Problems solved by technology

[0003] However, in the prior art, the light emitted by the light source module needs to be coupled into the optical channel through the microwave guide aligned with the optical channel, wherein the alignment accuracy of the microwave guide and the optical channel will seriously affect the coupling of the light into the optical channel. Optical Channel Efficiency
In other words, the existing display components require extremely high assembly accuracy, which increases the complexity of assembly
In addition, in order to display a full-color image, the existing display components need to use multiple sets of light source modules, and this design also makes the material cost of the existing display components relatively high

Abstract

The invention discloses a display assembly, which comprises a display substrate, an optical waveguide, a grating and a first luminescent assembly. The display substrate is equipped with a plurality of light paths and a light incident side. The light paths parallel to each other together form a plurality of array-configured display picture elements. Each of the light paths is equipped with an inlet at the light incident side of the display substrate. The optical waveguide is arranged at the light incident side of the display substrate. The grating is arranged on the optical waveguide. The first luminescent assembly provides a first ray. The first ray enters into the optical waveguide and then is emitted to the light incident side of the display substrate by the grating. The first ray passing through the grating is diffracted to be a plurality of first set colored lights of different wavelengths emitted along different angles. The first set colored lights comprises lights with a plurality of different wavelengths and the lights with different wavelengths enter into the corresponding light paths to be served as the light source of the display picture elements.

Description

【Technical field】 [0001] The present invention relates to a display component, and in particular to a self-illuminating display component. 【Background technique】 [0002] Existing display components include a display substrate, multiple groups of light source modules and multiple microwave guides. The display substrate has a plurality of optical channels arranged in parallel with each other, and the corresponding optical channels are aligned through each microwave guide, so that the light emitted by the light source module can be coupled into the corresponding optical channels through each microwave guide. In addition, driving electrodes are arranged under the optical channel of the display substrate, and these driving electrodes can change the refractive index of the medium connected with the optical channel. In this way, the total reflection of the light in the light channel will be destroyed, and the light will be emitted from the light emitting surface of the display su...
