Under the trend of thin-film LCD TVs, the new LED TV side-light strips of the new panel of the Korean panel factory will be changed from the current mainstream 4 to 2, and the outside world is worried that the number of LEDs used on the panel will be greatly increased. The reduction, the research institute WitsView pointed out that under the cost reduction, it is expected to significantly stimulate the penetration rate of global LED TV next year.
In order to maintain the uniformity of brightness, the LED usage in the LED TV backlight module has always been the main reason for its high cost. WitsView pointed out that thanks to the continuous improvement of the light guide technology and LED luminous efficiency, the reduction of the number of LEDs is a Constant trend.
In 2010, the mainstream LED TV adopts the edge-light backlight, and the LED backlight module is a 4-light strip double-sided light-emitting design. Under the Korean manufacturers actively pursuing the thinning of the LCD TV, the spring of the first season of Ming (2011) The new LED model TV, the edge-lit backlight will adopt a new generation of design.
It is understood that in order to respond to the new model of the Korean factory in the first quarter of next year, the 42-inch new model of the LED backlight module factory in Taiwan will be changed to the left and right sides of each light strip. The number will be less than the design of four double-sided lights.
WitsView analyst Qiu Yubin said that the light source accounts for more than 50% of the LED TV backlight module. This breakthrough design will reduce the cost of the backlight module. For large-size panels, it will directly save the panel factory cost of about 20-30 dollars. .
Qiu Yubin also analyzed that in fact, the four double-sided light-emitting design is also an alternative to the original six light strips and four-side light-emitting structure. At that time, the panel manufacturers directly saved about one-third of the light source cost.
"The LED TV penetration rate has to grow upwards. The most important thing is to reduce the cost first, in order to stimulate the sales of LED TVs." Qiu Yubin explained that the current Korean manufacturers are the fastest, and the fast Taiwanese factories such as AUO Xinqimei, etc. will follow up.
LEDinside pointed out that the edge-lit LED backlights are arranged on the peripheral edge of the LCD screen, and then matched with the light guide plate, so that when the LED backlight module emits light, the light emitted from the edge of the screen is transmitted to the central area of ​​the screen through the light guide plate. Let the LCD screen display the picture.
LEDinside analysis, side-lit LED backlights can use fewer LED dies, saving a certain cost; side-light can also create a thin and light body, so that LED TV LCD panel does not need to be equipped with LED modules behind, but Place it on the side to reduce the overall thickness of the screen.
