Embodiment Construction

[0042] The present invention will be described with preferred embodiments and viewpoints. Such descriptions are to explain the structure and steps of the present invention, and are only used for illustration rather than to limit the patent scope of the present invention. Therefore, in addition to the preferred embodiments in the description, the present invention can also be widely implemented in other embodiments.

[0043] The present invention uses a computing unit to convert the mixed-color brightness detected by the light sensor into pure-color brightness of red, green and blue according to the proportional relationship between the brightness of the light-emitting diode and the current through matrix operation. , in order to facilitate the color correction and compensation of the look-up table.

[0044] First introduce the color correction system disclosed in the present invention, hereby refer to figure 2 , this figure depicts a preferred embodiment of a color sequentia...

Abstract

The invention provides a color correction system and method of a color sequential display. The invention is characterized in that the mixed-color light brightness values of a first color field, a second color field and a third color field detected by a photoelectric detector are converted into a red pure-color light brightness value, a green pure-color light brightness value and a blue pure-color light brightness value by an arithmetic element according to the matrix operation designed in the invention so as to facilitate subsequent color correction and white balance compensation, thereby achieving the effects of suppressing the color separation phenomenon and maintaining the normal color correction and compensation.

Description

[0001] technical field [0002] The invention relates to a color correction method, in particular to a color correction method and a color correction system used in a color sequential display. Background technique [0003] In the past liquid crystal display, it is necessary to configure color filters above the pixels to filter the light source and present the color to be displayed, and the human eye receives the red, green and blue light displayed by the light source after passing through the color filter, and can It mixes, and then perceives the color of this pixel. However, the color filter will affect the overall light transmittance of the liquid crystal display. In addition, the color filter will also affect the size of the display dot (dot) of a single pixel of the liquid crystal display, resulting in the resolution of the liquid crystal display being limited by the color filter. limits. [0004] In order to improve the above-mentioned problems of resolution and light...
