[0041] It should be noted that these figures are intended to illustrate the general characteristics of methods, structures and / or materials used in certain exemplary embodiments and are intended to supplement the written description provided below. However, these drawings are not to scale and may not accurately reflect the precise structure or performance characteristics of any given embodiment and should not be interpreted as defining or limiting the range of values or properties encompassed by the exemplary embodiments. For example, the relative thicknesses of molecules, layers, regions and / or structural elements may be reduced or exaggerated for clarity. The use of similar or identical reference numerals in different figures is intended to indicate the presence of similar or identical elements or features. DETAILED DESCRIPTION
[0042] In the following description, for the purpose of explanation, many specific details are set forth in order to provide a thorough understanding of various embodiments or implementations of the present invention. As used herein, "embodiment" and "implementation" are interchangeable words, which are non-limiting examples of one or more devices or methods using the inventive concepts disclosed herein. However, it is apparent that various embodiments can be practiced without these specific details or with one or more equivalent arrangements. In other cases, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily blurring the various embodiments. In addition, various embodiments can be different, but do not have to be exclusive. For example, without departing from the present invention, the specific shape, configuration and characteristics of the embodiment can be used or implemented in another embodiment.
[0043] Unless otherwise specified, the embodiments described should be understood as providing exemplary features of varying details of some ways in which the inventive concept may be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects of the various embodiments (hereinafter, individually or collectively referred to as "elements") may be combined, separated, interchanged and / or rearranged in other ways without departing from the inventive concept.
[0044] The use of cross hatching and / or shading in the drawings is generally provided to clarify the boundaries between adjacent elements. Therefore, unless specified, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for a particular material, material properties, size, ratio, commonality between the elements shown and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements may be exaggerated for the purpose of clarity and / or description. When the embodiments can be implemented differently, the specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described sequence. In addition, the same reference numerals represent the same elements.
[0045] When an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it may be directly on, directly connected to, or directly coupled to the other element or layer, or there may be intervening elements or layers. However, when an element or layer is referred to as being "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, and / or a fluid connection with or without intervening elements. In addition, the DR1 axis, the DR2 axis, and the DR3 axis are not limited to the three axes of a rectangular coordinate system, such as the x-axis, the y-axis, and the z-axis, and may be interpreted in a broader sense. For example, the DR1 axis, the DR2 axis, and the DR3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as, for example, XYZ, XYY, YZ, and ZZ. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.
[0046] Although the terms "first," "second," etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. Thus, the first element discussed below may be referred to as the second element without departing from the teachings of the present disclosure.
[0047] For descriptive purposes, spatially relative terms such as "below," "beneath," "under," "down," "above," "up," "above," "higher," "side" (e.g., as in "sidewall"), etc., may be used herein and thereby describe the relationship of one element to another element(s) as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, elements described as "below" or "beneath" other elements or features will then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both above and below orientations. Additionally, the device may be otherwise oriented (e.g., rotated 90 degrees or in other orientations), and therefore, the spatially relative descriptors used herein should be interpreted accordingly.
[0048] The terms used herein are for the purpose of describing specific embodiments and are not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. In addition, when used in this specification, the terms "comprises," "comprising," "includes," and / or "including" specify the presence of the features, wholes, steps, operations, elements, components, and / or groups thereof set forth, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or groups thereof. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximate terms and not as terms of degree, and, therefore, are used to allow for inherent deviations in measurements, calculations, and / or provided values that will be recognized by one of ordinary skill in the art.
[0049] Various embodiments are described herein with reference to cross-sectional views and / or exploded views that are schematic diagrams of idealized embodiments and / or intermediate structures. Therefore, variations in the shapes in the figures, for example, due to manufacturing techniques and / or tolerances, should be expected. Therefore, the embodiments disclosed herein should not necessarily be interpreted as being limited to the specific illustrated regional shapes, but should include deviations in shapes, for example, due to manufacturing. In this way, the regions shown in the drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device and are therefore not necessarily intended to be limiting.
