Referring to FIG. 7, the present invention further provides a method for preparing a display panel 10. The method for preparing the display panel 10 includes steps S100, S200, S300, and S400. Each step is described in detail below.

In step S100, a light emitting layer 100 is provided. The light emitting layer 100 may be a liquid crystal light emitting or an organic electroluminescent material.

In step S200, a light transmitting layer 200 is formed on one side of the light emitting layer 100.

In step S300, first barrier dams 300 and second barrier dams 400 are formed on the surface of the light transmitting layer 200 away from the light emitting layer 100 at intervals. The method for forming the first barrier dam 300 and the second barrier dam 400 includes forming a thin film by chemical vapor deposition, and then forming the thin barrier dam by patterning. The material forming the first barrier dam 300 and the second barrier dam 400 may be an organic material, such as polyimide, or may be one or more materials of nitride, oxide, and oxynitride.

In a further embodiment, the separation distance between the first barrier dam 300 and the second barrier dam 400 is at least one pixel width.

In step S400, a first polarizing layer 500 is formed on the surface of the light-transmitting layer 200 away from the light-emitting layer 100 and between the first barrier dam 300 and the second barrier dam 400. It can be understood that the height of the first blocking dam 300 and the second blocking dam 400 is at least equal to the height of the first polarizing layer 500.

By adopting the preparation method of the present invention, the accuracy of the polarizing layer (first polarizing layer 500) can be made to multiple pixel sizes or one pixel size, and the display panel can be made thinner. The existing method of externally attaching a polarizer to a display panel is limited by the process of attaching the polarizer. The polarizer must be at least a few hundred micrometers with poor accuracy, and an extra layer of adhesive is required to attach the polarizer. , Thicker.

Referring to FIG. 8, in a further embodiment, the step of “forming a first polarizing layer 500 on the surface of the light-transmitting layer 200 away from the light-emitting layer 100 and between the first barrier dam 300 and the second barrier dam 400” includes step S410. And step S420. Details are as follows.

In step S410, a first polarizing material is placed on the surface of the light-transmitting layer 200 away from the light-emitting layer 100 and between the first barrier dam 300 and the second barrier dam 400. The first polarizing material may be polyvinyl alcohol. It can be understood that the first polarizing material may be liquid. The first blocking dam 300 and the second blocking dam 400 are used to block the liquid-like first polarizing material from wanton diffusion.

Step S420, forming a first polarizing layer 500 by orienting the first polarizing material through curing. It can be understood that before the orientation of the curing, the molecules in the first polarizing material are disordered and there is no regularity. After the orientation of the curing, the molecules in the first polarizing material are arranged in order. That is to say, after the first polarizing layer 500 is formed, the molecules therein are arranged in an order, and the light emitted from the light emitting layer 100 passes through the molecules in the first polarizing layer 500 and is filtered to form a first polarized light. It can be understood that the direction of the ordered arrangement of molecules in different polarizing materials can be determined by different curing orientations.

In a further embodiment, the "curing orientation" includes light wave orientation, electromagnetic field orientation, or heating orientation. It can be understood that when using light wave orientation, there are different directional light waves for different polarizing materials. Selecting directional light waves that match the polarizing material, orienting the material link direction, so that the molecules are ordered. For the same polarizing material, there may be multiple directional light waves, so that the polarized material emits polarized light with different directions after being oriented. When electromagnetic field orientation is used, the same, for different polarizing materials, there are different directional electromagnetic waves. When using heating orientation, different polarizing materials have different directional heating heat. In short, for different polarizing materials, a matching curing orientation method can be selected to form a polarizing layer.

Using curing orientation to orient the material link direction can achieve the pixel level, which is traditionally impossible to form a polarizer through a stretching process. When light wave orientation is used, the light wave can be a point source, used to cure polarized pixel-level polarized layers, and the light wave can also be a line source, used to cure a row or column of polarized layers, or a surface source, used to cure a piece of polarized light. Floor.

The polarizing layer (first polarizing layer 500) formed by using the curing orientation can finally generate high-purity polarized light. Because the polarizing layer is liquid before curing and orientation, the polarizing material is uniformly dispersed, and the materials are ordered after curing and orientation, so it can produce high-purity polarized light.

Referring to FIG. 9, in a further embodiment, the step of “placing a first polarizing material on the surface of the light transmitting layer 200 away from the light emitting layer 100 and between the first barrier dam 300 and the second barrier dam 400” includes steps S411 and Step S412. Details are as follows.

In step S411, a liquid first polarizing material is dropped onto a surface of the light-transmitting layer 200 away from the light-emitting layer 100 and between the first blocking dam 300 and the second blocking dam 400 to obtain a droplet-shaped first polarizing material. It can be understood that the liquid first polarizing material can be ejected through the print head, and the print head is placed directly above the light-emitting layer 100, and the direction of the liquid first polarizing material ejected by the head is located at the first blocking dam 300. And the second blocking dam 400 to ensure that the first polarizing material drips between the first blocking dam 300 and the second blocking dam 400.

In step S412, the first polarizing material in the form of a droplet is spread to form the first polarizing material in the form of a liquid layer. The droplet-shaped first polarizing material may be formed into a liquid layered first polarizing material by natural spreading or external factors to ensure that the surface of the first polarizing material is flat, so that the surface of the subsequent first polarizing layer 500 is flat. , Conducive to polarizing effect.

In a further embodiment, the “forming the first polarizing layer 500 by curing the first polarizing material” includes forming the first polarizing layer 500 by curing the first polarizing material in a liquid layer.

In a further embodiment, the method for preparing the display panel 10 further includes steps S500 and S600. Details are as follows.

In step S500, a third barrier dam 600 is formed on a side of the second barrier dam 400 away from the first barrier dam 300 and on a surface of the light transmitting layer 200 far from the light emitting layer 100. The method of forming the third barrier dam 600 includes forming a thin film by chemical vapor deposition, and then forming the thin film by patterning. The material forming the third barrier dam 600 may be an organic material, such as polyimide, or one or more materials selected from the group consisting of nitride, oxide, and oxynitride.

In step S600, a second polarizing layer 700 is formed on the surface of the light-transmitting layer 200 away from the light-emitting layer 100 and between the second barrier dam 400 and the third barrier dam 600. It can be understood that the height of the second blocking dam 400 and the third blocking dam 600 is at least equal to the height of the second polarizing layer 700.

In a further embodiment, the polarizing materials of the first polarizing layer 500 and the second polarizing layer 700 are different. In this way, the directions of polarized light formed by filtering through the first polarizing layer 500 and the second polarizing layer 700 are different.
