Display screen hue correction method and display device

The invention provides a tone correction method of a display screen and a display device. The method comprises the following steps: driving the display screen to work based on a first tone curve; acquiring the current environment temperature; detecting whether the current environment temperature is in a first preset temperature interval or not; when the environment temperature is in a first preset temperature interval, the first tone curve is switched to a second tone curve which is pre-loaded to a temporary storage subunit of the driving unit, the display screen is driven to work based on the second tone, and the second tone curve is a tone curve which is pre-compensated to correspond to the first preset temperature interval. When the environment temperature is detected to be in the first preset temperature interval, the first hue curve is rapidly switched to the second hue curve, the phenomena of brightness attenuation, color temperature and hue shift, white balance deviation and the like are effectively av
