DISPLAY VOLTAGE COMPENSATION METHOD AND DEVICE THEREOF

WIPO Patent Application WO/2020/151415

A1

A display voltage compensation method and a device thereof. The display voltage compensation method comprises: obtaining a first detection voltage and a second detection voltage when the display voltage is respectively a first preset value and a second preset value, and calculating a ratio of the first detection voltage to the second detection voltage (S101); obtaining a threshold voltage corresponding to the ratio of the first detection voltage to the second detection voltage from a preset corresponding table (S102); obtaining a current display voltage (S103); calculating a compensation coefficient according to the threshold voltage (S104); and compensating for the current display voltage according to the threshold voltage and the compensation coefficient (S105). By means of the method, obtaining the corresponding threshold voltage by means of the ratio of different detection voltages corresponding to the display voltage is achieved, and the compensation coefficient is calculated according to the threshold voltage to compensate for the current display voltage, and the technical problem in the prior art that the temperature affects the current display voltage and affects the display effect is solved.
