Abstract:
1. A display comprising: a display panel that displays an image; an external-brightness detector including a light detecting node configured to be connected to a first photodetector configured to detect ambient light while the external-brightness detector operates in a first mode and configured to be connected to a second photodetector configured to detect ambient light while the external-brightness detector operates in a second mode; and wherein the external-brightness detector outputs a digital external-brightness signal based on sensing the light detecting node and wherein the digital external-brightness signal is based on measuring the analog voltage level of the light detecting node while the external-brightness detector operates in the first mode while connected to the first photodetector and by measuring the analog electric-current level of the light detecting node while the external-brightness detector operates in the second mode while connected to the second photodetector; and a brightness controller that controls the brightness of the image displayed on the display panel according to the digital external-brightness signal.
