Abstract

A method for improving display panel display effect and a display panel are disclosed, the method includes: pre-acquiring an external compensation lookup table corresponding to each pixel grayscale 255 in the display panel; introducing the external compensation lookup table to the storage unit and replacing the data corresponding to an original grayscale 255 in the preset voltage table; driving the PWM driving circuit according to a replaced data. It combines the external compensation method to improve the display effect of the PWM digital drive and avoids the problem that the PWM circuit cannot eliminate the unevenness of the display panel in the grayscale 255 and enhance the actual display effect of the display panel.
