The present disclosure provides a luminance compensation method and device therefor, a readable storage medium, and a display device, in the present disclosure, the luminance values of all the subpixels are obtained, and then the luminance value of the subpixel with the most serious aging degree among all the subpixels, that is, the minimum luminance value is obtained. Then, the minimum luminance value is compared with the standard luminance value to obtain the compensated luminance value, and then the compensated luminance value is used to drive all the subpixels, so that the uniformity of the luminance of the display device is improved.

Luminance compensation method and device, readable storage medium, and display device

A detection method and a detection device for a display panel are provided. The detection method includes: performing a detection operation on pixel-driving circuits. The detection operation includes applying a gate voltage and a source voltage to a gate and a source of each driving transistor, to turn on a driving transistor; and sampling voltages at the sources. The detection operation is repeated n times, where in each repetition, the gate voltage is the sum of the gate voltage in the initial detection operation and an accumulative addition of a difference between the gate voltage and the sampled voltage in the previous detection operation, with n being a positive integer. Based on the sampled voltage of the driving transistor of each pixel-driving circuit obtained in the n-th repetition of the detection operation, it is determined whether the threshold voltage of the driving transistor in the pixel-driving circuit is abnormal.
