    • With multilayer index matching, “Panda black” is defined as lower reflectance, smaller color difference (ΔE between BM and AA), and higher blackness, It’s the best seamless solution.
    • “Panda Black” includes a set of optimization of OGS touch screen, TFT display, OCR optical bonding, and anti-reflection film or surface treatment, etc.

Orient Display: Full Spectrum Reflectivity of BM and AA Area

Both BM and AA area can be lower than 1.7%, and AA area can be lower to 1.45%.

Orient Display: Reflectivity and Delta E of Different Generations OGS

    • Each generation of OGS optical bonding unit, we keep improving the performance of reflectivity and ΔE, in order to achieve the lower reflection and better seamless effect.
    • Now OGS 3.0 “Panda Black” touch and display optical bonding unit with AR surface, not only reflectivity can be lower than 1.7%, but also ΔE can be lower than 1.7 (Both 1.7).

 

2. “Panda Black” Cluster Lens – The Best Seamless Solution

W/O AR W/ AR

While “Panda Black” cluster lens optical bonding with TFT display, seamless black across the display area and cover lens border, show the best decorative effect and elegant looks.

    • New technology instead of ink printing;
    • Seamless black between VA and BM:

△E<1 without AR film

△E<2 with AR film

    • Surface AGAR treatment is optional;
    • Size: Max 3rd generation(550*650mm).

3. “Pilatus” Automotive Touch Screen – Bridge and ITO Invisible Technology

Features:

    • No Bridge design, no any bridge reflection under strong light;
    • New index matching design, no any ITO gaps reflection under strong light;
    • More durable on sunlight simulation, DIN75220;
    • Smoother and more reliable connection between internal ITO;

    • Under strong sunlight, Bridge cause some reflection issue, and ITO gaps is obviously also. “Pilatus” automotive touch screen is designed to reduce this reflection;
    • The new index matching design reduce the reflectance difference between ITO pattern and gaps;
    • Without bridge design, there is no bridge shining issue even under strong light.
