Description

technical field

[0001] The present invention relates to a display device having a photosensor in a display pixel portion and a frame area around a display surface, and an electronic device using the display device. Background technique

[0002] A technique is known in which high screen luminance is ensured in the case of high ambient illuminance and low screen luminance is secured in the case of low ambient illuminance by detecting the illuminance of external light with a photosensor. This technology not only provides an easy-to-view screen, but also contributes to reducing power consumption of a backlight system in the case of a liquid crystal display device that displays images through a backlight. In addition, this technology helps to extend the battery life of mobile applications such as mobile phones. Accordingly, various such techniques are being researched.

[0003] In addition, several technologies have been proposed, among which are designed to provide a display d...
