Abstract:
A current value of a first pixel and/or a current value of a second pixel of a display are adjusted until a value of a current difference is within a predetermined range. The current value of the first pixel corresponds to a brightness level of the first pixel. The current value of the second pixel corresponds to a brightness level of the second pixel. Adjusting the current value of the first pixel involves adjusting a threshold voltage value of a transistor of the first pixel. Adjusting the current value of the second pixel involves adjusting a threshold voltage value of a transistor of the second pixel.
