Detailed Implementation

[0021] The present invention will be described in detail below with reference to specific embodiments and accompanying drawings. To make the invention clearer and easier to understand, the accompanying drawings are simplified schematic diagrams, and the elements therein may not be drawn to scale. Furthermore, the number and dimensions of the elements in the drawings are merely illustrative and are not intended to limit the scope of the invention.

[0022] Throughout this specification and the appended claims, certain terms are used to refer to specific elements. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same elements, and this document is not intended to distinguish between elements that have the same function but different names. In the following specification and claims, words such as "containing" and "comprising" are open-ended terms and should therefore be interpreted as "containing but not limited to...".

[0023] The use of ordinal numbers, such as "first," "second," etc., in the specification and claims to modify elements of a claim does not in itself imply or represent any prior ordinal number of the claimed element, nor does it represent the order of one claimed element with another or the order of manufacture. The use of these ordinal numbers is solely to clearly distinguish one claimed element with a given name from another claimed element with the same name. Therefore, a first element mentioned in the specification may be referred to as a second element in the claims.

[0024] The directional terms used in the following embodiments, such as up, down, left, right, front, or back, are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. It should be understood that elements specifically described or illustrated may exist in various forms well known to those skilled in the art. In this document, when an element is referred to as "overlapping" with another element, it should be understood that the element partially or completely overlaps with the other element.

[0025] Furthermore, when an element or membrane is referred to as being on or above another element or membrane, or as being connected to another element or membrane, it should be understood that the element or membrane is directly located on or directly connected to the other element or membrane, or that there may be other elements or membranes (indirectly) between them. Conversely, when an element or membrane is referred to as being "directly" on or "directly connected" to another element or membrane, it should be understood that there are no inserted elements or membranes between them.

[0026] In this text, the terms "approximately," "substantially," and "roughly" typically indicate a range within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value. The given quantity is an approximate quantity, meaning that the meaning of "approximately," "substantially," or "roughly" can still be implied even without specific mention of these terms.

[0027] It should be understood that the features described below can be replaced, recombined, or mixed in several different embodiments to complete other embodiments without departing from the spirit of the invention. Features between embodiments can be arbitrarily mixed and combined as long as they do not violate the spirit of the invention or conflict with it.

[0028] In this invention, the length, thickness and width can be measured using an optical microscope, an electron microscope or other methods, but are not limited thereto.

[0029] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It is understood that these terms, for example, as defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant art and this invention, and should not be interpreted in an idealized or overly formal manner, unless specifically defined in the embodiments of this invention.

[0030] In this invention, the electronic device may have a display function and may selectively include light sensing, image sensing, touch control, antenna, other suitable functions, or combinations thereof, but is not limited thereto. In some embodiments, the electronic device may include a splicing device, but is not limited thereto. The electronic device may include liquid crystal molecules (LCmolecule), light-emitting diodes (LEDs), or quantum dot (QD) materials, fluorescent materials, phosphorescent materials, other suitable materials, or combinations thereof, but is not limited thereto. Light-emitting diodes may include, for example, organic light-emitting diodes (OLEDs), micro-LEDs, sub-millimeter light-emitting diodes (mini-LEDs), or quantum dot light-emitting diodes (QLEDs or QDLEDs), but are not limited thereto. Furthermore, the electronic device may be, for example, a color display device, a monochrome display device, or a grayscale display device. The shape of the electronic device may be, for example, rectangular, circular, polygonal, a shape with curved edges, a curved surface, or other suitable shapes. The electronic device may optionally have peripheral systems such as a driving system, a control system, a light source system, a shelving system, etc.

[0031] Please refer to Figure 1 The diagram shown is a top view of an electronic device according to an embodiment of the present invention. Figure 1As shown, the electronic device 1 provided in this embodiment may include a display panel 10 and a light sensor 12, wherein the display panel 10 can be used to display images, and the light sensor 12 can be used to detect light. For example, the light sensor 12 can be used to detect visible light or invisible light. Invisible light may include, for example, infrared, ultraviolet, or other suitable light. In some embodiments, the light sensor 12 can be used to detect images, for example, including an image sensor or multiple light sensing units. The image sensor may include, for example, a photographic element, but is not limited thereto. The light sensing unit may include, for example, a photodiode, a phototransistor, or other suitable light sensing element. In some embodiments, the light sensor 12 may be replaced with elements that have other functions.

[0032] The display panel 10 is further described below. Figure 1 As shown, the display panel 10 may include a substrate 14, wherein the substrate 14 may have a first display area DR1, and the light sensor 12 may be disposed in the first display area DR1 in the top view direction TD of the display panel 10. In some embodiments, the substrate 14 may selectively have a second display area DR2, but is not limited thereto. For example, in the top view direction TD of the display panel 10, the second display area DR2 may surround the first display area DR1 or be disposed on at least one side of the first display area DR1. It should be noted that, hereinafter, the first display area DR1 refers to the area in the top view direction TD that overlaps with the sensing area of ​​the light sensor 12 that can detect light, while the second display area DR2 is the area in the top view direction TD that is located outside the first display area DR1 and overlaps with the light-emitting unit 20 (described in detail below). In some embodiments, the substrate 14 may also selectively have a peripheral area PR disposed outside the first display area DR1 and the second display area DR2 for disposing of peripheral elements or other suitable elements in the display panel 10, but is not limited thereto. The substrate 14 may include a transparent substrate, or may include a flexible or rigid substrate. For example, substrate 14 may include glass, quartz, plastic or other substrates, but is not limited thereto.

