The BlueLine displays are the latest craze on display market. Right now the first modules for pcb mounting are available. Just put it into pcb and solder. There are no srews, pin header or cable necessary. Soldered means mounted. This is the the blue-white optic for a 2x16 and a 4x20 together with a smart production method.
The new display EA DIP204B-4NLW is compatible to the yellow/green DIP-line from ELECTRONIC ASSEMBLY. For a 4x20 display with 3.73mm font size outline dimension are very small: just 75x27x10.8mm ! Thanks to the novel supertwist technology viewing angle is extreme and color is real nice blue. As a standard display meets industrial standard with -20..+70°C. No contrast adjustment is required. Power supply is 5V or 3.3V (single supply) and interface is 4-bit , 8-bit or serial. Some more displays with that style are available (2x16, 122x32, 128x64).
