[0002] This disclosure relates to display modules and electronic devices including display modules. More specifically, this disclosure relates to display modules including multiple diffraction reduction sections to reduce diffraction patterns visible to a user and electronic devices including display modules. Background Technology

[0003] A display panel may include multiple pixels configured to emit light to a user, displaying visual information. When multiple pixels with identical shapes are arranged at constant intervals, a diffraction grating may be formed due to the multiple pixels. Because of the formation of the diffraction grating, a diffraction pattern may be visible in the light emitted from the display panel. Furthermore, because of the formation of the diffraction grating, a diffraction pattern may also be visible in the light reflected by the display panel. Both the diffraction grating and the diffraction pattern may lead to a reduction in display quality. Summary of the Invention

[0038] Figure 2 This is a cross-sectional view of a display device DD according to an embodiment of the present disclosure.

[0039] Reference Figure 2 The display device DD may include a display module DPM, a window component WP, and an adhesive component OCA. Figure 2 For the sake of simplicity, the stacked structure of the display device DD is shown in the diagram.

[0040] The display module (DPM) may include a display panel (DP), an input sensor unit (ISP), and a reflective protective layer (RPL). The display module (DPM) can be configured to emit light through a window member (WP).

In embodiments, the display panel DP can be an organic light-emitting display panel, a quantum dot light-emitting display panel, or a micro light-emitting display panel.

In embodiments, at least one of a capacitive input sensor, a resistive input sensor, an optical sensor, an electromagnetic resonant input sensor, an ultrasonic input sensor, and an infrared input sensor can be used as the input sensor unit (ISP).

The reflective protective layer (RPL) can be configured to reduce the light reflectivity of external light incident from the upper side of the window member (WP). The reflective protective layer (RPL) may include a color filter layer.

[0044] The reflective protective layer RPL may not include a polarizing film. Therefore, the reflective protective layer RPL can allow the transmission of at least some of the light rays that are orthogonal to each other. Furthermore, the reflective protective layer RPL can allow the transmission of at least some of the light rays that oscillate in a direction parallel to the plane defined by the first direction DR1 and the second direction DR2.

[0045] For example, the reflective protective layer RPL can allow the transmission of at least some of the light oscillating in the first direction DR1 and at least some of the light oscillating in the second direction DR2. The light transmittance of the light transmitted through the reflective protective layer RPL and oscillating in the first direction DR1 and the light transmittance of the light transmitted through the reflective protective layer RPL and oscillating in the second direction DR2 can be substantially the same as each other.

[0046] The window component WP can be disposed on the reflective protective layer RPL (e.g., directly disposed on the reflective protective layer RPL on a third-party DR3). The window component WP may include a light-transmitting portion WTA and a light-blocking portion WBM.

[0047] The light-transmitting portion (WTA) may overlap with the display area (DA). The light-transmitting portion (WTA) may include glass and / or synthetic resin.

[0048] The light-blocking portion (WBM) can overlap with the non-display area (NDA). The light-blocking portion (WBM) can partially overlap with the light-transmitting portion (WTA). The light-blocking portion (WBM) can be positioned below the light-transmitting portion (WTA). The light-blocking portion (WBM) can be configured to block light emitted from the display panel (DP).

[0050] Figure 3 This is a plan view of a display panel DP according to an embodiment of the present disclosure.

[0051] Reference Figure 3 The display panel DP may have a display area DA and a non-display area NDA defined within the display panel DP. The non-display area NDA may (e.g., in a plan view) be defined around the display area DA. The display area DA may correspond to Figure 1 The display device DD shown has a display area DA. The non-display area NDA can correspond to... Figure 1 The non-display area NDA of the display device DD shown in the figure.

[0054] The input sensor integrated circuit (TIC) and the control integrated circuit (CIC) can be mounted in / on a flexible printed circuit board (FPCB) and configured to receive electrical signals from multiple pads (PD).

[0055] The input sensor integrated circuit (TIC) can use multiple pads (PD) to process signals corresponding to changes in current applied to the display area (DA) due to user touch or signals corresponding to external pressure applied via the input sensor unit (ISP).

[0056] The control integrated circuit (CIC) can be a circuit configured as at least one of a control data integrated circuit (DIC) and an input sensor integrated circuit (TIC).

[0057] The bendable area BA of the display panel DP can be bent.

[0058] Figure 4 This is an equivalent circuit diagram of pixel PX according to an embodiment of the present disclosure. Figure 5 Is applied to Figure 4 The timing diagram shows the light emission control signal Ei and the scanning signals Si-1, Si, and Si+1 of pixel PX. Figure 4The pixel PX is shown connected to the i-th scan line SLNi (also referred to as scan line SLNi in this paper) and the i-th emission control line ECLi (also referred to as emission control line ECLi in this paper).

[0059] A pixel PX may include an organic light-emitting diode (OLED) and a pixel circuit CC. In an embodiment, the pixel circuit CC may include a plurality of transistors T1 to T7 and a capacitor CP. The pixel circuit CC may be configured to control the amount of current flowing through the OLED in response to a data signal. Here, i is an integer greater than 1.

[0060] An organic light-emitting diode (OLED) can be configured to emit light with a selectable brightness corresponding to the amount of current supplied from the pixel circuitry CC. In an embodiment, the level of a first power ELVDD can be set to be higher than the level of a second power ELVSS.

[0061] Each of the transistors T1 to T7 may include an input electrode (e.g., a source electrode), an output electrode (e.g., a drain electrode), and a control electrode (e.g., a gate electrode). In this disclosure, for the sake of brevity, one of the input electrode and the output electrode may be referred to as the first electrode, and the other may be referred to as the second electrode.

[0062] The first electrode of the first transistor T1 is connected to the power line PL that transmits the first power ELVDD via the fifth transistor T5, and the second electrode is connected to the anode electrode of the organic light-emitting diode (OLED) via the sixth transistor T6. In this specification, the first transistor T1 may be referred to as the driving transistor.

[0063] The first transistor T1 is configured to control the amount of current flowing through the organic light-emitting diode (OLED) in response to a voltage applied to the control electrode.

[0064] The second transistor T2 is connected between the data line DL and the first electrode of the first transistor T1. Furthermore, the control electrode of the second transistor T2 is connected to the i-th scan line SLNi. When the i-th scan signal Si (also referred to herein as scan signal Si) is provided to the i-th scan line SLNi, the second transistor T2 is turned on to electrically connect the data line DL and the first electrode of the first transistor T1.

[0065] The third transistor T3 is connected between the second electrode and the control electrode of the first transistor T1. The control electrode of the third transistor T3 is connected to the i-th scan line SLNi. When the i-th scan signal Si is provided to the i-th scan line SLNi, the third transistor T3 is turned on to electrically connect the second electrode and the control electrode of the first transistor T1. Therefore, when the third transistor T3 is turned on, the first transistor T1 is connected in a diode manner.

[0066] The fourth transistor T4 is connected between node ND and the initialization power generation unit. Furthermore, the control electrode of the fourth transistor T4 is connected to the (i-1)th scan line SLNi-1. When the (i-1)th scan signal Si-1 (also referred to herein as scan signal Si-1) is provided to the (i-1)th scan line SLNi-1, the fourth transistor T4 is turned on to provide the initialization voltage Vint to node ND.

[0067] The fifth transistor T5 is connected between the power line PL and the first electrode of the first transistor T1. The control electrode of the fifth transistor T5 is connected to the i-th light-emitting control line ECLi.

[0068] The sixth transistor T6 is connected between the second electrode of the first transistor T1 and the anode electrode of the organic light-emitting diode (OLED). Furthermore, the control electrode of the sixth transistor T6 is connected to the i-th light-emitting control line ECLi.