[0033] For ease of explanation, Figure 1 Further, the right side shows an enlarged schematic diagram of region R1 of the display panel 10 in the first display area DR1 in the top view TD, with the structure in region R1 representing the structure of the display panel 10 corresponding to the first display area DR1. The left side shows an enlarged schematic diagram of region R2 of the display panel 10 in the second display area DR2 in the top view TD, with the structure in region R2 representing the structure of the display panel 10 corresponding to the second display area DR2. However, this invention is not limited thereto. Figure 1As shown in the enlarged schematic diagram of the central region R1, the display panel 10 may further include multiple light-emitting units 16 and multiple grid units 18, and the light-emitting units 16 and grid units 18 may be disposed in the first display region DR1 in the top view direction TD of the display panel 10. Figure 1 In this paper, a single grid cell 18 is taken as an example, but the number of grid cells 18 in this invention is not limited to this, and can be multiple, for example... Figure 5 As shown. Further, the first display area DR1 may include a light-transmitting area TR, and the light-emitting unit 16 is located outside the light-transmitting area TR in the top view direction TD of the display panel 10. It should be noted that in this invention, the light-transmitting area TR refers to the area located outside the light-emitting unit 16, and the term "area located outside an element" means the area that does not overlap with the element in the top view direction TD of the display panel 10. In some embodiments, the top view direction TD of the display panel 10 may, for example, be the upper surface of the substrate 14 used to mount the light-emitting unit 16 (e.g., Figure 2 The normal direction of the upper surface 14a) of the substrate 14 shown.

[0034] Specifically, such as Figure 1 As shown in the enlarged schematic diagram of the central region R1, the grid unit 18 may have a grid frame 18a, and the grid frame 18a may form multiple grid openings 18b. It should be noted that the grid openings 18b do not overlap with any of the light-emitting units 16 in the top-view direction TD of the display panel 10. The light-transmitting area TR may overlap with at least one grid opening 18b in the top-view direction TD of the display panel 10. Through this design, the display panel 10 can have higher light transmittance in the portion corresponding to the grid opening 18b. Therefore, the light sensor 12 corresponding to the first display area DR1 can detect higher intensity light through the grid openings 18b, thereby improving the quality of the detected image.

[0035] In some embodiments, the grid frame 18a may also form a plurality of grid openings 18c, which may overlap with at least one light-emitting unit 16 or at least one sub-pixel. Figure 1 As shown, a grid opening 18c can overlap multiple light-emitting units 16 or multiple sub-pixels in the top view TD of the display panel 10. Figure 1 In some embodiments, the light-emitting unit 16 may include light-emitting units 16a, 16b, and 16c, which are used to generate light of different colors and serve as sub-pixels of different colors, but are not limited thereto. For example, light-emitting units 16a, 16b, and 16c may be used to generate blue, green, and red light, respectively, but are not limited thereto. Figure 1The embodiment uses the pixel arrangement of PenTile as an example. Therefore, a pixel PX corresponding to the first display area DR1 may include one light-emitting unit 16a, two light-emitting units 16b, and one light-emitting unit 16c, and a grid opening 18c may overlap with a pixel, but is not limited thereto. In some embodiments, the number, color, and arrangement of the light-emitting units 16 forming the pixel PX can be adjusted according to actual needs. In some embodiments, the grid opening 18 may also overlap with a light-emitting unit 16 or a sub-pixel, for example... Figure 5 As shown.

[0036] exist Figure 1 In one embodiment, mesh openings 18b and 18c may be sequentially and alternately arranged on a horizontal direction HD1 and / or another horizontal direction HD2. Horizontal direction HD1 is different from horizontal direction HD2. In one embodiment, horizontal direction HD1 may be, for example, perpendicular to horizontal direction HD2 and parallel to the upper surface of substrate 14 (e.g., Figure 2 The upper surface 14a of the substrate 14 shown is not limited to this. In other words, since the grid opening 18c is an opening that overlaps with the light-emitting unit 16, while the grid opening 18b is an opening that does not overlap with the light-emitting unit 16, the distance between pixels PX or sub-pixels can be increased through the above arrangement, thereby reducing the resolution of the portion of the display panel 10 corresponding to the first display area DR1, thereby increasing the area of ​​the light-transmitting area TR of the first display area DR1 and improving the light transmittance of the display panel 10 corresponding to the first display area DR1.

[0037] like Figure 1 As shown in the enlarged schematic diagram of the central region R2, the display panel 10 may further include multiple light-emitting units 20 and multiple grid units 22, wherein the light-emitting units 20 and grid units 22 are disposed in the second display region DR2 in the top view direction TD of the display panel 10. A grid unit 22 may include multiple grid openings 22b, and a grid opening 22b may overlap with at least one light-emitting unit 20 in the top view direction TD. Specifically, the grid unit 22 may have a grid frame 22a, and the grid frame 22a may form multiple grid openings 22b. The grid openings 22b may overlap with at least one light-emitting unit 20 or at least one sub-pixel. Figure 1 As shown, a grid opening 22b can overlap with multiple light-emitting units 20 in the top view direction TD of the display panel 10. In some embodiments, the grid opening 22b can also overlap with a light-emitting unit 20 or a sub-pixel, and is not limited thereto. Figure 1In some embodiments, the light-emitting unit 20 may include light-emitting units 20a, 20b, and 20c, which are used to generate light of different colors and serve as sub-pixels of different colors, but are not limited thereto. For example, light-emitting units 20a, 20b, and 20c may be the same as light-emitting units 16a, 16b, and 16c, but are not limited thereto. The arrangement of light-emitting units 20a, 20b, and 20c may be, for example, the same as the arrangement of light-emitting units 16a, 16b, and 16c, but is not limited thereto. A pixel PX corresponding to the second display area DR2 may include one light-emitting unit 20a, two light-emitting units 20b, and one light-emitting unit 20c. The arrangement of pixel PX may include, for example, a PenTile arrangement or other suitable arrangements. It should be noted that there may be no opening between any two adjacent grid openings 22b that does not overlap with the light-emitting unit 20. In other words, the resolution of the portion of display panel 10 corresponding to the second display area DR2 can be greater than the resolution of the portion of display panel 10 corresponding to the first display area DR1. The resolution of the portion of display panel 10 corresponding to the first display area DR1 can, for example, be half the resolution of the portion of display panel 10 corresponding to the second display area DR2.

