摘要： Display driver circuits are described for driving organic light emitting diode displays, particularly passive matrix displays, with greater efficiency. The display drivers comprise a controllable current generator to provide a variable current drive output to an OLED display, the current generator comprising at least one bipolar transistor in series with the current drive output. The display brightness is adjustable by controlling the current generator to vary the current drive to the display. Preferably the bipolar transistor has an emitter terminal substantially directly connected to a power supply line of the driver to reduce losses in the driver. A corresponding method is also described. By employing a bipolar transistor current drive and varying display brightness by controlling the current an efficient driver-display combination is obtained.

摘要： A touch sensing system comprising a touch sensor optical system to project light defining a touch sheet above a surface; a camera to capture a touch sense image from the touch sheet, comprising light scattered by an object; and a signal processor to process the touch sense image to identify a lateral location of the object on the surface. A brightness of the projected light is modulated to define bright, touch detecting intervals and dark intervals. The camera and the light projection are synchronised such that the camera captures scattered light during the bright touch detecting intervals and rejects ambient light during the dark intervals. The system further comprises a pen. The pen comprises a photodetector to detect the projected light, a light source detectable by the camera, and a controller coupled to control the light source such that it is selectively illuminated during touch detecting intervals in synchronism with the projected light of the touch sheet. In a further invention, the pen includes a reflector towards the tip of the pen, a tip-touch sensor to sense touching of the tip and a controller to activate the pen from a low power state when touching of the tip is detected.

摘要： A touch sensing system comprises: an optical beam source 304 (such as an infrared laser) to provide an optical beam 308; a pair of controllable beam deflectors 302 comprising at least first and second beam deflectors, where the first beam deflector 302a is configured to deflect the optical beam through a first angle towards a touch sensing region, and the second beam deflector 302b is configured to deflect scattered light from an object 318 in the touch sensing region through a second angle; a detector 324; and an imaging system 322 to image the deflected scattered light from the second beam deflector onto the detector, where the first and second beam deflectors are controlled in tandem to scan the touch sensing region. The deflectors may be faces of a rotatable polygonal mirror, or phase locked MEMS deflectors. The detector may be a photodiode array, and the location of scattered light imaged onto the array may be dependent on a distance to a sensed object 318. A deflector may deflect light into a different plane to provide a three dimensional touch sensing region. A plurality of sensing systems may provide multitouch sensing. The system may be used in an interactive whiteboard.
