Strong growth in the LED market, ESS and solid-state lighting is the biggest attraction

With the development and application of manufacturing technology and the progress of new materials, the luminescence efficiency of LED has increased over the past nearly 1000 times, in terms of chroma has basically visible color, can be widely used in electronic signs and signals (ESS, ELectronic Signs and Signals), in particular, backlight, automobile landscape lighting, electronic market, ultra high brightness white LED makes LED applications across to the lighting market become possible.

Annwa technology company (AvagoTechnologies) China area general manager Li Ting said: "in recent years, many LED applications have achieved remarkable growth, especially in ESS, which is one of the key LED high growth market, one of the areas is also the focus of our. ESS applications include variable message signs, traffic signals, full-color display and portable signs, etc.. Annwa high key products in the field is a low Vf AlInGaP through-hole bulb, the product is mainly used to emphasize the low power consumption of solar powered portable logo applications. In addition, the company can also provide SMD type three color (Tricolor) LED products, silicone resin packaging, mainly suitable for outdoor applications.

Annwa launched ESS application oriented full-color latest product is of high brightness Extra Bright II series RGB elliptic in-line type LED lamp, suitable for pedestrian signal, variable message signs, scoreboard and lane lamp design. According to reports, HLMP-Lx63 (4mm, 50 x 100 degree angle standard) and HLMP-Hx63 (5mm, 40 x 100 degree angle standard) LED provides a broad perspective, elliptic light mode and high intensity lighting, can show the contents of any angle in bright sunlight can be clearly identified, in addition, these LED light emitting modes also have fairly stable, and can ensure the consistent effect of mixed color full-color applications, each lamp adopts advanced optical grade epoxide manufacturing, electronic signs and signals for outdoor applications bring good resistance to high temperature and humidity resistance.

From seven to the dot matrix, LED display market boom

The rapid growth of ESS applications also led to the vigorous development of China's LED industry. According to the Ministry of information industry China science and Technology Information Institute and CCID statistics, currently engaged in LED industry, China area of more than 400 companies, including LED manufacturers reached more than and 160, LED chip production from 11 billion 560 million in 2003, rose to 30 billion 930 million in 2006, a compound annual growth rate is as high as 38.8%, the super high brightness light-emitting diode output the growth rate of more than 50%. At present, China in mainland China LED industry has a certain technical and industrial base, the blue LED chip indicators have reached the international level of the mid-range, LED packaging technology and foreign gap, has occupied a large share in the international market. On the other hand, the scale effect of LED industry is gradually emerging, the formation of the Pearl River Delta, Yangtze River Delta, Fujian Delta (Jiangxi and Fujian), Bohai Bay (Beijing and Dalian) in four regions, each region has initially formed a relatively complete industrial chain.

It is understood that the majority of manufacturers in mainland China, the main production of seven LED display, they generally believe that the use of full color SMT and 256 gray level video control technology customized products are currently the best-selling products. The products of high brightness, high resolution, long working life and high stability and other characteristics of the LED manufacturers have attached great importance to. For example, the patch type LED display Hangzhou three photoelectric technology Co. Ltd., pixel spacing of 4, 5, 6, 7.62, 8, 10 and 12mm, the brightness is higher than that of 1CD, also can according to various size LED display customized user requirements of supply.

Xiamen Hualian Electronics Co., Ltd. production of LED display with seven LED display based, but also provide point formation LED display. For example, it is a HJRG5884CB dot matrix LED display, where the red LED power consumption of 22mW, green LED power consumption of 26mW. The rated value is 5V and 10mA, which has high stability and long life.

Zhongshan Dongyang Digital Electronics Co., Ltd. production of through-hole LED display, SMD type text digital display and seven digital display. According to reports, through the LED display screen is composed of solid panels, each LED chip through the hole on the panel light, this panel is more suitable for indoor or semi indoor applications. Some of its seven segment digital display customized products are suitable for air conditioning display panel. In addition, the company can also provide a single color, three color and full color RGB dot LED display, including 5 x 7, 5 x 8, 8 x 8 and 16 x dot matrix panel.

Shenzhen Chang Lian photoelectric Co., Ltd. production monochrome, color and full-color dot matrix LED display. In its three color display, each pixel uses two different colors of the LED chip. The company's full-color LED display using a RGB color scheme. Chang Guang photoelectric monochrome to three color display using an integrated controller board, the configuration can be supported by up to 17 display modes, such as flashing and multi scroll. The company can also integrate other features in its drive board, such as energy-saving mode. The LED display is the wearable and portable product for gift and high-end market. These products are a single line of 7 x 21 point model, each line can display four characters. They are driven by batteries and can work continuously for two days.

On the other hand, its largest model is used for outdoor signage custom full-color module. Each module is a 1 x 1m rectangular display, can be spliced into a larger display. In addition to the point of the formation of digital display, the other LED custom optical display also includes commercial use of edge light (edge-lit) signs