[0038] like Figure 1 As shown, grid frames 18a and 22a may have conductive properties, allowing grid cells 18 and 22 to serve as sensing electrodes for touch sensing elements. For example, grid frames 18a and 22a may comprise a metallic material, such as molybdenum, aluminum, or copper. Grid frames 18a and 22a may be formed, for example, from the same metal layer, but are not limited thereto. Grid frames 18a and 22a may be, for example, a single-layer or multi-layer structure. When grid frames 18a and 22a are multi-layer structures, they may, for example, comprise a molybdenum / aluminum / molybdenum or molybdenum / copper / molybdenum stacked structure.

[0039] Figure 2 The electronic device shown is an embodiment of the present invention. Figure 1 A schematic diagram of the cross-sections A-A' and B-B'. Figure 2 The cross-sectional schematic diagram shown is Figure 1 An example of electronic device 1, and Figure 1 The cross-sectional schematic diagram of the electronic device is not based on Figure 2 The structure shown is for reference only and can be adjusted according to the type of display panel and touch sensing element. For example... Figure 2As shown, the light sensor 12 may be disposed under the first display area DR1 of the substrate 14, but is not limited thereto. Additionally, the display panel 10 may include a circuit layer 24 disposed between the light-emitting unit 16 and the substrate 14, and between the light-emitting unit 20 and the substrate 14. For example, the circuit layer 24 may include a plurality of driving elements 26 for driving the light-emitting units 16 and 20 to generate light. The driving elements 26 may include, for example, thin-film transistors or other suitable transistors, but are not limited thereto. In some embodiments, the circuit layer 24 may include, in addition to the driving elements 26, switching elements (not shown), signal lines (not shown), and other suitable elements. The signal lines may include, for example, data lines, scan lines, shared lines, or other required signal lines.

[0040] exist Figure 2 In this embodiment, the driving element 26 and the switching element may be, for example, top-gate type thin-film transistors. In this case, the circuit layer 24 may include a semiconductor layer 28, an insulating layer IN1, a metal layer M1, an insulating layer IN2, a metal layer M2, an insulating layer IN3, and a planarization layer 30. The semiconductor layer 28 is disposed on the substrate 14 and may include multiple semiconductor blocks 28a as channel layers for the driving element 26. The insulating layer IN1 may be disposed on the semiconductor layer 28 as a gate insulating layer for the driving element 26. The metal layer M1 may be disposed on the insulating layer IN1 and includes multiple gates G of the driving element 26, respectively disposed on corresponding semiconductor blocks 28a. The insulating layer IN2 may be disposed on the metal layer M1, and the insulating layers IN1 and IN2 may have multiple vias. Metal layer M2 is disposed on insulating layer IN2 and includes multiple source (drain) electrodes SD1 and multiple drain (source) electrodes SD2 of driving elements 26. The source (drain) electrodes SD1 and SD2 can be electrically connected to the corresponding semiconductor block 28a through vias in insulating layer IN2 and insulating layer IN1, respectively. Insulating layer IN3 and planarization layer 30 can be sequentially disposed on metal layer M2 and have multiple vias. Light-emitting unit 16 and light-emitting unit 20 can be electrically connected to the corresponding driving element 26 through vias in planarization layer 30 and insulating layer IN3, respectively. Metal layer M1 and metal layer M2 can, for example, include aluminum, molybdenum nitride, copper, titanium, other suitable materials, or combinations thereof, but are not limited thereto. The structure of circuit layer 24 of the present invention is not limited thereto and can be adjusted according to the type of driving element 26 and switching element. In some embodiments, the driving element 26 and switching element can also be, for example, a bottom-gate thin-film transistor, or can be changed to a dual-gate transistor or other suitable transistor as needed.

[0041] like Figure 2As shown, the display panel 10 may further include an insulating layer IN4 disposed on the circuit layer 24, wherein the insulating layer IN4 may include multiple openings OP1, and the light-emitting unit 16 and the light-emitting unit 20 may be disposed corresponding to the openings OP1. Figure 2 In this embodiment, the light-emitting unit 16 and the light-emitting unit 20 include an organic light-emitting diode (OLED). In this case, the light-emitting unit 16 and the light-emitting unit 20 may each include a first electrode 32, a light-emitting layer 34, and a second electrode 36. The first electrode 32 may be disposed on the planarization layer 30 and spaced apart from each other. An insulating layer IN4 may be disposed on the first electrode 32 and the planarization layer 30, and each first electrode 32 may be exposed by a corresponding opening OP1. Furthermore, each light-emitting layer 34 may be disposed in the corresponding opening OP1 of the insulating layer IN4, and the second electrode 36 may be disposed on each light-emitting layer 34 and extend onto the insulating layer IN4. Figure 2 In some embodiments, the second electrode 36 of the light-emitting unit 16 and the light-emitting unit 20 may be formed from the same conductive layer CL, but is not limited thereto. The first electrode 32 and the second electrode 36 may be, for example, the anode and cathode of an organic light-emitting diode, but are not limited thereto, and may be interchanged. It should be noted that the region of the light-emitting unit 16 and the light-emitting unit 20 may be defined, for example, as the region where the first electrode 32, the light-emitting layer 34, and the second electrode 36 overlap in the top view direction TD, but is not limited thereto.

