Embodiment Construction

[0020] specific implementation plan

[0021] Referring to the accompanying drawings, specific embodiments of the present invention will be described in detail below.

[0022] figure 1 It is a schematic cross-sectional view of the structure of the blue-phase liquid crystal display with controllable viewing angle of the present invention. Such as figure 1 As shown, the blue-phase liquid crystal display with controllable viewing angle of the present invention comprises: an upper substrate 10, a liquid crystal layer 30 and a lower substrate 20; the upper substrate 10 and the lower substrate 20 are arranged parallel to each other and each pixel is divided into a main pixel and a sub-pixel respectively The main pixel and the sub-pixel have the same liquid crystal box thickness, and the liquid crystal layer 30 of the main pixel and the sub-pixel all uses the same blue phase liquid crystal material; the upper substrate 10 includes an upper substrate glass layer 11, and the upper sub...

Abstract

The invention provides a viewing angle controllable blue phase liquid crystal display comprising an upper substrate, a liquid crystal layer and a lower substrate. The upper substrate and the lower substrate are parallel to each other and respectively consist of main pixels and sub-pixels; the main pixels and sub-pixels are made of the same blue phase liquid crystal material; transparent strip pixel electrodes and transparent strip public electrodes are arranged at intervals on the lower substrate; the transparent strip electrodes of the upper substrate are arranged in the range of the sub-pixels of the upper substrate; the conversion between a narrow viewing angle mode and a wide viewing angle mode is achieved by selecting whether to apply an offset voltage to the electrodes of the upper substrate. The viewing angle controllable blue phase liquid crystal display has a good viewing angle control effect, high transmission rate and a simple manufacturing process and is simple and convenient to operate.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a blue phase liquid crystal display capable of controlling the viewing angle. Background technique [0002] Liquid crystal displays have gradually replaced cathode ray tube displays and are widely used as display devices for electronic products due to their lightness, thinness, low power consumption, and no radiation. But LCDs have a narrower viewing angle than CRT displays. In order to increase the viewing angle of liquid crystal displays, technologies such as patterned vertical alignment (PVA) mode, multi-chip vertical alignment (MVA) mode, in-plane switching (IPS) mode, and fringe field switching (FFS) mode have been proposed one after another, and liquid crystal displays have been realized. wide viewing angle display. [0003] At present, more and more portable electronic devices using liquid crystal displays such as mobile phones, palmtop computers, and notebook computer...
