[0038] In this specification, it will be understood that when an element (or region, layer, or portion, etc.) is referred to as being "on" another element, "connected to" or "coupled to" another element, it may be disposed directly on, directly connected to or coupled to the other element, or other elements may be disposed between the element and the other element.

[0039] In this specification, it will be understood that "direct placement" means that there is no intervening layer, membrane, region, or plate between one part of a layer, membrane, region, or plate and another part. For example, "direct placement" can mean placement between two layers or two components without the use of additional components such as adhesive members.

[0040] The same reference numerals or symbols refer to the same elements throughout. In the drawings, the thickness, proportions, and dimensions of elements are exaggerated for the purpose of effectively describing the technical content. The term "and / or" includes all of one or more combinations defined by the associated elements.

[0041] Although terms such as "first," "second," etc., may be used to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. For example, a first element may be referred to as a second element without departing from the scope of the inventive concept. Similarly, a second element may be referred to as a first element. In this specification, unless the context clearly indicates otherwise, the singular expressions "a" and "the (described)" are intended to include the plural forms as well.

[0042] Additionally, terms such as "below," "underneath," "on the lower side," "above," "above," or "on the upper side" may be used to describe the relationships between the elements illustrated in the accompanying drawings. These terms are relative concepts and are described based on the directions indicated in the drawings.

[0043] It will be further understood that the terms “comprising,” “including,” “having,” and / or variations thereof, when used in this specification, indicate the presence of stated features, values, steps, operations, elements, components, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, values, steps, operations, elements, components, and / or combinations thereof.

[0044] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will be further understood that terms such as those defined in common dictionaries shall be interpreted as having the meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0045] In the following description, embodiments of the inventive concept will be described with reference to the accompanying drawings.

[0046] Figures 1A to 1C This is a perspective view of an electronic device ED according to an embodiment of the present invention. Figure 1A The diagram shows the unfolded state of the electronic device ED, and Figure 1B and Figure 1C The diagrams show two different folded states of the electronic device ED.

[0047] refer to Figures 1A to 1C An electronic device ED according to an embodiment of the present invention may include a display surface DS defined by a first direction DR1 and a second direction DR2 intersecting the first direction DR1. The electronic device ED can provide an image IM to a user through the display surface DS.

[0048] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. The display area DA may display an image IM, and the non-display area NDA may not display an image IM. The non-display area NDA may surround the display area DA.

[0049] The display surface DS may include a sensing area TA. The sensing area TA may be a portion of the display area DA. The sensing area TA has a higher transmittance than other areas of the display area DA. In the following text, the area of ​​the display area DA other than the sensing area TA may be defined as the general display area.

[0050] For example, optical signals such as visible or infrared light can be transmitted to the sensing area TA. The electronic device ED can use visible light passing through the sensing area TA to capture external images, or use infrared light to determine whether an external object is approaching. Figure 1A The illustration shows a sensing area TA, but embodiments of the present invention are not limited thereto. Multiple sensing areas TA may be provided.

[0051] In the following description, the direction substantially perpendicular to the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. The third direction DR3 is a reference direction that distinguishes the front and rear surfaces of each component. In this specification, the term "in a plane" can be defined as the state when viewed in the third direction DR3. In the following description, the first to third directions DR1, DR2, and DR3 are directions indicated by the corresponding first to third direction axes and are denoted using the same reference numerals or symbols.

[0052] The electronic device ED may include a folded region FA and multiple non-folded regions NFA1 and NFA2. The non-folded regions NFA1 and NFA2 may include a first non-folded region NFA1 and a second non-folded region NFA2. In the second direction DR2, the folded region FA may be disposed between the first non-folded region NFA1 and the second non-folded region NFA2.

[0053] like Figure 1B As shown, the folding region FA of the electronic device ED can be folded about a folding axis FX parallel to the first direction DR1. The folding region FA has a predetermined curvature and radius of curvature R1. The electronic device ED can be folded inward (inward folding) such that the first non-folding region NFA1 and the second non-folding region NFA2 face each other and the display surface DS is not exposed.

[0054] like Figure 1CAs shown, the electronic device ED can be folded outward (outward folding) to expose the display surface DS. In embodiments of the present invention, the electronic device ED can be configured to repeatedly perform inward or outward folding operations from an unfolded state, and vice versa, but embodiments of the present invention are not limited thereto. In embodiments of the present invention, the electronic device ED can be configured to perform any one of unfolding, inward folding, and outward folding operations.

[0055] A foldable electronic device ED is illustrated in an embodiment of the present invention, but the embodiments of the present invention are not limited thereto. The electronic device ED may be a tablet electronic device or a rollable electronic device. In an embodiment of the present invention, the electronic device ED is exemplarily illustrated as a mobile phone, but is not limited thereto. In an embodiment of the present invention, the electronic device ED may be applied to large electronic devices such as televisions and monitors, as well as small and medium-sized electronic devices such as tablet computers, car navigation systems, game consoles, and smartwatches.

[0056] Figure 2A This is an exploded perspective view of an electronic device ED according to an embodiment of the present invention. Figure 2B This is a block diagram of an electronic device ED according to an embodiment of the present invention.

[0057] like Figure 2A As shown, the electronic device ED may include a display device DD, an electronic module EM, an electro-optical module ELM, a power supply module PSM, and a housing HM. Although not shown separately, the electronic device ED may further include a mechanical structure for controlling the folding operation of the display device DD.

[0058] The display device DD generates images and detects external input. The display device DD includes a window WM and a display module DM. The window WM provides the front surface of the electronic device ED. The window WM will be described in detail later.

[0059] The display module (DM) may include at least the display panel (DP). Figure 2A The illustration only shows the display panel DP in the stacked structure of the display module DM, but in reality, the display module DM may further include multiple components disposed above the display panel DP. The stacked structure of the display module DM will be described in detail later.

[0060] A display panel DP can be a light-emitting display panel, but is not particularly limited to any of them. For example, a display panel DP can be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of an organic light-emitting display panel may include organic light-emitting materials. The light-emitting layer of a quantum dot light-emitting display panel may include quantum dots and / or quantum rods, etc. In the following, the display panel DP is described as an organic light-emitting display panel.

[0061] The display panel DP includes the display area DA, which is connected to the electronic device ED (see...). Figure 1A ) and non-display area NDA (see Figure 1A The corresponding display area DP-DA and non-display area DP-NDA. In this specification, the term "area / part corresponding to area / part" means "overlapping with each other", and the areas / parts are not limited to having the same area.

[0062] The display panel DP can include and Figure 1A The sensing area DP-TA corresponds to the sensing area TA. The sensing area DP-TA can be an area with a lower resolution than the display area DP-DA. The sensing area DP-TA will be described in detail later.

[0063] like Figure 2A As shown, the driver chip DIC can be located on the non-display area DP-NDA of the display panel DP. The flexible circuit board FCB can be coupled to the non-display area DP-NDA of the display panel DP. The flexible circuit board FCB can be connected to the main circuit board. The main circuit board can be an electronic component constituting the electronic module EM.