[0050] As is customary in the art, some embodiments are described and illustrated in the figures with respect to functional blocks, units, and / or modules. Those skilled in the art will appreciate that these blocks, units, and / or modules are physically implemented using electrical circuits (or optical circuits) such as logic circuits, discrete components, microprocessors, hard-wired circuits, memory elements, wiring connectors, and the like, which can be formed using semiconductor-based or other manufacturing technologies. Where blocks, units, and / or modules are implemented using microprocessors or other similar hardware, they can be programmed and controlled using software (e.g., microcode) to perform the various functions discussed herein, and can optionally be driven by firmware and / or software. It is also contemplated that each block, unit, and / or module can be implemented using dedicated hardware, or as a combination of dedicated hardware for performing some functions and a processor (e.g., one or more programmed microprocessors and associated circuitry) for performing other functions. Furthermore, without departing from the scope of the inventive concept, each block, unit, and / or module in some embodiments can be physically separated into two or more interacting and discrete blocks, units, and / or modules. Furthermore, without departing from the scope of the inventive concept, blocks, units and / or modules in some embodiments may be physically combined into more complex blocks, units and / or modules.
[0051] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

Figure 2 is an exploded perspective view illustrating an electronic device according to an embodiment of the present inventive concept. Figure 3 is a block diagram illustrating an electronic device according to an embodiment of the inventive concept.
[0053] Reference Figures 1 to 3 When the electronic device ED is activated by an electrical signal applied thereto, the electronic device ED can display an image. The electronic device ED may be a tablet computer, a laptop computer, a computer, a television, etc. In this embodiment, a smartphone will be described as an example of the electronic device ED.
[0054] The electronic device ED may include a display surface FS that is parallel to each of the first direction DR1 and the second direction DR2 and is used to display an image IM in the third direction DR3. The display surface FS that displays the image IM may correspond to the front surface of the electronic device ED and the front surface of the window 100. Hereinafter, the display surface or front surface of the electronic device ED and the front surface of the window 100 may be referred to using the same reference numerals. The image IM may be a video image or a still image. Figure 1 A clock widget and a plurality of application icons are shown as examples of the image IM.
[0055] In this embodiment, the front surface or top surface and the rear surface or bottom surface of each element may be defined based on the display direction of the image IM. The front surface and the rear surface may be opposite to each other in the third direction DR3, and the normal direction of each of the front surface and the rear surface may be parallel to the third direction DR3. Meanwhile, the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 may be relative concepts and, in embodiments, may be changed to indicate other directions.
[0056] The electronic device ED may include a window 100, a display module 200, a driving circuit portion 300, a housing 400, and a camera module 500. In this embodiment, the window 100 and the housing 400 may be combined with each other to define an appearance of the electronic device ED.
[0057] Window 100 may include an optically transparent insulating material. For example, window 100 may be formed of or include at least one of glass and plastic materials. Window 100 may have a multi-layer structure or a single-layer structure. For example, window 100 may include multiple plastic films bonded together by an adhesive material, or may include a glass substrate and a plastic film bonded together by an adhesive material.
[0058] When viewed in a plan view, the display surface FS may include a transmissive area TA and a bezel area BZA. In this specification, the expression "when viewed in a plan view" may be used to describe the shape of an object viewed in the third direction DR3.
[0059] The transmissive area TA may be an optically transparent area. The frame area BZA may have a relatively low light transmittance compared to the transmissive area TA. The frame area BZA may define the shape of the transmissive area TA. The frame area BZA may be adjacent to the transmissive area TA and may surround the transmissive area TA.
[0060] The bezel area BZA may have a predetermined color. The bezel area BZA may cover the non-active area NAA of the display module 200 and prevent the non-active area NAA from being recognized by the user. However, the present invention is not limited to this example, and in an embodiment, the bezel area BZA may be omitted from the window 100.
[0061] In an embodiment, the first module area MA1 may be an area overlapping with the camera module 500. The electronic device ED may receive an external signal required by the camera module 500 through the first module area MA1, or provide a signal output from the camera module 500 to the outside. For example, the camera module 500 may sense the approach of the user's finger through the first module area MA1. According to an embodiment of the present invention, the first module area MA1 may be defined to overlap with the transmission area TA. Therefore, compared with the case where the first module area MA1 is set in the frame area BZA, the area of the frame area BZA may reduce the area of the first module area MA1. The second module area MA2 may correspond to an area set to surround the first module area MA1. In an embodiment, the second module area MA2 may include a light blocking area. For example, the second module area MA2 may be an area overlapping with the light blocking area BA of the display panel 210 (for example, see Figure 8B ). The first module area MA1 may overlap the first transmission area HA1, and the second module area MA2 may overlap the second transmission area HA2. The second module area MA2 may have a transmittance lower than that of the first module area MA1.
[0062] Figure 1 and Figure 2 An example is shown in which the first module area MA1 and the second module area MA2 are disposed in the upper right portion of the transmission area TA, but in some embodiments, the first module area MA1 and the second module area MA2 may be defined in various areas (e.g., in the upper left portion, the center portion, the lower left portion, or the lower right portion of the transmission area TA).