In some embodiments, the insulating layer IN4 may include, for example, an organic material or other suitable material, but is not limited thereto.

[0042] like Figure 2As shown, the display panel 10 may further include a sealing layer 38 disposed on the light-emitting unit 16 and the light-emitting unit 20 to protect the light-emitting unit 16 and the light-emitting unit 20. The sealing layer 38 may be a single-layer or multi-layer structure, wherein the multi-layer structure may be, for example, a three-layer structure (bottom inorganic layer, middle organic layer, and top inorganic layer), but is not limited thereto. In some embodiments, the sealing layer 38 in the light-transmitting area TR and the sealing layer 38 on the light-emitting unit 16 and the light-emitting unit 20 may be composed of different structures or materials. In some embodiments, the display panel 10 may also selectively include an insulating layer IN5 disposed on the sealing layer 38, but is not limited thereto. The grid frame 18a of the grid unit 18 and the grid frame 22a of the grid unit 20 may be disposed on the insulating layer IN5, and in the top view TD, the grid frame 18a and the grid frame 22a may overlap with the insulating layer IN4. In some embodiments, the insulating layers IN1, IN2, IN3, and IN5 may, for example, comprise silicon oxide, silicon nitride, combinations thereof, or other suitable materials, but are not limited thereto.

[0043] exist Figure 2 In some embodiments, the second electrode 36, the insulating layer IN4, and the circuit layer 24 may have multiple openings OP2, and a sealing layer 38 may be disposed in the openings OP2. The openings OP2 improve the light transmittance of the portion of the display panel 10 corresponding to the openings OP2. Specifically, each opening OP2 may overlap with a corresponding grid opening 18b in the top-view direction TD. In some embodiments, the openings OP2 may not penetrate the circuit layer 24, and the depth of the openings OP2 in the top-view direction TD can be adjusted according to actual needs. In some embodiments, the second electrode 36, the insulating layer IN4, and the circuit layer 24 may also not have openings OP2.

Figure 3 As shown, in some embodiments, a mesh opening 18c may overlap with a light-emitting unit 16, but is not limited thereto. In some embodiments, Figure 3The correspondence between the grid opening 18c and the light-emitting unit 16 shown can also be applied to the above. Figure 1 The correspondence between the grid opening 18c and the light-emitting unit 16 and / or the correspondence between the grid opening 22b and the light-emitting unit 20.

[0046] In some embodiments, such as Figure 3 As shown, the grid frame 18a may have a contour in the top view TD of the display panel 10, and a portion 18a1 of the contour may be arc-shaped. For example, the portion 18a1 of the contour may be located at a corner of one of the grid openings 18b1. In some embodiments, at least one grid opening 18b of at least one grid frame 18a and / or at least one grid opening 18c and / or at least one grid opening 22b of at least one grid frame 22a may have an arc-shaped contour, but is not limited thereto. In some embodiments, at least one grid opening 18b4 of the grid frame 18a may have a polygon (excluding the arc-shaped contour) in the top view TD. For example, the included angle between any two connected sides of the grid opening 18b4 may be greater than 90 degrees, but is not limited thereto. In some embodiments, at least one grid opening 18b of at least one grid frame 18a and / or at least one grid opening 18c and / or at least one grid opening 22b of at least one grid frame 22a may be a polygon, but is not limited thereto. In some embodiments, the arcuate profile and / or polygonal mesh opening 18b may be applied to the mesh opening 18b, mesh opening 18c and / or mesh opening 22b and / or at least one mesh opening described below in the above embodiments.

[0047] In some embodiments, such as Figure 3 As shown, the size of the grid openings 18b can be adjusted according to requirements. For example, within the same unit area, the number of grid openings 18b1, 18b2, and 18b3 can be different. In other words, within the same unit area, the overlap area between the portion of the grid frame 18a corresponding to grid opening 18b1, 18b2, and 18b3 and the light-transmitting area TR can be different, thereby adjusting the light transmittance of the display panel 10. For example, the number of grid openings 18b between two adjacent pixels arranged in the same horizontal direction HD1 or HD2 can be at least one.

[0048] Figure 4 The diagram shown is a top view of a portion of the display panel corresponding to the first display area according to some embodiments of the present invention. For example... Figure 4As shown, the width W1 of grid opening 18b and the width W2 of grid opening 18c can be the same or different. For example, the ratio of the width W1 of one of the grid openings 18b to the width W2 of one of the grid openings 18c can be greater than or equal to 1.01 and less than or equal to 5 (1.01≤W1 / W2≤5), or greater than or equal to 1.01 and less than or equal to 3 (1.01≤W1 / W2≤3). It should be noted that the width W1 of grid opening 18b and the width W2 of grid opening 18c can be obtained in the following way. Taking grid openings 18b5 and 18c1 as an example, firstly, find the dashed line V1 extending along the arrangement direction of grid openings 18b5 and 18c1 (e.g., the horizontal direction HD1), and the dashed line V1 crosses the two opposite sides S1 of grid opening 18b5 and the two opposite sides S2 of grid opening 18c1. Furthermore, find the center point P of one of the sides S1 of grid opening 18b5 and S2 of grid opening 18c1. Taking one of the sides S2 of grid opening 18c1 as an example, the point at half the length of side S2 can be found, which is the center point P. Then, set the dashed line V1 to pass through the center point P. In this case, measuring the length of the dashed line V1 across grid opening 18b5 will give the width W1 of grid opening 18b5, and measuring the length of the dashed line V1 across grid opening 18c1 will give the width W2 of grid opening 18c1. When the width W1 of grid opening 18b5 and the width W2 of grid opening 18c1 are not the same, although the position of the dashed line V1 across side S1 and side S2 may be different during measurement, the ratio of the calculated width W1 of grid opening 18b5 to the width W2 of grid opening 18c1 will always be within the above ratio range.

