    P4.81 LED Display

    Indoor Rental LED Display
    • Light weight
    • Good Heat Dissipation
    • Low Power Consumption
    • Convenient Installation
    • Easy Move


    The P4.81 indoor SMD full-color display is a modified high-refresh product. The product is not only more affordable but also significantly more effective.
    Adjust the color balance of low gray balance: The driver chip has a correct color shift, eliminating the color shift in the case of pre-charging.
    Reducing low gray unevenness: The module achieves uniform brightness, high consistency of the driving chip, uniform brightness of pixels, and more uniform and clearer picture display.
