摘要： A driving device for a display and a display using same, and a driving method of the display are provided. The display includes a display panel on which an image is displayed, and at least one optical sensor (photodetector) to detect the intensity of ambient (external) light incident upon the display panel. An external-brightness detector outputs an external-brightness signal based on the intensity of external (ambient) light and a backlight brightness controller changes the brightness of the image displayed (or backlight) on the display panel according to the external-brightness signal. The driving device may be implemented on an integrated circuit adapted to be connected to external-light photodetectors of type 1 or of type 2. The driving device may be may be dynamically configured to generate the external-brightness signal by sensing a voltage level of the light detecting node in a first mode of operation and may be reconfigured to generate the external-brightness signal by sensing a current level of the light detecting node in a second mode.

摘要： A light source apparatus includes a light source module, a luminance determiner, an illuminance sensor and a light source driver. The light source module provides a display panel with light. The luminance determiner obtains luminance data of first image data including at least white image data that is converted from image data of a red color, a green color and a blue color. The illuminance sensor obtains sensing data based upon an external illuminance. The light source driver drives the light source module based upon the luminance data and the sensing data.
