How to distinguish from tablet capacitive sreen and resistive screen?
Now days capacitive screen and resistance screen widely used in tablet PC, so the question is, what is the difference between capacitive screen and resistive screen? Here to tell us about the distinguish between capacitive screen and resistive screen, which is better.
Resistive screen, called resistive touch screen, commonly known as "soft screen".
Capacitive screen structure is different, and only three, the innermost layer of glass, the outermost layer is a thin film, the film and the adjacent side of the glass is coated with ITO. Resistive screen is a sensor.
The difference between the capacitive screen and a resistive screen as follow:1. Difference between a capacitance screen and resistive screen: touch sensitivity comparison
Capacitive screen is to use the body's current sensing work, so any non-conductive objects such as nails, gloves and so can not be below the screen capacitive sensing system identified. Resistive screen is working through the pressure sensing using any items can touch, stylus support.
Capacitive multi-touch screen can be achieved, depending on the way to realize and use the software, now get implemented on the G1 and iPhone. The multi-touch resistive screen can not be achieved unless the resistive screen and connected to the machine restructuring circuit.
3. capacitive screen and resistance screen different three: Comparison of resistance to damage
The outermost layer of capacitive screen is silica glass protective layer, in severe shock is possible fragmentation. The outermost layer is a thin film resistive screen, you need to press down in order to reach a pressure sensor, resistive screen and stylus support, making the screen prone to scratches, needs protective film is relatively more frequent calibration, but more capacitive screen in terms of easy to break.
Capacitive screen can theoretically reach a few pixels, but in fact due to the limited contact area of a finger, making it difficult to accurately click on the target user's less than 1cm2. The accuracy of the resistance of at least a single display screen pixels can be seen when using the stylus. Facilitates handwriting recognition, helps operate under the use of small control element interface.
Capacitive screen and a resistive screen indoors visual effects are good, but in the outdoors, especially in the sunlight of visual effects has shown differences. Capacitive screen is better, but the resistive screen but because of the extra screen dimensions reflect sunlight makes the visual effect is poor.
To use the finger capacitive touch screen, easy to leave stains on the screen, but because of its outermost glass level, easier to clean. The resistive touch screen support, such as a stylus or fingernail to operate, easy on the screen dirty.
Capacitive screen typical operating temperatures between 0 ° to 35 °, at least 5% humidity. The operating temperature of the resistive screen is no specific number, but has proven resistive screen Nokia 5800 can be used in -15 ° C to + work at temperatures of 45 ° C, humidity resistance screen is also no requirement.
Expensive capacitive screen, capacitive screens from different manufacturers expensive than resistive screen about 10% to 50%, while the cheaper resistive screens currently on the market some cottage mostly resistive screen based.
