[0039] In this specification, when it is mentioned that a component (or area, layer, or part, etc.) is "set on", "connected to", or "coupled to" another component, it means that the component can be directly set on / directly connected to / directly coupled to the other component, or a third component can be set between the components.
[0040] The same reference numerals refer to the same components. Furthermore, in the drawings, the thickness, scale, and dimensions of the components are exaggerated for the purpose of effectively describing the technical content. The term "and / or" includes one or more combinations that can be defined by the relevant components.
[0041] Furthermore, terms such as "first" and "second" may be used when describing various components, but this disclosure is not limited by these terms. These terms are used only to distinguish components. For example, a first component may be named a second component without departing from the scope of this disclosure, and similarly, a second component may be named a first component. Unless the context clearly describes an exception, singular expressions also include plural expressions.
[0042] Furthermore, terms such as "below," "under," "above," and "over" are used to describe the relationships between the components shown in the accompanying drawings. These terms are relative concepts and are described relative to the directions indicated in the drawings.
[0043] In this specification, the term "direct installation" may mean that no additional layers, films, areas, or plates are attached between a component (such as a layer, film, area, or plate) and another component. For example, "direct installation" may mean installing two layers or two components without using additional components (such as adhesive components) between the two layers or two components.
[0044] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that, unless expressly defined herein, terms (such as those defined in general dictionaries) should be interpreted as having meanings consistent with their meanings in the context of this specification and the relevant technical field, and should not be interpreted in an idealized or overly formal sense.
[0045] The terms "component" and "unit" refer to software or hardware components that perform a specific function. Hardware components may include, for example, field-programmable gate arrays ("FPGAs") or application-specific integrated circuits ("ASICs"). Software components may refer to executable code and / or data used by the executable code in addressable storage media. Thus, for example, a software component may be an object-oriented software component, a class component, or a task component, and may include processes, functions, attributes, programs, subroutines, programming code segments, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, or may contain variables.
[0046] Embodiments of this disclosure will be described below with reference to the accompanying drawings.
[0047] Figure 1 This is a front view of an embodiment of the electronic device DD according to the present disclosure. Figure 2 This is a perspective view of an embodiment of the electronic device DD according to the present disclosure.
[0048] refer to Figure 1 and Figure 2 An electronic device DD can be a device activated by an electrical signal. Electronic devices DD can be applied to electronic devices such as mobile phones, computers (e.g., tablets, laptops), smartwatches, and smart TVs.
[0049] The electronic device DD can display images on a display surface IS parallel to the first direction DR1 and the second direction DR2. The display surface IS in which the image is displayed can correspond to the front surface of the electronic device DD. The image can include static images and dynamic images. The normal direction of the display surface IS (i.e., the thickness direction of the electronic device DD) is indicated by a third direction DR3. The front (or upper) surface and rear (or lower) surface of the layer or cell described below are divided by a third direction DR3.
[0050] The display surface IS of the electronic device DD can be divided into a display area DA and a non-display area NDA. The display area DA can be an area for displaying an image. The user visually identifies the image through the display area DA. In this embodiment, the display area DA is shown to have a quadrilateral shape, for example, a rectangle with rounded corners. However, this is shown as an illustrative embodiment, and the display area DA can have various shapes, and this disclosure is not limited to the specific embodiment.
[0051] The non-display area NDA is adjacent to the display area DA. The non-display area NDA may have a predetermined color. The non-display area NDA may surround the display area DA. Therefore, the shape of the display area DA may be substantially defined by the non-display area NDA. However, this is shown as an illustrative embodiment, and the non-display area NDA may be configured to be adjacent only to one side of the display area DA or may be omitted. The electronic device DD in the embodiments of this disclosure may include various embodiments, and this disclosure is not limited to a particular embodiment.
[0052] Figure 1 It can be a front view of the electronic device DD operating in either the first or second mode. Figure 2 This can be a side perspective view of the electronic device DD operating in a second mode. For example, in an embodiment, the first mode can be a normal mode, in which the image is displayed at a first viewing angle, and the second mode can be a privacy mode, in which the image is displayed at a second viewing angle smaller than the first viewing angle. The first and second viewing angles can be defined as angles relative to the normal direction of the display surface IS, at which image quality can be observed without distortion.
[0053] refer to Figure 1 In either the first or second mode, when the electronic device DD is viewed from the front (or in a direction parallel to the normal direction or the third direction DR3), the image IM generated on the electronic device DD can be visually recognized by the user. In the second mode, when the electronic device DD is viewed from an angle beyond the second viewing angle, the image IM may not be visually recognized.
[0054] The second viewing angle and the brightness at the second viewing angle can be set differently in the second mode. When the electronic device DD is viewed at an angle beyond the second viewing angle in the first mode, the user can visually recognize the image IM. For example, in an embodiment, the second viewing angle can be 45 degrees, and the brightness at 45 degrees can be 10% of the maximum brightness. In the first mode, the brightness at 45 degrees can be 20% or higher. However, this disclosure is not particularly limited thereto.
[0055] The electronic device DD can selectively operate in either a first mode or a second mode. In the first mode, the screen is displayed at a first-viewpoint, and in the second mode, the screen is displayed at a second-viewpoint smaller than the first-viewpoint. The switching between the first and second modes can be set by the user, or the mode can switch from the first mode to the second mode when a predetermined application is executed. For example, in an embodiment, when executing an application that carries the risk of exposing personal information (such as a banking or memo application), the electronic device DD can switch from the first mode to the second mode.
[0056] Figure 3 This is a cross-sectional view of an embodiment of the electronic device DD according to the present disclosure.
