Problems solved by technology

[0003] At present, OLED devices are mainly prepared by evaporation or inkjet printing, but evaporation faces problems such as mask (mask) deformation, substrate film wear, low material utilization rate, and high equipment investment in large-scale applications. Therefore, the current The development trend is to adopt the process of inkjet printing
In inkjet printing OLED, there are two main structural designs for pixels: one is the red, green and blue sub-pixel unit SBS (Side by Side, arranged side by side) pixel arrangement design, this design consumes less ink, but It requires high equipment precision, easy to mix colors, and has a large yield loss; the other is the Line-Bank (linear bank) pixel arrangement design, which is to print a whole line of sub-pixels of the same color in the same Bank area, that is, Red, green and blue three-color sub-pixel units are printed as a whole pixel. This design consumes a lot of organic ink materials on large-sized OLED devices, resulting in high cost
[0004] Therefore, there is a need for a new display panel, its preparation method, and display device to solve the problem of high printing accuracy in the pixel structure design of the existing display panel generated by inkjet printing, resulting in a large yield loss or printing The technical problem of high production cost due to high consumption of ink materials
