Focus on thin film switches!

What is capacitive inductive touch switch? According to the switching principle, there are resistive touch switches and capacitive touch film switches. Capacitive inductive touch switch < BR > In a variety of technologies, capacitive touch sensing technology has become the mainstream of touch sensing technology, in the key scheme, can bring the overall appearance of the product grade upgrade. < BR > Capacitive inductive touch switch can penetrate the insulation material shell more than 20mm (glass, plastic, etc.), accurately detect the effective touch of the finger, to ensure that the sensitivity, stability, reliability of the product will not change due to the change of environmental conditions or long-term use, and has waterproof and strong anti-interference ability. < BR > There are many types of multi-touch technology, but the following four are mature. 1. "LLP(Laser Light Plane) technology" mainly uses infrared laser equipment to project infrared light onto the screen. When the screen is blocked, infrared light is reflected, and a camera below the screen captures the reflection. After systematic analysis, we can make a response. < BR >2. "FTIR(CoolcoolingTotal Internal Reflection) Technology" will add LED light into the interlayer of the screen. When the user presses down on the screen, the light in the interlayer will cause different Reflection effects. To respond. ToughtLight technology uses projection to project infrared light onto the screen. Infrared light is reflected when the screen is blocked, and a camera below the screen captures the reflection. After systematic analysis can make a response. 4. Optical Touch technology, which has a lens at each end of the top of the screen to receive the user's gesture changes and the position of the Touch point. It's calculated and converted to coordinates and then reacted. Compared to conventional switches < BR > Capacitive inductive touch switch does not require human body to contact metal directly, which can completely eliminate safety risks. It can be used even with gloves, and is not affected by changes in human resistance in dry and humid weather, making it more convenient to use. No mechanical parts, no wear, unlimited life, reduced maintenance costs. The sensing part can be placed behind any insulating layer (usually glass or plastic), making it easy to create a keyboard that is sealed to its surroundings. < BR > Panel patterns can be arbitrary, the size and shape of the keys are arbitrary design, characters, trademarks, perspective window and other arbitrary collocation, beautiful appearance, fashion, do not fade, do not deformation, durable. Fundamentally solve all kinds of metal panels and mechanical panels can not achieve the effect. Its reliability and aesthetic design arbitrary, can directly replace the existing common panel (metal keyboard, film keyboard, conductive adhesive keyboard).
