Fight Side Of The Led Technology Is Leading
LCD TV When the surprised many people; Six months later
, when the LED TV after the rapid warming in the global market, has amazed colleagues Samsung foresight Marketing Way. The rapid proliferation of LED LCD TV, Samsung contributed, as it directly provides a significant reduction in the cost of LED TV solution??? White side-in LED TV.
As CCFL (cold cathode fluorescent tube) backlight perfect upgrade LED backlight Since the introduction of technology has been under Sony, Sharp, Samsung and other TV giants of esteem, these enterprises are also investing in R & D cost-saving technologies. When Sony, Sharp is committed to the perfect quality of the three-color RGB-LED lower cost options, the Samsung is the sword go the wrong front, the first to introduce white light source, at the same time into the structure with a side light to replace direct type, although not perfect, but boost the LED LCD TV's popularity.
RGB-LED high-cost short-term difficulty falling
Any good technology, in order to widely used to lower the cost. During this time, color TV market is one of the most popular vocabulary LED, this four or five years ago hit the technology because of the sharp decline in manufacturing costs, the protagonist of this year's market.
Turned the history of LED technology, we can easily find, LED LCD TV today sells and TV manufacturers to "give up" are closely related.
LED backlight technology are three kinds: direct type tri-color RGB-LED light source, white LED light source and direct type-type white LED light source side. Among these, the earliest is three-color RGB-LED technology.
And traditional CCFL backlight Technology compared with, RGB-LED TV The major advantages of expression embodied in the color and contrast two aspects: As a result of RGB primary colors independent light emitting device, the RGB-LED TV's color gamut to achieve the NTSC great for more than 120%, some well-tuned models can even reach 150% of color gamut, fully met or exceeded Plasma TV Standards.
Additionally, RGB-LED backlight TV can also support regional adaptation, brightness adjustment is very easy to implement, so the contrast is concerned, are often able to reach 10 million dynamic contrast ratio, this TV's image quality for the upgrade has a very critical role.
RGB-LED technology have obvious advantages for Sony, Sharp, Samsung and other global TV giant peremptorily children invested heavily in research and development. Those years, Sony, Samsung, Sharp is launching a number of RGB-LED-based technology products, but prices are abnormally high. From there to now, although the RGB-LED technology after years of development, but there is no substantial cost reduction, and slowly, these enterprises have reduced the RGB-LED technology R & D, RGB-LED in the voice market, the more to the smaller.
Reporter learned that previously the main push RGB-LED LCD TV a few big companies are doing now white LED TV, such as early release of the 8000 Series Samsung LCD TV with LED white side-in approach, Sharp is launched with white LED light source LE700 Series, Sony's KLV-40ZX1 latest TV also used the white LED backlight. During this period, although Sharp has introduced a small amount of RGB-LED product, but available as Sharp high-end products, their prices are too expensive, there is no market penetration possible.
Next year is expected to substantially reduce the cost of
"Technically speaking, RGB-LED perfect, but the cost issue has been difficult to overcome, in contrast to the costs, we will focus on the past few years research and development on white LED light source." Samsung Electronic Managing digital imaging research and development center into Hong Pyo told the "China Electronics News" reporter.
