Abstract
Provided are a brightness control method and apparatus for a display panel. The brightness control method includes: loading a measurement pulse-signal to a source of a first thin film transistor of a brightness measurement module in a display panel and a source of a second thin film transistor of a reference module, loading an adjustment control-signal to a gate of the first and second thin film transistors, the adjustment control-signal is a fixed voltage signal, the range of a voltage difference between the adjustment control-signal and a drain of the second thin film transistor is −2V-2V, the voltage range of an active level of the measurement pulse-signal is 3V-14V; detecting a brightness measurement signal output by the brightness measurement module, detecting a reference signal output by the reference module; adjusting the brightness of the display panel by means of detected brightness measurement signal and reference signal.