[0063] like Figure 2 As shown in , the display module 200 may be disposed below the window 100. In this specification, the preposition "below" may be used to indicate a direction opposite to the propagation direction of image light emitted from the display module 200. The display module 200 may be configured to display an image IM and sense an external input TC from a user's finger, hand, or other body part. The display module 200 may include a front surface IS having an active area AA and a non-active area NAA. The active area AA may be an area activated according to an electrical signal.
[0064] In this embodiment, the active area AA can be used to display an image IM and sense an external input TC. The transmissive area TA may overlap at least with the active area AA. For example, the transmissive area TA may overlap with the entire surface of the active area AA or at least a portion thereof. Thus, a user can view an image IM through the transmissive area TA, or can input an external input TC through the transmissive area TA.
[0065] The non-active area NAA may be an area covered by the border area BZA. The non-active area NAA may be adjacent to the active area AA. The non-active area NAA may surround the active area AA. Driving circuits, driving lines, etc. for operating the active area AA may be disposed in the non-active area NAA.
[0066] In the present embodiment, the display module 200 is shown as having a flat shape in the active area AA and the non-active area NAA, but the present invention is not limited to this example. For example, the display module 200 may be partially curved in the non-active area NAA. Here, the display module 200 in the non-active area NAA may be curved in such a way that a portion of it faces the rear surface of the electronic device ED, and in this case, the area of the border area BZA in the front surface FS of the electronic device ED may be reduced. In addition, in the active area AA, the display module 200 may be configured to have a partially curved shape. In some embodiments, the non-active area NAA may be omitted from the display module 200.
[0067] The display module 200 may include a display panel 210 and an input sensing portion 220 .
[0068] The display panel 210 may be an element that substantially generates an image IM. The image IM generated by the display panel 210 may be displayed on the front surface IS of the display module 200 and may be provided to the outside or a user through the transmissive area TA.
[0069] The input sensing portion 220 can sense external input TC applied from the outside. The external input TC can correspond to a user's finger. For example, the input sensing portion 220 can sense the external input TC provided through the window 100. The external input TC can be a user's input. The user's input can include various types of external inputs, such as a part of the user's body, light, heat, pressure, or a pen. In this embodiment, the external input TC is shown as a touch event, which is generated by the user's hand and transmitted through the display surface FS of the electronic device ED, but the present invention is not limited to this example. For example, as described above, the external input TC can be provided in various forms, and in some embodiments, depending on the structure of the electronic device ED, the external input TC can be input through the side surface or rear surface of the electronic device ED. In an embodiment, the input sensing portion 220 can sense the external input TC applied to the second module area MA2.
[0070] The driving circuit part 300 may be electrically connected to the display panel 210 and the input sensing part 220. The driving circuit part 300 may include a main circuit board MB, a first flexible film CF1, a second flexible film CF2, and a driving chip DC.
[0071] The first flexible film CF1 may be electrically connected to the display panel 210. The first flexible film CF1 may connect the display panel 210 to the main circuit board MB. The first flexible film CF1 may be coupled to a pad (hereinafter, a display pad) provided in the non-active area NAA of the display panel 210. The first flexible film CF1 may provide an electrical signal for operating the display panel 210 to the display panel 210. The electrical signal may be generated by the first flexible film CF1 or the main circuit board MB.
[0072] The second flexible film CF2 may be electrically connected to the input sensing portion 220. The second flexible film CF2 may connect the input sensing portion 220 to the main circuit board MB. The second flexible film CF2 may be coupled to pads (hereinafter, sensing pads) of the input sensing portion 220 disposed in the non-active area NAA. The second flexible film CF2 may provide the input sensing portion 220 with an electrical signal for operating the input sensing portion 220. The electrical signal may be generated by the second flexible film CF2 or by the main circuit board MB.
[0073] The main circuit board MB may include various driving circuits for driving the display module 200 or a connector for supplying power, etc. The first flexible film CF1 and the second flexible film CF2 may be coupled to the main circuit board MB. According to this embodiment, the display module 200 can be easily controlled by a single main circuit board MB. However, the present inventive concept is not limited to this example or specific embodiment, and in the display module 200 according to the embodiment, the display panel 210 and the input sensing portion 220 may be connected to different main circuit boards, one of the first flexible film CF1 and the second flexible film CF2 may not be connected to the main circuit board MB, and the driver chip DC may be electrically connected to the display panel 210 to provide operating signals to the pixels of the display panel 210.
