5.7 Other LED Shapes
LEDs are also available in different shapes and sizes. Figure 5.6 shows an LED assembly in the form of a bar, housed in a DIL package, and is available in different colours.
Figure 5.7 shows an LED dot-matrix assembly consisting of 5 rows and 7 columns of LEDs arranged as dots, and housed in a 14-pin DIL package. This type of dot-matrix LEDs is available in various colours, sizes and shapes. Several such LED assemblies can be connected to each other and a microcontroller is commonly used to display characters or symbols on the LED assembly.
LED dot-matrix displays are also used as large fixed or moving displays, usually in advertisements, or as signs. An example large display is shown in Figure 5.8.
