• The project budget is limited, in which case you may want to consider options with a slightly larger pixel pitch.

What Advantages Does the P1.538 LED Module Offer?

High-Density Pixels for Detailed Image Display

This module achieves a pixel density of 422,500 pixels per square meter, resulting in exceptionally rich image detail. 

For example, when displaying the same content on a 1-square-meter screen, a 4-megapixel panel will provide more detail and better image quality than a 2-megapixel panel. The image will also appear smooth and free of graininess, even when viewed up close.

Capture High-Refresh-Rate Images Without Scan Lines

If the refresh rate of your installed screen is too low and the screen is intended for filming, such as an LED screen in a studio or at a product launch event, scan lines may appear in the camera footage. This not only affects the viewer’s experience but may also damage your brand’s reputation.

When purchasing this P1.538 LED module from JYLED, you can choose a screen with a refresh rate of 3,840 Hz or even 7,680 Hz. High-refresh-rate LED panels ensure a clear and smooth image when captured by a camera.

Wide Viewing Angles Support Large-Scale Content Displays

Standard P1.538 LED modules offer a viewing angle of 160° both vertically and horizontally, while modules using COB packaging technology can achieve a viewing angle of up to 170°.

The wide viewing angle is ideal for large-scale displays because it ensures that viewers seated on either side of a long, narrow screen can see the content clearly and without color distortion.

Adjustable Brightness Balances Clarity and Viewing Comfort

The modules support 100 levels of brightness adjustment, from 0 to 100. If your indoor environment has bright ambient lighting, you can increase the screen brightness to ensure image visibility. 

If your indoor environment is dimly lit, you can lower the screen brightness appropriately to provide viewers with a softer, more comfortable viewing experience while maintaining content clarity.

Seamless Tiling in Multiple Sizes

The P1.538 LED module has a standard size of 320 × 160 mm, and the modules can be assembled into 640 × 480 mm LED cabinets.

By installing different numbers of LED cabinets horizontally and vertically, you can create screens with various aspect ratios. For example, screen aspect ratios such as 21:9, 16:9, and 4:3 can all be easily achieved.

What Is the Optimal Viewing Distance for the P1.538 LED Module?

According to LED display industry standards, the appropriate viewing distance is influenced by the pixel pitch. However, in practical applications, the optimal viewing distance for LED panels is also affected by ambient lighting, viewer comfort, and the content being displayed.

We will analyze the optimal viewing distance for P1.538 indoor LED modules from several perspectives:

• Minimum Viewing Distance: When viewing content displayed on the modules, you should stand at least 1.5 meters away to ensure that the image appears smooth, detailed, and free of graininess.
• Comfortable Viewing Distance: The optimal viewing distance for a screen is 1 to 2 times the numerical value of the pixel pitch in meters. Therefore, the optimal viewing distance for a P1.538 LED module is 1.54 to 3.08 meters.
• Different Viewing Distance Requirements for Videos, Small Text, and Data Charts: When playing videos, a viewing distance slightly beyond the optimal range typically still provides a good viewing experience. However, when displaying content such as small text or data charts, it is best to stay within the optimal viewing distance whenever possible.
• How to Select Pixel Pitch Based on the Minimum Viewing Distance: Generally, when the minimum viewing distance is measured in millimeters, a suitable pixel pitch falls within the range of the minimum viewing distance divided by 2,000 to the minimum viewing distance divided by 1,000.

In addition to P1.538, P1.667 and P1.86 are also suitable small-pitch modules for indoor use. So, which of these three modules is best suited to your project? Let’s look at the comparison table below:

Can P1.538 LED Modules Be Used to Build 1080p and 4K Screens?

We typically use six 320 × 160 mm P1.538 LED modules to assemble a single 640 × 480 mm LED cabinet and then combine multiple LED cabinets to achieve the desired screen size. Therefore, it is entirely feasible to use P1.538 LED modules to build a 1080p or 4K screen.

How Much Does It Cost to Install a 1080p Screen Using P1.538 LED Modules?

1080p = 1,920 × 1,080 pixels, while a single LED cabinet has 416 × 312 pixels.

This means that the number of LED cabinets required horizontally is 1,920 ÷ 416 = 4.62 ≈ 5.

The number of LED cabinets required vertically is 1,080 ÷ 312 = 3.46 ≈ 4.

Installing a 1080p screen requires 4 × 5 = 20 P1.538 LED cabinets, with a total screen area of 640 × 480 mm × 20 = 6.144 m².

Therefore, the cost of installing a 1080p screen using P1.538 LED modules, based on the lowest price, is 6.144 × 1,265 = $7,772.16.

How Much Does It Cost to Install a 4K Screen Using P1.538 LED Modules?

4K = 3,840 × 2,160 pixels. The number of LED cabinets required horizontally is 3,840 ÷ 416 = 9.23 ≈ 10.

The number of LED cabinets required vertically is 2,160 ÷ 312 = 6.92 ≈ 7.

Installing a 4K screen requires 10 × 7 = 70 LED cabinets, and the total screen area is 640 × 480 mm × 70 = 21.504 m².

Therefore, the cost of installing a 4K screen using P1.538 LED modules, based on the lowest price, is 21.504 × 1,265 = $27,202.56.

Note: The screen procurement costs above include only the LED modules and do not include controllers, power supplies, cables, structural supports, or other accessories.

What Factors Should Be Considered When Purchasing and Installing P1.538 LED Modules?

If you are considering purchasing P1.538 LED modules to install an indoor display, you should consider the following issues:

Therefore, for a single project, we generally recommend purchasing all LED modules at once to ensure a high level of color consistency.
• Select an Installation and Maintenance Method: Please provide us with details about your installation environment and display requirements so that JYLED’s engineers can help you choose the most suitable installation method for your specific circumstances, such as wall-mounted, floor-standing, or suspended installation. The right installation method not only delivers optimal display results but also helps you save on installation costs.
• Screen Aspect Ratio: Different screen aspect ratios are suited to different types of content and offer different viewing experiences. For example, a 21:9 screen is suitable for creating an immersive background display in a theater, while a 16:9 screen is ideal for showing movies. Therefore, you should select the appropriate screen aspect ratio based on your specific needs.
• Number and Brand of Power Supplies: Based on the power supply’s load capacity and the modules’ power consumption specifications, a single LED cabinet typically requires 1 to 2 power supplies. Choosing a high-quality power supply brand, such as Mean Well, ensures more stable screen operation.
• Number of Receiver Cards and Load Capacity: Purchasing receiver cards that are compatible with your project ensures stable signal transmission and helps reduce unnecessary costs. If you prefer not to calculate the load capacity yourself, you can choose the receiver card procurement solution provided by JYLED.
• Selection of Video Processors: If you have a sufficient budget and prioritize load capacity and quality, you can choose NovaStar LED video processors. If you are more concerned about cost-effectiveness, Colorlight video processors are a good option.

Other Installation Precautions

• When installing LED panels, workers should take care not to bump or damage them.
• LED panels can be adjusted slightly during installation to ensure screen uniformity and flatness.
