Method and Device for Compensating Display Voltage

A device for compensating display voltage, comprising:

• a first acquisition circuit, configured to acquire a first detected voltage and a second detected voltage corresponding to display voltages of a first preset value and a second preset value respectively;
• a first calculation circuit, configured to calculate a ratio of the first detected voltage to the second detected voltage;
• a second acquisition circuit, configured to acquire a threshold voltage corresponding to the ratio of the first detected voltage to the second detected voltage from a preset correspondence table;
• a third acquisition circuit, configured to acquire a current display voltage;
• a second calculation circuit, configured to calculate a compensation coefficient according to the threshold voltage;
• and
• a compensation circuit, configured to compensate the current display voltage according to the threshold voltage and the compensation coefficient.
