second type of subpixel, and a third shielding member arranged corresponding to an additional pixel defining member.

[0144] The display device may include multiple openings formed by a second shielding member and a third shielding member, and the multiple openings may have the same size.

[0145] The size of the luminescent region of a micropixel, as observed through multiple openings, can vary for various colors (e.g., red, green, blue).

[0146] Among the micropixels observed through the plurality of openings, the size of the light-emitting area of ​​the blue micropixel can be larger than the size of the light-emitting area of ​​the red micropixel, and the size of the light-emitting area of ​​the red micropixel is larger than the size of the light-emitting area of ​​the green micropixel.

[0147] The sum of the sizes of the luminescent regions of a micropixel, as observed through multiple openings, can be the same as or similar to the sizes of the luminescent regions of a first-type subpixel for multiple colors.

[0148] The size of the additional pixels, as observed through multiple openings, can vary for various colors.

[0149] The size of the additional pixel-defining member, as observed through the opening corresponding to the green micropixel, can be larger than the size of the pixel-defining member, as observed through the opening corresponding to the red micropixel.

[0150] The additional pixel-defined member, as observed through the plurality of openings, can have a strip shape.

[0151] The size of the pixel-defining member adjacent to the second type of sub-pixel and the size of the additional pixel-defining member can be different.

[0152] Micropixels for multiple colors can be driven by a single anode electrode.

[0153] The anode electrode may include an opening formed in at least a portion of a region that is perpendicular to and overlaps with the signal line.

[0154] The display device may further include a third type of sub-pixel having a viewing angle that is narrower than that of the first type of sub-pixel and wider than that of the second type of sub-pixel.

[0155] The width of the shielding member placed around the third type of sub-pixel can be smaller than the width of the shielding member placed around the second type of sub-pixel.

[0156] The sum of the sizes of the micropixels of the second type of subpixels for multiple colors can be greater than the size of the subpixels of the first type of subpixels for multiple colors.

[0157] The number of micropixels included in the second type of subpixel can be two or four.

[0158] As described above, a method for driving a display device including an organic light-emitting display (OLED) according to embodiments of the present disclosure may include: identifying an on state of the display; identifying the type of application to be executed when the display is requested to be turned on; and when the type of application is a first type, simultaneously turning on a first type sub-pixel and a second type sub-pixel to output a screen image on the display, wherein the first type sub-pixel irradiates light onto the display at a first viewing angle and the second type sub-pixel irradiates light at a second viewing angle smaller than the first viewing angle.

[0159] This method can further disable the first type of subpixel or display a specific grayscale value when the application type is the second type, and output the screen image on the display by enabling the second type of subpixel.

According to embodiments, communication module 1490 may include wireless communication module 1492 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 1494 (e.g., local area network (LAN) communication module or power line communication (PLC) module). One of these communication modules can communicate with an external electronic device via a first network 1498 (e.g., a short-range communication network such as Bluetooth, Wi-Fi Direct, or Infrared Data Association (IrDA)) or a second network 1499 (e.g., a long-range communication network such as a traditional cellular network, 5G network, next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 1492 can identify and verify the electronic device 1401 in the communication network (such as the first network 1498 or the second network 1499) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 1496.

[0178] Wireless communication module 1492 can support 5G networks following 4G networks and next-generation communication technologies (such as new radio (NR) access technologies). NR access technologies can support enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), or ultra-reliable low-latency communication (URLLC). Wireless communication module 1492 can support high-frequency bands (e.g., millimeter-wave bands) to achieve, for example, high data transmission rates. Wireless communication module 1492 can support various technologies used to ensure performance in high-frequency bands, such as, for example, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, or massive antennas. Wireless communication module 1492 can support various requirements specified in electronic device 1401, external electronic device (e.g., electronic device 1404), or network system (e.g., second network 1499). According to an embodiment, the wireless communication module 1492 may support peak data rates (e.g., 20 Gbps or greater) for implementing eMBB, lost coverage (e.g., 164 dB or less) for implementing mMTC, or U-plane latency (e.g., 0.5 ms or less for each of the downlink (DL) and uplink (UL), or 1 ms or less round trip) for implementing URLLC.