[0069] The seventh transistor T7 is connected between the initialization power generation unit and the anode electrode of the organic light-emitting diode (OLED). Furthermore, the control electrode of the seventh transistor T7 is connected to the (i+1)th scan line SLNi+1. When the (i+1)th scan signal Si+1 is provided to the (i+1)th scan line SLNi+1, the seventh transistor T7 is turned on to provide the initialization voltage Vint to the anode electrode of the OLED.

[0070] The seventh transistor T7 can improve the black level performance of pixel PX. Specifically, when the seventh transistor T7 is turned on, the parasitic capacitor of the organic light-emitting diode (OLED) discharges. Then, when achieving black brightness, the OLED does not emit light due to the leakage current from the first transistor T1, and therefore, the black level performance can be improved.

[0071] In addition, Figure 4 In the diagram, the control electrode of the seventh transistor T7 is shown connected to the (i+1)th scan line SLNi+1, but embodiments of this disclosure are not limited to this configuration. In embodiments of the invention, the control electrode of the seventh transistor T7 may be connected to either the i-th scan line SLNi or the (i-1)th scan line SLNi-1.

[0072] Figure 4 The equivalent circuit diagram is based on P-type metal-oxide-semiconductor (PMOS) transistors, but embodiments of this disclosure are not limited to this configuration. In embodiments of the invention, the pixel PX may be composed of N-type metal-oxide-semiconductor (NMOS) transistors. In embodiments of this disclosure, the pixel PX may be composed of a combination of NMOS and PMOS transistors.

[0073] A capacitor CP is positioned between the power line PL and node ND. The capacitor CP is configured to store the voltage corresponding to the data signal. With the fifth transistor T5 and the sixth transistor T6 turned on, the amount of current flowing through the first transistor T1 can be determined based on the voltage stored in the capacitor CP.

[0074] In this disclosure, the structure of the pixel PX is not limited to Figure 4 The structure shown is illustrated. In embodiments of this disclosure, the pixel PX can be implemented in various ways to enable the organic light-emitting diode (OLED) to emit light.

[0075] Reference Figure 5 The light emission control signal Ei can be either high (E-HIGH) or low (E-LOW). The scan signals Si-1, Si, and Si+1 can each be either high (S-HIGH) or low (S-LOW).

[0076] When the light emission control signal Ei has a high level E-HIGH, the fifth transistor T5 and the sixth transistor T6 are turned off. When the fifth transistor T5 is turned off, the power line PL and the first electrode of the first transistor T1 are electrically disconnected. When the sixth transistor T6 is turned off, the second electrode of the first transistor T1 and the anode electrode of the organic light-emitting diode (OLED) are electrically disconnected. Therefore, when a light emission control signal Ei with a high level E-HIGH is provided to the i-th light emission control line ECLi, the organic light-emitting diode (OLED) does not emit light.

[0077] Subsequently, with the (i-1)th scan signal Si-1 supplied to the (i-1)th scan line SLNi-1 having a low level S-LOW, the fourth transistor T4 is turned on. With the fourth transistor T4 turned on, the initialization voltage Vint is supplied to node ND.

[0078] When the i-th scan signal Si supplied to the i-th scan line SLNi has a low level S-LOW, the second transistor T2 and the third transistor T3 are turned on.

[0079] With the second transistor T2 turned on, the data signal is supplied to the first electrode of the first transistor T1. Here, since node ND is initialized to the initialization voltage Vint, the first transistor T1 is turned on. With the first transistor T1 turned on, the voltage corresponding to the data signal is supplied to node ND. Here, capacitor CP stores the voltage corresponding to the data signal.

[0080] When the (i+1)th scan signal Si+1 provided to the (i+1)th scan line SLNi+1 has a low level S-LOW, the seventh transistor T7 is turned on.

[0081] With the seventh transistor T7 turned on, the initialization voltage Vint is provided to the anode electrode of the organic light-emitting diode (OLED), thereby discharging the parasitic capacitor of the OLED.

[0082] When the light emission control signal Ei supplied to the light emission control line ECLi is at a low level (E-LOW), the fifth transistor T5 and the sixth transistor T6 are turned on. With the fifth transistor T5 turned on, a first power supply ELVDD is supplied to the first electrode of the first transistor T1. When the sixth transistor T6 is turned on, the second electrode of the first transistor T1 is electrically connected to the anode electrode of the organic light-emitting diode (OLED). The OLED then generates light of a predetermined brightness in response to the amount of current supplied.

[0084] Reference Figure 6 In this embodiment, the display module DPM may include a display panel DP, an input sensor unit ISP, and a reflective protective layer RPL. The display panel DP may be... Figure 6 It is simply shown in the image.

[0085] In this embodiment, the display panel DP may include a circuit layer CL, a light-emitting diode layer ELL, and a packaging layer TFE. Light can be emitted from the display panel DP.

[0086] The circuit layer CL can be configured to transmit electrical signals. The electrical signals transmitted from the circuit layer CL can then be transmitted to the light-emitting diode layer ELL. The configuration of the circuit layer CL will be described in detail with reference to other accompanying drawings.

[0087] In one embodiment, the light-emitting diode layer ELL may include a pixel-defining film PDL and a plurality of light-emitting diodes (LDs). The light-emitting diode layer ELL may be disposed on the circuit layer CL. The light-emitting diode layer ELL may be configured to receive electrical signals from the circuit layer CL to emit light.

[0088] The pixel defining film (PDL) can be disposed on the circuit layer CL (e.g., directly disposed on the circuit layer CL on a third-party DR3). The PDL can have multiple light-emitting openings (LOPs) defined within it. Multiple light-emitting diodes (LDs) can be disposed in the multiple LOPs. The PDL can be configured to absorb incident light. In an embodiment, the light absorbed by the PDL can be light having a wavelength in the visible spectrum.

[0089] In embodiments, a plurality of light-emitting diodes (LDs) may include a first-color LD-R, a second-color LD-G, and a third-color LD-B. For example, the first color may be red, the second color may be green, and the third color may be blue. However, embodiments of this disclosure are not limited thereto, and the number of LDs and the color of the light emitted by the LDs may vary. The LDs may be disposed on a circuit layer CL. For example, in some embodiments, the first color may be any of the three primary colors, the second color may be any of the three primary colors other than the first color, and the third color may be any of the three primary colors other than the first and second colors.

[0090] At least some portions of each of a plurality of light-emitting diodes (LDs) can be disposed in a corresponding one of a plurality of light-emitting openings (LOPs). The plurality of light-emitting diodes (LDs) can be configured to emit light.

The third-color LD-B can be configured to emit light with a third wavelength different from the first and second wavelengths. The third wavelength can be in the range of approximately 450 nm to approximately 490 nm. The light with the third wavelength can be blue light.

[0094] For example, multiple light-emitting diodes (LDs) can be configured to emit light with different wavelengths from each other. In other words, multiple LDs can comprise different types of light-emitting materials. Furthermore, the specific structures of the multiple LDs can differ from each other. For example, the thicknesses of the multiple LDs (e.g., the thickness on the third-direction DR3) can differ from each other.

[0095] However, the layer structure of each of the multiple light-emitting diodes (LDs) can be identical. For example, each of the multiple LDs can include an anode electrode, a hole-functional layer, a light-emitting layer, an electron-functional layer, and a cathode electrode. The configuration of the multiple LDs will be described in detail with reference to other accompanying drawings.

[0096] A TFE (Transmission over Expansion) layer can be disposed on multiple LEDs (LDs). The TFE layer can cover multiple LEDs (LDs). The TFE layer can be configured to seal multiple LEDs (LDs) and protect them from external oxygen or moisture.

[0098] The lower input sensor insulating layer (LDL) can be disposed on the encapsulation layer TFE (e.g., directly disposed on the encapsulation layer TFE on the third-party DR3). The lower input sensor insulating layer (LDL) can be configured to protect the encapsulation layer TFE from external impacts. The lower input sensor insulating layer (LDL) can have a single-layer or multi-layer structure and include inorganic or composite materials. In embodiments, the inorganic material may include at least one of alumina, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide. In one or more embodiments, the lower input sensor insulating layer (LDL) can be replaced with an organic insulating layer. Furthermore, in some embodiments, the lower input sensor insulating layer (LDL) may not be provided.

