Driving control method of color-sequence liquid crystal colorful display

Abstract

The present invention relates to a driving control method of a color-sequence liquid crystal colorful display. The converting delay of a liquid crystal optical gate channel caused by liquid crystal optical response delay can be shortened, and further, the optical flux is improved to enable coloring saturation degree better; then, the liquid crystal optical gate channel can be more matched with the control of poor light to enable poor light with different colors to have non-luminous time in conversion, and the non-luminous time is overlapped with the converting delay of a liquid crystal optical gate channel caused by liquid crystal optical response delay to avoid the poor light with different colors mixing in the time of delay conversion, so displaying color difference caused by color mixing can be avoided, and correct original design derivative colors can be generated.

Description

technical field [0001] A display method of a color-sequence liquid crystal color display, especially a driving control method of a color-sequence liquid crystal color display that improves luminous flux and increases color saturation. Background technique [0002] The color sequence liquid crystal color display is mainly through the sequential switching of the multi-color backlight, so that it passes through the liquid crystal light gate channel, and by controlling the closing and opening of the liquid crystal light gate channel, a sequential original pure color image field is generated, which is passed through the human eye. Persistence of vision and color mixing produce colorful display, refer to figure 1 As shown, the control signal sequence 1 is used to drive the liquid crystal light gate channel to close and open. However, the liquid crystal light gate channel is limited by the response time of liquid crystal molecules, and the penetration curve 2 of the liquid crystal ...

Problems solved by technology

[0003] together with reference figure 2 As shown, the liquid crystal light gate channel is used in conjunction with the backlight 5 of the multi-color backlight that is sequentially switched (the icon is the sequential switching of red light 6 (R), green light 7 (G), and blue light 8 (B). When the pure colors of light 6, green light 7, and blue light 8 (labeled in the diagram: r, g, b), the penetration curve 2 of the liquid crystal light gate channel will cover the light of the subsequent color because of the closing time delay 4, and also That is, when the red light 6 is displayed, part of the green light 7 will also pass through, when the green light 7 is displayed, part of the blue light 8 will pass through, and when the blue light 8 is displayed, part of the red light 6 will pass through, thus causing a deviation in the displayed color

In addition, when it is used to display the mixture of two kinds of light (labeled in the diagram: c, m, y), it will also cause the light of the subsequent color to penetrate due to the closing time delay 4, so that the resulting display The color will have a color shift of the derived color

[0004] Refer again image 3 As shown, known, in order to solve the above problems, there is a method of adjusting the control signal timing 1A of the liquid crystal color display to change the penetration curve 2A of the liquid crystal light gate channel, so that the opening time delay of the penetration curve 2A is 3A and the closing time The time delay 4A completely falls within the backlight 5A of the same color, which solves the color shift phenomenon that the display color will have derivative colors, but it will reduce the luminous flux of red light 6A, green light 7A, and blue light 8A, resulting in color intensity and saturation The degree is not good, it is difficult to meet the requirements on the display