[0074] In embodiments, the area of the display module 200 corresponding to the first module area MA1 may have a higher transmittance than the active area AA that does not overlap with the first module area MA1. For example, at least a portion of the elements constituting the display panel 210 and the input sensing portion 220 may be removed. Therefore, the camera module 500, which is positioned to overlap with the first module area MA1, can easily transmit or receive signals through the first module area MA1.
[0075] Reference Figure 2, a high transmittance area may be defined in an area of the display module 200 corresponding to the first module area MA1. The high transmittance area may correspond to the first transmittance area HA1. In an embodiment, the first transmittance area HA1 may be defined in the active area AA so as to penetrate the display module 200. Since the first transmittance area HA1 is defined in the active area AA, the first module area MA1 may be disposed in the transmittance area TA. The second transmittance area HA2 may correspond to an area disposed so as to surround the first transmittance area HA1. The second transmittance area HA2 may have a transmittance lower than that of the first transmittance area HA1. A portion of the second transmittance area HA2 may overlap with the light blocking area BA (for example, see Figure 8B )overlapping.
[0076] When viewed in plan, the camera module 500 may overlap the first transmission area HA1 and the first module area MA1. The camera module 500 may be disposed below the display module 200, and at least a portion of the camera module 500 may be disposed within the first transmission area HA1. The camera module 500 may receive an external input TC transmitted through the first transmission area HA1, or may provide an output to the outside through the first transmission area HA1.
[0077] The housing 400 may be coupled to the window 100. The housing 400 may be coupled to the window 100 to provide an inner space. The display module 200 and the camera module 500 may be accommodated in the inner space.
[0078] The housing 400 may be formed of or include a material having relatively high rigidity or strength. For example, the housing 400 may include at least one of glass, plastic, and metal, or may include multiple frames and / or plates made of glass, plastic, or metal. The housing 400 may stably protect the components of the electronic device ED disposed within the interior space from external impact.
[0079] Reference Figure 3 The electronic device ED may include a display module 200, a power module PM, a first electronic module EM1, and a second electronic module EM2. The display module 200, the power module PM, the first electronic module EM1, and the second electronic module EM2 may be electrically connected to each other.
[0080] The power module PM may provide power to the electronic device ED. In an embodiment, the power module PM may include a conventional battery module.
[0081] The first electronic module EM1 and the second electronic module EM2 may include various functional modules for operating the electronic device ED.
[0082] The first electronic module EM1 may be directly mounted on a motherboard electrically connected to the display module 200.

[0093] Reference Figure 4 , the display panel 210 may include a base layer BL, a plurality of pixels PX, a plurality of signal lines GL, DL, and PL, and a plurality of display pads PDD.
[0094] The active area AA of the display panel 210 may include an area for displaying an image, and the non-active area NAA may include an area in which a driving circuit, a driving line, etc. are disposed. Figure 4 2 shows an active area AA and a non-active area NAA of the display panel 210. The pixels PX may be disposed in the active area AA.
[0095] The base layer BL may be a silicon substrate, a plastic substrate, a glass substrate, an insulating film, or a stack including a plurality of insulating layers.
[0096] The active area AA may include a signal transmission area STA, a peripheral display area SA, and a main display area NSA. The signal transmission area STA may correspond to an area of the active area AA that is not used to display an image. The signal transmission area STA may correspond to an area overlapping with the camera module 500. The signal transmission area STA may correspond to a high-transmittance area. In an embodiment, an opening may be defined in the signal transmission area STA. The peripheral display area SA may be adjacent to the signal transmission area STA. The main display area NSA may be an area that is farther from the signal transmission area STA than the peripheral display area SA and is disposed to surround the peripheral display area SA.

[0099] The pixels PX for generating an image may not be provided on the signal transmission area STA of the base layer BL. Therefore, the signal transmission area STA may be defined as a high-transmittance area or a non-display area in the active area AA. The pixels PX may be provided on the peripheral display area SA and the main display area NSA of the base layer BL. Therefore, the peripheral display area SA and the main display area NSA may be defined as a low-transmittance area or a display area in the active area AA.
[0100] The signal lines GL, DL, and PL may be connected to the pixels PX and may be used to transmit electrical signals to the pixels PX. Figure 4 As exemplarily shown in FIG, the signal lines in the display panel 210 may include scan lines GL, data lines DL, and power lines PL. However, the present invention is not limited to this example or specific embodiment, and the signal lines GL, DL, and PL may further include at least one of an initialization voltage line and an emission control line.
