Description

A capacitive touch display with large size and zero frame

technical field

The utility model relates to the technical field of capacitive display screens, in particular to a capacitive touch display screen with a large size and zero frame.

Background technique

The touch display allows the user to operate the host by lightly touching the icons or text on the display with his finger, which eliminates key operations and makes human-computer interaction more straightforward. Touch screens are mainly divided into three categories: capacitive touch screens, resistive touch screens and surface acoustic wave touch screens. The existing large-size capacitive touch display screen is shown in Figure 1, including a large-size capacitive screen body, an aluminum profile middle frame A, a liquid crystal display screen, a sheet metal bracket A, and a sheet metal rear cover A. The large-size capacitive screen body passes through The double-sided tape is pasted on the LCD screen. The left end of the sheet metal bracket A is connected to the LCD screen with screws and supports the LCD screen. The right end is fixed with the aluminum profile middle frame A with screws, and the aluminum profile middle frame A is fixed with screws. The liquid crystal display screen and the sheet metal rear cover A are fixedly connected to the sheet metal bracket A by screws. When assembling, it is necessary to first paste the large-size capacitive screen on the LCD display with double-sided adhesive tape. The pasting process can only be positioned by naked eyes, and it is difficult to locate accurately. When the LCD screens are positioned relative to each other, it is necessary to clean the dust between the two, which undoubtedly increases the difficulty of assembly. In addition, the large-size capacitive screen body and the LCD screen are pasted with double-sided adhesive tape, which is difficult to separate. Since these two components are the most valuable components, once a certain component is damaged, the two components cannot be separated and can only be replaced. , increasing the cost of after-sales maintenance. Since the width of the middle frame of the aluminum profile needs to be determined with the thickness of the liquid crystal display, the middle frame of the aluminum profile is very thick and the visual appearance is poor. The entire aluminum profile middle frame needs to be locked on the LCD screen through a sheet metal bracket, which requires that there must be mounting holes around the LCD screen, resulting in a very limited selection of LCD screens.
