New 4.8-inch model is the world’s smallest full HD LCD screen

A new high-definition LCD display made by a joint partnership between Casio Computer and Toppan Printing has yielded a new 4.8-inch device. The new LCD is now the smallest full HD display, with other small screens still unable to provide HD support the same way this screen can.

The new technology is a 1920 x 1080 pixel Hyper Amorphous Silicon TFT (HAST) LCD screen that includes a solid 160-degree viewing angle. The screen has a 458ppi pixel density and includes 16.8 million colors, however, additional details remain sketchy about the LCD.


The LCD is manufactured by Ortustech and the technology will be used to manufacture small and mid-sized LCD displays. The popular Apple iPhone has 326ppi with 960 x 640 resolution. The 4.8-inch size may seem a bit too big for a smartphone or a personal media player, but it could be heavily utilized in next-generation smartphones and tablet devices.

Although this new screen from Ortustech offers a promising view of what we can expect around the corner, it’s unlikely we’ll see this screen in consumer products any time soon. Companies are in a race to show off their latest and greatest LCD screen technology, even if it’s years away from wide release.

The cost of the screen will also remain high, so it’s unlikely we’ll see this screen in products anytime in 2011.


LCD technology continues to develop at a fast pace, with Casio recently introducing a 2.2-inch HAST TFT LCD screen yielding 640×480 resolution. Similar to what is expected from this newer model, the smaller, older 2.2″ screen was used by digital cameras and select other consumer electronics.
