Sharp 5-inch 1920×1080 LCD

Sharp: Japan’s largest LCD supplier announced manufacturing commencement of its 5-inch 1920×1080 LCD at its Mie Plant No. 3. The resolution of 443 ppi is, I think, the highest for any display that is currently in production.

Sharp is using continuous grain silicon (CGS) as the material for the thin film transistors (TFT) instead of its oxide semiconductor-based IGZO. IGZO might be the new thing by Sharp but when it comes to electron mobility it is in the middle of amorphous silicon (a-Si) and low temperature poly-silicon (LTPS). LTPS is fast, but CGS is even faster: 3x the electron mobility of LTPS. With a resolution of 443 ppi electrons need to move around faster for a flicker-free visual experience and CGS gets the job done better than LTPS, IGZO, or a-Si.
