AI Technical Summary
Technical Problem
Existing integrated driver chips have a large number of pins in small and medium-sized products, resulting in a large chip size.
Method used
By designing first and second electrode channels in the display panel, and sharing the first touch pin with the first and third line groups, and sharing the second touch pin with the second and fourth line groups, the number of touch pins on the driver chip is reduced.
Benefits of technology
This effectively reduces the size of the driver chip, lowers the lead impedance, and improves the accuracy and sensitivity of the touch signal.

Abstract
本申请提供一种显示面板，包括形成第一电极通道的多个第一触控电极、第一引线、第二引线和驱动芯片。驱动芯片位于多个第一电极通道在第一方向的一侧，驱动芯片包括显示驱动引脚、第一触控引脚和第二触控引脚，第一触控引脚和第二触控引脚分别位于显示驱动引脚在第二方向的相对两侧。第一电极通道包括在第一方向相邻的第一通道组和第二通道组，第一引线包括与第一通道组连接的第一线组和与第二通道组连接的第二线组，第二引线包括与第一通道组连接的第三线组和与第二通道组连接的第四线组。第一线组和第三线组均连接到第一触控引脚，第二线组和第四线组均连接到第二触控引脚。因此，可以减少驱动芯片上触控引脚的数量，进而减小驱动芯片的尺寸。