[0057] refer to Figure 3 The electronic device DD may include a display panel DP, an anti-reflective layer 300, and an upper functional layer 400. However, this is only one of several embodiments, and in another embodiment, the electronic device DD may not include the upper functional layer 400.
[0058] The display panel DP may include a display layer 100 and a sensor layer 200.
[0059] Display layer 100 may include a substrate layer 110, a circuit layer 120, a light-emitting element layer 130, and an encapsulation layer 140. Display layer 100 may be the component that actually generates the image. Display layer 100 may be a light-emitting display layer, and for example, display layer 100 may be an organic light-emitting display layer, an inorganic light-emitting display layer, an organic-inorganic light-emitting display layer, a quantum dot display layer, a micro light-emitting diode (“LED”) display layer, or a nano LED display layer.
[0060] The substrate layer 110 may be a component providing a substrate surface on which the circuit layer 120 is disposed. The substrate layer 110 may be a glass substrate, a metal substrate, a silicon substrate, or a polymer substrate. However, this disclosure is not limited thereto, and the substrate layer 110 may be an inorganic layer, an organic layer, or a composite material layer.
[0061] Circuit layer 120 may be disposed on substrate layer 110. Circuit layer 120 may include insulating layer, semiconductor pattern, conductive pattern, and signal lines. The insulating layer, semiconductor layer, and conductive layer may be formed on substrate layer 110 by coating or deposition, and then the insulating layer, semiconductor layer, and conductive layer may be selectively patterned by multiple photolithography processes. After this, semiconductor pattern, conductive pattern, and signal lines may be formed in circuit layer 120.
[0062] The light-emitting element layer 130 may be disposed on the circuit layer 120. The light-emitting element layer 130 may include a light-emitting element. For example, in an embodiment, the light-emitting element layer 130 may include organic light-emitting materials, inorganic light-emitting materials, organic-inorganic light-emitting materials, quantum dots, quantum rods, micro LEDs, or nano LEDs.
[0063] An encapsulation layer 140 may be disposed on the light-emitting element layer 130. The encapsulation layer 140 can protect the light-emitting element layer 130 from foreign matter (such as moisture, oxygen and dust particles).
[0064] Sensor layer 200 can detect external input applied from the outside. External input can be input from a user. User input can include various types of external input, such as a part of the user's body, light, heat, a pen, or pressure. Sensor layer 200 may also be referred to as a sensor, input sensing layer, or input sensing panel. Sensor layer 200 can be formed with display layer 100 through a continuous process and can be directly disposed on display layer 100. However, this disclosure is not particularly limited thereto. In embodiments, sensor layer 200 can be coupled to display layer 100 via an adhesive component. The adhesive component can include conventional adhesives.
[0065] An anti-reflective layer 300 may be disposed on the sensor layer 200. The anti-reflective layer 300 can reduce the reflectivity of external light input from outside the electronic device DD. The anti-reflective layer 300 may be disposed directly on the sensor layer 200. However, this disclosure is not limited thereto, and an adhesive component may be disposed between the anti-reflective layer 300 and the sensor layer 200.
[0066] The upper functional layer 400 can be disposed on the anti-reflective layer 300. The upper functional layer 400 can be used to cover the anti-reflective layer 300. In addition, the upper functional layer 400 can also be used as a planarization layer. Since the light emitted from the light-emitting element layer 130 must pass through the upper functional layer 400, the upper functional layer 400 can include an optically transparent material.
[0067] Figure 4 This is an enlarged plan view showing an embodiment of a portion of the display layer 100 according to the present disclosure.
[0068] refer to Figure 4 Display layer 100 (reference) Figure 3The first pixel group (WPX) may include a first pixel group (WPX) and a second pixel group (NPX). The first pixel group (WPX) may include pixels with a relatively wide viewing angle, and the second pixel group (NPX) may include pixels with a relatively narrow viewing angle. The first pixel group (WPX) may include pixel 1-1 (WPXR), pixel 1-2 (WPXG), and pixel 1-3 (WPXB). The second pixel group (NPX) may include pixel 2-1 (NPXR), pixel 2-2 (NPXG), and pixel 2-3 (NPXB). Each of the first pixel group (WPX) and the second pixel group (NPX) may include one red pixel, one blue pixel, and two green pixels. However, this is only one of several embodiments, and in another embodiment, the number of pixels may be different.
[0069] The first luminous region WPXAR can be confined within the first 1-1 pixel WPXR, the first 2 luminous region WPXAG can be confined within the first 2 pixel WPXG, and the first 3 luminous region WPXAB can be confined within the first 3 pixel WPXB. The first 1 luminous region WPXAR can be confined within the first 1-1 pixel WPXR. Figure 5A In the first-1 typical light-emitting element WPER described in the text, the first-2 light-emitting region WPXAG can be limited to the first-2 pixel WPXG. Figure 5A The first and second typical light-emitting elements described in the text are WPEG.
[0070] The second-first luminous region NPXAR can be confined within the second-first pixel NPXR, the second-second luminous region NPXAG can be confined within the second-second pixel NPXG, and the second-third luminous region NPXAB can be confined within the second-third pixel NPXB. The second-first luminous region NPXAR can be confined within the second-first pixel NPXR. Figure 5B In the second-1 typical light-emitting element NPER described in the figure, and the second-2 light-emitting region NPXAG can be confined in the second-2 pixel NPXG. Figure 5B The second-to-second typical light-emitting element NPEG is described in section 2-2. As used herein, the term "typical / type" may refer to a specific type or example configuration.
