Problems solved by technology

[0006] Although reflective TFT LCD has greatly improved energy saving compared with traditional projective TFT LCD, due to the limitation of the principle, the light utilization rate (or pass rate) of reflective TFT LCD using the above principle is only about 10%. and low contrast
The display effect can not meet the needs, especially in the environment with relatively weak light, it is basically unusable

Embodiment 1

[0057] The concrete structure of an embodiment of the present invention is as figure 1 , figure 2 shown. In the embodiment, the main structure of the present invention has two layers of substrates: the upper substrate includes an upper insulating substrate 1; an upper light absorbing layer 2 is formed on the upper insulating substrate 1; a hexagonal upper reflective electrode The layer 3 is formed on the upper light absorbing layer 2, and the upper reflective electrode layers 3 are laterally connected by connecting wires.

[0058] The lower substrate includes a lower insulating substrate 9; gate lines and data lines formed on the lower insulating substrate 9, adjacent gate lines and data lines intersect to define a pixel area, each pixel area includes a thin film transistor 6; the cross section is positive The hexagonal concentric corrugated resin layer 7 covers the entire thin film transistor 6; the hexagonal lower reflective electrode layer 5 is formed on the resin layer ...

Embodiment 2

[0074] The specific structure of another embodiment of the present invention also includes: an upper substrate and a lower substrate, the liquid crystal layer is encapsulated between the upper substrate and the upper substrate, and the characteristics of the upper substrate are the same as those in Embodiment 1. The difference between this embodiment and embodiment 1 lies in the lower substrate, the specific structure of the lower substrate is as follows Figure 20 as shown in Figure 20As shown, the lower substrate includes: a lower insulating substrate; gate lines and data lines formed on the lower insulating substrate; adjacent gate lines and data lines intersect to define a pixel area, and each pixel area includes a thin film transistor; a section is A wavy hexagonal resin layer covering the entire thin film transistor device; these parts are the same as those in Embodiment 1, the difference being that: the lower light absorbing layer 8 is formed above the thin film transi...

Abstract

The disclosed TFT LCD includes following parts and structure: an up base plate and a low base plate, the up base plate including an up insulation substrate; an up light absorption layer; a hexagonal up reflection electrode layers connected through connecting wire in transverse direction; low base plate including a low insulation substrate; a grid line and data line; adjacent and crossed grid line and data line defines a pixel area, and each pixel area includes a TFT; a hexagonal resin layer covers entire TFT; a hexagonal low reflection electrode layer is formed on resin layer, and through a connection hole on the resin layer, the low reflection electrode layer is connected to drain electrode of TFT; low light absorption layer spaces out two adjacent pixel electrodes. Giving full play to advantages of LCD, the invention makes use ratio of reflected light near to 100%, and possesses very low energy consumption.

Description

technical field [0001] The invention relates to a TFT LCD (thin film transistor liquid crystal display) and a manufacturing method thereof, in particular to a reflective TFT LCD based on the principle of total reflection and a manufacturing method thereof. Background technique [0002] Due to the continuous improvement of people's requirements for various performances of display devices (such as color, response speed, size, etc.), and continuous technological progress, flat-panel displays such as TFT LCD, PDP, OLED, etc. have been developed rapidly. Especially for TFT LCD, due to the efforts of South Korea, Taiwan and other manufacturers, TFT LCD has become the flat panel display device with the highest market share. [0003] TFT LCD utilizes the modulation effect of liquid crystal on polarized light to control the intensity of light passing through the pixels, so as to realize the screen display. Due to the limitation of the principle, ordinary TFT LCD needs a backlight so...
