This chain type LED display---LumixxLine integrates three kinds of LED chips of red (R), green (G) and blue (B) in one package, and these 3-in-1 LEDs are arranged at 35mm intervals or 70mm intervals. Connected into one column, you can arrange the faces horizontally like a curtain. The number of LEDs per pixel (pixels) is 96, and one control unit can control 16 columns. The control unit can be connected in series up to a maximum of 144 columns, that is, 96 pixels × 144 pixels.
Considering the relationship between flexibility and the LED backplane, the pixel spacing is a minimum of 35 mm, and it is said that if the spacing is too small, the flexibility is lowered, and the difference between the product and the flat display is blurred. However, it is also possible to increase the resolution by a factor of 2. As long as the pixel chains are misaligned into a brick wall, the pixel spacing can be halved. The developer also said that the image processing software used in this LED display also took this configuration into consideration.
The screen size calculation of the display is 20m2 (equivalent to 252-inch display screen) when it is 35mm interval column (corresponding to 252-inch display screen); 74m2 (equivalent to 490-inch screen) when 70mm interval column (1 length is 7324mm). The display can display video in places where conventional flat LED displays are difficult to set up. For example, the LED display is wrapped around a cylinder, laid on a stairway, or hung on a shop window like a "hanging curtain."
