LED dot matrix display can achieve ultra-high density: indoor up to 62.500 dots per square meter (P4). Good color mixing: Red particles, pure green particles and blue particles are fully mixed together by using the miniaturization of light-emitting devices and the wave-particle duality of light.
Excellent antistatic performance: the production environment has strict standards and the insulation design of product structure. Strong reliability: Compared with SMD and LEDLAMP, LEDDOT-MATRIX has excellent flatness and aesthetic feeling. Wide viewing angle: 140 degrees (horizontal direction)
High permeability: The new generation of lattice technology has achieved nearly perfect permeability by virtue of the high purity of the wafer itself and the epoxy resin material with near 100% light transmittance. High brightness: Compared with 0603 or 0805 vertical stickers, LED can reflect more luminous flux, and it is a utility model patent at present; 4×4 module form, which can realize 1/4 scanning and further improve the brightness.

Characteristics of dot matrix backlight technology for TV sets;
LED lattice has the characteristics of high brightness, low power consumption, few pins, large viewing angle, long life, moisture resistance, cold and heat resistance, corrosion resistance and so on. There are two kinds of dot matrix displays: monochrome and bicolor, which can display red, yellow, green and orange. There are 4×4, 4×8, 5×7, 5×8, 8×8, 16× 16, 24×24, 40×40 LED lattices.
According to the number of pixels, it is divided into equal, double primary colors and three primary colors. According to the different colors of pixels, the colors of displayed text, images and other contents are also different. Single primary color dot matrix can only display fixed colors such as red, green and yellow.
The color of dot matrix display content of double primary colors and three primary colors is determined by the lighting combination mode of different color LEDs in pixels. For example, when both red and green are turned on, yellow can be displayed. If the light-emitting time of the diode is controlled according to the pulse mode, the gray scale display of 256 or higher can be realized, that is, the true color display can be realized.
