What is LED LCD TV? What are the advantages?

LED LCD TV prices were snubbed

When the plasma (PDP) and liquid crystal (LCD) fighting smoke gradually dispersed in the tablet market, making their drum beat, a new TV application of LED backlight technology into the line of sight of people, and is the industry as the mainstream in the future of the tablet market. However, this is the major manufacturers to push high-end LCD TV LED, does not seem to imagine the scenery, the price has become too high to be erected in front of the threshold of consumers.

The joint venture brand would use LED to expand the lead

In December last year, in the face of domestic brands launched low-cost storm, the joint venture brand did not follow up, master of the upstream panel resources Samsung, SONY, SHARP have said it would move to high priced LED LCD TV market.

What is LED? For example, last year the Beijing Olympic Games opening ceremony of the opening scroll, and slowly rising in the air of the "Olympic rings" is a masterpiece of LED. It is understood that LED is a light-emitting diode Light Emitting Diode abbreviation, LED applications can be divided into two categories: one is the LED single tube applications, including backlight LED, infrared LED, etc., and the other is the LED display.

Recently, the reporter visited the City appliance stores to understand, at present most of the LCD TV are used in traditional LCD display, the LCD panel itself is not luminous, so need to join the CCFL in the panel (cold cathode fluorescent) to provide backlight brightness required for imaging, and LED LCD screen is a back light the traditional liquid crystal with LED led to the replacement. Compared with the traditional LCD LCD TV, LED LCD TV in the picture of the performance, environmental protection and energy saving, slim appearance, entertainment, etc. color performance has been enhanced, so the international market has been widely regarded as the future of LCD TV product upgrading.

In order to keep the long-term operating high-end brand image be destroyed on one day in December last year, the face of domestic brand, launched a price war, joint venture brands have vigorously promote the development of LED LCD TV, and hopes to further expand the leading edge technology, continue to implement the strategy of winning profit. Subsequently, Hisense, Konka, SKYWORTH and other domestic brands have begun to get involved in this field, launched its own LED tv.

Too high price

However, this is the major manufacturers pushing high-end LCD TV LED, does not seem to imagine the scenery. Recently, the reporter visited the City appliance stores, LED LCD TV is simply one. In addition to Hisense, Konka organic sample, Samsung, SONY, SHARP, Toshiba and other joint venture brand products, due to high prices are required to book.

At this stage of the LCD TV market, or LCD world. Jiangmen Suning's sales staff told reporters, compared with the traditional LCD LCD TV for a year the average price fell to 1/3, LED LCD TV prices high daunting. It is understood that the ordinary 42 inch LCD TV has dropped to 5999 yuan, and the product is rich, high selectivity, and domestic LED LCD TV prices of the same size to 12999 yuan, is 2 times that of the former, and joint venture brands the price gap is larger, such as the SONY 55 inch LED TV price up to 50999 yuan but, with the size of the domestic LCD TV prices have been as low as 9999 yuan, more than 5 times the price. Even the same kind of technology, the price disparity, therefore, the price has become one of the popular "tiger LED LCD tv".

Insiders told reporters that the high cost is the main reason causing the high price of LED LCD TV, the larger the size, the quality is outstanding, need LED (light emitting diode) is more, using the LED backlight technology is more expensive. At the same time, as a new display technology, LED backlight technology is not very mature, such as LED because the lattice is quite dense, the heat problem is difficult to solve, it will affect the so-called long life of the LED diode using time, therefore still need to continuously improve the technology, so manufacturers R & D cost is very large. In addition, there is a cost of transition, the major manufacturers of LCD production line is the LCD module, if the transition is too fast, the existing production line is idle before not to recover the cost, it will cause huge waste. The source added. Many businesses said, in addition to price factors, consumer LED backlight LCD TV lack of awareness, but also one of the reasons affecting the popularity of LED tv.

However, for the TV LED's future development prospects, the industry generally optimistic, that any new products need to have a period of market cultivation process, with LED backlight technology continues to improve, and large-scale commercial production, the next few years, LED LCD TV will be even from flagship products to high-end products, the mainstream product model the popularization, and become the dominant market.

LCD TV to change current molecular arrangement, applying different voltages can be controlled by the amount of light to the liquid crystal display, and image varied, but the LCD itself is not light, therefore need to back light. LCD TV is the traditional CCFL (cold cathode fluorescent lamp) as the backlight source, CCFL light-emitting principle and common fluorescent lamp is very close, but the CCFL service life of only 50 thousand hours, with the time increasing, the light will be dark and yellow. In addition, the biggest defect of CCFL lies in its spectral properties, and the white light emitted by the backlight is the last
