LED segment display is one of the commonly used display screens. By inputting the corresponding current to its different pins, it will light up, so as to display the number, date, temperature, and so on.
Because of its relatively low cost and simple use, it is widely used in the fields of electrical appliances, especially household, such as air conditioners, water heaters, refrigerators, and so on.
LED segment displays are composed of many SMD LEDs mounted on the circuit board and plastic shell to display fixed and simple numbers and other information patterns. The most common forms are the numbers 0 to 9, one or two decimal points, alphabet, marks, and symbols.
The shell is made of flame retardant PC plastic, with high strength, impact resistance, aging resistance, UV protection, dust prevention, and moisture resistance. LED segment displays have the advantages of low power consumption, low heat, impact resistance, and long serving time. With the help of a controller, it can realize the effects of running water, gradual change, jump, and chase, etc. It can be divided into common cathode and common anode according to the attribution. A wide range of colors are available: white, red, green, blue, orange, etc.
With the development of technology, it is supposed to be replaced by segment LCD display in some areas. If we compare it with segment LCD display, it is much cheaper and much brighter, suitable for industrial illumination and indication, but low class and much thicker.