[0101] In this embodiment, an exemplary circuit diagram of one of the pixels PX is shown in an enlarged manner. The pixel PX may include a first transistor TR1, a capacitor CP, a second transistor TR2, and a light-emitting device OLED. The first transistor TR1 may be a switching device that controls the on / off state of the pixel PX.

[0103] The second transistor TR2 can be connected to the first transistor TR1, the capacitor CP, and the light-emitting device OLED. The second transistor TR2 can control the driving current flowing through the light-emitting device OLED based on the amount of charge stored in the capacitor CP. The on-time of the second transistor TR2 can be determined according to the amount of charge stored in the capacitor CP. During the on-time of the second transistor TR2, the second transistor TR2 can provide the first power signal transmitted via the power line PL to the light-emitting device OLED.
[0104] The light emitting device OLED may generate light or control the amount of light according to an electrical signal. For example, the light emitting device OLED may include an organic light emitting device or a quantum dot light emitting device.
[0105] The light-emitting device OLED may be connected to the power supply terminal VSS and may receive a power signal (hereinafter, a second power signal) different from the first power signal provided through the power line PL. The voltage difference between the power signal provided by the second transistor TR2 and the second power signal may determine the amount of driving current flowing through the light-emitting device OLED, and in this case, the intensity of light generated by the light-emitting device OLED may be determined by the amount of driving current. However, the present inventive concept is not limited to this example or specific embodiment, and in embodiments, the pixel PX may include electronic devices arranged in various structures or arrangements.

In an embodiment, in addition to the first pad D1 and the second pad D2, the display pad PDD may further include other pads for receiving other electrical signals, but the present inventive concept is not limited to this example or specific embodiment.
[0107] Figure 5 is a plan view illustrating a plurality of first and second pixels according to an embodiment of the inventive concept. Figure 5 It shows Figure 4 An enlarged plan view of area XX'.
[0108] Reference Figure 5The display panel 210 may include a plurality of first pixels disposed in the unit area UA1 of the main display area NSA and a plurality of second pixels disposed in the unit area UA2 of the peripheral display area SA-1. Figure 5 An example is shown in which the peripheral display area SA-1 has twelve unit areas UA2 adjacent to the signal transmission area STA, but the present invention is not limited to this example. For example, the peripheral display area SA-1 may be configured to have twelve or more unit areas UA2 that are disposed closer to the signal transmission area STA than the main display area NSA.
[0109] As long as the peripheral display area SA-1 can be set adjacent to the signal transmission area STA, the peripheral display area SA-1 may not have a shape surrounding the signal transmission area STA. The present invention is not limited to a specific shape of the peripheral display area SA-1 (e.g., a square), and the shape of the peripheral display area SA-1 may be changed differently as long as it includes a sufficient number of second pixels to implement the present invention. For example, the peripheral display area SA-1 may be a dodecagonal area. In an embodiment, the first pixel may refer to a pixel included in the unit area UA1 of the main display area NSA, and the second pixel may refer to a pixel included in the unit area UA2 of the peripheral display area SA-1. Here, the pixel PX may include a first color pixel PX-G (PX-G1 and / or PX-G2), a second color pixel PX-R, and a third color pixel PX-B, and may be used as a general term to represent all of them. The first color pixel PX-G may emit green light, the second color pixel PX-R may emit red light, and the third color pixel PX-B may emit blue light.
[0110] In an embodiment, the first pixel may include a first color pixel PX-G, a second color pixel PX-R, and a third color pixel PX-B. The second pixel may include a first color pixel PX-G and a second color pixel PX-R.
[0111] All of the first and second pixels may include a plurality of first color pixels PX-G1 and second color pixels PX-R.
[0112] In an embodiment, the emission area of green light in the unit area UA1 of the first pixel may be different from the emission area of green light in the unit area UA2 of the second pixel. For example, the emission area of green light in the unit area UA1 of the first pixel may be smaller than the emission area of green light in the unit area UA2 of the second pixel. The number of first color pixels PX-G in the second pixel may be greater than the number of first color pixels PX-G in the first pixel.
[0113] In an embodiment, a first pixel in unit area UA1 may include two first color pixels PX-G1, one second color pixel PX-R, and one third color pixel PX-B, and a second pixel in unit area UA2 may include only at least two first color pixels PX-G1 and PX-G2 and at least one second color pixel PX-R. In an embodiment, the second pixel may further include a third color pixel PX-B. In this case, the emission area of the third color pixel PX-B in the second pixel may be smaller than the emission area of the third color pixel PX-B in the first pixel.
