Embodiment 1

[0048]According to Fig. 1 and Fig. 2, the present invention comprises main control unit 1, display driver 2 and display panel 3, and main control unit 1 comprises initialization module 11 and color setting module 12, and initialization module 11 carries out system initialization, main control unit 1 to The display driver 2 sends display data information, and the color setting module 12 generates a color adjustment ratio and sends it to the display driver 2 .

[0049] As shown in Figure 1, the display driver 2 includes a color adjustment module 21, the color adjustment module 21 receives the color adjustment ratio sent by the color setting module 12, and adjusts the color data according to the adjustment ratio to generate a corresponding pixel voltage, and displays Panel 3 shows the corresponding color.

[0050] As shown in Figure 2, the basic control process of this embodiment is as follows:

[0051] 1) The color setting module 12 in the main control unit 1 generates the adju...

Embodiment 2

[0056] According to Fig. 3 and Fig. 4, the present invention comprises main control unit 1, display driver 2 and display panel 3, and main control unit 1 comprises initialization module 11 and color setting module 12, and initialization module 11 carries out system initialization, main control unit 1 to The display driver 2 sends display data information, and the color setting module 12 generates a color adjustment ratio and sends it to the display driver 2 .

[0057] Specifically, as shown in FIG. 3 , the color setting module 12 includes an adjustment data interface submodule 121 and a calculation submodule 122, wherein the adjustment data interface submodule 121 receives the YCbCr color adjustment value and sends it to the calculation submodule 122, and adjusts The data interface sub-module 121 receives the setting data of the relatively external input device 4 .

[0058] As shown in Figure 3, the calculation sub-module 122 performs RGB color data conversion according to the...

Embodiment 3

[0076] According to Fig. 5 and Fig. 6, the difference between this embodiment and Embodiment 2 is: in this embodiment, the display driver 2 also includes a memory 22, and the adjustment ratio values ​​of the R, G, and B components are stored in the memory 22, and the color adjustment The module 21 makes corresponding adjustments according to the adjustment ratio value stored in the memory 22 .

[0077] As shown in Figure 6, the specific control process of this embodiment is as follows:

[0078] I. The adjustment data interface sub-module 121 in the main control unit 1 receives the YCbCr color adjustment value sent by the input device 4, and forwards it to the calculation sub-module 122.

[0079] II. The calculation sub-module 122 calculates the R, G, and B components of the corresponding RGB color data according to the received adjustment value, and generates the adjustment ratio value of each component.

[0080] III. The calculation sub-module 122 sends the adjustment ratio ...

Abstract

This invention relates to a color adjustment method and a system for display terminals of a display device, in which, the method includes: a primary adjustment unit generates color adjustment ratio, a display drive corrects colors according to the color adjustment ratio and a display panel displays related color, concretely, a CPU generates a rate of RGB color data, the display drive adjusts them independently according to the rate of the R, G, B compoments to generate corresponding pixel voltages, the system includes a primary unit, a display drive and a panel, and the CPU includes an initialized module characterizing that the CPU also includes a color set module generating color adjustment ratio, the drive includes a color adjustment module receiving the rate sent by the set module to adjust the color data and generate related pixel voltage to be displayed by the panel.

Description

technical field [0001] The present invention relates to a display device, in particular to a method and system for adjusting color of a display terminal. Background technique [0002] At present, in the color flat display technology, such as LCD, OLED or other types, the color picture is regarded as a pixel matrix composed of a limited number of pixels. The independent pixel display points constitute a pixel point matrix, and each pixel point is composed of three adjacent relatively independent red, green and blue sub-pixel points. When the red, green, and blue components of a pixel are different, the pixel can show different colors. [0003] The existing display terminal consists of a main control unit, a display driver, and a display panel. After power-on reset, the main control unit completes the initial setting of the drive circuit; then, the main control unit sends the received display data to the display driver, and the display driver processes the display data, outp...
