The substrate includes a plurality of touch areas and an optical element area. The plurality of pixel electrodes are disposed on the surface of the substrate and are located in the optical element area. The plurality of touch sensing electrodes are disposed on the surface of the substrate and are located in the plurality of touch areas. The first routing line is disposed on the surface of the substrate and electrically connects the plurality of pixel electrodes. At least one of the plurality of touch areas partially overlaps with the optical element area, wherein the optical element area includes a plurality of optical sensing areas and a plurality of display areas. One of the plurality of optical sensing areas is located between two adjacent ones of the plurality of display areas, one of the plurality of display areas is located between two adjacent ones of the plurality of optical sensing areas, and the plurality of display areas and the plurality of optical sensing areas are staggered in one direction.

[0005] Based on the above, in the electronic device of the disclosed embodiment, since the optical element overlaps the optical element area, and the optical element area includes a display area and an optical sensing area. Therefore, the electronic device has an application of good display or good optical detection. In addition, since the wiring extends into the optical element area to drive the electrode in the optical sensing area, and another wiring drives the electrode in the touch area outside the optical element area, the other wiring outside the optical element area has less influence on the wiring arrangement in the optical element area, and the pixel opening rate in the optical element area can be improved. The electronic device of this embodiment can achieve good display, optical detection or touch effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] It should be understood that when a component or film layer is referred to as being "connected to" another component or film layer, it can be directly connected to the other component or film layer, or there can be an intervening component or film layer between the two. When a component is referred to as being "directly connected to" another component or film layer, there can be no intervening components or film layers between the two. In addition, when a component is referred to as being "coupled to another component (or variant thereof)", it can be directly connected to the other component, indirectly connected (e.g., electrically connected) to the other component through one or more components.

[0060] In the present disclosure, the length and width can be measured by optical microscopy, and the thickness can be measured by cross-sectional images in an electron microscope, but the present invention is not limited thereto.

[0068] Figure 1A FIG. 1 is a schematic top view of an electronic device according to an embodiment of the present disclosure. Figure 1B It is a partial enlarged schematic diagram of a touch area and an optical element area of ​​an electronic device according to an embodiment of the present disclosure. Figure 2 for Figure 1B A schematic cross-sectional view of an electronic device along the section line AA'. For the sake of clarity and convenience of description, Figure 1A , Figure 1B and Figure 2 Some components are omitted. Figure 1A and Figure 1B, the electronic device 10 may include a display panel composed of a substrate 100, a plurality of electrodes PX, a plurality of electrodes RX, a line SL1, and a line SL2. The substrate 100 may include an optical element area 11 and a plurality of touch areas 12. That is, the electronic device 10 may be an application of a touch display panel. In some embodiments, at least one of the plurality of touch areas 12 may partially overlap with the optical element area 11, but is not limited thereto. A plurality of electrodes PX are disposed on the substrate 100 and are located in the optical element area 11. A plurality of electrodes RX are disposed on the substrate 100 and are respectively located in the plurality of touch areas 12. A plurality of lines SL1 are disposed on the substrate 100 and are respectively electrically connected to the plurality of electrodes PX. A plurality of lines SL2 are disposed on the substrate 100 and are respectively electrically connected to the plurality of electrodes RX. Under the above-mentioned configuration, the electronic device 10 may have good optical quality or good touch performance. In the present embodiment, the substrate 100 may include predetermined areas R1, R2, and R3. For example, the predetermined area R1 can be defined as the edge portion of the substrate 100 close to the electronic device 10, the predetermined area R2 can be defined as the corner portion of the substrate 100 close to the electronic device 10, and the predetermined area R3 can be defined as the portion of the substrate 100 away from the edge of the electronic device 10, but it is not limited thereto. The optical element area 11 can be disposed in one of the predetermined areas R1, R2, and R3. In the present disclosure, the optical element area 11 is disposed in / or located in one of the predetermined areas R1, R2, and R3 and can be defined as: the optical element area 11 overlaps at least part of the predetermined areas R1, R2, and R3 in the normal direction Z of the substrate 100, but it is not limited thereto. In other embodiments, the definition of other elements located in other areas can also be defined in the above manner, so it will not be repeated below. For example, the optical element area 11 can be substantially the same size as the predetermined areas R1, R2, and R3, and at this time, the optical element area 11 and the predetermined areas R1, R2, and R3 almost completely overlap. In some embodiments, the size of the optical element area 11 may be smaller than the size of the predetermined areas R1, R2, and R3. In this case, the optical element area 11 overlaps with a portion of the predetermined areas R1, R2, and R3, but the projection of the optical element area 11 on the substrate 100 must be within the projection of the predetermined areas R1, R2, and R3 on the substrate 100. In other embodiments, the substrate 100 may include a plurality of optical element areas 11 disposed in / or located in at least one of the predetermined areas R1, R2, and R3, but is not limited thereto.

[0069] Please refer to Figure 1A and Figure 1B ,by Figure 1BFor example, the optical element area 11 is disposed in the predetermined area R1. The plurality of touch areas 12 are arranged in a plurality of columns along the Y axis or in a plurality of rows along the X axis in an array manner, and a portion of the plurality of touch areas 12 may be located in the predetermined area R1, and another portion may be located on the substrate 100 outside the predetermined area R1, but the invention is not limited thereto. In the present embodiment, one of the plurality of touch areas 12 partially overlaps with the optical element area 11. In the present embodiment, the X axis is perpendicular to the Y axis or the Z axis, and the Y axis is perpendicular to the X axis or the Z axis.

[0070] In the present embodiment, the plurality of electrodes RX are respectively located in the plurality of touch regions 12. Specifically, the plurality of electrodes RX may overlap the plurality of touch regions 12, and the electrode RX1, the electrode RX2, the electrode RX3, and the electrode RX4 may be arranged from top to bottom on the Y axis. In the present embodiment, the electrode RX is, for example, applied as a touch sensing electrode, but the present invention is not limited thereto. In this way, the electronic device 10 may have a touch function application.

