Display apparatus, electronic appliance, and method of driving display apparatus

An electronic appliance comprising:

• a display apparatus including a display panel unit in which electro-optical devices that emit display light are arranged in the form of a matrix, and a control unit performing display grayscale control by sequentially selecting the electro-optical devices and driving the selected electro-optical devices in order with a first signal voltage and a second signal voltage based on an image signal,
• wherein the control unit divides a grayscale range that can be expressed by the second signal voltage into a plurality of areas and performs a grayscale interpolation operation for interpolating the display grayscales by the electro-optical devices by setting voltage values of the first signal voltage and the second signal voltage according to the grayscales of the image signal as commonly using respective setting information of the first signal voltage for each divided area of the second signal voltage.