[0179] Antenna module 1497 can transmit or receive signals or power to or from the exterior of electronic device 1401 (e.g., external electronic device). According to an embodiment, antenna module 1497 may include an antenna comprising a radiating element formed of a conductive material or conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). According to an embodiment, antenna module 1497 may include multiple antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication scheme used in a communication network (such as a first network 1498 or a second network 1499) can be selected from the multiple antennas by, for example, communication module 1490 (e.g., wireless communication module 1492). Signals or power can then be transmitted or received between communication module 1490 and the external electronic device via the selected at least one antenna. According to an embodiment, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally incorporated into antenna module 1497.

[0180] According to various embodiments, antenna module 1497 can form a millimeter-wave antenna module. According to embodiments, the millimeter-wave antenna module may include a printed circuit board, a radio frequency integrated circuit (RFIC), and multiple antennas (e.g., an array antenna), wherein the RFIC is disposed on or adjacent to a first surface (e.g., a bottom surface) of the printed circuit board and is capable of supporting a specified high-frequency band (e.g., a millimeter-wave band), and the multiple antennas are disposed on or adjacent to a second surface (e.g., a top surface or a side surface) of the printed circuit board and are capable of transmitting or receiving signals in the specified high-frequency band.

[0181] At least some of the aforementioned components can be interconnected and communicate signals (e.g., commands or data) between them via an inter-peripheral communication scheme (e.g., bus, general purpose input / output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0182] According to an embodiment, commands or data can be sent or received between electronic device 1401 and external electronic device 1404 via server 1408 connected to a second network 1499. Each of electronic device 1402 or electronic device 1404 can be a device of the same type as electronic device 1401, or a device of a different type. According to an embodiment, all or some operations that would be performed on electronic device 1401 can be performed on one or more of external electronic devices 1402, external electronic devices 1404, or server 1408. For example, if electronic device 1401 is required to automatically perform a function or service, or is required to perform a function or service in response to a request from a user or another device, electronic device 1401 may request the one or more external electronic devices to perform at least a portion of the function or service, instead of running the function or service, or electronic device 1401 may request the one or more external electronic devices to perform at least a portion of the function or service in addition to running the function or service. Upon receiving the request, one or more external electronic devices may perform at least a portion of the requested function or service, or perform additional functions or services related to the request, and transmit the result of the execution to electronic device 1401. Electronic device 1401 may provide the result as at least a partial response to the request, with or without further processing. For this purpose, technologies such as cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing may be used. Electronic device 1401 may use, for example, distributed computing or mobile edge computing to provide ultra-low latency services. In another embodiment, external electronic device 1404 may include an Internet of Things (IoT) device. Server 1408 may be an intelligent server using machine learning and / or neural networks. According to an embodiment, external electronic device 1404 or server 1408 may be included in a second network 1499. Electronic device 1401 may be applied to intelligent services based on 5G communication technology or IoT-related technologies (e.g., smart homes, smart cities, smart cars, or healthcare).

[0183] Figure 15a This is a view illustrating an example of a display in which various types of subpixels are arranged according to an embodiment of the present disclosure. Figure 15b This illustrates an embodiment according to the present disclosure. Figure 15a A view of an example of a pixel structure of the type described in [the document].

[0184] Reference Figure 2a , Figure 2b and Figure 15aIn the display 160, modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e can be alternately configured. According to an embodiment, the configuration ratios of the modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e can be the same (e.g., 1:1:1) or different (e.g., 1:2:1, 1:2:2, or 2:1:2). The modified first-type pixels 160c can include those described above. Figure 2a or Figure 2b The modified first-type pixel 160c described herein is the same pixel as the first-type pixel 160c. For example, the modified first-type pixel 160c may include a structure in which first-type sub-pixels 161B, 161R, 161Ga, and 161Gb are disposed in areas where no shielding member is disposed. According to various embodiments, instead of the modified first-type pixel 160c, the above-described... Figure 2a The first type of pixel 160a is described in the diagram. Electrodes (e.g., anode electrodes) disposed in all pixels of the display 160 can have the same area or size, and their viewing angle can be adjusted by a shielding member. For example, pixel electrodes (e.g., anode electrodes) can have the same size and be repeatedly divided into four, and modified first type pixels 160c (or first type pixels), second type pixels 160b, and fourth type pixels 160e can be created by adjusting the width of the shielding member.

