Description

Technical Field

[0001] The utility model relates to the field of a capacitive screen middle frame, in particular to a plastic middle frame which is convenient for laminating a capacitive screen. Background Art

[0002] Capacitive touch screens are made up of a series of capacitor components that form an electric potential gradient at the edge of the screen, allowing the capacitors between electronic circuits to interact with each other. When the capacitor components are touched, their capacitance value changes, thereby changing the gradient. The touch screen detects changes in the position of the capacitive touch screen by adjusting the gradient or eliminating the gradient.

[0003] During the assembly process of the capacitive screen, an outer frame needs to be installed on the outer wall of the capacitive screen for protection. The size of the outer frame is uniformly cast and manufactured, and there are rarely any errors. During the manufacturing process of the capacitive screen, a large piece of glass is cut and then processed, so it is inevitable that there will be small errors. This error will cause dust to penetrate into the outer frame through the gap during assembly, causing wear of the panel. This is also one of the reasons for the loss during the assembly process.
