Representing a quantum leap forward in touch panel technology, Samsung Electronics recently announced that it began mass production of 40-inch ‘Optical Sensor in Pixel’ LCD panels in November this year.



How does it work?  The Optical Sensor in Pixel LCD panel detects reflected images of an object on the panel using built-in Infrared sensors. With optical sensors in each pixel of the panel, the new panel can much more accurately assess touch sensitivity compared to existing touch panels.


Using next-generation image sensing technology, the Optical Sensor in Pixel panel can detect more than 50 touch points simultaneously. This advanced panel can also display images with Full HD resolution and provide wide-angle viewing. The multi-touch functionality of Samsung’s ‘optical sensing per pixel’ technology should be well received by many professional consultants including stock brokers and financial analysts. Also, it can be an invaluable tool in eDesk applications for schools or business conference rooms



In a further display of next-generation functionality, all of the input functions of a keyboard, mouse or scanner can be carried out right on the panel itself.  The panel can be installed in a variety of positions, including table top and wall-mounted settings. And don’t be afraid to try it out; its tempered glass is strong enough to withstand external loads of over 80 kilograms.



As the panel can perform touch and multi-touch sensing and image display simultaneously, it represents a new paradigm for massively interactive communications, compared to the one-way communication of today’s kiosk touch panels.


The Optical Sensor in Pixel LCD panel has been installed in ‘Samsung SUR40 for Microsoft® Surface®’, a table-type PC product, co-developed by Samsung Electronics and Microsoft®. SUR 40 has been available for pre-order since last month.
