An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting.TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.

While not an LED display, a television using such a combination of an LED backlight with an LCD panel is advertised as an LED TV by some manufacturers and suppliers.

The local dimming method of backlighting allows to dynamically control the level of light intensity 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 2016 study by the University of California (Berkeley) suggests that the subjectively perceived visual enhancement with common contrast source material levels off at about 60 LCD local dimming zones.

LED-backlit LCDs are not self-illuminating (unlike pure-LED systems). 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). Variations in LED backlighting offer different benefits. The first commercial full-array LED-backlit LCD TV was the Sony Qualia 005 (introduced in 2004), which used RGB LED arrays to produce a color gamut about twice that of a conventional CCFL LCD television. 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. Unwanted bleed-through channels do not "whiten" the desired color as much, resulting in a larger gamut. 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.

The evolution of energy standards and the increasing public expectations regarding power consumption made it necessary for backlight systems to manage their power. As for other consumer electronics products (e.g., fridges or light bulbs), energy consumption categories are enforced for television sets.

Using PWM (pulse-width modulation), a technology where the intensity of the LEDs are kept constant but the brightness adjustment is achieved by varying a time interval of flashing these constant light intensity light sources,

A first dynamic "local dimming" LED backlight was public demonstrated by BrightSide Technologies in 2003,Sony in September 2008 on the 40-inch (1,000 mm) BRAVIA KLV-40ZX1M (known as the ZX1 in Europe). Edge-LED lighting for LCDs allows thinner housing; the Sony BRAVIA KLV-40ZX1M is 1 cm thick, and others are also extremely thin.

LED-backlit LCDs have longer life and better energy efficiency than plasma and CCFL LCD TVs.mercury, an environmental pollutant, in their manufacture. However, other elements (such as gallium and arsenic) are used in the manufacture of the LED emitters; there is debate over whether they are a better long-term solution to the problem of screen disposal.

Because LEDs can be switched on and off more quickly than CCFLs and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks (LEDs off) and high brightness (LEDs on). However, measurements made from pure-black and pure-white outputs are complicated by edge-LED lighting not allowing these outputs to be reproduced simultaneously on screen.

Quantum dots are photoluminescent; they are useful in displays because they emit light in specific, narrow normal distributions of wavelengths. To generate white light best suited as an LCD backlight, parts of the light of a blue-emitting LED are transformed by quantum dots into small-bandwidth green and red light such that the combined white light allows a nearly ideal color gamut to be generated by the RGB color filters of the LCD panel. In addition, efficiency is improved, as intermediate colors are no longer present and do not have to be filtered out by the color filters of the LCD screen. This can result in a display that more accurately renders colors in the visible spectrum. Companies developing quantum dot solutions for displays include Nanosys, 3M as a licensee of Nanosys, QD Vision of Lexington, Massachusetts, US and Avantama of Switzerland.Consumer Electronics Show 2015.quantum dot displays at CES 2017 and later formed the "QLED Alliance" with Hisense and TCL to market the technology.

Mini LED displays are LED-backlit LCDs with mini-LED–based backlighting supporting over a thousand full array local dimming (FALD) zones, providing deeper blacks and a higher contrast ratio.

LED backlights are often dimmed by applying pulse-width modulation to the supply current, switching the backlight off and on more quickly than the eye can perceive. If the dimming-pulse frequency is too low or the user is sensitive to flicker, this may cause discomfort and eyestrain similar to the flicker of CRT displays at lower refresh rates.

A backlight is a form of illumination used in LCD. As LCD do not produce light by itself, unlike CRT. LCD display needs illumination, ambient light or backlight, to produce image. Currently, there are two types of backlight in the market, CCFL and LED.

CCFL：Traditionally, TFT LCD used Cold Cathode Fluorescent Lamp as backlight. It was the major player in market, before LED backlight was introduced. CCFL is a mature technology, and provides stable color light source. However, CCFL backlight is relatively bulky and is not energy efficient. It is phasing out of market now.

LED:LED backlight on the other hand is small, low power consumption, has high brightness and long service time. That is why LED is taking over LCD backlight market share from CCFL.

LED, in full Light Emitting Diode, is a semiconductor diode that emits light when electric voltage is applied to it. We can separate LED backlights into two groups, based on their installation locations.

Edge-lit: LED light bulbs are affixed on the edge of TFT LCD display. A light guide plate (acrylic panel typically made from pure PMMA resin) is used to direct light out the front. Edge-lit LCD backlight can be very thin. But its efficiency is low. The thinner edge-lit backlight is, the lesser efficient it will be.

Bottom-lit: As its name states, LED light bulbs are installed evenly across the back of TFT LCD display. The advantages of bottom-lit backlight is its uniformity and brightness. But bottom-lit backlight is thicker than edge-lit, and heating could be a problem.

LED light bulbs are serially connected. When applying constant current to LED backlight, LED temperature goes up. Since supply current is not changed, voltage applied on LED backlight will drop. And LED backlight will produce even brightness.

Because of LED"s unique volt-ampere property, when supplying constant voltage to serially connected LED backlight, higher temperature leads to higher current. And higher current brings more heat. Such effect will be magnified for serial circuit. High current speeds up LED"s degradation and shortens its life span. Further more, since each LED has slightly different volt-ampere property, individual LED will have different pass-thru current. Thus, LED backlight will have uneven brightness.

Therefore, when using TFT LCD with LED backlight, engineer should apply constant current to LED backlight"s power supply, and use PWM function to control brightness.

The Trump Administration Proposed to Apply a 25% Tariff on 1300 Chinese Products, but Would Have Limited Impact on LED Companies in China and Taiwan, Says TrendForce

The Trump administration on April 4, 2018 published a list of 1300 Chinese exports and proposed to apply a 25% tariff on these products. However, the proposal would have limited impact on LED companies in China and Taiwan, according to LEDinside, a division of TrendForce. This is because the LED products included in the list are mainly intermediate goods, including wafers and backlight products. These products account for only a small proportion of all the LED products that China exports to the US market, while most of these intermediate goods produced by Taiwan LED companies are shipped to China.

“Among all the products in the list, categories including 85414020, 85419000, and 90330020, etc. are related to the LED industry”, says Figo Wang, senior analyst of LEDinside. China is a major producer of LED end-products and end-applications, but the three categories above are intermediate goods in the industry. The target market of these intermediate goods includes mainly manufacturers of LED end-products in China. The intermediate goods are not directly sold to individual consumers. Therefore, they only account for a small proportion of LED exports, and contribute to less than 5% of the revenue of LED industry. “There are only a few makers of LED end-products in the United States, which means even less intermediate goods would be directly exported to the United States”, says Wang.

LEDinside notes that, the HS code of LEDs made by China is 85414010. In this list, the category of 85414020 actually refers to solar cell products according to information provided by Chinese Customs. Therefore, the value of LED exports that may be subject to the tariff is only US$46 million in 2017. Even if the category of 85414010 is also included to the list, the value would be only US$129 million. The total value would be less than US$200 million, which would have only a very limited impact to China’s LED exports, of which the total value exceeds tens of billions US dollars.

On the other hand, a large proportion of China’s LED exports to the U.S. are end-applications, such as lighting products in category 94540090 and 94051000, and display products in category 85312000, etc., but the above three categories are not included in the tariff list this time. In addition, as there are only a few US-based manufacturers of end LED applications, most products of branded lighting companies and sales channels are made in China. If these products are subject to the tariff in the future, the LED end-products sold in the U.S. market may face significant price rise.
