摘要： The present disclosure is directed to a method and apparatus for estimating ambient light conditions for an OLED display. Embodiments of the method and apparatus use one or more columns of OLEDs in the display to perform two functions: their typical function of emitting light in a display mode, and the additional function of sensing light in a sense mode. To perform the additional sense mode functionality, the one or more columns of OLEDs in the display are temporarily placed into a photovoltaic and/or photoconductive mode. A sensing circuit is used to measure this current produced by the one or more columns of OLEDs while operating in the sense mode and report it back to a controller. The controller can then use this information to estimate the ambient light conditions of the environment where the OLED display is currently operating and to perform a touch and/or proximity sensing function.

摘要： A thin film circuit comprises a plurality of thin film transistors, wherein the output response of the circuit is dependent on at least first (36) and second (34, 22) of the transistors. The first thin film transistor (36) is, in use, exposed to a source of illumination (2) and the second thin film transistor (16) is shielded from the source of illumination. The first thin film transistor (36) is operated in use as an analogue switch which provides an analogue output in response to a control input. The illumination of this transistor reduces the effect of dynamic threshold voltage variations, which can be a limitation to circuit performance.
