LED character and numeric displays are essential components in electrical and electronic application fields. They come in various form factors, like single digit LED displays, alpha numeric LED segments and more.

812 is a type of LED display module which is usually used in industrial applications. It is a 15 segment single digit LED display module and is known for its characteristic red colour.

The 812\'s application fields are quite extensive, ranging from factory automation, process control, and medical equipment to traffic light control systems, scoreboards, and even in automotive instrumentation systems.

As far as working principle of the 812 is concerned, it is fairly straightforward and simple. It consists of a single segment with a red LED at its centre, which is connected to a resistor and the power source. This LED then emits a bright red light, which is used to display data or information.

The 812 display module is accompanied by a controller which is programmed to control the display. This controller reads the data from memory, which can be an ADC, a UART, or an EEPROM, and passes it to the display module as a series of instructions. The instructions received by the display module are then interpreted by it and the corresponding LED segments are turned on, thus resulting in a visible display on the 812 module.

Since the display module is fairly compact in size and the display is bright and clear, it\'s an ideal choice for applications which require a low-power, reliable visual display. Moreover, it is also relatively inexpensive, making it a preferred option for many manufacturers.

All in all, the 812 series display module is a great choice for anyone looking for a reliable, cost-effective way of displaying data and information. With its bright display and low power consumption, it\'s a great choice for any application field.
