摘要: A backlight control system for controlling a backlight of a display. The display (100) comprises a transmissive display panel (102) and a backlight (104) for providing an illumination to a backside (108) of the display panel. The backlight comprises light sources (110) positioned at light source positions for providing illumination to the backside of the display panel. The system comprises a drive value generator (106) for providing light source drive values (112) for causing the backlight profile to gradually descend around a high luminance portion of the display at a rate that is independent of a position of the high luminance portion with respect to the light source positions. The high luminance portion of the display has a higher luminance than an area around the high luminance portion of the display. The system allows to prevent a disturbing perception of backlight structure and halo.

摘要: An active matrix display device comprises an array of display pixels provided over a common substrate. Each pixel has a voltage-programmed current source circuit, a drive transistor and a light sensitive device for sensing the display element light output. The light sensitive device provides a current dependent on the display element output, and the light sensitive device and the current source circuit define a feedback control loop which controls the voltage provided to the gate of the drive transistor. This pixel circuit uses a current source circuit to provide a gate voltage to a drive transistor. This enables the current source circuit to operate at low current levels, and therefore under low voltage stress.

摘要: A system (102) comprising a box (104) for implanting in a mamMal body part (106), which box is provided with a first electrical contact (110, 121, 114, 116, 118, 120), and a module (108) for accommodating in the box, which module is provided with a second electrical contact (122, 124, 126) for cooperation with said first electrical contact. The first electrical contact and the second electrical contact are mutually movable, at least in a stationary accommodation of the module in the box, between a contact position in which said first and second electrical contacts are electrically connected, and a non-contact position in which said first and second electrical contacts are separated from each other.
