[0057] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0058] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0059] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0060] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0061] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0062] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0063] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate.

[0064] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0065] With the development of display technology, display devices with touch display panels have brought a better user experience due to their simple and convenient operation.

[0066] For example, the touch display panel 100 may be an organic light-emitting diode (OLED) touch display panel, a quantum dot light-emitting diode (QLED) touch display panel, or a mini light-emitting diode (MLED) touch display panel, etc.; the embodiments of this application are illustrated with an OLED touch display panel 100, but the embodiments of this application are not limited thereto.

[0067] OLEDs are current-driven organic light-emitting devices that emit light through the injection and recombination of charge carriers. The luminous intensity is directly proportional to the injected current. Under the influence of an electric field, holes generated at the anode and electrons at the cathode move and are injected into the hole transport layer and electron transport layer, respectively, migrating to the emissive layer. When these two electrons meet in the emissive layer, they generate excitons, which excite the light-emitting molecules to produce visible light. Depending on their formulation, these molecules produce the three primary colors of red, green, and blue (RGB), constituting the basic colors. OLED touch display panels offer advantages such as high brightness, high efficiency, wide viewing angle, self-emissive design, all-solid-state operation, ultra-thin and ultra-lightweight construction, simple manufacturing process, fast response speed, full-color display capability, and good machinability. Therefore, they are increasingly widely used in various display devices such as mobile phones, tablets, computers, and televisions.

[0068] For example, as shown in FIG1, the touch display panel 100 includes a display area AA and a border area BB. The display area AA is used to display images. The display area AA of the touch display panel 100 includes a main display area AA1, an opening area HH and an optical sensing area CC. The main display area AA1 surrounds the optical sensing area CC and also surrounds the opening area HH. The opening area HH is used to place functional devices, such as cameras. The position corresponding to the optical sensing area CC (Sensor area) is used to place optical sensors. It can be understood that both the main display area AA1 and the optical sensing area CC can display images.

[0069] For example, as shown in FIG2, a plurality of sub-pixels P are disposed within the main display area AA1 and the optical sensing area CC of the touch display panel 100. The plurality of sub-pixels P are arranged in an array within the main display area AA1 and the optical sensing area CC, for example, in a rectangular array.

[0070] Each sub-pixel P can display a single color. For example, multiple sub-pixels P, including a first-color sub-pixel P1, a second-color sub-pixel P2, and a third-color sub-pixel P3, can display red, green, or blue respectively. By adjusting the brightness (grayscale) of different color sub-pixels P, and through color combination and superposition, multiple colors can be displayed, thereby achieving full-color display of the touch display panel 100.

[0071] It should be noted that the multiple sub-pixels P described in this application can also display other colors, such as white, yellow, pink, etc., and are not limited to the red, green or blue described above.

[0072] For example, as shown in FIG3, the touch display panel 100 includes a display substrate 10 and a touch sensor panel 20 (TSP). The display substrate 10 is used to display images, and the touch sensor panel 20 is used to touch and control the display substrate 10. The touch sensor panel 20 is disposed on the light-emitting side of the display substrate 10 to facilitate touch operation.

[0073] For example, as shown in FIG2, the display substrate 10 of the touch display panel 100 includes a plurality of sub-pixels P, which are the smallest units for displaying images on the display substrate 10. Each sub-pixel P includes a light-emitting device E and a pixel driving circuit D that controls the light-emitting device E to emit light. That is, one sub-pixel P corresponds to one light-emitting device E and one pixel driving circuit D. The plurality of sub-pixels P are arranged in the main display area AA1 and the optical sensing area CC according to a specified rule. For example, the plurality of sub-pixels P are arranged in multiple rows and columns. Since each sub-pixel P corresponds to one pixel driving circuit D, the pixel driving circuits D are also arranged in multiple rows and columns.

[0074] For example, the light-emitting device E can emit light, such as red, green, blue, or white light. By emitting light through multiple light-emitting devices E disposed in the main display area AA1 and the optical sensing area CC, the portion of the display substrate 10 located in the main display area AA1 and the optical sensing area CC can display an image. The light-emitting device E includes, but is not limited to, one of OLED, QLED, Mini LED, Micro LED, LED, etc.

[0075] For example, the pixel driving circuit D can be configured to provide an electrical signal (e.g., driving voltage or driving current) to a light-emitting device E coupled to the pixel driving circuit D in response to received scan signals and data signals (e.g., scan signals output from the scan driving circuit and data signals output from the data driving circuit), so as to drive the light-emitting device E to emit light, thereby enabling the display substrate 10 to display an image. The pixel driving circuit D may include a plurality of transistors and at least one (e.g., one; or multiple) capacitor. For example, the pixel driving circuit D may be a structure such as "2T1C", "6T1C", "7T1C", "6T2C" or "7T2C". Here, "T" represents a transistor, such as a thin-film transistor. The number preceding "T" indicates the number of transistors. "C" represents a capacitor, and the number preceding "C" indicates the number of capacitors.

[0076] For example, in each sub-pixel P, the light-emitting device E is electrically connected to the corresponding pixel driving circuit D. Specifically, the anode of the light-emitting device E is electrically connected to the corresponding pixel driving circuit D. In this way, the anode voltage input to the display substrate 10 is transmitted to the anode of the light-emitting device E through the pixel driving circuit D. At the same time, the cathode voltage is transmitted to the cathode of the light-emitting device E, thereby forming an electric field between the anode and the cathode, driving the light-emitting device E to emit light.

[0077] For example, as shown in FIG3, the display substrate 10 of the touch display panel 100 includes an array substrate 11, a light-emitting device layer 12 and an encapsulation layer 13 stacked in sequence, wherein the array substrate 11 includes a substrate 111 and a driving circuit layer 112.

[0078] Exemplarily, the substrate 111 supports other structures in the display substrate 10. The substrate 111 can be a flexible substrate, made of materials such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), ultrathin glass, or polyimide (PI). The substrate 111 can also be a rigid substrate, made of materials such as glass or PMMA (polymethyl methacrylate).

[0079] For example, the driving circuit layer 112 is configured to form a plurality of pixel driving circuits D and a plurality of signal lines for driving the pixel circuits. As shown in FIG3, the driving circuit layer 112 may include a plurality of conductive layers, which may include, for example, a semiconductor layer 1121, a gate conductive layer 1123, a first source-drain conductive layer 1125, and a second source-drain conductive layer 1128 sequentially disposed along a direction perpendicular to and away from the substrate 111. Of course, the driving circuit layer 112 may also include other conductive layers, such as a third source-drain conductive layer, which is not specifically limited here.