[0064] The driver chip DIC may include, for example, driving elements for driving pixels of the display panel DP, such as data driving circuitry. Figure 2A The illustration shows a structure in which the driver chip DIC is mounted on the display panel DP, but embodiments of the present invention are not limited thereto. For example, the driver chip DIC can also be mounted on a flexible circuit board FCB.

[0065] like Figure 2B As shown, the display device DD may further include an input sensor IS and a digitizer DTM. The input sensor IS detects user input. A capacitive input sensor IS may be disposed on the display panel DP. The digitizer DTM detects input from a stylus. An electromagnetic digitizer DTM may be disposed below the display panel DP.

[0066] The electronic module EM may include a control module 10, a wireless communication module 20, an image input module 30, a sound input module 40, a sound output module 50, a memory 60, an external interface module 70, etc. The electronic module EM may include a main circuit board, and these modules may be mounted on the main circuit board or electrically connected to the main circuit board via a flexible circuit board. The electronic module EM is electrically connected to the power supply module PSM.

[0067] refer to Figure 2A and Figure 2BAn electronic module EM can be disposed in each of the first housing HM1 and the second housing HM2, and a power supply module PSM can be disposed in each of the first housing HM1 and the second housing HM2. Although not shown, the electronic module EM disposed in the first housing HM1 can be electrically connected to the electronic module EM disposed in the second housing HM2 via a flexible circuit board.

[0068] The control module 10 controls the overall operation of the electronic device ED. For example, the control module 10 activates or disables the display device DD in response to user input. The control module 10 can also control the image input module 30, the sound input module 40, the sound output module 50, etc., in response to user input. The control module 10 may include at least one microprocessor.

[0069] The wireless communication module 20 can send / receive wireless signals to / from another terminal via Bluetooth or Wi-Fi. The wireless communication module 20 can also send / receive voice signals via typical communication lines. The wireless communication module 20 may include multiple antenna modules.

[0070] The image input module 30 processes image signals and converts them into image data that can be displayed on the display device DD. The sound input module 40 receives external sound signals using a microphone in recording mode, voice recognition mode, etc., and converts the received sound signals into electronic voice data. The sound output module 50 converts sound data received from the wireless communication module 20 or sound data stored in the memory 60, and outputs the converted sound data to the outside.

[0071] The external interface module 70 serves as an interface for connecting to an external charger, wired / wireless data port, card (e.g., memory card, SIM / UIM card) socket, etc.

[0072] The Power Supply Module (PSM) supplies the power required for the overall operation of the electronic device (ED). A typical PSM may include a battery device.

Although not shown, the electronic device ED may further include a hinge structure for connecting the first housing HM1 and the second housing HM2.

[0075] Figure 3 This is a plan view of a display panel DP according to an embodiment of the present invention.

[0076] refer to Figure 3 The display panel (DP) may include a display area (DP-DA) and a non-display area (DP-NDA) surrounding the display area (DP-DA). The display area (DP-DA) and the non-display area (DP-NDA) are distinguished by pixels (PX). Pixels (PX) are located within the display area (DP-DA). Scan driver (SDV), data driver, and transmit driver (EDV) may be located within the non-display area (DP-NDA). The data driver may be part of the circuitry formed within the driver chip (DIC).

[0077] The display panel DP comprises a first zone AA1, a second zone AA2, and a bend zone BA, divided along the second direction DR2. The second zone AA2 and the bend zone BA may be portions of the non-display area DP-NDA. The bend zone BA is located between the first zone AA1 and the second zone AA2.

[0078] Zone 1 AA1 is with Figure 1A The area corresponding to the display surface DS. The first area AA1 may include a first non-folded area NFA10, a second non-folded area NFA20, and a folded area FA0. The first non-folded area NFA10, the second non-folded area NFA20, and the folded area FA0 are respectively... Figures 1A to 1C The first non-folded region NFA1, the second non-folded region NFA2, and the folded region FA correspond to each other.

[0079] In the first direction DR1, the lengths of the bending zone BA and the second zone AA2 can be less than the length of the first zone AA1. Regions with shorter lengths in the bending axis direction can be bent more easily.

[0080] The display panel (DP) may include multiple pixels (PX), multiple scan lines SL1 to SLm, multiple data lines DL1 to DLn, multiple emission lines EL1 to ELm, a first control line CSL1, a second control line CSL2, a power line PL, and multiple pads (PD). Here, m and n are natural numbers greater than 0. Pixels (PX) may be connected to scan lines SL1 to SLm, data lines DL1 to DLn, and emission lines EL1 to ELm.

[0081] Scan lines SL1 to SLm can extend in the first direction DR1 to connect to the scan driver SDV. Data lines DL1 to DLn can extend in the second direction DR2 to connect to the driver chip DIC via the bend area BA. Transmit lines EL1 to ELm can extend in the first direction DR1 to connect to the transmit driver EDV.

[0082] The power line PL may include a portion extending in the second direction DR2 and a portion extending in the first direction DR1. The portions extending in the first direction DR1 and the portions extending in the second direction DR2 may be disposed on different layers. A portion of the power line PL extending in the second direction DR2 may extend to the second region AA2 via the bending region BA. The power line PL can supply a first voltage to the pixel PX.

[0083] The first control line CSL1 can be connected to the scan driver SDV and can extend through the bend area BA toward the lower end of the second area AA2. The second control line CSL2 can be connected to the transmit driver EDV and can extend through the bend area BA toward the lower end of the second area AA2.

[0084] On the plane, the pad PD can be positioned adjacent to the lower end of the second area AA2. The driver chip DIC, power line PL, first control line CSL1, and second control line CSL2 can be connected to the pad PD. The flexible circuit board FCB can be electrically connected to the pad PD via an anisotropic conductive adhesive layer.

[0085] The sensing area DP-TA can be a region with higher transmittance and lower resolution than the display area DP-DA. Transmittance and resolution are measured within a reference area. Within the reference area, the sensing area DP-TA has a smaller occupancy of light-shielding structures than the display area DP-DA. The light-shielding structures may include conductive patterns of circuit layers, electrodes of light-emitting elements, light-shielding patterns, etc., as described later.

[0086] Within the reference area (or the same area), the sensing area DP-TA has fewer pixels than the display area DP-DA. Essentially, the sensing area DP-TA can be the area through which the light signal passes.

[0087] Figure 4 This is an enlarged plan view of a portion of the display area DP-DA of a display panel DP according to an embodiment of the present invention.

[0088] refer to Figure 4 Multiple luminescent areas LA-R, LA-G, and LA-B are positioned within the display area DP-DA. A non-luminescent area NLA is positioned adjacent to the multiple luminescent areas LA-R, LA-G, and LA-B. The non-luminescent area NLA defines the boundaries of the multiple luminescent areas LA-R, LA-G, and LA-B and prevents color mixing between them. The multiple luminescent areas LA-R, LA-G, and LA-B can be defined as multiple luminescent rows LAL-1 and LAL-2 extending in the first direction DR1. Figure 4In this context, the first direction DR1 is defined as the extension direction (or row direction) of the light-emitting rows LAL-1 and LAL-2, and the second direction DR2 is defined as the column direction.

