Liquid crystal displayer based on prism color sequence method

Abstract

The invention provides a liquid crystal displayer based on a prism color sequence method. The liquid crystal displayer comprises a backlight module, a first liquid crystal box and a second liquid crystal box. The backlight module comprises a red LED, a green LED and a blue LED which provide red light, green light and blue light sequentially and alternately. The first liquid crystal box comprises multiple blue-phase liquid crystal lenses switched with the backlight LEDs of the backlight module synchronously so as to gather light of corresponding colors from the backlight module. The second liquid crystal box is located above the first liquid crystal box and used for receiving light from the first liquid crystal box so as to provide a corresponding displayed picture. Compared with the prior art, the design structure of the two liquid crystal boxes is adopted, the lower liquid crystal box gathers the backlight penetrating through pixels to specific pixels to achieve the focusing function, and the upper liquid crystal box receives the focused light to achieve the picture display purpose. Due to the fact that only the operation that the blue-phase liquid crystal lenses in the lower liquid crystal box are switched with the backlight LEDs synchronously is needed, liquid crystals in the upper liquid crystal box do not need to be switched along with the backlight LEDs, and the frame rate meeting the requirement for the liquid crystal response speed can be maintained.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display based on a prism color sequential method (Lens Sequential Color, LSC). Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of Flat Panel Displays. Among many flat panel displays, Liquid Crystal Displays (LCD) have high space utilization, low power consumption, no radiation and low Features such as electromagnetic interference have gradually become the mainstream of the market. Generally, a liquid crystal display includes a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not have the characteristic of self-illumination, a backlight module must be disposed under the liquid crystal panel to provide the surface light source required by the liquid crystal panel, so that the liquid crystal display can display images for users to watch. ...
