AI Technical Summary
In existing touch panels, the arrangement of touch signal lines, pixel electrodes, and other functional electrodes is unreasonable, resulting in small touch area, low transmittance, poor touch accuracy and sensitivity, which affects the overall performance of the display panel.
A capacitor electrode is set in the sub-pixel region of the pixel unit, such that the overlap area between the capacitor electrode and the sub-pixel electrode is greater than the overlap area between the main pixel electrode and the common electrode in the main pixel region. The capacitance value is adjusted to improve the storage capacitor structure between electrodes and simplify the arrangement of touch signal lines.
It improves the touch accuracy and sensitivity of the touch display panel, simplifies wiring connections, and enhances the overall performance of the display panel.
