The brightness of an optical module is specified as the amount of light, in lumens, that is emitted from the projection lens when the illumination source is run at peak output and an entirely white image is displayed (that is, all DLP micromirrors are in the “on” position). All else equal, higher brightness optical modules can project images that are easier to see, particularly in brighter ambient lighting conditions, because they can create a greater difference in brightness between the projected content and the background projection surface.
Higher brightness generally comes with system tradeoffs such as larger module size and higher power consumption. These tradeoffs are mitigated by the high optical efficiency of DLP technology, which enables high brightness from small, low-power optical modules. To learn more about the brightness specification and its impact on system tradeoffs, please read the Brightness Requirements and Tradeoffs application note.
Brightness of an optical module can vary as its white point (i.e. the relative mix of red, green, and blue light that creates white light) is adjusted. For the most accurate measure of performance, brightness should be specified with a target white point. For example, D65 (6500 K) is an industry standard.