[0114] In an embodiment, a plurality of unit areas UA2 may be provided in the peripheral display area SA-1. In this case, the second pixel may include a third color pixel PX-B provided in some of the unit areas UA2. The number of unit areas UA2 having the third color pixel PX-B may be less than half the number of unit areas UA2 in the peripheral display area SA-1. The second pixel in the unit area UA2 having the third color pixel PX-B may include two first color pixels PX-G, one second color pixel PX-R, and one third color pixel PX-B. In this case, similar to the first pixel, the second pixel in some unit areas UA2 of the peripheral display area SA-1 may include the first color pixel PX-G, the second color pixel PX-R, and the third color pixel PX-B, but the emission area of the green light emitted from the first color pixel PX-G in the unit area UA2 of the second pixel may still be larger than the emission area of the green light emitted from the first color pixel PX-G in the unit area UA1 of the first pixel.
[0115] The first pixel and the second pixel may include four pixels in each unit area. The four pixels may include two pixels having a first area, one pixel having a second area, and one pixel having a third area, wherein the first area may be smaller than the second area and the second area may be smaller than the third area. In an embodiment, in the case of the first pixel, the pixel having the first area may be a first color pixel PX-G that emits green light, the pixel having the second area may be a second color pixel PX-R that emits red light, and the pixel having the third area may be a third color pixel PX-B that emits blue light. In the case of the second pixel, the pixel having the first area and the pixel having the third area may be the first color pixel PX-G that emits green light, and the pixel having the second area may be the second color pixel PX-R that emits red light.
[0116] Figure 6A and Figure 6B is shown along Figure 2 A sectional view of a section taken along line II'.
[0117] In detail, Figure 6A is a cross-sectional view illustrating a rigid type display module 200 according to an embodiment of the present inventive concept, and Figure 6B is a cross-sectional view illustrating a flexible display module 200 - 1 according to an embodiment of the present inventive concept. In the case of the flexible display module 200 - 1 , the thin encapsulation layer TFE may be described separately, and the remaining elements will be described together with the rigid display module 200 .
[0118] like Figure 6A As shown in , the rigid type display panel 210 may include a base layer BL, a circuit device layer DP-CL disposed on the base layer BL, and a display device layer DP-OLED and an encapsulation substrate EC disposed on the circuit device layer DP-CL.

For example, the encapsulation substrate EC may include a glass substrate. Furthermore, the encapsulation substrate EC may include a substrate having a substantially uniform refractive index within the visible light wavelength range. The stacked structure including the base layer BL to the display device layer DP-OLED may be defined as a lower display substrate. A gap GP may be formed between the display device layer DP-OLED and the encapsulation substrate EC. The gap GP may be filled with air or an inert gas (hereinafter, external gas).
[0120] like Figure 6B As shown in , the flexible display panel 210 - 1 may include a base layer BL, a circuit device layer DP-CL disposed on the base layer BL, and a display device layer DP-OLED and a thin encapsulation layer TFE disposed on the circuit device layer DP-CL.
[0121] The thin encapsulation layer TFE may seal or encapsulate the display device layer DP-OLED. The thin encapsulation layer TFE may include at least one insulating layer. In an embodiment, the thin encapsulation layer TFE may include at least one inorganic layer (hereinafter, inorganic encapsulation layer). In an embodiment, the thin encapsulation layer TFE may include at least one organic layer (hereinafter, organic encapsulation layer) and at least one inorganic encapsulation layer. The inorganic encapsulation layer may protect the display device layer DP-OLED from moisture or oxygen, and the organic encapsulation layer may protect the display device layer DP-OLED from contaminating materials such as dust particles. The inorganic encapsulation layer may include a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer, but the present invention is not limited to these examples. The organic encapsulation layer may include an acryl-based organic layer, but the present invention is not limited to this example.
[0122] The flexible display module 200-1 may include a first transmission area HA1 and a second transmission area HA2, which are defined within an active area AA and correspond to a high-transmittance region and a low-transmittance region, respectively. The first transmission area HA1 of the flexible display module 200-1 may be open-type and may include an opening defined therein, unlike the first transmission area HA1 of the closed, rigid display module 200. The first transmission area HA1 may overlap with the signal transmission area STA of the flexible display panel 210-1. The second transmission area HA2 may overlap with the peripheral display area SA of the flexible display panel 210-1. In addition to the first transmission area HA1 and the second transmission area HA2, the active area AA may overlap with the main display area NSA of the flexible display panel 210-1.
