STATEMENT UNDER ARTICLE 19 (1 )
The present claims are directed to an integrated display that comprises both light emitters in the form of inorganic light-emitting diodes (iLEDs) and touch screen electrodes. Inorganic light-emitting diodes (iLEDs), can be smaller than conventionally used light emitters for displays, such as organic light emitting diodes (OLEDs) or liquid crystal display (LCD) elements. As such, the use of iLEDs in an array arrangement provides sufficient space between rows of the array to dispose electrodes of the touch screen between them. If iLEDs are not used, the light emitters are large (e.g., as with OLEDs or LCDs) and the area covered by the touch electrodes is consequently small. The use of iLEDs provides room for the electrodes to be disposed as recited in the present claims.
