Problems solved by technology

But this has led to another serious problem. If the difference between light and dark in the upper and lower areas is too large, it is easy to produce large-scale flicker (Flicker) phenomenon due to the lack of spatial balance effect.
[0011] From the above, it can be clearly seen that there is a problem of uneven color tone in the upper and lower areas in the prior art. If it is improved by increasing the operating frequency, the hardware cost will increase; if it is improved by reverse scanning, it will lead to more serious screen flickering problems.

Embodiment Construction

[0040] FIG. 7A is a system architecture diagram of an inverse scanning display device according to a preferred embodiment of the present invention, please refer to FIG. 7A . It includes a video source 710 , a field sequential display controller 720 , a frame memory 730 , a backlight module 740 and a panel module 750 . Wherein the video source 710 provides video data. The field sequential display controller 720 also includes a data stream change unit (Data Stream Change Unit) 722, a memory control unit (Memory Control Unit) 724, a timing control unit (Time Control Unit) 726 and an input / output buffer 728 (I / O Buffer).

[0041] The sub-unit data stream conversion unit 722 of the field sequential display controller 720 is responsible for converting the spatial parallel RGB signal source of the video source 710 into a temporal serial R→G→B signal output. The video data is often quite large, so the frame memory 730 is required to store data for the field sequential display contr...

Abstract

The invention discloses an interlacing-reversing scanning displaying method and a corresponding device which adopts the interlacing-reversing scanning to realize the scanning process. And scanning can be alternatively distributed to both upper and lower zones besides the lower-half zone for each color-image zone lacking of penetrating-brightness on both time and space, and then when images are displayed continuously the invention can balance the unequal color distributions in the upper and lower zones and can effectively reduce the appearance of image flashing.

Description

technical field [0001] The present invention relates to a display method and its device, and in particular to a staggered inversion scanning display method and its device. Background technique [0002] In recent years, due to the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanel Display) has flourished. Among them, Liquid Crystal Display (LCD for short) takes advantage of its advantages of low voltage operation, no radiation scattering, light weight and small size, and gradually replaces traditional cathode ray tube displays and becomes the mainstream of display products. [0003] The liquid crystal display is mainly composed of a liquid crystal panel (Liquid Crystal Panel) and a backlight module (Black Light Module, referred to as B / L). Since the liquid crystal injected into the liquid crystal panel does not emit light, the surface light source provided by the backlight module must be used to light the liqui...
