¶ 1. Background
Nowadays, an increasing number of LED display projects are equipped with 3D functionality as a standard feature. Over the recent years, the number of 3D projects in various regions has grown substantially, presenting a significant challenge for the front-end team in terms of setting up the 3D solution and being mindful of certain considerations. In response to this challenge, the COEX-3D solution document is to assist users in efficiently completing system design, on-site debugging, and problem diagnosis for their 3D projects.
¶ 2. How 3D Technology Works
3D imaging is created by the visual depth perceived by our eyes. The distance between the pupils of human eyes is typically around 8cm. When we look at objects, our eyes perceive depth differences, which allows our brain to form 3D images. In order to create the illusion of 3D images for people, it is necessary to present different images to the left and right eyes. This creates a depth gap between the two images, replicating the way our eyes naturally perceive depth. This is how the sensation of 3D stereoscopic vision is achieved.
The COEX series products adopt active shutter 3D technology to be 3D ready. This is achieved by increasing the refresh rate of the screen, splitting the image into two distinct halves for the left and right eyes. These two sets of images are displayed in rapid succession, alternating seamlessly. In tandem, a 3D emitter synchronizes with the 3D glasses via a precise timing signal. This signal ensures that the glasses alternate between blocking each eye, permitting each to view their corresponding images precisely when intended. This process creates stereoscopic 3D images.

¶ 3.2 System Topology
Input the 3D video source into the LED display controller, and then output it to the receiving card, which displays the content on the LED screen. The EMT200 transmits 3D signals, while the 3D glasses detect and receive these signals. By observing the LED screen displaying the 3D video source through the 3D glasses, you can experience the 3D visual effect.
There are two possible connections for the EMT200 within the entire system:
- Connection option 1: The EMT200 is connected behind any receiving card.
- Connection option 2: The EMT200 is connected between the controller and the receiving card.

¶ 8. Input Source Requirements and Parameter Settings for 3D
The COEX series products all share the same settings for 3D. This chapter will take the MX40 Pro as an example. The MX40 Pro comes with three types of input source interfaces: HDMI, DP, and SDI. The requirements and parameter settings for the input sources to enable the 3D function are the same across the different types of input source interfaces.
MX40 Pro - Rear Panel
¶ 8.1 Send-Only Controller Mode
This chapter provides an example of using the MX40 Pro in Send-Only Controller mode to enable 3D via the HDMI input interface. There are a total of 9 different setup types that you can refer to, depending on your specific needs.
| No. of Controllers | Example Description |
|
1 unit |
The video source is in side-by-side, top-and-bottom, or frame sequential format. |
|
2 units |
|
¶ Video Source Format
The video source must contain the images intended for both eyes.
- If the video source is in side-by-side format, the width of the video source resolution must be twice that of the LED screen size.
- If the video source is in top-and-bottom format, the height of the video source resolution must be twice that of the LED screen size.
- If the video source is in frame sequential format, the video source resolution must be the same as the LED screen size.
¶ LED Display Controller 3D Parameters
You can configure the 3D parameters via VMP.
- Source format: Choose the source format based on the video source.
- Right eye offset: This indicates the offset of the right eye image. When the source format is side-by-side, provide the value for x offset. If the source format is top-and-bottom, provide the value for y offset. Please note that this option is grayed out when the source format is frame sequential.
- Eye priority: This option is determined by the timing signal received by the 3D emitter EMT200 for the first time. It should be configured according to the actual effects in the field and does not need to be altered once set.
- 3rd party emitter: Only toggle on this option when using a third-party emitter.
- Note: If you use a third-party emitter, you will still need to connect it to the EMT200. Refer to 3.2 System Topology for instructions on how to connect the EMT200. The third-party emitter should be connected to the 3D signal output port of the EMT200.
- Emitter delay: Usually, the default delay time should be sufficient. However, you can fine-tune its value if the 3D effect doesn't meet the expectations.

¶ 8.2.2 Example 2: 2 Units of MX40 Pro (in All-in-One Controller Mode) to Achieve 3D Readiness
There are two ways to achieve 3D readiness with 2 units of MX40 Pro in All-in-One Controller mode:
- Method 1: The left and right, or top and bottom images of the 3D video sources in side-by-side or top-and-bottom format are processed and combined based on the loading ratio of each MX40 Pro using a video processor or splicer. For 3D video sources in frame sequential format, they can also be processed according to the loading ratio and then routed to the corresponding MX40 Pro. The settings needed to achieve 3D readiness are the same as those of using a single MX40 Pro.
- Method 2: Feed the 3D video source to HDMI 1 and HDMI 2 of each MX40 Pro using a splitter or other distributors to ensure that each MX40 Pro receives the same synchronized 3D video source. Next, use VMP's cropping and scaling function to achieve screen splicing with two units of MX40 Pro. The settings needed to achieve 3D readiness are the same as those of using a single MX40 Pro.
¶ Method 1: Use a Video Processor or Splicer
¶ Video Source in Side-by-Side Format, with Two Units of MX40 Pro Spliced Side by Side
Use two units of MX40 Pro, each loading a screen at a resolution of 3840×1080, and splice them side by side to create a single screen with a resolution of 7680×1080.
Set up the video processor or splicer to crop and splice the 3D source. The goal is to splice the image after cropping, effectively dividing a 15360×1080 image into four parts and then combining them based on the controller position (splicing order detailed below). The end result should yield two 3D sources containing respective halves of the left-eye and right-eye images for the intended controller. The source should have a minimum resolution of 800×600 and a maximum resolution of 8192×1080.
Feed the 3D sources to the two controllers through the HDMI interfaces. Each MX40 Pro is responsible for loading its corresponding 3D content.
