In November 2013, the total revenue of listed LED manufacturers in Taiwan was slightly down by 1.49 to 10.84 billion yuan. Among them, Taiwan's LED chip makers' revenues reached NT$3.95 billion (-4.9MoM); while Taiwan's LED package manufacturers' revenues also reached NT$6.73 billion, and MoM grew slightly by 1.76.
LED backlight part, benefiting 4K2K high-resolution TV backlight and OD15 direct-type TV backlight demand increase, in the same TV panel size, 4K2K TV can increase 1.2~1.5 times of LED backlight usage, OD15 slimming version of direct-lit TV The number of backlight LEDs is 25~30 more than that of the general OD25~OD30 direct-type TV. In addition, the channel inventory gradually returns to the healthy water level and the Chinese New Year is ahead of the end of January, and LED manufacturers have already felt the stocking order in advance. With the tide of goods, and reaction in November revenue, such as Jingdian, Yiguang, Ronda and Rongchuang and other manufacturers. However, LEDinside also observed another phenomenon, because the penetration rate of direct-lit LED-backlit TV will increase to 60 next year, of which OD15~20 slimming version of direct-lit TV accounts for about 20, and the remaining 80 are mainly OD25~OD30 models. Take the 32-inch TV in 2014 as an example. The OD15 backlight uses 21~24 LEDs, and the OD25~30 backlights only 15~18. In 2014, the total number of TV backlight LEDs used was about 11.83 billion, and the annual decline was 19.2.
Lighting applications in the LED terminal lighting market demand for hot, especially LED bulbs, lamps, MR16 continue to drive the development of the LED industry, including Seoul Semiconductor (SeoulViosys), Taiwan Jingyuan Optoelectronics and China Sanan Optoelectronics, Huacan Optoelectronics and other major LEDs In addition to the expansion plans, chip manufacturers have successively upgraded MOCVD machines to 4å‹ production. In 2014, with the strong market demand for bulbs shipments increasing by 70, the demand for medium-power LED packages is bound to expand. EMC lead frame manufacturers are also actively expanding production, and Philips Lumileds plans to introduce mid-power flip chip packaging products next year. OEM OEMs in Europe and the United States are the main source of lighting revenue for Taiwanese LED manufacturers, but next year they will face strong threats from Chinese LED manufacturers.
Overall, LED manufacturers actively develop high value-added products in order to resist the rapid decline in price of backlight LED unit price ASP, such as NTSC with more than 90 LEDs with higher color saturation; develop higher energy efficiency (lm/W) and higher cost performance ( The LED product of lm/$) is the best direction for Taiwan LED manufacturers to fight for European and American lighting OEM orders.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
