Problems solved by technology

[0004] However, due to the inherent light valve opening delay effect of liquid crystal molecules, neither of these two methods can solve the problems of motion jitter and motion blur, and also occupy a large amount of storage resources and increase hardware costs.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The gist of the present invention is to use R, G, B three primary color LED arrays to form a backlight source, add a time-division circuit to control the three primary color backlight drive circuits, and drive the RGB backlight LEDs of the three primary colors to emit light independently in turn to form a three primary color backlight source. LCD pixels are driven by three-primary-color LED backlights, so that each frame of image is divided into three primary-color images in time sequence, such as figure 1 shown.

[0024] The pixel value method corresponding to different primary colors can be that when the corresponding primary color emits light, the pixel drive circuit controls the TFT (Thin Film Transistor, Thin Film Field Effect Transistor) field effect tube of the LCD pixel to open the light valve according to the light transmissio...

Abstract

The invention discloses a LCD, the implementation method thereof and a tricolor LBD backlight source system. The backlight source system comprise a tricolor LBD drive circuit and a backlight source composed of at least a tricolor LBD; the backlight source system also comprises a tricolor drive control circuit; the tricolor drive control circuit is connected with the tricolor LBD drive circuit forreceiving the time-division logical synchronization signal and controlling the tricolor LBD drive circuit to drive the backlight source; wherein, the time-division logical synchronization signal is provided with the time-division multiplexing imaging information of the primary color image frames and used for controlling the synchronization of the primary color frame signals and the backlight source in the time-division multiplexing. The tricolor LBDs are controlled through the time-sharing mode to emit the lights in the primary colors so that the problems of motion jitter and motion blur are solved; the resolution is improved; large quantity of storing resources are avoided and the hardware cost is reduced.

Description

technical field [0001] The present invention relates to light-emitting diode backlight technology, in particular to a three-primary-color light-emitting diode backlight, a liquid crystal display using the three-primary-color light-emitting diode backlight, and a realization method thereof. Background technique [0002] The prior art adopts LED (Light Emitting Diode, light-emitting diode) as the backlight source, and at present, the LED backlight source generally adopts the color filter (CF) to separate the three primary colors from the white light to drive the LCD (Liquid Crystal Display, liquid crystal display) of the corresponding color. display) pixels. [0003] On this basis, the general method of the existing technology to solve the motion jitter and motion blur of the liquid crystal display is: insert a black frame or an image frame between two frames; frame. 120Hz / 100Hz technology shortens the display time between each frame, and increases the refresh rate of the sc...
