... SCDV5540, SCDV5541, SCDV5542, SCDV5543, SCDV5544 Operation of the SCDV554X The SCDV554X display consists of a CMOS IC containing control logic and drivers for four characters. These components are assembled in a compact plastic package. Individual LED dot addressablity allows the user great freedom in creating special characters or mini-icons. The User Definable Character Set Examples illustrate 200 different character and sym- bol possibilities ...

... SCDV5540, SCDV5541, SCDV5542, SCDV5543, SCDV5544 Optical Considerations The 3.2 mm (0.123") high character of the SCDV554X gives read- ability up to five feet. Proper filter selection enhances readability over this distance. Using filters emphasizes the contrast ratio between a lit LED and the character background. This will increase the discrimination of different characters ...
