Common problems when choosing touch screen for industrial tablet computers
1. Why can't resistive touch screens achieve multi-touch like capacitive touch screens?
Resistive touch screens cannot achieve multi-touch because of their structure. The resistive touch screen is divided into two layers, separated by spacers in the middle. When the touch screen of the touch industrial tablet computer collides with each other, the current will have an impact. The chip calculates the data between the power and the current, evaluates which position on the screen is under pressure, and then responds. When two or more points are pressed at the same time, the pressure on the screen of the touch screen of the industrial tablet computer becomes unbalanced, resulting in an error in touch control.
2. Is capacitive screen better or resistive screen better?
When choosing the right touch screen, it is necessary to decide according to the application environment of the product, the application population and the product market. The selection between the capacitive touch screen and the resistive touch screen is usually determined by cost, accuracy, damage resistance, environmental adaptability, etc. Although the resistive touch screen is not as good as the capacitive touch screen in terms of light transmittance, its low cost and wide application environment have become the choice of many industrial tablet PC manufacturers.
3. Long life of capacitive screen or long life of resistive screen?
Any product has a life, whether it is a capacitive touch screen or a resistive touch screen will be used because of the number of times, years, environment and other decisions to use the length of the cycle. The resistive touch screen is not afraid of dust, water vapor and oil, and can be touched with any object. However, because the outer layer of the composite film is made of plastic, too much force or a sharp touch may damage the touch screen of an industrial tablet. Relatively speaking, the use cycle of the capacitive touch screen is longer than that of the resistive touch scre
