![]() ![]() Typically, they are used to display traffic information at bus stands or railway stations. ![]() They include outdoor, large, single column LEDs or double LED displays. It is used to display characters and image information.Ĭonventional LED displays: These typically require a steel structure to install an LED display at a particular place. LED lattice image text display: This lattice display module is made up of many even-array LEDs. ![]() Digital display: This is a seven-segment digital Nixie tube, used in clock displays, interest rate screens and other digital displays.Image display: This is a double primary LED display screen.Text display: This is a single primary LED display screen.display video, animation and other video files.Video display: This is a full colour LED display screen.Usually, it can’t display many grayscale colours, and is mostly used to display characters. The images are edited in the PC and transmitted to an LED display (where they get auto-played) via a serial interface or other network interface. In the case of asynchronisation, an LED display can store and auto-play the characters and non-grayscale images. It can display many grayscale colours, which can achieve the effect needed in multimedia advertising. Synchronised and unsynchronised displays: Synchronisation is the working mode of an LED display, which is similar to a computer monitor. ![]() These can display white balance and 16,777,216 colours. Screens with three primary colours offer red, blue and green LEDs. LED displays with double primary colours are made up of red and green LEDs. In this case, the display body is sealed, and is usually installed under the eaves of a building or in a window.ĭisplays with a single colour, double primary colours and three primary colours:Single colour displays are based on the lighting material, the most commonly used being the single red colour, and on some special occasions, yellow and green. The semi-outdoor displays (which are placed in environments that are a mix of the outdoor and indoor) have ultra-high brightness and can be used in sunlight, though not directly. The display cabinet should be able to withstand environmental conditions like wind, rain, lightning, etc. Also, these displays need to be seen from a much longer distance. For outdoor displays, dot density is relatively sparse and brightness requirements are different since viewing conditions vary during the night and during daylight hours. They are also lightweight and have a high density. Since such displays will be viewed from close by, they have a wide visual angle. Indoor and outdoor displays: For indoor environments, the display brightness required is moderate. They provide high visibility and can be easily fixed on different kinds of structures like buildings, hoarding boards, shop windows, etc. Outdoor LED display screens are a popular medium to carry commercial advertisements and various types of information for the public. LED displays can be divided into many categories, based on their type, shape and size. In recent years, LED displays have evolved rapidly, mainly because of their many advantages like high brightness, low forward voltage, low power consumption, easy large scale installation, long life span, impact resistance and stable performance. ![]()
