The luminous efficiency of the blue pixel material can be improved, the current of blue light can be reduced, and the uniformity of a display picture can be improved; also from a side view, the voltage drop over the transmission line is minimized. At present, the main method for solving the problem is a pixel-level compensation algorithm, the optical performance of each pixel point needs to be accurately measured so as to correct data, and the method needs a special customized-level drive IC to meet the requirement, so that the cost is overlarge.
