<p>A matrix display device (32) comprising at least one structured layer, arranged on a substrate and formed so as to include a code (31), detectable by a pointing device (33) to determine a position on the display (32). Providing the pixel structure with a location code can be achieved by relatively simple modifications of the manufacturing process. Therefore, the code can be incorporated in the display device in a very cost efficient manner, typically not increasing the manufacturing cost of a conventional matrix display. It will therefore either reduce the cost price of devices where a touch screen is already present or greatly improve the functionality of many products where a touch screen is at present too expensive. ® KIPO & WIPO 2007</p> |
