4-character dot matrix display

3 April 2013 Opto-Electronics

The new ELMM-457SURCB/A3 from Everlight Electronics is a through-hole dot matrix display driven by packaged IC. Each display can be directly interfaced with a microprocessor and the serial IC interface allows the display of 104 built-in characters and 24 custom user-defined characters in a 5x7 pixel format.

The programmable 4-digit alphanumeric module display has a height of 6,5 mm and is configured in a 140-dot 4x5x7 matrix. Its LED light sources emit brilliant red light of high luminous intensity and provides excellent reliability and readability even in bright ambient light.

The display’s design allows it to be customised for individual applications. Features common to all configurations include low power consumption, a 3,3 V operating voltage, a serial input and 128-character ASCII format that allows the display of upper and lower-case characters. Additional characteristics of this lead-free and RoHS compliant device include colour selection variety, convenient brightness controls and software controlled features.

Applications include white and brown goods like home appliances, set-top boxes, audio electronics and gaming equipment; industrial equipment displays for instrument panels for industrial controls and test equipment; digital readout displays on moving message panels and POS systems, and telecommunications, medical and fitness equipment.
