Description

Technical Field

[0001] The utility model relates to the technical field of touch panels, and in particular to a touch drive device and a display panel. Background Art

[0002] A panel including multiple sensor electrodes for sensing the approach or touch of an object is generally referred to as a touch panel. Such a touch panel can be completely separated from a panel member for displaying an image according to the shape of the touch panel. However, in recent years, since the touch panel is coupled to the panel member in an integrated manner, the touch panel is sometimes referred to as a panel without being distinguished from the panel member. In the following description, it can be understood that the panel includes multiple sensor electrodes for sensing the approach or touch of an object. At the same time, the approach or touch of the object to the panel can be detected by a touch driving device that drives this panel. The touch driving device supplies a driving voltage to the panel and receives a response signal to the driving voltage to detect the approach or touch of the object to the panel.

[0003] For example, the patent document with application number 202211189733.5 discloses a touch drive device and a display device including the touch drive device, and more specifically, relates to a touch drive device including a panel divided into one or more separate areas and setting the touch sensitivity of the corresponding areas in different ways to prevent errors caused by user mistakes, a display device including the touch drive device, and a touch management method.

[0004] Traditionally, the touch drive device and the panel are directly welded together, so when any one of them is damaged, they need to be replaced as a whole, which wastes resources. Therefore, it is urgent to design a touch drive device and a display panel to solve the above problems. Utility Model Content
