Problems solved by technology

Specifically, the IC is set on the substrate by means of chip on Glass (the chip is set on the substrate). The COG has both the output pin of the Touch function and the pin of the LCD driver. This design increases the pins of the COG pin. number, increasing the difficulty of the Bonding process
In addition, the Touch function traces output from the COG and the LCD function traces output from the COG overlap in a large area in the Fanout (fan-shaped) area, which increases the coupling capacitance between the two traces and affects the LCD screen display quality and Touch sensitivity

Abstract

The invention discloses a touch control panel and a driving method thereof. A driving chip is arranged on a chip area of a non-display area, the driving chip comprises a plurality of pins, at least part of the pins in the pins are output a first driving signal used for controlling a pixel electrode and a second driving signal used for controlling a touch control sensor in a time-sharing mode, a plurality of wirings corresponding to the pins are arranged on a fan-shaped area, and the wirings are used for transmitting the first driving signal and the second driving signal. Through the mode, the touch control panel and the driving method thereof can reduce the difficulty of a bonding technique. Meanwhile, the coupling capacitance between the walking wires is reduced, and therefore the display quality and the touch control sensitivity of the touch control panel are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel and a driving method thereof. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) is currently the most widely used flat panel display, and has gradually been widely used in various electronic devices such as mobile phones, personal digital assistants (Personal Digital Assistant, PDA), digital cameras, and computers. With the development and progress of liquid crystal display technology, people have put forward higher requirements for the display quality and appearance design of liquid crystal displays, and low cost and narrow frame have become the goals pursued by people. [0003] Touch Technology (Touch Technology) has developed rapidly in recent years, and a variety of touch technologies have been put into mass production. In-cell touch (embedded touch) technology is favored by major panel manufacturers because of its high...
