AI Technical Summary
Technical Problem
In organic light-emitting diode (OLED) panels, external light reflection reduces visibility and contrast, and iodine or phosphorus elements in the polarizer may corrode the ITO electrodes, causing short-circuit problems.
Method used
Dummy wiring is set on the display panel, and materials with a lower reduction potential than the touch electrodes, such as Mg, are used to block the diffusion of contaminant components in the polarizer and prevent the touch electrodes from short-circuiting.
Benefits of technology
It effectively prevents iodine and phosphorus elements in the polarizer from diffusing to the touch electrodes, avoiding electrode corrosion and short circuits, and improving the visibility and contrast of the display device.