[0071] In the following text, the first-1 luminescent region WPXAR, the first-2 luminescent region WPXAG, and the first-3 luminescent region WPXAB can also be referred to as the first luminescent region WPXAR, WPXAG, and WPXAB, and the second-1 luminescent region NPXAR, the second-2 luminescent region NPXAG, and the second-3 luminescent region NPXAB can also be referred to as the second luminescent region NPXAR, NPXAG, and NPXAB.
[0072] Figure 4The circular shapes shown can correspond to the shapes of the first luminous regions WPXAR, WPXAG, and WPXAB, and the second luminous regions NPXAR, NPXAG, and NPXAB, respectively. However, the shapes of the first luminous regions WPXAR, WPXAG, and WPXAB, and the second luminous regions NPXAR, NPXAG, and NPXAB are not limited to these. For example, in embodiments, the first luminous regions WPXAR, WPXAG, and WPXAB, and the second luminous regions NPXAR, NPXAG, and NPXAB can have various shapes in a planar view, such as quadrilateral shapes (e.g., rectangular shapes), other polygonal shapes (e.g., triangular shapes), elliptical shapes, or atypical shapes.
[0073] In the embodiments of this disclosure, the first-1 pixel WPXR and the second-1 pixel NPXR, the first-2 pixel WPXG and the second-2 pixel NPXG, and the first-3 pixel WPXB and the second-3 pixel NPXB may each have the same shape. Furthermore, the first-1 light-emitting area WPXAR and the second-1 light-emitting area NPXAR, the first-2 light-emitting area WPXAG and the second-2 light-emitting area NPXAG, and the first-3 light-emitting area WPXAB and the second-3 light-emitting area NPXAB may each have the same shape.
[0074] In embodiments of this disclosure, the first pixel group WPX and the second pixel group NPX can be alternately and repeatedly arranged along diagonal directions CDR1 and CDR2. The first pixel group WPX's first-1 pixel WPXR and first-3 pixel WPXB can be alternately arranged one after another along the second direction DR2. Furthermore, the second pixel group NPX's second-1 pixel NPXR and second-3 pixel NPXB can be alternately arranged one after another along the second direction DR2. The first pixel group WPX's first-2 pixel WPXG can be arranged along diagonal directions CDR1 and CDR2 along the first pixel WPXR and first-3 pixel WPXB. The second pixel group NPX's second-2 pixel NPXG can be arranged along diagonal directions CDR1 and CDR2 along the second pixel NPX's second-1 pixel NPXR and second-3 pixel NPXB.
[0075] The first diagonal direction CDR1 can be a direction between the first direction DR1 and the second direction DR2, and the second diagonal direction CDR2 can be a direction opposite to the first direction DR1 and between the second direction DR2. However, Figure 4The arrangement of the first-1 pixel WPXR, the first-2 pixel WPXG, and the first-3 pixel WPXB, as well as the second-1 pixel NPXR, the second-2 pixel NPXG, and the second-3 pixel NPXB shown, is one of several embodiments, and the arrangement of the first-1 pixel WPXR, the first-2 pixel WPXG, and the first-3 pixel WPXB, as well as the second-1 pixel NPXR, the second-2 pixel NPXG, and the second-3 pixel NPXB, is not particularly limited to this.
[0076] In embodiments of this disclosure, each of the first pixel group WPX and the second pixel group NPX may be driven or not driven according to a first mode or a second mode. The first mode may be a normal mode, in which both the first pixel group WPX and the second pixel group NPX may be driven. The second mode may be a privacy mode, in which the first pixel group WPX is not driven and only the second pixel group NPX is driven.
[0077] Figure 5A This is a cross-sectional view illustrating an embodiment of an electronic device DD according to this disclosure. For example, in the embodiment, Figure 5A It is a cross-sectional view including an embodiment of the display layer 100 according to the present disclosure, the cross-sectional view along... Figure 4 The first pixel group WPX shown is cut off by line I-I'.
[0078] refer to Figure 5A At least one inorganic layer is formed on the upper surface of the substrate layer 110. The inorganic layer may include at least one of alumina, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide. The inorganic layer may be formed in multiple layers. Multiple inorganic layers may constitute a barrier layer and / or a buffer layer. In this embodiment, the display layer 100 is shown to include a buffer layer BFL.
[0079] The buffer layer BFL can improve the coupling strength between the substrate layer 110 and the semiconductor pattern. The buffer layer BFL may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. For example, in an embodiment, the buffer layer BFL may include a structure in which silicon oxide layers and silicon nitride layers are alternately stacked.
[0080] Semiconductor patterns can be formed on the buffer layer BFL. The semiconductor pattern may include polycrystalline silicon. However, this disclosure is not limited thereto, and the semiconductor pattern may include amorphous silicon, low-temperature polycrystalline silicon, or oxide semiconductor.
[0081] Figure 5AOnly some semiconductor patterns are shown, and additional semiconductor patterns can be set in other areas. Semiconductor patterns can be set across pixels according to predetermined rules. Semiconductor patterns can have different electrical properties depending on whether they are doped. A semiconductor pattern can include a first region with relatively high conductivity and a second region with relatively low conductivity. The first region can be doped with N-type or P-type dopant. A P-type transistor can include a doped region doped with P-type dopant, and an N-type transistor can include a doped region doped with N-type dopant. The second region can be an undoped region or a region doped at a lower concentration than the first region.
[0082] The conductivity of the first region is greater than that of the second region, and it can essentially be used as an electrode or signal line. The second region can essentially correspond to the active region (or channel) of a transistor. In other words, a portion of the semiconductor pattern can be the active region of a transistor, another portion can be the source or drain region of a transistor, and yet another portion can be a connecting electrode or a connecting signal line.
