The present invention provides a gray-scale voltage calibration device, system, method and display device. The gray-scale voltage calibration device includes: an adjustment module, which is used to receive the actual gray-scale voltage value of the gray-scale to be adjusted output by the integrated circuit of the source driver, and set the The actual gray-scale voltage value is compared with the theoretically set voltage value, and when the comparison result shows that the actual gray-scale voltage value is not equal to or not close to the theoretically set voltage value, the actual gray-scale voltage value is adjusted; the verification module is used to verify the adjusted Whether the gray scale voltage value is equal to or close to the theoretical set voltage value, if yes, the adjusted gray scale voltage value is fed back to the source driver integrated circuit as the target voltage value input to the display panel, otherwise, the control adjustment module continues to adjust The final gray scale voltage value is adjusted. The gray scale voltage calibrating device of the present invention can calibrate the actual gray scale voltage value output by the source driver integrated circuit so that it is equal to or close to the theoretically set voltage value.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a gray scale voltage calibration device, system, method and display device. Background technique [0002] The source driver integrated circuit (source IC) is used to provide the gray scale voltage for the display panel to drive the display panel to display the picture. When the source driver integrated circuit is in harsh environments such as high and low temperature, and the power supply voltage is unstable, the actual gray scale voltage value output by the source driver IC There may be a difference from the theoretical set voltage value, resulting in distortion of the picture displayed on the display panel. Contents of the invention [0003] In view of this, the present invention provides a grayscale voltage calibration device, system, method and display device to solve the problem that the actual grayscale voltage value output by the existing source driver integrate...