[0089] In embodiments of the present invention, multiple light-emitting rows LAL-1 and LAL-2 can be divided into two groups. The first group of light-emitting rows LAL-1 includes a first-color light-emitting region LA-R that generates a first-color light and a third-color light-emitting region LA-B that generates a third-color light. The first-color light-emitting region LA-R and the third-color light-emitting region LA-B are alternately arranged along the row direction DR1. The first group of light-emitting rows LAL-1 can also include a first light-emitting row LAL-11 and a second light-emitting row LAL-12. The first light-emitting row LAL-11 and the second light-emitting row LAL-12 can be alternately arranged along the column direction DR2.

[0090] Both the first emitting row LAL-11 and the second emitting row LAL-12 have a first color emitting area LA-R and a third color emitting area LA-B, but they are offset from each other by one area in the first direction DR1. Using this offset, the first color emitting area LA-R and the third color emitting area LA-B alternate in the column direction DR2. For example, the first color emitting area LA-R of the first emitting row LAL-11 and the third color emitting area LA-B of the second emitting row LAL-12 are aligned in the second direction DR2, and the third color emitting area LA-B of the first emitting row LAL-11 and the first color emitting area LA-R of the second emitting row LAL-12 can also be aligned in the second direction DR2.

[0091] The second group of emitting rows LAL-2 may include the second color emitting region LA-G that generates the second color light. The second group of emitting rows LAL-2 may include the third emitting row LAL-21 and the fourth emitting row LAL-22.

[0092] The third and fourth light-emitting rows LAL-21 and LAL-22 may include a second color light-emitting area LA-G extending along the first direction DR1. The third and fourth light-emitting rows LAL-21 and LAL-22 may be alternately arranged along the column direction DR2.

[0093] In embodiments of the present invention, the first color emitting region LA-R, the second color emitting region LA-G, and the third color emitting region LA-B are illustrated exemplarily as having different planar areas; however, embodiments of the present invention are not limited thereto. The illustration shows that among the aforementioned emitting regions, the third color emitting region LA-B has the largest area and the second color emitting region LA-G has the smallest area, but this is merely an illustrative example.

[0094] In an embodiment of the present invention, the first color emitting region LA-R can generate red light, the second color emitting region LA-G can generate green light, and the third color emitting region LA-B can generate blue light. However, the embodiments of the present invention are not limited thereto, and the colored light emitted by the first color emitting region LA-R, the second color emitting region LA-G, and the third color emitting region LA-B can be selected from a combination of three colors of light that can generate white light when mixed.

[0095] In an embodiment of the present invention, multiple light-emitting areas LA-R, LA-G, and LA-B with circular shapes are illustrated, but the shapes are not limited to this and may also have polygonal shapes.

[0096] Figure 5 This is a cross-sectional view of a display module DM according to an embodiment of the present invention. Figure 5 The diagram illustrates along Figure 2A The cross section of the display module DM is taken by line I-I'.

[0097] refer to Figure 5 The display module DM may include a display panel DP, an input sensor IS, and an anti-reflective layer ARL. The display panel DP may include a substrate layer BL, a circuit layer DP-CL, a light-emitting element layer DP-EL, and a packaging layer TFE.

[0098] The substrate layer BL can provide a substrate surface on which the circuit layer DP-CL is disposed. The substrate layer BL can be a flexible substrate that is bendable, foldable, rollable, etc. The substrate layer BL can be a glass substrate, a metal substrate, or a polymer substrate, etc. However, embodiments of the present invention are not limited thereto, and the substrate layer BL can be an inorganic layer, an organic layer, or a composite material layer.

[0099] The substrate layer BL can have a multilayer structure. For example, the substrate layer BL may include a first synthetic resin layer, multiple or single inorganic layers, and a second synthetic resin layer disposed on the multiple or single inorganic layers. The first and second synthetic resin layers may each comprise a polyimide resin, and are not particularly limited thereto.

[0100] The circuit layer DP-CL can be disposed on the substrate layer BL. The circuit layer DP-CL may include insulating layers, semiconductor patterns, conductive patterns, signal lines, etc.

The encapsulation layer TFE may include at least one inorganic layer. The encapsulation layer TFE may include a stacked structure of inorganic layer / organic layer / inorganic layer.

[0103] The input sensor IS can be directly mounted on the display panel DP. The input sensor IS can be formed on the display panel DP through a continuous process. Here, the term "directly mounted" can mean that another component is not located between the input sensor IS and the display panel DP. That is, a separate adhesive component may not be located between the input sensor IS and the display panel DP. The display panel DP generates an image, and the input sensor IS acquires coordinate information about external inputs (e.g., touch events).

[0104] An anti-reflective layer (ARL) can be directly disposed on the input sensor (IS). The ARL reduces the reflectivity of external light (e.g., natural light or sunlight) incident on the display device (DD). The ARL may include color filters. The color filters may have a predetermined arrangement. For example, the color filters may be arranged considering the color of light emitted from pixels included in the display panel (DP). Furthermore, the ARL may further include a light-shielding pattern adjacent to the color filters.

[0105] In an embodiment of the present invention, the positions of the input sensor IS and the anti-reflective layer ARL can be interchanged.

Figure 6 The diagram illustrates the following: Figure 5 A portion of the display module DM in the embodiment illustrated in the figure. (See reference) Figure 6 , omission and reference Figure 5 The description of the construction is the same as the description of the construction, and references Figure 5 The description.

[0107] Figure 6 The diagram shows a cross section corresponding to a light-emitting region LA and a non-light-emitting region NLA surrounding the light-emitting region LA. Figure 6 Only one light-emitting area LA is illustrated as an example, but multiple light-emitting areas LA can be provided. Figure 6 The illustration shows a light-emitting element (LD) and a transistor TFT connected to the LD. The transistor TFT can be one of a plurality of transistors included in the driving circuitry of a pixel. In embodiments of the present invention, the transistor TFT is described as a silicon transistor, but it can also be a metal-oxide-semiconductor transistor.

[0109] A buffer layer (BFL) can be disposed on the substrate layer (BL). The buffer layer (BFL) prevents metal atoms or impurities from diffusing from the substrate layer (BL) into the semiconductor pattern disposed on the buffer layer (BFL). The semiconductor pattern includes the active region (AC1). The buffer layer (BFL) can ensure uniform formation of the semiconductor pattern by controlling the heating rate during the crystallization process.

[0110] Although not illustrated, a back metal layer can be disposed between the substrate layer BL and the buffer layer BFL. The back metal layer can be disposed below the transistor TFT and blocks external light from reaching the transistor TFT.

For example, the silicon semiconductor can include amorphous silicon, polycrystalline silicon, etc. For example, the semiconductor patterns can include low-temperature polycrystalline silicon.

[0112] The semiconductor pattern may include a first region with high conductivity and a second region with low conductivity. The first region may be doped with either N-type or P-type dopant. A P-type transistor may include a doped region doped with P-type dopant, and an N-type transistor may include a doped region doped with N-type dopant. The second region may be an undoped region or a region doped at a lower concentration than the first region.

