Abstract: A mobile unit and a system for a mobile unit which can judge whether an oncoming car is emitting a high beam are provided. A mobile unit and a system for a mobile unit which include a first and a second sensors, a memory circuit, an arithmetic circuit, and a window portion. The first sensor is configured to sense the position of the eyes of a driver who is riding in the mobile unit. The second sensor is configured to sense whether an oncoming car is existing, whether the oncoming car is emitting a high beam, and a region that is to be irradiated with the high beam. The memory circuit is configured to store an irradiation distance of a high beam and a decrease rate of light transmittance of the window portion. The arithmetic circuit is configured to output, to the window portion, data on a region of the window portion in which the light transmittance is to be changed, on the basis of data sensed by the first sensor and the second sensor and data stored in the memory circuit. The window portion is configured to locally decrease the light transmittance on the basis of the data output from the arithmetic circuit.

Abstract: A display device which can display a clear image and can display an image with low power consumption is provided. The display device includes an arithmetic circuit having a function of generating first to third display data, a first display portion, and a second display portion. The arithmetic circuit has a function of detecting a color region and a gray-scale region of the generated first display data and generating the second display data corresponding to an image to be displayed on the first display portion and the third display data corresponding to an image to be displayed on the second display portion, on the basis of the detection results.
