| 发明名称 | Method of compensating gamma reference voltages, and gamma reference voltage compensation circuit | ||
| 摘要 | In a method of compensating gamma reference voltages includes setting a plurality of emission signal on-duty ratios that have different values in a range from 0% to 100%, setting a plurality of data offsets for the emission signal on-duty ratios and each of the data offsets being set based on a color shift, the color shift being caused according to the emission signal on-duty ratios, generating a plurality of compensation gamma reference voltages by multiplying a gamma reference voltage by the data offsets, and applying the compensation gamma reference voltages to an organic light emitting display panel in dimming ranges that include the emission signal on-duty ratios, respectively. | ||

| 主权项 | 1. A method of compensating gamma reference voltages, the method comprising: setting a plurality of emission signal on-duty ratios that have different values in a range from 0% to 100%; setting a plurality of data offsets for the emission signal on-duty ratios, each of the data offsets being set based on a color shift, the color shift being caused according to the emission signal on-duty ratios; generating a plurality of compensation gamma reference voltages by multiplying a gamma reference voltage by the data offsets; and applying the compensation gamma reference voltages to an organic light emitting display (OLED) panel in dimming ranges that include the emission signal on-duty ratios, respectively. | ||
