Talk:Transreflective liquid crystal display

From Wikipedia, the free encyclopedia

This page is not completely accurate. The description of a transreflective display is close, but not detailed enough to distinguish between the various ways of achieving transreflectivity. The "trade name" examples are definitely wrong. The two examples given are transmissive LCDs that have had top-surface treatments to reduce the surface reflectivity. A transmissive LCD with this treatment can be seen outdoors if the backlight is bright enough and the surface reflectivity is low enough (an example of an actual product is the Dell ATG laptop). But as the sun gets brighter (above 30K lux, heading for 100K lux), the screen becomes less readable because the effective contrast ratio drops. With a transreflective display, as the sun becomes brighter, the screen becomes more readable because more light is reflected from the reflective portion of the pixels (or from the retroreflector film, if that's the mode of construction that's employed).

I could rewrite this page, but I just don't have the time.
