1. What is indoor LED screen display?
As the name suggests, an indoor LED display is designed specifically for indoor environments. Its working principle is based on arranging high-brightness LED lamps in a precise and orderly pattern on a PCB board, while the back of the PCB is equipped with driver ICs and other electronic components. Through accurate control by the LED display system, the indoor LED screen delivers delicate, high-quality visual performance. To help you understand it better, we explain the key points below.
1.1 Brightness Level
Indoor LED displays are typically installed in indoor environments, where a brightness level of around 600 cd/m² is commonly used. For special applications or areas with stronger ambient light, we can customize higher brightness levels—ranging from 1000 to 1500 cd/m²—to ensure an optimal viewing experience.
1.2 pixels pitch
Because indoor LED displays require higher image quality, smaller pixel pitches are typically used for indoor applications. Pixel pitch refers to the distance between two adjacent LED pixels. The smaller the pixel pitch, the sharper, more detailed, and higher-resolution the image will be. For indoor environments, models below P4 are commonly selected. Typical indoor pixel-pitch options include P4, P3.076, P2.5, P2.0, P1.86, P1.53, P1.25, P0.9, and P0.6.
1.3 Protection rating
Indoor LED displays typically feature an IP31 protection rating. For special applications requiring enhanced moisture or water resistance, we can apply nano-coating technology to achieve a higher waterproof level. Alternatively, GOB (Glue on Board) technology can be used to provide even stronger protection and durability.
1.4 Cost
The cost of an LED display depends on factors such as materials, resolution, and screen size. Indoor LED displays tend to be more expensive because they require a higher number of LED lamps. Likewise, indoor screens with higher resolution also come at a higher price. Since each customer’s application scenario and requirements vary, the final cost will differ accordingly.
2.Advantages of Indoor LED Displays
Indoor LED displays offer a wide range of benefits that make them an ideal choice for modern indoor environments. Their advanced technology and flexible design allow them to deliver superior performance across various applications, from business to entertainment. Key advantages include:

Indoor LED displays feature smaller pixel pitches, which provide higher image quality and meet the demands of detailed visuals. They are also ideal for photography and videography. Equipped with high-refresh-rate driver ICs for indoor use, these displays deliver a smoother viewing experience and produce clearer results when captured on camera.
2.2 Vibrant Colors and Excellent Brightness
LED pixels feature high brightness and high contrast, enabling indoor LED displays to present vibrant and colorful images even under various indoor lighting conditions. The high contrast also ensures finer, more detailed visuals, allowing these displays to adapt seamlessly to a wide range of indoor environments.
2.3 Seamless Splicing and Flexible Sizing
The modular design of indoor LED displays allows for seamless splicing and adapts to a variety of installation sizes. Whether for small conference rooms or large exhibition halls, these displays can be easily configured to meet different spatial requirements.
2.4 Wide Viewing Angle
Indoor LED displays offer ultra-wide viewing angles, ensuring that every audience member can enjoy high-quality visuals. With a maximum viewing angle of up to 160°, the screen allows more flexibility in positioning and accommodates a larger number of viewers.
2.5 Slim, Lightweight Design
The ultra-thin design and lightweight, integrated die-cast aluminum structure make indoor LED displays slim, lightweight, and aesthetically pleasing. Their reduced weight lowers the load requirements on installation sites and helps save on labor costs.
2.6 Energy Efficiency
Indoor LED displays use energy-efficient LED pixels, combined with well-designed power-saving circuits and energy-efficient driver ICs and power supplies. This ensures not only lower energy consumption but also stable and reliable operation.
