LED is the fourth revolution of human illumination after fire, incandescent and fluorescent lamps. The essential difference between the previous three times is that LEDs rely on current to directly radiate photons through solids. The luminous efficiency is ten times that of incandescent lamps. Times. At the same time, the service life is up to 10,000 hours, anti-vibration, good safety, not easy to break, very environmentally friendly.
With the continuous advancement of technology, the luminous efficiency has been further improved, and the unit cost has continued to decline, and the application fields of LEDs have been continuously expanded. LED applications from early instrumentation indicators, traffic lights, landscape lighting and mobile phone backlights, to the current automotive lighting, notebook backlighting, will be applied to large-size LCD monitors, LCD TVs, and even general lighting in the future, the market prospects are very broad.
Taiwan is a major town in the global LED industry. Since the first LED packaging production line began in Taiwan in 1972, the LED industry has achieved rapid development in Taiwan, currently accounting for 25% of the global LED industry output value, second only to Japan. However, in the past year, Taiwan's LED industry has fallen into a trough, and the performance of major companies' stock prices have fallen sharply below the broader market. The monthly revenue growth rate has dropped month by month and even began to show negative growth.
The main reason for the decline of Taiwan's LED industry is the slowdown in downstream demand and the substantial expansion of production capacity. The backlight of mobile phones is now the main application field of Taiwan's LED industry. Since 2008, the growth rate of mobile phone demand has been lower than expected, and the price of small-sized LED panels used in mobile phone backlights has gradually declined. At the same time, LCD panel makers such as AUO and Chi Mei have invested heavily in capacity expansion. As the upstream is the main area of ​​capacity expansion, it is also the most affected.
Like other emerging industries, LEDs must also undergo a process of continued capacity expansion, increased industry competition and falling product prices. LED is an industry with rapid technological advancement and significant scale utility. We believe that only large and innovators can survive. Advances in technology require huge investment in research, and large scales help achieve the lowest production costs. The success of the LCD panel industry AUO and the failure of BOE is an immediate example.
At present, China's LED industry is also undergoing large-scale capacity expansion. It is expected that the average growth rate of high-brightness InGaN LED production capacity will be around 40% in the next few years. The monthly production capacity will increase from 960kk in 2007 to 2767kk in 2010, and also face Taiwan LED. The threat of the industry shifting to the mainland industry. This is an opportunity and a challenge for China's LED manufacturers, and we look forward to the take-off of China's LED.
