  • 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.

  • Patent number: 12159598
    Abstract: An e-paper display apparatus includes an e-paper display panel including multiple source lines, multiple gate selection lines, and multiple pixel circuits and a driver circuit coupled to the e-paper display panel and configured to output a driving signal to the gate selection line. The gate selection lines and the source lines are disposed along a first direction. The source lines corresponding to the gate selection line simultaneously receive respective data signals when the gate selection line is turned on. The driving signal includes a first period and a second period. The gate selection line is turned on during the first period, and the gate selection line is turned off during the second period. A time length of the first period is greater than a time length of the second period.

  • Publication number: 20240321901
    Abstract: A display device includes an array substrate and a driving circuit. The array substrate includes active elements, a first scan line, a second scan line, a third scan line disposed between the first scan line and the second scan line, and a first selection line electrically connected to the first scan line and the second scan line. The active elements include a first active element and a second active element electrically connected to the first scan line, and a third active element and a fourth active element electrically connected to the second scan line. The driving circuit provides a first scan signal transmitted to the first scan line and the second scan line through the first selection line to control the first active element, the second active element, the third active element and the fourth active element.
