Color film substrate, method for preparing color film substrate, and display panel

A display panel, which comprises a color film substrate and a light-emitting unit, wherein the color film substrate comprises:

• a substrate;
• a light shielding layer, wherein the light shielding layer is arranged on one side of the substrate, and the light shielding layer is provided with a plurality of openings, and each opening exposes a part of the substrate;
• and
• a plurality of pixel units disposed in the plurality of openings of the light shielding layer, wherein each of the pixel unit comprises a first color sub-pixel unit, a second color sub-pixel unit and a third color sub-pixel unit respectively located in different openings of the plurality of openings;
• wherein one condensing component and the first color sub-pixel unit are arranged in one of the plurality of openings of the light shielding layer, and the one condensing component is disposed between the first color sub-pixel unit and the substrate;
• another condensing component and the second color sub-pixel unit are arranged in one of the plurality of openings of the light shielding layer, and the another condensing component is disposed between the second color sub-pixel unit and the substrate;
• and the one condensing component and the another condensing component are used for converging emitted light of the first color sub-pixel unit and the second color sub-pixel unit, respectively.

A method for preparing a color film substrate, comprising:

• providing a substrate;
• preparing a light shielding layer on the substrate, and patterning the light shielding layer to form a plurality of openings;
• printing a first ink in two of the openings using an ink jet printing process to form two condensing components in the two of the openings respectively;
• and
• preparing a first color sub-pixel unit and a second color sub-pixel unit on the two condensing components, wherein one of the two condensing components and the first color sub-pixel unit are arranged in one of the plurality of openings of the light shielding layer, and the one of the two condensing components is disposed between the first color sub-pixel unit and the substrate;
• another of the two condensing components and the second color sub-pixel unit are arranged in one of the plurality of openings of the light shielding layer, and the another of the two condensing components is disposed between the second color sub-pixel unit and the substrate;
• and the one condensing component and the another condensing component are used for converging emitted light of the first color sub-pixel unit and the second color sub-pixel unit, respectively.
