| Selecting the Correct Touchscreen Monitor |
|
There are many benefits in choosing touch technology. Touch
technology provides a fast and intuitive interface for the user.
Touchscreens simplify customer interactions. Users do not have to
know how to use a computer, but simply touch the monitor to make
their choices. No keyboard is required, saving valuable space. Visit
the Touch Product Selector to choose the Planar touchscreen monitor
which best suits your needs.
Planar offers two touch
technologies: capacitive and resistive. Both have advantages and
disadvantages. The table below can help you choose the best
touchscreen monitor for your application. |
| SAW |
How it Works |
- Durable glass construction
- High optical clarity
- Activated by a finger, gloved hand, or soft tip stylus
- Moving liquids or condensation can cause false touches
- Solid contaminants create non-touch areas until removed
- Doesn't support drag or draw effectively

Resistive
|
How it
Works |
- Cost-effective solution
- Activated by any stylus
- Very accurate
- Low power requirements
- Liquids won't affect touchscreen performance
- Polyester surface can be damaged
- Lower endurance (35 million touches)
|
 |
| |
| Capacitive |
How it Works |
- Scratch resistant, durable surface
- High endurance (225 million touches)
- Very accurate
- Good optical clarity (88+% transmissivity)
- Liquids won't affect touchscreen performance
- Does not work with gloved fingers or stylus

Application |
Planar recommends: |
| People with gloved hands need to interact with the
touchscreen monitor. |
Resistive or SAW |
| I need a cost-effective monitor for my employees to
use. |
Resistive |
| The touchscreen needs to be accurate. |
Resistive, SAW,Capacitive |
| I need a monitor that will tolerate liquids on the
screen. |
Resistive or Capacitive |
| I need to install a monitor in an unattended
environment. |
SAW or Capacitive |
| I need the touchscreen monitor to be as bright
as possible. |
SAW or Capacitive |
| I need a monitor that will be durable and scratch
resistant. |
SAW or Capacitive |
| I need a monitor that will withstand high levels of
impact. |

| Technology Comparison |
| There is no perfect touchscreen
technology that will meet every application requirement and
choosing the right technology can be difficult. In addition to
resistive and capacitive there are several other touch
technologies which are available. Below is a list of the
common touch technologies along with a comparison of the
various features. |
