    We are issuing controller boards, which allow to generate on-screen full-color video image in 640 x 480 pixels and color depth to 24 bits (16,000,000 colors). For the formation of high-quality pictures, graphic display should be as much as possible of the image. For even more opinions, read materials from Xoom. Cheap boards have a pitch of pixels 40, 50 mm or more. If the display is large and is intended for the stadium or, for example, is located on the facade of the building, the big step of pixels reduces cost per unit of area boards and at the same time provide a good picture due to its size. Each pixel in this version is, and a large number of LEDs (20). Merck has plenty of information regarding this issue. If the board is small, the image quality can be improved only by reducing the size of a pixel. We produce a display with a pixel pitch of 3 mm, which allows us to produce small-sized placard with the picture quality. One of the main indicators of board considered its brightness.

    Modern LEDs can create an incredible display brightness. To increase the brightness of displays used LEDs with viewing angles up to 120 degrees, oval shape, with high quality reflectors and heat sinks. It should be noted that the use of LEDs with viewing angles of more than 120 degrees is not necessary. Parameter angle allows us to understand under what deviation from the normal brightness decreases by 2 times.