[0080] For example, as shown in FIG3, the plurality of conductive layers form a plurality of transistors. The transistors may include a semiconductor pattern T11 located on the semiconductor layer 1121, a gate T12 located on the gate conductive layer 1123, and a source T13 and a drain T14 located on the first source-drain conductive layer 1125.

[0081] For example, the driving circuit layer 112 may further include an insulating layer located between adjacent conductive layers, the insulating layer being used to isolate adjacent conductive layers. For instance, as shown in FIG3, the driving circuit layer 112 may include a gate insulating layer 1122 located between the semiconductor layer 1121 and the gate conductive layer 1123, an interlayer dielectric layer 1124 located between the gate conductive layer 1123 and the first source / drain conductive layer 1125, a passivation layer 1126 and a first planarization layer 1127 located between the first source / drain conductive layer 1125 and the second source / drain conductive layer 1128, and a second planarization layer 1129 located between the second source / drain conductive layer 1128 and the light-emitting device layer 12. Of course, the driving circuit layer 112 may also include other insulating film layers, which will not be described in detail here.

[0082] For example, the light-emitting device layer 12 is configured to form a plurality of light-emitting devices E, as shown in FIG3. The light-emitting device layer 12 includes a first electrode layer 121, a pixel defining layer 122, a light-emitting layer 123, and a second electrode layer 124 stacked along a direction away from the substrate 111. The second electrodes of the plurality of light-emitting devices E are interconnected to form a continuous whole-layer structure. The pixel defining layer 122 includes a plurality of openings. The first electrode layer 121 includes a plurality of first electrodes. The light-emitting layer 123 includes a plurality of light-emitting portions 123-1. A light-emitting device E includes an opening of the pixel defining layer 122, a first electrode, a light-emitting portion 123-1, and a second electrode. At least a portion of a first electrode and at least a portion of a light-emitting portion 123-1 are located within an opening. One of the light-emitting devices E is connected to a pixel driving circuit D.

[0083] For example, the first electrode layer 121 may be formed of a transparent conductive material with a high work function, and the electrode material may include indium tin oxide (ITO), indium zinc oxide (IZO), indium gallium oxide (IGO), zinc gallium oxide (GZO), zinc oxide (ZnO), indium oxide (In2O3), zinc aluminum oxide (AZO), and carbon nanotubes, etc. The first electrode layer 121 may include only one transparent conductive material layer, or it may include multiple transparent conductive material layers. For example, each first electrode includes three conductive material layers, namely indium tin oxide, silver, and indium tin oxide. The second electrode layer 124 may be formed of a material with high conductivity and low work function, and the electrode material may include alloys such as magnesium aluminum alloy (MgAl) and lithium aluminum alloy (LiAl), or elemental metals such as magnesium (Mg), aluminum (Al), lithium (Li), and silver.

[0084] For example, the material of the light-emitting layer 123 may include low molecular weight organic materials or polymer materials, which are fluorescent or phosphorescent materials that can emit red, green, blue, or white light under the action of an electric field. In order to improve the luminous efficiency of the light-emitting device E in the display substrate 10, the light-emitting device layer 12 may also include one or more of the following: an electron transport layer (ETL), an electron injection layer (EIL), a hole transport layer (HTL), and a hole injection layer (HIL).

[0085] For example, as shown in FIG3, the encapsulation layer 13 is located on the side of the light-emitting device layer 12 away from the substrate 111. The encapsulation layer 13 may include a first inorganic encapsulation layer 131, an organic encapsulation layer 132, and a second inorganic encapsulation layer 133. The first inorganic encapsulation layer 131 and the second inorganic encapsulation layer 133 can be formed by plasma chemical vapor deposition, and the organic encapsulation layer 132 can be formed by inkjet printing. The encapsulation layer 13 is used to encapsulate the light-emitting device layer 12, preventing water and oxygen in the environment from penetrating the light-emitting device layer 12, thus protecting the light-emitting device layer 12 and preventing external water and oxygen from corroding the display substrate 10.

[0086] For example, the touch substrate 20 of the touch display panel 100 can be formed by a flexible multi-layer on cell (FMLOC) process, and the touch substrate 20 typically includes multiple film layers.

[0087] For example, as shown in FIG4, the touch substrate 20 of the touch display panel 100 may include a plurality of first touch units 21 and a plurality of second touch units 22. The first touch units 21 extend along a first direction X, and the second touch units 22 extend along a second direction Y. The first touch units 21 and the second touch units 22 are insulated from each other, and the first direction X and the second direction Y intersect, for example, the first direction X and the second direction Y are perpendicular.

[0088] For example, as shown in FIG4 and referring to FIG5, the first touch unit 21 may include a plurality of first touch electrodes 211 and a plurality of first connection portions 212, each first connection portion 212 being electrically connected to two adjacent first touch electrodes 211. The second touch unit 22 includes a plurality of second touch electrodes 221 and a plurality of second connection portions 222, each second connection portion 222 being electrically connected to two adjacent second touch electrodes 221, and the first connection portions 212 and the second connection portions 222 being mutually insulated. Mutual capacitance can be generated between adjacent first touch electrodes 211 and second touch electrodes 221. After the touch display panel 100 is touched, the mutual capacitance value between adjacent first touch electrodes 211 and second touch electrodes 221 will change, thereby the touch position can be determined by detecting the change in mutual capacitance value.

[0089] For example, as shown in Figures 6 and 7, the touch substrate 20 of the touch display panel 100 may include a touch substrate 23, a touch metal layer 24, and an insulating protective layer 25 stacked sequentially. The touch metal layer 24 may include a first touch metal layer 241 and a second touch metal layer 243, with a first insulating layer 242 disposed between the first touch metal layer 241 and the second touch metal layer 243.

[0090] For example, the first touch electrode 211, the second touch electrode 221, and the first connecting portion 212 may be disposed on the first touch metal layer 241, and the second connecting portion 222 may be disposed on the second touch metal layer 243; or, the second connecting portion 222 may be disposed on the first touch metal layer 241, and the first touch electrode 211, the second touch electrode 221, and the first connecting portion 212 may be disposed on the second touch metal layer 243; or, the first touch electrode 211 and the first connecting portion 212 may be disposed on the first touch metal layer 241, and the second touch electrode 221 and the second connecting portion 222 may be disposed on the second touch metal layer 243; or, the second touch electrode 221 and the second connecting portion 222 may be disposed on the first touch metal layer 241, and the first touch electrode 211 and the first connecting portion 212 may be disposed on the second touch metal layer 243. This disclosure does not impose any limitations. This application describes a first touch electrode 211, a second touch electrode 221, and a first connection portion 212 disposed on a first touch metal layer 241, and a second connection portion 222 disposed on a second touch metal layer 243.

