With the development of the market economy, the application of LED display will continue to expand. LED display as a new information dissemination tool, in all walks of life has shown the advantages of LED display. LED display light-emitting diodes of longer life, lower power consumption, and higher brightness characteristics and is destined to make it the preferred species of large-screen information display applications. But at present, some people do not know much about the difference between outdoor LED display and indoor LED display, we explain the difference between the two below.
Led display according to the use of the environment can be divided into the indoor led display, semi-outdoor led display and outdoor led display.
Indoor led display, as the name implies, is the display installed indoors, and also contains small pitch led cob, and micro pitch led display.
Semi-outdoor refers to led installed in an outdoor sheltered place for information dissemination, suitable for commercial storefront advertising media. Pixel point size between indoor and outdoor LED display; commonly used in banks, shopping malls or hospitals, etc. on the lintel. Semi-outdoor LED display has high luminous brightness and can be used under non-direct sunlight outdoor, the screen body has a certain seal, generally installed under the eaves or in the window.
Outdoor led display only fully exposed to the outdoors, generally used in government, schools, shopping malls, advertising, transportation and other various industries.
Difference one, the production process
The indoor screen production process is the first light-emitting grain into a dot matrix module (or digital tube), and then the module is spliced into a certain size of the display unit board, according to the application requirements, the display unit board as the basic unit spliced into the size required for the application.
Outdoor screen in the production process is the first light-emitting grains encapsulated into a single LED, called LED single light. The LED single light used to make outdoor screen generally adopts a reflector with a light-gathering effect to improve the brightness; then multiple LED single lights packaged into a single pixel tube or pixel module, and the pixel tube or pixel module constitutes a dot matrix display unit box, according to user needs and display application sites, a display unit box as the basic unit to form the required size. The box should be sealed in the design to achieve the purpose of being waterproof and fog proof so that it can adapt to the outdoor environment.
Difference two, viewing distance
Indoor conventional led display point spacing of 2mm, 2.5mm, 3mm, 4mm, outdoor led display point spacing of 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 16mm. indoor display point spacing is small, the more pixels in the unit area, the clearer the display picture quality. Of course, the price is also higher than the outdoor ones.
Different dot pitch also affects the viewing distance. The higher the pixels, the clearer the display, and the larger the information capacity, so the closer the viewing distance. Outdoor pixel density is not as high as indoor pixel density, because of the specific distance of observation, so the pixel density is low and the dot pitch is larger than indoor.
Difference three: Brightness
How to adjust the brightness of the display screen has a greater impact on the screen, too low to show the screen dark, too high brightness both eye and power consumption. Therefore, we must choose a suitable brightness led display according to the environmental conditions.
Indoor light is lower compared to outdoor, so the brightness does not need to be too high, generally, about 600cd/m2 can be, outdoor string light led to the outdoor LED display brightness requirements being higher. Outdoor LED display is generally placed in the sun by direct sunlight. If the brightness is not handled well above, or reflections and other situations occur, the viewing effect will definitely be affected. Outdoor led brightness in the 3000-6000cd/m2 or so.
Difference four, the use of the environment
Indoor LED display because the use of the location generally does not need to have waterproof, fire and other requirements, while outdoor LED display because of the diversity of the use of the environment on the adaptability of the product in a variety of environments presents a challenge. Outdoor LED display is after combining the results of research on the external environment applied to the preliminary design and later maintenance and repair of the resulting system. Mostly used in large outdoor plazas, such as government plazas, leisure plazas, commercial centers, advertising information release boards, commercial streets, train stations, etc. Indoor LED display relative to the outdoor environment to be much better, not affected by high temperature, for waterproofing there are no special requirements, indoor LED display for air humidity has high requirements, in the southern region of China encounter back to the south of the season need to strengthen ventilation measures, to maintain a dry environment before and after the indoor LED display screen body.
NSE supply the portable LED sign, LED traffic display, which include taxi top LED display, bus LED display, LED arrow board, variable message sign(VMS), VMS trailer display,etc.All the LED products from NSE are with best quality, technology and price.
