Abstract

The invention provides a blue-phase liquid crystal display, a blue-phase liquid crystal display module and a manufacture method thereof. The blue-phase liquid crystal display module comprises an upper substrate, a lower substrate and blue phase liquid crystals, wherein the upper substrate and the lower substrate are oppositely arranged; the blue phase liquid crystals are arranged between the upper substrate and the lower substrate; pixel electrodes and common electrodes are arranged on the lower substrate alternately at intervals; electric fields are formed between the pixel electrodes and common electrodes to drive the blue phase liquid crystals. The blue-phase liquid crystal display module can form multiple IPS electric fields, so that the driving voltage of the blue phase liquid crystals is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a blue-phase liquid crystal display module, a blue-phase liquid crystal display and a manufacturing method thereof. Background technique [0002] Compared with the currently widely used liquid crystal materials for liquid crystal display, the blue phase liquid crystal has the following four outstanding advantages: (1) The response time of the blue phase liquid crystal is in the sub-millisecond range, and it can Realize high-speed driving above 240Hz, which can effectively reduce the dynamic blur of moving images. When red, green and blue tricolor light-emitting diodes (RGB-LED) are used as the backlight source, no color filter film is required, and the field-sequential color time-sequence display can be realized by using the blue-phase liquid crystal; (2) The blue-phase liquid crystal does not need other various displays The alignment layer necessary for the mode...
