ABSTRACT:
A display device has a predetermined display region and includes an array substrate equipped with a drive circuit, and a light sensor for measuring outside illuminance and a temperature sensor both installed on the array substrate. A control method for the display device includes using the light sensor to measure outside illuminance and using an output of the temperature sensor to correct an output of the light sensor, thereby adjusting luminance in the display region. The display device may further include an opposed substrate in opposition to the array substrate, a liquid crystal layer sandwiched between the two substrates to form the predetermined display region, and a backlight, thereby constituting a liquid crystal display device. Another configuration of a display device has a predetermined display region and includes an array substrate equipped with a drive circuit for display, and a light sensor installed on the array substrate for measuring outside illuminance, a filtering circuit for filtering a signal output from the light sensor and a processing circuit for processing the signal output from the light sensor and then filtered with the filtering means.