[0091] It should be noted that, using FMLOC technology, multiple first touch units 21 and multiple second touch units 22 of the touch substrate 20 are directly disposed on the encapsulation layer 13 of the display substrate 10. In this case, the touch substrate 23 of the touch substrate 20 is the encapsulation layer 13 of the display substrate 10.

[0092] For example, as shown in Figures 8A and 8B, and referring to Figure 4, the first touch electrode 211 or the second touch electrode 221 of the touch substrate 20 in the touch display panel 100 may include a plurality of connected touch metal lines 24-1. The plurality of touch metal lines 24-1 in the first touch electrode 211 are connected as a whole, and the plurality of touch metal lines 24-1 in the second touch electrode 221 are connected as a whole. The plurality of touch metal lines 24-1 in the first touch electrode 211 and the plurality of touch metal lines 24-1 in the second touch electrode 221 are not connected, so that the first touch electrode 211 and the second touch electrode 221 are insulated from each other.

[0093] For example, as shown in Figures 8A and 8B, and referring to Figure 3, the orthogonal projections of the plurality of touch metal lines 24-1 in the first touch electrode 211 or the second touch electrode 221 onto the light-emitting layer 123 are located between the light-emitting portions 123-1 of two adjacent sub-pixels P, and are interconnected. It can be understood that the plurality of touch metal lines 24-1, for example, four touch metal lines 24-1, surround the light-emitting portion 123-1 of one sub-pixel P; since the plurality of sub-pixels P are closely arranged, one touch metal line 24-1 belongs to both the touch metal lines 24-1 surrounding the light-emitting portion 123-1 of one sub-pixel P and the touch metal lines 24-1 surrounding the light-emitting portion 123-1 of the sub-pixel P adjacent to that sub-pixel P.

[0094] In some embodiments, as shown in Figures 8A and 8B, the widths of the multiple touch metal lines 24-1 are all equal, for example, the width can be a, and the distances from the multiple touch metal lines 24-1 to the light-emitting portion 123-1 of their adjacent sub-pixels P are all the same, for example, the distance can be x.

[0095] For example, as shown in FIG9, the display device 1000 includes a back film 200, a touch display panel 100, and a cover plate 300 stacked sequentially. It also includes an optical sensor 400 disposed on the side of the back film 200 away from the cover plate 300. The optical sensor 400 corresponds to the optical sensing area CC of the touch display panel 100 and is used to sense ambient light. The back film 200 mainly serves to support, buffer, reinforce, and dissipate heat. It provides support for the touch display panel 100, allows heat generated by the touch display panel 100 to be quickly dissipated through the back film 200, and protects the touch display panel 100. To ensure that ambient light can enter the optical sensor 400 without obstruction, the portion of the back film 200 corresponding to the optical sensing area CC of the touch display panel 100 can be removed to prevent the back film 200 from blocking light, thus allowing ambient light to enter the optical sensor 400. Ambient light passes through cover plate 300 and touch display panel 100 before entering optical sensor 400. Optical sensor 400 identifies ambient light and automatically adjusts the brightness of touch display panel 100.

[0096] The PPI (Pixels per inch) of a touch display panel 100 indicates the number of pixels per inch. A higher PPI value means the touch display panel 100 displays images at a higher density, resulting in more realistic and detailed images. Currently, high PPI has become an important development direction for touch display panels 100, such as OLED touch display panels 100. Due to their superior display effect and higher image clarity, high PPI touch display panels 100 are increasingly widely used in the display field, for example, in VR (Virtual Reality) or AR (Augmented Reality) display products.

[0097] Users have increasingly higher demands for display product resolution. To increase the resolution of display products, it is necessary to increase the density of subpixels P in the touch display panel 100, that is, to increase the number of subpixels P that can be accommodated per unit area of ​​the touch display panel 100. The more subpixels P set in the touch display panel 100, the higher the PPI of the touch display panel 100, and the denser the arrangement of multiple subpixels P. To maximize the density of subpixels P in the touch display panel 100, the distance between two adjacent subpixels P can be reduced.

[0098] For example, in a plurality of sub-pixels P of the touch display panel 100, as shown in FIG10, a sub-pixel P includes a light-emitting part 123-1. For example, the light-emitting part 123-1 of some sub-pixels P can emit red light, for example, the light-emitting part 123-1 of another sub-pixel P can emit green light, and for example, the light-emitting part 123-1 of a third sub-pixel P can emit blue light. The maximum emission angle of the different colors of light emitted by the light-emitting part 123-1 is different. For example, the maximum emission angle of the emitted green light is larger, so the green light is more diffuse, and the maximum emission angle of the emitted red light is smaller, so the red light is more focused.

[0099] It should be noted that the multiple sub-pixels P described in this application can also display other colors, such as white, and are not limited to the red, green, or blue described above. This application uses the display of multiple sub-pixels P as an example for illustration.

[0100] It should be noted that the maximum emission angle refers to the following: as shown in Figure 10, the light emitted from a certain point on the light-emitting part 123-1 is emitted outward in a fan shape. A normal line perpendicular to the plane where the light-emitting part 123-1 is located is drawn at that point. The angle between the light ray emitted from that point that is furthest from the normal line and the normal line is the maximum emission angle.

[0101] As the number of sub-pixels P that can be accommodated within a unit area of ​​100 in a touch display panel continues to increase, the optical sensor 400 will experience a decrease in its ability to sense ambient light, causing the display product to be unable to automatically and quickly adjust the screen brightness, thus affecting the quality of the display product.

[0102] Analysis revealed that, as shown in Figure 10, the maximum emission angle of green light is b1, that of blue light is b2, and that of red light is b3, with b1 > b2 > b3. According to Figures 8A and 8B, the width 'a' of the multiple touch metal lines 24-1 is equal, and the distance 'x' from each touch metal line 24-1 to the light-emitting part 123-1 of its adjacent sub-pixel P is also the same. Therefore, the light emitted by the light-emitting part 123-1 of the sub-pixel P in the touch display panel 100 has a larger maximum emission angle and is more diffuse, such as green light, after passing through certain areas inside the touch display panel 100. When an opaque film layer, such as multiple touch metal lines 24-1 of the touch metal layer 24, is used, since the touch metal layer 24 is disposed between the light-emitting parts 123-1 of adjacent sub-pixels P, and the distance between the light-emitting parts 123-1 of two adjacent sub-pixels P is small, and the green light is relatively diffuse, some green light will illuminate the touch metal lines 24-1 of the touch metal layer 24 and be reflected. The reflected light will enter the optical sensor 400, interfering with the optical sensor 400's perception of ambient light, reducing the optical sensor 400's sensing ability, and making the display product unable to automatically and quickly adjust the screen brightness.