[0185] The second type of pixel 160b can be the same as the one above. Figure 2b The second type pixel 160b described herein is the same as the second type pixel 160b. For example, the second type pixel 160b may include second type sub-pixels 162B, 162R, 162Ga, and 162Gb, and the second type sub-pixels 162B, 162R, 162Ga, and 162Gb may include: a second type red sub-pixel 162R, corresponding to the first to fourth red micropixels 162R1, 162R2, 162R3, and 162R4; a second type blue sub-pixel 162B, corresponding to the first to fourth red micropixels 162B1, 162B2, 162B3, and 162B4; and a second type green sub-pixel 162R, corresponding to the first to fourth green micropixels 162G1, 162G2, 162G3, and 162G4. The second type pixel 160b may further include: a shielding member 162BM located between the second type sub-pixels 162B, 162R, 162Ga and 162Gb; a shielding member 162BMA located between micropixels; and a shielding member 162BM located at the perimeter of the second type sub-pixels 162B, 162R, 162Ga and 162Gb.

[0186] Apart from the shielding components, the fourth type pixel 160e may have the same pixel structure as the second type pixel 160b. For example, the fourth type sub-pixels 164B, 164R, 164Ga, and 164Gb may include: a fourth type red sub-pixel 164R, corresponding to the first to fourth red micropixels 164R1, 164R2, 164R3, and 164R4; a fourth type blue sub-pixel 164R, corresponding to the first to fourth blue micropixels 164B1, 164B2, 164B3, and 164B4; and fourth type green sub-pixels 164Ga and 164Gb, corresponding to the first to fourth green micropixels 164Ga1, 164Ga2, 164Ga3, 164Ga4 and 164Gb1, 164Gb2, 164Gb3, and 164Gb4. The fourth type red sub-pixel 164R can have the same structure as the second type red sub-pixel 162R, the fourth type blue sub-pixel 164B can have the same structure as the second type blue sub-pixel 162B, and the fourth type green sub-pixels 164Ga and 164Gb can have the same structure as the second type green sub-pixels 162Ga and 162Gb. Unlike the second type pixel 160b, in the fourth type pixel 160e, the size of the shielding member located between the fourth type sub-pixels 164B, 164R, 164Ga, and 164Gb can be different. The area (or width) of the shielding member located between the fourth type sub-pixels 164B, 164R, 164Ga, and 164Gb can be smaller than the area (or width) of the shielding member located between the second type pixels 162B, 162R, 162Ga, and 162Gb.

[0187] Reference Figure 3a and Figure 15b As shown in 1501, the first type sub-pixel (e.g., 161B, 161R, 161Ga, and 161Gb) included in the modified first type pixel 160c may include a substrate portion 160_1, a semiconductor layer 160_2, a first electrode 160_3 (e.g., an anode), a pixel defining member 160_4, an organic light-emitting layer 160_5, a second electrode 160_6 (e.g., a cathode), and an encapsulation layer 160_7. Additionally or optionally, a light-transmitting protective layer may be disposed on the encapsulation layer 160_7 of the first type sub-pixel.

[0188] Reference Figure 3b and Figure 15bAs shown in 1503, the second type sub-pixel (e.g., 162B, 162R, 162Ga, and 162Gb) included in the second type pixel 160b may include a substrate portion 162_1, a semiconductor layer 162_2, a first electrode 160_3 (e.g., an anode), a pixel defining member 162_4, an organic light-emitting layer 160_5, a second electrode 160_6 (e.g., a cathode), an encapsulation layer 160_7, a second shielding member 162BM, and a third shielding member 162BMA. Although not shown, an additional shielding member may be disposed at the upper end of the pixel defining member 160_4. The additional shielding member may be disposed between the pixel defining member 160_4 and different shielding members 162BM and 162BMA or 164BM and 164BMA. In this regard, the encapsulation layer 160_7 may include multiple layers, and additional shielding members may be disposed in at least one of the multiple layers of the encapsulation layer 160_7, and may be at least partially aligned with the pixel defining members 160_4 (or 162_4A and 160_4A) in an upward / downward direction (e.g., the direction in which the light of the display is irradiated or a direction perpendicular to the illustrated figures). The additional shielding members may be spaced apart from the pixel defining members 160_4, 160_4A, and 162_4A in a vertical direction, and may be configured to be spaced apart from another shielding member (e.g., 162BM and 162BMA or 164BM and 164BMA) by a specific distance in an upward / downward direction. Additionally or optionally, a light-transmitting protective layer may be disposed on the encapsulation layer 160_7 of the second type of sub-pixel. Therefore, the second shielding member 162BM and the third shielding member 162BMA may be disposed between the encapsulation layer 160_7 and the light-transmitting protective layer. The spacing between the second shielding member 162BM and the third shielding member 162BMA can be, for example, a first length W151. The second type of sub-pixel can be irradiated with light through a rectangular opening (an opening through which light passes, which may be filled with insulating material or at least a portion of a color filter), the length of which is the first length W151. The first length W151 can correspond to the length of the side portion of the emitting region of the second type of sub-pixel.

