Description

Technical Field

[0001] This invention relates to the field of curved touch screen processing technology, specifically to an automatic alignment vacuum bonding device for high-precision curved touch screens. Background Technology

[0002] A touchscreen, also known as a touch panel or touch screen, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphical button on the screen is touched, the tactile feedback system drives various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. As a latest computer input device, the touchscreen is currently the simplest, most convenient, and most natural way for humans to interact with computers. It gives multimedia a brand-new look and is a highly attractive new multimedia interactive device. The greatest magic of the touchscreen is that it requires no learning; everyone can use it, a feature that neither keyboards nor mice can match. Touchscreens are mainly used in public information retrieval, leadership offices, industrial control, military command, video games, song and food ordering, multimedia teaching, and real estate pre-sales, among other fields.

[0003] Existing bonding devices do not perform well on curved touchscreens, which seriously affects the bonding process and thus the quality of the bonding. Furthermore, the bonding efficiency is low. Therefore, there is an urgent need to develop a high-precision automatic alignment vacuum bonding device for curved touchscreens to solve the above-mentioned technical problems.
