How to Design the Aspect Ratio and Size of Full-Color LED Displays for Banquet Halls

In banquet hall scenarios, the aspect ratio design of LED displays must balance visual aesthetics and functional requirements. The 16:9 golden ratio is recommended as a reference, which is compatible with high-definition video sources (such as movies and gala live broadcasts) and suitable for wide-screen banquet halls. Common sizes include 8m×4.5m and 10m×5.625m, which can seamlessly connect to 1080P/4K signals. The traditional 4:3 ratio is applicable to scenarios such as PPT presentations and group photo backdrops, and is commonly used in small and medium-sized banquet halls, with typical sizes like 6m×4.5m and 4m×3m. If the banquet hall has a curved stage or irregular walls, curved screens (e.g., 180° inner curve) or circular screens (360° surround) can be designed. It is necessary to confirm the module's flexibility adaptation capability with the manufacturer in advance.

Matching Viewing Distance and Pixel Pitch

The distance between the front-row audience and the screen in a banquet hall is usually ≥3m. It is recommended to choose a pixel pitch of P2.5-P4 (for example, the optimal viewing distance for a P3 screen is 3-15m) to avoid pixel graininess caused by an excessively large pixel pitch. If close-range high-definition display is required (such as the main stage screen), small-pitch screens with P1.8-P2.0 can be selected, but the cost will increase by 20%-30%.

Clarifying Usage Scenarios and Core Requirements

• Wedding banquet halls: High color reproduction (RGB color gamut ≥110% NTSC) is required to support the switching between dynamic video backgrounds and newlyweds' photos. The 16:9 ratio is recommended.
• Business meeting halls: Focus on text and PPT display. The 4:3 ratio can be selected, paired with a split-screen display function (main screen + auxiliary screens on both sides).
• Performance banquet halls: High refresh rate (≥3840Hz) is required to adapt to dynamic scenarios such as dances and light shows. Seamlessly spliced irregular-shaped screens are recommended.

The recommended brightness for indoor banquet hall displays is 800-1200cd/㎡, and direct exposure to strong light on the screen should be avoided. If there is a demand for light shows, the manufacturer should be informed in advance to conduct anti-reflection treatment (such as a matte mask).

Installation Method Selection

• Wall-mounted type: Suitable for scenarios where the wall load-bearing capacity is ≥50kg/㎡. Steel structure brackets need to be pre-embedded, and the distance between the screen and the wall should be ≥10cm for heat dissipation.
• Ceiling-mounted type: The screen is suspended from the ceiling via chains, suitable for banquet halls with a floor height of ≥5m. It is necessary to ensure the safety of the load-bearing structure (the manufacturer should provide a mechanical calculation report).
• Floor-mounted type: Directly fixed on the stage floor. Waterproof and moisture-proof treatment should be carried out (such as raising the bottom by 5cm) to avoid module damage caused by spilled drinks.

  

Wiring Specifications

Signal cables (HDMI/DP) should be routed separately from power cables to avoid electromagnetic interference. For long-distance transmission (>30m), optical fiber transmission must be adopted to ensure no signal attenuation.

Through the design of the above dimensions, the visual effect of the LED screen in the banquet hall can be ensured, while balancing cost and durability.
