The method includes: dividing a display panel into at least two display areas; and for each divided display panel, controlling a gate driving integrated circuit to drive multiple gate lines in the display area in turn and a data driving integrated circuit to drive data lines in the display area simultaneously to lighten pixels in the display area, and performing a Gamma voltage tuning on the display area whose pixels are lightened. The display panel is divided into display areas and the tuning of Gamma voltage values is performed for each divided display area respectively; therefore the tuning of Gamma voltage for large size display panels is more accurate, which can effectively improve the uniformity of the picture display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gamma voltage tuning method and gamma voltage tuning system","description":"Provided are a Gamma voltage tuning method and a Gamma voltage tuning system.
