The LED backlight energy saving advantage is a new concept advocated and pursued by people.
CRT display technology has transformed from black and white to color, from analog to digital, and from spherical to flat in the decades of development. Since 2004, flat panel display has gradually gained industry recognition as a second generation display technology. With the maturity of flat panel display technology, the flat panel display industry represented by LCD and PDP is developing rapidly and is becoming the mainstream of the market. In 2009, for LCD displays that currently occupy the largest market share, LED backlight technology has become a new economic growth point for major display manufacturers by virtue of its thinness, clearness, and ability to greatly enhance the color performance of displays. In 2009, the depressed market injected fresh vitality and opened the era of energy saving and environmental protection. Low power consumption and high quality are gradually becoming a development trend Under the background of “protecting the environment and saving energyâ€, under the premise of “scientific and technological innovation and pursuit of qualityâ€, energy conservation and high quality pursuit have become new types advocated and pursued by people. Concept. With years of development, the various technologies of flat-panel TVs have been relatively mature and the prices are getting lower and lower, but this has not been able to meet the higher demand of some consumers. With the increasing popularity of high-definition flat-panel TVs, consumers are increasingly demanding ultra-thin, high-quality flat-panel displays, and the energy consumption and environmental protection issues of flat-panel displays have become the focus of attention.
According to relevant data, the main focus of consumers' purchase of monitors is on price, appearance, image quality, function, energy saving, environmental protection, etc. Compared with CCFL backlight TV, LED backlight TV itself has a thinner and higher appearance. The advantages of image quality, fast response time, environmental protection and long life have fully catered to the needs of modern society. More than 70% of consumers choose LED backlight display as the most important factor, followed by good quality, energy saving and environmental protection.
The emergence of LED backlights is because of its obvious advantages. Using LED backlights, you can increase color saturation, eliminate smearing, and improve contrast. Moreover, LED is a solid light source, does not contain mercury, and is a green product. The introduction of dynamic backlight technology has greatly improved the quality of liquid crystal display images. The development of LED backlight LED backlight should be a new trend in the development of backlight technology. Since 2008, LED backlight has gradually entered industrialization, and its market share has been expanding. Starting with the original notebook, LED backlight products in displays and LCD TVs are constantly emerging.
In 2008, Apple introduced an ultra-thin notebook with LED backlighting, which led to the expansion of the LED backlight market in the notebook field. Major companies have launched notebook products using LED backlights.
In May 2008, Hisense launched the LCD TV with LED backlight for the first time in China, and Samsung also soon launched its LED backlight series. Several major TV manufacturers in China have started development work on LED backlight TV.
In 2009, the industry generally believes that this year will be the year of adjustment in the field of flat panel display. The new technology led by LED backlight will launch a strong provocation against traditional flat panel display technology. Under the background of shrinking panel industry, Sony and Samsung Large companies such as LG and Dell have built LED backlight products, and LED has become the savior of the panel industry.
According to market research firm iSuppli, global LED sales in 2009 are expected to grow by 2.9% against the trend, although the growth rate is lower than 10.8% in 2008, but the performance is still far superior to other electronic component products with sharp decline in sales. In 2009, the growth of LEDs in the field of backlights was mainly concentrated on LCD TVs, notebook computers, and especially on Netbooks.
The data shows that the era of LED backlight is coming. According to DisplaySearch's research on LED and CCFL backlight and backlight module, LED backlight has become the main development trend of large-size panel. The growth of LED backlight panel shipment will be very fast; according to DisplaySearch forecast, 2011 The shipment of LED-backlit large-size panels will exceed traditional CCFL and EEFL shipments. The LED panel shipment ratio is estimated to reach 56%, and the relative traditional lamp shipment ratio will fall to 44%. At the same time, by 2015, the penetration rate of LED panel shipments will reach 78%.
2006-2015 using traditional CCFL & EEFL lamps and LED backlight large-size LCD panel shipment ratio forecast DisplaySearch pointed out that notebook PC adopts LED backlight is a very obvious trend, in 2009, we estimate that there will be 27.8% large-size LCD panel with LED backlight . With the development of LED backlights in LCD TV applications and brand manufacturers actively adopting LED-backlit LCD TV products, and some new LCD monitors are also catching up with LED backlight trends, DisplaySearch estimates that the LED backlight panel shipment ratio will be further increased in 2010. 44% level. The traditional CCFL and EEFL lamp shipments will be 72% penetration in 2009 and will fall to 56% in 2010.
LED backlight market prospects:
2007-2012 LED shipment forecast by application area (unit: million)
According to the LED shipment forecast report released by Displaysearch, a professional market research organization in the above table, we can see that there will be explosive growth in LEDs used in backlight modules for display products in the next few years. In 2012, it is estimated that LED backlights will be widely used in 1 inch to 70 inch liquid crystal display devices, while 34 billion LEDs will be used for backlighting of liquid crystal display products, which will grow by more than 300% compared with 2008.
According to Yoshio Tamura, senior deputy general manager of DisplaySerach Materials and Cost Research, although LED backlights still have some technical problems and high cost, backlights, panel manufacturers, and complete machine manufacturers are all working hard on LED backlight products. Through these efforts, we have seen that the LED backlight cost structure has been greatly improved, and the cost has also been reduced, accelerating the future development of LED backlight products.