[0103] Understandably, some red and blue light rays, like green light rays, will also illuminate the touch metal lines 24-1 of the touch metal layer 24 and be reflected. The reflected light will enter the optical sensor 400, reducing the sensing capability of the optical sensor 400. However, red and blue light rays are more concentrated than green light rays, so relatively less light rays are emitted onto the touch metal lines 24-1 of the touch metal layer 24. Therefore, less blue or red light rays enter the optical sensor 400 after reflection, and the impact on the quality of the display product is relatively small.

[0104] Based on this, as shown in Figures 11A, 11B, 12A, 12B, 13A, 13B, 14A, 14B, 16A, 16B, 17A, 17B, 18A, 18B, 19A, 19B, 20A, 20B, 21A, 21B, 22A, and 22B, and referring to Figures 1, 3, 6, and 7, this application provides a touch display panel 100. The touch display panel 100 includes a display area AA, which includes a main display area AA1 and an optical sensing area CC. The main display area AA1 surrounds the optical sensing area CC. The touch display panel 100 also includes a substrate 111, a light-emitting layer 123, and a touch metal. Layer 24, light-emitting layer 123 is disposed on one side of substrate 111, light-emitting layer 123 includes multiple light-emitting parts 123-1, multiple light-emitting parts 123-1 include multiple selected color light-emitting parts 1; touch metal layer 24 is disposed on the side of light-emitting layer 123 away from substrate 111, touch metal layer 24 includes multiple connected touch metal lines 24-1, the orthographic projection of touch metal lines 24-1 on light-emitting layer 123 is located between adjacent light-emitting parts 123-1; in the plane where substrate 111 is located, the total area of ​​multiple touch metal lines 24-1 around the selected color light-emitting part 1 of optical sensing area CC is smaller than the total area of ​​multiple touch metal lines 24-1 around the selected color light-emitting part 1 of main display area AA1.

[0105] It should be noted that, as shown in Figures 11A to 22B, the following descriptions of the positional relationship and dimensions between the light-emitting part 123-1 and the touch metal line 24-1 are based on the premise that the light-emitting part 123-1 and the touch metal line 24-1 are on the same reference plane, for example, by projecting both the light-emitting part 123-1 and the touch metal line 24-1 onto the plane where the substrate 111 is located. For example, multiple touch metal lines 24-1 around the selected color light-emitting part 1 means that, among the orthographic projections of multiple light-emitting parts 123-1 on the substrate 111 and multiple orthographic projections of multiple touch metal lines 24-1 on the substrate 111, there are multiple orthographic projections of touch metal lines 24-1 around the orthographic projection of the selected color light-emitting part 1.

[0106] For example, both the main display area AA1 and the optical sensing area CC are provided with sub-pixels P, and both can display images.

[0107] For example, as shown in FIG11A, multiple sub-pixels P may include sub-pixels P of various colors, such as a first-color sub-pixel P1, a second-color sub-pixel P2, and a third-color sub-pixel P3. The first-color sub-pixel P1 may be a green sub-pixel, the second-color sub-pixel P2 may be a blue sub-pixel, and the third-color sub-pixel P3 may be a red sub-pixel. Each sub-pixel P includes a light-emitting part 123-1, that is, the first-color sub-pixel P1 includes a first-color light-emitting part G, for example, emitting green light; the second-color sub-pixel P2 includes a second-color light-emitting part B, for example, emitting blue light; and the third-color sub-pixel P3 includes a third-color light-emitting part R, for example, emitting red light.

[0108] For example, the plurality of light-emitting parts 123-1 may include a plurality of selected color light-emitting parts 1. The maximum emission angle of the light emitted by the selected color light-emitting parts 1 is relatively large, and the emitted light is relatively divergent. The selected color light-emitting parts 1 can be any one of a first color sub-pixel P1, a second color sub-pixel P2, and a third color sub-pixel P3. The plurality of selected color light-emitting parts 1 refers to all the light-emitting parts 123-1 emitting the selected color among the plurality of sub-pixels P of the touch display panel 100. For example, the plurality of selected color light-emitting parts 1 can be a plurality of first color light-emitting parts G, that is, all the light-emitting parts 123-1 emitting the first color light, such as green light; or the plurality of selected color light-emitting parts 1 can be a plurality of second color light-emitting parts B, that is, all the light-emitting parts 123-1 emitting the second color light, such as blue light; or the plurality of selected color light-emitting parts 1 can be a plurality of third color light-emitting parts R, that is, all the light-emitting parts 123-1 emitting the third color light, such as red light.

[0109] It should be noted that the multiple sub-pixels in this application may also include fourth-color sub-pixels, etc., and the fourth-color sub-pixels may be, for example, white sub-pixels; this disclosure does not limit this. When the multiple sub-pixels include fourth-color sub-pixels, etc., the multiple selected-color light-emitting parts may also be multiple fourth-color light-emitting parts, that is, all light-emitting parts that emit fourth-color light, such as white light. This disclosure does not limit this.

[0110] In some embodiments, only the film layer of the optical sensing area CC of the touch display panel 100 is changed, and the film layer of the main display area AA1 is not changed. Therefore, in the plane where the touch display panel 100 is located, as shown in Figures 8A and 8B, the width of the multiple touch metal lines 24-1 is equal, for example, the width can be a, and the distance from the multiple touch metal lines 24-1 to the light-emitting part 123-1 of the adjacent sub-pixel P is the same, for example, the distance can be x.

[0111] In some embodiments, as shown in FIG11A, the selected color light-emitting part 1 can be, for example, a first color light-emitting part G, which emits green light; the light-emitting part 123-1 that emits other colors of light besides the selected color light-emitting part 1 can be a second color light-emitting part B, which emits blue light, and a third color light-emitting part R, which emits red light.

[0112] For example, in addition to the light-emitting portion 123-1 located at the edge of the display area AA, each selected color light-emitting portion 1 is surrounded by multiple touch metal lines 24-1, for example, four touch metal lines 24-1. The total area of ​​the multiple touch metal lines 24-1 surrounding at least one selected color light-emitting portion 1 of the optical sensing area CC, for example, four touch metal lines 24-1, can be set to be smaller than the total area of ​​the multiple touch metal lines 24-1 surrounding the selected color light-emitting portion 1 of the main display area AA1. The area of ​​the touch metal line 24-1 is the product of the length and width of the touch metal line 24-1.

