  • Pitch(mm) :1.2/1.5
  • Applications :
    HD curved display screen setups
    Immersive display solutions
    Curved splicing

Product Features

  • Ebony s 弯
    Bendable and highly flexible

    The single module has a large bending radius, with a bending angle of 11° left and right (the maximum bending radius is 158°), which is suitable for curved and special-shaped scenes and meets the needs of various curved screens.

    Flip Chip COB

    Ebony series are supported by flip - chip COB, ensuring lower power dissipation and more stable qualities.

    Extraordinary Versatility

    1. Magnetic module allows fully front maintenance．
    2. Front installation is available due to the reserved screw hole.
    3. Ultra thin and light-weight cabinet match up with more application scenarios.
    4. Aiming to protect the operator from cut and improve the appearance, the Ebony panel is processed with edge-rounding and electrophoresis.

    Soft COB for Options

    We have multitudinous solution of COB family. Soft COB module helps us to achieve more shapes of the display like concave, convex, multi-shape connection, etc. And the key point is we could use them all with the same COB stuff to avoid the discrepancy of visual sense.

  • Ebony s01
    High Brightness for Options

    1.The larger chip was utilized in Ebony.
    2.There is a layer of film on the surface of COB, which is removed with new process. But it still can be assured the fidelity to original color.

※1：Compared to other flip-chip displays, COB flip-chips have a smaller pad bonding area, creating more space between chips and improving contrast.
※2：Due to the smaller chip size of COB flip-chips, pixel pitches can reach 0.4 to 1.2 mm, enabling finer image quality.
※3： Due to their different basic structure, COB (flip-chip) displays have a relatively wide viewing angle.
※4： Due to their smaller bonding area, COB displays can use larger chips than SMD displays, achieving higher brightness.
※5： COB displays have the voltage required for RGB, while the flip-chip structure reduces current consumption, making them more energy-efficient.
※6：Due to their simple structure, there are fewer process steps leading to defects, resulting in a longer lifespan.
※7：The flip-chip structure has excellent thermal conductivity and low heat generation, dissipating heat directly to the front and back of the PCB, providing excellent heat dissipation.
※8：Due to their different basic structure, COB (flip-chip) displays have fewer production steps and a lower failure rate.
