A smart touch screen that can be seamlessly spliced

Abstract

The invention discloses an intelligent touch screen that can be spliced ​​seamlessly, comprising a glass cover plate, a capacitive touch screen, a PET base film, a display screen, a protection plate, a stable bottom plate and a side fixing plate, the glass cover plate, the capacitive touch screen , PET base film and display screen are arranged sequentially from top to bottom. In this device, the glass cover plates are bonded to each other through matching arc-shaped bonding surfaces, and are bonded by special glue. The curved bonding surfaces are aligned from left to right The cut semicircle structure avoids the intersection of straight lines and the occurrence of Moiré fringes, and improves the seamless connection and display effect of the smart touch screen. It ensures that the touch screen will not shake left and right, and displacement deviation is not easy to occur. The limit column and limit ring are fixed between the protective plate and the stable bottom plate, which ensures that the spliced ​​protective plates are not easy to shake, and further increases the device. The stability is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of intelligent touch screens, in particular to an intelligent touch screen that can be seamlessly spliced. Background technique [0002] Smart touch screen technology uses the current induction of the human body to work. The smart touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. electrodes, and the inner layer of ITO is the shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the electric field of the human body, a coupling capacitance is formed between the user and the surface of the touch screen. For high-frequency currents, the capacitance is a direct conductor, so the finger absorbs a small current from the contact point. This curren...

AI Technical Summary

Problems solved by technology

[0003] 1. Existing smart touch screens are individually designed to be too large for transportation and production, and installation and disassembly are inconvenient, so smart touch screens are often composed of multiple small-sized capacitive screens spliced ​​together, and the connections between them often have large gaps , the effect similar to seamless splicing cannot be achieved, and the visual effect is poor;

[0004] 2. The existing smart touch screen is easy to shake between the touch screens during the installation and splicing process, and the installation structure is unstable and inconvenient to disassemble
