摘要： A display device is provided which displays images by emitting light when a reference voltage is applied to pixels. An average picture level calculation unit of a reference voltage calculation unit in a rectangular wave driving unit of a TFT substrate calculates the value of average picture level, and a ΔV calculation unit of a reference voltage calculation unit calculates a correction amount ΔV of the reference voltage based on the average picture level value. The calculated correction amount ΔV is added to a reference voltage and is used as the voltage of a rectangular wave signal that is output to each pixel from a rectangular wave driving unit. In each pixel in which a data signal corresponding to the grayscale value is stored, an organic EL device emits light in accordance with the rectangular wave signal.

摘要： 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.
