In addition to supplementing the power of electronic products by carrying a mobile power supply, charging electronic products by solar energy is also one of the emerging charging methods.

[0003] In order to reduce the overall thickness of the display panel with the solar cell, a display panel with a common conduction design can be used. In order to make the conductive path of the solar cell directly transmit from the bus line on the color filter layer side to the flexible printed circuit board on the color filter layer side, so as to effectively avoid the attenuation of the electrical properties of the solar cell in transmission, a double bonding architecture can be used. However, based on the consideration of display function and photoelectric conversion function, the first organic layer located in the left and right frame areas of the display panel needs to be provided with a through opening for wiring connection of the solar cell, and the common electrode layer on the color filter layer side needs to be provided with a second organic layer to isolate the solar cell, so that the gap of the left and right frame areas of the display panel is larger than that of the upper and lower frame areas, resulting in the existing display panel having the problem of uneven display effect (mura).

[0004] Therefore, how to propose a display panel that can solve the problem of uneven display effect is one of the problems to be solved in the art. UTILITY MODEL CONTENT

The display panel includes: an array substrate, a frame adhesive layer, and an optical substrate; the frame adhesive layer is arranged on the array substrate and corresponds to the non-display area, and the frame adhesive layer is electrically connected with the array substrate. The optical substrate is arranged on the frame adhesive layer and includes: a solar energy conversion layer, a first organic layer, an electrode conductive layer, a second organic layer, and a common electrode layer; the solar energy conversion layer is arranged in the non-display area; the first organic layer covers the solar energy conversion layer and is provided with an annular opening, the annular opening corresponds to the frame adhesive layer, and the annular opening exposes part of the solar energy conversion layer in the non-display area; the electrode conductive layer is arranged on the first organic layer and includes a negative electrode conductive layer and a positive electrode conductive layer; the negative electrode conductive layer is electrically connected with the solar energy conversion layer located in the first frame area, the second frame area, and the third frame area and exposed by the first organic layer; the positive electrode conductive layer is electrically connected with the solar energy conversion layer located in the fourth frame area and exposed by the first organic layer; the second organic layer is arranged on the electrode conductive layer; and the common electrode layer is arranged on the second organic layer and is electrically connected with the frame adhesive layer.

[0007] Based on the above content, the display panel of the present application embodiment, by virtue of the annular opening of the first organic layer corresponding to the frame adhesive layer, the electrical connection of the negative electrode conductive layer with the solar energy conversion layer located in the first frame area, the second frame area, and the third frame area and exposed by the first organic layer, and the electrical connection of the positive electrode conductive layer with the solar energy conversion layer located in the fourth frame area and exposed by the first organic layer, the frame adhesive layer of the display panel has the same / approximate width and height in the first frame area, the second frame area, the third frame area, and the fourth frame area; by virtue of the configuration of the second organic layer to insulate the solar energy conversion layer with photoelectric conversion capability and the common electrode layer, the electrical property of the solar energy conversion layer and the pixel can be avoided from being affected (i.e., the solar energy conversion layer can normally operate); thus, the endurance of the electronic product applying the display panel of the present application embodiment can be increased, and the optical property of the display panel (i.e., the display area of the display panel has a uniform display effect) can be maintained.

[0026] The frame adhesive layer 140 is disposed on the array substrate 130 and corresponds to the wiring areas 123a of the first frame area 121, the second frame area 122, the third frame area 123, and the wiring areas 124a of the fourth frame area 124 (i.e., the frame adhesive layer 140 is disposed corresponding to the non-display area 120), and the frame adhesive layer 140 is electrically connected to the array substrate 130.

[0027] The optical substrate 200 is disposed on the frame adhesive layer 140 and includes a solar energy conversion layer 210, a first organic layer 220, an electrode conductive layer 230, a second organic layer 240, and a common electrode layer 250, which are stacked in the third direction (i.e., the Z-axis direction, which is perpendicular to the X-axis direction and the Y-axis direction). In addition, the optical substrate 200 can further include a second substrate 260, which covers the solar energy conversion layer 210 to protect the solar energy conversion layer 210. The second substrate 260 can be a transparent substrate such as glass or plastic, but is not limited thereto.

[0028] The solar energy conversion layer 210 is disposed in the non-display area 120. The solar energy conversion layer 210 can include, in sequence, a positive electrode layer 211, a photoelectric conversion layer 212, and a negative electrode layer 213 stacked on the second substrate 260. The solar energy conversion layer 210 in the photoelectric conversion area 123b of the first, second, and third frame areas 121, 122, and 123 and the photoelectric conversion area 124b of the fourth frame area 124 can define a solar cell unit and have a photoelectric conversion function. The solar energy conversion layer 210 in the wiring area 123a of the third frame area 123 does not have a photoelectric conversion function and only serves as a negative electrode wiring layer 50. The solar energy conversion layer 210 in the wiring area 124a of the fourth frame area 124 does not have a photoelectric conversion function and only serves as a positive electrode wiring layer 60. The negative electrode wiring layer 50 and the positive electrode wiring layer 60 are photoelectric transmission wiring layers.

