The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1, an embodiment of the present application provides an array display module, including: the array light source is provided with a light guide part and a light emitting component in sequence on the light emitting side light of the array light source, the array light source comprises a plurality of arrays of light emitting units 1, the light guide part is provided with a plurality of arrays of light channels 2, and the light emitting units 1 and the light channels 2 are correspondingly arranged; the light emitting component comprises a light distribution lens 3 and a diaphragm 4 arranged on the surface of the light distribution lens 3, light beams emitted by the array light source enter the light emitting component after passing through the corresponding light channel 2, and the diaphragm 4 transmits the light beams and blocks ambient light.

The array light source is composed of a plurality of light-emitting units 1, and the plurality of light-emitting units 1 are distributed in an array; similarly, the light guide has a plurality of light channels 2, and the plurality of light channels 2 are distributed in an array. Further, each light channel 2 corresponds to one light emitting unit 1, in other words, the array pattern of the plurality of light channels 2 is identical to the array pattern of the plurality of light emitting units 1.

The light-emitting unit 1 comprises at least one light source, and the light source comprises at least one light-emitting chip, so that the array light source formed by the light-emitting units 1 in multiple arrays emits light more uniformly, and the boundary of the lighting effect of the array is clearer.

Each light-emitting unit 1 is electrically connected with the controller, that is, each light-emitting unit 1 can independently control brightness, color and the like, so that independent control is realized, a plurality of light-emitting units 1 in the array can be freely combined according to different requirements, and the change of light sources is more.

When a plurality of arrays of light emitting units 1 are arrayed, they can be arranged and combined in any way to form an array light source with a larger area, and the specific array mode is not limited.

Further, the material of the lens 3 includes a transparent material or a scattering material. The lens 3 can be made of transparent PC, PMMA and other optical materials with smooth surfaces or patterns on the surfaces.

The light beams emitted by the array light source reach the lens 3 through the collection and transmission of the array light channels 2, and finally the light rays collected in each light channel 2 are emitted through the lens 3, so that an array lighting effect is formed. The lens 3 is used for emitting light beams passing through the array light channel 2, and the diaphragm 4 is used for processing the light beams passing through the lens 3, so that when the array light source is lightened, the array display module can show an array lightening effect; when the array light source is not lighted, the array display module shields the array light source and the array light channel 2 and only displays the light-emitting surface of the light component. Therefore, when the array light source is not lightened, the array display module can not see the array light source and the array light channel 2 from the appearance, so that the phenomenon that the array light source and the array light channel 2 form visual indication marks due to factors such as light reflection and the like is avoided, and misjudgment of indication signals is formed.

It should be noted that, when the array display module is not lighted, the light-emitting unit 1 cannot be observed on the outer surface, and the surface (the light-emitting surface of the light-emitting component) can have the effects of a mirror surface and a frosted mirror surface; the surface color can be different according to different membrane 4 materials, coating processes and optical channel 2 materials; the surface reflectivity is adjusted according to different membrane 4 materials, coating processes and optical channel 2 materials.
