Single cell-gap transflective blue phase liquid crystal display (LCD) with matched transflective electro-optical characteristic curves

Abstract

The invention discloses a single cell-gap transflective blue phase LCD with matched transflective electro-optical characteristic curves. The single cell-gap transflective blue phase LCD is characterized in that the transmissive region and the reflective region of the LCD have an identical cell thickness; an upper substrate includes a glass layer, a quarter-wave plate, a half-wave plate and a polarizer; a lower substrate includes a glass layer, a quarter-wave plate, half-wave plate and a polarizer; and the reflective layer of the reflective region is arranged in the lower glass substrate. Bump electrodes of the reflective region are only arranged on the glass layer of the lower substrate; bump electrodes of the transmissive region are arranged below the glass layer of the upper substrate and on the glass layer of the lower substrate; the bump electrode consists of pixel electrodes and common electrodes arranged alternately at intervals; the bump electrodes are identical in the size, and adjacent two bump electrodes have an identical gap; and the transflective electro-optical characteristic curves can be matched with each other by adjusting the thickness of the liquid crystal cell. In addition, the single cell-gap transflective blue phase LCD has low work voltage and wide visual angle.

Description

technical field [0001] The invention relates to the field of liquid crystal display, more specifically, the invention relates to the field of transflective liquid crystal display, especially the transflective liquid crystal display using blue phase liquid crystal. Background technique [0002] Liquid crystal displays can be divided into three categories: transmissive, reflective, and transflective. The transmissive liquid crystal display adopts the backlight emitting mode and has a good display effect indoors, but it consumes a lot of power and is not suitable for outdoor use. Reflective liquid crystal displays use ambient light to save power consumption, and have good display effects especially outdoors, but they cannot be used in dark rooms. Transflective LCDs combine the advantages of both transmissive and reflective LCDs. Each sub-pixel of a transflective liquid crystal display is composed of a transmissive area and a reflective area, and the transmissive area and the ...

AI Technical Summary

Problems solved by technology

However, the manufacturing process of the double-cell thick transflective liquid crystal display panel is complicated, and the response time of the transmissive area and the reflective area is not equal due to the difference in the thickness of the liquid crystal cell.
