Please read this article carefully if you are planning to purchase LED screens for virtual production (XR extended reality technology) or are building a virtual production/virtual entertainment studio. This article will help you understand what you need to focus on if you are tensed about selecting the wrong LED screen.
Brightness
At the moment, the XR led display for Virtual Production that is frequently utilized for virtual shooting has a brightness of between 1000 and 1500 nits. The LED screen’s peak brightness should not fall below 1000Nits after the calibration and picture quality engine have begun. The self-lighting characteristics of the LED screen cannot be played effectively if the brightness is lower than this, but the light effect of the virtual environment can be accurately restored.
Scan
Scan is the ratio between the total number of screen module rows and the number of rows that the LED screen drives at any given time. For instance, the P10 modules have 16 LED lines, four of which are lit simultaneously; consequently, the number of scans displayed on this screen is 4/16, or 1/4 scan.
The performance of the screen improves with a larger denominator, and the likelihood of horizontal and black lines while filming decreases as well. As a result, scan sizes should not exceed 1/16 scan.
Viewing Angle
The LED screen’s viewing angle must be at least 140 degrees in both the horizontal and vertical directions. For a better display effect, it’s better to have it above 160 degrees. The more expansive the viewing angle, the more leeway there is for the camera to move around during virtual shooting and the fewer restrictions there are on creative concepts.
Gray Scaling
The process of converting an image from one color space to another, such as RGB, CMYK, HSV, and so on, is known as gray scaling. to gray tones, from the darkest to the lightest. We must select a screen with at least 14 to 22 bits of gray-scale display capability for virtual photography.
Color Gamut
For LED screen color restoration, color gamut virtual shooting is a very strict requirement. The Rec.2020 gamut’s color requirements should be met as much as possible by the LED screen.
Mechanical Structure
LED screens need to be easy to put in and take out, and they need to have a flat surface with no obvious gaps. In addition, it is best to provide multiple connection angles for the screen, particularly for corner protection.
Additionally, the LED power supply must have dependable cables and a good heat dissipation design in order to avoid black screens while filming.

Moire Effect
Select a screen with reflective processing to prevent reflected light from affecting the shooting effect on the LED screen when shooting. Additionally, mole lines, or irregular water ripple patterns, will appear in the image when the camera is used to capture the LED screen image if the sensor pixel’s spatial frequency is close to that of the stripes. Special surface processes that significantly reduce the moorgrain effect are already present in some LED screens.
High Refresh Rate
The screen’s high refresh rate prevents moiré and other reflected light spots from appearing on the surface.
Super Brightness Adjustment
Improve performance by adapting to the brightness of various virtual studio environments.
Any signal can be monitored in real time and switched synchronously with low latency. Ultra-low latency ensures that playback content is displayed synchronously. The rapid switching of virtual scenes in the virtual studio necessitates on-site real-time monitoring of the screen’s operation, real-time remote control of the display’s content, prompt feedback on issues, and solution suggestions.
To guarantee regular shooting. In order to adapt to various virtual scenes and numerous signal sources, it is also necessary to ensure that any signal is switched synchronously.
Control System for LEDs
The LED control system is crucial. It is in charge of processing the LED screen’s picture quality and display effect, making sure the content being shot doesn’t have flaws like horizontal lines and scan lines, and meeting HDR, ascending and descending, multi-position, green insertion, and advanced real-time LED color mixing needs. The LED control system requires prompt and dependable after-sales support.
Conclusion
Lastly, prior to factory parameter debugging, we ought to pay attention to the LED screen after purchasing it. Before shipment, it is recommended to adjust the effect to meet the requirements of on-site shooting; otherwise, the parameters may not be adjusted to the factory’s specifications, necessitating numerous time-consuming and laborious adjustments to the scene.
