The difference between capacitive screen and resistive screen, which is better?
1, the working principle is different
Resistive screen is composed of upper and lower layers of transparent ITO film and acrylic cover. When the hand or pen and other touch pressure to the screen, the upper and lower layers of ITO can input and output current is different, so that the CPU can calculate the corresponding position.
Capacitive screen is composed of the human body, the top of the screen and the surface of the screen to form a coupling capacitance, and distributed in the four corners of the screen, when the user gives instructions on the corresponding changes will occur.
2, precision and sensitivity are different
Resistive screen precision is higher than capacitive screen, it only needs a very small pixel pressure will be very accurate positioning and recognition of the signal.
Capacitive screen also has its advantages, it is better than resistive screen in terms of sensitivity. We only need to finger contact with the screen surface can receive the signal in real time.
3, the user experience is different
Capacitive screen user experience effect than resistive screen to improve a new level, the effect is better.
4, the advantages and disadvantages of each
Resistive screen: it is the realization of the point positioning, the need for the existence of the screen pressure, so we need some external media, such as nails, metal and other hard items. Since the surface layer of the screen uses a soft material, such an operation will lead to screen damage; however, one advantage is that it is not afraid of falling and will not break.
Capacitive screen: its outer surface is a high strength conductive glass, this material is not easy to cause the screen scratching and, defacement; but it will be more likely to lead to screen rupture.
5, how to choose
Selection of resistive touch screen or capacitive screen, we need to consider from a number of dimensions, the principle of action of the product is different, resulting in different input methods; product transmittance, product resistance to EMI, product life, product design requirements, product cost control, product visual colour whether it affects the use of the product and other factors to consider.
WIWOTOUCH is a leading touch solution provider offering a full range of touch solutions tailored to different customer needs. We are at the forefront of a technological revolution in which touch technology is increasingly being integrated into mobile and consumer electronics devices, such as smartphones, tablets, industrial controls, medical devices, automotive control centres and more. Our core technology lies in projected capacitive (P-Cap) touch solutions, including glass-on-glass (G/G), glass-on-film (G/F), and glass-on-double-film (G/FF), which provide a versatile and intuitive user experience through multi-touch gestures with feather-light sensitivity, a key feature increasingly required by end users. We believe we are well positioned to benefit from the growing demand for touch solutions in different end markets.