[0099] The lower sensor electrode LSP can be disposed on the lower input sensor insulating layer LDL (e.g., directly disposed on the lower input sensor insulating layer LDL on the third-party DR3). The lower sensor electrode LSP may include a metal layer or a transparent electrode. In embodiments, the metal layer may include molybdenum, silver, titanium, copper, aluminum, and alloys thereof. In embodiments, the transparent electrode may include a transparent conductive oxide such as ITO (indium tin oxide), IZO (indium zinc oxide), ZnO (zinc oxide), or ITZO (indium tin zinc oxide).

[0100] The intermediate input sensor insulating layer MDL can be disposed on the lower sensor electrode LSP (e.g., directly disposed on the lower sensor electrode LSP). The intermediate input sensor insulating layer MDL can cover both the lower input sensor insulating layer LDL and the lower sensor electrode LSP. The intermediate input sensor insulating layer MDL can have a single-layer or multi-layer structure and comprises inorganic or composite materials. In one or more embodiments, the intermediate input sensor insulating layer MDL can be replaced with an organic insulating layer.

[0101] The upper sensor electrode USP can be disposed on the intermediate input sensor insulating layer MDL (e.g., directly disposed on the intermediate input sensor insulating layer MDL). The detailed configuration of the upper sensor electrode USP can be the same as the detailed configuration of the lower sensor electrode LSP. At least some of the upper sensor electrodes USP can overlap with the lower sensor electrode LSP. The upper sensor electrode USP can be electrically connected to the lower sensor electrode LSP.

[0102] The upper input sensor insulating layer UDL may cover the intermediate input sensor insulating layer MDL and the upper sensor electrode USP. The upper input sensor insulating layer UDL may have a single-layer structure or a multi-layer structure and may comprise inorganic or composite materials. In one or more embodiments, the upper input sensor insulating layer UDL may be replaced with an organic insulating layer.

[0103] In an embodiment, the reflective protective layer RPL may include a light-blocking film LBL, multiple diffraction-reducing portions DRP, multiple color filters CF, and an upper coating OC. The reflective protective layer RPL may be configured to prevent external light from being reflected from the display module DPM.

[0104] A light-blocking film (LBL) can be disposed on the input sensor unit (ISP). The LBL can overlap with a pixel-defining film (PDL) (e.g., on a third-party DR3). The LBL can have multiple transmission openings (POPs) defined within it. The LBL can include a light-absorbing material. The LBL can be configured to absorb incident light. The light absorbed by the LBL can be light with wavelengths in the visible spectrum.

[0105] In an embodiment, the plurality of transmission aperture POPs may include a first color transmission aperture POP-R, a second color transmission aperture POP-G, and a third color transmission aperture POP-B. The plurality of transmission aperture POPs may overlap with a plurality of light-emitting diodes (LDs) in a planar view (e.g., on a third-direction DR3). The plurality of transmission aperture POPs may also overlap with a plurality of light-emitting apertures (LOPs) in a planar view (e.g., on a third-direction DR3). In other words, each of the plurality of light-emitting apertures (LOPs) may overlap with its corresponding transmission aperture POP in a planar view (e.g., on a third-direction DR3).

[0106] Multiple transmission aperture POPs can be arranged regularly along a pattern. Therefore, light transmitted through multiple transmission aperture POPs may be diffracted.

[0107] The first color transmission aperture POP-R can overlap with the first color light-emitting diode LD-R (e.g., on the third-direction DR3). The first color transmission aperture POP-R can overlap with the light-emitting aperture LOP on which the first color light-emitting diode LD-R is disposed.

[0108] The second color transmission aperture POP-G can overlap with the second color light-emitting diode LD-G (e.g., on the third-direction DR3). The second color transmission aperture POP-G can overlap with the light-emitting aperture LOP on which the second color light-emitting diode LD-G is provided.

[0109] The third color transmission aperture POP-B can (e.g., on the third-direction DR3) overlap with the third color light-emitting diode LD-B. The third color transmission aperture POP-B can overlap with the light-emitting aperture LOP on which the third color light-emitting diode LD-B is located.

[0110] The aperture center COP can be defined in each of the plurality of transmission apertures POP. For each of the plurality of transmission apertures POP, the aperture center COP can be a geometric centroid (e.g., a centroid in a planar view) defined on a plane defined by a first direction DR1 and a second direction DR2.

[0111] In an embodiment, the plurality of diffraction reduction portions (DRPs) may include a first color diffraction reduction portion (DRP-R), a second color diffraction reduction portion (DRP-G), and a third color diffraction reduction portion (DRP-B). The plurality of diffraction reduction portions (DRPs) may be disposed in the plurality of transmission openings (POPs). The plurality of diffraction reduction portions (DRPs) may (e.g., on a third-direction DR3) not overlap with the light-blocking film (LBL).

[0112] Multiple diffraction reduction portions (DRPs) may include a light-absorbing material. In an embodiment, the material included in the multiple diffraction reduction portions (DRPs) may be the same as the material included in the light-blocking film (LBL). For example, the light-blocking film (LBL) may include the same material as the first color diffraction reduction portion (DRP-R). The multiple diffraction reduction portions (DRPs) may be configured to absorb incident light. The multiple diffraction reduction portions (DRPs) may be irregularly arranged. The multiple diffraction reduction portions (DRPs) may be configured to reduce diffraction phenomena caused by multiple regularly arranged transmission openings (POPs).

[0113] Multiple diffraction reduction portions (DRPs) may each have a diffraction reduction center (COD) defined therein. For each of the multiple diffraction reduction portions (DRPs), the diffraction reduction center (COD) may be a geometric centroid defined on a plane defined by a first direction DR1 and a second direction DR2.

[0114] In a plane, the diffraction reduction center (COD) and the corresponding aperture center (COP) can be spaced apart from each other. The diffraction reduction center (COD) and the corresponding aperture center (COP) can (e.g., in a planar view) not overlap. When the diffraction reduction center (COD) and the corresponding aperture center (COP) are spaced apart, the amount of diffraction pattern formed by light transmitted through the transmission aperture (POP) can be further reduced. Therefore, the diffraction pattern of light transmitted through the transmission aperture (POP) can be less noticeable.

[0115] The first color diffraction reduction portion DRP-R can be disposed in the first color transmission aperture POP-R. The center COD of the diffraction reduction portion defined in the first color diffraction reduction portion DRP-R and the center COP of the aperture defined in the first color transmission aperture POP-R can be spaced apart from each other (e.g., in a plan view).

[0116] The second color diffraction reduction portion DRP-G can be disposed in the second color transmission aperture POP-G. The center COD of the diffraction reduction portion defined in the second color diffraction reduction portion DRP-G and the center COP of the aperture defined in the second color transmission aperture POP-G can be spaced apart from each other (e.g., in a plan view).

[0117] The third color diffraction reduction portion DRP-B can be disposed within the third color transmission aperture POP-B. The center COD of the diffraction reduction portion defined in the third color diffraction reduction portion DRP-B and the center COP of the aperture defined in the third color transmission aperture POP-B can be spaced apart from each other (e.g., in a plan view).

[0118] Multiple color filters (CFs) may include a first color filter (CF-R), a second color filter (CF-G), and a third color filter (CF-B). The multiple color filters (CFs) may (e.g., on a third-direction DR3) overlap with multiple light-emitting diodes (LDs). The multiple color filters (CFs) may be disposed within multiple transmission apertures (POPs). The multiple color filters (CFs) may cover multiple diffraction reduction sections (DRPs). The multiple color filters (CFs) may be configured to transmit or block incident light according to the wavelength of the incident light.