[0113] The conductivity of the first region is greater than that of the second region, and the first region can substantially function as an electrode or signal line. The second region can substantially correspond to the active region (or channel) of a transistor. That is, a portion of the semiconductor pattern can be the active region of a transistor, another portion can be the source or drain of a transistor, and yet another portion can be a connecting electrode or a connecting signal line.

[0114] A transistor TFT may include a source region SE1 (or source electrode), an active region AC1 (or channel), a drain region DE1 (or drain electrode), and a gate region GT1 (or gate). The source region SE1, active region AC1, and drain region DE1 of the transistor TFT may be formed by a semiconductor pattern. In cross-section, the source region SE1 and the drain region DE1 may extend from the active region AC1 in opposite directions to each other. Figure 6 The illustration shows a portion of the signal transmission region SCL formed by a semiconductor pattern.

In embodiments of the present invention, the first insulating layer IL1 may be a single silicon oxide layer. The insulating layers in the circuit layer DP-CL, described later, other than the first insulating layer IL1, may be inorganic layers and / or organic layers, and may have a single-layer or multi-layer structure. The inorganic layer may include at least one of the materials described above, but is not limited thereto.

[0117] The gate GT1 of the transistor TFT can be disposed on the first insulating layer IL1. The gate GT1 can be part of a metal pattern. The gate GT1 can overlap with the active region AC1. During the process of doping the semiconductor pattern, the gate GT1 can act as a mask. The gate GT1 can include titanium (Ti), silver (Ag), silver-containing alloys, molybdenum (Mo), molybdenum-containing alloys, aluminum (Al), aluminum-containing alloys, aluminum nitride (AlN), tungsten (W), tungsten nitride (WN), copper (Cu), indium tin oxide (ITO), indium zinc oxide (IZO), etc., but the embodiments of the present invention are not particularly limited thereto.

[0118] The second insulating layer IL2 can be disposed on the first insulating layer IL1 and cover the gate GT1. The third insulating layer IL3 can be disposed on the second insulating layer IL2.

[0119] The first connecting electrode CNE1 can be disposed on the third insulating layer IL3. The first connecting electrode CNE1 can be connected to the signal transmission area SCL via a contact hole CNT-1 passing through the first to third insulating layers IL1, IL2 and IL3. The fourth insulating layer IL4 can be disposed on the third insulating layer IL3 and cover the first connecting electrode CNE1. The fourth insulating layer IL4 can be an organic layer.

[0120] The fifth insulating layer IL5 can be disposed on the fourth insulating layer IL4. The second connecting electrode CNE2 can be disposed on the fifth insulating layer IL5. The second connecting electrode CNE2 can be connected to the first connecting electrode CNE1 via a contact hole CNT-2 passing through the fourth insulating layer IL4 and the fifth insulating layer IL5. The fifth insulating layer IL5 can be an organic layer.

[0121] The sixth insulating layer IL6 can be disposed on the fifth insulating layer IL5 and cover the second connection electrode CNE2. The sixth insulating layer IL6 can be an organic layer. The stacked structure of the first to sixth insulating layers IL1, IL2, IL3, IL4, IL5 and IL6 is presented merely as an example, and in addition to the first to sixth insulating layers IL1, IL2, IL3, IL4, IL5 and IL6, additional conductive and insulating layers can be further disposed.

[0122] The light-emitting element layer DP-EL can be disposed on the circuit layer DP-CL. The light-emitting element layer DP-EL may include light-emitting elements LD and pixel-defining layers PDL.

[0123] The light-emitting element (LD) may include a first electrode AE ​​(or anode), a light-emitting layer EL, and a second electrode CE (or cathode). The second electrode CE may be commonly disposed in multiple pixels (PX).

[0124] The first electrode AE ​​of the light-emitting element LD can be disposed on the sixth insulating layer IL6. The first electrode AE ​​of the light-emitting element LD can be connected to the second connecting electrode CNE2 via a contact hole CNT-3 passing through the sixth insulating layer IL6. The first electrode AE ​​of the light-emitting element LD can be a semi-transparent reflective electrode or a reflective electrode. According to embodiments of the present invention, the first electrode AE ​​of the light-emitting element LD can each include a reflective layer formed of Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr or compounds thereof, and a transparent or semi-transparent electrode layer formed on the reflective layer. The transparent or semi-transparent electrode layer can include at least one selected from the group consisting of indium tin oxide (ITO), indium zinc oxide (IZO), indium gallium zinc oxide (IGZO), zinc oxide (ZnO), indium oxide (In2O3), and aluminum-doped zinc oxide (AZO). For example, the first electrode AE ​​of the light-emitting element LD can include a stacked structure of ITO / Ag / ITO.

[0125] A pixel-defining layer (PDL) may be disposed on a sixth insulating layer (IL6). The PDL may absorb light and, for example, may be black. The PDL may include a black colorant. The black colorant may include black dyes and black pigments. The black colorant may include carbon black, metals such as chromium, or oxides thereof. The PDL may correspond to a light-shielding pattern with light-shielding properties.

[0126] The pixel defining layer (PDL) can cover a portion of the first electrode AE ​​of the light-emitting element (LD). For example, a light-emitting opening (PDL-OP) exposing a portion of the first electrode AE ​​of the LD can be defined within the pixel defining layer (PDL). The light-emitting opening (PDL-OP) of the pixel defining layer (PDL) can define the light-emitting area LA. The pixel defining layer (PDL) can increase the distance between the edge of the first electrode AE ​​and the second electrode CE. Therefore, the pixel defining layer (PDL) can be used to prevent electric arcs or the like from occurring at the edge of the first electrode AE.

[0127] Although not illustrated, a hole control layer may be disposed between the first electrode AE ​​and the light-emitting layer EL. The hole control layer may include a hole transport layer and may further include a hole injection layer. An electron control layer may be disposed between the light-emitting layer EL and the second electrode CE. The electron control layer may include an electron transport layer and may further include an electron injection layer.

[0128] The encapsulation layer TFE can be disposed on the light-emitting element layer DP-EL. The encapsulation layer TFE may include an inorganic layer TFE1, an organic layer TFE2, and an inorganic layer TFE3 stacked in sequence, but the layers constituting the encapsulation layer TFE are not limited to these.

[0129] Inorganic layers TFE1 and TFE3 protect the DP-EL light-emitting element layer from moisture and oxygen, while organic layer TFE2 protects the DP-EL layer from foreign matter such as dust particles. Inorganic layers TFE1 and TFE3 may include silicon nitride, silicon oxynitride, silicon oxide, titanium oxide, or aluminum oxide layers, etc. Organic layer TFE2 may include, but is not limited to, acrylic organic layers.

[0130] The input sensor IS can be mounted on the display panel DP. The input sensor IS can be referred to as a sensor, an input sensing layer, or an input sensing panel. The input sensor IS may include a sensor insulating layer 210, a first sensor conductive layer 220, an intermediate sensor insulating layer 230, a second sensor conductive layer 240, a sensor organic layer 250, and a sensor inorganic layer 260. The sensor insulating layer 210 and the intermediate sensor insulating layer 230 may be omitted, as may one of the first sensor conductive layer 220 and the second sensor conductive layer 240.

