Mobile phone LCD screen points several types, which is the best

Mobile phone touch screen is divided into two kinds: the resistance screen and capacitance screen, at present most popular touch screen for lens screen, is flat resistance and mirror capacitance screen, nokia majority of resistive screen, the representative of the capacitive screen for the iphone.

Resistance touch screen commonly known as “soft screen”, and more for Windows Mobile system;

Capacitive touch screen commonly known as “hard” screen, such as the iPhone and G1 machine using this screen.

The comparison of resistive screen and capacitive screen

A, indoor visual effects Both are usually very good.

Second, the touch sensitivity

1, resistance touch screen: need contact pressure restore the screen, you can use the finger (even with gloves), nails, stylus, etc. Support the stylus in the Asian market is very important, where is the hand gestures and character recognition are important.

2, capacitive touch screen: the fingers from the charged surface of the slightest contact can also activate the bottom of the screen capacitance induction system. Inanimate objects, nails, gloves is invalid. Handwriting recognition more difficult.

Three, precision,

1, resistance touch screen: at least a single display pixel precision, when using a stylus. Convenience of handwriting recognition, helps in the use of small operating under control elements of the interface.

2, capacitive touch screen: theoretical precision can reach several pixels, but actually will be restricted by finger contact area. So that the user is difficult to precisely click the goal of less than 1 cm2.

Four, cost,

Touch screen: 1, resistance is very low.

2, capacitive touch screen, different vendors of capacitance screen than resistive touch your 10% to 50%.

Five, multi-touch feasibility

1, resistance touch screen: impossible, unless the reorganization of the resistive screen connected to the circuit of the machine.

2, capacitive touch screen: depends on the realization and the software, the most mainstream mobile phone have support for capacitive touch screen (except nokia)

Sixth, the loss of resistance

1, resistance touch screen: the root of the resistive screen features decided to the top of it is soft, and need to be able to press on. This makes the screen is very easy to scratch. Resistive screen protective film and relatively more frequent calibration. Beneficial aspect is that the resistance of the plastic layer touchscreen devices generally are less vulnerable, more is not easy to break.

2, capacitive touch screen: the outer glass can be used. So that while not indestructible, and may fracture under severe impact, but the glass to deal with daily scratches and blemishes.

Seven, clean

1, resistance touch screen: because you can use the stylus or nails, more is not easy to leave fingerprints, grease and bacteria on the screen.

2, capacitive touch screen: to use the finger to touch, but the outer glass clean more easily.

Eight, environmental adaptability

1, resistance touch screen: concrete numerical value is not clear. But there is evidence that the use of resistive touch can Nokia 5800-15 ° C to + 45 ° C temperature to work properly, the humidity is nothing.

2, capacitive touch screen: the typical operating temperature between 0 ° to 35 °, need at least 5% humidity limit (principle). Nine, visual effects in the sunlight

Resistance touch screen: usually bad, additional screen level reflects a lot of sunshine.
