There are nine differences between mobile phone resistance and capacitive touch screen

Touch screen type: according to different sensing methods, touch screen can be divided into four categories: resistance type, Capacitive Type, infrared type, and ultrasonic type. Among them, the current market prospect of Resistance Type and Capacitive Type is the most promising, and other technologies may be difficult to catch up with in the short term.
Difference between a resistive screen and a capacitive Screen
Resistive touch screens are commonly known as "soft screens" and are mostly used for mobile phones in Windows Mobile systems. capacitive touch screens are commonly known as "Hard screens", such as M8, M9, Nokia X6, HTC hd2, iPhone, new smart machines such as G1 and Moto use this screen quality. Resistance type is a two-layer insulating film, a layer of resistance, a layer can be considered as a pure conductor, press to make the two-layer film contact. Changes the resistance value potential.
The capacitive sensor senses the charge movement on the screen with your fingers. These charges come from the wires around the touch screen, and the IC analyzes the current location formed by the movement of the charge on its pins.
1. Indoor visual effect
The two are usually good.
Ii. Touch sensitivity
1. resistive touch screen: the screen layers must be in contact with pressure. You can use your fingers (even with gloves), nails, and pens to perform operations. Support pen touch is very important in the Asian market, where gesture and text recognition are valued.
2. capacitive touch screen: the most subtle contact from the surface of the electrified finger can also activate the capacitive sensing system at the bottom of the screen. Inactive objects, nails, and gloves are invalid. Handwriting Recognition is difficult.
Iii. Precision
1. resistive touch screen: The precision can reach at least a single display pixel, which can be seen when touched by a pen. It is easy for Handwriting Recognition and helps you operate on a small control element interface.
2. capacitive touch screen: the theoretical precision can reach several pixels, but the actual contact area is limited by the finger. This makes it difficult for users to accurately click targets smaller than 1cm2.
Iv. Cost
1. resistive touch screen: Very low.
2. capacitive touch screen: The capacitive screen prices of different manufacturers are 10% to 50% more expensive than the resistive screen. This extra cost does not matter to flagship products, but it may block medium-price mobile phones.
5. multi-touch feasibility
1. resistive touch screen: impossible, unless the resistance screen is reorganized and connected to the circuit of the machine.
2. capacitive touch screen: depending on the implementation method and software, it has been implemented on the G1 technical demonstration and iPhone. The 1.7t version of G1 can implement the multi-point touch feature of browsers.
Vi. Damage Resistance
1. resistive touch screen: the fundamental feature of a resistive screen determines that the top of the screen is soft and can be pressed down. This makes the screen very easy to produce scratches. Resistance screens require protective film and more frequent calibration. The advantage is that plastic-layer resistive touch screen devices are less vulnerable and less vulnerable.
2. capacitive touch screen: glass can be used for the outer layer. Although this will not be indestructible, and may be broken under a severe impact, but glass should be better suited to daily scratches and stains.
7. Clean
1. resistive touch screen: Because touch pens or nails can be used for operation, it is not easy to leave fingerprints, oil stains and bacteria on the screen.
2. capacitive touch screen: touch the screen with the entire finger, but the outer glass is easier to clean.
VIII. Environmental Adaptability
1. resistor touch screen: the specific value is unknown. However, there is evidence that the Nokia 5800 with a screen resistance can work properly at-15 °C to + 45 °C, and there is no requirement for humidity.
2. capacitive touch screen: a typical operating temperature ranges from 0 ° to 35 ° and requires at least 5% humidity (working principle limited ).
9. visible effect in the sun
1. resistive touch screen: Usually very bad. The extra screen layer reflects a lot of sunlight.
2. capacitive touch screen: still good.
