Problems solved by technology

[0002] In LCD, OLED and other display devices, RGB (red, green, blue) color rendering technology is often used for display. The defect of this technology is that the display brightness is low, which increases the power consumption of the device. Displaying in the RGBW (red, green, blue and white) color space can increase the display brightness and save power consumption, but RGBW display often has problems such as reduced color saturation and unnatural color transitions, and the display effect is good. Bad is directly related to whether the technology can achieve mass production of equipment

Embodiment 1

[0123] The design idea of ​​Embodiment 1 of the present invention is: first convert the RGB color space to the HSV (hue, saturation, brightness) color space, then increase the brightness V while keeping H and S in the HSV color space unchanged, and then Convert HSV color space to RGBW color space.

[0124] Specifically, as figure 1 As shown, the method includes the following steps:

[0125] S1. The LCD module inputs the RGB data of each pixel through LVDS and other signal lines, and converts the input red R, green G, and blue B color values ​​into the HSV color space:

[0126]

[0127]

[0128] v=max

[0129] Among them, r represents the input color value of R, g represents the input color value of G, b represents the input color value of B, max represents the maximum value among r, g, and b, and min represents the value among r, g, and b. The minimum value, h for hue, s for saturation, and v for lightness.

[0130] S2. While keeping the hue H value and saturation S ...

Embodiment 2

[0190] The embodiment of the present invention also provides a processing system for RGB data, including:

[0191] The first conversion module is used to convert the input R, G, B three color values ​​to the HSV color space;

[0192] The brightness adjustment module is used to adjust the value of the brightness V while keeping the hue H value and the saturation S value of the HSV color space unchanged;

[0193] The second conversion module is used to convert the H, S and V values ​​processed by the brightness adjustment module from the HSV color space to the RGBW color space.

[0194] The brightness adjustment module is specifically used to adjust the value of the brightness V using a Gaussian function, V(RGBW)=V(RGB)*y, wherein,

[0195] Where y is the brightness adjustment coefficient, A is the amplitude of the Gaussian function, a is the parameter that determines the half-width of the Gaussian function, s is the saturation value, and B is the adjustment value when s is e...

Abstract

The invention relates to the technical field of color space conversion, and discloses a method and a system for processing RGB (Red, Green, Blue) data. The method comprises the following steps of S1, converting three input color values of R, G and B into an HSV (Hue, Saturation, Value) color space; S2, under the condition of remaining a hue H value and a saturation S of the HSV color space value unchanged, adjusting a value of brightness V; and S3, converting the H value, the S value and the V value processed through the step S2 into the RGBW (Red, Green, Blue, White) color space from the HSV color space, and displaying. The RGB color space is converted into the HSV color space, the brightness V is improved under the condition of remaining the H and the S in the HSV color space unchanged, and the HSV color space is converted into the RGBW color space, so that the brightness can be improved while better hue and color saturation are maintained and color transition is natural.

Description

technical field [0001] The invention relates to the technical field of color space conversion, in particular to a method and system for processing RGB data. Background technique [0002] In LCD, OLED and other display devices, RGB (red, green, blue) color rendering technology is often used for display. The disadvantage of this technology is that the display brightness is low, which increases the power consumption of the device. Displaying in the RGBW (red, green, blue and white) color space can increase the display brightness and save power consumption, but RGBW display often has problems such as reduced color saturation and unnatural color transitions, and the display effect is good. Bad is directly related to whether the technology can realize mass production of equipment. [0003] Therefore, how to improve display brightness while maintaining good hue, color saturation and natural color transition is a technical problem to be solved urgently.
