Light-emitting module, display module and display device

A display module, comprising a light-emitting module and a display panel on a light-emitting side of the light-emitting module, wherein,

• the light-emitting module comprises a plurality of light-emitting elements, a micro lens array disposed on a light-emitting side of the plurality of light-emitting elements, and a low-refractive material layer disposed on a side of the micro lens array away from the plurality of light-emitting elements, wherein a refractive index of the low-refractive material layer is smaller than a refractive index of the micro lens array;
• and after being processed by the micro lens array and the low-refractive material layer, light emitted by the light-emitting elements forms a dot matrix light source which irradiates a plurality of preset opening regions which are disposed at intervals;
• the display panel comprises a plurality of pixel opening regions and opaque regions disposed between adjacent pixel opening regions;
• and
• the plurality of preset opening regions are disposed in correspondence with the plurality of pixel opening regions.
