  • Publication number: 20250053039
    Abstract: An E-paper display panel including an E-paper display layer, a first substrate, a pixel array layer, a common electrode layer, and a driving circuit is provided. The first substrate is disposed at a first side of the E-paper display layer. The pixel array substrate is disposed between the first substrate and the E-paper display layer and includes touch electrodes and driving pixels arranged in an array. Each driving pixel includes a first pixel electrode and a second pixel electrode. The touch electrodes, the first pixel electrode, and the second pixel electrode are overlapped with each other. The common electrode layer is disposed at a second side of the E-paper display layer. The first side is opposite to the second side. The driving circuit is in signal communication with the common electrode layer and the pixel array layer. The touch electrodes are individually in signal communication with the driving circuit.
