Abstract
The present disclosure provides an OLED touch panel, comprising: a substrate; a cathode and an anode, arranged on the substrate, wherein the cathode comprise a plurality of sub-cathodes; and at least one touch driving electrode, arranged on a same layer as the anode and separated from the anode, wherein the touch driving electrode is disposed to be intersected with the sub-cathodes; wherein the OLED touch panel is configured to, at a displaying phase, apply a driving signal for displaying on the cathode or the anode, so as to drive an OLED device, and applying, at a touching phase, a driving signal for touching on the touch driving electrode, so that at least a part of the sub-cathodes are operated as touch sensing electrodes, to output a touch sensing signal. The present disclosure also provides a display apparatus comprising the above OLED touch panel and a method for driving the same. The present disclosure uses the anode and cathode layer of the OLED device as an electrode layer of the touch sensor. Thus, by performing the touching and displaying of the touch display in a time sharing manner, the electrode layer can be omitted, and the thinner touch display can be manufactured.
