Real Time LED Display for the ‘Visual Factory’!
Patlite report the introduction of the new VE series LED Display; a Lean Manufacturing Tool for achieving ‘Kaizen’ on the factory floor.
Two models (1” or 4” character height) are available providing 3 lines of display showing goals, targets, progress, balance, and efficiency, as well as overall or piece-by piece times. Patlite state that this is a simple, economical system for reducing down time and eliminating waste by keeping all of your production line in step for maximum output efficiency. 3 programmable DC24V outputs are provided for visual or audible signaling of critical situations. Setup is easily accomplished using a PC or an optional remote control.
surged to RMB 29.46 billion, up 33.8% from 2009. Meanwhile, the CAGR of China’s LED industry stayed at 18.7% from 2006 to 2010.

Although the substrate sector still features low-end products, the sapphire sector has geared up for expansion.
In recent years, the development of China’s substrate sector has been relatively slow compared with epitaxial, chip, and packaging sectors due to its backward technology and the fierce market competition. In 2010, as various sapphire substrate projects were still under construction or in the process of equipment testing, which kept the production capacity from a significant expansion, the substrate sector still featured low-end products with a limited production capacity of sapphire substrate. In 2010, China’s substrate sector had a capacity of 3.525 million square inches, up 34.4% from 2009, with an output value of RMB 140 million, up 50.8% from 2009.
China’s LED industry speeds up
China’s LED industry has seen significant development after the initiation of the National Semiconductor Illuminating Project in 2003.
In 2008, the industry’s growth rate was affected by the sluggish downstream demand, which was a result of the global financial crisis. In 2009, with the state’s various supporting policies, the industry’s growth rate began to pick up. In 2010, driven by the rapid development of the downstream full colour LED display, LED backlight, LED lighting and other applications, the size of China’s LED industry covering substrate, epitaxial, chip and packaging

Supported by National Semiconductor Illuminating Project and State 863 Program, China’s GaAs/InP/ GaP substrate technologies used for red light and green light LED production have achieved great progress. Mass production of the materials has been realized in enterprises including Compound Crystal Technology Co., Ltd, Guorui Electronic Materials Co., Ltd, Shanghai Pujia Optoelectronic Materials Co., Ltd. and the 46th Research Institute
