Patent ID: 8368656

Claim:
An electroluminescent display touch panel comprising: a base substrate comprising: a plurality of scan lines disposed on the base substrate; a plurality of data lines disposed on the base substrate, and intersecting the scan lines to define a plurality of pixel regions, wherein each of the pixel regions includes a display region and a non-display region, and the non-display regions include at least a first group, a second group and a third group; a plurality of pixel switching devices disposed correspondingly in the display regions of the base substrate; a plurality of electroluminescent devices disposed correspondingly in the display regions, each of the electroluminescent devices comprising a first electrode, a second electrode and an illumination element disposed between the first electrode and the second electrode, wherein the first electrode is electrically connected with the pixel switching device; a plurality of readout devices disposed in the first group of the non-display regions of the base substrate; a plurality of sensing pads disposed in the first group of the non-display regions of the base substrate and electrically connected with the readout devices correspondingly; a plurality of first spacer pads disposed in the second group of the non-display regions of the base substrate; a plurality of second spacer pads disposed in the third group of the non-display regions of the base substrate, wherein the first group, the second group and the third group of the non-display regions are different; and an encapsulating substrate disposed opposite to the base substrate, the encapsulating substrate comprising: a plurality of first spacers disposed on a surface of the encapsulating substrate facing the first spacer pads in the second group of the non-display regions of the base substrate correspondingly, and contacting the first spacer pads correspondingly for maintaining a cell gap between the base substrate and the encapsulating substrate; a plurality of second spacers disposed on the surface of the encapsulating substrate facing the second spacer pads in the third group of the non-display regions of the base substrate correspondingly, and each of the second spacer is substantially not in contact with the second spacer pad, correspondingly; a plurality of sensing spacers disposed on the surface of the encapsulating substrate facing the sensing pad in the first group of the non-display regions of the base substrate correspondingly; and a conductive layer disposed on a surface of the sensing spacers facing the sensing pads.
