Abstract

The invention provides a color adjusting method and device and display equipment. The color adjusting method comprises the following steps: acquiring a blue light component of a current screen pixel and current system time; if the current system time is in the night period, carrying out gamma correction on the blue light component by adopting a first color lookup table function; and if the current system time is not in the night time period, carrying out gamma correction on the blue light component by adopting a second color lookup table function, wherein the slope of the first color lookup table function is smaller than that of the second color lookup table function. Through the mode, the blue light intensity in the night time period can be reduced, so that the eyesight is protected, the sleep quality is improved, the protection effect on the human body is improved, and the light intensity in the non-night time period can be ensured.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a color adjustment method and device, and a display device. Background technique [0002] In the past, most displays were cathode ray tube displays. These displays have a physical property that twice the input voltage does not produce twice the brightness. The input voltage produces a brightness of approximately the 2.2 power of the input voltage, which is called the display gamma factor. As a result, the information in the bright area is brighter than expected, and the information in the dark area is darker than expected. Therefore, gamma correction of the input voltage is required, through a new exponential function, exponented by the reciprocal of the gamma coefficient of the device. [0003] In the prior art, the light intensity of the electronic product screen is usually adjusted according to the ambient light intensity. Although this method can improve the co...