[0071] The plurality of electrodes PX are arranged on the substrate 100 in an array manner, and the plurality of electrodes PX may overlap at least one of the plurality of electrodes RX and / or the plurality of touch regions 12. Figure 1B For example, multiple electrodes PX overlap multiple electrodes RX and / or one of the multiple touch areas 12, and multiple electrodes PX are located in the optical element area 11 and extend along the Y axis and are arranged in multiple straight lines on the X axis, and at least partially overlap the optical element area 11 on the Z axis, but not limited to this.

[0072] The electronic device 10 disclosed herein further includes a plurality of pixel electrodes PE disposed in an array on the substrate 100, and the plurality of pixel electrodes PE may overlap at least one of the plurality of electrodes RX and / or the plurality of touch regions 12. Figure 1B As shown, the pixel electrode PE1, the pixel electrode PE2 and the pixel electrode PE3 may extend along the Y axis respectively and be arranged in a plurality of straight lines on the X axis. In addition, on the X axis, the pixel electrode PE and the electrode PX may be disposed adjacent to each other, but are not limited thereto. For example, on the X axis, the electrode PX may be disposed between the pixel electrode PE1 and the pixel electrode PE2. That is, the pixel electrode PE and the electrode PX may be disposed alternately on the X axis, but the present embodiment is not limited thereto. In the present embodiment, the pixel electrode PE1 is, for example, a red pixel electrode, the pixel electrode PE2 is, for example, a green pixel electrode, and the pixel electrode PE3 is, for example, a blue pixel electrode, but are not limited thereto. The electrode PX may also be a pixel electrode, which is used to regulate changes in optical signals, but is not limited thereto.

[0073] In the present embodiment, the area where any one of the plurality of pixel electrodes PE (e.g., pixel electrode PE1, pixel electrode PE2, or pixel electrode PE3) overlaps the substrate 100 on the Z axis may define a display area DA. The area where any one of the plurality of electrodes PX overlaps the substrate 100 on the Z axis may define an optical sensing area SA. In the present embodiment, the display area DA and the optical sensing area SA may be located in the optical element area 11.

[0074] The display area DA is, for example, defined as an active matrix driving mode, which can be responsible for controlling the color of the pixel electrode PE and adjusting the change of the displayed image. The color of the pixel electrode PE can be selected by the corresponding photoresist material to allow the corresponding wavelength of light to pass through, and the light and dark changes can be adjusted by the liquid crystal material. In some embodiments, in the detection mode, the display area DA can be in a dark state (also called an OFF state) that absorbs or blocks light through the liquid crystal material, and the optical sensing area SA is used to enable the optical element (overlapping the optical element area 11, which will be described later) to have a sensing function. However, in other embodiments, in the detection mode, the display area SA can also be in a light-transmitting bright state (also called an ON state), and the use of color additive mixing (for example, red, green and blue light are mixed into white light) can increase the reception or emission of optical signals by the optical element.

[0075] The optical sensing area SA is, for example, defined as an active (or passive) matrix driving mode, which has a dark state of light absorption or light blocking (also referred to as an OFF state, in which light does not substantially pass through the optical sensing area SA) or a light-transmitting bright state (also referred to as an ON state, in which light can pass through the optical sensing area SA) to serve as a switch that can adjust the amount of light entering (or outgoing) the optical element. Light can penetrate the optical sensing area SA. The optical sensing area SA may include a transparent photoresist, a white photoresist, or no photoresist, and adjust the light and dark changes through a liquid crystal material to increase the optical element's reception or emission of optical signals. In some embodiments, the optical sensing area SA may be defined as an optical signal whose wavelength does not substantially change after passing through the optical sensing area SA, or the color perceived by the human eye does not substantially change, but is not limited thereto.

[0076] In the present embodiment, in the optical element area 11, since any one of the plurality of pixel electrodes PE overlaps the display area DA and can have a display application, the display area DA and the pixel electrode PE can define a sub-pixel SP1, but the present invention is not limited thereto. Any one of the plurality of electrodes PX overlaps the optical sensing area SA and can have a light-transmitting application, so the optical sensing area SA and the electrode PX can define an optical pixel. In the present embodiment, the area of ​​the display area DA on the Z axis can be substantially equal to the area of ​​the optical sensing area SA on the Z axis, but the present invention is not limited thereto. Thus, the optical element area 11 (provided with the sub-pixel SP1 and / or the optical pixel) can have a display function and / or an optical function.

[0077] Since the electrode RX of this embodiment can also be applied as a common electrode, the pixel electrode PE and the electrode PX can control the rotation of the liquid crystal molecules in the liquid crystal layer LC to be applied as a display panel. Under the above configuration, the electronic device 10 can have an application of an in-cell touch display panel that integrates a touch function into the display panel.

[0078] The following will be passed Figure 1B and Figure 2 The structure of the electronic device 10 will be briefly described.

In some embodiments, when the substrate 100 is a flexible substrate, it may include a suitable flexible material, such as polycarbonate (PC), polyimide (PI), polypropylene (PP) or polyethylene terephthalate (PET), other suitable materials or a combination of the foregoing materials, but is not limited thereto. In addition, the light transmittance of the substrate 100 is not limited, that is, the substrate 100 may be a light-transmitting substrate, a semi-transmitting substrate or an opaque substrate.

[0080] The insulating layer disposed on the surface 101 of the substrate 100 may be a single-layer or multi-layer structure, and may include, for example, an organic material (such as silicon nitride), an inorganic material, or a combination thereof, but is not limited thereto.

[0081] In the present embodiment, a light shielding structure LS may be disposed on the substrate 100.

[0082] The electronic device 10 may include a transistor T having a semiconductor layer SEMI. The transistor T is, for example, a thin film transistor. The material of the semiconductor layer SEMI, for example, includes a thin film transistor of amorphous silicon, low temperature polysilicon (LTPS) or metal oxide, or a combination of the above materials, but the present disclosure is not limited thereto.

