- Words like “include” or “include” mean that the elements or items appearing before “including” or “including” cover the elements or items listed after “including” or “including” and their equivalents, and do not exclude other component or object.
- Words like “connected” or “connected” are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. “Up”, “Down”, “Left”, “Right”, etc. are only used to indicate the relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
- the light-emitting side of the display substrate 20 is further provided with an accommodating structure layer 32 , the accommodating structure layer 32 has a plurality of accommodating grooves, the accommodating grooves correspond to the light-emitting devices 23 one-to-one, and the light-emitting portion 31 is disposed in the accommodating grooves.
- the accommodating structure layer 32 may be made of a photosensitive material, so as to facilitate manufacture.
- the accommodating structure layer 32 can be made of a material with high reflectivity, so as to improve the utilization rate of light.
- the surface of the light emitting portion 31 away from the display substrate 20 is a convex surface.
- the convex surface means that the surface protrudes toward the outside of the light emitting portion 31 , so that the light emitting portion 31 forms a convex lens structure.
- the difference in brightness at each viewing angle is small; after the light from the test light source passes through the convex lens, the brightness at the forward viewing angle (ie, the position with a smaller viewing angle) increases .
- the brightness at the front viewing angle of the display panel can also be increased.
- the black matrix BM, the color filter layer, the accommodating structure layer 32 and the light emitting portion 31 can be formed on the second substrate 21 to obtain a cell-matching substrate;
- a filling layer 35 is formed on the assembling substrate 20 or on the assembling substrate, and the display substrate 20 and the assembling substrate are arranged in a assembling process to form a display panel.
- FIGS. 16A to 16C are schematic process diagrams of step S20 provided in other embodiments of the present disclosure. As shown in FIGS. 16A to 16C , step S20 includes:
