Mobile touch screen technology

capacitive touchscreens

      Touchscreens are a type of screen that enables the user to interact with the mobile device directly by touching the screen. There are several different kinds of touchscreens, depending on the different methods of sensing touch that they have, but these three are the main types applied to mobile devices.

      Mobile touchscreen types

      • Resistive: These are the most widely used type of screens in mobile phones. They are resistant to water and dust, and you can touch them with a finger, a stylus, etc. However, they are not resistant to scratches, and what’s more, they become less efficient when they get one. They have a lifespan of about 35 milion touches.
      • Capacitive: More expensive than resistive screens, these are resistant to water, dust and scratches, and have a longer lifespan. However, you can only activate them with your fingers.
      • Infrared: The most expensive of these three types, these are however the most resistant kind. The only disadvantage is that they are activated with warmth; so if your fingers are frozen in the winter, there is a good chance you may not be able to activate your phone.

    • Touch screen types and lifespan

      The average lifespan of resistive touchscreens is of 35 milion clicks, and that of captitive touchscreens, of 225 milion clicks, whereas infrared touchscreens have an average lifespan of 7 years. Also, external factors like the light of sun or dirt may affect the good function of your touchscreen. In order to prevent this you can use a screen protector, which will keep your screen cleaner for longer, but it is always a good idea to clean it with a microfiber cloth from time to time. As for the battery, it depends on the mobile, but it is preferrable to adjust the screen light at 50%. This way, battery will last longer and so will your touchscreen.