In the present embodiment, the semiconductor layer SEMI includes a channel region CH, and the gate G is disposed corresponding to the channel region CH. In some embodiments, the above-mentioned light shielding structure LS is, for example, disposed corresponding to the channel region CH, but is not limited thereto. In the present embodiment, the material of the gate G may include molybdenum (Mo), titanium (Ti), tantalum (Ta), niobium (Nb), hafnium (Hf), nickel (Ni), chromium (Cr), cobalt (Co), zirconium (Zr), tungsten (W), aluminum (Al), copper (Cu), silver (Ag), other suitable metals, or alloys or combinations of the above materials, but not limited thereto.

[0084] In the present embodiment, the insulating layers 130, 140, 150, 160, and 170 may be sequentially arranged on the transistor T. The trace SL1 and the trace SL2 may be arranged on the insulating layer 150 and are substantially located at the same horizontal plane, but not limited thereto. In the present embodiment, the trace SL1 and the trace SL2 are made of the same film layer, that is, the arrangement of the trace SL1 and the trace SL2 may be completed in the same process. In this way, the manufacturing process may be simplified, the manufacturing cost may be saved, or the electronic device 10 may be thinned. The material of the trace SL1 and the trace SL2 may include a transparent conductive material or a non-transparent conductive material, such as indium tin oxide, indium zinc oxide, indium oxide, zinc oxide, tin oxide, metal materials (such as aluminum, molybdenum, copper, silver, etc.), other suitable materials, or a combination thereof, but not limited thereto.

[0085] The electrode RX may be disposed on the insulating layer 160. The electrode RX of this embodiment is, for example, a touch sensing electrode or a common electrode. The insulating layer 160 may have a through hole VA2, and the through hole VA2 may be located in the display area DA. The electrode RX may be electrically connected to the trace SL2 through the through hole VA2.

[0086] The electrode PX (also referred to as the first electrode) may be disposed on the insulating layer 170. The electrode PX of the present embodiment is, for example, an electrode for controlling the liquid crystal material in the optical sensing area SA. The insulating layers 160 and 170 may have a through hole VA1 (also referred to as the first through hole), and the through hole VA1 is located in the optical sensing area SA. The electrode PX may be electrically connected to the trace SL1 (also referred to as the first trace) through the through hole VA1.

[0087] The pixel electrode PE may be disposed in the same layer as the electrode PX and located on the insulating layer 170.

The insulating layers 130, 140, 150, 160, 170 may have a through hole VA3, and the pixel electrode PE may be electrically connected to the drain D of the transistor T through the through hole VA3. Thereby, the electrode PX and the pixel electrode PE may respectively control the liquid crystal molecules in the optical sensing area SA and the display area DA, and have an optical effect of display or light transmission. In some embodiments, the electrode PX may also be electrically connected to other transistors through the wiring SL1, and driven in an active matrix manner.

The liquid crystal layer LC includes a plurality of liquid crystal molecules that can be driven by the electric field of the electrode PX or the pixel electrode PE to rotate, so as to adjust the polarization state of light passing through the display area DA or the optical sensing area SA.

[0090] The electronic device 10 may further include a light shielding layer BM, a color filter layer CF1, a light-transmitting layer CF2, a planar layer 210, and an alignment layer 220 disposed on the opposite substrate 200. The color filter layer CF1 and the light-transmitting layer CF2 may be disposed between the opposite substrate 200 and the planar layer 210, and the color filter layer CF1 may overlap the display area DA, and the light-transmitting layer CF2 may overlap the optical sensing area SA. In the present embodiment, the opposite substrate 200 includes, for example, glass, quartz, ceramic, sapphire, or plastic, but the present disclosure is not limited thereto. In another embodiment, the material of the opposite substrate 200 may include a suitable opaque material. In some embodiments, when the opposite substrate 200 is a flexible substrate, it may include a suitable flexible material, such as polycarbonate (PC), polyimide (PI), polypropylene (PP), or polyethylene terephthalate (PET), other suitable materials, or a combination of the foregoing materials, but is not limited thereto. In addition, the light transmittance of the opposite substrate 200 is not limited, that is, the opposite substrate 200 can be a light-transmitting substrate, a semi-light-transmitting substrate, or a light-impermeable substrate.

[0091] In the present embodiment, the material of the color filter layer CF1 may include a colored photoresist or other suitable materials. The material of the light-transmitting layer CF2 may include a transparent photoresist, a white photoresist or other suitable materials. In some embodiments, the light-transmitting layer CF2 may not be provided. The material of the light-shielding layer BM may include an opaque material, such as metal, opaque resin or opaque photoresist, but is not limited thereto. In the present embodiment, the counter substrate 200 may be used as a color filter substrate, for example, but is not limited thereto.

[0092] The electronic device 10 of the present embodiment may further include a spacer 190 (photospacer, PS). The spacer 190 is disposed between the substrate 100 and the opposite substrate 200, and may be disposed corresponding to the transistor T, the trace SL2 or the via VA2, but is not limited thereto. The material of the spacer 190 may include a photoresist material, polyimide, other suitable materials, or a combination thereof, but is not limited thereto.

[0093] In the present embodiment, the electronic device 10 may further include an optical element 300 and a backlight module 400. The optical element 300 may be disposed on another surface 102 of the substrate 100 relative to the surface 101 and located in the optical element area 11. For example, the area where the optical element 300 overlaps the substrate 100 on the Z axis may define the optical element area 11. In the present embodiment, the optical element 300 partially overlaps the display area DA and the optical sensing area SA. The optical element 300 may be a camera, a flash, an infrared (IR) light source, an infrared sensor, other sensors, an electronic element, or a combination thereof, but is not limited thereto. Under the above configuration, the electronic device 10 may have a camera under display (CUD), an under-screen flash, an under-screen soft light, an under-screen infrared face recognition system, an under-screen infrared iris recognition system, other functions, or a combination of the above functions, but is not limited thereto.

[0094] In this embodiment, the backlight module 400 can overlap the optical element area 11 and the plurality of touch areas 12 of the substrate 100 to be used as a light source for the electronic device 10. The backlight module 400 can be disposed on the other surface 102 of the substrate 100. The backlight module 400 includes, for example, a light source of a light emitting diode (LED) or other suitable light sources, but is not limited thereto.

