Problems solved by technology

[0005] However, the existing transflective blue-phase liquid crystal display generally adopts a double-cell thick structure to ensure that the optical path difference between the transmissive area and the reflective area is consistent, and there are two major technical problems, high driving voltage and low light efficiency.

Embodiment Construction

[0019] The blue-phase liquid crystal panel in the prior art is driven by a horizontal electric field, and the driving voltage of this blue-phase liquid crystal panel is relatively high. Since the electric field lines of the vertical electric field (that is, the electric field perpendicular to the substrate) are more uniform, it is beneficial to reduce the driving voltage of the blue-phase liquid crystal panel, so the present invention provides a blue-phase liquid crystal panel driven by the vertical electric field.

[0020] Firstly, the characteristics of the blue phase liquid crystal molecules are briefly introduced. When no voltage is applied, the blue-phase liquid crystal molecules have isotropic properties; when a voltage is applied, the blue-phase liquid crystal molecules have birefringence properties along one direction, and the blue-phase liquid crystal molecules are aligned along the direction of the electric field.

[0021] Due to the above-mentioned characteristics o...

Abstract

A blue-phase liquid crystal panel and a display device can be used to decrease the driving voltage of the blue-phase liquid crystal panel and improve the optical efficiency. The blue-phase liquid crystal panel comprises: a first prism layer (101) located between a blue-phase liquid crystal layer (003) and a first polarizer (004), a second prism layer (102) located between the blue-phase liquid crystal layer (003) and a second polarizer (005), a common electrode (008) located on an inner side of a second substrate (002), a gate line (300) located on an inner side of a first substrate (001), a first data line (301), a second data line (302), and a pixel unit limited by the gate line (300), the first data line (301), and the second data line (302). Each pixel unit is divided into a transmission area and a reflection area. A first pixel electrode (006) is disposed in the transmission area, and a second pixel electrode (007) and a reflecting layer (009) are disposed in the reflection area. During electrification, the first and second data lines (301, 302) respectively apply different voltages on the first and second pixel electrodes (006, 007), and optical path differences generated by light in the transmission area and light in the reflection area that pass through the blue-phase liquid crystal layer (003) are the same.

Description

technical field [0001] The invention relates to the field of design and manufacture of a liquid crystal panel and a display device, in particular to a transflective blue-phase liquid crystal panel and a display device. Background technique [0002] According to different types of light sources used, liquid crystal display devices can be classified into three types: transmissive, reflective, and transflective. Among them, the transflective liquid crystal display device has the advantages of both the transmissive and reflective liquid crystal display devices, so it is widely used in display devices of electronic products. [0003] In order to improve the display quality of liquid crystal displays, achieve higher contrast, faster response time and wider viewing angle, blue-phase liquid crystal materials with fast response characteristics have gradually been paid attention to. The blue phase is a liquid crystal phase between the isotropic phase and the cholesteric phase, and it...
