Sharp Corp. said late on Wednesday that it would initiate mass production of IGZO LCD panels for smartphones at its 8th generation Kameyama Plant No. 2 within this year. IGZO technology will enable ultra-high pixel densities and resolution beyond full-HD on smartphones and tablets.
The two main advantaged that liquid crystal displays with indium gallium zinc oxide (IGZO) active layer have over conventional LCDs with amorphous silicon are either very small pixels or very high reaction speed. Using IGZO technology, manufacturing of ultra high-definition displays much easier compared to traditional ways.
Last year Sharp showcased 6.1” display with 2560*1600 resolution and 498 pixels per inch density. While this particular screen will probably be aimed at limited edition superphones as well as professional applications, normal-sized monitors with ~500ppi density could feature resolutions like 12800*7200, 13440*7560 or 7680*4320 (which is currently known as super hi-vision or SHV).
At Kameyama Plant No. 2, which went online in August 2006, Sharp has been using large, 8th generation glass substrates in the highly efficient production of LCD panels for big-screen TVs. Having introduced IGZO display technology in March 2012, Sharp has since been producing small- and medium-size LCD panels for tablet and notebook PCs as well as larger LCD panels for high-resolution LCD monitors.
Using 8th generation glass substrates, Sharp will be the first company in the world to achieve commercial production of high-definition IGZO LCD panels for smartphones. The highly efficient production levels achievable with 8th generation glass substrates will be made possible by an optimized production process as well as by IGZO technology's ability to enable smaller thin-film transistors and increased light transmittance.
Sharp will work to meet vigorously growing demand for LCDs in the smartphone market by taking advantage of the energy efficiency, super-high resolution, and high-performance touchscreen functionality of its IGZO LCD panels. Furthermore, Sharp will continue to expand the range of applications of IGZO in products such as tablet PCs, notebook PCs, and 4K displays.