[0095] It is worth noting that, since the plurality of liquid crystal molecules in the liquid crystal layer LC can be driven by the electric field of the electrode PX or the pixel electrode PE to adjust the polarization state of the light passing through the display area DA or the optical sensing area SA. Therefore, the electronic device 10 can switch the display area DA to a bright state to display an image in the display mode, and switch the optical sensing area SA to a dark state. In the display mode, the optical element 300 is in a closed state (for example, not powered or not operating). Thereby, the optical signal entering the optical element 300 or the optical signal emitted by the optical element 300 can be reduced. In addition, the electronic device 10 can also switch the display area DA to a dark state in the detection mode to reduce the impact on the optical element 300, and switch the optical sensing area SA to a bright state. In the detection mode, the optical element 300 is in an open state (for example, powered or operating). Thereby, the optical signal entering the optical element 300 or the optical signal emitted by the optical element 300 can be increased, but it is not limited thereto. In some embodiments, in the display mode, the optical sensing area SA may also be switched to a bright state.

[0096] In another embodiment, the electronic device 10 may also switch the display area DA to a bright state in the detection mode, so as to increase the optical signal entering the optical element 300 or increase the optical signal emitted by the optical element 300 by using color additive mixing according to the application. Under the above settings, the electronic device 10 of this embodiment may have the application of an under-screen optical element display panel, and has the application of good optical quality or good optical imaging, optical lighting, optical signal transmission or optical signal recognition, but is not limited thereto.

[0097] also, Figure 1B as well as Figure 2 The electronic device 10 shown can be electrically connected to the electrode PX through the line SL1 and the electrode RX through the line SL2. For example, there can be multiple lines SL1, and they extend from the top of the substrate 100 to the bottom along the Y axis into the optical element area 11. The line SL1 can extend into the optical sensing area SA and be electrically connected to the electrode PX through the through hole VA1. In this way, the optical pixel corresponding to the optical sensing area SA and the electrode PX can be driven by the line SL1, and switched to a bright state in the detection mode so that light can penetrate the light-transmitting layer CF2 to increase the optical signal entering the optical element 300 or increase the optical signal emitted by the optical element 300. In this embodiment, the line SL1 can be coupled to other electronic components to drive the electrode PX. The electronic component includes, for example, a chip, a flexible printed circuit board, or a chip on film (COF), but is not limited thereto. In some other embodiments, the trace SL1 may also be coupled to a transistor array disposed corresponding to the electrode PX through the via VA1 to drive the electrode PX in an active matrix driving manner.

[0098] It is worth noting that in the electronic device 10 shown in the present embodiment, the trace SL2 may be located outside the optical element area 11 or disposed adjacent to the optical element area 11. For example, the trace SL21, trace SL22, trace SL23, and trace SL24 may be arranged in the X-axis direction, and the trace SL21, trace SL22, trace SL23, and trace SL24 may respectively extend from the bottom of the substrate 100 to the top along the Y-axis into the corresponding touch area 12 and be electrically connected to the electrode RX. For example, the trace SL21 may extend and be electrically connected to the corresponding electrode RX1, the trace SL22 may extend and be electrically connected to the corresponding electrode RX2, the trace SL23 may extend and be electrically connected to the corresponding electrode RX3, and the trace SL24 may extend and be electrically connected to the corresponding electrode RX4. At least one of the wiring SL21 , the wiring SL22 , the wiring SL23 , and the wiring SL24 may be electrically connected to at least one of the electrode RX1 , the electrode RX2 , the electrode RX3 , and the electrode RX4 through the through hole VA2 , respectively.

[0099] In the present embodiment, the optical element area 11 overlaps the upper side of the electrode RX1. Since there is a need to set the trace SL1 on the electrode RX1 corresponding to the overlap of the optical element area 11, the trace SL21 can extend into the electrode RX1 and then turn to extend on the X-axis and be electrically connected to the electrode RX1 through a plurality of through holes VA2. In the present embodiment, the trace SL21 or the through hole VA2 is located outside the optical element area 11 or is disposed adjacent to the optical element area 11, so that the trace SL2 has less influence on the arrangement of the trace SL1 in the optical element area 11, and the pixel opening ratio of the display area DA and the optical sensing area SA can be increased. In addition, since the trace SL1 and the trace SL2 are made of the same film layer, they can be made through the existing process, which has the effect of simplifying the process or reducing the cost.

[0100] In addition, since the line SL21 can be electrically connected to the electrode RX1 through the opening VA2 outside the optical element area 11 or adjacent to the optical element area 11, the touch signal can be transmitted to the electrode RX1 through the line SL21. In this embodiment, the signal transmission direction EP can be to transmit the signal from bottom to top on the Y-axis. In this way, the touch signal can be transmitted from the lower side of the electrode RX1 to the upper side of the electrode RX1 in the signal transmission direction EP. Thereby, the electronic device 10 can achieve the effect of display, optical detection or touch. Based on the above, the electronic device 10 can have good optical quality or good touch performance.

[0101] It should be noted here that Figure 1B The number, density, shape or arrangement of the plurality of through holes VA1 or VA2 is schematically shown for illustration purposes. In other embodiments, the number, density, shape or arrangement of the through holes VA1 or VA2 may be adjusted as appropriate. Figure 1B Limits shown.

[0102] In short, in the electronic device 10 of the present embodiment, since the optical element 300 overlaps the optical element area 11, and the optical element area 11 includes the display area DA and the optical sensing area SA, the electronic device 10 can have display or optical detection applications. In addition, since the trace SL1 extends into the optical element area 11 to drive the electrode PX in the optical sensing area SA, and the trace SL2 drives the electrode RX in the touch area 12 outside the optical element area 11 or adjacent to the optical element area 11, the trace SL2 has less influence on the trace arrangement in the optical element area 11, and the pixel opening rate of the optical element area 11 can be improved. The trace SL1 and the trace SL2 can be arranged on the same layer, so the process can be simplified or the manufacturing cost can be reduced.

[0103] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component numbers and some contents of the previous embodiments, wherein the same numbers are used to represent the same or similar components, and the description of the same technical contents is omitted. The description of the omitted parts can be referred to the previous embodiments, and the following embodiments will not be repeated.

