Embodiment Construction

[0072] FIG. 1 is an embodiment of an image display system of the present invention. A pixel matrix 102 of the image display system includes a plurality of pixels (the detailed circuit of only one pixel 104 is shown in the figure for illustration). After the thin film transistor in the pixel 104 is turned on by a scanning signal line scan, the voltage value on a data signal line data will be written into the pixel 104 . In this embodiment, the pixel 104 is in the form of a 2T1C, which is only used to facilitate readers to understand the present invention, and is not intended to limit the scope of the present invention. Pixels with any other structure can be applied to the present invention.

[0073] Compared with the technology without moiré compensation - the gray scale value signal 108 output by an image frame source 106 is directly input into a digital / analog converter 110 to generate a voltage value and input to the pixel 104 through the data signal line data - The image ...

Abstract

The invention provides an image display system, not only discloses a method for collecting test data but also discloses various algorithms for eliminating the defect of cloud pattern; the invention does not need to change the structure of pixel and also large storage space is not needed; while the cloud pattern is eliminated, the algorithms disclosed by the invention can carry out dynamic adjustment for gamma parameters, white point setting and peak brightness according to the requirements of different users or different using environments and the difference from the traditional technique is that adjustment is needed to be carried out for the parameters by extra processes.

Description

technical field [0001] The present invention relates to an image display system, in particular to a method for eliminating mura defects of a display. Background technique [0002] Whether each pixel in the display is driven or not is determined by whether the thin film field effect transistor TFT in the pixel is turned on or not. However, the electronic characteristics of the thin film field effect transistor TFT are closely related to the precision of the process. Any slight deviation of the process will more or less change the electronic characteristics of the thin film field effect transistor TFT. Since it is difficult for the thin film field effect transistor TFT of each pixel to have consistent electronic characteristics, the light emitting conditions of all the pixels of the display are not consistent. The picture displayed on the monitor may have moiré defects (mura defects). [0003] A traditional solution is to change the pixel structure and directly add a moiré ...
