The method includes receiving an RGB value of each second pixel of a displayed image, and determining a brightness value of each first pixel according to the RGB value of each second pixel. The method also includes determining a local brightness adjustment factor and a global brightness adjustment factor by performing statistics processing for local region brightness values and global image brightness values according to the brightness value of each first pixel; and calculating a brightness drive signal corresponding to the first pixel, according to the brightness value of each first pixel, the local brightness adjustment factor and the global brightness adjustment factor. The brightness drive signal adjusts a transmittance of a corresponding pixel of the first panel. The global brightness adjustment factor adjusts an output brightness value of a corresponding pixel of the first panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of enhancing contrast and a dual-cell display apparatus","description":"The present disclosure describes methods of contrast enhancement and dual-cell display apparatus.
