LG Display seeks to win under direct LED backlight technology

LED is coming, the enterprises especially the fierce competition between manufacturers and technology has quietly begun, is not easy to identify the quality first, or in the visible appearance of ultra-thin win? This is a worth looking forward to the race.

LED technology is about to open a new era of flat-panel display

The pursuit of high quality film to promote the continuous progress of flat-panel TVs, but also guide the new round of consumer trends. If the use of CCFL (cold cathode fluorescent lamp) for the backlight LCD TV is "artificial light" image quality, then the LED (light-emitting diode) as the light source, it can be said to provide "natural light" quality. Even the industry can not wait to stand, LED era is coming.

From the research China Electronics Standardization Institute, China Electronic Chamber of Commerce jointly issued the "LED TV key performance indicators diagnostic test results" data display, LED TV in color gamut coverage rate, power consumption, dynamic contrast and brightness uniformity of several key indicators than the average level of the traditional liquid crystal TV products have greatly improved the color gamut coverage: rate (NTSC) upgrade from the traditional LCD TV 75%-100% to 105%-113%; the power consumption is reduced by 40% on average; dynamic contrast ratio is more than 25000:1. Experts said that by 2010 there will be 30% LCD TV using LED backlight, gradually replacing the industry generally used CCFL.

Direct backlight VS side light, who is better?

Fierce competition among enterprises, especially the panel manufacturers have begun quietly. Although the use of LED technology, but there are still different principles. Recently, the industry are concerned about the launch of the LG Display straight down ultra-thin LED backlight module. It is understood that the thickness of this product is controlled at 2.4cm, thinner than the current thinnest LED tv!

LED TV is a LCD TV with LED backlight. Design methods, display manufacturers generally use straight down and side light these two ways. The side light type LED module is installed at the border of each panel, so that the light source can be seen from the side, and the light generated by the light is diffused between the reflection plate and the light guide plate after the panel, and then the LED is transmitted to the screen. The advantage of this approach is to minimize the thickness, but because of the inability to transmit light evenly, the screen brightness will be reduced to the form of "X". Compared with the straight down backlight, metering technology needs more auxiliary technology to improve the reflection and light guide.

The direct way is to evenly distribute the LED on the back of the panel, and the light of the light source can be evenly distributed on the whole picture. At the same time, it uses Local Dimming (area control) technology, a substantial increase in the ratio of light and shade. Local Dimming the LED backlight unit is divided into a chessboard, as a separate control of each area, when the display black, turn off the corresponding LED area of light, can show a very perfect black. Therefore, experts generally believe that the direct backlight can be more accurate image, and show excellent color and light and shade contrast effect. However, the LED emission of light requires a certain space, direct type backlight technology to reduce the thickness, need to install more LED more closely, the wide diffusion space minimization or the power supply part of the substrate such as a tuner, a separate part. Because of this, the thickness of the thickness of the LG Display control to the 2.4cm straight down LED backlight module, so that the industry is very amazing, it can be described as a perfect solution to the dilemma between the quality and slim appearance.

Strive to look forward to the quality of the game

Quality is the core of the tablet. Compared to the traditional LCD TV, LED TV in the screen performance, environmental protection and energy saving, ultra-thin appearance, entertainment features, color and other aspects have been fully upgraded. And straight down LED TV, it is these features dripping play. The industry believes that the LG Display ultra-thin direct type LED module come out, will end side light and straight down this two design styles in ultra-thin appearance with more excellent quality demands of differences, because it achieved perfect unity. Driven by the LG Display, straight down backlight technology will therefore be more likely to become potential.

LCD era, LG Display in order to highlight the dynamic picture quality requirements, creating a legendary hard screen world. It now appears that in the face of the upcoming LED era, LG Display is also fully prepared. At present, the LG 240Hz LED panel and only the thick 5.9mm side light LED panel module has also come out in the near future, fully demonstrated the strength of the panel and the strength of the Display. The future of the LED TV market, who will win more words, will be a game worth looking forward to.
