Abstract
The present application relates to a voltage compensating circuit and a display. The voltage compensating circuit includes: an electroluminescence device; a driving unit, used for driving the electroluminescence device; a luminescence time length control unit, respectively connected with the driving unit and the electroluminescence device, and used for controlling luminescence time length of the electroluminescence device; and a compensation unit, respectively connected with the driving unit and the luminescence time length control unit, and used for providing a compensation voltage to the voltage compensating circuit. Through the voltage compensating circuit in the present application, a dropped voltage value is compensated, thereby brightness uniformity of the display is improved, and image quality is improved.
