There are two smartphone technology of several technologies that are often used by touchscreen or tablet touchscreen smartphones sold in the market, namely Resistive and Capacitive. There are some differences that affect the function and the price of the devices using each of these technologies.
Device with a resistive screen is operated with compressed, because the resistive screen is composed of several layers. Can be pressed with your finger or a tool such as stylus or tablet pen. Resistive screen price is cheaper than the capacitive screen. Resistive screen is more accurate than the capacitive screen because the sensor works on the screen is pressed. This type of screen is well suited for handwriting recognition. Disadvantages of the resistive screen is not multi touch, pushed two places at once simultaneously.
Device with a capacitive screen is not working with pressed, the screen of this type rely on the sensor electrode conductors, such as the fingers of our hands. The screen is still good capacitive seen under the sun. Enough with the light touch can directly activate the screen. Capacitive screen has no effect if the condition is dirty screen, and supports multi-touch screen. Unfortunately the price of capacitive screens are more expensive.
The nature and characteristics of these two touchscreen technology affect the use and price, usually phone / tablet with capacitive screens are more expensive than resistive screens. Examples of devices with capacitive screens on the market is, Apple iPhone, Samsung S Galaxy, HTC Incredible and many more. While examples of phones that use resistive screen that is, the Nokia N97, HTC Tattoo, LG KP500 Cookie and others. Take a good phone specification if you want to buy it, sometimes the same type but a different series of different specifications of the screen, for example as tablets Huawei Ideos S7 103 and 105 series, 103 series 105 series screen resistive and capacitive screens.
