LED TV backlight penetration rate five major trends in 2014

According to the LEDinside Silver Member Report of the Green Energy Division of TrendForce, a global market research organization, LED home lighting and backlight market trends indicate that the output value of LED packaging in 2013 reached 13 billion US dollars, of which LED backlight applications accounted for 20%. Although almost all TVs replace CCFL backlights with LED backlights, the penetration rate of TV backlights has reached a peak. Under the crisis of market saturation, the TV backlight market still has the following trends worthy of attention: Trend 1: Low cost Direct-lit backlight technology is still the mainstream in the market According to LEDinside survey, the proportion of direct-lit backlight TV in 2014 will reach 60 market share. Direct-type TV backlight technology provides a cost-effective solution due to the continued cost reduction of panel makers or TV brand manufacturers. Since the direct-lit backlight technology can reduce the number of LEDs used, the backlight cost can be further reduced, but the disadvantage is that the direct-lit backlight TV has a thicker influence on the appearance. Currently, the OD (OpticalDistance) 25~35mm model is still a direct-type TV. Shipment main force. As the direct-lit backlight uses a larger wattage of LEDs, the cost of future direct-lit backlight LEDs is expected to be further reduced. Trend 2: Side-light technology will still exist in thin-type TVs in the future. Although the cost of direct-lit backlights is relatively low, there is still not much progress in the thinning of TV appearance. At present, LED manufacturers generally face insufficient optical lens production capacity with a larger angle of light. In order to reduce the cost, they will increase the cost and lose the cost advantage of direct-lit backlight. LEDinside observed that if the cost of OD15 cannot be reduced, and the cost of some TVs is even higher than that of the sidelight type, LED manufacturers may increase the proportion of sidelight strips shipped in 2015. In 2014, the average luminous efficiency of TV-side light-backlit LEDs was about 110 lm/W, which was more advantageous for high-end thin TVs with side-light cost. Trend 3: 4K TV rises into a backlight LED new growth momentum LEDinside estimates, 2014 4K2K TV penetration rate is expected to reach 5-6.4K2K TV prices are still high, taking 55-inch panel quotes as an example, 4K2K panel offer is FullHD panel 1.6 to 1.7 times, if the spread can be reduced to less than 1.3 times, 4K2K TV sales are expected to grow. Trend 4: The rise of China's packaging power Whether it is the influence or market share of TV brands, Chinese brands have begun to occupy a place. According to the estimated global TV shipments in 2013, China's six major brands have already squeezed into the top 15, including TCL and Hisense won the fifth and sixth place respectively, with 137 million units and 115 million units surpassing Japanese manufacturer Panasonic. In addition, Skyworth and Konka’s shipments were also ranked 8th. With the 10th place. With the rise of China's panel or TV brand manufacturers, the supply chain has begun to change as China's packaging manufacturers become more mature and price competitive. Ruifeng, Zhaochi, Dongshan Precision, etc. have entered the TV backlight supply chain. Trend 5: Xiaomi launches the smart TV market layout, driving Chinese brand manufacturers to follow up with Xiaomi to launch the second generation of new TVs. Xiaomi's new TV is expected to be mass-produced in the second quarter. The TV screen size is enlarged from the current 47 inches to 49 and 55. Inch, the main high-resolution 1,920x1,080 narrow-framed 3D LCD panel, priced at 2,999 yuan, in just a few months, Xiaomi has been paving the way for the second generation of TV, the speed is quite fast, Xiaomi still We will adopt a high-quality, low-price strategy to fully seize the mainland smart TV market. The LED specification uses a 7020 LED package, which uses a total of 128 LEDs, and two light bars are used in the US TV. This trend is also expected to drive Chinese brand manufacturers to follow up.

High Frequency Vibrating Screen introduction

High Frequency Vibrating Screen, simple structure,light weight to move and freely adjust height, The vibration frequency is high up to 3000 times per minute. High screening precision and efficiency, it applies to any powder,granule . In addition to electrical parts, the other parts are made of SUS304 or SUS316L.

Working principle

The high frequency Vibrating Sifter is a different working principle compared with ordinary screening device. Because of high frequency , it is able to destroy the tension on pulp surface, make small grain material vibrate at high speed on surface, able to accelerate to the separation of heavy organic minerals, increase the probability of material (smaller than separation degree) contact with screen hole. Thus this unique characteristic has created better separating condition that make the material (smaller than separation degree) pass the screen hole easily, especially the large proportion of grain and slurry, too.
