led tv block diagram with explanation
This article is about Light-emitting diode (LED) based video displays. For LED-backlighted displays, see LED-backlit LCD display.Not to be confused with Vacuum fluorescent display.For segment displays, see Seven-segment display, Nine-segment display, Fourteen-segment display, and Sixteen-segment display.For matrixed text displays, see Dot-matrix display.
The 1,500-foot (460 m) long LED display on the Fremont Street Experience is currently the largest in the world.
An LED display is a flat panel display, which uses an array of light-emitting diodes as pixels for a video display. Their brightness allows them to be used outdoors in store signs and billboards, and in recent years they have also become commonly used in destination signs on public transport vehicles. LED displays are capable of providing general illumination in addition to visual display, as when used for stage lighting or other decorative (as opposed to informational) purposes.
An LED-backlit LCD is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs.[1] LED-backlit LCD TVs use the same TFT LCD (thin film transistor liquid crystal display) technologies as CCFL-backlit LCD TVs. Picture quality is primarily based on TFT LCD technology, independent of backlight type. While not an LED display, a television using this display is called an “LED TV” by some manufacturers and suppliers.[1] In the UK, the Advertising Standards Authority has made it clear in correspondence that it does not object to the use of the term “LED TV”, but requires it to be explained in advertising.[2]
Three types of LED may be used:
Edge-lit LEDs - in which the LEDs are formed around the rim of the screen, using a special diffusion panel to spread the light evenly behind the screen (the most common use)LED backlighting (Full array)- behind the screen, whose brightness is not controlled individually
Dynamic “local dimming” backlight - LEDs controlled individually (or in clusters) to control the level of light/color intensity in a given part of the screen.The iPhone 5 has an LED-backlit TFT IPS LCD, while the Sony Xperia S is an example of an LED-backlit TFT TN LCD (also referred as TFT LCD).
