The LED display is a display device consisting of an array of light emitting diodes. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, less failure, large viewing angle and long visible distance.

     The working principle of the LCD display is to use the physical characteristics of the liquid crystal: the arrangement becomes orderly when energized, so that the light can easily pass; when the power is not energized, the arrangement is disordered, and the light is blocked, so that the simple point is to block the liquid crystal like a gate or let the light pass. through.

     Optional LCD basic pointer: high brightness, the higher the brightness value, the picture is naturally brighter, will not be unclear; high contrast, the higher the contrast, the more vivid colors, and the stereoscopic appearance; the wide visible range, on the screen The larger the clear range of the front screen can be seen, the easier it is to see; the fast signal response time, after the system receives the keyboard or mouse indication, the CPU calculates and processes, the faster the reaction to the display, the easier the job processing
