Spatial light modulators (SLMs)
Many overhead projectors are used with a flat panel LCD which, when used this way is referred to as a spatial light modulator or SLM. Data projectors are often based on some form of SLM in a projection path. A LCD is a transmissive SLM, whereas other technologies such as Texas Instrument's DLP are reflective SLMs. Not all projectors (e.g. some use devices that produce their own light) rather than function as transparencies. An example of non-SLM system are OLEDs. An overhead projector is a display system that is used to display images to an audience. ... Reflective twisted nematic liquid crystal display. ...