[0119] A first color filter CF-R can (e.g., on a third-direction DR3) overlap with a first color light-emitting diode LD-R. The first color filter CF-R can be disposed within a first color transmission aperture POP-R. The first color filter CF-R can cover a first color diffraction reduction portion DRP-R. The first color filter CF-R can be configured to allow transmission of light of a first wavelength in the incident light. The first color filter CF-R can be configured to block light of a second wavelength and light of a third wavelength in the incident light.

[0120] The second color filter CF-G can (e.g., on the third-direction DR3) overlap with the second-color light-emitting diode LD-G. The second color filter CF-G can be disposed within the second-color transmission aperture POP-G. The second color filter CF-G can cover the second-color diffraction reduction portion DRP-G. The second color filter CF-G can be configured to allow the transmission of light with a second wavelength in the incident light. The second color filter CF-G can also be configured to block light with a first wavelength and light with a third wavelength in the incident light.

[0121] The third color filter CF-B can (e.g., on the third-direction DR3) overlap with the third-color light-emitting diode LD-B. The third color filter CF-B can be positioned within the third-color transmission aperture POP-B. The third color filter CF-B can cover the third-color diffraction reduction portion DRP-B. The third color filter CF-B can be configured to allow the transmission of light with a third wavelength in the incident light. The third color filter CF-B can also be configured to block light with a first wavelength and light with a second wavelength in the incident light.

[0122] The top coating OC can be disposed on multiple color filters CF (e.g., directly on multiple color filters CF). The top coating OC can be configured to protect multiple color filters CF. In embodiments, the top coating OC may include an organic material. For example, the top coating OC may include an acrylic polymer.

[0123] Figure 7 yes Figure 6A more detailed view of some configurations in the enlarged view of area AA shown.

[0124] Reference Figure 7 In this embodiment, the display module DPM (see...) Figure 6 This may include a display panel (DP), an input sensor unit (ISP), and a reflective protective layer (RPL). Figure 7 In the middle, the circuit layer CL, the first color light-emitting diode LD-R, and the encapsulation layer TFE can be Figure 7 It is shown in detail in the text.

[0125] In an embodiment, the circuit layer CL may include a substrate component BL, a barrier layer BR, a buffer layer BF, a gate insulating layer GI, an interlayer insulating layer ILD, a circuit insulating layer VIA, a first transistor T1, and a second transistor T2.

[0126] The first transistor T1 and the second transistor T2 can be configured to transmit electrical signals. Furthermore, the first transistor T1 and the second transistor T2 can each include an active portion ACL, a first electrode ED1, a control electrode GE, and a second electrode ED2.

[0127] The substrate component BL can be the substrate layer of the circuit layer CL. For example, other components of the circuit layer CL can be stacked on the substrate component BL. The substrate component BL can include organic layers and / or inorganic layers. The organic layers can include organic materials. For example, in this embodiment, polyimide can be included. The inorganic layers can include inorganic materials.

[0128] The barrier layer BR can be disposed on the substrate member BL (e.g., directly disposed on the substrate member BL on a third-direction DR3). The barrier layer BR can be configured to prevent the penetration of moisture introduced from the outside. In embodiments, the barrier layer BR may comprise an inorganic insulating material such as silicon oxide and silicon nitride.

[0129] A buffer layer BF can be disposed on the barrier layer BR (e.g., directly on the barrier layer BR on a third-party DR3). The buffer layer BF can be configured to prevent the upward propagation of impurities introduced from the bottom. Therefore, components disposed on the buffer layer BF can be protected. In embodiments, the buffer layer BF may comprise inorganic insulating materials such as silicon oxide and silicon nitride.

[0130] Multiple active portion ACLs can be disposed on the buffer layer BF (e.g., directly disposed on the buffer layer BF on a third-direction DR3). In embodiments, the multiple active portion ACLs may include polycrystalline silicon or amorphous silicon. In addition to the above, the multiple active portion ACLs may include metal-oxide-semiconductor. The active portion ACL may include a channel region serving as a channel through which electrons or holes can move, and a first ion-doped region and a second ion-doped region disposed therebetween.

[0131] The gate insulating layer GI may cover the buffer layer BF and multiple active portions ACL. The gate insulating layer GI may include organic films and / or inorganic films. The gate insulating layer GI may include multiple inorganic thin films. In an embodiment, the multiple inorganic thin films may include a silicon nitride layer and a silicon oxide layer.

[0132] Multiple control electrodes GE can be disposed on the gate insulating layer GI (e.g., directly disposed on the gate insulating layer GI on a third-direction DR3). The multiple control electrodes GE can overlap with multiple active portions ACL. Furthermore, in embodiments, the multiple control electrodes GE may include molybdenum (Mo).

[0133] The interlayer insulating layer (ILD) can cover the gate insulating layer (GI) and multiple control electrodes (GE). The ILD can include organic and / or inorganic films. The ILD can also include multiple inorganic or organic thin films. In an embodiment, the multiple inorganic thin films can include silicon nitride and silicon oxide films.

[0134] Multiple first electrodes ED1 and multiple second electrodes ED2 may be disposed on the interlayer insulating layer (ILD) (e.g., directly disposed on the interlayer insulating layer ILD on a third-party DR3). In embodiments, the multiple first electrodes ED1 and multiple second electrodes ED2 may be electrically connected to multiple active portions ACL through multiple contact holes defined in the interlayer insulating layer ILD. Furthermore, the multiple first electrodes ED1 and multiple second electrodes ED2 may include metal.

[0135] The circuit insulating layer VIA may cover the interlayer insulating layer ILD, multiple first electrodes ED1, and multiple second electrodes ED2. The circuit insulating layer VIA may include an organic film and / or an inorganic film. In some embodiments, the circuit insulating layer VIA may provide a flat surface. However, in some embodiments, the number of circuit insulating layers VIA may be increased as needed, and a flat surface may not be provided.

[0136] A first-color light-emitting diode (LD-R) may include an anode electrode AE, a hole-functional layer HFL, a light-emitting layer EML, an electron-functional layer EFL, and a cathode electrode CE. In one or more embodiments, Figure 6The second color LED LD-G and the third color LED LD-B shown can have the same layer structure as the first color LED LD-R.

[0137] The anode electrode AE ​​can be disposed on a portion of the circuit insulating layer VIA (e.g., directly disposed on a portion of the circuit insulating layer VIA on a third-party DR3). Specifically, the anode electrode AE ​​can be exposed by a plurality of light-emitting openings LOP. Furthermore, the anode electrode AE ​​can be electrically connected to a corresponding one of a plurality of second electrodes ED2 through contact holes defined in the circuit insulating layer VIA. Therefore, the anode electrode AE ​​can be configured to receive electrical signals from the first transistor T1 and the second transistor T2.

[0138] although Figure 7 The first transistor T1 and the second transistor T2 are shown, but their structures are not necessarily limited to these. Although Figure 7 It is shown as if the first transistor T1 is in direct contact with the anode electrode AE ​​through a corresponding one of the plurality of second electrodes ED2, but this is due to the cross-sectional view, and in reality, the first transistor T1 can be connected to the anode electrode AE ​​through another transistor. However, embodiments of this disclosure are not limited to this, and in embodiments of this disclosure, the first transistor T1 can be in direct contact with the anode electrode AE ​​through a corresponding one of the plurality of second electrodes ED2.

[0139] The hole functional layer (HFL) can be disposed on the anode electrode AE ​​(e.g., directly on the anode electrode AE ​​on a third-party DR3). The hole functional layer (HFL) can be configured to support the transport of holes generated from the anode electrode AE. For example, in an embodiment, the hole functional layer (HFL) can be configured to more easily receive holes injected from the anode electrode AE ​​and facilitate hole transport. The hole functional layer (HFL) can have a multi-layer structure. For example, the hole functional layer (HFL) may include a hole injection layer and a hole transport layer.

