Touch switch IC is an integrated circuit chip that controls the opening and closing of a circuit switch by touch. It can be applied to various electronic devices, such as smart phones, tablets, televisions, lights, etc. The principle of touch switch IC is to realize touch control through capacitive induction principle.
Difference between touch switch and voice switch ic Touch delay switch When used, as long as you touch the electrode with your finger, the light will be lit, and the delay will be automatically extinguished after about 1 minute. It can directly replace the ordinary switch, without changing the indoor wiring.
Touch delay switch circuit dotted right side is the general lighting circuit, the left part is the electronic switch part. VD1~VDVS constitutes the main circuit of the switch, and IC constitutes the switch control circuit. Usually, VS is in the off state and the light is not on.
Working principle: The internal installation of the electronic touch IC and the lamp at the touch of the electrode to form a control loop.
Touch delay switch circuit dotted right side is the general lighting circuit, the left part is the electronic switch part. VD1 ~ VDVS constitutes the main circuit of the switch, and IC constitutes the switch control circuit. Normally, VS is in the off state, lightIt is used to control various operations on the touch screen. Touch screens have become an integral part of modern technology, especially in electronic devices such as phones, tablets and televisions.
3, touch chip refers to single point or multi-touch technology, the application range is mobile phones, computers and so on.
Touch screen IC refers to the touch screen control chip, which is a chip based on the principle of capacitive induction. It is mainly used to convert the capacitive signal generated by human contact on the touch screen and convert itFor the digital signal output to the processor, so as to achieve the control of the touch screen.
And the smartphone touch IC, in fact, is to deal with the touch operation of the IC, the touch screen function area is a piece of conductive glass with impedance, the line is gathered in a piece, through the FPC connection, the general touch IC are on the FPC, but there are some are directly done on the mobile phone motherboard.
TP: touch pad, touch screen IC: integrated circuit, G G: glass glass, glass on glass ITO: (Indium Tin Oxides) as nano indium tin oxides metal: metal, other meaning is not known.
Apple IC touch is a touch technology developed by Apple, which can sense the user's finger operations such as tapping, sliding, kneading and rotating, and convert them into electrical signals for processing.
1. After inquiry, the output voltage of LN8K05 touch chip is 3 volts to 5 voltsThe LN8K05 touch chip is a very good chip and is loved by people in the industry.
2, the two capacitors are in parallel, in parallel between the chip power pin and the ground pin.
3, positive. When the ln8k15 power chip works, the VDD pin of the chip connects a capacitor to the ground. The output voltage of the ln8k15 is positive, and a resistor is positive to the input voltage. During power-on, the input voltage charges the capacitor through the resistor.
4, according to the query of relevant informationThe power chip ln8k05 can not be replaced with other models, can only be replaced with their own models, the power conversion and recognition of different chips are not the same, so it can not be replaced with other models.
3, multi-touch technology touch chip basically uses the following four multi-touch technology: "LLP (laser light plane) technology", mainly uses infrared laser equipment to project infrared onto the screen. When the screen is blocked, infrared rays are reflected, and the camera under the screen captures where the reflection is going.
4, the main working principle of touch IC is capacitanceTouch technology. It detects and responds to the user's finger touch by adding a transparent capacitor layer to the touch screen.
5, the working principle of the capacitive touch screen is to sense the current of the human body can be operated, to avoid the touch of other items, in dustproof, waterproof, wear-resistant performance is better, capacitive touch screen has a long life and does not require pressure to produce signals, direct touch can be achieved. Resistive touch screen is mainly controlled by pressure sensing.
