Method for manufacturing liquid crystal display module with photovoltaic cells and liquid crystal display module prepared therefrom

Abstract

A method for manufacturing a liquid crystal display module with a photovoltaic cell (200). The method comprises: step 1: providing a substrate (20) and a liquid crystal display panel (40); step 2: forming a transparent conducting layer on the substrate (20) in a sputtering manner; step 3: arranging a first matrix (22) below a TFT array (420) away from a pixel opening of the liquid crystal display panel (40); step 4: forming a photovoltaic layer on the transparent conducting layer in a chemical vapor deposition manner; step 5: etching the photovoltaic layer into a second matrix (24) corresponding to the first matrix (22) through processes of photo-mask and dry etching; step 6: forming a metal layer on the photovoltaic layer in a sputtering manner; step 7: etching the metal layer into a third matrix (26) corresponding to the second matrix (24) through processes of photo-mask and wet etching, and further forming the photovoltaic cell (200) on the substrate (20); step 8: corresponding to the periphery of the photovoltaic cell (200), coating sealing glue (60) on the substrate (20); and step 9: oppositely attaching the substrate (20) with the liquid crystal display panel (40) and solidifying the sealing glue (60). Further provided is a liquid crystal display module manufactured by using the foregoing method.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method for manufacturing a liquid crystal display module with photovoltaic cells and the prepared liquid crystal display module. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, and control the liquid crystal molecules to change direction through whether the glass substrates are energized or not, and refract the light from the backlight module to produce a picture. Since the liquid crystal display panel itself does not emit light...

Problems solved by technology

[0006] However, the existing technology is to integrate the finished photovoltaic cells into the liquid crystal display panel, the manufacturing process is relatively complicated, and the production cycle is also long, which increases the production cost, and the photovoltaic cells are easily corroded and oxidized by external water vapor, oxygen, etc. Resulting in low service life of photovoltaic cells
