Sharp Corp. will begin production of three types of IGZO [indium gallium zinc oxide] LCD panels that boast pixel densities among the highest in the industry. The new displays will be used on various 11.6” – 15.6” laptops and will bring the display quality never-before-seen in the industry. At present it is unclear which notebook maker will use the panels.

These LCD panels are intended for use in notebook PCs and will come in three sizes: 11.6”, 14”, and 15.6”. Production is scheduled to begin in June 2013 at Sharp's Kameyama Plant No. 2. This new production allows Sharp to expand its lineup of IGZO LCD panels for notebook PCs, with the company having already started production of 13.3” IGZO panels.

IGZO technology enables smaller thin-film transistors and increased light transmittance. As a result, fine text can be rendered crisply and clearly, and images can be displayed with impressive realism. For example, the 14-inch panel boasts a pixel density of 262 ppi, which represents 1.67 times the number of pixels of full high definition. Increased light transmittance also means lower rates of energy consumption, with IGZO technology reducing the amount of power required to drive liquid crystals during the display of still images. These factors lead to greater energy efficiency and longer battery life on notebook PCs. IGZO technology is also compatible with stylus-input touchscreen functionality.

Sharp will work to further expand the range of applications using its IGZO LCD panels in products such as smartphones, tablet PCs, notebook PCs, and 4K displays that make the most of the super high resolution and energy efficiency of these panels.
