Abstract
The invention provides a touch display panel and an electronic device, with the positions of pixel electrode layer and common electrode layer at the side of array substrate in conventional touch display panel changed; wherein common electrode layer () as touch sensor is changed to the top, and pixel electrode layer () is changed to below common electrode layer (). Pixel electrode () is connected to source/drain () of TFT () via first through hole (V) penetrating planarization layer (), which requiring only to drill planarization layer without the need to drill both the protective layer and planarization layer as in prior art to achieve connecting pixel electrode to TFT. The invention saves a mask, a drilling process and production cost and improves production efficiency. Moreover, placing common electrode () as touch sensor at the top facilitates optimizing sensitivity and SNR, thereby improves touch performance and product quality.
