A brief history of the multi-touch screen industry

In a fast-paced, technology-driven world, multi-point capacitive touch screens have become an integral part of our daily lives. From smartphones and tablets to ATMs, kiosks and industrial machines to medical devices, touch screens have revolutionized the way we interact with technology. These multi-function interfaces have come a long way since their inception and have now evolved into powerful multi-point capacitive touch screens that offer unprecedented durability, sensitivity and versatility.

The development of touch screen technology can be traced back to the 1970s. Here's a brief history of the touchscreen industry:
1. Late 1970s to early 1980s: The first commercial touch screen is released. These touchscreens primarily use resistive technology, using a screen made of glass and a conductive layer to detect touches.
2. Mid-1980s: With the introduction of capacitive touch screen technology, the touch screen market began to boom. Capacitive touch screens use glass or plastic based on conductive materials to detect touches through changes in the charge of the object being touched.
3. Early to mid-1990s: Surface acoustic wave (SAW) and surface capacitance (SCT) technologies become mainstream. SAW technology detects touch by propagating sound waves across the screen surface, while SCT technology senses touch based on a glass surface coated with a conductive coating.
4. Early to mid-2000s: Emergence of optical touch screen technology. This technology uses a pattern of sensors to detect touch and can provide high resolution and multi-touch capabilities.
5. 2007: The release of Apple’s iPhone marked the full popularity of multi-point capacitive touch screens. The multi-point capacitive touch technology introduced by Apple has led the development of the smartphone and tablet markets.
6. 2010s: touchscreen technology develops further with the rise of wearable devices and large-size touchscreens. New technologies such as electromagnetic, infrared and projected touch screens are emerging.
7. Today: Touch screens have been widely used in various devices, including smartphones, tablets, computers, ATM machines, digital signature pads, vending machines, industrial control equipment, medical equipment, etc. New innovations such as flexible, transparent and inductive touch screens are also emerging and will further promote the development of the touch screen industry.

In general, the touch screen industry has experienced multiple technological changes and innovations. From the earliest resistive touch screens to today's multi-point capacitive touch screens, the technology continues to advance and the scope of applications becomes more and more extensive.
