AI Technical Summary
Technical Problem
Existing display devices suffer from random pixel defects, which affect the display effect.
Method used
A ring design with dummy electrodes and common electrodes is adopted. By forming an opening area on the auxiliary electrode and electrically connecting it to the common electrode, the overlap area between the dummy electrodes and the common electrode is reduced. Combined with the ring arrangement of dummy electrodes, the dummy electrodes are kept out of sight.
Benefits of technology
It effectively reduces random pixel defects and improves the reliability and display quality of the display device.
