  • Publication number: 20250089415
    Abstract: The invention discloses a display module comprising a black optical layer and a transparent protective layer. The black optical layer covers the light-emitting units and ensures proper alignment and sealing. Light-emitting units penetrate the optical layers to maintain uninterrupted light output. The packaging structure reduces moisture intrusion and protects against environmental damage. A transparent protective layer overlays the black optical layer, enhancing durability and structural integrity. Additionally, the module incorporates an anti-glare film press-fitted onto the packaging layer, minimizing external light interference and optimizing light distribution across viewing angles. These design features enable a thinner display with consistent optical performance.