[0083] Each of the multiple pixels may include pixel circuitry and a light-emitting element. Pixel circuitry may include multiple transistors and at least one capacitor.
[0084] The source region SC, active region AL, and drain region DR of transistor 100PC can be formed by semiconductor patterning. The source region SC and drain region DR can extend in opposite directions from the active region AL in the cross section. Figure 5A A portion of the connection signal line SCL, formed by a semiconductor pattern, is shown. Although not shown separately, in the plan view, the connection signal line SCL can be connected to the drain region DR of transistor 100PC.
[0085] The first insulating layer 10 may be disposed on the buffer layer BFL. The first insulating layer 10 may overlap with multiple pixels in a common area while covering a semiconductor pattern. The first insulating layer 10 may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multi-layer structure. The first insulating layer 10 may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide. In this embodiment, the first insulating layer 10 may be a single layer of silicon oxide. The first insulating layer 10 and the insulating layer of the circuit layer 120, which will be described later, may be inorganic layers and / or organic layers, and may have a single-layer structure or a multi-layer structure. The inorganic layer may include at least one of the above-described materials, but this disclosure is not limited thereto.
[0086] The gate GT of transistor 100PC is disposed on the first insulating layer 10. The gate GT may be part of a metal pattern. The gate GT overlaps with the active region AL. In a process of doping semiconductor patterns, the gate GT may be used as a mask.
[0087] The second insulating layer 20 may be disposed on the first insulating layer 10 and may cover the gate GT. The second insulating layer 20 may commonly overlap with the pixel. The second insulating layer 20 may be an inorganic layer and / or an organic layer, and may have a single-layer structure or a multilayer structure. The second insulating layer 20 may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. In this embodiment, the second insulating layer 20 may have a multilayer structure including a silicon oxide layer and a silicon nitride layer.
[0088] The third insulating layer 30 may be disposed on the second insulating layer 20. The third insulating layer 30 may have a single-layer structure or a multi-layer structure.

The sensor cover layer 250 may include an inorganic material. For example, in an embodiment, the sensor cover layer 250 may include silicon nitride, but this disclosure is not particularly limited thereto. In embodiments of this disclosure, the sensor cover layer 250 may be omitted.
[0112] An anti-reflective layer 300 may be disposed on the sensor layer 200. The anti-reflective layer 300 may include a light-shielding layer 310, a plurality of first color filters 320, an inorganic layer 330, and a planarization layer 340.

[0116] In embodiments of this disclosure, the inorganic layer 330 may be disposed throughout the first color filter 320. The inorganic layer 330 may be formed to cover the first color filter 320.

[0118] In embodiments of this disclosure, the upper functional layer 400 may be disposed on the antireflective layer 300. For example, in one embodiment, the upper functional layer 400 may include an outer coating layer. Therefore, the antireflective layer 300 can be protected from external influences. However, this is only one of several embodiments, and in another embodiment, the upper functional layer 400 may be omitted.

Figure 5B The cross-sectional structure of the typical light-emitting element NPEG shown in Figure 2-2 is basically the same. Therefore, in Figure 5B The cross-sectional structures of typical light-emitting elements NPER (2-1) and NPEG (2-2) are shown in the diagram. The description of typical light-emitting elements NPEG (2-3) will be omitted in the following text.

Figure 4 The cross-sectional view of ) and Figure 5B The cross-sectional view shown is a cross-sectional view including the second pixel group NPX, which has a relatively narrow field of view. Figure 5A and Figure 5B The substrate layer 110, circuit layer 120, encapsulation layer 140 and sensor layer 200 of the display layer 100 shown are substantially the same, and therefore a description of them will be omitted.
[0123] refer to Figure 5B The light-emitting element layer 130 may include second typical light-emitting elements NPER and NPEG, wherein second light-emitting regions NPXAR and NPXAG are defined in the second typical light-emitting elements NPER and NPEG, respectively. For example, in an embodiment, each of the second typical light-emitting elements NPER and NPEG may include an organic light-emitting material, an inorganic light-emitting material, an organic-inorganic light-emitting material, a quantum dot, a quantum rod, a micro LED, or a nano LED. Hereinafter, the second typical light-emitting elements NPER and NPEG will be described in an embodiment in which each of the second typical light-emitting elements NPER and NPEG is an organic light-emitting element, but this disclosure is not particularly limited thereto.
[0124] The second typical light-emitting elements NPER and NPEG may include the second-first typical light-emitting element NPER and the second-second typical light-emitting element NPEG. The second-first typical light-emitting element NPER may include the second-first pixel electrode NAER, the second-first emissive layer NELR, and the common electrode CE. The second-second typical light-emitting element NPEG may include the second-second pixel electrode NAEG, the second-second emissive layer NELG, and the common electrode CE. The common electrode CE included in the second-first typical light-emitting element NPER and the second-second typical light-emitting element NPEG may be provided in an integral form. The second-first pixel electrode NAER and the second-second pixel electrode NAEG may also be referred to as the first electrode NAER and NAEG or the anode. The common electrode CE may also be referred to as the second electrode CE or the cathode. The second-first pixel electrode NAER and the second-second pixel electrode NAEG may also be referred to as the second pixel electrode NAER and NAEG; the second-first emissive layer NELR and the second-second emissive layer NELG may also be referred to as the second emissive layer NELR and NELG. The aforementioned second pixel electrodes NAER and NAEG, as well as the second light-emitting layers NELR and NELG, can be respectively connected to... Figure 5A The first electrodes WAER and WAEG, as well as the first light-emitting layers WELR and WELG, described in the text are essentially the same.
