An insulating space is provided between any two adjacent photoelectric conversion units 112, that is, an insulating space is provided between any two adjacent photoelectric conversion units 112, so that an electrical connection between two adjacent photoelectric conversion units 112 is avoided.

In one embodiment, as shown in fig. 5, the number of the first electrode lines 122 is at least 2; the number of the second electrode lines 132 is at least 2;
each photoelectric conversion unit 112 is electrically connected to any one of the first electrode lines 122; each photoelectric conversion unit 112 is electrically connected to any one of the second electrode lines 132.
Specifically, the number of the first electrode lines 122 may be at least 2, and the number of the second electrode lines 132 may be at least 2. Each photoelectric conversion unit 112 in the photoelectric conversion layer 110 is electrically connected to any one of the first electrode lines 122 and any one of the second electrode lines 132, so that any one photoelectric conversion unit 112 can output through the first electrode line 122 and the second electrode line 132 connected thereto.

Further, the electrical signal may be a voltage signal, a current signal, and/or an electromagnetic field signal.
The control circuit may be configured to analyze the touch operation to obtain a control signal corresponding to the touch operation, so that the photoelectric conversion apparatus 10 may sequentially implement touch detection and multi-touch detection. According to the touch control method and device, the change of the output of each unit light conversion unit to the electric signal is detected, so that the touch position and the gesture can be detected, and the output of a touch control instruction is realized.

the first cover plate 210 is a cover plate glass with a thickness selected from 0.01 mm to 0.2 mm, the second cover plate 220 is a cover plate glass with a thickness selected from 0.01 mm to 0.2 mm, the adhesive layer is an OCA or an OCR with a thickness selected from 0.001 mm to 0.2 mm, the touch layer is a flexible transparent light-sensing touch sheet with a thickness selected from 0.01 mm to 0.2 mm, and the display layer is a flexible OLED (organic light-Emitting Diode) screen. The display panel in this example can obtain a flexible structural characteristic, and further, as the thicknesses of the first cover plate 210, the second cover plate 220, the laminating layer and the touch layer are reduced and the flexibility is increased, the display panel can meet the requirements of curling, flexibility and light sensation touch by matching with corresponding frame materials.
Adopt ultra-thin cover plate glass, with the combination of flexible touch-control display module assembly, cooperation flexible frame design (or 3 design that do not have the frame) for display panel can realize collapsible, flexible structural feature that can curl. The glass can be transparent flexible materials such as inorganic glass, organic resin glass, PET film materials and the like.
Example two:
the first cover plate 210 is a cover plate glass with a thickness selected from 0.1 mm to 3 mm, the second cover plate 220 is a cover plate glass with a thickness selected from 0.1 mm to 3 mm, the adhesive layer is an OCA or an OCR with a thickness selected from 0.001 mm to 0.2 mm, and the touch layer is a transparent photoelectric conversion device 10 with a light touch function with a thickness selected from 0.01 mm to 1 mm, and is combined with the display screen. The display panel in this example can obtain the structural characteristic that has certain structural strength, and along with the increase in thickness of first apron 210, second apron 220, laminating layer and touch-control layer, structural strength increases, cooperates corresponding frame material for display panel can satisfy the light application of ordinary consumer electronics product.
Example three:
the first cover plate 210 is cover plate glass with a thickness selected from 3 mm to 20 mm, the second cover plate 220 is cover plate glass with a thickness selected from 3 mm to 20 mm, the adhesive layer is OCA or OCR with a thickness selected from 0.001 mm to 8 mm, the touch layer is a transparent photoelectric conversion device 10 with a light touch function with a thickness selected from 0.01 mm to 3 mm, and the display panel in this example can realize structural characteristics with architectural structural strength, and as the thicknesses of the first cover plate 210, the second cover plate 220, the adhesive layer and the touch layer increase, the structural strength increases, and the display panel can meet the structural function requirements of an oversized building by matching with corresponding frame materials.
When the display screen is a transparent display screen, the first cover plate 210 and the second cover plate 220 are both made of transparent cover plate glass, and the touch layer is the transparent photoelectric conversion device 10, the display panel can realize a transparent touch display function, and can realize simple and cool product design. Further, when the first cover plate 210 and the second cover plate 220 are made of thick cover plate glass, the first cover plate and the second cover plate are combined with a touch display module, and a high-strength frame design is matched to form high structural strength, so that the display panel can be used for realizing the functions of a wall body and a partition. The cover glass can be made of transparent materials such as inorganic glass, organic resin glass and the like.
