Abstract
A display module comprises: a display panel comprising a substrate, a plurality of light sources including a plurality of light emitting devices mounted on the substrate, a color conversion layer and a color filter layer stacked on each of the plurality of light emitting devices, the plurality of light sources may each be provided with encapsulation structure, and a size of the color conversion layer may be less than a size of the light emitting device.
Claims19
A display module comprising:
- a display panel comprising a substrate;
- a light source mounted on the substrate, the light source comprising:
- a light emitting device;
- a color conversion layer and a color filter layer stacked on the light emitting device, wherein the color filter layer is arranged above the color conversion layer;
- and
- a thin film encapsulation structure which continuously covers at least a part of a side surface of the color conversion layer and the color filter layer, wherein the encapsulation structure comprises:
- a first inorganic film covering an upper surface of the light emitting device;
- and
- a second inorganic film covering from an upper surface of the color filter layer to a side surface of the light emitting device;
- a driving circuit configured to generate a driving signal for the light emitting device;
- and
- wherein an area of the color conversion layer overlaps at least a part of the light emitting device.
