Embodiment Construction

[0022] The present invention adopts changing the order of the color field: changing the order of the color field in each image arbitrarily, so that the order of the color separation stripes is no longer fixed, and the periodicity of the appearance of the color separation stripes is destroyed, reducing the degree of attention.

[0023] When the frequency of the green subfield is lower than 50 Hz, human eyes will perceive flickering. Under the principle of not destroying the edge color complementarity of the color sequence method, by increasing the sub-color field or inserting the frequency of the white sub-color field to compensate for the flicker phenomenon perceived by the human eye, the color separation phenomenon can be effectively suppressed and the brightness of the picture can be increased. Embodiments of the present invention will be explained in detail below.

[0024] In the first embodiment, if Figure 2A Shown is a driving method for a backlight source (not shown in...

Abstract

The invention discloses a method for driving a backlight source. The backlight source can provide three light sources, which are a red light source, a blue light source and a green light source respectively. The driving method comprises the following steps of: dividing a picture display interval into four subintervals; lighting up the green light source twice at two subintervals of the first picture display interval respectively; and lighting up the three light sources in the four subintervals according to a first sequence in the first picture display interval and lighting up the three light sources in a second picture display interval according to a second sequence, wherein the first sequence and the second sequence are different from each other.

Description

[0001] This application was submitted by the applicant on November 1, 2007, with application number: 200710168284.5, and is a divisional application named "Backlight Driving Method". 【Technical field】 [0002] The invention relates to a method for driving a backlight source, which improves the color separation phenomenon of the color sequence method by changing the arrangement of the turn-on sequence of the light sources. 【Background technique】 [0003] The existing color-sequential liquid crystal display technology utilizes the method of temporal color mixing to generate various color images. Such as Figure 1A As shown, the method is to divide a picture section 11 into a first subsection 111, a second subsection 113, and a third subsection 115, and turn on the red light source in the first subsection 111 and the second subsection 113 separately. The green light source and the blue light source are separately turned on in the third sub-interval 115 . The sequence of turnin...
