There are many ways to touch industrial custom capacitive touchscreen panel, so how do companies choose the most suitable way for them? Today we are going to understand the difference between various touch methods, and what are their advantages and disadvantages. Only by choosing products with better cost performance. Today I will show you the difference between capacitive and resistive screens?
Capacitive touch screens are more expensive. Capacitive touch screens from different manufacturers are about 10% to 50% more expensive than resistive touch screens, while resistive touch screens are cheaper.
Industrial capacitive touch screens consume more power than resistive touch screens.
Both the capacitive touch screen and the resistive touch screen have good indoor visual effects. But outdoors, especially under sunlight, the visual effects are obviously different. The capacitive touch screen works well. But the resistive touch screen reflects sunlight because of the extra screen layer. Makes the visual effect poor.
The multi-touch of the capacitive touch screen is achievable. It depends on the method of implementation and the software used. Has been achieved. The multi-touch of the resistive touch screen cannot be realized.
The capacitive touch screen works by using the current induction of the human body. Therefore, any non-conductive materials such as nails, gloves, etc. cannot be recognized by the capacitive sensing system under the screen. The resistive touch screen works through a pressure sensor. You need to use any object to touch it. And it can also support a stylus.
The outermost layer of the capacitive touch screen is a protective layer of silica glass. It may break under severe impact. The outermost layer of the resistive screen is a thin film, which needs to be pressed down for pressure sensing. Moreover, the resistive screen supports a stylus, which makes the screen prone to scratches. A protective film and relatively more frequent calibration are required. But it is not easy to break than the capacitive screen.
We need to use fingers to touch capacitive touch screens. It is easy to leave stains on the screen. But since the outermost layer is a glass layer, it is easy to clean. The resistive touch screen supports operations such as stylus and nails. So it is not easy to stain the screen.
The capacitive touch screen can theoretically reach several pixels. But in fact, it is limited by the area of finger contact. It makes it difficult for us to accurately click on targets smaller than 1cm. The accuracy of the resistive touch screen is at least as high as a single display pixel. It can be seen when using a stylus. It is convenient for handwriting recognition and helps to operate under the interface with small control elements.
The operating temperature of the capacitive touch screen is between 0°C and 35°C and requires at least 5% humidity. There is no specific value for the operating temperature of the resistive touch screen. However, it has been confirmed that the resistive screen can work normally at a temperature of -15°C to 45°C. The resistive touch screen has no requirements for humidity.
1.If the industrial touch screen only uses basic functions. You should use the resistive touch screen . Because the cost of resistive touch screen is lower;
2.If the industrial touch screen will often hit it during use. Should choose resistive touch screen. Because the capacitive touch screen is easily broken under impact;
3.If the working temperature of the industrial touch screen fluctuates greatly, it exceeds 00-350. Should choose resistive touch screen. Because the operating temperature of the capacitive touch screen is 00-350. Capacitive screens beyond this range do not work well. The operating temperature range of resistive touch screens is relatively wide;
4.If the industrial touch screen needs to use multi-touch function. You should select the capacitive touch screen. Because the resistive touch screen currently cannot support this function;
5.If the industrial touch screen needs a longer standby time. You should choose an electric touch resistive screen, because capacitive touch screens consume more power than touch resistive screens.
6.If the industrial touch screen needs to use a stylus. Should choose resistive touch screen. The capacitive touch screen does not support stylus due to the working principle of the capacitive touch screen;
7.If the working environment of the industrial touch screen is relatively dry. Should choose resistive touch screen. Because the capacitive touch screen has humidity requirements for the working environment. The resistive touch screen does not;
8.If you often use industrial displays in sunlight. Should choose electric touch capacity screen. Because the resistive screen reflects in the sun and affects its use.
