The method comprises steps of: capturing grayscale images of the TFT-LCD to be tested which are displayed under a series of specific grayscale voltages; calculating grayscale information corresponding to the images according to the captured grayscale images, so as to obtain a Gamma curve; determining an uneven area in the Gamma curve based on the grayscale information corresponding to two adjacent grayscale voltages; calculating depth of the uneven area; and adjusting amplitude of any one or both of the two adjacent grayscale voltages based on the depth so that the Gamma curve between the two adjacent grayscale voltages is even. The present disclosure can improve the Gamma curve, thus eliminating the display color cast or the brightness abnormity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gamma curve adjusting method and adjusting device for TFT-LCD to address problems caused by uneven gamma curve","description":"The present disclosure provides a method and a device for adjusting a Gamma curve of TFT-LCD.