[0125] Figure 5B A cross-sectional view of two second typical light-emitting elements, NPER and NPEG, is shown as an illustrative embodiment. Figure 5B The descriptions of the second typical light-emitting elements NPER and NPEG shown can be compared with... Figure 5A The descriptions of the first typical light-emitting elements WPER and WPEG shown are essentially the same.
[0126] Display area DA (reference) Figure 1 This may include the second luminescent regions NPXAR and NPXAG, as well as the non-luminescent regions adjacent to (adjacent to) the second luminescent regions NPXAR and NPXAG. The descriptions of the second luminescent regions NPXAR and NPXAG may be consistent with... Figure 5A The descriptions of the first luminescent region, WPXAR and WPXAG, are essentially the same.
[0127] In embodiments of this disclosure, the antireflective layer 300 may include a light-shielding layer 310, in which a plurality of openings NOPR and NOPG are defined. The openings NOPR and NOPG may overlap with second light-emitting regions NPXAR and NPXAG defined in second typical light-emitting elements NPER and NPEG, respectively, and may also be referred to as second openings NOPR and NOPG. The second openings NOPR and NOPG may be defined by a second sidewall 310b of the light-shielding layer 310. Figure 5AThe ranges of the first openings WOPR and WOPG corresponding to the first light-emitting regions WPXAR and WPXAG shown can be larger than the ranges of the second openings NOPR and NOPG. Therefore, the amount of light emitted from the second typical light-emitting elements NPER and NPEG and that can be visually recognized by the user will be less than the amount of light emitted from the first typical light-emitting elements WPER and WPEG and that can be visually recognized by the user. In an embodiment, for example, in... Figure 5A In the middle, the user can visually identify the light emitted by AG1 at the first angle, but... Figure 5B In the middle, the light is blocked by the light-blocking layer 310, and therefore, the user cannot visually perceive the light emitted at the first angle AG1.
[0128] The antireflective layer 300 may include second color filters N320R and N320G. The second color filters N320R and N320G may include a second-first color filter N320R and a second-second color filter N320G. The second-first color filter N320R and the second-second color filter N320G may be configured to correspond to the second openings NOPR and NOPG, respectively. The second-first color filter N320R and the second-second color filter N320G may transmit light emitted from second typical light-emitting elements NPER and NPEG, respectively, which overlap with the second-first color filter N320R and the second-second color filter N320G. Figure 5B The second openings NOPR and NOPG, as well as the second color filters N320R and N320G, are shown as illustrative embodiments.
[0129] In embodiments of this disclosure, the upper functional layer 400 may include a light-shielding pattern 410, a color filter pattern 420, and an outer coating layer 430.
[0130] A light-shielding pattern 410 may be disposed on the anti-reflective layer 300 and may be configured to surround the second luminescent regions NPXAR and NPXAG. The light-shielding pattern 410 may comprise, or be composed of, a material substantially the same as, the material of the light-shielding layer 310 of the anti-reflective layer 300. Therefore, the light-shielding pattern 410 may comprise a black colorant capable of preventing reflection of external light and absorbing light. In embodiments of this disclosure, the light-shielding pattern 410 may be configured to overlap with the second sidewall 310b defining the second openings NOPR and NOPG of the light-shielding layer 310. Therefore, when the light-shielding pattern 410 is formed together with the light-shielding layer 310, a smaller viewing angle can be displayed compared to a structure where only the light-shielding layer 310 is formed. When a smaller viewing angle is formed, a strong privacy mode can be established, further protecting privacy. However, this disclosure is not limited thereto, and the light-shielding pattern 410 may not overlap with the second sidewall 310b of the light-shielding layer 310.
[0131] In the plan view, the color filter pattern 420 can be formed to overlap with and cover the light-shielding pattern 410. A portion of the color filter pattern 420 can be disposed on the anti-reflective layer 300, and the remaining portion can be disposed on the light-shielding pattern 410. The color filter pattern 420 can be configured to surround the second-first luminous region NPXAR, and may not surround the second-second luminous region NPXAG. However, this disclosure is not limited thereto, and may be configured to further surround the second-second luminous region NPXAG.
[0132] In embodiments of this disclosure, the second typical light-emitting elements NPER and NPEG can be driven in both a first mode as a normal mode and a second mode as a privacy mode. However, in the second mode, the first typical light-emitting elements WPER and WPEG (refer to...) Figure 5A It can be undriven. Therefore, the second mode can be displayed from a second perspective, smaller than the first mode's first perspective.
[0133] In embodiments of this disclosure, the light-blocking pattern 410 can block light emitted from the second typical light-emitting elements NPER and NPEG, and the color filter pattern 420 can absorb light emitted from the corresponding second-first typical light-emitting elements NPER and NPEG. The light emitted by the second-first typical light-emitting element NPER can then be red light. Hereinafter, it will be described by way of example that the light emitted by the second-first typical light-emitting element NPER is red light.
[0134] Compare Figure 5A and Figure 5B , Figure 5A The cross-sectional view shown may include a light-shielding layer 310, in which first openings WOPR and WOPG are defined, but may not include the light-shielding pattern 410 and the color filter pattern 420. Therefore, in the first mode, light emitted from the first-1 typical light-emitting element WPER at a first angle AG1 and a second angle AG2 can be visually recognized by the user.