[0189] Reference Figure 15bAs shown in 1505, the fourth type sub-pixel (e.g., 164B, 164R, 164Ga, and 164Gb) included in the fourth type pixel 160e may include a substrate portion 160_1, a semiconductor layer 160_2, a first electrode 160_3 (e.g., an anode), a pixel defining member 160_4, an additional pixel defining member 160_4A, an organic light-emitting layer 160_5, a second electrode 160_6 (e.g., a cathode), an encapsulation layer 160_7, a fourth shielding member 164BM, and a fifth shielding member 164BMA. Although not shown, the additional shielding member may be disposed between the upper end of the pixel defining member 160_4 and the shielding member (e.g., 164BM and 164BMA). Additionally or optionally, a light-transmitting protective layer may be further disposed on the encapsulation layer 160_7 of the fourth type sub-pixel (e.g., 164B, 164R, 164Ga, and 164Gb). Therefore, the fourth shielding member 164BM and the fifth shielding member 164BMA can be disposed between the encapsulation layer 160_7 and the light-transmitting protective layer. The fourth shielding member 164BM can have a width smaller than that of the second shielding member 162BM. The fifth shielding member 164BMA can have a width smaller than that of the third shielding member 162BMA. The spacing between the fourth shielding member 164BM and the fifth shielding member 164BMA can, for example, be a second length W152. The fourth type of sub-pixel (e.g., 164B, 164R, 164Ga, and 164Gb) can be irradiated with light through a rectangular opening (e.g., an opening through which light passes, which can be filled with insulating material), one length of which is the second length W152. The side portion of the light-emitting region of the fourth type of sub-pixel (e.g., 164B, 164R, 164Ga, and 164Gb) can be a first length W151. As described above, compared to the openings of the second type of sub-pixels (e.g., 162B, 162R, 162Ga, and 162Gb), the fourth type of sub-pixels (e.g., 164B, 164R, 164Ga, and 164Gb) can irradiate light through a relatively large opening. Therefore, compared to the second type of sub-pixels 162B, 162R, 162Ga, and 162Gb, the fourth type of sub-pixels (e.g., 164B, 164R, 164Ga, and 164Gb) can exhibit relatively high luminance at specific angles when viewed from the side (e.g., between angles greater than 0 degrees and less than 90 degrees when the angle of viewing the display is 90 degrees perpendicular to the front surface of the display and 0 degrees parallel to the side surface of the display). The second shielding member 162BM and the third shielding member 162BM can have the same or similar dimensions as the pixel defining member 160_4a and the additional pixel defining member 162_4A.According to various embodiments, the fourth shielding member 164BM and the fifth shielding member 164BMA may have a width greater than that of the pixel defining member 160_4 and the additional pixel defining member 160_4A.

[0190] In a display 160 where modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e are distributed in a specific ratio, all modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e can be enabled and driven in normal mode, and some of the modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e can be enabled in privacy mode (or narrow viewing angle mode). For example, the electronic device 100 can support privacy mode by enabling the remaining pixels of the modified first-type pixels 160c, second-type pixels 160b, and fourth-type pixels 160e, excluding the modified first-type pixel 160c. The electronic device 100 can support privacy mode by disabling some first-type pixels 160c and fourth-type pixels 160e among the pixels set in the display 160 and enabling the remaining fourth-type pixels 160e and second-type pixels 160b. The electronic device 100 can change the on / off state of some areas of the fourth-type pixels according to a specific time period or the type of application being executed. For example, when privacy mode is supported, electronic device 100 can perform control such that the first region of fourth type pixel 160e is turned on and the second region of fourth type pixel 160e is turned off, while the off state of second type pixel 160b is maintained. Electronic device 100 can control, according to user settings or application type, such that only fourth type pixel 160e is turned on and modified first type pixel 160c and second type pixel 160b are turned off. Optionally, electronic device 100 can control, according to user settings or application type, such that only second type pixel 160b is turned on and modified first type pixel 160c and fourth type pixel 160e are turned off. Through the above control, compared to privacy mode using only second type pixel 160b, the electronic device 100 of this disclosure can help improve relatively high brightness performance and lifespan. Furthermore, the electronic device 100 of this disclosure can improve content visibility when necessary by increasing brightness performance, and simultaneously improve viewing angle control performance by adaptively adjusting viewing angle and brightness according to application type or user settings for content with relatively high security or content that the user does not wish to display to third parties. The electronic device 100 can support improved control of viewing angle and visibility by adaptively differentiating the types of pixels that are turned on and off according to time settings (e.g., day or night) or lighting intensity settings.