[0049] In some embodiments, such as Figure 4 As shown, when the width W1 of grid opening 18b5 is different from the width W2 of grid opening 18c1, the width W1 of another grid opening 18b6 can be the same as the width W2 of another grid opening 18c2. The width W1 of grid opening 18b6 and the width W2 of grid opening 18c2 can be obtained, for example, through the dashed line V2, but are not limited thereto. In some embodiments, such as Figure 1 As shown, the width W1 of each grid opening 18b may be the same as the width W2 of each grid opening 18c. In some embodiments, the width W1 of each grid opening 18b may also be different from the width W2 of each grid opening 18c, but the present invention is not limited thereto.

[0050] Figure 5 The diagram shown is a top view of a portion of the display panel corresponding to the first display area and the second display area according to some embodiments of the present invention. Figure 6 The image shows the display panel along... Figure 5 A schematic diagram of the cross-section C-C'. (See diagram below.) Figure 5 As shown, the display panel 10 may include a plurality of grid cells 18. The grid cells 18 may, for example, be arranged on a horizontal direction HD3. The display panel 10 may also include a bridging unit 42 disposed between two adjacent grid cells 18 for electrically connecting the two adjacent grid cells 18. The grid cells 18 and the bridging unit 42 may be electrically connected to form a plurality of electrode strings ES1, wherein the electrode strings ES1 may, for example, extend along the horizontal direction HD3. Figure 5 In one embodiment, the bridging unit 42 may have a strip grid 42a, and the strip grid 42a may include a plurality of grid openings 42b. The grid openings 42b may be arranged in the horizontal direction HD3 and overlap with at least one light-emitting unit 16 in the top view TD. The number and size of the grid openings 42b may be adjusted according to the distance between two adjacent grid units 18.

[0051] like Figure 5 As shown, the display panel 10 may further include a plurality of grid units 44 disposed on the first display area DR1 of the substrate 14, wherein the grid units 44 and the grid units 18 may be arranged in different directions. For example, when the grid units 18 are arranged along the horizontal direction HD3, the grid units 44 may be arranged along the horizontal direction HD4, but are not limited thereto. The horizontal direction HD3 may be different from the horizontal direction HD4. For example, the horizontal direction HD3 may be perpendicular to the horizontal direction HD4, but are not limited thereto. Figure 5 In some embodiments, the horizontal directions HD3 and HD4 may differ from the arrangement directions of the grid openings 18b and 18c (e.g., horizontal directions HD1 or HD2), but are not limited thereto. Furthermore, each grid cell 44 may have a grid frame 44a, and the grid frame 44a may form a plurality of grid openings 44b and a plurality of grid openings 44c, wherein the grid openings 44b overlap with the light-transmitting area TR in the top view direction TD, and the grid openings 44c overlap with at least one light-emitting unit 16 or a sub-pixel in the top view direction TD, but are not limited thereto. In some embodiments, the grid openings 44b may be any of the above embodiments or any of the grid openings 18b described below, and the grid openings 44c may be any of the above embodiments or any of the grid openings 18c described below, and therefore will not be elaborated further here. In some embodiments, taking one grid cell 18 and one grid cell 44 as an example, the grid openings 18b and 44b may have different numbers, and / or the grid openings 18c and 44c may have different numbers. In some embodiments, grid cells 18 and grid cells 44 may have different grid patterns.

[0052] like Figure 5As shown, the display panel 10 may further include a bridging unit 46 disposed between two adjacent grid cells 44 for electrically connecting the two adjacent grid cells 44. The grid cells 44 and the bridging unit 46 may be electrically connected to form multiple electrode strings ES2, wherein the electrode strings ES2 may extend, for example, along the horizontal direction HD4, and the electrode strings ES2 may overlap with the electrode strings ES1 in the top-view direction TD. Figure 5 In this embodiment, the bridging unit 46 may have a strip-shaped grid 46a, and the strip-shaped grid 46a may include a plurality of grid openings 46b, which overlap with at least one light-emitting unit 16 in the top view direction TD. For example, the grid openings 46b may be arranged in the horizontal direction HD4, but are not limited thereto. It should be noted that the bridging unit 46 may overlap with the bridging unit 42 in the top view direction TD, but a dielectric layer (e.g., ...) may be disposed between the bridging unit 46 and the bridging unit 42. Figure 6 The insulating layer IN6 shown is used to electrically insulate the bridging unit 42 from the bridging unit 46. Therefore, the electrode string ES1 can be capacitively coupled to the electrode string ES1, thereby forming a touch sensing element corresponding to the first display area DR1.

[0053] Specifically, such as Figure 6 As shown, the display panel 10 may include insulating layers IN6 and IN7, which are sequentially disposed on insulating layer IN5, and the strip grid 46a of the bridging unit 46 may include a first layer 46a1 and a second layer 46a2. Figure 6In this embodiment, the first layer 46a1 and the strip mesh 42a may be disposed on the insulating layer IN5 and separated from each other, such that the first layer 46a1 and the strip mesh 42a are electrically insulated from each other. For example, the first layer 46a1 and the strip mesh 42a may comprise the same conductive material or be formed of the same conductive layer CL1. The insulating layer IN6 may be disposed on the first layer 46a1 and the strip mesh 42a, and the insulating layer IN6 may have an opening OP3 (or a perforation) exposing a portion of the first layer 46a1. The second layer 46a2 may be disposed on the insulating layer IN6 and extend through the opening OP3 to contact (or electrically connect) the first layer 46a1. The second layer 46a2 may be formed, for example, of the conductive layer CL2. Since the strip mesh 42a is disposed between the insulating layers IN5 and IN6, the second layer 46a2 disposed on the insulating layer IN6 may overlap with the strip mesh 42a in the top view TD to electrically connect adjacent mesh cells 44. In some embodiments, insulating layers IN6 and IN7 may, for example, comprise silicon oxide, silicon nitride, a combination thereof, or other suitable materials, but are not limited thereto. The structures of the stripe grids 42a and 46a of the present invention are not limited to those described above. In some embodiments, the stripe grids 42a and 46a2 may comprise the same or different conductive materials as the second layer 46a2 of the stripe grids 46a. In some embodiments, the second layer 46a2 may also be formed by a conductive layer CL1, and the first layer 46a1 and the stripe grids 42a may be formed by a conductive layer CL2; in other words, the first layer 46a1 may be disposed on the second layer 46a2, without limitation.