[0131] The sensor insulating layer 210 can be directly disposed on the display panel DP. The sensor insulating layer 210 can be an inorganic layer comprising at least one of silicon nitride, silicon oxynitride, and silicon oxide. Alternatively, the sensor insulating layer 210 can also be an organic layer comprising epoxy resin, acrylic resin, or imide resin. The sensor insulating layer 210 can have a single-layer structure or a multilayer structure in which the layers are stacked along a third direction DR3.

[0132] The first sensor conductive layer 220 and the second sensor conductive layer 240 may each have a single-layer structure or a multilayer structure in which each layer is stacked on a third-direction DR3. The first sensor conductive layer 220 and the second sensor conductive layer 240 may include conductive patterns defining electrodes with a grid shape. The conductive patterns may not overlap with the light-emitting aperture PDL-OP, but may overlap with the pixel defining layer PDL. In this specification, the first sensor conductive layer 220 and the second sensor conductive layer 240 may both be referred to as sensor conductive layers without distinction between them.

[0133] The conductive layer having a single-layer structure may include a metal layer or a transparent conductive layer. The metal layer may include molybdenum, silver, titanium, copper, aluminum, or alloys thereof. The transparent conductive layer may include transparent conductive oxides such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), and indium zinc tin oxide (IZTO). Alternatively, the transparent conductive layer may include conductive polymers such as PEDOT, metal nanowires, and graphene.

[0134] A conductive layer with a multilayer structure may include sequentially stacked metal layers. The metal layers may also have a three-layer structure, such as titanium / aluminum / titanium. A conductive layer with a multilayer structure may include at least one metal layer and at least one transparent conductive layer.

[0135] An intermediate sensor insulating layer 230 may be disposed between the first sensor conductive layer 220 and the second sensor conductive layer 240. The intermediate sensor insulating layer 230 may include an inorganic film. The inorganic film may include at least one of alumina, titanium dioxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, and hafnium oxide. Alternatively, the intermediate sensor insulating layer 230 may include an organic film. The organic film may include at least one of acrylic resins, methacrylic resins, polyisoprene, ethylene resins, epoxy resins, urethane resins, cellulose resins, siloxane resins, polyimide resins, polyamide resins, and perylene resins.

[0136] The sensor organic layer 250 is disposed on the second sensor conductive layer 240. Since the sensor organic layer 250 comprises an organic material and is provided to have a predetermined thickness or greater, the upper part of the conductive pattern of the conductive layer disposed below the sensor organic layer 250 can be planarized.

[0137] The sensor inorganic layer 260 can be disposed on the sensor organic layer 250. Alternatively, the sensor inorganic layer 260 can be directly disposed on the sensor organic layer 250. The sensor inorganic layer 260 may include inorganic materials to protect the conductive pattern disposed beneath it from external impacts and to block moisture and oxygen.

[0138] According to embodiments of the present invention, the inorganic layer 260 of the sensor can be referred to as an impact buffer layer, and the impact buffer layer 260 can have an elastic modulus greater than that of the organic layer 250 of the sensor. The impact buffer layer 260 can comprise a material having a modulus of approximately 10 GPa to approximately 150 GPa. For example, the impact buffer layer 260 can comprise a transparent conductive oxide (TCO) and a metal. Accordingly, the impact buffer layer 260 can prevent the organic layer 250 of the sensor from being damaged by external impacts, and thus can improve impact resistance.

[0139] An opening 260-OP overlapping the light-emitting region LA is defined within the sensor inorganic layer 260. A cavity 250-CVT extending from the opening 260-OP of the sensor inorganic layer 260 can be defined within the sensor organic layer 250. The sensor inorganic layer 260 and the sensor organic layer 250 can be patterned.

[0140] In this embodiment, inorganic material may be deposited on the sensor organic layer 250 to form a preliminary sensor inorganic layer. A photoresist mask is formed on the preliminary sensor inorganic layer, and the openings 260-OP and cavities 250-CVT extending from the openings 260-OP of the sensor inorganic layer 260 may then be patterned by a dry etching process. Figure 6 The illustration shows the edge of the opening 260-OP of the inorganic layer 260 of the sensor aligned with the edge of the cavity 250-CVT of the organic layer 250 of the sensor. However, in some embodiments, the edges of the opening 260-OP and the cavity 250-CVT may not be aligned, or may not be... Figure 6 In the embodiments, continuous, flat sidewalls are formed as described above.

[0141] Subsequently, the preliminary color filter, which will be described later, fills the opening 260-OP and the cavity 250-CVT, and can then be cured to form a plurality of color filters 320.

[0142] An anti-reflective layer ARL can be disposed on the input sensor IS. The anti-reflective layer ARL may include a light-shielding pattern 310, multiple color filters 320, and a planarization layer 330. However, the light-shielding pattern 310 may be omitted, and the light-shielding pattern 310 may serve as an alternative to multiple color filters 320 that can overlap.

[0143] The material constituting the light-shielding pattern 310 is not particularly limited as long as it absorbs light. The light-shielding pattern 310 has a black layer, and in embodiments, the light-shielding pattern 310 may include a black colorant. The black colorant may include black dyes and black pigments. The black colorant may include carbon black, metals such as chromium, or oxides thereof.

[0144] The light-shielding pattern 310 prevents external light from being reflected by the conductive pattern of the second sensor conductive layer 240 located below the light-shielding pattern 310. In the display module DM, the light-shielding pattern 310 may also be omitted. When the light-shielding pattern 310 is omitted, the area without the light-shielding pattern 310 can have higher light transmittance than other areas.

[0145] An opening 310-OP can be defined within a light-shielding pattern 310. On a plane, the opening 310-OP can overlap with the first electrode AE ​​of the light-emitting element LD. One of the plurality of color filters 320 can overlap with the first electrode AE ​​of the light-emitting element LD. One of the plurality of color filters 320 can cover the opening 310-OP. Each of the plurality of color filters 320 can contact the light-shielding pattern 310.

[0146] The planarization layer 330 may cover the light-shielding pattern 310 and multiple color filters 320. The planarization layer 330 may include an organic material and has a flat surface on its upper surface. The planarization layer 330 may include the same material as the sensor organic layer 250.

[0147] In this embodiment, the display module DM may not include a polarizer. Typically, when external light is incident on a polarizer disposed on the planarization layer 330, light reflected from the upper surface of the first electrode AE ​​or the side surface of the light-emitting opening PDL-OP of the pixel defining layer PDL is confined to propagate in a predetermined direction. Therefore, degradation of visibility and display quality can be prevented. However, the light emitted from the light-emitting layer EL may be reduced. Therefore, in some cases, the display module DM may omit the polarizer to improve luminous efficiency and reduce power consumption for displaying a specific brightness.

[0148] Furthermore, as described above, according to the embodiment, when the polarizer is not formed on the front surface of the display panel DP, the pixel defining layer PDL may include a black colorant, and a light-shielding pattern 310 and a plurality of color filters 320 may be formed in the anti-reflective layer ARL. Accordingly, even when external light enters the interior, the light reflected from the upper surface of the first electrode AE ​​or the side surface of the light-emitting opening PDL-OP of the pixel defining layer PDL can be reduced, and color reproduction and display quality can be improved.

