Example Embodiment

[0025] Example one

[0026] The embodiment of the present invention provides an array substrate, such as figure 1 with figure 2 As shown, the array substrate includes a plurality of light-transmitting areas 2 and a light-shielding area 1 surrounding each light-transmitting area 2. The light-shielding area 1 includes a first electrode 11, a photoelectric conversion film 12, and a second electrode 13 which are sequentially stacked. , The first electrode 11, the photoelectric conversion film 12 and the second electrode 13 constitute a photoelectric conversion unit, wherein the first electrode 11 is a transparent electrode.

[0027] It should be noted that the photoelectric conversion film 12 includes an N-type semiconductor film and a P-type semiconductor film. The N-type semiconductor film and the P-type semiconductor film form a PN junction; in addition, the photoelectric conversion film 12 may also include an N-type semiconductor film and a P-type semiconductor film. The I-type se...

Example Embodiment

[0043] Example two

[0044] The embodiment of the present invention provides a method for manufacturing an array substrate. The array substrate includes a plurality of light-transmitting areas, and a light-shielding area surrounding each light-transmitting area, such as image 3 As shown, the method includes:

[0045] In step S301, a first electrode layer is formed, and a pattern including the first electrode is formed on the shading area through a patterning process. Exemplarily, a first electrode layer is formed by plasma-enhanced chemical vapor deposition, sputtering, or thermal evaporation, and a photoresist is coated on the first electrode layer, and a mask with a pattern of the first electrode is used to cover After the first electrode layer coated with photoresist is exposed, developed, and etched, a pattern including the first electrode is formed on the shading area.

[0046] Step S302, forming a photoelectric conversion film layer, and forming a pattern including the photo...

Abstract

The invention discloses an array substrate and a production method thereof, as well as a display device, and relates to the technical field of display. According to the array substrate and the production method thereof, as well as the display device, light-proof areas are effectively utilized. The array substrate comprises a plurality of light-transmitting areas, and light-proof areas surrounding the light-transmitting areas; each light-proof area comprises a first electrode, a photoelectric conversion film and a second electrode which are overlapped sequentially and form a photovoltaic conversion unit, and each first electrode is a transparent electrode. The array substrate provided by the invention can be applied to the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] The display device includes a plurality of light-transmitting regions, and a light-shielding region surrounding each light-transmitting region, wherein the light-shielding region includes a black matrix, which can prevent the light emitted from the backlight from leaking from the light-shielding region, so as to ensure the light-shielding region The screen is displayed normally. [0003] However, the inventors of the present application found that the black matrix can only be used to prevent the light emitted from the backlight from leaking from the light-shielding area, but has no other function, which makes the light-shielding area unable to be effectively used. Moreover, as the resolution of the display device increases gradually, the area of ​​the light-shielding ...
