What is LED Numeric Display?
It is electronic display device for displaying decimal numeralsï¼
LED display screen is an electronic display screen composed of LED dot matrix. The display content forms such as text, animation, picture and video are changed by turning on and off the traffic light beads, and the component display control is carried out through modular structure. It is mainly divided into display module, control system and power supply system. The display module is composed of LED light dot matrix to emit light on the screen. The control system realizes the conversion of the content displayed on the screen according to the light off condition in the control area. The power supply system converts the input voltage and current to meet the needs of the display screen.
LED screen can realize the transformation between different forms of various information presentation modes, and can be used indoors and outdoors. It has incomparable advantages over other display screens. With the characteristics of high brightness intensity, low power consumption, low voltage demand, small and convenient equipment, long service life, impact resistance and stability and strong resistance to external interference, it has developed rapidly and is widely used in various fields.
The luminous color and luminous efficiency of LED are related to the material and technology of making LED. At the beginning, the lamp ball is all blue light, followed by phosphor. Different light colors are adjusted according to the different needs of users. There are four widely used colors: red, green, blue and yellow. Due to the low working voltage of LED (only 1.2 ~ 4.0V), it can actively emit light and has a certain brightness. The brightness can be adjusted by voltage (or current), and it is impact resistant, vibration resistant and long service life (100000 hours). Therefore, there is no other display mode comparable to LED display mode in large display equipment.
7 segment led display, LED, light emitting diode (abbreviation for light emitting diode). It is a diode made of gallium (GA) and arsenic (as), phosphorus (P), nitrogen (n) and indium (in) by controlling the display mode of semiconductor light-emitting diodes. When electrons and holes are combined, it can radiate visible light, so it can be used to make light-emitting diodes. It can be used as an indicator light in circuits and instruments, or form a text or digital display. Phosphorus gallium arsenide diode emits red light, gallium phosphide diode emits green light, silicon carbide diode emits yellow light, and indium gallium nitrogen diode emits blue light.
