Semi-transmitting half-reflection liquid crystal display and manufacturing method thereof

Abstract

The invention provides a semi-transmitting half-reflection liquid crystal display and a manufacturing method thereof. The semi-transmitting half-reflection liquid crystal display comprises a plurality of pixels, wherein each pixel comprises a transmission region and a reflection region which are adjacent to each other and have the same box thickness; each pixel also comprises a first transparent electrode arranged between a liquid crystal layer and an array substrate; the transmission region of each pixel comprises a second transparent electrode arranged between the liquid crystal layer and a color film substrate; a voltage difference is formed between a first voltage applied by the first transparent electrode and a second voltage applied by the second transparent electrode; due to the voltage difference, an initial optical delay of the liquid crystal layer positioned in each transmission region is one second of wavelength; in each pixel, an initial optical delay of the liquid crystal layer positioned in the reflection region is three fourths of wavelength, so that the transmission region and the reflection region of each pixel have different optical delays; and due to the adoption of the design of equal box thicknesses of the transmission regions and the reflection regions, the manufacturing process is simple.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a semi-transmissive and semi-reflective liquid crystal display and a manufacturing method thereof Background technique [0002] A liquid crystal display can be composed of components such as a display screen, a backlight source, and a driving circuit. Specifically, the display screen may include an array substrate, a color filter substrate, and a liquid crystal layer that are boxed together, and the liquid crystal layer fills the gap between the array substrate and the color filter substrate. The principle of displaying images on a liquid crystal display can be based on the fact that when the liquid crystal molecules in the liquid crystal layer rotate with the pressure applied by the drive circuit, the alignment direction of the liquid crystal molecules also changes, resulting in a change in the light that penetrates the liquid crystal molecules. characteristic. ...

Problems solved by technology

[0006] However, the above-mentioned prior art solution is technically difficult to implement, which increases the difficulty of the production process of the transflective liquid crystal display, and also increases the production cost of the transflective liquid crystal display. In semi-reflective liquid crystal displays, the scheme of consistent optical delay in the transmissive area and reflective area of ​​the display screen is very low in feasibility.
