A novel lightweight yet rugged wireless handheld touch display can be used up to 50m from the Dolch FlexPAC PC.
A novel lightweight yet rugged wireless handheld touch display can be used up to 50m from the Dolch FlexPAC PC.
Weighing only 710g and measuring just 220 x 29.5 x 162mm, the display is truly portable.
In addition, it is sealed to IP54, has an operating temperature range of -20 to +60C, and is designed to withstand shock and vibration in accordance with military standards.
As such, the device will easily cope with most industrial environments and field applications.
Furthermore, the wireless display is also equipped with an RS232 port so that other serial devices can be connected as if they were being connected directly to the computer.
This means that scanners for barcodes or 2D machine-readable codes can be connected, as well as label printers or other peripheral devices.
At the heart of the device is the option of an 8.4in transflective daylight-readable display or an 8.4in transmissive display, both SVGA (800 x 600pixel) colour TFT displays with integrated touchscreens.
The lithium-ion battery pack provides up to 4h of continuous operation, or an AC/DC adapter can be used to give extended operating periods.
Dolch strategic partner, Panasonic, originally developed the wireless display for use with its own range of 'wearable' PCs.
Based on mutual agreement, Panasonic redesigned its software to operate with the Dolch range of rugged portable computers.
