Abstract: 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.

Abstract: A device for restricting the movement of a printed circuit board to which tactile switches are mounted. The device which prevents a relative movement of the printed circuit board with respect to a bracket to facilitate the installation of the printed circuit board while structuring the securing means for the circuit board so that a force is exerted that counters forces created by the activation of switches directly mounted to the main printed circuit board. The printed circuit board retaining device acts to maintain the printed circuit board in the appropriate location with respect to the supporting bracket while preventing the fracturing of tactile switches when an excess force is applied to the tactile switches.