[0113] By setting the total area of ​​multiple touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC, for example, the total area of ​​four touch metal lines 24-1, to be smaller than the total area of ​​multiple touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1, the occupied area of ​​the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is effectively reduced. This reduces the amount of light emitted by the selected color light-emitting part 1 that shines on the touch metal lines 24-1, thereby reducing the amount of light reflected from the touch metal lines 24-1 into the optical sensor 400. This reduces the interference caused by the light emitted by the selected color light-emitting part 1 being reflected from the touch metal lines 24-1 into the optical sensor 400, effectively improving the sensing capability of the optical sensor 400. This allows the display product to automatically and quickly adjust the screen brightness, ensuring the reliability of the display product.

[0114] In some embodiments, as shown in Figures 11A, 11B, 12A, 12B, 13A, and 13B, and referring to Figures 8A and 8B, the width of at least a portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC is smaller than the width of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1.

[0115] "At least a portion of the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC" can be understood as: the width of all touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is smaller than the width of touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1; "At least a portion of the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC" can also be understood as: the width of a portion of the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is smaller than the width of touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width of another portion of the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is greater than or equal to the width of touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1. These two cases will be described in detail below.

[0116] In some embodiments, the relevant film layers of the optical sensing area CC of the touch display panel 100 are shown in Figures 11A, 11B, 12A, and 12B, and with reference to Figures 8A and 8B, the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC is smaller than the width a of the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1.

[0117] For example, the wider the touch metal line 24-1, the larger the reflective surface of the touch metal line 24-1 relative to the light emitted by the light-emitting part 123-1. This results in more light being reflected by the touch metal line 24-1, leading to more interference signals received by the optical sensor 400 in the optical sensing area CC, thus reducing the sensing capability of the optical sensor 400. Simultaneously, when ambient light enters the touch display panel 100, the wider touch metal line 24-1 blocks more of the ambient light, reducing the light transmittance of the touch display panel 100 and allowing less ambient light to pass through. When ambient light enters the optical sensor 400, it prevents the optical sensor 400 from quickly and accurately sensing the ambient light, thus affecting the sensing capability of the optical sensor 400. Therefore, the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC can be set to be smaller than the width a of the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1. This reduces the light reflected by the touch metal lines 24-1 and also reduces the obstruction of ambient light by the touch metal lines 24-1, significantly improving the sensing capability of the optical sensor 400. The width c1 of the touch metal lines 24-1 is determined by the manufacturing process.

[0118] For example, as shown in Figures 8A and 8B, the width of all touch metal lines 24-1 in the main display area AA1 is equal, for example, it can be a. That is, the width of the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1 is a. As shown in Figures 11A, 11B, 12A, and 12B, the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC is less than a.

[0119] It should be noted that the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC can be the same as shown in Figures 12A and 12B, or they can be different as shown in Figures 11A and 11B, as long as the width c1 of the four touch metal lines 24-1 is less than a. This disclosure does not limit this.

[0120] For example, the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC is smaller than the width a of the touch metal lines 24-1 of the main display area AA1. This effectively reduces the area occupied by the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC, thereby reducing the amount of light emitted by the selected color light-emitting part 1 that shines on the touch metal lines 24-1. This further reduces the amount of light reflected from the touch metal lines 24-1 into the optical sensor 400, reducing the interference caused by the light emitted by the selected color light-emitting part 1 being reflected from the touch metal lines 24-1 into the optical sensor 400. This effectively improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness and ensuring the reliability of the display product.

[0121] In some embodiments, the relevant film layers of the optical sensing area CC of the touch display panel 100 are shown in Figures 11A, 11B, 12A, and 12B, and with reference to Figures 8A and 8B, the width c2 of the four touch metal lines 24-1 around at least one other color light-emitting part 2 of the optical sensing area CC is also smaller than the width a of the touch metal lines 24-1 around the other color light-emitting part 2 of the main display area AA1.

[0122] It should be noted that the width c2 of the four touch metal lines 24-1 around at least one other color light-emitting part 2 of the optical sensing area CC can be the same as shown in FIG12B, or different as shown in FIG11B, as long as the width c2 of the four touch metal lines 24-1 is less than a. This disclosure does not limit it here.

[0123] In some embodiments, the relevant film layers of the optical sensing area CC of the touch display panel 100 are shown in Figures 11A and 12A, and with reference to Figure 8A, due to the layout of the sub-pixels P, there are many selected color light-emitting parts 1, and all the touch metal lines 24-1 are distributed around multiple selected color light-emitting parts 1. That is, the four touch metal lines 24-1 around each selected color light-emitting part 1 are also one of the touch metal lines 24-1 around the four other color light-emitting parts 2 adjacent to the selected color light-emitting part 1. Therefore, in this embodiment, the four touch metal lines 24-1 around the other color light-emitting parts 2 are also the touch metal lines 24-1 around the selected color light-emitting part 1.

[0124] In some embodiments, as shown in Figures 12A and 12B, in the optical sensing area CC, the width c1 of the touch metal line 24-1 around the selected color light-emitting part 1 is equal to the width c2 of the touch metal line 24-1 around the other color light-emitting parts 2, and both are smaller than the width a of the touch metal line 24-1 of the main display area AA1.

[0125] For example, the width c1 of the four touch metal lines 24-1 around at least one selected color light-emitting part 1 of the optical sensing area CC and the width c2 of the four touch metal lines 24-1 around at least one other color light-emitting part 2 are both smaller than the width a of the touch metal lines 24-1 of the main display area AA1. This significantly reduces the area occupied by the touch metal lines 24-1 of the optical sensing area CC, thereby reducing the amount of light emitted by the light-emitting part 123-1 that illuminates the touch metal lines 24-1. Consequently, the amount of light reflected from the touch metal lines 24-1 into the optical sensor 400 is reduced, thus reducing the interference caused by the light emitted by the light-emitting part 123-1 being reflected from the touch metal lines 24-1 into the optical sensor 400. This further improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness and ensuring the reliability of the display product.

[0126] In some embodiments, as shown in Figures 13A and 13B, and referring to Figures 8A and 8B, the width d2 of the partial touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is smaller than the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width d1 of the partial touch metal line 24-1 around the selected color light-emitting part 1 is greater than or equal to the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1.

[0127] For example, as shown in FIG13A, among the four touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the optical sensing area CC, for example, the width d2 of two touch metal lines 24-1 is smaller than the width a of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1; the width d1 of the other two touch metal lines 24-1 is equal to the width a of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1. As shown in FIG13B, among the four touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the optical sensing area CC, for example, the width d2 of two touch metal lines 24-1 is smaller than the width a of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1; the width d1 of the other two touch metal lines 24-1 is greater than the width a of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1.