[0104] Figure 3 This is a partial enlarged schematic diagram of the touch area and optical element area of ​​an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 3 Some components are omitted from the illustration. The electronic device 10A of this embodiment is substantially similar to Figure 1B The electronic device 10 of the present invention is described above, and therefore the same and similar components in the two embodiments will not be repeated here. The main difference between this embodiment and the electronic device 10 is that the optical element area 11 overlaps the right side of the electrode RX, so the trace SL2 can extend on the Y axis into the left side of the electrode RX overlapping the optical element area 11. The trace SL2 can be located outside the optical element area 11 or disposed adjacent to the optical element area 11, and electrically connected to the electrode RX through a plurality of through holes VA2 on the Y axis. In this embodiment, the signal transmission direction EP can be to transmit the signal from left to right on the X axis, but is not limited to this. In this way, the touch signal can be transmitted from the left side of the electrode RX to the right side of the electrode RX in the signal transmission direction EP. Thereby, the electronic device 10A can achieve the effect of display, optical detection or touch, but is not limited to this. In addition, the electronic device 10A can obtain excellent technical effects similar to those of the above-mentioned embodiments.

[0105] In some embodiments (not shown), the optical element area 11 may not overlap the left side and the bottom side of the electrode RX, for example, it may overlap the upper right side of the electrode RX. Therefore, after the line SL2 extends into the electrode RX overlapping the optical element area 11 on the Y axis, it may extend along the Y axis on the left side of the electrode RX and extend along the X axis on the bottom side of the electrode RX. The line SL2 may be located outside the optical element area 11 or disposed adjacent to the optical element area 11, and electrically connected to the electrode RX through a plurality of through holes VA2 on the Y axis and the X axis. Thereby, the signal transmission direction EP may include transmitting the signal from left to right on the X axis and transmitting the signal from bottom to top on the Y axis. In this way, the touch signal can be transmitted from the left side and the bottom side of the electrode RX to the upper right side of the electrode RX. Thereby, an excellent technical effect similar to the above-mentioned embodiment can be obtained.

[0106] In other embodiments (not shown), the area of ​​the optical element area 11 may also be smaller than the area of ​​the electrode RX, and substantially overlap the middle part of the electrode RX. Therefore, after the trace SL2 extends into the electrode RX overlapping the optical element area 11 on the Y axis, it may extend upward along the Y axis on the left side of the electrode RX, and extend rightward along the X axis on the lower side of the electrode RX and then extend upward along the Y axis. In other words, the trace SL2 may be located outside the optical element area 11 or adjacent to the optical element area 11 and surround the optical element area 11 in a U shape. The trace SL2 is electrically connected to the electrode RX through a plurality of through holes VA2 on the Y axis and the X axis. Thereby, the signal transmission direction EP includes transmitting the signal from left to right or from right to left on the X axis, and transmitting the signal from bottom to top on the Y axis. In this way, the touch signal can be transmitted from the left side, right side or bottom side of the electrode RX to the middle part of the electrode RX. Thereby, an excellent technical effect similar to the above-mentioned embodiment can be obtained.

[0107] Figure 4 This is a partial enlarged schematic diagram of the touch area and optical element area of ​​an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 4 Some components are omitted from the illustration. The electronic device 10B of this embodiment is substantially similar to Figure 3 Therefore, the same and similar components of the two embodiments are not repeated here. The main difference between this embodiment and the electronic device 10A is that the optical element area 11 can be set as follows Figure 1A In the predetermined area R2 shown, the area of ​​the optical element area 11 may be larger than the area of ​​the electrode RX. In this embodiment, the electrode RX overlapping the optical element area 11 may be extended to the left on the X-axis, so that its area may be larger than the area of ​​the adjacent electrode RX. A plurality of dummy pixels PD (dummy pixels) may be arranged on the left side of the electrode RX that does not overlap the optical element area 11.

[0108] In the present embodiment, a plurality of through holes VA2 may be respectively located in a plurality of dummy pixels PD, and the trace SL2 may be electrically connected to the electrode RX through the through hole VA2 on the Y axis. In the present embodiment, the signal transmission direction EP may be to transmit the signal from left to right on the X axis. In this way, the touch signal may be transmitted from the left side of the electrode RX to the right side of the electrode RX in the signal transmission direction EP. In this way, the electronic device 10B may achieve the effects of display, optical detection or touch in the optical element area 11, but is not limited thereto. In addition, the electronic device 10B may obtain excellent technical effects similar to those of the above-mentioned embodiments.

[0109] In some embodiments (not shown), other wirings may enter the left side of the electrode RX to be electrically connected to the electrode RX through the through hole VA2 outside the optical element area 11. Other wirings may include wirings (e.g., wirings for transmitting a common voltage) or power lines surrounding the display area at the edge of the substrate 100, but are not limited thereto. In this way, excellent technical effects similar to those of the above-mentioned embodiments may be obtained.

[0110] Figure 5 This is a partial enlarged schematic diagram of the touch area and optical element area of ​​an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 5 Some components are omitted from the illustration. The electronic device 10C of this embodiment is substantially similar to Figure 1B Therefore, the same and similar components of the two embodiments are not repeated here. The main difference between this embodiment and the electronic device 10 is that the optical element area 11 can be set as follows Figure 1A In the predetermined area R1 shown in FIG. 1 , the electrode RXC overlapping the optical element area 11 may be extended to the right on the X-axis, so that its area may be larger than the area of ​​the electrode RX in the adjacent touch control area 12. For example, the area of ​​the electrode RXC may be greater than or equal to twice the area of ​​the electrode RX, and may span across two electrodes RX located in the same horizontal row.

[0111] In the present embodiment, the trace SL2 may extend into the electrode RXC on the Y axis and be electrically connected to the electrode RXC through the through hole VA2 on the right side outside the optical element area 11. In the present embodiment, the signal transmission direction EP may be to transmit the signal from left to right or from right to left on the X axis. In this way, the touch signal may be transmitted from the right side of the electrode RX to the left side of the electrode RX, or from the right side of the electrode RX to the right to the right edge of the electrode RX in the signal transmission direction EP. Thereby, the electronic device 10C may achieve the effects of display, optical detection or touch, but is not limited thereto. In addition, the electronic device 10C may obtain excellent technical effects similar to those of the above-mentioned embodiments.

