LCD, or Liquid Crystal Display is a type of thin, flat display screen; these began to appear in some film cameras to display settings in the 1980s. They are now ubiquitous in digital cameras, to display images, menus and settings. On many digital cameras that have them, LCD displays may be the only form of viewfinder provided. Early digital SLRs were only able to review captured images on their rear LCD panels, but used a reflex finder for composing images. As of 2011, "live view" LCD displays are increasingly used on more advanced digital cameras and (as in the case of EVFs) may eventually displace optical viewfinders entirely.
LCDs may be made as full color pixel-oriented arrays, capable of showing full photo images as described above, or as fixed-format modules, only able to display only pre-defined monochrome symbols or numerals. It is the second type which can be found on early low-resolution consumer digicams, or as frame counter and function control displays on film cameras which use electronic controls.
