1results about How to "Uniform luminance" patented technology

The display device provided in the application detects the pixel voltages of the first to-be-detected sub-pixel and the second to-be-detected sub-pixel electrically connected to the same data line through the detection module. The first to-be-detected sub-pixel is a sub-pixel in which the first transistor electrically connected to the data line is turned on to write the data signal, and the second to-be-detected sub-pixel is a sub-pixel in which the second transistor electrically connected to the data line is turned on to write the data signal. The pixel voltage of the first to-be-detected sub-pixel is related to the turn-on degree of the first transistor, and the pixel voltage of the second to-be-detected sub-pixel is related to the turn-on degree of the second transistor. The compensation module provides a compensation signal to the clock signal control module according to the detection result of the detection module. The voltage value of the first clock signal for controlling the turn-on of the first transistor or the voltage value of the second clock signal for controlling the turn-on of the second transistor is compensated by the clock signal control module, so that the luminance of the sub-pixels on the same data line is consistent, and the brightness and darkness uniformity of the display picture is improved.
