EA LED36X28-GR LED illumination for EA DOGS104x, 33.5 x 12.5 mm, yellow-green /

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.
