发明名称 ORGANIC LIGHT-EMITTING DIODE DISPLAY
摘要 An OLED display is disclosed. The display includes a display panel having a luminance level of the display panel, a power supply unit providing first and second power voltages to the display panel, and a gamma reference voltage generator configured to i) generate a compensation gamma reference voltage, ii) detect a voltage level of the first power voltage at a detection point of the display panel, ii) change the compensation gamma reference voltage from a first voltage level to a second voltage level within a frame based at least in part on the detected voltage level, and iv) determine the first voltage level of the compensation gamma reference voltage based at least in part on the luminance level.

主权项 1. An organic light-emitting diode (OLED) display, comprising: a display panel including a plurality of pixels and having a luminance level of the display panel; a power supply unit configured to provide first and second power voltages to the display panel; a gamma reference voltage generator configured to i) generate a compensation gamma reference voltage, ii) detect a voltage level of the first power voltage at a detection point of the display panel, iii) change the compensation gamma reference voltage from a first voltage level to a second voltage level within a frame based at least in part on the detected voltage level, and iv) determine the first voltage level of the compensation gamma reference voltage based at least in part on the luminance level; a gamma voltage generator configured to divide the compensation gamma reference voltage so as to output a plurality of gamma voltages; and a data driver configured to generate a data signal corresponding to the gamma voltages and provide the data signal to the display panel.
