TFT DISPLAY, OLED-INTERFACE, AND METHOD FOR DETECTING THE SPATIAL POSITION OF RIMS IN A SPATIAL REGION DISPOSED UPSTREAM OF A DISPLAY

Document Type and Number:

WIPO Patent Application WO/2011/128116

Kind Code:

A3

Abstract:

The invention relates to a TFT liquid crystal display which serves as such for reproducing image contents. The invention is based on the object of providing solutions which make it possible, in the case of devices which are equipped as such with a display, to realize an input interface for input operations in a particularly advantageous manner. This object is achieved according to the invention by means of an LC display comprising a polarization layer, a first substrate layer, a first electrode structure, which comprises a multiplicity of pixel electrodes and is applied to the first substrate layer, a liquid crystal layer, and a second electrode structure, which is embodied as a whole-area transparent electrode layer (VCOM) and functions as a counterelectrode with respect to the multiplicity of pixel electrodes, wherein the LC display is equipped with a sensor device, for detecting the finger or hand of a user in a region disposed upstream of the LC display, wherein the aforementioned second electrode structure functions as a field providing electrode of said sensor device.
