Abstract

The invention discloses a transflective blue-phase LCD (Liquid Crystal Display) comprising an upper substrate, a liquid crystal layer and a lower substrate. The upper substrate and the lower substrate are arranged in parallel and respectively divided into a transmission area and a reflection area which are made the same blue-phase liquid crystal material; a transmission plane internal conversion electrode is formed by alternately arranging pixel electrodes and common electrodes; an etching area in the same depth is etched from the part between two adjacent transmission plane internal conversion electrodes of the transmission area to the inside of the glass layer of the lower substrate, and the reflection layer of the reflection area is arranged in the lower substrate; and the transmission area electrode generates an electric field in a double penetration depth so that the blue-phase liquid crystal arranged in the etching area contributes to the accumulation of phase delay to not only reduce the working voltage of a liquid crystal box, but also realize the phase delay match between the transmission area and the reflection area. The transmission area and the reflection area provided by the invention have the same liquid crystal box thickness, and the transmission plane internal conversion electrode and the electrode gap in the same size are adopted, thus the manufacture difficulty is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a transflective blue phase liquid crystal display. Background technique [0002] The emergence of thin-film transistor (TFT) driving technology has greatly improved the brightness, contrast, layering, and color display of liquid crystal displays. In order to solve the narrow viewing angle problem of liquid crystal display, in-plane switching (IPS) mode, fringe field switching (FFS) mode, multi-domain vertical alignment (MVA) mode, patterned vertical alignment (PVA) mode and other wide viewing angle technologies have been proposed one after another. However, the response speed has always been the weak point of LCD. In recent years, with the development of color sequential display technology, more and more liquid crystal displays have begun to use red, green and blue tricolor light-emitting diodes (RGB-LED) as backlight sources. Liquid crystal displays using color sequentia...