[0123] Although not in Figure 6A and Figure 6B , but the display device layer DP-OLED may include a plurality of pixels. The first pixel may be provided in an area of the display device layer DP-OLED corresponding to the main display area NSA, and the second pixel may be provided in another area corresponding to the peripheral display area SA. Figure 6A and Figure 6B , the display modules 200 and 200-1 may emit green light and red light toward the user's finger, the green light and red light being emitted from the light-emitting device of the display device layer DP-OLED provided in the peripheral display area SA of the display panels 210 and 210-1. The green light and red light may be reflected by the user's finger and may be incident into the camera module 500 through the signal transmission area STA, and here, the reflected light may contain the user's biometric information. This will refer to Figure 7 Describe in more detail.
[0124] The input sensing portion 220 may be provided on the display panels 210 and 210-1. For example, the input sensing portion 220 of the flexible display module 200-1 may be provided directly on the flexible display panel 210-1, or may be coupled to the flexible display panel 210-1 via an adhesive member. The input sensing portion 220 may be formed on the flexible display panel 210-1 through a process performed continuously after the flexible display panel 210-1 is formed.
[0125] Figure 7 is a flowchart of a biometric information measuring method using an electronic device according to an embodiment of the inventive concept.
[0126] Reference Figure 7 The biometric information measurement method using an electronic device may include an operation of sensing a user's finger (not shown). The user's finger may be sensed by the light receiving sensor or the light receiving module LRM of the camera module 500. In the event of a touch event caused by the user, the user's finger may be sensed by an input sensing sensor (not shown) overlapping the second transmissive area HA2 of the input sensing portion 220.
[0127] A method for measuring biometric information using an electronic device may include operation S10 of operating a control module CM to execute a biometric information measurement mode when a user's finger is sensed. The biometric information measurement mode may include a mode for measuring the user's heart rate and a mode for measuring the oxygen saturation of hemoglobin in the user's blood. When the biometric information measurement mode is executed, the electronic device ED may provide a user interface (UI) or user experience (UX) that allows various inputs to the user through the active area AA of the display panel 210.
[0128] A method for measuring biometric information using an electronic device may include operation S20 in which the control module CM causes the second pixel of the display panel 210 to execute a high-emission mode. In the high-emission mode, detection light is emitted from the second pixel of the display panel 210 toward the user's finger. In the biometric information measurement method after operation S10, if an additional input is received from the user to initiate biometric information measurement, the control module CM of the electronic device ED may execute the high-emission mode to increase the amount of light emitted. For example, the high-emission mode may be a high-brightness mode (HBM) executed when the peripheral brightness is higher than a predetermined value. Specifically, the control module CM may cause the second pixel disposed in the peripheral display area SA of the display panel 210 to execute the high-emission mode via the driver chip DC of the driver circuit portion 300. When the high-emission mode is executed, the second pixel disposed in the peripheral display area SA of the display panel 210 may emit detection light having a brightness higher than the normal brightness (e.g., approximately 200 nm) of the light emitted from the first pixel in the main display area NSA.
[0129] For example, the second pixel may emit detection light having a maximum brightness of approximately 2000 nt. The detection light may be emitted in a high emission mode, and the high emission mode may include HBM and may include various emission modes in which the amount of light emitted from the light emitting device is maximized and the gamma value is controlled to maintain image quality. Here, the detection light may correspond to the light emitted from the second pixel to detect the user's biometric information during reflection from the user's finger. The detection light may include green light and red light. In an embodiment, the detection light may further include a small amount of blue light in addition to the green light and the red light. The green light can be used to measure the user's heart rate, and the red light together with the green light can be used to measure the oxygen saturation of hemoglobin in the user's blood.
[0130] A method for measuring biometric information using an electronic device may include operation S30 of sensing detection light reflected from a user's finger using a camera module. If the detection light is emitted from a second pixel in the peripheral display area SA, the detection light may be reflected from the user's finger. If the detection light is green light, a small portion of the detection light may be absorbed by the user's blood during reflection from the user's finger. During reflection from the user's finger, the detection light corresponding to the green light may sense changes in blood flow velocity in the user's finger, which is used to obtain information necessary to measure the user's heart rate. In other words, the camera module 500 may sense the amount of detection light reflected after being partially absorbed by the blood in the user's finger. The camera module 500 may sequentially sense green and red light emitted in a high-emission mode. For example, the control module CM may turn green or red light on or off depending on whether the high-emission mode is turned on or off. Although the high-emission mode is implemented for sensing efficiency, the control module CM may temporarily turn off the high-emission mode during the on-time of the green and red lights, which may help avoid light interference issues.
