■ Development Background

Changing the common sense of "large display = expensive"

Until now, large displays have typically been achieved by:

Arranging multiple LCD displays side-by-side
Using projectors that require a dark room

However, many challenges existed such as:

Bezels (frames) are noticeable
Difficult to see in bright rooms
Maintenance and lifespan issues

The SHISAI 4K LED Display was developed with the goal of solving these problems at once and "fundamentally changing the quality of a space with a single unit."
