Embodiment Construction

[0032] see figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the display of the present invention. The display 100 includes a memory 10 , a timing controller 12 , a scan driver 14 , a data driver 16 and a display panel 18 . The memory 10 is connected to the timing controller 12 . The timing controller 12 is also connected to the scan driver 14 and the data driver 16 respectively. The scan driver 14 and the data driver 16 are also connected to the display panel 18 . The memory 10 stores a compensation look-up table for compensating the gray scale of the data signal. In this embodiment, the memory 10 stores a plurality of compensation look-up tables, such as the first, second and third gray scale compensation look-up tables 111 , 112 , and 113 , respectively corresponding to the three primary colors of the data signal. For example, for the RGB color system, the first grayscale compensation lookup table 111 is used to compensate the grayscal...

Abstract

The invention provides a display, which comprises a memory, a signal processing unit and a display panel, wherein the memory stores a reference gray scale, a gray scale compensation value of the reference gray scale and a series of gray scale compensation differences; the signal processing unit reads a plurality of gray scale data stored in the memory and receives a data signal with an input gray scale; the signal processing unit selects one or a plurality of gray scale compensation differences corresponding to the input gray scale from the series of gray scale compensation differences according to the received input gray scale and the scale number difference of the reference gray scale; the gray scale compensation value of the input gray scale is obtained by calculation according to the gray scale compensation value of the reference gray scale and the selected gray scale compensation difference so as to compensate the input gray scale of the data signal; the display panel receives the data signal which is output by the signal processing unit and is provided with the compensated gray scale; and according to the data signal with the compensated gray scale, a corresponding picture is displayed. In addition, the invention also provides a driving method for the display.

Description

technical field [0001] The invention relates to a display and a driving method thereof. Background technique [0002] With the development of science and technology, users have higher and higher requirements on display effects of displays (such as liquid crystal displays, plasma displays, and organic electroluminescent displays, etc.). Among them, the color temperature (Color Temperature) is one of the important parameters to measure the display effect of the display. If the color temperature of the display corresponds to different gray scales, the difference between the color temperature of the display is large, and the picture displayed on the display and the actual item will appear different in chromaticity. more severe distortion. [0003] In order to improve the color temperature effect of the display, currently the industry generally adopts to adjust the Gamma curve data of the three primary colors (RGB), and store the adjusted gray scale compensation value correspond...