[0054] Please continue to refer to this. Figure 5 The second display area DR2. The display panel 10 may also include a plurality of grid units 48 disposed on the display area DR2 of the substrate 14. The grid unit 48 may have a grid frame 48a, and the grid frame 48a may form a plurality of grid openings 48b, wherein the grid openings 48b may overlap with at least one light-emitting unit 20 in the top view TD. Figure 5 In some embodiments, grid cell 48 and grid cell 22 may, for example, have the same grid pattern, but are not limited thereto.

[0055] In addition, such as Figure 5As shown, the display panel 10 may further include a bridging unit 50 and a bridging unit 52. The bridging unit 50 can be electrically connected to adjacent grid units 22, such that grid units 22 and bridging unit 50 can form multiple electrode strings ES3. The bridging unit 52 can be electrically connected to adjacent grid units 48, such that grid units 48 and bridging unit 52 can form multiple electrode strings ES4, and electrode strings ES4 can overlap with electrode strings ES3 in the top-view direction TD. Electrode strings ES3 and electrode strings ES4 can be capacitively coupled, thereby forming a touch sensing element corresponding to the second display area DR2. Therefore, the touch sensing element can be, for example, mutually capacitive, but is not limited thereto. It should be noted that, in order to clearly show the bridging unit 46 and bridging unit 52, Figure 5 and the following text Figure 7 , Figure 8 and Figure 10 The outlines of bridging unit 46 and bridging unit 52 are drawn thicker than those of bridging unit 42 and bridging unit 50, but this invention is not limited thereto.

[0056] exist Figure 5 In the embodiments, electrode strings ES3 and ES4 extend along different directions, for example, along horizontal directions HD3 and HD4, respectively. Bridging unit 50 may include multiple mesh openings 50b, each overlapping at least one light-emitting unit 20 in the top view TD. The mesh openings 50b may be arranged in the horizontal direction HD3, but are not limited thereto. Bridging unit 52 may include multiple mesh openings 52b, each overlapping at least one light-emitting unit 20 in the top view TD. The mesh openings 50b may be arranged in the horizontal direction HD3, and the mesh openings 52b may be arranged in the horizontal direction HD4, but are not limited thereto. Figure 5 In some embodiments, the size of the grid opening 50b may be the same as the size of the grid opening 52b, but is not limited thereto. Depending on the required spacing between adjacent grid cells 22 and adjacent grid cells 48, the number of grid openings 50b in the bridging unit 50 may differ from the number of grid openings 42b in the bridging unit 42, and / or the number of grid openings 52b in the bridging unit 52 may differ from the number of grid openings 46b in the bridging unit 46, but is not limited thereto. In some embodiments, when electrode string ES3 and a corresponding electrode string ES1 are arranged along the same line, electrode string ES3 and the corresponding electrode string ES1 may be electrically connected to each other. Similarly, when electrode string ES4 and a corresponding electrode string ES2 are arranged along the same line, electrode string ES4 and the corresponding electrode string ES2 may be electrically connected to each other.

[0057] Figure 7 The diagram shown is a top view of different portions of the display panel corresponding to the first display area in some embodiments of the present invention. For example... Figure 7As shown in the left portion LP1, the number of grid openings 18b in grid cell 18 and grid openings 44b in grid cell 44 can be the same. For example, grid cell 18 and grid cell 44 can have the same or similar grid patterns. In this case, since the grid openings 18b in grid cell 18 and grid openings 44b in grid cell 44 need to be designed to match the light-emitting unit 16 in the top view direction TD, the distance between adjacent grid cells 18 can be different from the distance between adjacent grid cells 44, but is not limited to this.

[0058] like Figure 7 As shown in the right-hand portion RP1, the grid frame 18a of the grid unit 18 may have a portion P1 corresponding to the grid opening 18b and a portion P2 corresponding to the grid opening 18c, and the width W3 of portion P1 may be greater than the width W4 of portion P2. In some embodiments, the grid frame 44a of the grid unit 44 may have a portion P3 corresponding to the grid opening 44b and a portion P4 corresponding to the grid opening 44c, and the width W5 of portion P3 may be greater than the width W6 of portion P4. The cases where the width W3 of portion P1 is greater than the width W4 of portion P2 and the cases where the width W5 of portion P3 is greater than the width W6 of portion P4 may coexist or one of them may coexist, and at least one of them may be applicable to the grid units and / or grid units in any other embodiment. In some embodiments, the grid units 18 and 44 of the display panel may all adopt Figure 7 The left part LP1 or Figure 7 The right side of RP1 or simultaneously adopts Figure 7 The left side of LP1 and Figure 7 The right-hand portion RP1, but not limited thereto. In some embodiments, Figure 7 The left portion LP1 and / or the right portion RP1 can be applied to the above. Figures 1 to 6 as well as Figures 8 to 12 In any of the embodiments.

