Abstract
The invention provides a display device and a display method. The display device comprises a display panel and a driving chip, the driving chip comprises a voltage regulating unit, an overvoltage driving unit and a triggering unit; the trigger unit is used for detecting whether the current display picture of the display panel is a heavy-load picture or not, and when the display picture is the heavy-load picture, the trigger voltage regulation unit and the overvoltage driving unit are triggered to work cooperatively; the voltage adjusting unit is used for adjusting a target driving voltage corresponding to a target gray scale in the liquid crystal driving voltmeter, so that the lighting effect reaches the preset brightness when the display panel displays a white picture; the overvoltage driving unit is used for starting a driving function, adjusting the parameter configuration table and performing overvoltage driving on a data line of the display panel based on the parameter configuration table and the target driving voltage so as to improve the charging rate of the heavy-load picture, so that the charging rate is improved by detecting the heavy-load picture and cooperatively adjusting the voltage and overvoltage driving, and the charging efficiency is improved. The method has the advantages of improving the charging rate of a heavy-load picture, eliminating display defects and improving the display quality.
