Comparison Between Resistive And Capacitive Touch Screen

Rugged LCD monitors provide highly responsive touch screens for high-quality interaction between operators and automated machines.There are two kinds of touch screen LCD monitor function to choose from, resistive and capacitive touch.

Resistive Touch LCD Monitor

Resistive touch screen displays consist of several thin layers. It works by applying pressure to the outer layer, pushing it to the next layer, allowing the display to sense the pressure and record the input. Resistive touches allow input objects such as fingers, nails, stylus, or gloves. In order to improve durability, reliability and service life, common touch screen displays in resistive touch screen LCD attached PET film (polyester film). PET film is a kind of high performance, transparent thermoplastic, low moisture absorption, UV resistance, high tensile strength. As a result, heavy industries like mining, heavy transportation, or agriculture prefer resistive rather than capacitive touch screens.

Advantages of resistive touch screen

  • Low cost
  • Works well at different angles
  • Less chance of accidental touch
  • Can sense any object if touched with adequate pressure
  • Higher sensor resolution

Disadvantages of resistive touch screen

  • Cannot respond to multi-touch sensing
  • Less sensitive and so need some pressure to be applied for it to work
  • Thick top layer results in lower clarity of display
  • The screen is more easily scratched or damaged
  • Will not work if there is a small crack on the screen

Capacitive Touch LCD Monitor

A capacitive touch screen display monitor utilizes electrical conductivity instead of pressure to detect input. Capacitive touch screens sense conductive properties, such as a fingertip or conductive gloves. Using conductivity to detect touch increases responsiveness and sensitivity, allowing up to 10 register touch points and gestures, thus providing more options for users based on different industrial applications, like zoom, pinch, or multi-touch. Capacitive touch screens have been widely used in industrial deployments where they are suitable for highly sensitive touch screens for a better end-user experience.

Advantages of capacitive touch screen

  • Durability
  • Better display
  • Easy to use
  • Supports customization
  • More sensitive to touch
  • Offers multi-touch sensing functions
  • Ease of cleaning

Disadvantages of capacitive touch screen

  • Costlier than resistive touch screen
  • Highly sensitive means it can be activated at the lightest of touch – may lead to accidental touch
  • Views are best from the front