[0135] Figure 5BThe cross-sectional view shown may include the entirety of the light-shielding layer 310 defining the second openings NOPR and NOPG, the light-shielding pattern 410 surrounding the second light-emitting regions NPXAR and NPXAG, and the color filter pattern 420 surrounding the second-first light-emitting region NPXAR. As described above, the ranges of the second openings NOPR and NOPG are smaller than the ranges of the first openings WOPR and WOPG. In both the first and second modes, light emitted from the second-first typical light-emitting element NPER at a first angle AG1 can be blocked by the light-shielding layer 310, which defines the second opening NOPR corresponding to the second-first typical light-emitting element NPER. Furthermore, light emitted from the second-first typical light-emitting element NPER at a second angle AG2 can be blocked by the light-shielding pattern 410 surrounding the second-first typical light-emitting element NPER. In this case, light traveling at a third angle AG3, which is smaller than the first angle AG1 and larger than the second angle AG2, while being emitted from the second-first typical light-emitting element NPER, may not be blocked by the light-shielding pattern 410. Therefore, in both the first and second modes, when a user moves from a relatively low angle to a relatively high angle relative to the normal, the user may visually identify a portion of the emitted light. For example, in an embodiment, when the light emitted from the second-first typical light-emitting element NPER is red light, the user may visually identify red light at a relatively high angle.
[0136] However, when emitted from the second-first typical light-emitting element NPER, light traveling at a third angle AG3 that is less than the first angle AG1 and greater than the second angle AG2 can be blocked by the color filter pattern 420 overlapping with the light-blocking pattern 410. When the light emitted by the second-first typical light-emitting element NPER is red light, the color filter pattern 420 can be a green color filter. Since the color filter pattern 420 can absorb red light, the problem of the image being visually perceived as red due to the red light being emitted at a relatively high angle can be improved (or eliminated). Therefore, display quality can be improved even at a relatively high angle from the user's perspective. Then, when it can absorb the light emitted by the second-first typical light-emitting element NPER, the color filter pattern 420 can be a blue color filter.
[0137] In embodiments of this disclosure, an outer coating 430 may be disposed on the antireflective layer 300. Then, a light-shielding pattern 410 and a color filter pattern 420 may be disposed between the antireflective layer 300 and the outer coating 430. Furthermore, the color filter pattern 420 may be disposed between the light-shielding pattern 410 and the outer coating 430. Therefore, the outer coating 430 can be formed to cover the antireflective layer 300, the light-shielding pattern 410, and the color filter pattern 420, and can protect the antireflective layer 300, the light-shielding pattern 410, and the color filter pattern 420. Because from the first typical light-emitting elements WPER and WPEG (reference...) Figure 5AThe light emitted by the second typical light-emitting elements NPER and NPEG must be transmitted, so the outer coating 430 may include or be composed of transparent materials.
[0138] Figure 6A This is a plan view illustrating an embodiment of a portion of the light-shielding layer 310 according to the present disclosure. Figure 6A It shows the relationship with Figure 4 The diagram shows a plan view of the light-shielding layer 310 corresponding to the first pixel group WPX and the second pixel group NPX.
[0139] refer to Figure 6A The light-shielding layer 310 can define a plurality of openings WOPR, WOPG, WOPB, NOPR, NOPG, and NOPB corresponding to the first light-emitting regions WPXAR, WPXAG, and WPXAB of the first pixel group WPX and the second light-emitting regions NPXAR, NPXAG, and NPXAB of the second pixel group NPX. For example, in an embodiment, the plurality of openings WOPR, WOPG, WOPB, NOPR, NOPG, and NOPB may include first openings WOPR, WOPG, and WOPB that overlap with the first light-emitting regions WPXAR, WPXAG, and WPXAB, and second openings NOPR, NOPG, and NOPB that overlap with the second light-emitting regions NPXAR, NPXAG, and NPXAB.
[0140] The first openings WOPR, WOPG, and WOPB can be defined by the first sidewall 310a of the light-shielding layer 310, and the second openings NOPR, NOPG, and NOPB can be defined by the second sidewall 310b of the light-shielding layer 310. From the first typical light-emitting elements WPER and WPEG of the first pixel group WPX (reference... Figure 5A The light emitted can be visually recognized by the user through the first opening WOPR and WOPG. The second typical light-emitting elements NPER and NPEG (reference) of the second pixel group NPX. Figure 5B The emitted light can be visually identified by the user through the second apertures NOPR and NOPG. Therefore, in the first mode, the user can visually identify the light through both the first apertures WOPR, WOPG, and WOPB, and the second apertures NOPR, NOPG, and NOPB. In the second mode, the light can be visually identified solely through the second apertures NOPR, NOPG, and NOPB.
[0141] The ranges of the first openings WOPR, WOPG, and WOPB and the second openings NOPR, NOPG, and NOPB defined in the light-shielding layer 310 can be different from each other. Therefore, the angles of light that can be visually perceived by the user can be different from each other. In embodiments of this disclosure, the ranges of the first openings WOPR, WOPG, and WOPB can be larger than the ranges of the second openings NOPR, NOPG, and NOPB. Then, in the second mode, the user can have a relatively smaller viewing angle that differs from the viewing angle in the first mode.
[0142] Figure 6B This is a plan view illustrating an embodiment of a portion of the light-shielding pattern 410 according to this disclosure. Figure 6B It shows the relationship with Figure 4 The plan view of the light-blocking pattern 410 corresponding to the first pixel group WPX and the second pixel group NPX shown.
