Comparison of resistive screen and Capacitive Screen

Touch screen type: according to different sensing methods, touch screen can be divided into four categories: resistance type, Capacitive Type, infrared type, and ultrasonic type. Among them, the current market prospect of Resistance Type and Capacitive Type is the most promising, and other technologies may be difficult to catch up with in the short term. Difference between a resistive screen and a

ATMEL mxt224 capacitive touch screen debugging notes

After reading datasheet for four days, I finally started to write code yesterday. So far, the capacitive screens I have done include ITE, Solomon, focaltech, EETI, and cypress. To be honest, the driver for writing these things is already familiar, but today I still feel it! ATMEL's capacitive screen is the best. The interface for drivers is perfect, and even the object-oriented idea is used! The Atmel drive

Capacitive Touch Key principle

At this stage, with the capacitive touch button in appearance and service life and other aspects are superior to the traditional mechanical keys, capacitive touch keys are increasingly widely used in the field, including home appliances, consumer electronics, industrial control and mobile equipment. In this paper, a specific capacitive touch switch chip SJT5104 i

Capacitive screen Principle

Capacitive ScreenThe capacitive touch screen is a layer-4 composite glass screen, as shown in. The inner surface and interlayer of the glass screen are coated with an ITO conductive layer, and the outermost layer is only a 0.0015mm thick glass protective layer. The inner ITO layer is used as the shielding layer to ensure a good working environment. The inner layer Ito coating is used as the working layer fo

Fundamentals of driving the capacitive touch screen for Android platform

This address, reproduced please specify: http://blog.csdn.net/dearsq/article/details/51251009How Hardware WorksThe working principle of the touchscreen is to report the values of coordinate values, x-axis and y-axis. So the input subsystem is used in Linux to implement it.Specific hardware principles can refer to this article capacitive touch-screen hardware fundamentals.This paper mainly summarizes the driving principles and porting steps on Android

What's Force touch?

 What is Force Touch Force touch also into pressure feeling control, force feeling control, there is no uniform name, is Apple for its products Apple Watch, new MacBook and a new 13-inch MacBook Pro, a touching sensing technology. Through the Force touch, the device can perceive the intensity difference between the light pressure and the pressure, and bring up different corresponding functions. Force touch differs from previous multi-touch multi-touch techniques. Compared to the physical butto

12-inch new MacBook's force Touch usage tips Daquan

If you have more force Touch skills, you are welcome to share the comments with everyone, so that we can better and more fully play the Force Touch on the Macbook convenience and efficiency. Users who have Apple Watch on their hands have more knowledge of the Force Touch feature, or users who have purchased the new Macbook experience this feature. Force Touch is a touch sensing technology that Apple uses for Apple Watch, the new MacBook, and the new MacBook Pro. With Force Touch, the dev

JS development of multi-touch screen browser

This article describes a lot of mobile phone touch event knowledge, such as touchstart,touchmove,touchend, for the screen to get left and right with the web version of the same OH. I used to be less exposed to this knowledge, recently done a project only to find that the original with Event.pagex is not able to get the current position (on the phone). Need to use var touch = event.originalevent.touches[0]; Then Touch.pagex can get it in the phone. I'll share more of this in the future, and it's
