Abstract

The embodiment of the invention discloses a transflective liquid crystal display, belonging to the field of manufacturing of liquid crystal display. The transflective liquid crystal display comprises blue phase liquid crystal layers which are oppositely arranged, are divided into an upper substrate and a lower substrate and are filled between the upper substrate and the lower substrate; the thicknesses of liquid crystal boxes in a transmission region and in a reflection region are equal, and wall-shaped electrodes with the same structure and equal intervals are arranged in the transmission region and the reflection region; and voltage difference UT between the wall-shaped electrode and an adjacent wall-shaped electrode in the transmission region and voltage difference UF between the wall-shaped electrode and an adjacent wall-shaped electrode in the reflection region can meet the condition UT=sqrt(2)UF. According to the invention, electro-optic characteristics of the transmission region and the reflection region can be guaranteed to be matched, thus liquid crystal response times of the transmission region and the reflection region are the same, manufacturing difficulty of a display is reduced, and better viewing angle can be realized. The embodiment of the invention is applicable to manufacturing of the liquid crystal display.

Description

technical field [0001] The invention relates to the field of transflective liquid crystal display manufacturing, in particular to a single-cell thick transflective liquid crystal display. Background technique [0002] Transflective liquid crystal displays have both the excellent reading performance of reflective displays under outdoor sunlight and the excellent reading performance of fully transparent displays under backlighting in dark and low light environments, so they are widely used in aircraft display instruments, vehicle displays, and high-end mobile phones , portable computers and other fields. [0003] The sub-pixels of a transflective liquid crystal display are composed of a transmissive area and a reflective area. The transmissive area uses a backlight to emit light, and the light only passes through the liquid crystal layer once; while the reflective area relies on reflecting the surrounding light source to emit light, and the light needs to pass through the liqu...
