ELECTROLUMINESCENT DISPLAY AND METHOD OF DRIVING THE SAME
摘要
An electroluminescent display (10) and a method of driving the same are disclosed. In one aspect, the display includes a display panel (40) including a plurality of pixels (PX) configured to operate based on a first power supply voltage (ELVSS)having a negative voltage level. The display panel (40) is configured to generate at least one feedback voltage (VFB) corresponding to an ohmic drop (IRD) of the first power supply voltage (ELVSS). An analog-to-digital converter (50) is configured to generate at least one digital feedback signal (DG_VFB) based on the at least one feedback voltage (VFB). An adaptive voltage controller (20)is configured to generate a voltage control signal (DG_ELVSS) based on input image data (RGB_DATA), the at least one digital feedback signal (DG_VFB), a distribution of the input image data and the ohmic drop (IRD) of the first power supply voltage (ELVSS). A voltage converter (30)is configured to generate the first power supply voltage(ELVSS) based on an input voltage (VIN) and the voltage control signal (DG_ELVSS).
