Embodiment 1

[0022]The first embodiment of the present invention achieves the purpose of the present invention by changing the grayscale value in the time domain. The display method for compensating the color deviation of the front-view image and the side-view image according to the first embodiment of the present invention is applied to a display, such as a liquid crystal display. Please refer to FIG. 4 , which shows a system architecture diagram of a liquid crystal display according to a first embodiment of the present invention. The liquid crystal display includes a plurality of pixels, a plurality of data drivers 402 , a plurality of scan drivers 404 and a controller 406 . The controller 406 further includes a corrected grayscale value generator 407 . The following takes the pixel P(i, j) as an example for illustration. The pixel P(i, j) is any pixel of the liquid crystal display, and i and j are positive integers. The liquid crystal display displays a frame within a frame period FP....

[0033] The second embodiment of the present invention achieves the purpose of the present invention by changing the gray scale value in the space domain. The display of the present invention that can compensate for the color deviation of the front-view image and the side-view image displays a frame within a frame period FP. The display can be a liquid crystal display. The liquid crystal display includes a liquid crystal display panel, multiple data drivers, multiple scan drivers and a controller. There are multiple pixels on the liquid crystal display panel, and the controller further includes a generator for correcting gray scale values. The following takes the first pixel Pa and the second pixel Pb as an example for illustration. The corrected gray scale value generator is used to generate a first corrected gray scale value GRa1 and a first gray scale value GRa1 for a first original gray scale value GRa0 of the first pixel Pa and a second original gray scale value GRb0 of ...

Abstract

This is a kind of display means and display that can compensate the color windage of the front-looking and side-looking images. The screen time series is divided into several subaltern screen time. At first, several emendated gray-rank values are brought from a original gray-rank value of the contraposed image pels. Thereinto the original gray-rank value series is corresponded to a original front-looking and side-looking normalization lighteness. Then in the subaltern screen time, drive the image pels with several voltages respectively corresponding to these emendated gray-rank values. Each of these image times and its corresponding emendated gray-rank value fixes on a emendated front-looking and side-looking normalization lighteness. The summation series of the absolute value of the difference between the emendated front-looking normalization lighteness and the corresponding emendated side-looking one is less than the absolute value of the difference between the original front-looking normalization lighteness and the corresponding original side-looking one.

Description

【Technical field】 [0001] The present invention relates to a display method and display for compensating color deviation, and in particular to a display method and display for compensating color deviation of front-view images and side-view images. 【Background technique】 [0002] Please refer to FIG. 1 , which shows a system architecture diagram of a traditional liquid crystal display. In the following, a liquid crystal display (LCD Panel) 100 with a resolution of 1024×768 is taken as an example for illustration. The liquid crystal display 100 has 1024×3 data lines (Data Lines) and 768 scan lines (Scan Lines) for driving 1024 rows of red pixels, green pixels and blue pixels. The data lines and the scan lines are respectively driven by a data driver (Data Driver) 102 and a scan driver (Scan Driver) 104 . The data driver 102 is controlled by a data control signal Cntl_D output by a controller 106 , and sequentially receives a plurality of pixel data (Pixel Data) PD transmitted...