[0191] Figure 16This is a view showing the luminance characteristics of a pixel structure from a perspective according to an embodiment of the present disclosure.

[0192] Reference Figure 2a , Figure 2b and Figure 16 Curve 1601 shows the brightness characteristics of display 160 in normal mode, which includes the above-mentioned... Figure 2a and Figure 2b The first type pixel 160a or modified first type pixel 160c and second type pixel 160b are described in the figures. In the figures, the horizontal axis relates to the angle of viewing the display 160; 0° can mean a direction perpendicular to the front surface of the display 160, and 90° can mean a direction parallel to the front surface of the display 160. When viewing the front surface of the display 160 perpendicularly, or when viewing the display 160 parallel to the side surface relative to the front surface, a luminance of 0.0 can be observed when both the first type pixel 160c and the second type pixel 160b are turned on.

[0193] Curve 1602 shows when execution is based on Figure 2a or Figure 2b The luminance characteristics are described in the privacy mode with only the second type of pixel 160b enabled. When the privacy mode is executed with the first type of pixel 160a disabled and the second type of pixel 160b enabled in the display 160 at a 50:50 ratio, a luminance characteristic of 0.5 can be observed. As shown, in the privacy mode, as the luminance decreases rapidly from 30 degrees or more in the direction perpendicular to the front surface of the display, it becomes difficult to observe the screen of the display 160 from the side, thus narrowing the lateral field of view and preventing observation of the screen of the display 160.

[0194] Curve 1603 is shown in which it is set Figure 15a The diagram shows a view of the brightness characteristics of the display 160 in a normal mode environment, comprising the first type of pixels 160a, the second type of pixels 160b, and the fourth type of pixels 160e. For example, curve 1603 shows the brightness characteristics of the display 160 with all three types of pixels 160a, 160b, and 160e turned on. It can be seen that, compared to curve 1601, the brightness characteristics are relatively improved as they are laterally moved about a direction perpendicular to the front surface of the display 160.

[0195] Curve 1604 illustrates the settings therein. Figure 15aThe image shows a view of the brightness characteristics in privacy mode of a display 160 with first-type pixels 160a, second-type pixels 160b, and fourth-type pixels 160e as described. It can be seen that when the first-type pixel 160a is turned off and the second-type pixels 160b and fourth-type pixels 160e are turned on in a display in which the first-type pixels 160a, second-type pixels 160b, and fourth-type pixels 160e are set, a relatively improved brightness characteristic is displayed in the lateral direction at an angle of 10 degrees or greater relative to the front surface facing the display 160, compared to curve 1602.

[0196] Curve 1605 illustrates the settings therein. Figure 15a This is a view of the luminance characteristics in a modified privacy mode of the display 160, comprising the first type pixel 160a, the second type pixel 160b, and the fourth type pixel 160e described herein. The modified normal mode shows the luminance characteristics for the angle between the vertical and lateral directions facing the front surface of the display 160 when the first type pixel 160a and the second type pixel 160b are on and the fourth type pixel 160e is off. As shown, curve 1605 shows improved luminance characteristics between 0 and 65 degrees compared to curve 1601, while exhibiting relatively low luminance characteristics compared to curve 1603. As described above, by controlling various pixels, including... Figure 15a The display 160, with its first type of pixels 160a, second type of pixels 160b, and fourth type of pixels 160e, can be configured to provide relatively superior brightness characteristics or to use a relatively narrow viewing angle, depending on user settings in normal mode, privacy mode, and modified normal mode, as needed. The display 160 described above can support improvements in lifetime, lateral brightness, visibility, and brightness and lifetime compensation in privacy mode.

[0197] Figure 17 This is a view illustrating an example of the pixel structure of a display associated with parasitic capacitance according to an embodiment of the present disclosure.

