Noritake VFD: Readability Part 1 - Viewing Angle

Noritake VFD: Readability Part 1 - Viewing Angle E-MTR-0001-00 http://www.noritake-elec.com Objective: To compare the difference in viewing angle between the VFD module and LCD Displays used: - VFD module: CU20025-UW1J http://www.noritake-elec.com/uversion... - LCD: HDM20216L Results: When rotating horizontally, LCD starts to gets harder to see around 45° and barely see anything on the LCD around 65°. VFD module had no problem reading the display content when rotating from side to side. When rotating down, LCD starts to gets harder to see around 30° and barely see anything on the LCD around 45°. Then rotating up, the LCD becomes harder to read from 40° to 45°. VFD module had no problem reading the display content when rotating up and down.
