Problems solved by technology

[0005] But this kind of polarizer will also affect the transmittance of the light emitted by the OLED device of the TFT array substrate 11 while filtering the ambient light, and it is expensive
Since the light emitted by the OLED device also needs to pass through the circular polarizer 122 and the linear polarizer 121, the transmittance of the polarizer can only be 40% to 50% at present, and the brightness of the picture of the AMOLED display device is therefore reduced. Efficiency suffers greatly

Abstract

The invention discloses an AMOLED display device and a preparation method thereof. By making a chromium-containing light-shielding layer on a TFT array substrate opposite to the signal line, the signal line is electrically connected to the chromium-containing light-shielding layer through a drilling process, which can absorb light and reduce the wiring resistance; by attaching a layer of refraction film on the side of the TFT array substrate along the light-emitting direction away from the chromium-containing light-shielding layer, the reflection of ambient light can be blocked without a polarizer, and the polarizer can be removed. The purpose is to improve the luminous efficiency and screen brightness while saving costs.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an AMOLED display device and a preparation method thereof. Background technique [0002] With the rapid development of electronic technology and display technology, liquid crystal display devices (Liquid Crystal Display, LCD) have been widely used, such as: LCD TVs, smart phones, computers, tablet computers and other modern information devices. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a backplane (BackPlate, BP), a liquid crystal display panel (Panel) and a backlight unit (Back Light Unit, referred to as BLU). A liquid crystal display panel is usually composed of a color filter (CF for short) substrate, a thin film transistor (Thin Film Transistor, TFT for short) array substrate, and a liquid crystal layer (LCL for short) disposed between the two substrates. constitute. A polari...
