iPhone and iPad set off in hot pursuit of global smart phone. Market research firm Gartner recently released a report that the third quarter of 2010, the global end-users up to 417 million mobile phone sales over the third quarter of 2009 increased by 35%, of which smart phone sales grew 96%.
Analysis of the composition iPad, TFT panel, touch-screen components, PCB boards, NAND flash memory, cell phone lithium battery, a microprocessor as its main components. At present, the capacitive touch screen as the focus of market attention. With the hot smart phone, smart phone industry chain-related breakdown of enterprises are also expected to be funded care.
Touch screen: LEYBOLD Tech [56.43 -4.36%] champion
Capacitive touch screen is put on the surface in a layer of transparent glass, a special metal conductive material. When the fingers touch the metal layer, the contact capacitance will change, so connected to the oscillator frequency change, frequency change can be determined by measuring the touch position to obtain information.