[0059] Figure 8 The diagram shown is a top view of a portion of the display panel corresponding to the first display area according to some embodiments of the present invention. Figure 9 The image shows the display panel along... Figure 8 A schematic diagram of the cross-section line D-D'. (See diagram below.) Figure 8 and Figure 9 As shown, in some embodiments, the second electrodes 36 of different light-emitting units 16 may be selectively formed of different conductive layers CL3 and CL4. Specifically, the display panel 10 may include multiple conductive blocks 36a and multiple conductive blocks 36b, wherein the conductive blocks 36a are separated from each other and formed of conductive layer CL3, and the conductive blocks 36b are separated from each other and formed of conductive layer CL4. Figure 8In the embodiments, conductive blocks 36a and 36b can be arranged in an array, and conductive blocks 36a and 36b in the same row can be arranged alternately in the horizontal direction HD3, and conductive blocks 36a and 36b in the same column can be arranged alternately in the horizontal direction HD4. However, the arrangement of conductive blocks 36a and 36b in this invention is not limited to this. A conductive block 36b can be provided between two adjacent conductive blocks 36a, and the conductive block 36b can overlap with the adjacent conductive block 36a in the top view TD, so that two adjacent conductive blocks 36a and two adjacent conductive blocks 36b can surround and form an opening OP4. Therefore, conductive blocks 36a and 36b can form multiple openings OP4. In the top view TD, grid openings 18b and 44b can overlap with a corresponding opening OP4. The size of grid opening 18b and / or the size of grid opening 44b can, for example, be larger than the size of opening OP4. Figure 8 In some embodiments, conductive blocks 36a and 36b may be, for example, rhomboid or other suitable shapes.

[0060] exist Figure 9 In some embodiments, conductive block 36b may extend onto adjacent conductive block 36a to be electrically connected to adjacent conductive block 36a, but is not limited thereto. Conductive block 36a and adjacent conductive block 36b may have an overlapping portion in the top view TD, and the overlapping portion may overlap with grid frame 18a or grid frame 44a in the top view TD.

[0061] exist Figure 8 and Figure 9 In some embodiments, conductive block 36a may overlap with a pixel PX1 in the top view direction TD, and conductive block 36b may overlap with a pixel PX2 in the top view direction TD. That is, the second electrode 36 of the light-emitting unit 16 of pixel PX1 may be formed by conductive block 36a, and the second electrode 36 of the light-emitting unit 16 of pixel PX2 may be formed by conductive block 36b. The sizes of conductive blocks 36a and 36b of the present invention are not limited to those described above. In some embodiments, conductive block 36a and / or conductive block 36b may serve as the second electrode 36 of at least one light-emitting unit 16.

[0062] It should be noted that forming an opening by etching the second electrode 36 of the light-emitting unit 16 is not easy and can easily lead to uneven quality. In this embodiment, the conductive blocks 36a and 36b can be formed, for example, using a metal shield combined with a physical deposition process (e.g., vapor deposition), through the opening in the metal shield, by sequentially forming the conductive layers CL3 and CL4 on the light-emitting layer 34 and the insulating layer IN4. Therefore, by separately forming the staggered conductive blocks 36a and 36b to form the opening OP4, it is not necessary to etch the second electrode 36, thus improving the quality of the light-emitting unit 16 and the opening OP4.

[0063] In some embodiments, such as Figure 8 As shown, the size of the mesh opening 46b of the bridging unit 46 can be selectively larger than the size of the opening OP4 or the mesh opening 42b of the bridging unit 42, but is not limited thereto. In some embodiments, the size of the mesh opening 46b of the bridging unit 46 can also be smaller than the size of the opening OP4. Figure 8 The size of the grid opening 46b shown can be adapted to at least one grid opening 46b in other embodiments.

[0064] Figure 10 The diagram shown is a top view of different portions of the display panel corresponding to the first display area in some embodiments of the present invention. For example... Figure 10 As shown in the left portion LP2, in some embodiments, the strip grid 42a of the bridging unit 42 may include a strip portion SP and at least one grid frame 42a1, and the grid frame 42a1 may be electrically connected between the strip portion SP and the grid unit 18 to reduce the resistance value of the bridging unit 42. Each grid frame 42a1 may have an opening 42b1, and the opening 42b1 may not overlap with the light-emitting unit 16 in the top view TD. Figure 10 In embodiments, the strip-shaped portion SP may, for example, be with Figure 7 Left side LP1 or Figure 5 The same as the strip grid 42a. For example, the strip portion SP may include, for example, six grid frames 42a3, arranged in the extension direction (e.g., the horizontal direction HD3) of the strip grid 42a, and electrically connected between two adjacent grid cells 18. Figure 10 The strip grid 42a and Figure 7The difference in the strip-shaped grid 42a of the left-side portion LP1 is that the strip-shaped grid 42a may further include four grid frames 42a1, electrically connected to one side of the strip portion SP and the corresponding grid unit 18, but is not limited thereto. In some embodiments, the strip-shaped grid 42a may further include at least one grid frame 42a2, electrically connected to one side of the strip portion SP, and each grid frame 42a2 may have an opening 42b2, and the opening 42b2 may overlap with at least one light-emitting unit 16 in the top view TD. Figure 10 In some embodiments, the strip grid 42a may include four grid frames 42a2, each grid frame 42a2 may have an opening 42b2, and each opening 42b2 may overlap with a light-emitting unit 16 in the top view direction TD. In some embodiments, Figure 10 Grid frames 42a1 and / or 42a2 in the left part of LP2 can also be applied. Figure 10 The right-hand portion RP2 or other embodiments.

