TOUCHSCREEN DISPLAYS

4.3″ SLCD-N43H Resistive

Part Number: 51-0711-001

5.7‑inch SLCD5E high‑resolution VGA resistive touchscreen

4.3″ SLCD-N43H Resistive Touchscreen Display

Our modules provide a fully integrated display solution, combining the LCD, controller board, backlight driver, and touchscreen into a single assembly to simplify system integration. Custom variants are available upon request to meet specific mechanical, optical, or interface requirements.

Powered by the SLCD-N43 controller:

Resistive Touchscreen, with horizontal mounting
Two serial ports for either RS-232 or 3.3V CMOS. One port can be converted to RS-422 as a manufacturing option.
266 MHz ARM9 Processor. 28MB highly reliable NOR data Flash for user downloadable bitmaps with optional RLE compression.

This 4.3″ module features:

Comes with a VGA (640×480) display.
Designed for long-term availability with a 10+ year processor life and a multi-sourced, industry standard LCD form factor.
ESD and EMC results available to ease regulatory compliance testing.
