Abstract

A driving method for a liquid crystal display device, including: receiving original grayscale data; determining the colors of the first, second, and third subframes based on the original grayscale data; and simultaneously converting the grayscales of the first, second, and third subframes. The level value is the corresponding penetration; calculate the first and second turn-on time based on the penetration; convert the original gray-scale data into display gray-scale data based on the first and second turn-on time; during the display period of the first sub-frame Within the display period of the second sub-frame, the first light source is turned on, and during the display period of the second sub-frame, the second light source is turned on; during the display period of the third sub-frame, the third light source is turned on, and at the same time, the first and second light sources are turned on respectively. Turn on the first and second light sources; and provide display grayscale data to the liquid crystal display panel during the display periods of the first, second and third sub-frames.

Description

technical field

[0001] The present invention relates to a flat display technology, and in particular to a driving method for a field color sequential liquid crystal display device. Background technique

[0002] In the technical field of color sequential color display, a color sequential liquid crystal display can display a color within one frame by using three-color light sources of red (R), green (G) and blue (B). Sequentially emit light, so that the human eye produces a phenomenon of persistence of vision and mixes the three colors of light to achieve the effect of color display. Since RGB light-emitting diodes are used as the backlight of the backlight module, the color sequential LCD does not need to use color filters of different colors to achieve color display like the traditional LCD with white backlight. Effect. Therefore, the color sequential liquid crystal display can have a higher aperture ratio and transmittance than the traditional liquid crystal display. [...

Embodiment Construction

[0052] Embodiments of the present invention propose a liquid crystal display device and a driving method thereof, which can reduce the human eye's perception of different colors when they exist alone by incorporating part of the display time of sub-frames of different colors into the display time of the main sub-frame. The sensitivity of pure color, thereby reducing the color separation phenomenon of color sequential LCD. In order to make the content of the present invention more comprehensible, the following specific examples are given as examples in which the present invention can indeed be implemented. In addition, wherever possible, elements / components / steps using the same reference numerals in the drawings and embodiments represent the same or similar parts.
