Problems solved by technology

[0005] At present, there are many conversion algorithms for converting RGB display three-color display signals to RGBW four-color display signals, but these conversion algorithms will cause serious color loss (color loss) in RGB display signals in RGBW four-color display signals. As a result, the image quality of the display product is lost, and the display effect of the image display product

Embodiment 1

[0026] This embodiment provides a display method, such as figure 1 As shown, it includes: Step 101: Receive an input RGB signal.

[0027] Step 102: Convert RGB signals to CMYK signals.

[0028] This step specifically includes: calculating and obtaining CMY intermediate signals according to the RGB signals, calculating and obtaining K intermediate signals according to the CMY intermediate signals, taking the minimum value of the K intermediate signals among the CMY intermediate signals, and calculating and obtaining CMYK signals according to the CMY intermediate signals and the K intermediate signals.

[0029] Step 103: converting the K signal in the CMYK signal into a W signal.

[0030] In this step, the W signal is obtained by inverting the K signal in the CMYK signal. It should be noted that while the W signal is obtained through the above steps, the gray scale of the W signal has also been synchronously determined.

[0031] The conversion of the above-mentioned RGB signa...

Embodiment 2

[0042] This embodiment provides a display system, such as image 3 As shown, it includes an input module 1, which is used to input RGB signals, and also includes a conversion module 2, which is electrically connected to the input module 1, and the conversion module 2 is used to receive RGB signals and convert RGB signals into CMYK signals, And convert the K signal in the CMYK signal to the W signal.

[0043] Among them, the conversion module 2 includes a calculation sub-module 21 and an inversion sub-module 22. The calculation sub-module 21 is used to calculate and obtain the CMY intermediate signal according to the RGB signal, calculate and obtain the K intermediate signal according to the CMY intermediate signal, and obtain the K intermediate signal according to the CMY intermediate signal and the K intermediate signal. The signal is calculated to obtain the CMYK signal, wherein the K intermediate signal is the minimum value among the CMY intermediate signals; the inversion ...

Abstract

The invention provides a displaying method and system. The displaying method comprises the steps that input RGB signals are received, the RGB signals are converted into CMYK signals, and K signals in the CMYK signals are converted into W signals. According to the displaying method, the RGB signals can be converted into RGBW signals, accordingly, image displaying brightness is greatly improved, meanwhile, after signal converting, the fact that the RGB signals have no color loss can be guaranteed, therefore, color loss during RGBW signal displaying is greatly lowered, and then image displaying quality and displaying effect are greatly improved. The advantages of the displaying system can be also achieved by arranging a conversion module.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display method and a display system. Background technique [0002] In recent years, with the continuous improvement of the performance of display products, the requirements for display products are gradually developing in the direction of large screen and high resolution, and at the same time, low power consumption is also required. [0003] The traditional RGB (red, green, blue pixels) three-color display technology cannot solve the problem of achieving high resolution and low power consumption at the same time. Therefore, RGBW (red, green, blue, white pixels) four-color display technology has appeared at present. technology. RGBW display technology has successfully improved the brightness of display products due to the addition of white pixels (W pixels) on the basis of traditional RGB display technology. [0004] After adding white pixels, it is first necessary t...
