How to choose a touch screen glove

1. How does a touch glove work

First, to understand how a touch glove works, you need to understand how touching a screen works. The touch screens on today's phones and tablets are basically capacitive and work based on the current induced by the body. The capacitor screen is a four-layer composite glass screen. On the innermost and middle interlayers of the screen, a layer of chemical coating ITO is applied, and on the outermost layer, a thin layer of silica glass is applied as a protective layer. The ITO coating, which leads four electrodes from each corner of the screen, is an important working surface of the capacitor screen, ensuring a good working environment for the shielding layer.

When we touch the capacitor screen with our fingers, due to the electric field in the human body, a coupling capacitor will be formed between our fingers and the ITO working face. On the working surface, because of the high frequency signal, there will be a small current on the working surface is absorbed by the finger. This current is respectively from the screen of the four corners of the outflow, and flow through the four corners of the current and the size of the four corners of the finger and the distance is proportional to the four corners, after the precise calculation of the mobile phone, you can get the specific position of the finger touch. To put it bluntly, your finger touching the screen creates an induced current, and this induced current makes the screen work.

The reason ordinary gloves can't work the screen is that they are made of thick insulating material, which causes the fingers to touch the screen too far away from the ITO coating to form capacitance and cause the screen to fail to work. Touch gloves, on the other hand, use conductive materials (such as fabric fibers containing metal) in the fingers, so there is still an effective capacitance between the finger tip and the screen, allowing charge and current to be transferred and the screen to function properly.

2. How to select touch screen gloves

1, wool fabric: the most accurate but not durable enough

The materials of touch screen gloves are mainly wool fabric and leather. Wool touch screen gloves are the most common kind, and the price is not expensive, which can be bought for a few tens of yuan. The way to realize touch control is to integrate conductive fabric on the fingertips. It's relatively accurate because it wraps around the palm of your hand, but disadvantages include pilling, lack of durability, and a single-layer design that doesn't keep you warm.

When shopping for touch screen gloves, we recommend looking at higher-priced, higher-quality models that incorporate a honeycomb touch point on the surface of the wool for better handling and warmth.

2, leather: the most beautiful but poor accuracy

Leather gloves are basically the most fashionable style and are relatively more windproof and warmer. Their disadvantage is also more obvious, is will make the fingers a lot of thick, unable to achieve accurate operations such as typing. That said, it's possible to swipe to unlock or dial a number using a leather touch-screen glove, but texting is best done via a voice assistant or dictation.

3, multi-functional: suitable for outdoor sports

Like skiing and other winter outdoor sports friends can consider multi-functional touch gloves, this kind of gloves are usually relatively large, the use of high-tech composite material, can achieve good wind proof, warm effect. But obviously, the precision isn't great. At this time, some styles with flexible design are more useful, such as the double-layer design of the finger cover, the inside of the conductive wool, the outside of the flexible cover can be put on or off, while realizing the needs of sports and mobile phone use.
