xR solution for LED display

xR SYSTEM solution

xR has revolutionized the audiovisual industry, this technology is present in the creation of all types of content creation. It has become ubiquitous in film creation and is changing the process forever. xR is meaning: AR+VR+MR = virtual implantation + virtual scene + real subject +real scene.

xR is based on MR green screen shooting, which realizes real-time rendering of large-screen content and real-time shooting of biological subjects. It is widely used in many fields such as film and television production, radio and television program production, product launch, advertising shooting, cultural tourism promotion, MV production and so on. The actual system includes camera, lens tracking system, simulation scene rendering system, LED screen, screen management system, centralized control system, synchronous clock system, and synthesis system.

Requirements of xR solution for LED Display and its control system

Adequate visual refresh rate on display --no shooting lines on camera

display design led screen

  • Low scan, best display effect
  • Less than 8 scans recommended

control system

  • Adequate refresh rate in low grayscale ensured in collaboration with ic
  • Genlock available to keep video source, display, cameras

shooting lines

Improve the refresh of each gray scale can effectively solve the shooting lines issue.

Reduce the number of scans while designing the display. It is recommended that the number of scans not exceed 16 scans for shooting applications.

Prioritize the reduction of current to reduce brightness, and preset multiple brightness adjustment modes that prioritize the use of current.

Driver IC mode adjustment.

Random scanning.

Rolling black lines


Frame tracking technology to reduce black field waiting time.

Genlock function of the controller to synchronize the LED display with the camera, and fine-tune the phase of Genlock​

From the relationship between camera exposure time and LED display frame rate, we can determine the proper combination of shutter angle and frame rate for the most optimal shooting result.

We can support frame multiplication, allowing for expansion of frame rate.

precise color

Adequate grayscale on display — colors more precisely controlled

Display design

  1. Customized color gamut covered by the RGB lamp beads
  2. Displays uncoupled designed(screen design and IC selection)
  • White to black coupling
  • Black to white coupling
  • Cross-board coupling

Control system:

Increase in display grayscale ensured in collaboration with IC

Capability of calibrating the screen

2.1 The brightness calibration of the screen from 0 to 255 conforms to the EOTF curve;

2.2 Calibrate the color accuracy of the screen to ensure δe<4

1. Accurately capture the original color gamut of

the display.

2. Automatic adjustment according to the color

gamut requirements of the input source.
