摘要:
A system and method of ambient light detection with digitized output. A light sensitive device is coupled to electronic circuitry for receiving an output of the light sensitive device corresponding to a level of ambient light. The electronic circuitry compares the output to a threshold level. The threshold level corresponds to a desired level of light. The electronic circuitry for provides an output signal indicative of said desired level of light.

An integrated Sensing package structure includes a substrate made of IR blocking material. The substrate has a first receiving compartment and a second receiving compartment concavely formed on the top surface thereof. The first receiving compartment has a reflective layer formed on the surface of the inner wall thereof. A LED unit is disposed in the bottom portion of the first receiving compartment. A plurality of first conducting lines is electrically connected to the LED unit and extends to an outer surface of the substrate. An IR sensing chip is disposed in the second receiving compartment. A plurality of second conducting lines is electrically connected to the IR sensing chip and extends to an outer surface of the substrate. An IR block cover is covered on the top surface of the substrate, forming at least one opening corresponding to the IR sensing chip.

摘要:
In one embodiment, a touch detection system and method is achieved having high resolution by forming an integrated array of alternating emitters and detectors. Using integration techniques, the detectors can be made much larger than the emitters while the gaps between the emitters and detectors are maintained relatively small. Thus, high resolution is achieved without dramatically increasing the number of emitter/detector pairs. In one embodiment each array is positioned on an edge of a display such that the emitter of one array is lined up (on axis with) a detector of an opposing display. In one embodiment, the touch detection system and method operates to detect the amplitude of signals arriving from opposing arrays so as to precisely determine the location of a touched position. Off-axis scanning can be employed to increase sensitivity.
