Abstract
Display devices and methods forming the same. A digitizer sensor board is integrated on an upper substrate or a lower substrate of a display panel to provide a display device. In the display device, the display panel displays images, and the digitizer sensor board is integrated into the display panel to sense position of a position pointer or finger contact on a surface.
Claims29
A display device, comprising:
- a display panel, wherein the display panel comprises an upper substrate having a color filter and a lower substrate having a thin film transistor (TFT) array;
- a digitizer sensor film integrated in the display panel for sensing position of a position pointer on a surface of the display panel;
- and
- a control unit coupled to the display panel and the digitizer sensor film according to an image signal from a host system via an interface, driving the display panel and generating a scan timing signal to the digitizer sensor film,
- wherein the display panel further comprises a non-transparent area generated by a black matrix in the color filter, in the top substrate, and coils and conductor wires in the digitizer sensor film are formed in the non-transparent area.