[0198] Reference Figure 17 As shown above Figure 2aThe described display 160 may include a first type pixel 160a and a second type pixel 160b. The anode electrode disposed in a pixel of the display 160 may overlap with a signal line 1710 (e.g., a data line) associated with the driving of the pixel in an upward / downward direction. Therefore, undesirable parasitic capacitance may occur between the signal line and the electrode (e.g., the anode) disposed in the pixel. An opening may be formed at at least a portion of the electrode included in the second type pixel 160b to reduce the aforementioned parasitic capacitance. A second type blue sub-pixel 162B of the second type pixel 160b may correspond to a first type blue sub-pixel 161B of the first type pixel 160a in terms of screen display implementation. The second type blue sub-pixel 162B may include four micropixels, and the second type blue sub-pixel 162B may have the same area as or be larger than the first type blue sub-pixel 161B by a specific size. Considering the area of ​​the shielding member between the four micropixels, the second type blue subpixel electrode 162BP used for light emission in the pixel structure of the second type blue subpixel 162B can have a larger area than the electrode of the first type blue subpixel 161B.

[0199] The first opening 162BO can be formed on one side of the second type blue sub-pixel electrode 162BP to reduce the area overlapping with the signal line 1710. The first opening 162BO can be filled, for example, with insulating material used in the manufacturing process of the display 160. A second opening 162RO can also be formed on one side of the second type red sub-pixel electrode 162RP. The second opening 162RO can also be filled, for example, with insulating material used in the manufacturing process of the display 160. The third opening 162GaO and the fourth opening 162GbO can be formed on one side of the second type green sub-pixel electrodes 162GaP and 162GbP. The third opening 162GaO and the fourth opening 162GbO can also be filled, for example, with insulating material used in the manufacturing process of the display 160. The first opening 162BO, the second opening 162RO, the third opening 162GaO, and the fourth opening 162GbO can be formed in an area that does not overlap with the light-emitting area of ​​the corresponding sub-pixel. Although the first opening 162BO and the second opening 162RO are shown to have a first shape, and the third opening 162GaO and the fourth opening 162GbO have a second shape different from the first shape, this disclosure is not limited thereto. The first to fourth openings may have the same shape or may have different shapes. The structure in which openings are formed in the pixel electrodes described above can also be applied in the same or similar manner to other pixel structures described above, such as third type pixel 160d and fourth type pixel 160e. For example, openings may be formed in at least a portion of the space between micropixels and may include segments in which signal lines overlap each other.

[0200] Figure 18This is a view illustrating an example of the pixel structure of a display associated with parasitic capacitance according to an embodiment of the present disclosure.

[0201] Reference Figure 18 As shown in 1801, the second type blue sub-pixel 162B may include fourth blue micropixels 162B1, 162B2, 162B3, and 162B4. The second type blue sub-pixel 162B may include a second type blue sub-pixel electrode 162BP associated with the driving of the blue micropixels 162B1, 162B2, 162B3, and 162B4. As described above, at least some of the signal lines 1710 (e.g., data lines) may be disposed below the second type blue sub-pixel electrode 162BP. A fifth opening 162BOE1 may be formed within the second type blue sub-pixel electrode 162BP. The fifth opening 162BOE1 may, for example, include at least a portion of the region between the first blue micropixel 162B1 and the fourth blue micropixel 162B4, at least a portion of the region between the second blue micropixel 162B2 and the fourth blue micropixel 162B4, and at least a portion of the region between the first blue micropixel 162B1 and the second blue micropixel 162B2. Insulating material can be filled in the fifth opening 162BOE1.

[0218] Reference Figure 20 The display 160 can be operated such that multiple sub-pixels are set for multiple colors in a single scan line (or a single gate line). For example, a first scan line Scan(n-1) can supply scan signals to pixels in which second-type pixels 160b and first-type pixels 160a are repeatedly set, the second-type pixels 160b including second-type blue sub-pixels 162B, second-type red sub-pixels 162R, second-type first green sub-pixels 162Ga, and second-type second green sub-pixels 162Ga, and the first-type pixels 160a including first-type blue sub-pixels 161B, first-type red sub-pixels 161R, first-type first green sub-pixels 161Ga, and first-type second green sub-pixels 161Gb.

[0221] Figures 19a to 20The display 160 described above can be configured such that different types of pixels set for the horizontal axis (or scan line or gate line) operate based on the same scan signal. In the display 160, because RG or BG pixels are repeatedly set for different types in a pentile structure where pixels are repeatedly set according to specific rules, color shift is mitigated, and the display 160 can be driven in a simpler way.
