Dot Matrix

The LED matrix module is a very useful and low-cost way to add a display to your electronic circuits. It has 16 pins to achieve a different combination to ON/OFF the LEDs. It fits properly into any standard solderless breadboard. It is a Great display for electrical and test equipment. The diameter of the Led is about 1.9 mm with a common Anode configuration which emits Red color.  The Exact dimensions of this module are shown in the Schematic image.

These Displays are always in high demand in the DIY community as well as in  Industrial Projects due to their multipurpose uses and cheap cost.

A dot-matrix display is a low cost electronic digital display device that displays information on machines such as clocks,
watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.

The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration
(other shapes are also possible, although not common) such that by switching on or off selected lights, text or graphics can be displayed.
These displays are normally created with LCD, OLED, or LED lights and can be found in some Thin Film Transistors.

The Thin Film Transistors had an active display which allows the dot matrix to display different pixels with different colors at the same time.

A dot matrix controller converts instructions from a processor into signals that turn on or off indicator elements in the matrix so that the required display is produced.

A common size for a character is 5×7 pixels, either separated with blank lines with no dots (in most text-only displays), or with lines of blank pixels (making the real size 6×8). This is seen on most graphic calculators, such as Casio calculators or TI-82 and superior.

A smaller size is 3×5 (or 4×6 when separated with blank pixels). This is seen on the TI-80 calculator as a “pure”, fixed-size 3×5 font, or on most 7×5 calculators as a proportional (1×5 to 5×5) font. The disadvantage of the 7×5 matrix and smaller is that lower case characters with descenders are not practical. A matrix of 11×9 is often used to give a far superior resolution.

Dot-matrix displays of sufficient resolution can be programmed to emulate the customary seven-segment numeral patterns.
A larger size is 5×9 pixels, which is used on many “natural display” calculators.