[0065] like Figure 10 As shown in the right-hand portion RP2, in some embodiments, the mesh opening 46b of the strip mesh 46a may overlap with a light-emitting unit 16 in the top-view direction TD. Figure 10 In some embodiments, the strip grid 46a may optionally include at least one grid frame P5, and the grid frame P5 may have an opening 46b1, which may not overlap with the light-emitting unit 16 in the top view TD, but is not limited thereto. Figure 10 The grid P5 in the right part of RP2 can also be applied. Figure 10 The left portion LP2 or other embodiments.

[0066] Figure 11 The diagram shown is a top view of portions of a display panel corresponding to a first display area and portions corresponding to a second display area, according to some embodiments of the present invention. To clearly show the grid units 18, 44, 22, 48, 42, 46, 50, and 52 of the display panel 10, Figure 11 The light-emitting unit and the light-emitting unit are omitted, but this is not a limitation. For example, Figure 11 As shown, the display panel 10 may include two bridging units 46 connected between two adjacent grid units 44. Figure 11 In some embodiments, bridging unit 46 may not overlap with bridging unit 42 in the top view direction TD, but may overlap with adjacent grid units 18, but is not limited to this. Since bridging unit 46 and grid units 18 may be made of different conductive layers (e.g., Figure 6 The conductive layers CL1 and CL2 shown are formed, and a dielectric layer (e.g., a dielectric layer) may be disposed between the bridging unit 46 and the grid unit 18. Figure 6The insulating layers shown (IN6) are thus electrically insulated from each other. In some embodiments, the bridging units 46 may be selectively symmetrical to each other with respect to the arrangement direction of the grid units 44 (e.g., the horizontal direction HD4), but are not limited thereto. In some embodiments, the bridging units 46 may overlap at least one grid opening 18b in the top view direction TD, for example, but are not limited thereto.

[0067] In addition, such as Figure 11 As shown, the display panel 10 may also include two bridging units 52 connected between two adjacent grid units 48. Figure 11 In some embodiments, bridging unit 52 may not overlap with bridging unit 50 in the top view direction TD, but may overlap with adjacent grid units 22, but is not limited thereto. Furthermore, bridging unit 52 and grid units 22 may be made of different conductive layers (e.g., Figure 6 The conductive layers CL1 and CL2 shown are formed and are connected through a dielectric layer (e.g., Figure 6 The insulating layer shown (IN6) is electrically insulating.

[0068] Figure 12 The diagram shown is a top view of mesh cells and bridging cells according to some embodiments of the present invention. Figure 12 As shown, in some embodiments, the bridging unit 46 may be asymmetrical with respect to the arrangement direction of the grid units 44 (e.g., the horizontal direction HD4).

[0069] Figure 13 The diagram shown is a top view of portions of the display panel corresponding to the first display area and portions corresponding to the second display area, according to some embodiments of the present invention. Figure 13 As shown, the display panel 10 may include multiple transparent sensing electrodes 54, multiple bridging wires 56, multiple transparent sensing electrodes 58, and multiple bridging wires 60, disposed on the first display area DR1 of the substrate 14. The transparent sensing electrodes 54 and bridging wires 56 can be connected to form multiple electrode strings ES1, and the transparent sensing electrodes 58 and bridging wires 60 can be connected to form multiple electrode strings ES2. In the top view TD, electrode strings ES1 may overlap electrode strings ES2. It should be noted that the transparent sensing electrodes 54 may have multiple openings OP5, and the transparent sensing electrodes 58 may have multiple openings OP6. Figure 13 In the middle, the opening OP5 can be similar to or the same as Figure 5 The grid opening 18b overlaps with or does not overlap with the light-emitting unit (such as) in the top-view direction TD, where it is located. Figure 5 The light-emitting units 16) overlap, and the opening OP6 may be similar to or the same as the light-emitting units 16) overlap. Figure 5 The grid opening 44b overlaps with or does not overlap with the light-emitting unit in the top view TD. To clearly display the electrode strings ES1, ES2, ES3, and ES4 of the display panel 10... Figure 13 The light-emitting unit and the light-emitting unit are omitted, but this is not a limitation.

[0070] like Figure 13 As shown, the display panel 10 may further include a plurality of transparent sensing electrodes 62, a plurality of bridging wires 64, a plurality of transparent sensing electrodes 66, and a plurality of bridging wires 68, disposed on the second display area DR2 of the substrate 14. The transparent sensing electrodes 62 and bridging wires 64 can be connected to form a plurality of electrode strings ES3, and the transparent sensing electrodes 66 and bridging wires 68 can be connected to form a plurality of electrode strings ES4. In the top view TD, electrode strings ES3 and ES4 may overlap. In some embodiments, when electrode strings ES3 and their corresponding electrode strings ES1 are arranged along the same line, electrode strings ES3 and ES1 can be electrically connected to each other. Similarly, when electrode strings ES4 and their corresponding electrode strings ES2 are arranged along the same line, electrode strings ES4 and ES2 can be electrically connected to each other.

[0071] In some embodiments, the transparent sensing electrode 54 and the bridging line 56 may be formed from the same transparent conductive layer, while the transparent sensing electrode 58 and the bridging line 60 may be formed from another transparent conductive layer, and a dielectric layer (e.g., a dielectric layer) may be disposed between the two transparent conductive layers. Figure 6 The insulating layer shown is IN6, but not limited thereto. In some embodiments, one of the transparent sensing electrodes 54, 58, 56, and 60 may be formed from the same transparent conductive layer, while the other of 56 and 60 may be formed from another transparent conductive layer. Similarly, in some embodiments, the transparent sensing electrodes 62, 64, 66, and 68 may be formed in a similar manner to the transparent sensing electrodes 54, 58, 56, and 60, and therefore will not be described in detail. The transparent conductive layer may, for example, include indium tin oxide, indium zinc oxide, or other suitable transparent conductive materials.
