Problems solved by technology

However, this technology requires liquid crystal displays to have a faster response speed, and the corresponding speed of most common nematic liquid crystal displays is 10ms, which cannot meet the requirements of color sequential display.

Abstract

The invention provides a blue phase liquid crystal display device capable of achieving a visual angle controllable characteristic and a transflective characteristic. The device sequentially comprises an upper Polaroid, an upper lambda / 4 double-shaft film, an upper lambda / 2 negative A piece, an upper lambda / 4 positive A piece, an upper substrate, an upper substrate IPS electrode, blue phase crystals, a lower substrate IPS electrode, a lower substrate, a lower lambda / 4 negative A piece, a lower lambda / 2 positive A piece, a lower lambda / 4 double-shaft film and a lower Polaroid from top to bottom, wherein the upper substrate IPS electrode is an ITO electrode which comprises an upper substrate Pixel electrode and an upper substrate Common electrode, and the lower substrate IPS electrode is an aluminum electrode which comprises a lower substrate Pixel electrode and a lower substrate Common electrode. The box thickness of a transflective area is the same as the box thickness of a reflecting area, manufacturing difficulties are greatly reduced, meanwhile, the transflective area and the reflecting area have the same phase delay, driving can be conducted through a single gamma curve, driving difficulties are reduced, and meanwhile dual display characteristics, namely, the visual angle controllable characteristic and the transflective characteristic, are achieved.

Description

technical field [0001] The invention designs a device in the technical field of liquid crystal display, specifically a blue-phase liquid crystal display device capable of realizing transflective display and display with controllable viewing angle. Background technique [0002] Transflective liquid crystal displays are widely used in mobile display devices due to their features such as sunlight readability and low power consumption. In order to meet the readability in sunlight, single-cell thick liquid crystal displays and double-cell thick liquid crystal displays have been proposed, and the former is more favored by manufacturers because of its simple manufacturing process. However, it is more difficult for a single-cell thick liquid crystal display to achieve phase delay matching between the transmissive area and the reflective area, because the backlight source passes through the transmissive area once, while the ambient light passes through the reflective area twice. At ...
