From the application environment classification, LED display can be divided into indoor LED display and outdoor LED display . Different application environments have different hardware and software requirements for LED display . Therefore, when we are doing indoor LED display rental, we can not consider the point of renting outdoor LED display , but should be determined according to the specific situation. So what needs to pay attention to indoor LED display rental lease it indoor LED display, note the following?: First, the brightness Brightness has a great influence on the indoor LED display . If the brightness is too high, it will damage the human body's vision and endanger human health. If the brightness is too low, the display image will be unclear. Generally speaking, the brightness of the indoor LED display is 800cd / m2 -2000cd/ m2, and the brightness of different brand LED display products is also different. Indoor LED display Second, the viewing angle 　　 LED display size determined by the viewing angle of the LED display directly the number of audience. The larger the viewing angle, the better the audience will be, and the viewing angle will be affected by the way the LED die is packaged. Therefore, when choosing an indoor LED rental screen, pay attention to the way the package is packaged. Third, the flatness The flatness of the display affects the quality of the displayed image. The flatness of the surface of the indoor LED rental screen in the industry is kept within ±1mm , and the partial protrusion or recession on the surface of the box will cause the viewing angle of the full-color LED display to appear dead angle. The quality of the flatness is determined by the production process, and LED display manufacturers should pay attention to this problem during production. Fourth, the color reduction The reproducibility of the display on the display means that the color displayed on the display should be consistent with the color of the source to ensure the realism of the image. Five, the dead point The dead point of the outdoor LED display is to indicate a single point on the display that is always bright or always black. The number of dead points is mainly determined by the quality of the die. The lower the dead point, the better the display will be. The Schottky Diode is another type of semiconductor diode which can be used in a variety of wave shaping, switching and rectification applications the same as any other junction diode. The main adavantage is that the forward voltage drop of a Schottky Diode is substantially less than the 0.7 volts of the conventional silicon pn-junction diode.
Schottky diodes have many useful applications from rectification, signal conditioning and switching, through to TTL and CMOS logic gates due mainly to their low power and fast switching speeds.
the Schottky Diode also known as a Schottky Barrier Diode is a solid-state semiconductor diode in which a metal electrode and an n-type semiconductor form the diodes ms-junction giving it two major advantages over traditional pn-junction diodes, a faster switching speed, and a low forward bias voltage.

The metal–to-semiconductor or ms-junction provides a much lower knee voltage of typically 0.3 to 0.4 volts compared against a value of 0.6 to 0.9 volts seen in a standard silicon base pn-junction diode for the same value of forward current.
Variations in the metal and semiconductor materials used for their construction means that silicon carbide (SiC) Schottky diodes are able to turn [ON" with with a forward voltage drop as little as 0.2 volts with the Schottky diode replacing the less used germanium diode in many applications requiring a low knee voltage.
