Problems solved by technology

[0003] Since the liquid crystal display device is not an active light-emitting device, it needs a backlight source to achieve the display effect, so the main mode of the liquid crystal display is the transmission mode, which has good readability indoors, but in the case of strong sunlight or light, due to the surface of the liquid crystal display reflected light, resulting in poor readability

Abstract

The invention provides a transmission-reflection mode blue-phase liquid crystal display which structurally comprises an upper polaroid, a second double-axis compensation film, a second -A compensation film, a second +A compensation film, an upper glass substrate, an intermediate part, a lower glass substrate, a first -A compensation film, a first +A compensation film, a first double-axis compensation film and a lower polaroid. The intermediate part is composed of blue-phase liquid crystal, a first Pixel electrode, a second Pixel electrode, an insulation layer, a reflection aluminum electrode layer and a protrusion. According to the transmission-reflection mode blue-phase liquid crystal display, an aluminum electrode layer is introduced between coplanar electrodes as a reflection layer to increase the reflection effect, the introduced aluminum reflection layer effectively divides display pixels into a transmission area and a reflection area, and through the adjustment of the sizes of the coplanar electrodes and the aluminum reflection electrode and the distance between the coplanar electrodes and the aluminum reflection electrode, the transmittance and reflectivity of electro-optical characteristic curve of the pixels are made to be consistent so that defects in the prior art can be overcome, and the outdoor readable effect of blue-phase liquid crystal is enhanced.

Description

technical field [0001] The invention designs a device in the technical field of blue-phase liquid crystal display, in particular a transflective mode blue-phase liquid crystal (BPLC) display. Background technique [0002] The blue phase liquid crystal display has the following advantages: (1) response time below milliseconds; (2) wide viewing angle and high contrast; (3) no alignment layer is required in the manufacturing process; (4) there is no need to strictly control the thickness of the liquid crystal layer restrictions, etc. These advantages make the production cost of the blue phase liquid crystal display lower, the manufacturing process is simpler, and the performance is superior. Therefore, it is considered to have the most potential to become the next generation of liquid crystal displays. [0003] Since the liquid crystal display device is not an active light-emitting device, it needs a backlight source to achieve the display effect, so the main mode of the liqu...