[0143] refer to Figure 6A and Figure 6B The light-shielding pattern 410 may not be provided on the first light-emitting areas WPXAR, WPXAG, and WPXAB of the first pixel group WPX, but may only be provided on the light-emitting areas NPXAR, NPXAG, and NPXAB of the second pixel group NPX. The light-shielding pattern 410 may have a shape surrounding the second-first light-emitting area NPXAR. Then, only the light-shielding layer 310 may be provided on the first light-emitting areas WPXAR, WPXAG, and WPXAB of the first pixel group WPX, and the light-shielding layer 310 and the light-shielding pattern 410 surrounding the second-first light-emitting area NPXAR of the second pixel group NPX may be provided. Therefore, from the second-first typical light-emitting element NPER (reference) Figure 5B Even if the high-angle light emitted is not blocked by the light-blocking layer 310, it can be blocked by the light-blocking pattern 410.
[0144] In embodiments of this disclosure, the light-shielding pattern 410 may have an annular shape surrounding the second-first luminescent region NPXAR. However, this is only one of several embodiments, and in another embodiment, it may have a shape other than an annular shape, such as a polygonal shape.
[0145] In embodiments of this disclosure, a plurality of light-shielding patterns 410 may be provided. The plurality of light-shielding patterns 410 will be formed not only around the 2-1 light-emitting region NPXAR, but also around the 2-2 light-emitting region NPXAG and the 2-3 light-emitting region NPXAB. With the light-shielding patterns 410 being provided, both the light-shielding layer 310 and the light-shielding patterns 410 can also be provided on the 2-2 light-emitting regions NPXAG and 2-3 light-emitting regions NPXAB, just as they are on the 2-1 light-emitting region NPXAR. Therefore, from the 2-2 typical light-emitting element NPEG (reference...) Figure 5B The high-angle light emitted by the second and third typical light-emitting elements can be blocked by the light-blocking pattern 410 even if it is not blocked by the light-blocking layer 310.
[0146] In embodiments of this disclosure, the light-shielding patterns 410 may have a shape that is connected to each other. When the light-shielding patterns 410 are connected to each other, it is possible to prevent delamination due to external environment and processes. However, this disclosure is not limited thereto, and the light-shielding patterns 410 may have a separate island shape.
[0147] Figure 6C This is a plan view illustrating an embodiment of a color filter pattern 420 according to the present disclosure. Figure 6C It shows the relationship with Figure 4 The diagram shows a plan view of the color filter pattern 420 corresponding to the first pixel group WPX and the second pixel group NPX.
[0148] refer to Figure 6A , Figure 6B and Figure 6C The color filter pattern 420 can be configured to surround the 2-1 luminescent region NPXAR, while the 2-2 luminescent region NPXAG and the 2-3 luminescent region NPXAB can be left unsurrounded. The color filter pattern 420 can absorb light from the 2-1 typical luminescent element NPER (reference). Figure 5B The light emitted by the second-1 typical light-emitting element NPER (reference) is described. In embodiments of this disclosure, the second-1 typical light-emitting element is described. Figure 5B The color filter pattern 420, which can emit red light, and is configured to surround the 2-1 luminescent region NPXAR, can be a green color filter that can absorb red light. However, this disclosure is not limited thereto; the color filter pattern 420 can also be a blue color filter that can absorb red light.
[0149] In embodiments of this disclosure, a light-shielding layer 310 surrounding the first light-emitting regions WPXAR, WPXAG, and WPXAB can be provided only on the first pixel group WPX, and a light-shielding layer 310 and a light-shielding pattern 410 surrounding the second light-emitting regions NPXAR, NPXAG, and NPXAB can be provided on the second pixel group NPX. Furthermore, a color filter pattern 420 surrounding the second-first light-emitting region NPXAR can be provided on the second pixel group NPX. Because both the first pixel group WPX and the second pixel group NPX are driven in the first mode, and only the second pixel group NPX is driven in the second mode, the second viewing angle in the second mode is smaller than the first viewing angle in the first mode. For example, in an embodiment, the second-second typical light-emitting element NPEG (reference) of the second-second pixel NPXG driven in the second mode... Figure 5BThe light emitted by the light-emitting element (NPER) can be blocked by the light-blocking pattern 410 even if it is not blocked by the light-blocking layer 310. Furthermore, the light emitted by the second-first typical light-emitting element (NPER) of the second-first pixel NPXR driven in the second mode (reference...) Figure 5B Even if the emitted light is not blocked by the light-blocking layer 310, it can be blocked by the light-blocking pattern 410, and the high-angle light that is not blocked by the light-blocking pattern 410 can be blocked by the color filter pattern 420. Therefore, the problem of the image being visually perceived as red due to the high-angle emitted light can be improved by the color filter pattern 420, and the display quality can be improved.
[0150] Figure 7 This is a plan view showing an embodiment of a portion of the light-shielding pattern 410 and a portion of the color filter pattern 420 according to the present disclosure.
[0151] refer to Figure 7 The light-blocking pattern 410 and the color filter pattern 420 can be set to surround the 2-1 luminescent area NPXAR (reference). Figure 6C Therefore, from the 2-1 pixel NPXR, the 2-1 typical light-emitting element NPER (reference) Figure 5B The emitted light can be blocked by the light-blocking pattern 410 and the color filter pattern 420.
[0152] The light-blocking pattern 410 may have a first width L1, and the color filter pattern 420 may have a second width L2. When viewed on a third-direction DR3, the first width L1 and the second width L2 may correspond to the distances between the inner and outer diameters of the light-blocking pattern 410 and the color filter pattern 420, respectively.
