LCD Basics Transflective LCD Transflective LCDs are a mixture of the reflective and transmissive types, with the rear polarizer having partial reflectivity. They are combined with a backlight for use in all types of lighting conditions. The backlight can be left off where there is sufficient outside lighting, conserving power.

LCD TV LCD TV is a television display technology based on a liquid crystal display. LCD TVs consume much less power than plasma displays because they work on the principle of blocking light rather than emitting it. An LCD display uses either a passive matrix or an active matrix display grid. The active matrix LCD is also known as a thin film transistor (TFT) display.
