Abstract
A color display panel and a control method thereof are provided. The color display panel includes pixel units arranged in an array, and each pixel unit at least includes a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, and a white sub-pixel unit, where white light of the color display panel is achieved through the white sub-pixel unit. With aid of the above, the white light of the color display panel of the disclosure is realized by a single white sub-pixel unit, which can effectively alleviate color separation during mixing of red, green, and blue light of traditional display panels, and greatly improve the display effect of the display panel.
Claims11
A color display panel comprising:
- pixel units arranged in an array, wherein each pixel unit at least comprises a red sub-pixel unit, a green sub-pixel unit, a blue sub-pixel unit, and a white sub-pixel unit, wherein white light of the color display panel is achieved through the white sub-pixel unit.
A control method applicable to a color display panel, the method comprising:
- acquiring a value of a red channel, a value of a green channel, and a value of a blue channel in an input signal;
- determining whether the red channel, the green channel, and the blue channel have a same value;
- turning on a white sub-pixel unit in the color display panel and turning off a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit in the color display panel, based on a determination that the red channel, the green channel, and the blue channel have the same value;
- and
- determining a gray value of the white sub-pixel unit according to the same value and controlling a brightness value of the white sub-pixel unit according to a y curve, such that the color display panel displays brightness and color corresponding to the input signal.