[0153] In embodiments of this disclosure, the first width L1 may be smaller than the second width L2. Therefore, in a plan view, the color filter pattern 420 may overlap entirely with the annular light-shielding pattern 410. When the first width L1 of the light-shielding pattern 410 is smaller than the second width L2 of the color filter pattern 420, the light emission from the second-1st typical light-emitting element NPER (reference)... Figure 5B Light emitted at a relatively high angle can be blocked by the color filter pattern 420 even if it is not blocked by the light-blocking pattern 410. For example, in an embodiment, when light emitted from the second-first typical light-emitting element NPER (reference) Figure 5B When the emitted light is red, the red light emitted at a relatively high angle can be blocked by the color filter pattern 420, thereby improving the display quality. However, this disclosure is not limited to this, and the widths of the light-blocking pattern 410 and the color filter pattern 420 can be the same, or the width of the light-blocking pattern 410 can be larger.
[0154] Figure 8 This is a cross-sectional view illustrating an embodiment of the electronic device DDA according to this disclosure. For example, in the embodiment, Figure 8 It is along Figure 4 The cross-sectional view shown is taken from line II-II' of the second pixel group NPX. Figure 8 In the description, with Figure 5B The components described herein use the same reference numerals, and their descriptions will be omitted.
[0155] refer to Figure 8 The electronic device DDA may include a display layer 100, a sensor layer 200, an anti-reflective layer 300, and an upper functional layer 400a. The upper functional layer 400a may include a light-shielding pattern 410, a color filter pattern 420a, and an outer coating layer 430.
[0156] In embodiments of this disclosure, an outer coating layer 430 may be disposed on the antireflective layer 300, and a light-shielding pattern 410 may be disposed between the antireflective layer 300 and the outer coating layer 430. Furthermore, a color filter pattern 420a may be disposed on the outer coating layer 430 and may be spaced apart from the light-shielding pattern 410, with the outer coating layer 430 situated between the light-shielding pattern 410 and the color filter pattern 420a. In a plan view, the color filter pattern 420a may overlap with the light-shielding pattern 410 while surrounding the second-first luminescent region NPXAR.
[0157] The color filter pattern 420a disposed on the outer coating 430 can absorb light emitted from the second-first typical light-emitting element NPER. Even when the light-shielding pattern 410 does not block the light emitted from the second-first typical light-emitting element NPER, light emitted at a relatively high angle can still be blocked by the color filter pattern 420a. In the embodiment, light emitted from the second-first typical light-emitting element NPER traveling at a first angle AG1 can be blocked by the light-shielding layer 310, and light traveling at a second angle AG2 can be blocked by the light-shielding pattern 410. Then, light traveling at a third angle AG3, which is less than the first angle AG1 and greater than the second angle AG2, can be blocked by the color filter pattern 420a disposed on the outer coating 430.
[0158] Figure 9 This is a cross-sectional view illustrating an embodiment of an electronic device DDb according to the present disclosure. For example, in the embodiment, Figure 9 It is along Figure 4 The cross-sectional view shown is taken from line II-II' of the second pixel group NPX. Figure 9 In the description, with Figure 5B The components described herein use the same reference numerals, and their descriptions will be omitted.
[0159] refer to Figure 9The electronic device DDb may include a display layer 100, a sensor layer 200, an anti-reflective layer 300, and an upper functional layer 400b. The upper functional layer 400b may include a first light-shielding pattern 410a, a second light-shielding pattern 410b, a color filter pattern 420a, and an outer coating layer 430.
[0160] In embodiments of this disclosure, a first light-shielding pattern 410a may be disposed on the anti-reflective layer 300. Furthermore, a second light-shielding pattern 410b and a color filter pattern 420a may be disposed on the outer coating layer 430. In a plan view, the color filter pattern 420a may overlap with the first light-shielding pattern 410a and the second light-shielding pattern 410b. The color filter pattern 420a may be formed to cover the second light-shielding pattern 410b.
[0161] The first light-shielding pattern 410a can be formed around the second light-emitting regions NPXAR and NPXAG. The second light-shielding pattern 410b and the color filter pattern 420a can be formed around the second-first light-emitting region NPXAR among the second light-emitting regions NPXAR and NPXAG. Therefore, the light emitted from the second-first typical light-emitting element NPER can be blocked by the first light-shielding pattern 410a, the second light-shielding pattern 410b, and the color filter pattern 420a.
[0162] High-angle emitted light that is not blocked by the first light-blocking pattern 410a can be blocked by the second light-blocking pattern 410b and the color filter pattern 420a. For example, in an embodiment, when the light emitted from the second-first typical light-emitting element NPER is red light, high-angle red light traveling at a third angle AG3 that is less than the first angle AG1 and greater than the second angle AG2 can be blocked by the second light-blocking pattern 410b and the color filter pattern 420a, thereby improving display quality.
[0163] Based on the above, the electronic device may include a light-shielding pattern and a color filter pattern. The color filter pattern can absorb red light emitted at a relatively high angle. Even if the light-shielding pattern cannot block red light, red light emitted at a relatively high angle can be blocked by the color filter pattern. Therefore, even at a relatively high angle from the user's perspective (from the user's perspective, at a relatively high angle), the display quality can be improved by mitigating (or eliminating) the problem of the image being visually perceived as red due to red light emitted at a relatively high angle.
[0164] Although this disclosure has been described with reference to embodiments, those skilled in the art will understand that modifications and changes can be made to this disclosure within the scope of the appended claims without departing from its spirit and scope. Therefore, the technical scope of this disclosure should not be limited to the detailed description herein, but rather all technical ideas in the claims and their equivalents fall within the scope of this disclosure.
