Abstract
A method for compensating large view angle Mura area of a flat display, comprising the steps of: 1) providing a flat panel including a number of main pixels, and a Mura area and a normal area; 2) setting two or more than two main pixels as a set of Mura area brightness adjustment units; 3) providing a driving circuit for driving the number of main pixels within the flat panel, and the driving circuit supplying a number of gamma voltages; and 4) using the driving circuit to apply two or more than two different gamma voltages to the set of main pixels within the Mura area brightness adjustment units such that the gray scales of Mura area within a center view area and the large view angle area are closer to the gray scales of the normal area thereby achieving a uniform brightness across the flat panel. Accordingly, with the method provided, the gray scales of the central view and the large view angle of the Mura area are substantially closer to the gray scales of the normal area. The yield of the flat panel is increased, and the quality of the flat display using such a flat panel is also guaranteed.
