The difference between resistive screen and capacitive screen

by:Toponetech     2021-10-25
Resistive touch screens are commonly known as 'soft screens' and are mostly used in mobile phones with Windows Mobile systems; capacitive touch screens are commonly known as 'hard screens1. Indoor visual effects Both are usually very good. 2. Touch sensitivity 1. Resistive touch screen: pressure is required to make contact with each layer of the screen. You can use your fingers (even if you wear gloves), nails, stylus, etc. to operate. Support for stylus is very important in the Asian market, where gesture and text recognition are valued. 2. Capacitive touch screen: A subtle touch from the surface of a charged finger can also activate the capacitive sensing system under the screen. Non-living objects, nails, and gloves are invalid. Handwriting recognition is more difficult. 3. Precision 1. Resistive touch screen: The precision is at least a single display pixel, which can be seen when using a stylus. It is convenient for handwriting recognition and helps to operate under the interface with small control elements. 2. Capacitive touch screen: The theoretical accuracy can reach a few pixels, but in practice it will be limited by the finger contact area. This makes it difficult for users to accurately click on targets smaller than 1cm2. 4. Cost 1. Resistive touch screen: very low price. 2. Capacitive touch screens: Capacitive screens from different manufacturers are 10% to 50% more expensive than resistive screens. This extra cost doesn't matter to flagship products, but it may discourage mid-priced phones. Fifth, the feasibility of multi-touch 1. Resistive touch screen: impossible, unless the circuit connection of the resistance screen and the machine is reorganized. 2. Capacitive touch screen: Depends on the implementation method and software, it has been implemented in the G1 technology demonstration and on the iPhone. The 1.7T version of G1 can already realize the multi-touch feature of the browser. 6. Damage resistance 1. Resistive touch screen: The fundamental characteristics of a resistive screen determine that its top is soft and needs to be able to be pressed down. This makes the screen very prone to scratches. Resistive screens require a protective film and relatively more frequent calibration. The advantage is that the resistive touch screen device using the plastic layer is generally less vulnerable to damage and less likely to be broken. 2. Capacitive touch screen: The outer layer can use glass. Although this is not indestructible and may shatter under severe impact, the glass is better for daily rubbing and staining. 7. Cleaning 1. Resistive touch screen: Since it can be operated with a stylus or nails, it is not easy to leave fingerprints, oil stains and bacteria on the screen. 2. Capacitive touch screen: Use your entire finger to touch, but the glass outer layer is easier to clean. 8. Environmental adaptability 1. Resistive touch screen: The specific value is unknown. However, there is evidence that the Nokia 5800 with a resistive screen can work normally at a temperature of -15°C to +45°C, and there is no requirement for humidity. 2. Capacitive touch screen: The typical operating temperature is between 0° and 35°, and at least 5% humidity is required (limited by the working principle)