[0128] It should be noted that in this embodiment, among the four touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC, the width d2 of one touch metal line 24-1 is smaller than the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width d1 of the other three touch metal lines 24-1 is equal to the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1; alternatively, the width d2 of three touch metal lines 24-1 is smaller than the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width d1 of the remaining touch metal line 24-1 is equal to the width a of the selected color light-emitting part 1 of the main display area AA1. The width 'a' of the touch metal lines 24-1 surrounding the light-emitting part 1; alternatively, the width 'd2' of one touch metal line 24-1 can be less than the width 'a' of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1, and the width 'd1' of the remaining three touch metal lines 24-1 can be greater than the width 'a' of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1; alternatively, the width 'd2' of the three touch metal lines 24-1 can be less than the width 'a' of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1, and the width 'd1' of the remaining one touch metal line 24-1 can be greater than the width 'a' of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1. This disclosure is not limited, as long as the total area of ​​the multiple touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the optical sensing area CC is less than the total area of ​​the multiple touch metal lines 24-1 surrounding the selected color light-emitting part 1 of the main display area AA1.

[0129] Furthermore, the width distribution of the touch metal lines 24-1 around the multiple selected color light-emitting parts 1 of the optical sensing area CC can be the same or different, and this disclosure does not limit it.

[0130] For example, this embodiment reduces the area occupied by the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC, thereby reducing the amount of light emitted by the selected color light-emitting part 1 that shines on the touch metal line 24-1. This reduces the amount of light reflected from the touch metal line 24-1 into the optical sensor 400, thus reducing the interference caused by the light emitted by the selected color light-emitting part 1 being reflected from the touch metal line 24-1 into the optical sensor 400. This effectively improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness and ensuring the reliability of the display product.

[0131] In some embodiments, as shown in Figures 13A and 13B, and referring to Figures 8A and 8B, the width e1 of the partial touch metal line 24-1 around the partial other color light-emitting part 2 of the optical sensing area CC is greater than or equal to the width a of the touch metal line 24-1 around the partial other color light-emitting part 2 of the main display area AA1.

[0132] For example, as shown in Figures 13A and 13B, and referring to Figures 8A and 8B, multiple touch metal lines 24-1 are disposed between the light-emitting parts 123-1 of adjacent sub-pixels P and are interconnected. For instance, if a first color sub-pixel P1 and a second color sub-pixel P2 are adjacent, and the selected color light-emitting part 1 is the first color light-emitting part G of the first color sub-pixel P1, then the second color light-emitting part B of the second color sub-pixel P2 is another color light-emitting part 2. A touch metal line 24-1 is disposed between the first color light-emitting part G and the second color light-emitting part B. Therefore, the touch metal line 24-1 is both around the selected color light-emitting part 1 and around the other color light-emitting parts 2. The width d2 of the portion of touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is less than the width a of the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width d1 of the portion of touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1 is greater than or equal to the width a of the selected color light-emitting part 123-1 of the main display area AA1. The width a of the touch metal line 24-1 around part 1; can also be considered as the width e2 of at least one touch metal line 24-1 around a portion of the other color light-emitting parts 2 adjacent to the selected color light-emitting part 1, which is less than the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width e1 of at least one touch metal line 24-1 around the other color light-emitting parts 2 is greater than or equal to the width a of the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1.

[0133] The total area of ​​the multiple touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is smaller than the total area of ​​the multiple touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1. As a result, there is a certain difference between the capacitance and resistance of the touch substrate 20, which has a certain impact on the touch performance of the touch substrate 20. However, the impact is very small and sufficient to meet the touch performance requirements of conventional display products.

[0134] For display products with stringent touch performance requirements, to ensure that the touch performance of the touch substrate 20 is unaffected or only slightly affected, as shown in Figure 13B and referring to Figure 8B, the width e1 of the touch metal line 24-1 between two adjacent other color light-emitting parts 2 is greater than or equal to the width a of the touch metal line 24-1 around the other color light-emitting parts 2 in the main display area AA1. In other words, the area of ​​the touch metal line 24-1 between the two adjacent other color light-emitting parts 2 is increased. This arrangement can keep the overall area of ​​the touch metal line 24-1 in the optical sensing area CC on the touch substrate 20 constant or slightly change, reducing the changes in capacitance and resistance of the touch substrate 20, ensuring the touch uniformity of the touch substrate 20, and thus ensuring that the touch performance of the touch substrate 20 is unaffected. At the same time, the area occupied by the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is reduced, thereby reducing the amount of light emitted by the selected color light-emitting part 1 that shines on the touch metal line 24-1. This further reduces the amount of light reflected from the touch metal line 24-1 into the optical sensor 400, reducing interference caused by the light emitted by the selected color light-emitting part 1 being reflected from the touch metal line 24-1 into the optical sensor 400. This effectively improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness and ensuring the reliability of the display product.

[0135] In some embodiments, as shown in Figures 14A and 14B, and referring to Figures 8A and 8B, the number of breaks in the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is greater than the number of breaks in the touch metal line 24-1 around the selected color light-emitting part 1 of the main display area AA1.

[0136] For example, the break is to remove a portion of a touch metal line 24-1, dividing the touch metal line 24-1 into two smaller parts. Although a break is provided, it is necessary to ensure that the multiple touch metal lines 24-1 in the first touch electrode 211 or the second touch electrode 221 are interconnected. That is, the touch metal lines 24-1 in the first touch electrode 211 or the second touch electrode 221 are generally connected. Although the touch metal lines 24-1 are not connected at the break position, the two smaller parts of the touch metal line 24-1 are connected to other touch metal lines 24-1 respectively, which can also ensure that the touch metal lines 24-1 in the first touch electrode 211 or the second touch electrode 221 are generally connected.

[0137] It is understood that this application does not select all of the areas surrounding the selected color light-emitting part 1. For example, all four touch metal lines 24-1 are provided with breaks. While ensuring that the touch metal lines 24-1 are generally connected in the first touch electrode 211 or the second touch electrode 221, this application may provide breaks only on one, two, or three touch metal lines 24-1 around the selected color light-emitting part 1. Alternatively, breaks may be provided on one, two, or three touch metal lines 24-1 around a portion of the selected color light-emitting part 1, and breaks may be provided on all four touch metal lines 24-1 around the selected color light-emitting part 1 in another portion. The number of breaks in the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC can be adjusted according to the actual process. The greater the amount of light reflected by the touch metal line 24-1 from the light-emitting part 123-1, the more breaks in the touch metal line 24-1 around the light-emitting part 123-1. This application does not limit this.

