[0005] Existing liquid crystal display devices generally preset multiple display modes corresponding to different ambient light color temperatures for users to choose from, for example, a warm color temperature display mode with an ambient light color temperature of 5000K, and a standard color temperature display mode with an ambient light color temperature of 6500K. And the ambient light color temperature is 9300K cool color temperature display mode, etc. However, when users select these settings, they can only choose one of these fixed display modes. When the display effects of the above-mentioned display modes are not good, they cannot Accurately adjusting the display effect of the liquid crystal display device according to the actual color temperature of the ambient light, the user experience is not high, and some existing systems in the prior art that adjust the display effect in real time according to the color temperature of the ambient light will reduce the effective display effect of the liquid crystal display device. Gray scale, and consequently the displayed image suffers from loss of detail

Embodiment Construction
[0038] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.
[0039] see figure 1 , the present invention provides a display method, comprising the following steps:
[0040] Step S1 , providing a display panel 1 and a gamma chip 2 electrically connected to the display panel 1 .
[0041] Specifically, the gamma chip 2 has a plurality of binding point grayscales, and each binding point grayscale corresponds to a brightness.
[0042] Step S2: Detect the current color temperature of the ambient light, and when the difference between the current color temperature of the ambient light and the initial color temperature reaches a preset color temperature threshold, calculate the first gray color according to the current color temperature of the ambient light and a preset ratio algorithm The initial color tempe...

The invention provides a display method and a display device. According to the display method, a current color temperature of ambient light is detected; according to the current color temperature of the ambient light and a preset matching algorithm, a maximum grayscale capable of driving a display panel for displaying under the current color temperature of the ambient light under current configuration of a gamma chip is obtained, so that a maximum brightness value for displaying under the current color temperature of the ambient light of the display panel is obtained; the configuration of thegamma chip is adjusted according to the maximum brightness value for displaying under the current color temperature of the ambient light of the display panel, so that all grayscales that can be displayed by the display panel are mapped into a brightness range from 0 to a first brightness value; and then the adjusted gamma chip is used for driving the display panel to carry out displaying. The display effect can be adjusted automatically with the color temperature change of the ambient light; and the image details are not lost.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display method and a display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] A liquid crystal display panel is a core component of a liquid crystal display device. A liquid crystal display panel is usually composed of a color filter substrate (Color Filter Substrate, CF Substrate), a thin film transistor array substrate (Thin FilmTransistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. ) constitutes. Generally, pixel electrodes and common ...
