TOUCH DISPLAY DEVICE AND DISPLAY PANEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454604 titled 'TOUCH DISPLAY DEVICE AND DISPLAY PANEL
The present disclosure provides a display device and a display panel, with various layers and electrodes arranged in a specific configuration.
- The display panel includes a transistor on a substrate, with planarization layers, an anode electrode, a touch buffer layer, a touch electrode, a touch line, a bank, an emission layer, and a cathode electrode.
- The touch electrode overlaps with the anode electrode in a non-light emitting area, allowing for touch functionality.
- The touch line is connected to the touch electrode through a touch contact hole, enabling touch input.
- The bank covers the touch electrode and includes an opening for the light emitting area, ensuring proper display functionality.
- The emission layer and cathode electrode are sequentially disposed on the anode electrode, contributing to the overall display operation.
