Sharp Corp. unveiled Monday a new multiscreen display system that has what it says is the world's thinnest frame width, upping the stakes in the growing market for digital signs.

The consumer electronics maker said it will start selling the system, which consists of nine 60-inch liquid crystal display monitors separated by frames only 6.5 mm wide, on Aug. 31 in Japan.

Based on an in-house study, Sharp said the width is the world's narrowest in terms of LCD monitors that are 46 inches or larger.

Fujikazu Nakayama, Sharp's group general manager for business solutions, said the new product can make the images look more connected and offer better presentation on large wall displays and digital signs in such places as train stations, airports and shopping malls.

Sharp officials said they are looking at a retail price of about ¥50 million for the entire system, which consists of nine display panels.

The panels make use of light-emitting diode backlights and can be used in auto showrooms.
