More and more industrial equipment choose to use TFT colour screen+touch screen display program(3.5inch 4.3inch 5inch 7inch 10.1inch 15.6inch etc are more commonly used, the user manster control support, then you can directly choose the RGB interface screen+4 lines of resistive touch screen, if only ordinary microcontroller system can choose to clear up the photoelectricity comes with RA8875 master control of colour with touch screen module), then industrial equipment choose what are the advantage of resistive touch screen.
1. Low production cost: resistive touch screen due to the simple structure, production is relatively easy, compared with other LCD display touch technology, the cost is lower.
2. Any object can be activated: as mentioned above, any object that can exert pressure on a resistive touch screen will trigger a touch action and be detected by the ressitive touch sensor. Whereas in industrial and medical environments, operators may use gloves on LCD touchscreens, this feature of resistive touchscreens make them a btter choice for the above industries.
3. Insensitive to stray stimuli: the way resistive touchscreen detect touch movements dictates that liquid spills/snow or surface contaminants will not case the touchscreen to react unexpectedly. And for industrial and outdoor environments these are very important.
4. No risk of glass breakage: most lcd touch screen technology use glass as the outer layer of touch. This is not normally allowed in food and beverage facilites to avoid shattered glass contaminating the food. Resistive touchscreen use a tough polycarbonate outer layer that can contain broken glass in the event of an LCD screen breakage.
5. Low power consumption: resistive touchscreen do not consume much power.
6. Insensitive to EMI/RFI: resistive touchscreens detect changes in ressitance to position the coordinates of the touch. This is not sensitive to EMI/RFI and is very suitable for all types of industrial control equipment.