[0140] The light-emitting layer (EML) can be disposed on the hole functional layer (HFL) (e.g., directly disposed on the HFL). The EML can emit light. In embodiments, the EML may include, for example, organic light-emitting materials or quantum dots. Therefore, a light-emitting diode (LD) (see...) Figure 6 ) can be an organic light-emitting diode (e.g., Figure 4 The organic light-emitting diode (OLED) or quantum dot light-emitting diode shown is illustrated.

[0141] The electronic functional layer (EFL) can be disposed on the light-emitting layer (EML) (e.g., directly on the EML). The EFL can be configured to support the transport of electrons generated from the cathode electrode (CE). For example, the EFL can be configured to more easily receive electrons injected from the cathode electrode (CE) and facilitate electron transport. The EFL can have a multilayer structure. For example, in some embodiments, the EFL may include an electron injection layer and an electron transport layer.

[0142] The cathode electrode CE can be disposed on the electronic functional layer EFL (e.g., directly disposed on the electronic functional layer EFL). The cathode electrode CE has low resistance, and therefore current can flow easily. The cathode electrode CE can be a shared electrode. Therefore, in some embodiments, Figure 6 The multiple light-emitting diodes LD-R, LD-G, and LD-B shown can share a common cathode electrode CE.

[0143] In an embodiment, the encapsulation layer TFE may include a first encapsulation inorganic layer CVD1, an encapsulation organic layer MN, and a second encapsulation inorganic layer CVD2. Although Figure 7 The encapsulation layer TFE in the diagram is shown as comprising two encapsulation inorganic layers CVD1 and CVD2 and one encapsulation organic layer MN, but embodiments of this disclosure are not limited to this configuration. For example, in some embodiments, the encapsulation layer TFE may comprise three inorganic encapsulation layers and two organic encapsulation layers, in which case the inorganic and organic encapsulation layers may be alternately stacked (e.g., on a third-direction DR3).

[0144] exist Figure 7 The aperture width OPW and the spacing distance SD can be further illustrated. The aperture width OPW can be defined as the width of the first color transmission aperture POP-R (e.g., the width in a plan view). The spacing distance SD can be defined as the distance in a plan view between the aperture center COP and the diffraction reduction portion center COD. In embodiments, the spacing distance SD can be in the range of about 0.02 times to about 0.32 times the size of the aperture width OPW. When the spacing distance SD is smaller than about 0.02 times the size of the aperture width OPW, the effect of the first color diffraction reduction portion DRP-R in reducing diffraction may be limited. When the spacing distance SD is larger than about 0.32 times the aperture width OPW, at least some of the first color diffraction reduction portions DRP-R may not be provided in the first color transmission aperture POP-R.

[0145] Although for the sake of simplifying the illustration, Figure 7 Only the aperture width OPW of the first color transmission aperture POP-R, the first color diffraction reduction portion DRP-R, and the spacing distance SD are shown, but for Figure 6The second color transmission aperture POP-G and the second color diffraction reduction portion DRP-G shown in the diagram can be similarly defined in terms of aperture width OPW and spacing distance SD. Furthermore, for Figure 6 The third color transmission aperture POP-B and the third color diffraction reduction portion DRP-B shown in the figure, the aperture width OPW and the spacing distance SD can be similarly defined.

[0146] Figure 8 It is a plan view of any one of a plurality of pixel PX according to embodiments of the present disclosure.

[0147] Reference Figure 8 In an embodiment, pixel PX may include a first color sub-pixel SPX-R, a second color sub-pixel SPX-G, and two third color sub-pixels SPX-B. Figure 8 The diagram may show multiple transmission apertures (POPs) and multiple diffraction reduction portions (DRPs). Pixels (PX) may extend from a first pixel distance (DPD1) in a first direction (DR1) and from a second pixel distance (DPD2) in a second direction (DR2).

[0148] The first color subpixel SPX-R may be defined by a first color transmission aperture POP-R. The first color subpixel SPX-R may be configured to emit light having a first wavelength. The centroid of the first color transmission aperture POP-R may be shown as (e.g., defined as) the aperture center COP, and the centroid of the first color diffraction reduction portion DRP-R may be shown as (e.g., defined as) the diffraction reduction portion center COD.

[0149] In the planar diagram, the centroid of the first color diffraction reduction portion DRP-R can be spaced apart from the centroid of the first color transmission opening POP-R. The centroid of the first color diffraction reduction portion DRP-R can be spaced apart from the centroid of the first color transmission opening POP-R by a first color spacing distance in the first color spacing direction.

[0150] In a planar diagram, the value obtained by dividing the area of ​​the first color diffraction reduction portion DRP-R by the area of ​​the first color transmission opening POP-R can be defined as the first color area ratio. In embodiments, the first color area ratio can be in the range of about 0.05 to about 0.20. When the first color area ratio is less than about 0.05, the effect of the first color diffraction reduction portion DRP-R in reducing diffraction may be limited. When the first color area ratio is greater than about 0.20, light with the first wavelength may be absorbed by the first color diffraction reduction portion DRP-R, and the luminous efficiency of light with the first wavelength may decrease.

[0151] The second color subpixel SPX-G may be defined by a second color transmission aperture POP-G. The second color subpixel SPX-G may be configured to emit light having a second wavelength. The centroid of the second color transmission aperture POP-G may be shown as (e.g., defined as) the aperture center COP, and the centroid of the second color diffraction reduction portion DRP-G may be shown as (e.g., defined as) the diffraction reduction portion center COD.

[0152] In the plan view, the centroid of the second color diffraction reduction portion DRP-G can be spaced apart from the centroid of the second color transmission opening POP-G. The centroid of the second color diffraction reduction portion DRP-G can be spaced apart from the centroid of the second color transmission opening POP-G by a second color spacing distance in the second color spacing direction. In an embodiment, the second color spacing direction can be different from the first color spacing direction. In an embodiment, the second color spacing distance can be different from the first color spacing distance.

[0153] In a planar diagram, the value obtained by dividing the area of ​​the second-color diffraction reduction portion DRP-G by the area of ​​the second-color transmission opening POP-G can be defined as the second-color area ratio. In embodiments, the second-color area ratio can be in the range of about 0.05 to about 0.20. When the second-color area ratio is less than about 0.05, the effect of the second-color diffraction reduction portion DRP-G in reducing diffraction may be limited. When the second-color area ratio is greater than about 0.20, light with a second wavelength may be absorbed by the second-color diffraction reduction portion DRP-G, and the luminous efficiency of light with a second wavelength may decrease. The second-color area ratio and the first-color area ratio can be substantially the same.

[0154] Multiple third-color subpixels SPX-B can be defined by multiple third-color transmission apertures POP-B. The multiple third-color subpixels SPX-B can be configured to emit light having a third wavelength. The centroid of each of the multiple third-color transmission apertures POP-B can be shown as (e.g., defined as) the aperture center COP, and the centroid of each of the multiple third-color diffraction reduction portions DRP-B can be shown as (e.g., defined as) the diffraction reduction portion center COD.

[0155] In the planar view, the centroid of each of the plurality of third-color diffraction reduction portions DRP-B can be spaced apart from the centroid of the corresponding third-color transmission aperture POP-B. The centroid of each of the plurality of third-color diffraction reduction portions DRP-B can be spaced apart from the centroid of the corresponding third-color transmission aperture POP-B by a third-color spacing distance in the third-color spacing direction. In an embodiment, the third-color spacing direction can be different from the first-color spacing direction and the second-color spacing direction. In an embodiment, the third-color spacing distance can be different from the first-color spacing distance and the second-color spacing distance.

[0156] The third color spacing direction and third color spacing distance of any one of the multiple third color diffraction reduction portions DRP-B may be different from those of the other multiple third color diffraction reduction portions DRP-B.

