ことも大画面化ケ妨たける接置の一つとなっている。Traditionally, high-resolution, full-color, large screens (3 to 20”
There was no suitable Tisgelley device for 2). Furthermore, if you try to obtain a large screen using a liquid crystal display and achieve full color, the liquid crystal must be driven statically, and the number of drive elements would be on the order of several tens of blades. Furthermore, even if this element is integrated into an IC, the elements on the side of several blades are polished, which is one of the factors that hinders the development of larger screens. Furthermore, the number of conductors at the output terminal of the liquid crystal is in the hundreds of thousands, which is one of the obstacles to increasing the screen size.

A large screen is created by installing a printed circuit board with a large control circuit on both sides of the display and approximately at the inner corner, and by arranging a large number of liquid crystal displays side by side.
