LED backlight
Simply linking the display and lighting opens up a wide range of combinations.
Note
Some displays require an additional backlight, such as transmissive displays, which include negative mode displays. On the other hand, other displays can be operated with a backlight but it is not essential, such as transflective displays. Positive mode displays can be transmissive or transflective. The reflective displays do not need lighting.
Reflective: reflective displays are operated without an additional backlight, as these reflect the incident light.
Transmissive: transmissive displays are translucent and therefore require an additional backlight.
Transflective: transflective displays are both reflective and transmissive, i.e. they can be operated both with and without a backlight.
Positive: the font colour is always black and the background is light (non-illuminated) on positive mode displays. With this display, the background can also be illuminated with a corresponding white or colour backlight.
Negative: negative mode displays require an additional backlight as this is responsible for the font colour. The background itself is black or blue, depending on the model.
For a better understanding of the differences, you can download a corresponding simulator program from the ''Datasheets & Downloads'' section, and use the program to simulate the display with and without a backlight.
