The adoption of LED backlights in liquid crystal panels has also been rapidly developed in notebook computers and liquid crystal display panels in addition to television panels. In the following, we will summarize the latest LED trends introduced by analysts on the "Display Search LED Forum 2010" held on May 11 in the LED backlights in the LCD panel for computers.
Among the applications of large-screen LCD panels, the earliest popularization of LED backlight panels is notebook computers. With the improvement of LED luminous efficiency and low price, in addition to the high value-added mobile personal computer originally equipped with LED backlight, almost all models equipped with small notebooks (the screen size is less than 10.2 inches) listed after 2008 are equipped. LED backlighting. Moreover, from the first half of 2009, the main products of notebook computers with screen sizes of 15.6 inches and 14 inches have been rapidly promoted. It is estimated that the supply of notebook computers (including small notebook computers) in 2010 will be 214 million units, which is estimated to be equivalent to 88% of the 188 million units will use LED backlight panels.
On the other hand, in 2009, liquid crystal displays were preferred to use panels that reduce the number of CCFLs (cold cathode tubes) compared to LEDs. Therefore, 2010 will be a year in which LED backlight panels are fully popular. In 2010, the supply of LCD monitors was forecast to be 117 million units, equivalent to 15% of the 26 million units expected to use LED backlight panels. The LED backlight in the notebook panel is roughly divided into a Wedge Type and a Flat Type according to the shape of the Light Guide Plate (LGP: Light Guide Plate). The wedge uses a wedge-shaped light guide as it literally means. Since the composition, shape and panel construction of the components are close to CCFL backlight panels, the currently cheaper LED backlights are the main products. The premium (increase) relative to the CCFL backlight panel is $2 to $3. The flat plate shape is a product using a thin plate-shaped light guide plate. Since the LED is also a thin product, the thickness of the entire panel can be suppressed. The premium to the CCFL backlight panel is $5 to $10. With the improvement of the yield and the low price in the future, it is expected that the light guide plate will gradually transition to the flat shape.
The LED backlight in the display panel is used from low-cost models such as 18.5 inches. The LED backlight premium of the display panel is currently $2 to $6, but since the inverter circuit used in the CCFL backlight mode is not required, it can eventually be offset. Moreover, due to the expansion of the use of LEDs in small-screen televisions using display panels, LED backlighting has been adopted since the model of small-screen images. In addition, in some business applications such as images, since the color expression and life characteristics are different from those of the CCFL panel, TV manufacturers who have suspended the LED backlight panel are also widely available.
Although the supply of LED backlights has expanded rapidly, it has been short-lived and has not accumulated design techniques and experience in the use of components. In the case of LED luminous efficiency and basic performance improvement, panel makers and TV manufacturers have more room for additional value added. (
