What is XR LED screen?

XR virtual shooting is showing new growth. In the first quarter, with the blessing of various large-scale programs such as the Winter Olympics, Spring Festival Gala, and New Year’s Eve Gala, XR technology has been out of the circle many times, attracting the attention of the public.

XR virtual shooting first originated from film shooting. The combination of LED screen and XR technology allows actors to perform in the space constructed by the screen, replacing the conventional green screen, so as to reduce the use of green screen during shooting and reduce shooting costs.

Compared with traditional green screen technology, XR technology can significantly reduce the cost of special effects. The data shows that the cost of special effects mainly includes labor cost (accounting for more than 60%), software cost (accounting for 10%-20%) and hardware cost (accounting for 20%-30%). The application of XR technology saves the cost of software rendering and special effects labor costs in the later stage, which is expected to account for 25%.

At this stage, XR virtual shooting can be specifically applied to live broadcasts, new product launches, content scenarios, reality shows, variety shows, car commentary and other scenarios, bringing immersive experience, multi-scene applications and a high-tech atmosphere.

As an advanced form of virtual production, LED displays have greatly improved immersion and interactivity. But at the same time, higher requirements are also placed on technical capabilities, and such requirements are slightly different in different scenarios. For example, in film production, there are high reliability standards, and in live broadcast scenarios, low latency is immersive. Base.

No matter what kind of scene, the components of XR virtual shooting have higher requirements than ordinary devices. Recently, Jingtai Optoelectronics took its TOP-level products 1212 and 1415 as examples, compared with ordinary light source devices, and obtained the following key points.

high contrast

In a specific shooting scene, to ensure that the LED screen is more realistic under the lens, then this requires the LED display to have high contrast and high brightness.

It is reported that Jingtai products are blessed with “black technology”, and the contrast ratio has increased by 30%. This contrast enhancement mainly relies on colloidal atomization + extreme matte black processing technology to improve contrast. Reduce the color cast caused by the return temperature difference and reduce the problem of surface contamination and reflection, and improve the consistency of ink color.

High brightness + low power consumption

In order to be authentic, in addition to high contrast, high brightness is also a major requirement. Compared with traditional curtains, LED display backgrounds are prone to reflection effects, and high brightness and high contrast can make reflections difficult to detect.

It is reported that Jingtai products prefer wavelength and brightness centralized chip solutions, Kabi subdivision, uniform mixing of materials, and normal distribution graphic monitoring. And the power consumption is reduced, P1.9/18 scan, the brightness can reach up to 1800nit or more.

It is worth noting that although there are no special requirements for power consumption in current scene applications, because XR shooting is mostly performed indoors, low power consumption is also one of the requirements worthy of attention.

super vision

Different from the conventional large screen, the XR virtual scene needs to cooperate with the multi-angle camera to complete the multi-scene effect of the film or other film and television production, so this requires the LED display to have a wider field of view in practical applications.

Jingtai Optoelectronics adopts the large viewing angle design of lamp beads, the in-line structure design of the functional area, and the in-line RGB soldering method, which shortens the chip margin, keeps it away from the cup wall, expands the display viewing angle, and reduces the problem of reddishness between groups of different viewing angles. Enhanced 3-in-1 color mixing effect.

display effect

In general, the light source devices used for XR photography are more demanding. Especially in film shooting, due to the high requirements of film level and even automotive level reliability standards, in actual use, it is also necessary to ensure the corresponding display effect and create an immersive atmosphere.

It is reported that Jingtai Optoelectronics uses low-speed molds to facilitate the injection of plastic into the mold cavity, ensuring smooth demoulding, full plasticity and high consistency, improving pin flatness, reducing the problem of yin and yang sides of the hanging screen caused by SMT patches due to oversize problems, and improving the display.
