Touch Panel Display
The 3.5 inch 1/4 VGA (Video Graphic Array) display is a 262-, 144-color, transflective LCD (Liquid Crystal Display)
in TFT (Thin Film Transistor) color with a 240 x 320 resolution. The LCD is covered by an industrial touch screen
lens for maximum durability and backlit for maximum viewability; see
Hand Held Products recommends using a screen protector with the touch panel. Screen protectors help prevent
wear and damage and also protect the touch panel; especially when used with applications that require high-volume
interfacing with the touch panel. We expect users to replace the screen protector at regular intervals when the
screen protector is becoming worn or punctured.
For touch panel input, use the stylus included with the terminal or your finger. The method you choose depends on
which one is most appropriate for your application. While there is a great deal of variation in different applications,
use of the supplied stylus provides greater touch screen accuracy; see
!
Use of objects, such as paper clips, pencils, or ink pens on the touch screen can damage the touch panel
and will void the warranty.