[0112] In some embodiments (not shown), the optical element area 11 may be arranged as follows: Figure 1AThe area in the predetermined area R1 shown, but outside the predetermined area R2. Taking three straight columns of electrodes RX as an example, the electrodes RX in the uppermost horizontal row may include an electrode RX extending to the left and an electrode RX extending to the right. That is to say, the above two electrodes RX may span two straight columns respectively. The optical element area 11 may overlap two electrodes RX. In this embodiment, the routing SL2 may enter the electrode RX extending to the left on the left side outside the optical element area 11, and the touch signal may be transmitted from the left side of the electrode RX extending to the left to the right side of the electrode RX extending to the left. In addition, the routing SL2 may enter the electrode RX extending to the right on the right side outside the optical element area 11, and the touch signal may be transmitted from the right side of the electrode RX extending to the right to the left side of the electrode RX extending to the right. Thereby, the electronic device can achieve the effect of display, optical detection or touch, but is not limited to this.

[0113] Figure 6 This is a partial enlarged schematic diagram of the touch area and optical element area of ​​an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 6 Some components are omitted from the illustration. The electronic device 10D of this embodiment is substantially similar to Figure 1B Therefore, the same and similar components of the two embodiments are not repeated here. The main difference between this embodiment and the electronic device 10 is that the optical element area 11 can be set as follows Figure 1A In the predetermined area R3 shown, the optical element area 11 may overlap four adjacent electrodes RX. For example, the optical element area 11 overlaps the lower right side of the electrode RX1, the upper right side of the electrode RX2, the lower left side of the electrode RX5, and the upper left side of the electrode RX6.

[0114] In this embodiment, the trace SL1 may extend from top to bottom on the Y axis into the optical element region 11, and then extend to the left or right on the X axis to overlap the electrode RX1 and the electrode RX5. Then, the trace SL1 may turn to extend downward on the Y axis to overlap the electrode RX2 and the electrode RX6. In the optical element region 11, the trace SL1 may be electrically connected to the electrode PX through the through hole VA1.

[0115] In this embodiment, the trace SL21 can extend into the electrode RX1 on the Y axis, and be electrically connected to the electrode RX1 through the through hole VA2 on the left side outside the optical element area 11. The trace SL22 can extend into the electrode RX2 on the Y axis, and be electrically connected to the electrode RX2 through the through hole VA2 on the lower side outside the optical element area 11. The trace SL22 can extend on the Y axis or on the X axis on the lower side outside the optical element area 11, thereby improving the strength or quality of the touch signal transmitted in the electrode RX2, but is not limited thereto.

[0116] In this embodiment, the trace SL25 can extend into the electrode RX5 on the Y axis, and be electrically connected to the electrode RX5 through the through hole VA2 on the right side outside the optical element area 11. The trace SL26 can extend into the electrode RX6 on the Y axis, and be electrically connected to the electrode RX6 through the through hole VA2 on the right side outside the optical element area 11.

[0117] In this embodiment, the touch signal can be transmitted from the left side to the right side in the electrode RX1, the touch signal can be transmitted from the lower side to the upper side in the electrode RX2, the touch signal can be transmitted from the right side to the left side in the electrode RX5, and the touch signal can be transmitted from the right side to the left side in the electrode RX6. In this way, the electronic device 10D can achieve the effects of display, optical detection or touch, but is not limited thereto. In addition, the electronic device 10D can obtain excellent technical effects similar to those of the above embodiments.

[0118] In some embodiments (not shown), the optical element area 11 can overlap two adjacent electrodes RX. For example, the optical element area 11 overlaps the right side of the electrode RX2 and the left side of the electrode RX6. The trace SL1 enters the optical element area 11 from the upper side and extends along the X-axis and then extends along the Y-axis to overlap the electrodes RX2 and RX6. The trace SL22 is electrically connected to the electrode RX2 through the through hole VA2 on the left side outside the optical element area 11. The trace SL26 is electrically connected to the electrode RX6 through the through hole VA2 on the right side outside the optical element area 11. Under the above-mentioned setting, the touch signal can be transmitted from the left side to the right side in the electrode RX2, and the touch signal can be transmitted from the right side to the left side in the electrode RX6. In this way, the electronic device can achieve the effect of display, optical detection or touch, but is not limited to this.

[0119] Figure 7 This is a partial enlarged schematic diagram of the touch area and optical element area of ​​an electronic device according to another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 7 Some components are omitted from the illustration. The electronic device 10E of this embodiment is substantially similar to Figure 5 Therefore, the same and similar components of the two embodiments are not repeated here. The main difference between this embodiment and the electronic device 10C is that the optical element area 11 can be set as follows Figure 1A In the predetermined area R3 shown, the optical element area 11 overlaps two adjacent electrodes RX. For example, the optical element area 11 overlaps the electrode RX2 and the electrode RX6 in the second horizontal row from top to bottom. The trace SL1 extends from top to bottom into the optical element area 11 along the Y axis, and extends downward to overlap the electrode RX2. Alternatively, after extending to the right along the X axis, the trace SL1 turns to the Y axis and extends downward to overlap the electrode RX6. The trace SL1 is electrically connected to the electrode PX in the optical element area 11 through the through hole VA1.

