Abstract
An electroluminescent display touch panel includes a base substrate and an encapsulating substrate. The base substrate includes a pixel switching device, a readout device, an electroluminescent device, and a sensing pad. The pixel switching device and the electroluminescent device are disposed in a display region. The readout device and the sensing pad are disposed in a non-display region. The encapsulating substrate includes a first spacer, a sensing spacer, and a conductive layer. The first spacer is disposed on the surface of the encapsulating substrate facing the base substrate, maintaining a cell gap between the base substrate and the encapsulating substrate. The sensing spacer is disposed on the surface of the encapsulating substrate facing the base substrate and corresponding to the sensing pad. The conductive layer is formed on the surface of the sensing spacer facing the sensing pad.
