Touch Screen Display
The display is a 3.5” TFT transmissive, 65k color LCD display with a backlight, QVGA (240 x
320 resolution); see Display Backlight on page 3-3. The touch panel is a 4-wire analog
resistive touch.
Optimus 5900 RFID terminals ship with a screen protector already installed over the
touch screen lens to help prevent damage to the touch screen. Do NOT remove this
screen protector before initial use. Honeywell recommends using screen protectors,
especially for applications that require high volume interfacing with the touch screen. For
more information, see Using Screen Protectors on page 3-3. You can purchase additional
screen protectors by contacting your Honeywell sales representative.
For touch screen 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, you generally achieve greater accuracy with the
stylus for buttons or icons that are close together.
