Title: SEMICONDUCTOR DEVICE, DISPLAY DEVICE, AND ELECTRONIC DEVICE
Abstract:
A semiconductor device with a novel structure is provided. The amount of data supplied to the semiconductor device for driving a display device including different display elements is reduced, so that the circuit area is reduced and power consumption is reduced. In a driver circuit for driving the display device including different display elements, gradation data to be applied to the display elements is generated. The generated gradation data given to different display elements are configured to differ in accordance with the designed luminance based on gradation data to be displayed and the intensity of reflected light based on illuminance data. Because the amount of data from the exterior to the driver circuit can be reduced, low power consumption due to a reduction in the data transfer rate, and a reduction in the circuit area due to a reduction in the size of an interface can be achieved.
