Problems solved by technology

[0003] However, due to the relative speed between the human eye and the image, when the color sequential liquid crystal display mixes colors and displays the image in the way of RGB rotation, the three sub-frames corresponding to RGB cannot completely overlap on the observer's retina, Or because the object flashes quickly in front of the monitor or when the observer blinks, only some colors are revealed and the colors cannot be overlapped. This phenomenon is generally called Color Breakup (CBU), and this phenomenon will be serious. greatly affect the quality of the image, and even cause discomfort to the observer

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.

[0053] figure 1 It is a schematic diagram of a liquid crystal display device according to an embodiment of the present invention. Please refer to figure 1 , the liquid crystal display device 100 applied to the dr...

Abstract

Disclosed is a method for driving a liquid crystal display device. The method comprises: receiving raw gray scale data; according to the raw gray scale data, deciding the color of a first subframe, a second subframe and a third subframe; simultaneously converting the gray scale values of the first subframe, the second subframe and the third subframe to be corresponding penetration; according to the penetration, calculating a first unlatching time and a second unlatching time; according to the first unlatching time and the second unlatching time, converting the raw gray scale data to display gray scale data; within the display period of the first subframe, unlatching a first light source, and within the display period of the second subframe, unlatching a second light source; within the display period of the third subframe, unlatching a third light source, and at the same time, according to the first unlatching time and the second unlatching time, respectively unlatching the first light source and the second light source; and within the display periods of the first subframe, the second subframe and the third subframe, providing the display gray scale data to a liquid crystal display panel.

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. [...
