Sharp wants to revolutionize the display industry with their IGZO based panels. Sharp has unveiled their first OLED panels, including a 4K OLED and a flexible, high-resolution 3.4 inch OLED. Sharp has also developed extremely high-resolution LCDs, including a 6.1 inch LCD with 2560x1600 pixel resolution. All this has been made possible with IGZO.

Sharp reveals first OLED panels

Sharp has revealed their first OLED panels ever and they are extremely promising. The panels have been produced utilizing Sharp’s IGZO TFTs that enables Sharp to create extremely high-resolution display panels (both LCD and OLED).

The first OLED panel measures 13.5 inches and is designed for laptops. It has an impressive resolution of 3840x2160 pixels often referred to as 4K. Pixel density is 326 ppi (pixels per inch) and it is based on white OLEDs with color filters. This is extremely impressive, especially because it is Sharp’s first OLED prototype. Other manufacturers have struggled with producing high-resolution OLED panels but Sharp seems to have overcome that issue with IGZO, signaling the potential of IGZO based TFTs and production.

Sharp has also unveiled a 3.4” flexible OLED. Unlike most flexible OLED panels produced to date, Sharp has managed to create a flexible OLED panel with extremely high resolution. With its 540x960 pixels it has the same high 326 ppi density as the 13.5 inch panel or similar to Apple’s iPhone 4S.

High-res LCDs also unveiled

Sharp highlights two new high-resolution LCD panels for mobile devices. The first one is a 4.9-inch smartphone LCD display with 720x1280 pixels or 302 ppi. The second one is even more impressive. It is a 6.1-inch LCD panel with 2560x1600 pixel resolution or 498 ppi.

Sharp will exhibit all of the panels at the SID 2012 conference in Boston this week. No plans to mass-produce the panels have been announced at this point but Sharp says that if the demand is there for the new OLED panels, they will start production.