[0149] Figure 7A and Figure 7B These are cross-sectional views of the display module DM according to an embodiment of the present invention. Figure 7A and Figure 7B The diagrams show the following along Figure 4 The cross section of the display module DM is taken from line II-II'.

[0150] For the sake of brevity, omissions will be made. Figure 7A and Figure 7B Regarding the above reference Figure 4 and Figure 6 The description of the construction is the same as the description of the construction, and will refer to Figure 4 and Figure 6 The description.

[0151] Figure 7A and Figure 7B The illustrated module DM includes multiple light-emitting areas LA-R, LA-G, and LA-B, as well as a non-light-emitting area NLA adjacent to the multiple light-emitting areas LA-R, LA-G, and LA-B. The non-light-emitting area NLA can define the boundaries between the light-emitting areas LA-R, LA-G, and LA-B.

[0152] The luminescent areas LA-R, LA-G, and LA-B can be associated with the pixel PX (see...). Figure 3 Set them one-to-one. Pixel PX (see...) Figure 3 Each of them includes a light-emitting element LD, and the light-emitting regions LA-R, LA-G, and LA-B can be regions in which light formed from the light-emitting element LD is emitted.

[0153] The light-emitting element (LD) may include a first light-emitting element LD1 emitting light of a first color, a second light-emitting element LD2 emitting light of a second color different from the first color, and a third light-emitting element LD3 emitting light of a third color different from the first and second colors. The first light-emitting element LD1, the second light-emitting element LD2, and the third light-emitting element LD3 are configured to correspond to the first light-emitting area LA-R, the second light-emitting area LA-G, and the third light-emitting area LA-B, respectively. In an embodiment, the first color may be red, the second color may be green, and the third color may be blue.

[0154] The first light-emitting element LD1, the second light-emitting element LD2, and the third light-emitting element LD3 may each include a first electrode AE1, AE2, and AE3, a light-emitting layer EL1, EL2, and EL3, and a second electrode CE.

[0155] The pixel limiting layer (PDL) can define a first light-emitting opening (PDL-OP1) that exposes the first electrode AE1 of the first light-emitting element LD1, a second light-emitting opening (PDL-OP2) that exposes the first electrode AE2 of the second light-emitting element LD2, and a third light-emitting opening (PDL-OP3) that exposes the first electrode AE3 of the third light-emitting element LD3.

[0156] The plurality of color filters 320 may include a first color filter CF-R configured to overlap with the first light-emitting element LD1, a second color filter CF-G configured to overlap with the second light-emitting element LD2, and a third color filter CF-B configured to overlap with the third light-emitting element LD3.

[0157] The opening 260-OP can be defined in the sensor inorganic layer 260, and the opening 260-OP can include a first opening 260-OP1, a second opening 260-OP2 and a third opening 260-OP3.

[0158] The cavity 250-CVT, including the first cavity 250-CVT1 extending from the first opening 260-OP1, the second cavity 250-CVT2 extending from the second opening 260-OP2, and the third cavity 250-CVT3 extending from the third opening 260-OP3, can be defined in the sensor organic layer 250.

[0159] In this embodiment, the refractive index of the sensor organic layer 250 may be less than that of the corresponding first color filter CF-R and third color filter CF-B, but greater than that of the second color filter CF-G. Due to the difference between the refractive index of the sensor organic layer 250 and the refractive indices of the plurality of color filters 320, the shapes of the first opening 260-OP1 and the third opening 260-OP3 may differ from the shape of the second opening 260-OP2.

[0160] According to an embodiment of the present invention, the opening 260-OP may include a first opening 260-OP1 that overlaps with the first light-emitting opening PDL-OP1. The area of ​​the first opening 260-OP1 may be larger than the area of ​​the first light-emitting region LA-R, but is not limited thereto.

[0161] The refractive index of the first color filter CF-R can be greater than the refractive index of the sensor organic layer 250, and the first opening 260-OP1, which overlaps with the central region of the first electrode AE1, can be confined in the sensor inorganic layer 260.

[0162] When pressure is applied to the input sensor IS, the sensor inorganic layer 260 can disperse the stress transmitted from the external pressure to the sensor organic layer 250 and the second sensor conductive layer 240 disposed below the sensor inorganic layer 260. Furthermore, since the opening 260-OP is defined within the sensor inorganic layer 260, cracks that may occur during bending, folding, and rolling can be prevented, and the stress applied to the entire sensor inorganic layer 260 can be reduced. Therefore, the resistance to pressure shocks and the durability of the display device can be improved.

[0163] According to an embodiment of the present invention, a first cavity 250-CVT1 connected to a first opening 260-OP1 can be defined within a sensor organic layer 250. The first cavity 250-CVT1 defined within the sensor organic layer 250 can be referred to as an engraved pattern or a recessed pattern. The sensor organic layer 250 may include a bottom surface CVT1-FS and a side surface CVT1-SS extending from the bottom surface CVT1-FS to form an acute angle θ2, the bottom surface CVT1-FS and the side surface CVT1-SS defining the first cavity 250-CVT1. The side surface CVT1-SS of the first cavity 250-CVT1 can be formed as a sloped surface. Furthermore, the central region of the first electrode AE1 may overlap with the bottom surface CVT1-FS of the first cavity 250-CVT1.

[0164] The first color filter CF-R can be configured to overlap with the first light-emitting element LD1 and can be disposed within the first opening 260-OP1 and the first cavity 250-CVT1. The first color filter CF-R can transmit only light of a specific color from the light generated by the first light-emitting element LD1, and thus can further improve color reproduction.

[0165] In the light generated from the first light-emitting element LD1, light passing through the side surface CVT1-SS of the first cavity 250-CVT1 can be refracted due to the difference in refractive index between the sensor organic layer 250 and the first color filter CF-R. For example, when emitting light with a wavelength of approximately 630 nm, the refractive index of the sensor organic layer 250 can be approximately 1.53, and the refractive index of the first color filter CF-R can be approximately 1.67. Since the refractive index of the sensor organic layer 250 is less than that of the first color filter CF-R, the angle of refraction at the first color filter CF-R can be reduced compared to the angle of incidence at the side surface CVT1-SS of the first cavity 250-CVT1. In other words, since light passing through the side surface CVT1-SS of the first cavity 250-CVT1 can be refracted towards the first light-emitting area LA-R, the overall luminous efficiency can be improved, and the brightness of the display module DM can be increased.

[0166] According to an embodiment of the present invention, the opening 260-OP may further include a second opening 260-OP2 that does not overlap with the second light-emitting opening PDL-OP2 but overlaps with the pixel defining layer PDL. In an embodiment, the second opening 260-OP2 may surround the second light-emitting element LD2 in a plan view.

[0167] The refractive index of the second color filter CF-G can be less than that of the organic layer 250 of the sensor, and the second opening 260-OP2 can have an annular shape in the plan view.

