1. Why can't resistive touch screen achieve multi-touch control in the same way as capacitive touch screen?
Resistive touch screens do not allow for multi-touch, which is due to their structural resolution. The resistive touch screen is divided into two layers, separated by a barrier in the center. When the two layers collide with each other when touching the touch screen of an industrial tablet, the current will be affected, and the chip calculates the data between the force and the current, identifies the pressure at which position of the screen, and reacts. When two or more points are pressed at the same time, the pressure on the screen of the touch screen of the industrial tablet PC becomes unbalanced, resulting in touch errors.
2. Is it better to have a capacitive screen or a resistive screen?
When choosing the right touch screen, the demand is determined according to the use environment of the product, the user group and the product market. Usually through the cost, accuracy, damage resistance, environmental adaptability and other aspects to determine the choice in capacitive touch screen and resistive touch screen. Although the resistive touch screen is inferior to the capacitive touch screen in terms of light transmittance, it has become the first choice of many industrial tablet PC manufacturers due to its low cost and wide application environment.
3. Is the capacitive screen long life or the resistive screen long life?
Any product has a lifespan, whether it is a capacitive touch screen or a resistive touch screen, it will determine the length of the service cycle due to the number of uses, years, environment, etc. The resistive touch screen is not afraid of dust, moisture and oil and can be touched with any object. However, due to the plastic outer layer of the composite film, too much force or the use of sharp touches may cause damage to the touch screen of the industrial tablet PC. Comparatively speaking, the service life of capacitive touch screen is longer than that of resistive touch screen.
