The Difference Between Indoor LED Display And Outdoor LED Display

2023

You may know that LED displays are installed and controlled in different ways, but the most critical difference is indoor and outdoor. This is the first and most important step in choosing an LED display, and it will determine how you choose an LED display in the future. So how to distinguish between indoor and outdoor LED display? How should we choose?

1. What is an indoor LED display?

Indoor LED display refers to the LED display used indoors. For example, large-scale led display screens in shopping malls, large-scale broadcast led screens in stadiums, etc. These devices are everywhere. The size and shape of the indoor LED display is customized according to the buyer's idea. Due to the small pixel pitch of the indoor LED display, the quality and clarity of the LED display are relatively high.

2. What is an outdoor LED display?

Outdoor LED display refers to the LED display used outdoors. Due to direct sunlight or long-term exposure to sunlight, the brightness of the outdoor LED display will be higher. In addition, since outdoor LED advertising displays are usually used in large areas, their area is generally much larger than indoor led displays.

In addition, there are semi-outdoor LED displays for outdoor LED displays, which are generally installed at the door for information release and used in advertising media in retail stores. The pixel pitch is between indoor and outdoor LED display. It is often used in front of banks, shopping malls or hospitals. Due to the high brightness, the semi-outdoor LED display can be used outdoors without direct sunlight. Due to the good sealing performance, the LED display screen body is generally installed under the eaves or under the windows.

3. How to distinguish the outdoor led screen from the indoor led screen?

For users who don't know much about LED displays, there is no other way to distinguish between indoor LED displays and outdoor LED displays except to look at the installation position of the LED display.

I have summarized some differences between indoor and outdoor LED displays, which can help you better distinguish.

1) waterproof

Because the indoor LED display is installed indoors, there is no waterproof measure.

The surface of the outdoor LED display must be impervious to water. There are many outdoor LED displays installed in places that cannot be sheltered by wind and rain. Therefore, outdoor waterproofing is essential.

2) brightness

Indoor LED display brightness is low, generally 800-1200cd/m2. Since there is no direct sunlight in the room, the brightness requirement is not very high.

Outdoor LED display brightness is relatively high, generally around 5000-6000cd/m2. Since the outdoor is exposed to direct sunlight for a long time, it must have a high brightness to see a clear LED display in the sun.

Reminder: The indoor LED display cannot be used outdoor, because the brightness is too low to see anything. Similarly, outdoor LED displays cannot be used indoor. Because the brightness is too high, it will hurt the eyes.

3) Pixel pitch

The viewing distance of indoor LED display is relatively short, so there are corresponding requirements for the picture quality and clarity of the LED display. The pixel pitch of the indoor LED display is small. The smaller the dot pitch, the better the picture quality and clarity of the LED display.

The viewing distance of the outdoor LED display is relatively far, so the picture quality and clarity of the LED display are not so high. The pixel pitch of outdoor LED display is generally larger.

4) Appearance

Indoor LED displays are commonly used in places of worship, restaurants, shopping malls, workplaces, meeting spaces, and retail stores. Therefore, the usable indoor led screen cabinet will be smaller.

Outdoor LED displays are usually used in large places such as football fields or highway signs, so the outdoor LED display cabinet is larger than the indoor cabinet.

5) Adaptability to external weather conditions

In terms of adaptation to weather conditions, indoor LED displays are different from outdoor LED displays.

The indoor LED display is installed indoors and is not affected by the weather. Therefore, in addition to the IP20 waterproof rating, there is no need to take any protective measures due to changes in external weather conditions, so there is no such function.

The outdoor LED display is designed to fully adapt to various weather conditions. Outdoor LED screens are generally equipped with protective measures such as leakage prevention, dustproof, sunscreen, lightning protection, and waterproof.

4. Do you need outdoor LED screen or indoor LED screen?

"Do you want indoor or outdoor" is a question that LED display manufacturers will definitely ask you, so before answering, you need to know what conditions the LED display you want must meet.

Are you exposed to direct sunlight?

Do you need a high-definition LED display?

Is the installation location indoors or outdoors?

Once these are considered, you can decide whether you need an indoor or outdoor display.

