    LED LAMPS SOLUTION

    There are plenty of LED brands on the LED
    display market. When choosing the LED lamp
    brands few parameters are very important to
    take into account if we want to achieve a
    Virtual Production or XR studio LED screen
    standard

    This particular parameter counts for more than 30% of the total price of the LED screen so it’s capital to consult a specialist that can best advise you. We recommend

    • working with a brand that is specialist and have experience working with small LED pixel
    • Using black encapsulation to increase contrast ratio
    • If possible use protective coating, as it could be very beneficial if your studio will be itinerant base means assembled and dis-assembled frequently in multiple locations. LTP, AOB, COB, GOB. Water-proof, Dust-proof, Anti-collision, Repairable
    • If possible use golden wire as it would reduce failure rate of the LED pixel by 50% (But it will also triple the price x3)
    • Use black encapsulation or black face series to increase contrast ratio
    • Wide color gamut LED brand and series

    what is Color Gamut?

    The color gamut describes a range of color within the spectrum of colors that are identifiable by the human eye (visible color spectrum). Since most displays are limited in the colors that they can produce, each device will also follow one or more color standards that define its specific color gamut. First we must understand how color gamut is depicted on a technical level. Presented as a triangle on an XYZ axis, the Y refers to the maximum color luminance possible within the gamut, while the X and Z points indicate the complete range of chromaticities — a color’s hue and colorfulness. When all is said and done, the final result perfectly reflects a color gamut’s range of capabilities

    Which frameworks set the standard for color production?

    The answer lies in color standards, which relate directly to standardized color gamuts. With that in mind, common color standards include:

    Rec 709
    DCI-P3
    REC 2020
    REC 709
    Adobe RGB
    CG-3184k
    NTSC

    Color gamut is directly linked to the chosen LED lamp series you get so before buying the LED lamps, make sure to create a sample and test it to ensure it can reach the color gamut standard required.

    Here is an example of the Color gamut coming from Nationstar NH series that can reach 93% of the DCI-P3.

    What is HDR?
    HDR

    HDR stands for High Dynamic Range and refers to the contrast (or the difference) between the brightest and darkest parts of an image.

    The idea is that your eyes can perceive whites that are brighter and blacks that are darker than traditional SDR TVs had been able to display. HDR content preserves details in the darkest and brightest areas of a picture, details that are often lost using old imaging standards such as Rec.709.

    HDR10 is the standardized version of format that TVs and content are required to support.

    The pursuit of High Dynamic Range (HDR) is the dream of getting closer to the Human Visual System (HVS) in all that we experience as viewers.

    • HDR is a new display system that is designed to better represent what the human vision system (HVS) can see.
    • Human vision sees the world with lots of dynamic range and a wide range of colors.
    • Modern cameras have up to 14 stops of dynamic range.
    • BT.709 Standard Dynamic Range (SDR) systems can show only up to the equivalent of about 6 stops.
    • HDR attempts to show much more of the world we see, starting with the larger camera dynamic range available today at source and through the production chain and ultimately for presentation on affordable displays optimized for HDR.

    What does HDR
    bring?

    HDR technology increases the dynamic range of display image quality by nearly 5 times and the gray scale by 4 times to 10-bits. The color is fuller, the image quality is more exquisite, and the image is more realistic.

    Compared with SDR

    Compared with SDR 1080P technology, HDR has a larger image resolution: UHD 4K; Wider color gamut: BT2020, the same picture can present more color information and more details

    What can HDR do for you ?

    Increased contrast and Luminance ranges
    Expanded range between darkest and lightest parts of image allows for a greater level of contrast.
    Subtle shading
    Subtle shading makes the scene look more detailed and realistic.
    Broadened color spectrum
    Wider and finer color spectrum allows for smoother color gradation.
    HDR High Dynamic Rang
    Expanded range between darkest and lightest parts of image allows for a greater level of contrast.

    A wider and finer color spectrum allows for smoother color gradation

    Image comes closer to what the human eye can see, allowing the picture to pull the viewers into the scene

    Subtle shading makes the scene look more detailed and realistic.

    Achieving HDR / What makes HDR
    1. 709
    2. 2020
    Wider and richer color spectrum contribute to a more vivid and detailed HDR image.
    Realizing HDR
    ≥1000nits LED // ≤400nits LCD High brightness: LED display

    HDR requires a display with high brightness. LED displays can easily achieve this, while standard LCD and other types of display can only reach 400nits.
