Embodiment 1
[0067] see figure 1 , the embodiment of the present application provides a preparation method of a pixel structure, the preparation method includes the following steps:
[0068] S11, depositing a luminescent material definition layer 104 on the substrate 10;
[0069] S12. Etching out the first luminescent material cavity 11 and the second luminescent material cavity 12 in the luminescent material definition layer 104, and the cavity of the first luminescent material cavity 11 communicates with the cavity of the second luminescent material cavity 12 ;
[0070] S13, spraying a luminescent material into the first luminescent material cavity 11 to form a first luminescent material layer 5;
[0071] S14. Detect whether the luminescent material in the first luminescent material cavity 11 overflows into the second luminescent material cavity 12 through the communication channel 13 to form the second luminescent material layer 6;
[0072] S15 , when the second luminescent material ...
Embodiment 2
[0111] see Figure 5 to Figure 7 , a pixel structure, including a luminescent material definition layer 104 and at least one pixel light emitting unit disposed on the luminescent material definition layer 104, the pixel light emitting unit includes a first luminescent material cavity 11 and a second luminescent material cavity 12, the first light emitting The cavity of the material cavity 11 communicates with the cavity of the second luminescent material cavity 12 .
[0112] In the application, the luminescent material is sprayed into the first luminescent material cavity 11 by inkjet printing, the luminescent material is preferably an organic photoluminescence material, and whether there is a luminescent material in the second luminescent material cavity 12 is detected; , when the luminescent material in the first luminescent material cavity 11 overflows into the second luminescent material cavity 12, and the detection mechanism detects the luminescent material layer in the s...
Embodiment 3
[0146] The present application also proposes a display panel, including a pixel structure formed on a substrate 10, wherein at least one of the plurality of pixel structures is the above-mentioned pixel structure, and the specific structure of the pixel structure refers to the above-mentioned embodiments. This display The thicknesses of the first luminescent material layers 5 in the plurality of first luminescent material cavities 11 in the plurality of pixel structures in the panel are all the same, so that the brightness of the plurality of pixel structures remains uniform during operation. The luminescent raw materials are saved, and the uniformity of the luminescent material coating can be ensured, so that the luminous brightness of the multiple pixel structures in the display screen is uniform, and the color transition is natural. Since this display panel adopts all the technical solutions of all the above-mentioned embodiments, it is also All the beneficial effects brough...
