Embodiment Construction
[0026] In order to improve the display effect of image color, the present invention discloses a color management system and its driving method, which can enable each pixel in the display screen to have a more flexible adjustment space for high-level and low-level, so as to Each pixel can show a more coordinated display quality. Hereinafter, various embodiments of the present invention will be disclosed and described in detail with reference to the accompanying drawings.
[0027]Firstly, the present invention provides a driving method, which can be applied in a display, for example, there is at least one pixel in a display image, wherein each pixel has at least three sub-pixels, and each sub-pixel is at its target color level The following is composed of at least one group of gray levels, and the so-called gray levels can be divided into a combination of a high level and a low level. Therefore, as shown in FIG. 1 , it is a flow chart of the main steps of the driving method of ...

The invention discloses a color management system and a driving method thereof. The system comprises an arithmetic logical unit, a signal processing unit, a sequential control unit and a display unit, wherein, according to standard of the color level of one pixel, the high color levels and the low color levels of the pixels, which are subjected to time sequence processing or not, are converged in a color level resolution by the recursive algorithm; the color level resolution has an optimal brightness and conforms to the chromaticity coordinate from the front view and the minimum difference of the chromaticity from the front view and from the side view; and with the color level of one of the pixels as a reference by using a recursive algorithm, the optimal color level resolution is used as a reference to display sub-pixels in the display unit for video playing. By using the color management system, all sub-pixels in a same pixel can be adjusted at the same time with the mutual color levels as reference, so that the displayed color effect is more harmonious and uniform.
Description
technical field [0001] The present invention relates to a management system and its method, in particular to a color management system and its driving method. Background technique [0002] The development of display technology is advancing rapidly. Modern displays can accurately represent the brightness and color changes in the physical world. However, for a display system with a single pixel having three primary colors of red, green, and blue, two of the primary color sub-pixels When a pixel changes color level and another primary color sub-pixel has a fixed color level, the high color level and low color level in the fixed color level sub-pixel will not have different combination changes due to the change of the color level of the other two sub-pixels For example, the color levels of the first red, green, and blue sub-pixels are (160, 120, 100), and the high and low color levels corresponding to the color levels of the blue primary color sub-pixels are (137, 30), at this ...