[0138] For example, by setting breaks in the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC, the area occupied by the touch metal line 24-1 around the selected color light-emitting part 1 can be reduced. The more breaks there are, the greater the reduction in area, thereby reducing the amount of light emitted by the selected color light-emitting part 1 that shines on the touch metal line 24-1. This further reduces the amount of light reflected from the touch metal line 24-1 into the optical sensor 400, reducing the interference caused by the light emitted by the selected color light-emitting part 1 being reflected from the touch metal line 24-1 into the optical sensor 400. This effectively improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness, thus ensuring the reliability of the display product.

[0139] In some embodiments, as shown in Figures 14A and 14B, and referring to Figures 8A and 8B, the number of breaks in the touch metal lines 24-1 around the other color light-emitting parts 2 of the optical sensing area CC is greater than the number of breaks in the touch metal lines 24-1 around the other color light-emitting parts 2 of the main display area AA1.

[0140] In some embodiments, since the amount of light emitted by other color light-emitting parts 2 that illuminates the touch metal line 24-1 is less than the amount of light emitted by the selected color light-emitting part 1 that illuminates the touch metal line 24-1, as shown in FIG14A and FIG14B, and referring to FIG8A and FIG8B, the number of breaks in the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC can be greater than the number of breaks in the touch metal line 24-1 around the other color light-emitting parts 2.

[0141] For example, the touch metal line 24-1 around the other color light-emitting part 2 of the optical sensing area CC can also be provided with a break, just like the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is provided with a break, which will not be described again here.

[0142] This configuration reduces the area of ​​the touch metal line 24-1 around the selected color light-emitting part 1 of the optical sensing area CC and the area of ​​the touch metal line 24-1 around the other color light-emitting parts 2. This further reduces the amount of light emitted by the light-emitting part 123-1 of the optical sensing area CC that illuminates the touch metal line 24-1. Consequently, it reduces the amount of light reflected from the touch metal line 24-1 into the optical sensor 400, thereby reducing interference caused by the light emitted by the light-emitting part 123-1 being reflected into the optical sensor 400 through the touch metal line 24-1. This effectively improves the sensing capability of the optical sensor 400, enabling the display product to automatically and quickly adjust the screen brightness and ensuring the reliability of the display product.

[0143] In some embodiments, as shown in Figures 15A and 15B, and referring to Figures 8A and 8B, the distance from at least a portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC to the selected color light-emitting portion 1 is greater than the distance from the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1 to the selected color light-emitting portion 1.

[0144] In some embodiments, as shown in Figures 15A and 15B, and referring to Figures 8A and 8B, the distance from at least a portion of the touch metal lines 24-1 around the other color light-emitting portion 2 of the optical sensing area CC to the other color light-emitting portion 2 is less than the distance from the touch metal lines 24-1 around the other color light-emitting portion 2 of the main display area AA1 to the other color light-emitting portion 2.

[0145] For example, the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC are designed to be non-equidistant, as are the touch metal lines 24-1 around the other color light-emitting parts 2.

[0146] Increasing the distance from the touch metal line 24-1 to the selected color light-emitting unit 1 and decreasing the distance from the touch metal line 24-1 to other color light-emitting units 2 reduces the amount of light reflected by the touch metal line 24-1 from the selected color light-emitting unit 1. Although the amount of light reflected by the touch metal line 24-1 from other color light-emitting units 2 increases, the reduction in the amount of light reflected by the touch metal line 24-1 from the selected color light-emitting unit 1 is greater than the increase in the amount of light reflected by the touch metal line 24-1 from other color light-emitting units 2. Therefore, the amount of light reflected by the touch metal line 24-1 in the optical sensing area CC from the light-emitting unit 123-1 is reduced, which in turn reduces the amount of light reflected by the touch metal line 24-1 into the optical sensor 400. This reduces the interference caused by the light emitted by the light-emitting unit 123-1 being reflected into the optical sensor 400 by the touch metal line 24-1, effectively improving the sensing capability of the optical sensor 400. This allows the display product to automatically and quickly adjust the screen brightness, ensuring the reliability of the display product.

[0147] For example, as shown in FIG15A and referring to FIG8A, the four touch metal lines 24-1 around the selected color light-emitting part 1 are all extended outward to the side away from the selected color light-emitting part 1, that is, the distance y from the four touch metal lines 24-1 to the selected color light-emitting part 1 is increased. The distance y from the four touch metal lines 24-1 to the selected color light-emitting part 1 is greater than the distance x from the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1 to the selected color light-emitting part 1.

[0148] For example, as shown in FIG15A, the orthographic projection of the touch metal line 24-1 on the light-emitting layer 123 is located between adjacent light-emitting parts 123-1. This can be understood as a selected color light-emitting part 1 located on one side of the touch metal line 24-1, and a different color light-emitting part 2 located on the other side of the touch metal line 24-1. Since the distance y from the touch metal line 24-1 to the selected color light-emitting part 1 located on one side of it increases, the distance z from the touch metal line 24-1 to the other color light-emitting part 2 located on the other side of it will decrease. That is, the distance z from the four touch metal lines 24-1 around the other color light-emitting part 2 to the other color light-emitting part 2 is less than the distance x from the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1 to the selected color light-emitting part 1.

[0149] For example, as shown in FIG15A, the selected color light-emitting part 1 is, for example, a first color light-emitting part G, and the other color light-emitting parts 2 are, for example, a second color light-emitting part B and a third color light-emitting part R. For example, the maximum emission angle of the light emitted by the second color light-emitting part B is greater than the maximum emission angle of the light emitted by the third color light-emitting part R, that is, the light emitted by the second color light-emitting part B is more divergent than the light emitted by the third color light-emitting part R. When the distance of the touch metal line 24-1 from the second color light-emitting part B and the third color light-emitting part R is equal, the amount of reflection of the light emitted by the touch metal line 24-1 on the second color light-emitting part B is greater than the amount of reflection of the light emitted by the third color light-emitting part R. Therefore, the distance z1 from the touch metal line 24-1 around the second color light-emitting part B to the second color light-emitting part B can be set to be greater than the distance z2 from the touch metal line 24-1 around the third color light-emitting part R to the third color light-emitting part R.