Ensure a protective layer (e.g., paper or carpet) is laid on the ground to avoid collisions with the display lamp surface during.B: During installation, do not use iron tools/hammers to strike the cabinet or employ rough methods such as kicking.C: If the gap between cabinets is too large during installation, use a hard object to pad and ensure parallelism and verticality (note: the gap between cabinets should be less than 0.1mm).Power Supply System TestNote: (The inspection of the power supply in the distribution cabinet and the cabinet power supply must be performed by qualified electricians.)A. Check for short circuits between the Live (L) wire, Neutral (N) wire, and Ground (FG) wire.B. Check for short circuits between the Neutral (N) wire and the Ground (FG) wire. The resistance value should be ∞.C. Check for short circuits between the receiving card +4.2V power supply and GND (30–50Ω) terminals, Ground (FG) wire, Live (L) wire, and Neutral (N) wire. The resistance value should be ∞.D. Check for short circuits between the receiving board GND, Ground (FG) wire, Live (L) wire, and Neutral (N) wire. The resistance value should be ∞.E. Test for short circuits between the +4.2V output and GND of each power supply. The resistance value should be 30–50Ω.LED Display Installation PrecautionsA. After installation, the display screen must be equipped with lightning protection. A surge protector must be installed at the main power input terminal.B. Never perform live operations on the display screen.C. During the fixation of cabinets, ensure they are securely fastened while avoiding collisions that may cause damage to the product.D. Workers must adopt safety measures during installation (e.g., wearing protective helmets, safety harnesses, etc.).E. When removing control system boards or other equipment, take anti-static precautions (e.g., wearing anti-static gloves).Installation InstructionsA. This product is designed for outdoor use. Store it properly before installation.B. To ensure safety, the product must be installed by professional technicians.C. Before installation, disconnect the power supply and check whether the insulation layer of the power cord is intact.D. Ensure the reliability of the product and the installation structure.

Ensure the bracket is stable and the installers are safe to prevent potential risks.F. Grounding must be installed to ensure the safety of personnel and equipment.G. Only professional technicians are allowed to perform repairs on this product.Core Points of Cabinet Installation1. Structural Stability and FlatnessA. Benchmark Positioning: First, determine the center point and reference lines of the display screen. Install the cabinets starting from the center and moving outward to ensure overall symmetry.B. Layer-by-Layer Installation: It is recommended to install the cabinets from bottom to top, layer by layer. After completing each layer, check its levelness and alignment with the steel structure.C. Leveling Tools:Use high-precision tools such as magnetic-mounted laser levels to monitor the flatness of the cabinet surface in real time during installation. Avoid relying solely on visual inspection.D. Even Force Distribution:When tightening the cabinet connection screws, adopt the "diagonal tightening" method. Tighten the screws gradually and in multiple stages to ensure even force distribution between the cabinets and the steel structure, as well as between adjacent cabinets. This prevents deformation caused by excessive stress at any single point.Warning: The horizontal and vertical flatness of each cabinet / each layer must be properly adjusted before proceeding to the next step. Poor cabinet flatness may result in noticeable "dark lines" or "bright lines" (gaps) between display modules, severely affecting viewing quality and making subsequent adjustments difficult.2. Waterproof Sealing TreatmentA. Waterproof Gaskets: After the complete installation or maintenance of the screen, inspect the waterproof gaskets on the rear cover of the cabinets for detachment or deformation. If any abnormalities are found, replace the gaskets promptly to prevent internal water damage to the display.B. Backside Waterproofing: For displays with maintenance access at the back or wall-mounted displays, all maintenance doors and decorative structures must be sealed and waterproofed to prevent long-term corrosion of the screen structure or cabinets by rainwater.3. Heat Dissipation and Ventilation AssuranceA. Ventilation Pathways: During installation, ensure that the air intake and exhaust vents designed on the back of the cabinets are not blocked. Maintain clear and unobstructed cooling air channels.B. Cooling Measures: If the display design includes a backside ventilation pathway, ensure air convection within the channel. Avoid installing the cabinets directly against airtight walls, and leave sufficient space for heat dissipation. Depending on the ambient temperature, additional convection fans or air conditioning may be installed to enhance cooling.Post-Installation Inspection and TestingWarning: After the installation of the display screen is completed and all cables are connected, a comprehensive cable test and inspection must be performed before powering on the system.A. Physical Structure Re-inspection: After the installation of the steel structure and cabinets, recheck all screws to ensure they are properly tightened and verify the stability of all welding points.。B. Waterproofing Review: Carefully inspect all sealed areas to ensure the application is complete, with no missed or interrupted sections.。C. Insulation and Short Circuit Test: Use a multimeter to measure the power input terminals and ensure no short circuits are present.。D. Power-On Test: After supplying power, check whether the cabinet power supply is functioning normally and confirm that all power indicators are lit. (This must be done immediately after powering on to promptly identify any abnormal circuits and prevent potential equipment damage.)E. Troubleshooting: After debugging, display white, red, green, and blue colors on the LED screen to test for any damaged or malfunctioning modules. Replace or repair faulty modules as necessary.Installation Accessories and ToolsGE500 Cabinet / Module IntroductionProduct DimensionsThe GE500 cabinet measures 1000mm in width, 1000mm in height, and approximately 99mm in thickness.The module kit is manufactured using die-cast aluminum integrated molding, with dimensions of 500mm in width, 250mm in height, and 24.15mm in thickness.Each cabinet is arranged with 2 modules in width and 4 modules in height, totaling 8 modules to form a complete cabinet unit.Cabinet / Module Function IntroductionRear View of CabinetCabinet Exploded ViewRear View of ModuleFront View of ModuleStep-by-Step GE500 Outdoor LED Display Installation ProcessSteel Structure InstallationWarning: Before installing the steel structure, clearly mark the safety zone and cordon it off.
