All about LED Panels and Displays

LED (Light Emitting Diode) is a special type of diode that has the property to convert the electrical energy into light energy. It acts a highly efficient source of light and thus finds applications in various appliances and electronic components. LEDs are popularly used as LED displays in our homes and outdoors. LED is everywhere from our mobile to large LED displays.

Different Types of LED Panels

An LED panel consists or an array or group of LEDs powered by electrical source of energy. LED panels can be broadly classified into two categories, surface mounted panels and conventional LED panels. Conventional LED panels are most commonly used in large outdoor. It consists of LED in discrete forms that are separated from each other as individual units. The complete display that you get on the screen is the combination of information stored in square shaped individual displays called pixels. Some of the examples are Moving message LED display that you must have seen in malls, stores and buildings. LED message displays also use conventional LED panels that display static message.

Full Color Transparent LED displays make use of SMD technology that is significantly different from the conventional LED panels that displays information in the form of pixels. Full Color Transparent Displays produces display by the combination of red, green and blue lightings. The pixels are very fine as small as the size of pin head, thus producing extremely sharp display. These pixels are mounted on the circuit boards and compact chips. These chips are packed in the transparent plastic casing that provides protection to the circuitry and also allowing the produced light rays to pass. The illumination produced by full color transparent display is not very bright to be viewed from a very long distance. Large LED displays find applications in stadiums and business organizations. The use of LED displays is not just limited to large displays but also in small electronic devices such as mobiles and watches.

Working of LED

A diode is a p-n junction device consisting to two terminals, p and n connected to positive and negative supply respectively. The electrons coming from one side combine with holes to produce energy that is released mainly in the form of photon or light. The color of the emitted photon depends on the wavelength of the produced light which in turn depends on the type of semiconductor material used to manufacture LED.
