With the increasing popularity of personal computers, various new types of input machines have also been developed for the market. Let me introduce two different types of touch screens
Brushwork is mostly used for pictures or handwritten text with high accuracy requirements. Finger touch is used when stroke accuracy is not too high. Unlike the stylus, which has to be equipped with a special pen, the finger-touch can be input by touching the display panel directly with one's finger, which makes the distance between people and computers even closer. The brushstroke type includes electromagnetic induction type and static induction type, while the finger touch type includes capacity type, optical type, acoustic type, pressure detection type and MEMBRANE type.
Let's focus on the capacity formula
Capacity does not respond to pencil lead or gloved finger touch. The CRT display panel, for example, mostly USES electrodes directly on the panel, and more recently has been used as an input device for pocket or watch computers.
Projection capacitor (p-cap) touch control technology is the dominant technology in the industrial touch control field. PCAP technology is also widely used in a large number of mobile phones and tablet computers. Our innovative approach is driven by our compelling design capabilities, including a highly efficient infinite life cycle (achieved through an all-glass, destruction-proof surface), a fully planar design (without the use of grooves), and superior agility. Such functions are also attractive for industrial control applications. Sales in the consumer market can reduce costs but drive investment in research and development, thereby facilitating the implementation of functions, some of which also apply to industrial markets. Such as force recognition (z-axis detection) and gesture recognition.
