Embodiment Construction

[0060] The invention provides a mixed color sequence control method of a backlight module and a display device using the method. In this control method, a mixed color sequence algorithm is provided to control the backlight module of the RGB light-emitting diodes to produce a backlight technology with high contrast. Since the liquid crystal display panel and the LED backlight module are synchronously controlled, the color field separation effect and the motion blur (Motion Blur) problems caused by the traditional color sequence method can be suppressed, and the contrast value can be improved. At the same time, this hybrid color sequence algorithm also has the effect of suppressing the color field separation effect and the motion blur (Motion Blur) problem for the display panel of the Optically Compensated Bend (OCB) display panel without a color filter-less (Color Filter-less).

[0061] The invention provides a driving method of a backlight module and a display device using the...

Abstract

A mixed color sequence control method for a backlight module and a display unit for the control method are disclosed. The control method provides a mixed color sequence algorithm to control the backlighting module of a RGB LBD to produce highly contrastive backlighting. Since a liquid crystal display panel and the backlight module of the LBD are controlled synchronously, the problems of color field separation effect and motion blur in conventional color sequence control method are avoided in the method of the invention, thus improving contrast ratio. Meanwhile, the mixed color sequence control method has effects in restraining color field separation effect and motion blur on a color filter-less optical compensated bend OCB display panel.

Description

technical field [0001] The invention relates to a driving method of a display, and in particular to a driving method using a mixed color sequence method to eliminate color field separation and improve display contrast, and a display device using the method. Background technique [0002] With the development of optoelectronic and semiconductor technologies, the vigorous development of flat panel displays has been driven. Among many flat-panel displays, liquid crystal displays have become the mainstream in the market because of their superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. The liquid crystal display includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not have the function of emitting light, a backlight module is configured to provide the backlight required by the liquid crystal display panel, so that the liquid c...
