Title:
- Optical Sensors Embedded within AMLCD Panel: Design and Applications
Presenter(s):
Description:
A new approach to data input into AMLCD panels has been conceived and demonstrated. This integrates an array of TFT optical sensors into the a-Si backplane of the AMLCD. The concept, design considerations, and specific applications such as touch panel input, hand recognition, and image capture will be discussed.
