com, of which led modules accounts for 39%, integrated circuits accounts for 1%, and switches accounts for 1%.. [2][3]While not an LED display, a television using such a combination of an LED backlight with an LCD panel is called an LED TV by some manufacturers and suppliers.. The evolution of energy standards and the increasing public expectations regarding power consumption have made it necessary for backlight systems to manage their power.

There are several methods of backlighting an LCD panel using LEDs, including the use of either white or RGB (Red, Green, and Blue) LED arrays behind the panel and edge-LED lighting (which uses white LEDs around the inside frame of the TV and a light-diffusion panel to spread the light evenly behind the LCD panel).. This was possible because red, green and blue LEDs have sharp spectral peaks which (combined with the LCD panel filters) result in significantly less bleed-through to adjacent color channels.

There are a few techniques that can be employed to make the LED backlight brighter, but if your goal is to compete with (or against) the direct sun light, there are better methods than to increase the brightness of the backlight.. 5 inches (13 mm) thin in edge-lit panels)Significantly lighter and cooler, as much as half the total chassis and system weight of a comparable CCFLTypically 20–30% lower power consumption and longer lifespanMore reliable[9]LED Arrangement[edit]Direct LED full array of a smaller LCDLED backlights replace CCFL (fluorescent) lamps with several dozen to several hundred white or blue LEDs.. [1] LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit displays, but offer reduced energy consumption, better contrast and brightness, greater color range (using more expensive RGB LEDs, blue LEDs with RG phosphors, or a quantum dot enhancement film (QDEF)), more rapid response to changes in scene (with dynamic backlight dimming), and photorefractive effects.. RGB LED technology continues to be used on Sony BRAVIA LCD models LED backlighting using white LEDs produces a broader spectrum source feeding the individual LCD panel filters (similar to CCFL sources), resulting in a more limited display gamut than RGB LEDs at lower cost.

Unwanted bleed-through channels do not 'whiten' the desired color as much, resulting in a larger gamut.. The commercially called 'LED TV's' are LCDs-based television sets where the LED's are dynamically controlled using the video information[11](dynamic backlight control or dynamic “local dimming” LED backlight, also marketed as HDR, high dynamic range television, invented by Philips researchers Douglas Stanton, Martinus Stroomer and Adrianus de Vaan [12][13][14]).. Two types of LED arrangement may be used:Edge-lit LEDsLEDs form a line around the rim of the screen, with a special diffusion panel (light guide) to spread the light evenly behind the screenDirect LED full arrayLEDs form an array directly behind the screen at equally spaced intervalsIn Full array local dimming (FALD), LEDs are controlled individually to dynamically control the level of light intensity in a given part of the screen.. “We need the brightest LED backlight possible for our new LCD design and we need to make sure that the LCD is sunlight readable.. [10]Technology[edit]LED-backlit LCDs are not self-illuminating (unlike pure-LED systems). Gratis Cara Di Mega Dengan Idm 2015

9,224 led backlight module products are offered for sale by suppliers on Alibaba.. This method of backlighting allows local dimming of specific areas of darkness on the screen, resulting in much higher dynamic-contrast ratios, though at the cost of less detail in small, bright objects on a dark background, such as star fields or shadow details.. A wide variety of led backlight module options are available to you, such as ce, rohs.. ” This is a common request and the Backlight Module Dmg Bright Spot Lcd ReplacementBright Spot JakartaBright Spot DinerBacklight Module Dmg Bright Spot Lcd ScreenBacklight Module Dmg Bright Spot Lcd ScreenAn Apple iPod Touch disassembled to show the array of white-edge LEDs powered on with the deviceA LED-backlit LCD is a flat panel display that uses LEDbacklighting instead of traditional cold cathode fluorescent (CCFL) backlighting.. Variations in LED backlighting offer different benefits The first commercial full-array LED-backlit LCD TV was the SonyQualia 005 (introduced in 2004), which used RGB LED arrays to produce a color gamut about twice that of a conventional CCFL LCD television..