[0029] The first organic layer 220 covers the solar energy conversion layer 210 and is provided with an annular opening 222 corresponding to the frame adhesive layer 140, which exposes part of the solar energy conversion layer 210 in the non-display area 120. Specifically, the annular opening 222 penetrates the first organic layer 220 and exposes the negative electrode layer 213 of the solar energy conversion layer 210 in the first and second frame areas 121 and 122, the negative trace layer 50 in the trace area 123a of the third frame area 123, and the positive trace layer 60 in the trace area 124a of the fourth frame area 124. Therefore, the first organic layer 220 corresponding to the frame adhesive layer 140 has the same structural design in the first, second, third, and fourth frame areas 121, 122, 123, and 124 (e.g. Figure 4 As shown in Figure 5 , Figure 4 As shown in Figure 2 , Figure 3 the top view of the optical substrate of the display panel 100, Figure 5 As shown in Figure 4 , an embodiment schematic diagram of the CC' cross-sectional line of the display panel 100); It should be noted that the optical substrate 200 of the display panel 100 is independently manufactured and then arranged on the frame adhesive layer 140. The optical substrate 200 is prepared by sequentially stacking the solar energy conversion layer 210, the first organic layer 220, the electrode conductive layer 230, the second organic layer 240, and the common electrode layer 250 on the second substrate 260. In an embodiment, the outer edge of the first organic layer 220 protrudes from the outer edge of the frame adhesive layer 140, and the distance between the outer edge of the first organic layer 220 and the outer edge of the frame adhesive layer 140 can be 10-30 microns. In addition, the edge of the display panel 100 is covered by the first organic layer 220, which covers the solar energy conversion layer 210, which can avoid the problem of reliability caused by the exposure of the solar energy conversion layer 210.

The negative electrode conductive layer 231 is electrically connected to the solar energy conversion layer 210 located in the first, second, and third frame areas 121, 122, and 123 and exposed by the first organic layer 220. The positive electrode conductive layer 232 is electrically connected to the solar energy conversion layer 210 located in the fourth frame area 124 and exposed by the first organic layer 220. Specifically, the negative electrode conductive layer 231 is disposed on the portion of the first organic layer 220 and the annular opening 222 in the first, second, and third frame areas 121, 122, and 123 to be electrically connected to the negative electrode layer 213 and the negative electrode trace layer 50 exposed by the first organic layer 220. The positive electrode conductive layer 232 is disposed on the portion of the first organic layer 220 and the annular opening 222 in the fourth frame area 124 to be electrically connected to the positive electrode trace layer 60 exposed by the first organic layer 220. Therefore, by disposing the negative electrode conductive layer 231 and the positive electrode conductive layer 232, the first, second, third, and fourth frame areas 121, 122, 123, and 124 corresponding to the frame adhesive layer 140 have the same structural design. The negative electrode conductive layer 231 and the positive electrode conductive layer 232 can be metal conductive layers, and the materials of the negative electrode layer 213 and the positive electrode layer 232 can include, but are not limited to, aluminum, copper, gold, chromium, tantalum, titanium, manganese, nickel, molybdenum, niobium, neodymium, silver, or a combination thereof.

[0031] The second organic layer 240 is disposed on the electrode conductive layer 230. Specifically, the second organic layer 240 covers the electrode conductive layer 230 and the first organic layer 220 not covered by the electrode conductive layer 230 to insulate the electrical properties of the solar energy conversion layer 210 and maintain the electrical properties of the solar energy conversion layer 210 on the side of the color filter layer. The common electrode layer 250 is disposed on the second organic layer 240 and electrically connected to the frame adhesive layer 140. The common electrode layer 250 can be electrically connected to an external circuit through the wiring 13, for example, the common electrode layer 250 can be electrically connected to the flexible circuit board 14 through the wiring 13 (as shown in FIG. 1B). Figure 1

[0032] In this embodiment, by the design of the first organic layer 220, the negative electrode conductive layer 231, and the positive electrode conductive layer 232, the frame adhesive layer 140 of the display panel 100 has the same / approximate width and height in the first, second, third, and fourth frame areas 121, 122, 123, and 124. By the design of the second organic layer 240, the electrical properties of the solar energy conversion layer 210 and the common electrode layer 250 are isolated, and the solar energy conversion layer 210 can normally operate. Therefore, while increasing the endurance of the electronic product applying the display panel 100, the optical properties of the display panel 100 (i.e., the display area 110 of the display panel 100 has a uniform display effect) can also be maintained. ​

In addition, the negative conductive layer 231 can be divided into the first negative bus 31, the second negative bus 32, the ramp area 33 and the conversion area 34.

[0034] In an embodiment, referring to Figure 2 , Figure 3 As shown in Figure 6 , the solar conversion layer 210 is provided with an annular groove 214 close to the display area 110, the annular groove 214 surrounds the display area 110 and exposes the positive electrode layer 211 of the solar conversion layer 210; the first organic layer 220 is also provided with an annular opening 224 penetrating the first organic layer 220 and corresponding to the annular groove 214; the positive conductive layer 232 can also be arranged on the annular groove 214, the annular opening 224 and part of the first organic layer 220 in the fourth bezel area 124 to be electrically connected with the positive electrode layer 211 exposed by the annular groove 214. Since the positive conductive layer 232 can be arranged on the annular groove 214 and the annular opening 224, part of the top view shape of the positive conductive layer 232 is in the shape of a mouth (as shown in Figure 6 As shown in , the positive conductive layer 232 can be divided into the positive bus 41, the ramp area 42 and the conversion area 43, and the top view shape of the conversion area 43 is in the shape of a mouth.

The height of the frame adhesive layer 140 in different frame regions can be used to determine the particle size of the conductive particles 142; when the heights of the frame adhesive layers 140 in different frame regions are different, only the conductive particles 142 with the particle size corresponding to the lowest height can be selected, but there is a problem of insufficient supporting force. In the present application, the heights of the frame adhesive layers 140 in different frame regions are the same / similar, so the conductive particles 142 can abut the common electrode layer 250 and the electrode layer 135, and there is no problem of insufficient supporting force.

[0038] In an embodiment, the width W1, the width W2, the width W3, and the width W4 are the same, and the width of the frame adhesive layer 140 (i.e., the width W1, the width W2, the width W3, or the width W4) can be, but is not limited to, 600 microns to 1200 microns.
