3. Grayscale of Outdoor Front Maintenance Led Display
According to the colour of LEDs used, Outdoor Front Maintenance Led Display can be divided into the single base colour, double base colour and full-colour screen. Monochrome LED display can be used as a text display, each pixel with a single-colour LED, most of the red; dual-base colour LED display can be used as a graphic display, each pixel is composed of red and green LED tube, can be realistic red, green and yellow colour display; full-colour LED display can be used as a video display, each pixel is composed of red, green and blue LED tube, the display colour is delicate.

Generally, according to the simplified formula "the best visible distance = point spacing / (0.3 ~ 0.8)" to estimate, for example, with P16 display, point spacing of 16mm, the best viewing distance of 20-54 meters.
Grayscale is an important indicator to measure the display effect of Outdoor Front Maintenance Led Display. The grayscale is determined by the number of analogue-to-digital conversion bits with the support of other supporting hardware, and there are three mainstream ones: 8-bit, 10-bit and 16-bit. =16777216 kinds of colour changes, that is, the commonly said 16M colour; 10-bit modulus conversion corresponds to 1024 kinds of luminance changes, that is, 1024 levels of grey, a total of 1024 × 1024 × 1024 = 1073741824 kinds of colour changes, that is, the commonly said 1.07 billion colours. The higher the grayscale level, the better the display effect.