[0168] In an embodiment, the sensor inorganic layer 260 may include a first portion 260-1 disposed in the region surrounded by the second opening 260-OP2 and a second portion 260-2 disposed outside the second opening 260-OP2. The first portion 260-1 and the second portion 260-2 are spaced apart from the second opening 260-OP2, which has an annular shape. The central region of the second light-emitting element LD2 may overlap with the first portion 260-1. A plan view of the sensor inorganic layer 260 will be referenced later. Figures 8A to 8D Describe the details of Part 1 260-1 and Part 2 260-2.

[0169] A second cavity 250-CVT2 connected to the second opening 260-OP2 may be defined within the sensor organic layer 250. The second cavity 250-CVT2 defined within the sensor organic layer 250 may define an embossed pattern or a raised pattern. The sensor organic layer 250 may include a bottom surface and a side surface extending from the bottom surface to form an acute angle θ1, the bottom surface and the side surface defining the second cavity 250-CVT2. In some embodiments, the inclination of the side surface of the second cavity 250-CVT2 is the same as the inclination of the side surface CVT1-SS of the first cavity 250-CVT1 (θ1 = θ2), but embodiments of the present invention are not necessarily limited thereto.

[0170] In the light generated from the second light-emitting element LD2, light passing through the side surface of the second cavity 250-CVT2 can be refracted due to the difference in refractive index between the sensor organic layer 250 and the second color filter CF-G. For example, when emitting light with a wavelength of approximately 550 nm, the refractive index of the sensor organic layer 250 can be approximately 1.54, and the refractive index of the second color filter CF-G can be approximately 1.52. Since the refractive index of the sensor organic layer 250 is greater than that of the second color filter CF-G, the angle of refraction at the second color filter CF-G can be increased compared to the angle of incidence at the side surface of the second cavity 250-CVT2. Because the light passing through the side surface of the second cavity 250-CVT2 can be refracted towards the second light-emitting area LA-G, the overall luminous efficiency can be improved, and thus the brightness of the display module DM can be increased.

[0171] In an embodiment, opening 260-OP may include a third opening 260-OP3 overlapping with a third light-emitting opening PDL-OP3. A third cavity 250-CVT3 connected to the third opening 260-OP3 may be defined within the sensor organic layer 250. In the light formed from the third light-emitting element LD3, light passing through the side surface CVT3-SS of the third cavity 250-CVT3 may be refracted due to the difference in refractive index between the sensor organic layer 250 and the third color filter CF-B. For example, when emitting light with a wavelength of approximately 450 nm, the refractive index of the sensor organic layer 250 may be approximately 1.55, and the refractive index of the third color filter CF-B may be approximately 1.61. Since the refractive index of the sensor organic layer 250 is less than that of the third color filter CF-B, the angle of refraction at the third color filter CF-B may be reduced compared to the angle of incidence at the side surface of the third cavity 250-CVT3. Since light passing through the side surface of the third cavity 250-CVT3 can be refracted toward the third light-emitting area LA-B, the overall luminous efficiency can be improved, and thus the brightness of the display module DM can be increased.

[0172] refer to Figure 7A The third color filter CF-B can be configured to overlap with the third light-emitting element LD3. Furthermore, the third color filter CF-B can overlap with the pixel-defining layer PDL, and color openings CF-B_OP1 and CF-B_OP2 can be defined to correspond to the first light-emitting element LD1 and the second light-emitting element LD2, respectively. A portion of the third color filter CF-B can overlap with a portion of the first color filter CF-R, and a portion of the third color filter CF-B can overlap with a portion of the second color filter CF-G. That is, the third color filter CF-B can be located between the first color filter CF-R and the pixel-defining layer PDL, and between the second color filter CF-G and the pixel-defining layer PDL.

[0173] As multiple color filters 320 overlap with the pixel-defining layer PDL, the overlapping portion can act as a light-shielding pattern 310 to block unwanted light (see...). Figure 6 This also improves color reproduction.

[0174] refer to Figure 7BThe anti-reflective layer ARL may include a light-shielding pattern 310 overlapping with the pixel-defining layer PDL between the openings 260-OP and a plurality of color filters 320 located on the light-shielding pattern 310. The plurality of color filters 320 may also fill the cavity 250-CVT. The light-shielding pattern openings 310-OP connected to the openings 260-OP of the sensor inorganic layer 260 may be defined within the light-shielding pattern 310. Accordingly, since the light-shielding pattern 310 can control the path of light to block unwanted light, light caused by unwanted reflections can be absorbed or blocked, thereby improving color reproduction.

[0175] Figure 8A , Figure 8B , Figure 8C and Figure 8D These are enlarged plan views of a portion of the sensor inorganic layer 260 according to an embodiment of the present invention.

[0176] Let's refer to each other. Figure 7A and Figure 8A Although not illustrated in the plan view, multiple color filters 320 overlapping with the sensor inorganic layer 260 can be positioned outside the opening 260-OP of the sensor inorganic layer 260. Also see reference... Figure 7B and Figure 8A Although not illustrated in the plan view, the multiple color filters 320 and light-shielding pattern 310 overlapping with the sensor inorganic layer 260 can be further disposed outside the opening 260-OP of the sensor inorganic layer 260. The above can also be applied to... Figure 8B , Figure 8C and Figure 8D And omissions and references Figure 7A and Figure 7B The descriptions of the same constructions are repeated to avoid redundancy. For identical parts, please refer to... Figure 7A and Figure 7B The description.

[0177] In this embodiment, the refractive indices of the first color filter CF-R and the third color filter CF-B are greater than the refractive index of the sensor organic layer 250, and the refractive index of the second color filter CF-G is less than the refractive index of the sensor organic layer 250. Accordingly, the sensor inorganic layer 260 may define a first opening 260-OP1 overlapping with the first light-emitting area LA-R indicated by the dashed line, a second opening 260-OP2 located outside the second light-emitting area LA-G indicated by the dashed line, and a third opening 260-OP3 overlapping with the third light-emitting area LA-B indicated by the dashed line.

[0178] In the plan view, the first opening 260-OP1 and the third opening 260-OP3 may each have a circular shape, and the second opening 260-OP2 may have an annular shape. However, the shapes are not limited to these. For example, the first opening 260-OP1 and the third opening 260-OP3 may each have a polygonal shape, and the second opening 260-OP2 may have a polygonal shape that surrounds or frames the first portion 260-1.

[0179] In an embodiment, in a plan view, the area of ​​the first opening 260-OP1 can be larger than the area of ​​the second opening 260-OP2 and smaller than the area of ​​the third opening 260-OP3. However, the relative size of the openings 260-OP is not limited to this and can vary depending on the light-emitting area.

[0180] The sensor inorganic layer 260 may include a first portion 260-1 disposed inside the second opening 260-OP2 and a second portion 260-2 disposed outside the second opening 260-OP2. That is, the second portion 260-2 may extend continuously between the openings 260-OP1 and may also include a portion disposed outside the first opening 260-OP1. Since the second portion 260-2 of the sensor inorganic layer 260 has a monolithic shape, stress caused by external pressure can be dispersed, and impact resistance can be improved.

