Problems solved by technology

[0005] However, as can be seen from the above, the known spatial color mixing method needs to add color filters of different colors to a single pixel, so that it takes an extra process to manufacture the color filters of different colors to be added, thus increasing the process cost
In addition, the known temporal color mixing method need

[0024] Please refer to figure 2 versus image 3 , figure 2 Is a schematic diagram of a color display system of the present invention, image 3 It is a flowchart of a color display method of the present invention. Such as figure 2 As shown, the color display system 100 of the present invention includes an image input unit 102, an arithmetic unit 104, and a display device 106. The display device 106 includes a plurality of pixel units (not shown) and a first backlight source 108. And a second backlight source 110. Such as image 3 As shown, the color display method of the present invention includes the following steps:

[0025] Step S100: Use the image input unit 102 to input a color signal 112 into the arithmetic unit 104;

[0026] Step S200: Next, according to a color conversion method, the color signal 112 is converted into a first color output signal 114 and a second color output signal 116 by the arithmetic unit 104;

[0027] Step S300: Then, sequentially output the first col...

Abstract

The invention discloses a color conversion method. The method comprises the following steps: firstly, receiving a color signal; secondly, calculating saturation to acquire a saturation value of the color signal, and calculating hue angle weight to acquire a first hue angle weight value of the color signal corresponding to a first search table and a second hue angle weight value of the color signal corresponding to a second search table; and thirdly, performing operations on colors, converting the color signal to a first color output signal according to the saturation value and the first hue angle weight angle, and converting the color signal to a second color output signal according to the saturation value and the second hue angle weight angle.

Description

technical field [0001] The present invention relates to a color conversion method and its corresponding color display method, especially to a color conversion method and its corresponding color display method, which are used in a display device with dual backlight sources to increase the scope of the color gamut . Background technique [0002] Generally, a traditional display uses three primary colors of red, green and blue in a single pixel to mix a desired display color, and then displays a desired image by combining a plurality of pixels of different colors. Since the color displayed by a single pixel is mixed with the predetermined three primary colors of the display, the displayed color is limited to the color gamut of the three primary colors used, and the display cannot correctly display the color of the image. [0003] The known methods for increasing the color gamut can be roughly divided into two types, namely, a space color mixing method and a time color mixing m...