[0120] In this embodiment, the electrode RXE is Figure 5 , so it will not be repeated. The area of ​​electrode RXE can be equal to or greater than twice the area of ​​electrode RX, and can span two electrodes RX located on the same horizontal row. Since RXE can span two electrodes RX located on the same horizontal row, and the trace SL21 can be electrically connected to electrode RXE through the through hole VA2, the touch signal can be transmitted from the left side in electrode RXE to the right side in electrode RXE. In addition, trace SL22 is electrically connected to electrode RX2 through the through hole VA2 on the left side outside the optical element area 11. Traverse SL26 enters electrode RX6 on the lower side outside the optical element area 11 and extends to the right or left on the X-axis. Traverse SL26 is electrically connected to electrode RX6 through the through hole VA2 on the lower side outside the optical element area 11. Under the above-mentioned setting, the touch signal can be transmitted from the left side to the right side in electrode RX2, and the touch signal can be transmitted from the lower side to the upper side in electrode RX6. Thereby, the electronic device 10E can achieve the effect of display, optical detection or touch, but is not limited to this. The arrangement or relative relationship of the optical element area 11 and the electrode RX in the above embodiment is only an example. In other embodiments, the overlapping number, overlapping position, arrangement, shape or relative relationship of the optical element area 11 and the electrode RX are not limited and can be adjusted arbitrarily according to the situation. In some embodiments, the optical element area 11 can also be multiple, and can include the same or different optical elements, or have the same or different shapes, sizes, arrangements, positions, relative relationships with the electrode RX, etc. according to the application situation, and the present disclosure does not limit it.

[0121] Figure 8 This is a partial enlarged schematic diagram of the display area and the optical sensing area of ​​another embodiment of the present disclosure. For the sake of clarity and convenience of description, Figure 8 Some components are omitted from the illustration. The electronic device 10F of this embodiment is substantially similar to Figure 1B Therefore, the same and similar components in the two embodiments are not repeated here. The difference between this embodiment and the electronic device 10 is mainly that the arrangement of the pixel electrode PE and the electrode PX in this embodiment is different. Figure 8 Three different arrangements in three regions R4, R5, and R6 are schematically shown. In some embodiments, the electronic device can select at least one arrangement in regions R4, R5, and R6 to be combined arbitrarily, but is not limited thereto.

[0122] like Figure 8As shown, the pixel electrode PE1, the pixel electrode PE2 and the pixel electrode PE3 are arranged adjacently, and three sub-pixels SP2 can be defined respectively. Three sub-pixels SP2 (corresponding to the pixel electrode PE1, the pixel electrode PE2 and the pixel electrode PE3 respectively) can constitute a display pixel P2, but it is not limited thereto. A plurality of electrodes PX are arranged adjacently, and sub-pixels SP3 can be defined respectively. Sub-pixels SP3 can be used individually or in a manner that three sub-pixels SP3 constitute one optical pixel P1, but it is not limited thereto.

[0123] Taking the pattern in region R4 as an example, multiple sub-pixels SP2 and multiple sub-pixels SP3 can be arranged in multiple horizontal rows. For example, multiple sub-pixels SP2 can be arranged in two horizontal rows on the X-axis, and multiple sub-pixels SP3 can be arranged in one horizontal row on the X-axis and located between the two horizontal rows on the X-axis formed by multiple sub-pixels SP2. That is to say, in region R4, the ratio of the number of sub-pixels SP2 to that of sub-pixels SP3 can be 2:1, but is not limited to this. In region R4, through hole VA1 overlaps electrode PX of sub-pixel SP3. Through hole VA2 overlaps pixel electrode PE of sub-pixel SP2. Under the above settings, routing SL1 can extend into region R4 on the X-axis, then turn to extend to sub-pixel SP3 on the Y-axis to be electrically connected to electrode PX through through hole VA1. Routing SL2 can extend into sub-pixel SP2 on the Y-axis, then turn to extend into adjacent multiple sub-pixels SP2 on the X-axis to be electrically connected to electrode RX through through hole VA2. Under the above configuration, the touch signal can be transmitted from the bottom to the top of the electrode RX. Thus, the region R4 can have a good pixel aperture ratio. In addition, the electronic device 10F can achieve the effects of display, optical detection or touch control, but is not limited thereto.

[0124] Taking the pattern in region R5 as an example, the display pixel P2 composed of three sub-pixels SP2 and the optical pixel P1 composed of three sub-pixels SP3 can be arranged adjacent to each other and staggered. For example, the display pixel P2 can be arranged staggered with the optical pixel P1 on the X-axis and the Y-axis so that any display pixel P2 is surrounded by multiple optical pixels P1. In addition, in region R5, the ratio of the number of sub-pixels SP2 to sub-pixels SP3 can be 1:1, but is not limited to this. The ratio of the number of display pixels P2 to optical pixels P1 can be 1:1, but is not limited to this. Thereby, the transmittance of region R5 can be improved. The optical detection effect of the electronic device 10F can be improved. In addition, region R5 can have a good pixel aperture ratio, or can enable the electronic device 10F to achieve display, optical detection or touch effects, but is not limited to this.

[0125] Taking the pattern in region R6 as an example, multiple sub-pixels SP2 and multiple sub-pixels SP3 can be arranged in multiple columns. For example, the display pixel P2 composed of three sub-pixels SP2 and the optical pixel P1 composed of three sub-pixels SP3 are arranged in multiple columns on the Y axis, and the columns of display pixels P2 and the columns of optical pixels P1 can be arranged adjacent to each other on the X axis. In other words, the columns of optical pixels P1 can be located between the columns of left and right display pixels P2. In region R6, the ratio of the number of sub-pixels SP2 to sub-pixels SP3 can be 1:1, but not limited to this. The ratio of the number of display pixels P2 to optical pixels P1 can be 1:1, but not limited to this. In this way, the light transmittance of region R6 can be improved. The optical detection effect of the electronic device 10F can be improved. In addition, region R6 can have a good pixel aperture ratio, or can enable the electronic device 10F to achieve the effect of display, optical detection or touch, but not limited to this. In addition, the electronic device 10F can obtain excellent technical effects similar to the above-mentioned embodiments.

[0126] Fig. 9 This is a partial enlarged schematic diagram of the display area and the optical sensing area of ​​another embodiment of the present disclosure. For the sake of clarity and convenience of description, Fig. 9 Some components are omitted from the illustration. The electronic device 10G of this embodiment is substantially similar to Figure 8 Therefore, the same and similar components in the two embodiments are not repeated here. The difference between this embodiment and the electronic device 10F is mainly that the arrangement of the pixel electrode PE and the electrode PX of this embodiment is different.

