Problems solved by technology

In the prior art, there are generally three schemes for the colorization of Micro-LED silicon-based microdisplays: 1. 3D nanorod technology realizes colorization. This technology can produce RGB three-color LEDs on the same substrate at the same time. is in the research phase;
[0003] 2. Chips of RGB three colors are bonded to the silicon backplane layer by layer through Flip chip or wafer bonding, and then LED graphics are performed after bonding. This technology is relatively complicated and is still in the research stage;
[0004] 3. Colorization by quantum dot printing (QD, QuantumDots, QD is a spherical semiconductor particle with

Abstract

The invention discloses a color film with an ultra-high light conversion rate, a display panel and a preparation method. The color film comprises a transparent substrate and a plurality of concave parts formed in the transparent substrate; a first high-transmittance and high-reflectivity film, a packaging film, transparent convex points and a second high-transmittance and high-reflectivity film are sequentially arranged on the concave parts; the first high-transmittance and high-reflectivity film has high-transmittance to red light and green light and has high-reflectivity to blue light; the second high-transmittance and high-reflectivity film has high-transmittance to blue light and has high-reflectivity to red light and green light; and a light-transmitting window is reserved in part ofthe first high-transmittance and high-reflectivity film. According to the of the invention, the two high-transmittance and high-reflectivity films with different characteristics are adopted, blue light which is not converted completely can be gathered under the action of concave reflecting lenses and returns to quantum dots to continue to participate in conversion, and therefore, light conversionefficiency is improved.