[0157] In a planar diagram, the value obtained by dividing the area of ​​each of the plurality of third-color diffraction reduction portions DRP-B by the area of ​​the corresponding third-color transmission opening POP-B can be defined as the third-color area ratio. In embodiments, the third-color area ratio can be in the range of about 0.05 to about 0.20. When the third-color area ratio is less than about 0.05, the effect of the third-color diffraction reduction portion DRP-B in reducing diffraction may be limited. When the third-color area ratio is greater than about 0.20, light with a third wavelength may be absorbed by the third-color diffraction reduction portion DRP-B, and the luminous efficiency of light with a third wavelength may be reduced. In embodiments, the third-color area ratio can be less than the first-color area ratio and the second-color area ratio.

[0158] As a result, the centroids of multiple diffraction reduction portions (DRPs) located within a pixel PX can be spaced apart from the centroids of their respective corresponding transmission apertures (POPs) by different distances in different directions. Therefore, the multiple diffraction reduction portions (DRPs) can be irregularly arranged, and diffraction phenomena can be reduced.

[0159] exist Figure 8 middle, Figure 8 The plurality of transmission apertures (POPs) and the plurality of diffraction reduction portions (DRPs) shown are each illustrated as having a circular shape (e.g., in a plan view). However, the shape of each of the plurality of transmission apertures (POPs) and the plurality of diffraction reduction portions (DRPs) is not limited to this. The plurality of transmission apertures (POPs) and the plurality of diffraction reduction portions (DRPs) may each have a polygonal shape (e.g., rectangular, trapezoidal, etc.) in a plan view.

[0160] Figure 8The diagram shows that pixel PX includes a first color subpixel SPX-R, a second color subpixel SPX-G, and two third color subpixels SPX-B, but the configuration of pixel PX is not limited to this.

[0161] Figure 9A This is a plan view of the display module DPM according to an embodiment of the present disclosure. Figure 9B yes Figure 9A The enlarged view of area BB shown.

[0162] Reference Figure 9A and Figure 9B Multiple pixels PX are disposed in the display module DPM. The multiple pixels PX can be arranged at a first pixel distance DPD1 along a first direction DR1 and at a second pixel distance DPD2 along a second direction DR2. In an embodiment, the multiple pixels PX may include a first pixel PX1, a second pixel PX2, and a third pixel PX3. However, embodiments of this disclosure are not limited thereto, and the number of pixels can vary.

[0163] Multiple pixels PX may each have multiple transmission openings POP1, POP2, POP3 defined within the multiple pixels PX. In an embodiment, the multiple transmission openings POP1, POP2, POP3 defined in each of the multiple pixels PX may be defined along a predetermined pattern. Therefore, the shape of the multiple transmission openings POP1, POP2, POP3 defined in any one of the multiple pixels PX may be the same as the shape of the multiple transmission openings POP1, POP2, POP3 defined in another of the multiple pixels PX.

[0164] Multiple diffraction reduction portions DRP1, DRP2, and DRP3 can be disposed in each of the multiple pixels PX. In an embodiment, the multiple diffraction reduction portions DRP1, DRP2, and DRP3 disposed in each of the multiple pixels PX may not be arranged along a pattern. The multiple diffraction reduction portions DRP1, DRP2, and DRP3 disposed in any one of the multiple pixels PX may have different shapes than the multiple diffraction reduction portions DRP1, DRP2, and DRP3 disposed in another of the multiple pixels PX.

[0165] As described herein, the expression "shape of a plurality of elements" can have the concept of including the shape of each of the plurality of elements (e.g., shape in a plan view) and the positional relationship between the plurality of elements (e.g., positional relationship in a plan view). For example, in the case of comparing "a plurality of first elements" and "a plurality of second elements" in terms of shape, and if the shape of each of the plurality of first elements and the shape of each of the plurality of second elements (e.g., in a plan view) are the same as each other, and the positional relationship between the plurality of first elements and the positional relationship between the plurality of second elements (e.g., in a plan view) are the same as each other, then the plurality of first elements and the plurality of second elements can be determined to have the same shape as each other.

[0166] A plurality of first transmission openings POP1 can be defined within a first pixel PX1. In an embodiment, the plurality of first transmission openings POP1 may include a first first color transmission opening POP1-R, a first second color transmission opening POP1-G, and a plurality of first third color transmission openings POP1-B. In this disclosure, the first transmission opening POP1 can be any one of the first first color transmission opening POP1-R, the first second color transmission opening POP1-G, and the plurality of first third color transmission openings POP1-B.

[0167] A plurality of second transmission openings POP2 may be defined within a second pixel PX2. In an embodiment, the plurality of second transmission openings POP2 may include a second first color transmission opening POP2-R, a second second color transmission opening POP2-G, and a plurality of second third color transmission openings POP2-B. In this disclosure, the second transmission openings POP2 may be any one of the second first color transmission opening POP2-R, the second second color transmission opening POP2-G, and the plurality of second third color transmission openings POP2-B.

[0168] The second pixel PX2 can be spaced apart from the first pixel PX1 in the first direction DR1. The centroid of each of the plurality of second transmission openings POP2 can be spaced apart from the centroid of the corresponding first transmission opening POP1 in the first arrangement direction by a first arrangement distance. In an embodiment, the first arrangement direction can be the first direction DR1. The first arrangement distance can be the first pixel distance DPD1.

[0169] In this embodiment, the centroid of the second first-color transmission opening POP2-R can be spaced apart from the centroid of the first first-color transmission opening POP1-R by a first arrangement distance in the first arrangement direction. The centroid of the second second-color transmission opening POP2-G can be spaced apart from the centroid of the first second-color transmission opening POP1-G by a first arrangement distance in the first arrangement direction. The centroid of each of the plurality of second third-color transmission openings POP2-B can be spaced apart from the centroid of the corresponding first third-color transmission opening POP1-B in the plurality of first third-color transmission openings POP1-B by a first arrangement distance in the first arrangement direction.

[0170] Therefore, the plurality of second transmission openings POP2 can be defined as being parallel to the plurality of first transmission openings POP1 by a first arrangement distance in the first arrangement direction. As a result, the shape of the plurality of second transmission openings POP2 defined in the second pixel PX2 can be the same as the shape of the plurality of first transmission openings POP1 defined in the first pixel PX1.

[0171] Multiple third transmission openings POP3 can be defined within a third pixel PX3. In embodiments, the multiple third transmission openings POP3 may include a third first color transmission opening POP3-R, a third second color transmission opening POP3-G, and multiple third third color transmission openings POP3-B. In this disclosure, the third transmission opening POP3 can be any one of the third first color transmission opening POP3-R, the third second color transmission opening POP3-G, and the multiple third third color transmission openings POP3-B.

[0172] The third pixel PX3 can be a pixel spaced apart from the first pixel PX1 in the second direction DR2. The centroid of each of the plurality of third transmission openings POP3 can be spaced apart from the centroid of the corresponding first transmission opening POP1 in the second arrangement direction by a second arrangement distance. In an embodiment, the second arrangement direction can be the second direction DR2. The second arrangement distance can be the second pixel distance DPD2.

[0173] In this embodiment, the centroid of the third first-color transmission opening POP3-R can be spaced apart from the centroid of the first first-color transmission opening POP1-R by a second arrangement distance in the second arrangement direction. The centroid of the third second-color transmission opening POP3-G can be spaced apart from the centroid of the first second-color transmission opening POP1-G by a second arrangement distance in the second arrangement direction. The centroid of each of the plurality of third third-color transmission openings POP3-B can be spaced apart from the centroid of the corresponding first third-color transmission opening POP1-B in the plurality of first third-color transmission openings POP1-B by a second arrangement distance in the second arrangement direction.

[0174] Therefore, the plurality of third transmission openings POP3 can be defined as being parallel to the plurality of first transmission openings POP1 by a second arrangement distance in the second arrangement direction. The shape of the plurality of third transmission openings POP3 defined in the third pixel PX3 can be the same as the shape of the plurality of first transmission openings POP1 defined in the first pixel PX1.

