An LED display, or light emitting diode display, is a flat panel display that uses light emitting diodes as the video display. An LED display panel can be either a small display or part of a larger display. LED diodes are used in order to make up an LED display. LED displays are also used in billboards and store signs. An LED panel consists of several LEDs, whereas an LED display consists of several LED panels. LEDs used in order to make up LED displays offer several advantages in comparison to other light emitting sources. A light emitting diode is made up of a semiconductor chip which is surrounded by a transparent plastic case. The plastic case allows the light to pass through it. The emission of different colors including ultraviolet and infrared light depends on the semiconductor material which is used in the diode.
Types of LED Displays
LED displays are often found outdoors in billboards and store signs. They can also be found in destination signs on public transportation vehicles or as part of transparent glass area. LED panels can either be used for lighting or for general illumination, task lighting or stage lighting. LED displays can be found in sports stadiums, public squares, train stations, airports, highways, commercial plazas, subways, parks, shopping centers, on tall buildings and for corporate image promotion and advertising. Due to the far viewing distances in sports venues, the high brightness of LED displays can meet this special requirement and ensure that viewers get clear images.
