Problems solved by technology

Therefore, the vertical electrodes and horizontal electrodes located near the cut corners will be partially cut off in order to match the cut corner design, which will reduce the capacitance generated in the cut corner area, thereby affecting the touch sensitivity of the cut corner area.

Abstract

The invention relates to the technical field of touch and provides a touch panel. The touch panel is provided with at least one non-rectangular corner area at corners of the touch panel. The touch panel comprises a first electrode and a second electrode which are intersected and electrically insulated. The first electrode comprises a plurality of first strip electrodes extending along a first direction. The second electrode extends along a second direction and comprises a plurality of strip electrodes and at least one auxiliary electrode. The auxiliary electrodes are arranged in the one non-rectangular corner areas, form included angles smaller than 90 degrees with the second direction and are electrically connected with at least one adjacent second strip electrode. The touch panel has the advantage that touch sensitivity of the non-rectangular corner area of the touch panel is improved.

Description

Technical field [0001] The invention relates to an input interface, especially a touch panel. Background technique [0002] In recent years, there have been more and more application products that combine touch functions and displays to form touch display panels, including mobile phones, GPS navigator systems, tablet PCs, and personal computers. Digital assistants (PDA) and laptop computers (laptop PC), etc. At present, the technological development of touch panels is very diverse, and the more common technologies include resistive, capacitive, and optical. Among them, capacitive touch panels have become the mainstream touch technology used in mid-to-high-end consumer touch electronic products due to their high accuracy, multi-touch, high durability, and high touch resolution. [0003] Capacitive touch panels are generally divided into self-capacitive and mutual-capacitive (also called projected capacitive). Mutual-capacitive touch panels generally have vertical electrodes and h...
