Description

Technical Field

[0001] This utility model mainly relates to the field of touch layer of display module, and specifically to an anti-interference enhancement structure for touch layer of display module. Background Technology

[0002] With the rapid development of information technology, touchscreens, as the core interface for human-computer interaction, have been widely used in various electronic devices such as smartphones, tablets, laptops, automotive displays, industrial control equipment, and smart homes. Capacitive touchscreens, due to their high sensitivity, long lifespan, and excellent user experience, have become the mainstream technology in the current market.

[0003] The core functional layer of a capacitive touchscreen is the touch sensing layer, which is typically composed of an electrode array made of transparent conductive materials (such as ITO, silver nanowires, metal mesh, etc.). This layer is responsible for detecting the capacitance changes caused when a user's finger or stylus approaches or touches the screen surface, thereby determining the touch location.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] The high-frequency, high-voltage pulse noise generated when the display panel (especially the backlight inverter and row / column drive signals of the LCD) is working makes the touch sensing layer extremely susceptible to various electromagnetic interferences (EMI) and noises in the module's internal and external environments during operation (especially at high refresh rates or high resolutions), affecting the normal operation of the touch layer.
