First understand that 4.5G TFT LCDs are used in 10.4in and smaller panels. These are made into 1.8in to 4in LCD screens which are built in mobile phones, MP3/MP4 players, digital cameras, PDAs and video game consoles; as well as 5in to 10.4in LCDs for car navigation devices, portable DVD players, digital photo frames, ultramobile PCs (UMPCs) and laptops. A large potential market.
There are 57 small- and medium-size panel production lines in the world, four of which are 5G production lines in mainland China.
Companies such as Beijing BOE Technology Group, Catic Shenzhen Co. and Shenzhen Tianma Microelectronics, have recently invested in new 4.5G production lines — the second, third and fourth of its kind in mainland China.
The number of 4.5G TFT LCD production lines in the region is expected to reach 8 or 10 in the next 5 years.
The production line’s low technology barriers and lesser investment capital requirement are said to be the main reason why some TFT LCD makers are paying more attention to 4.5G lines. And, in truth, the growth of the use of devices requiring these smaller screens is big enough to sustain much expansion.
