Abstract
Provided is an image display device capable of dynamically controlling the D-V characteristics of a display panel while suppressing fluctuation in characteristic for each display panel. The display panel has a panel display portion including a red pixel, a green pixel, and a blue pixel. A storage unit stores V-L characteristic data measured in advance of RGB. A D-L calculation unit calculates D-L characteristic data of RGB based on the display setting values stored in a register. A D-V calculation unit calculates D-V characteristic data of RGB based on the V-L characteristic data stored in the storage unit and the D-L characteristic data calculated by the D-L calculation unit. A DAC generates a driving voltage corresponding to a video signal input from a timing controller based on the D-V characteristic data calculated by the D-V calculation unit and applies the driving voltage to each pixel.
