Abstract

The invention relates to a transflective LCD, which comprises a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer between the first substrate and the second substrate, a first polaroid sheet arranged on the surface of the outside of the first substrate, a second polaroid sheet arranged on the surface of the outside of the second substrate, a common electrode layer, an insulating layer, a pixel electrode layer and a second alignment layer which are arranged on the surface of the inside of the second substrate in order, and a control electrode layer and a first alignment layer which are arranged on the surface of the inside of the first substrate, wherein the common electrode layer comprises a transmittance zone and a reflective zone; the control electrode layer is positioned in a zone corresponding to the transmittance zone, and is applied with a voltage, so that the inclination angle of liquid crystal molecules corresponding to the transmittance zone is larger than that of liquid crystal molecules corresponding to the reflective zone, and the birefringence of the liquid crystal molecules corresponding to the transmittance zone is improved. The transflective LCD does not need an internal delay chip to reduce the cost.

Description

technical field [0001] The invention relates to a transflective liquid crystal display, in particular to a fringe electric field switch type transflective liquid crystal display. Background technique [0002] Liquid crystal displays are widely used because of their low radiation, light, thin and small size, and low power consumption. With the maturity and innovation of related technologies, their types are also becoming more and more diverse. [0003] According to different light sources used, liquid crystal display devices can be divided into transmissive liquid crystal display devices and reflective liquid crystal display devices. The transmissive liquid crystal display device must set a backlight on the back of the liquid crystal display panel to realize image display, however, the energy consumption of the backlight accounts for about half of the energy consumption of the entire transmissive liquid crystal display device, so the power consumption of the transmissive liqu...
