CCFL era has passed LED monitor will become mainstream this year

The "LED display" refers to the LED backlit display. Compared with the previous light source, LED has many advantages, such as lightweight, energy saving, durability and so on, so it has been gradually applied in many fields, such as display equipment, instrument indicator lamp, lighting source and so on. In the field of liquid crystal display, LED is mainly used in backlight, CCFL backlight better than before in life, luminous efficiency, so it will become the successor.

What are we often say "LED monitors"

The full name of LED is Light Diode Emitting, translated into Chinese that is a light-emitting diode, the previous CCFL Chinese name for the cold cathode fluorescent lamp. Apart from the difference in performance and life, CCFL light source is another difficult problem to solve is the use of mercury, and LED light source in this area can be more environmentally friendly.

Speaking of LED, to distinguish the following things: LED display, LED backlight, OLED.

The LED monitor is not strictly a display that we use when we use a computer, but it is generally used for large screen display devices. For example, the opening ceremony of the Beijing Olympic Games is the use of LED display. Large billboards, stadiums and other places will also be used to monitor the LED. The biggest difference between us and the computer used in the display is that the LED display is directly composed of LED light-emitting matrix.

We often say that the "LED display" should be referred to as the LED backlight display, is the use of LED as a backlight source display. This includes white light LED (W-LED) and three color LED (RGB-LED), which has a significant effect on the display of three color LED, while the lower cost of white LED for the display effect is not significantly improved.

OLED is another display technology, do not use the backlight, but a kind of technology to achieve the display effect through the organic material layer on the glass substrate.

Manufacturers to invest in LED backlight products gradually strengthened

Since LED has many advantages over the original technology, its value as a new generation of backlight has long been concerned about LCD manufacturers. However, the cost of the new technology is hindered, until in recent years, LED as a backlight LCD products began to gradually penetrate the market.

In early 2010, the domestic LCD market, the number of products using LED backlight only dozens. At this stage, AOC, LG, BenQ and other brands to enter this emerging market, a number of other brands listed products is lower, but most of the changes in the market has been prepared, this point can be seen from the development of.

Beginning in the second quarter, Samsung products have entered the LED market. Rely on its brand advantage in the entire LCD market, Samsung's LED products in the market share of the rapid rise in the market, gradually narrowing the gap between the first few brands before entering the market. In addition to Samsung, the majority of domestic LCD brand in this period also began to follow up the market quickly.

The third quarter, Samsung's share of attention rose to the top of the market, the pattern of the LED market began to shape. This stage, the domestic market, the number of LED backlit LCD display products have been increased to hundreds.

The fourth quarter, the number and proportion of LED products continue to maintain a high rate of rise, the traditional CCFL products both in terms of the number of shares in the share of attention has been significantly reduced.

LED backlight products share will exceed 50% during the year

With the advent of many LCD brand LED products, LED backlight LCD monitors in terms of market share and focus on the proportion of two aspects have begun to rapidly improve. According to ZDC survey shows that in January 2011 China's LCD display market share of LED products has risen to 46.8%, compared with the same period in 2010 increased by 37.5 percentage points.

In 2010, Chinese LCD market, LED products occupy attention share is almost linear growth, more and more people begin to understand this new backlight technology, and began to look from the traditional CCFL backlight products to LED backlight products. In accordance with this trend is expected in the second quarter of this year, LED backlight LCD display share of attention will catch up and exceed CCFL backlight products.

Due to the user's focus and the focus of the manufacturers are backward LED backlight products, so its market share will continue to grow in the future. It is expected that this year, LED backlit LCD monitor in terms of market share or share of attention, will be more than CCFL backlight products, becoming the mainstream of the market.

Technology upgrades, CCFL will become the past

(Figure) led to a big change in small diodes

The most basic LED is just a light emitting diode. With the continuous development of the past few years, the technology of using LED as the light source has gradually matured, and the production cost is also declining. Whether it is auto meter, or indoor lighting, or we used liquid crystal display, even in the opening ceremony of the Olympic Games, the game scene, you can see the LED light source of the figure, the diode has become a key trigger for this great change.

In the display of this technology products, LED as a new technology is more prominent advantages. Long life, low power consumption, small size, which are consistent with the current IT production