[0127] like Fig. 9As shown, the pixel electrodes PE and the electrodes PX are arranged in a plurality of horizontal rows in an interlaced manner on the X-axis, and an optical sensing area SA2 of a horizontal row is provided between the upper and lower horizontal rows on the Y-axis. In some embodiments, the area of ​​the optical sensing area SA2 on the Z-axis may be greater than the area of ​​the optical sensing area SA or the display area DA on the Z-axis. For example, the area of ​​the optical sensing area SA2 on the Z-axis may be greater than or equal to twice the area of ​​the electrode PX or the pixel electrode PE on the Z-axis. The through hole VA1 is correspondingly located in the optical sensing area SA2 and the optical sensing area SA. In this way, the electronic device 10G can switch the display area DA to a bright state to display an image in the display mode, and switch the optical sensing area SA or the optical sensing area SA2 to a dark state. In this way, the optical signal entering the optical element 300 or the optical signal emitted by the optical element 300 can be reduced. In addition, the electronic device 10G can also switch the display area DA to a dark state in the detection mode to reduce the impact on the optical element 300, and switch the optical sensing area SA or the optical sensing area SA2 to a bright state. In this way, the optical signal entering the optical element 300 or the optical signal emitted by the optical element 300 can be increased, but the present invention is not limited thereto. In some embodiments, in the display mode, the optical sensing area SA or the optical sensing area SA2 can also be switched to a bright state. Under the above-mentioned setting, the light transmittance of the electronic device 10G can be improved, or the optical detection effect of the electronic device 10G can be improved. In addition, the electronic device 10G can have a good pixel aperture ratio, or can achieve the effect of display, optical detection or touch, but the present invention is not limited thereto.

[0128] In other embodiments, the area of ​​the display area DA and the area of ​​the optical sensing area SA may be the same or different. Figure 1B and Fig. 9As shown, the area of ​​the display area DA and the area of ​​the optical sensing area SA may be substantially the same. For example, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA may be 1:1, but not limited thereto. In some embodiments, the area of ​​the display area DA may be larger than the area of ​​the optical sensing area SA. For example, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA may be 2:1, but not limited thereto. In other embodiments, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA may be between 1:1 and 350:1 (for example: 1:1<ratio≤350:1), but not limited thereto. In other embodiments, the area of ​​the display area DA may be smaller than the area of ​​the optical sensing area SA. For example, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA may be 1:2, but not limited thereto. In other embodiments, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA may be between 1:1 and 1:350 (for example: 1:1<ratio≤1:350), but not limited thereto. In other embodiments, the user can adjust the ratio of the display area DA to the optical sensing area SA as required to obtain good display quality or good optical detection effect. For example, the ratio of the area of ​​the display area DA to the area of ​​the optical sensing area SA can be 1:3. The display area DA can occupy one of the four equal parts of the sub-pixel SP1, but is not limited to this. The proportional relationship between the area of ​​the display area DA and the area of ​​the optical sensing area SA can be adjusted arbitrarily according to actual needs and is not limited. Under the above settings, the user can adjust the ratio, arrangement or shape of the display area DA and the optical sensing area SA as required to obtain good optical quality or good optical detection effect.

[0129] Fig.10 This is a partial enlarged schematic diagram of the display area and the optical sensing area of ​​another embodiment of the present disclosure. For the sake of clarity and convenience of description, Fig.10 Some components are omitted from the illustration. The electronic device 10H of this embodiment is substantially similar to Figure 8 The electronic device 10F of the present embodiment is a display pixel P2 composed of three sub-pixels SP2, and the optical pixel P1 composed of three sub-pixels SP3. Between the two horizontal rows of the plurality of sub-pixels SP3, the optical pixel P1 and the display pixel P2 can be arranged alternately on the X-axis.

[0130] That is to say, the ratio of the number of sub-pixels SP2 to sub-pixels SP3 of the electronic device 10H may be 1:5, but is not limited thereto. The ratio of the number of display pixels P2 to optical pixels P1 may be 1:5, but is not limited thereto. In this way, the light transmittance of the electronic device 10H can be improved, or the optical detection effect of the electronic device 10H can be improved. In addition, the electronic device 10H may have a good pixel aperture ratio. The present disclosure takes the example of three sub-pixels SP3 constituting one optical pixel P1, but in other embodiments, one optical pixel P1 may be constituted by at least one sub-pixel SP3, and the size, shape, and arrangement of the sub-pixel SP3 are not limited, and the size, shape, and arrangement of the optical pixel P1 are not limited, and can be adjusted arbitrarily depending on the actual application.

[0131] In addition, in the present embodiment, the through hole VA2 may be located in the sub-pixel SP3 or the electrode PX. Under the above configuration, the line SL2 extends into the sub-pixel SP3 on the Y axis, and then turns to extend into a plurality of adjacent sub-pixels SP3 on the X axis to be electrically connected to the electrode RX through the through hole VA2. Under the above configuration, the touch signal may be transmitted from the bottom to the top of the electrode RX. In this way, the electronic device 10H may achieve the effects of display, optical detection or touch, but is not limited thereto. In addition, the electronic device 10H may obtain excellent technical effects similar to those of the above embodiments.

[0132] In summary, in the electronic device of the disclosed embodiment, since the optical element overlaps the optical element area, and the optical element area includes a display area and an optical sensing area, the electronic device can switch the display area to a bright state to display an image in the display mode, and switch the optical sensing area to a dark state or a bright state. In addition, the electronic device can also switch the display area to a dark state or a bright state in the detection mode to reduce the impact on the optical element, and switch the optical sensing area to a bright state. Thereby, the optical signal entering the optical element can be increased or the optical signal emitted by the optical element can be increased. Therefore, the electronic device can have an application of good display or good optical detection. In addition, since the wiring extends into the optical element area to drive the electrode in the optical sensing area, and another wiring drives the electrode in the touch area outside the optical element area, the other wiring outside the optical element area is less likely to affect the wiring setting in the optical element area, and the pixel opening rate in the optical element area can be improved. The wiring and another wiring can be set on the same layer, so the process can be simplified or the manufacturing cost can be reduced. In addition, the user can adjust the ratio of the number of display areas and optical sensing areas or adjust the number, density or position of the wirings according to the needs to obtain good optical quality or good optical detection effect. The electronic device of this embodiment can achieve good display, optical detection or touch effect.