[0150] This can further reduce the amount of light emitted by the light-emitting part 123-1 of the optical sensing area CC that shines on the touch metal line 24-1, thereby reducing the amount of light reflected from the touch metal line 24-1 into the optical sensor 400. This reduces the interference caused by the light emitted by the light-emitting part 123-1 being reflected from the touch metal line 24-1 into the optical sensor 400, effectively improving the sensing capability of the optical sensor 400. This allows the display product to automatically and quickly adjust the screen brightness, ensuring the reliability of the display product.

[0151] For example, as shown in FIG15B and referring to FIG8B, the portion around the selected color light-emitting part 1, for example, the two touch metal lines 24-1 extend outward away from the selected color light-emitting part 1, that is, the distance y from the two touch metal lines 24-1 to the selected color light-emitting part 1 increases, while the distance from the remaining two touch metal lines 24-1 to the selected color light-emitting part 1 remains unchanged; the distance y from the two touch metal lines 24-1 to the selected color light-emitting part 1 is greater than the distance x from the touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1 to the selected color light-emitting part 1.

[0152] For example, the distance z from the touch metal line 24-1 around the other color light-emitting part 2 to the other color light-emitting part 2, and the distance z1 from the touch metal line 24-1 around the second color light-emitting part B to the second color light-emitting part B, and the distance z2 from the touch metal line 24-1 around the third color light-emitting part R to the third color light-emitting part R, are as described above and will not be repeated here.

[0153] It is understood that the distances that are increased or decreased can be designed according to the actual situation. The distances that are increased from the touch metal lines 24-1 around the selected color light-emitting part 1 to the selected color light-emitting part 1 can be the same or different; the distances that are decreased from the touch metal lines 24-1 around the other color light-emitting parts 2 to the other color light-emitting parts 2 can be the same or different; this disclosure does not impose any restrictions.

[0154] The specific structures in some of the above embodiments can be combined in any suitable manner in one or more embodiments or examples.

[0155] In some embodiments, as shown in Figures 16A and 16B, and referring to Figures 8A and 8B, the width c1 of the touch metal line 24-1 around the selected color light-emitting part 1 in the optical sensing area CC is equal to the width c2 of the touch metal line 24-1 around other color light-emitting parts 2. That is, the widths c1 / c2 of all touch metal lines 24-1 in the optical sensing area CC are equal and all are smaller than the width a of the touch metal line 24-1 in the main display area AA1. The distance from at least some of the touch metal lines 24-1 around the selected color light-emitting part 1 in the optical sensing area CC to the selected color light-emitting part 1 is greater than the distance from the touch metal lines 24-1 around the selected color light-emitting part 1 in the main display area AA1 to the selected color light-emitting part 1. The distance from at least some of the touch metal lines 24-1 around other color light-emitting parts 2 to the other color light-emitting parts 2 is less than the distance from the touch metal lines 24-1 around the other color light-emitting parts 2 in the main display area AA1 to the other color light-emitting parts 2.

[0156] In some embodiments, as shown in Figures 17A and 17B, and referring to Figures 8A and 8B, the width d2 of the partial touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC is smaller than the width a of the partial touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1, and the width d1 of the partial touch metal lines 24-1 around the selected color light-emitting part 1 is greater than or equal to the width a of the partial touch metal lines 24-1 around the selected color light-emitting part 1 of the main display area AA1; the width e1 of the partial touch metal lines 24-1 around the partial other color light-emitting parts 2 of the optical sensing area CC... The width a of the touch metal lines 24-1 around the other color light-emitting part 2 of the main display area AA1 is greater than or equal to the width a of the touch metal lines 24-1 around the selected color light-emitting part 1 of the optical sensing area CC. The distance from the selected color light-emitting part 1 to the selected color light-emitting part 1 is greater than the distance from the selected color light-emitting part 1 to the selected color light-emitting part 1 of the main display area AA1. The distance from the other color light-emitting part 2 to the other color light-emitting part 2 is less than the distance from the other color light-emitting part 2 to the other color light-emitting part 2 of the main display area AA1.

[0157] In some embodiments, as shown in Figures 18A and 18B, and referring to Figures 8A and 8B, the number of breaks in the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC is greater than the number of breaks in the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1; the number of breaks in the touch metal lines 24-1 around the other color light-emitting portions 2 of the optical sensing area CC is greater than the number of breaks in the touch metal lines 24-1 around the other color light-emitting portions 2 of the main display area AA1; the distance from at least a portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC to the selected color light-emitting portion 1 is greater than the distance from the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1 to the selected color light-emitting portion 1; and the distance from at least a portion of the touch metal lines 24-1 around the other color light-emitting portions 2 to the other color light-emitting portions 2 is less than the distance from the touch metal lines 24-1 around the other color light-emitting portions 2 of the main display area AA1 to the other color light-emitting portions 2.

[0158] In some embodiments, as shown in Figures 19A and 19B, and referring to Figures 8A and 8B, the width c1 of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 in the optical sensing area CC is equal to the width c2 of the touch metal lines 24-1 surrounding other color light-emitting parts 2. That is, the widths c1 / c2 of all touch metal lines 24-1 in the optical sensing area CC are equal, and all are smaller than the width a of the touch metal lines 24-1 in the main display area AA1. The distance from at least a portion of the touch metal lines 24-1 surrounding the selected color light-emitting part 1 in the optical sensing area CC to the selected color light-emitting part 1 is greater than the distance from the touch metal lines 24-1 surrounding the selected color light-emitting part 1 in the main display area AA1 to the selected color light-emitting part 2. The distance between the selected color light-emitting part 1 and the distance between at least a portion of the touch metal lines 24-1 around the other color light-emitting part 2 and the other color light-emitting part 2 is less than the distance between the touch metal lines 24-1 around the other color light-emitting part 2 in the main display area AA1; the number of breaks in the touch metal lines 24-1 around the selected color light-emitting part 1 in the optical sensing area CC is greater than the number of breaks in the touch metal lines 24-1 around the selected color light-emitting part 1 in the main display area AA1; the number of breaks in the touch metal lines 24-1 around the other color light-emitting part 2 in the optical sensing area CC is greater than the number of breaks in the touch metal lines 24-1 around the other color light-emitting part 2 in the main display area AA1.

[0159] In some embodiments, as shown in Figures 20A and 20B, and referring to Figures 8A and 8B, the width d2 of a portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC is smaller than the width a of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1, and the width d1 of the portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 is greater than or equal to the width a of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the main display area AA1; the width e1 of a portion of the touch metal lines 24-1 around a portion of other color light-emitting portions 2 of the optical sensing area CC is greater than or equal to the width a of the touch metal lines 24-1 around the other color light-emitting portions 2 of the main display area AA1; at least a portion of the touch metal lines 24-1 around the selected color light-emitting portion 1 of the optical sensing area CC...
