Apple will release iPad 3 is expected to drive demand for optical components

At present, due to the failure of battery technology to effectively break through, people’s energy-saving requirements for electronic devices have become increasingly strong. For general mobile devices, panel power consumption accounts for up to 30%, reducing panel power consumption is imminent. The light sensor can precisely accomplish this mission, so that the electronic device can intelligently adjust the brightness of the panel to achieve the purpose of reducing power consumption. At the same time, the addition of the light sensor can also help the electronic device realize more special human-computer interaction functions.

Our data shows that since 2009, driven by the iPhone and Android phones, smartphones have entered explosive growth. Shipments increased from 36.51 million units in the first quarter of 2009 to 149.04 million in the fourth quarter of 2011. Taiwan, the quarterly shipments increased by 3 times.

Smartphone shipments also increased from 14% in 2009 to 31% in 2011. We believe that smart phones will continue to grow rapidly in the future, which will inevitably drive the growth of the optical sensor market.

For example, Apple's upcoming iPad 3 is expected to use the Retina (retina) display. Without changing the TFT (Thin Film Transistor) technology, dual LED tubes are needed to maintain the same backlight brightness as the current iPad 2. Design, so that energy consumption will increase significantly. Therefore, high-resolution screens are more urgent to reduce panel power consumption, and the demand for light-sensitive components is also stronger.

In addition, Ultrabook (light and thin notebooks) has limited space (especially thickness) to place batteries under the requirement of thin and light, which limits the battery power, which requires it to reduce the power consumption of the device through other means. The introduction of optical sensors will be a more effective method, and many Ultrabook manufacturers are actively importing optical sensors.

At present, the world's top three suppliers of ambient light sources are Austrian Microelectronics, Avago, and Intersil. In addition, Taiwanese manufacturers have also accelerated their penetration of the light-sensing market. Various manufacturers are actively preparing for expansion this year.

We believe that the low-end and mid-range components in the future will enter a state of complete competition under the strong layout of Taiwanese manufacturers. However, due to the strong market demand for high-end light-sensing devices, and the difficulty of quick supply, the market outlook is promising.

Many companies in China have begun to set foot in this field. Therefore, the future of the light-sensitive industry deserves attention.