[0175] Multiple first diffraction reduction portions DRP1 can be disposed in the first pixel PX1. In an embodiment, the multiple first diffraction reduction portions DRP1 may include a first first color diffraction reduction portion DRP1-R, a first second color diffraction reduction portion DRP1-G, and multiple first third color diffraction reduction portions DRP1-B. In this disclosure, the first diffraction reduction portion DRP1 can be any one of the first first color diffraction reduction portion DRP1-R, the first second color diffraction reduction portion DRP1-G, and the multiple first third color diffraction reduction portions DRP1-B.

[0176] Multiple second diffraction reduction portions DRP2 can be disposed in the second pixel PX2. In an embodiment, the multiple second diffraction reduction portions DRP2 may include a second first color diffraction reduction portion DRP2-R, a second second color diffraction reduction portion DRP2-G, and multiple second third color diffraction reduction portions DRP2-B. In this disclosure, the second diffraction reduction portion DRP2 can be any one of the second first color diffraction reduction portion DRP2-R, the second second color diffraction reduction portion DRP2-G, and the multiple second third color diffraction reduction portions DRP2-B.

[0177] The second pixel PX2 can be a pixel spaced apart from the first pixel PX1 in the first direction DR1. In an embodiment, the centroid of each of the plurality of second diffraction reduction portions DRP2 can be spaced apart from the centroid of the corresponding first diffraction reduction portion DRP1 in a direction different from the first arrangement direction by a distance different from the first arrangement distance.

[0178] For example, in an embodiment, the centroid of the second first color diffraction reduction portion DRP2-R can be spaced apart from the centroid of the first first color diffraction reduction portion DRP1-R by a distance different from the first arrangement distance in a direction different from the first arrangement direction. Similarly, the centroid of the second second color diffraction reduction portion DRP2-G can be spaced apart from the centroid of the first second color diffraction reduction portion DRP1-G by a distance different from the first arrangement distance in a direction different from the first arrangement direction. The centroid of each of the plurality of second third color diffraction reduction portions DRP2-B can be spaced apart from the centroid of the corresponding first third color diffraction reduction portion DRP1-B in a direction different from the first arrangement direction by a distance different from the first arrangement distance.

[0179] Therefore, each of the multiple second diffraction reduction portions DRP2 can be configured to be shifted from the corresponding first diffraction reduction portion DRP1 among the multiple first diffraction reduction portions DRP1 by a distance different from the first arrangement distance in a direction different from the first arrangement direction. As a result, the multiple second diffraction reduction portions DRP2 disposed in the second pixel PX2 can have different shapes than the multiple first diffraction reduction portions DRP1 disposed in the first pixel PX1.

[0180] Multiple third diffraction reduction portions DRP3 can be defined within a third pixel PX3. In embodiments, the multiple third diffraction reduction portions DRP3 may include a third first color diffraction reduction portion DRP3-R, a third second color diffraction reduction portion DRP3-G, and multiple third third color diffraction reduction portions DRP3-B. In this disclosure, the third diffraction reduction portion DRP3 can be any one of the third first color diffraction reduction portion DRP3-R, the third second color diffraction reduction portion DRP3-G, and the multiple third third color diffraction reduction portions DRP3-B.

[0181] The third pixel PX3 can be a pixel spaced apart from the first pixel PX1 in the second direction DR2. The centroid of each of the plurality of third diffraction reduction portions DRP3 can be spaced apart from the centroid of the corresponding first diffraction reduction portion DRP1 in the plurality of first diffraction reduction portions DRP1 by a distance different from the second arrangement distance in a direction different from the second arrangement direction.

[0182] For example, in an embodiment, the centroid of the third first color diffraction reduction portion DRP3-R can be spaced apart from the centroid of the first first color diffraction reduction portion DRP1-R by a distance different from the second arrangement distance in a direction different from the second arrangement direction. Similarly, the centroid of the third second color diffraction reduction portion DRP3-G can be spaced apart from the centroid of the first second color diffraction reduction portion DRP1-G by a distance different from the second arrangement distance in a direction different from the second arrangement direction. The centroid of each of the plurality of third third color diffraction reduction portions DRP3-B can be spaced apart from the centroid of the corresponding first third color diffraction reduction portion DRP1-B in a direction different from the second arrangement direction by a distance different from the second arrangement distance.

[0183] Therefore, each of the plurality of third diffraction reduction portions DRP3 can be configured to be shifted from the corresponding first diffraction reduction portion DRP1 among the plurality of first diffraction reduction portions DRP1 by a distance different from the second arrangement distance in a direction different from the second arrangement direction. As a result, the plurality of third diffraction reduction portions DRP3 disposed in the third pixel PX3 can have different shapes than the plurality of first diffraction reduction portions DRP1 disposed in the first pixel PX1.

[0184] As a result, multiple pixels PX can have different shapes by reducing portions of DRP1, DRP2, and DRP3 through multiple diffractions. Consequently, the diffraction pattern generated by the multiple pixels PX can be reduced by reducing portions of DRP1, DRP2, and DRP3 through multiple diffractions.

[0185] However, in the comparative embodiment where multiple diffraction reduction portions DRP1, DRP2, DRP3 are not provided, multiple pixels PX can have the same shape through multiple transmission openings POP1, POP2, POP3. As a result, a diffraction pattern may be generated due to the multiple pixels PX.

[0186] In an embodiment, a color filter corresponding to each of the plurality of transmission apertures POP1, POP2, and POP3 can be disposed in the corresponding pixel among the first pixel PX1 to the third pixel PX3. For example, a first color filter can be disposed in each of the plurality of first transmission apertures POP1. The first color filter can cover any one of the plurality of first diffraction reduction portions DRP1.

[0187] Figure 10 This is a cross-sectional view of the display module DPM-1 according to an embodiment of the present disclosure.

[0188] Reference Figure 10The display module DPM-1 may also include a light-reflecting portion LRP (e.g., a light-reflecting unit). The light-reflecting portion LRP can be configured to reflect incident light.

[0189] The light-reflecting portion LRP can overlap with multiple light-emitting diodes (LDs) (e.g., on the third-direction DR3). The light-reflecting portion LRP can also overlap with multiple diffraction-reducing portions DRP. In an embodiment, the light-reflecting portion LRP can be disposed between the encapsulation layer TFE and the upper input sensor insulating layer UDL in the thickness direction of the display module (e.g., on the third-direction DR3). For example, the light-reflecting portion LRP can be disposed between the intermediate input sensor insulating layer MDL and the upper input sensor insulating layer UDL in the thickness direction of the display module (e.g., on the third-direction DR3).

[0190] Light emitted from multiple light-emitting diodes (LDs) can be reflected downwards from the light-reflecting portion LRP. Light reflected downwards from the light-reflecting portion LRP can also be reflected upwards from the cathode electrodes of the multiple LDs. The light-reflecting portion LRP can be configured to reflect light towards multiple diffraction reduction portions DRPs. Therefore, due to the light-reflecting portion LRP, the amount of light incident on and absorbed by the multiple diffraction reduction portions DRPs can be reduced. The light-reflecting portion LRP can improve the luminous efficiency of the display module DPM-1.

[0191] In this embodiment, the light-reflecting portion LRP may comprise the same material as the upper sensor electrode USP. In this embodiment, the light-reflecting portion LRP may be formed during the process of forming the upper sensor electrode USP. Therefore, the light-reflecting portion LRP can be easily formed without the need for a separate additional process.

[0192] Figure 11 This is a cross-sectional view of the display module DPM-2 according to an embodiment of the present disclosure.

[0193] Reference Figure 11 The recessed portion can be defined within the intermediate input sensor insulating layer MDL-1. The light-reflecting portion LRP-1 can be disposed within the recessed portion defined within the intermediate input sensor insulating layer MDL-1.

[0194] The light-reflecting portion LRP-1 can be disposed in a recessed portion defined in the insulating layer MDL-1 of the intermediate input sensor, and the light reflected by the light-reflecting portion LRP-1 can be diffusely reflected. Therefore, light can be reflected by the light-reflecting portion LRP-1 and the cathode electrodes of the multiple light-emitting diodes (LDs) to prevent the display module DPM-2 from appearing bright at a specific viewing angle.

