Abstract
A display, a lighting device and a method for manufacturing the lighting device are provided. The lighting device comprises a substrate, an electrode layer, a plurality of light source units and a light scattering layer, which is covered by a transparent layer and a reflector layer to create a uniform surface light within an ultra thin format. A yellow phosphor layer is disposed above the reflector layer to create white light when a blue LED or UV LED is used. The lighting device also provides a unique electrode layout design which can be applied for local dimming control and can be easily applied for large size product applications.
