Kno, the world's first 14 inch "dual-screen" tablet, will be available at the end of this month. It is pre-installed with the Ubuntu system and has a very beautiful GUI. Kno has two versions. One is a dual-screen version with two 14.1 inch screens, which is similar to a book, and the other is a traditional single-screen version with only one 14.1 inch display, their retail prices are respectively 899 and 599 USD. In September this year, Kno presented a dual-screen tablet with two 14.1 inch

With the development of mobile networks, which can support more and more complex applications,Web developers need a way to handle these events. For example, almost all fast-paced games require th

Most of the interaction of mobile devices is achieved by touching touch, because mobile devices typically have a capacitive touchscreen (capacitive touch-sensitive screen) to capture the interaction of the user's finger. For touch-screen interactive websites, games, touch events are quite important. Apple introduced touch event api,android in iOS 2.0 and is catching up to this fact standard to narrow the ga

suddenly become transparent, the light transmittance is 80%, and the light transmittance decreases when the light transmittance goes down,To 300, the thickness increased to 80%. Ito is the main material used by the touch screen and capacitive touch screen of all resistor technology. In fact, the working face of the touch screen of resistor and Capacitive technology is Ito coating.② Nickel-gold coating, the

Q: If the input signal is systematically referenced, must the capacitive coupling be added? I am actually testing, either positive, inverting input, operation is not working.A: The capacitive coupling is isolated from the DC component, and the non-work may be caused by no static working point. AC Signal amplification Circuit or audio amplification circuit, you can also use a power bias circuit, the static D

"touch down action" is detected, a white four-sided line is drawn in the application's view. A view in Android exposes an interface to access graphical layouts and draw surfaces. The following discussion is based on this usage scenario.System Delay Overview Analyze touch ecosystems with time series detailsIn the Android system, it usually represents the entire system delay. The value is measured in the Android version of the Jelly Bean. In the next article in the Touch series we will explain ho

many consumer electronic display products, touch technology has also completed the transition from resistive touch to capacitive touch control. As one of the key materials of capacitive touch screen, the cover glass has irreplaceable status, especially high aluminum cover glass, high growth rate and excellent market prospect in 2016. In addition, color filter, polarizer, ITO, liquid crystal materials, such

ObjectiveIf we allow users to control the Web APP in a way that is similar to a desktop browser mouse gesture on the page, there must be a lot of clickable areas on this page, what if the user touches those clickable areas??Mobile devices such as smartphones and tablets typically have a capacitive touchscreen (capacitive touch-sensitive screen) to capture the interaction of the user's finger.

the user experience will also decrease. From seller selection to coupon printing, at least 30 seconds or even several minutes. Generally, non-computer users are not very familiar with this system. In addition, for large screen touch screen, most of the use of infrared touch screen, the touch screen response speed and touch effect is far less than the capacitive touch screen effect (I-PHONE, I-PAD are using capaci