[0195] Figure 12It is a plan view of any one of the plurality of pixels PX-1 according to embodiments of the present disclosure.

[0196] Reference Figure 12 In this embodiment, pixel PX-1 may include a first color sub-pixel SPX-R-1, a second color sub-pixel SPX-G-1, and a third color sub-pixel SPX-B-1. Pixel PX-1 may be a pixel PX-1 with a striped pattern.

The third color sub-pixel SPX-B-1 may be defined as being spaced apart from the second color sub-pixel SPX-G-1 in the first direction DR1.

[0198] The first color sub-pixel SPX-R-1 can be defined by the first color transmission aperture POP-R-1. The second color sub-pixel SPX-G-1 can be defined by the second color transmission aperture POP-G-1.

[0199] In the planar view, each of the multiple transmission apertures POP-1 can have a rectangular shape. Each of the multiple diffraction reduction portions DRP can have a circular shape. Even when each of the multiple transmission apertures POP-1 has a rectangular shape, a corresponding diffraction reduction portion DRP can be placed in each of the multiple transmission apertures POP-1 to reduce diffraction phenomena caused by the multiple transmission apertures POP-1.

[0201] Reference Figure 13 Each of the multiple diffraction reduction portions DRP-1 (first color diffraction reduction portion DRP-R-1, second color diffraction reduction portion DRP-G-1, and third color diffraction reduction portion DRP-B-1) can each have a rectangular shape with a long side extending in the second direction DR2 in a planar view. Similarly, each of the multiple transmission openings POP-1 can have a rectangular shape with a long side extending in the second direction DR2 in a planar view.

[0202] Even when the multiple diffraction reduction portions DRP-1 each have a non-circular shape, the corresponding diffraction reduction portion DRP-1 among the multiple diffraction reduction portions DRP-1 can be set in each of the multiple transmission openings POP-1 to reduce diffraction phenomena caused by the multiple transmission openings POP-1.

[0205] exist Figure 14 In this embodiment, the direction pointed to by the fourth direction axis DR4 can be defined as the fourth direction DR4. Furthermore, the direction pointed to by the fifth direction axis DR5 can be defined as the fifth direction DR5. The fourth direction DR4 and the fifth direction DR5 are the diagonal directions between the first direction DR1 and the second direction DR2. In some embodiments, the fourth direction DR4 and the fifth direction DR5 may intersect each other. However, the embodiments of this disclosure are not necessarily limited to this.

[0206] In a planar view, the first color subpixel SPX-R-2 may have a quadrilateral shape extending in the fourth direction DR4 and the fifth direction DR5. The two second color subpixels SPX-G-2 may (e.g., in a planar view) have polygonal shapes. One of the second color subpixels SPX-G-2 may be defined as being spaced apart from the first color subpixel SPX-R-2 in the fourth direction DR4. The other of the second color subpixels SPX-G-2 may be defined as being spaced apart from the first color subpixel SPX-R-2 in the fifth direction DR5. The third color subpixel SPX-B-2 may have a quadrilateral shape extending in the fourth direction DR4 and the fifth direction DR5. The third color subpixel SPX-B-2 may be defined as being spaced apart from the first color subpixel SPX-R-2 in the second direction DR2.

[0207] The first color sub-pixel SPX-R-2 can be defined by a first color transmission aperture POP-R-2. Each of the plurality of second color sub-pixels SPX-G-2 can be defined by a corresponding second color transmission aperture POP-G-2 among the plurality of second color transmission apertures POP-G-2. The third color sub-pixel SPX-B-2 can be defined by a third color transmission aperture POP-B-2.

[0208] In the plan view, the plurality of transmission apertures POP-2 may each have a quadrilateral or other polygonal shape. Even when the plurality of transmission apertures POP-2 each have a quadrilateral or other polygonal shape, a corresponding diffraction reduction portion DRP among the plurality of diffraction reduction portions DRP can be provided in each of the plurality of transmission apertures POP-2 to reduce diffraction phenomena caused by the plurality of transmission apertures POP-2. In an embodiment, each of the plurality of diffraction reduction portions DRP may (e.g., in the plan view) have a circular shape.

[0210] Reference Figure 15A and Figure 15B The display module DPM-3 may have multiple pixel groups PXG1 and PXG2 defined within the display module DPM-3. In an embodiment, the multiple pixel groups PXG1 and PXG2 may include a first pixel group PXG1 and a second pixel group PXG2. However, embodiments of this disclosure are not limited to this, and the number of multiple pixel groups may vary. The display module DPM-3 may have multiple pixels PX defined within the display module DPM-3. In an embodiment, the multiple pixels PX may include a first pixel PX1, a second pixel PX2, a third pixel PX3, a fourth pixel PX4, a fifth pixel PX5, a sixth pixel PX6, a seventh pixel PX7, and an eighth pixel PX8.

[0211] Multiple pixel groups PXG1 and PXG2 may each include multiple pixels PX. In an embodiment, multiple pixel groups PXG1 and PXG2 may each include multiple pixels PX disposed in a region extending a first repetition distance RPD1 in a first direction DR1 and extending a second repetition distance RPD2 in a second direction DR2.

[0212] In this embodiment, the first repetition distance RPD1 can be an integer multiple of the first pixel distance DPD1. For example, the first repetition distance RPD1 can be two, three, or four times the first pixel distance DPD1. The second repetition distance RPD2 can be an integer multiple of the second pixel distance DPD2. The second repetition distance RPD2 can be two, three, or four times the second pixel distance DPD2.

[0214] In an embodiment, the first pixel group PXG1 may include a first pixel PX1, a second pixel PX2, a fifth pixel PX5, and a sixth pixel PX6. The multiple pixels PX1, PX2, PX5, and PX6 included in the first pixel group PXG1 may have the same shape as each other.

[0215] Multiple diffraction reduction portions DRP1 and DRP2 set in each of multiple pixels PX1, PX2, PX5, and PX6 can have the same shape as each other. Therefore, multiple diffraction reduction portions DRP1 and DRP2 can be easily set. For example, multiple diffraction reduction portions DRP1 and DRP2 set in multiple pixels PX1, PX2, PX5, and PX6 can be set together.

In an embodiment, the first arrangement direction can be a first direction DR1. The first arrangement distance can be a first pixel distance DPD1.

[0221] In the plan view, the centroid of each of the plurality of second diffraction reduction portions DRP2 can be spaced apart from the centroid of the corresponding first diffraction reduction portion DRP1 in the plurality of first diffraction reduction portions DRP1 by a first arrangement distance in the first arrangement direction.

[0222] For example, the shape of the plurality of second transmission openings POP2 defined in the second pixel PX2 can be the same as the shape of the plurality of first transmission openings POP1 defined in the first pixel PX1. Furthermore, the shape of the plurality of second diffraction reduction portions provided in the second pixel PX2 can be the same as the shape of the plurality of first diffraction reduction portions DRP1 provided in the first pixel PX1.

[0223] The third pixel PX3 may have multiple third transmission openings POP3 defined within the third pixel PX3. Multiple third diffraction reduction portions DRP3 may be provided within the third pixel PX3.

[0225] In the plan view, the centroid of each of the plurality of third diffraction reduction portions DRP3 can be spaced apart from the centroid of the corresponding second diffraction reduction portion DRP2 in a direction different from the first arrangement direction by a distance different from the first arrangement distance.

[0226] For example, the shape of the plurality of third transmission openings POP3 defined in the third pixel PX3 can be the same as the shape of the plurality of second transmission openings POP2 defined in the second pixel PX2. Furthermore, the shape of the plurality of third diffraction reduction portions DRP3 provided in the third pixel PX3 can be different from the shape of the plurality of second diffraction reduction portions DRP2 provided in the second pixel PX2.
