Abstract
The present disclosure provides a touch display device including an organic light emitting diode (OLED) display panel and a touch layer. The OLED display panel includes a common cathode and a plurality of redundant cathodes. The common cathode and the plurality of redundant cathodes are located in a same conductive layer. The touch layer is disposed on a side of the OLED display panel. The touch layer includes a plurality of touch electrodes. Orthographic projections of the touch electrodes on the touch display device partially overlap orthographic projections of the plurality of redundant cathodes on the touch display device.