[0131] A method for measuring biometric information using an electronic device may include operation S40 of measuring a user's biometric information via the control module CM based on the amount of detected light. Specifically, since green light is partially absorbed by the user's blood, the amount of detection light corresponding to green light reflected from the user's finger may differ from the amount of detection light emitted from the second pixel, which is green light. In the electronic device, this difference can be used to measure changes in blood flow rate and, therefore, the user's heart rate. Hemoglobin oxygen saturation can be measured by comparing the intensities of green and red light in the detection light reflected from the user's finger and incident on the camera module 500.
[0132] The biometric information measuring method using an electronic device may include operation S50 of showing the measured biometric information to the user through the display panel 210. In the biometric information measuring method using an electronic device, the user's biometric information may be provided to the user in various ways through the user UI / UX.

[0134] like Figure 8A As shown in FIG, the peripheral display area SA-2 may be locally provided at a specific side of the signal transmission area STA. Figure 5 The peripheral display area SA-1 is different, Figure 8A An example is shown in which the peripheral display area SA-2, in which the first color pixels PX-G1, PX-G2, and the second color pixels PX-R are disposed, does not surround the signal transmission area STA and is locally disposed on a portion of the side of the signal transmission area STA. For example, the peripheral display area SA-2 may include three unit areas UA2 in which the second pixels are disposed. In an embodiment, the second pixels may be disposed on one of the right side, top side, and bottom side of the signal transmission area STA.
[0135] like Figure 8B As shown in , the display panel 210 may include a light blocking area BA surrounding the signal transmission area STA. The display panel 210 may include a light blocking pattern BM provided in the light blocking area BA. In an embodiment, the light blocking pattern BM may be provided in the window 100 and / or the display panel 210. In the case where the display panel 210 includes the light blocking pattern BM, the size of the light blocking area BA may be increased compared to the case where the light blocking pattern BM is not provided. The peripheral display area SA-3 may be provided near or around the light blocking area BA. Figure 8B As shown in , the area of the peripheral display area SA-3 may be reduced by the area of the light blocking area BA. In an embodiment, when the light blocking pattern BM is provided, the number of second pixels may be reduced in proportion to or according to the reduction in the size of the peripheral display area SA-3. Figure 8B shows that the number of the second pixels is reduced to Figure 5 The example of the number of the second pixels is 1 / 3, but the present inventive concept is not limited to this example. For example, even when the size of the light blocking area BA increases, the number of the second pixels may not change.
[0136] 9A to 9D 1 is a plan view showing a plurality of second pixels disposed in a unit area according to an embodiment of the present invention. The second pixel may have a red component and a green component. The arrangement of the second pixels in the unit area UA2 is not limited to 9A to 9D The examples shown in , and may be varied variously.
[0137] Reference Figure 9A, in one case of the second pixel, one of the pixels having the first area and the pixel having the second area are first color pixels PX-G1 and PX-G2 that emit green light, and another one of the pixels having the first area and the pixel having the third area may be second color pixels PX-R1 and PX-R2 that emit red light.
[0138] Reference Figure 9B , in the case of the second pixel, one of the pixels having the first area and the pixel having the third area may be first color pixels PX-G1 and PX-G2 emitting green light, and another pixel of the pixels having the first area and the pixel having the second area may be second color pixels PX-R1 and PX-R2 emitting red light.
[0139] Reference Figure 9C , in a variant case of the second pixel, two of the pixels having the first area may be second color pixels PX-R1 and PX-R2 that emit red light, and the pixel having the second area and the pixel having the third area may be first color pixels PX-G1 and PX-G2 that emit green light.
[0140] In an embodiment, in the case of the first pixel, a pixel having a first area may emit green light, a pixel having a second area may emit red light, and a pixel having a third area may emit blue light. Figure 9D In another case of the second pixel, one of the pixels having the first area may be a third color pixel PX-B emitting blue light, another of the pixels having the first area and the pixel having the second area may be first color pixels PX-G1 and PX-G2 emitting green light, and the pixel having the third area may be a second color pixel PX-R emitting red light. That is, even when the second pixel includes the third color pixel PX-B emitting blue light, the third color pixel PX-B may correspond to one of the pixels having the first area.
[0141] According to an embodiment of the inventive concept, by changing the arrangement of pixels near a front camera module and controlling the amount of light of the pixels near the front camera module, it may be possible to effectively measure biometric information of a user without requiring additional components.
[0142] Although certain embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Therefore, the inventive concept is not limited to such embodiments, but rather to the broader scope of the appended claims and various obvious modifications and equivalent arrangements as will be apparent to those skilled in the art.
