Resistive or Capacitive Touchscreen?


The appearance of the tablet version of the Sony S1 and S2 is still a rumor. But there's a leaked report that if the tablet is called Sony S2 P. Tablet

Tablet industry today is growing rapidly and the specialization of the products is very high. In addition to the technology developed by the producers of pills is very variable, with the advantages of different, although using the same hardware and software.


Sony is trying to be different, both technological and hardware devices and software on new tables. S2 tablet, or P is an obvious example, but using the Android operating system, which can be the same, but this tablet is a fundamental difference.


One of the most notable differences in the presence of these Tablet P is the existence of two screens with a size of 5.5 inches, respectively, the functions Berber. The first screen works as a keyboard, while the second screen is a netbook.


The development of smart phone technology is very fast at all, especially after the launch of Google's Android operating system Add to competition in the mobile phone operating system with touch-screen capabilities. Mobile phone manufacturers competing to produce a handheld device with touch-screen capabilities. If you decide to buy phones with touch screen or tablet to consider is the technology behind it.


There are two technologies of several technologies that are often used by touch screen or tablet touchscreen smartphones sold in the market, ie, 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 air, as the resistive screen is composed of several layers. You can press with your finger or a pen or pencil tool like Tablet PC. Price resistive screen 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 display is well suited for handwriting recognition. Disadvantages of the resistive screen is not multi touch, drove in two places at once simultaneously.

Device with a capacitive screen, not working with the display of this type are based on the sensor electrode conductors, such as fingers. The screen is still good capacitive seen under the sun. Enough with the touch of light can directly activate the screen. Capacitive screen has no effect if the condition is a dirty screen, and supports multi-touch display. Unfortunately, the price of capacitive screens are more expensive.

The nature and characteristics of these two display technologies affecting the use and affect the price, usually phone / tablet with capacitive screens are more expensive than resistive screens. Some examples of devices with capacitive screens on the market, Apple iPhone, Samsung S Galaxy, HTC and many more incredible. 


While examples of phones that use resistive screen, that is, the Nokia N97, HTC Tattoo, LG Cookie KP500, among others. Be rated good phone if you want to buy, sometimes the same type but a different set of different specifications of the screen, such as tablets Huawei Ideos S7 103 and 105 series, 103 series of 105 screens display series resistive and capacitive.
As quoted from Softpedia, Sunday (08/28/2011), P Tablet Tegra processors will be equipped with two dual-core processor-based SoC (system-on-chip), with up to 4 GB of storage. In addition, consumers will be given additional memory 2GB SD card is attached in these devices are free.

In addition, Sony is linked with a capacity of 512 MB ​​RAM, 0.2 megapixel webcam y. Dual-screen device has a lighter weight between tablets issued by Sony, which is 370 grams.

It is not known how much the price should be the tablet Sony dual-screen output, but something that is filtered by one of the Internet sites (Engadget) Tablet Sony says that if P is scheduled to start in September to be rolled 2011.