[0181] refer to Figure 8B Apart from the failure to form a second opening 260-OP2, Figure 8B The structure and Figure 8A The structures are the same. Figure 8B The refractive index of the second color filter CF-G can be the same as that of the organic layer 250 of the sensor. Accordingly, a second opening 260-OP2 corresponding to the second light-emitting element LD2 is not formed (see...). Figure 7A ), and no second cavity 250-CVT2 was formed (see Figure 7A Since the light generated from the second light-emitting element LD2 has the same angle of refraction and angle of incidence in the sensor organic layer 250 and the second color filter CF-G, the light can propagate in a straight line.

[0182] refer to Figure 8C Except for the first opening 260-OP1 and the third opening 260-OP3, which can each be formed into a ring shape like the second opening 260-OP2, Figure 8C The structure and Figure 8A They have the same structure. (See reference) Figure 8CSince the refractive index of each of the first color filter CF-R and the third color filter CF-B is less than the refractive index of the sensor organic layer 250, the corresponding openings and cavities can each be formed into annular shapes. Accordingly, the first portion 260-1 of the sensor inorganic layer 260 can be formed to overlap with the first light-emitting area LA-R and the third light-emitting area LA-B.

[0183] refer to Figure 8D Similar to the first opening 260-OP1 and the third opening 260-OP3, the second opening 260-OP2, corresponding to the second light-emitting area LA-G, can also have a circular shape. Because... Figure 8D The refractive index of the second color filter CF-G can be greater than that of the organic layer 250 of the sensor, thus forming a second opening 260-OP2 that overlaps with the second light-emitting region LA-G.

[0184] Figure 9A and Figure 9B These are enlarged cross-sectional views of a portion of the display module DM according to an embodiment of the present invention.

[0185] Figure 9A and Figure 9B The diagram shows a cross-sectional view of the sensor inorganic layer 260 and sensor organic layer 250, which are respectively defined by the first opening 260-OP1 and the first cavity 250-CVT1.

[0186] Can be measured Figure 9A The depth h1 of the first cavity 250-CVT1 in the cavity. Figure 9A Depth h1 is described as the distance between the upper surface of the sensor organic layer 250 and the bottom surface CVT1-FS. This distance can be measured at the center of the bottom surface CVT1-FS using extrapolation of the upper surface of the sensor organic layer 250. The first cavity 250-CVT1 can have a depth h1 of approximately 0.5 μm to approximately 3.0 μm.

[0187] Figure 9B The depth h2 of the first cavity 250-CVT1 in the cavity can be greater than Figure 9A The depth h1 in the cavity. For example, as the depth of the first cavity 250-CVT1 increases, the side surface CVT1-SS of the first cavity 250-CVT1 can be extended. Accordingly, since the light passing through the side surface CVT1-SS can increase, the light refracted toward the light-emitting region LA can also increase. Therefore, luminous efficiency and brightness can be improved.

[0188] like Figure 9A and Figure 9BAs shown, the distance between the light-emitting region LA and the edge of the side surface CVT1-SS can be defined as distance d. As used herein, "edge of side surface CVT1-SS" refers to the point where the side surface CVT1-SS of the first cavity 250-CVT1 intersects with the bottom surface CVT1-FS. Distance d is also the distance between the edge of the light-emitting opening PDL-OP and the edge of the side surface CVT1-SS. As used herein, "edge of light-emitting opening PDL-OP" refers to the point where the sidewall of the light-emitting opening PDL-OP is closest to the circuit layer DP-CL. In the plan view, the distance d between the edge of the light-emitting region LA and the edge of the side surface CVT1-SS can be from 0 μm to approximately 2.5 μm.

[0189] The distance d in the plane between the edge of the light-emitting opening PDL-OP and the edge of the side surface CVT1-SS of the first cavity 250-CVT1 is within the range described above. Light from the light-emitting element LD can be incident on the side surface CVT1-SS of the first cavity 250-CVT1, and therefore the light can be more easily refracted into the light-emitting area LA, thereby improving the luminous efficiency.

[0190] Table 1 below shows the improvement rate of luminous efficiency based on the depth h1 or h2 of the first cavity 250-CVT1 and the distance d between the edge of the light-emitting opening PDL-OP and the edge of the side surface CVT1-SS of the first cavity 250-CVT1. Measurements were taken using a display device including a display module without defined openings as a reference. Figure 9A and Figure 9B The improvement rate of luminous efficiency of the display device of the display module DM.

[0191] [Table 1] Luminous efficiency as a function of d and h1 or h2

[0192]

[0193] Referring to Table 1, it can be seen that the luminous efficiency increases with the increase of the depth of the first cavity 250-CVT1. However, when the depth becomes greater than a certain value, the conductive pattern protected by the sensor organic layer 250 may be exposed, which may lead to a deterioration in durability. As the distance d between the edge of the light-emitting opening PDL-OP and the edge of the side surface CVT1-SS of the first cavity 250-CVT1 increases, light from the light-emitting element LD can be incident on the side surface CVT1-SS of the first cavity 250-CVT1, thus improving the luminous efficiency. However, when the distance between the edge of the light-emitting opening PDL-OP and the edge of the side surface CVT1-SS of the first cavity 250-CVT1 exceeds approximately 2.5 μm, the width of the first opening 260-OP1 (measured in the plan view) may become too large and reduce the total area of ​​the sensor inorganic layer 260. Therefore, the shock resistance decreases.

[0194] Figure 10A and Figure 10B These are enlarged plan views of a portion of the sensor inorganic layer 260 according to an embodiment of the present invention.

[0195] Figure 10A The diagram illustrates the opening 260-OP of the sensor's inorganic layer 260 relative to the first light-emitting area LA-R, the second light-emitting area LA-G, and the third light-emitting area LA-B, as well as the cavity 250-CVT (see...). Figure 7A The shape of the offset. As shown above... Figure 9A and Figure 9B As described above, the light-emitting area LA and the cavity 250-CVT (see...) Figure 7A The distance between them can be changed, and the central region of the luminescent area (LA) can also be shifted. Accordingly, in the cavity 250-CVT (see... Figure 7A Dispersion can occur within ).

[0196] like Figure 10B As shown, based on the area and width of the opening 260-OP in some of the light-emitting areas among the first light-emitting area LA-R, the second light-emitting area LA-G, and the third light-emitting area LA-B, in the cavity 250-CVT (see... Figure 7A Dispersion can also occur within ( ). For example, with Figure 10B The area and width of the third opening 260-OP3 are reduced, and the corresponding cavity also has a reduced area and width. Accordingly, the area of ​​the second part 260-2 of the sensor inorganic layer 260 can be increased, and thus the impact resistance can be improved.

[0197] According to embodiments of the present invention, the display device and electronic device include a sensor organic layer and a sensor inorganic layer disposed on the sensor organic layer and defining openings therein, thereby preventing the formation of progressive dark spots in the display device and electronic device due to cracks appearing in the input sensor and crack propagation. Therefore, the shock resistance and durability of the display device and electronic device can be improved.

[0198] Furthermore, according to embodiments conceived in this invention, light from the side surfaces of the display device and electronic device is refracted and thus can be totally reflected as it passes through the cavity of the sensor's organic layer, thereby making it possible to improve the luminous efficiency of the front side.
