  • Patent number: 12207498
    Abstract: An object of the present disclosure is to implement a coloring pattern with a constant illuminance value on an electrode substrate to thereby increase display reliability and lifetime while reducing delamination of the hole transport layer (HTL) in the post-process. That is, when the roughness of the pattern after post-baking treatment is low, it may cause delamination of the hole transport layer (HTL) and a decrease in lifetime due to defective pixels, and thus a certain roughness can be obtained by minimizing the surface flow by leaving the substrate at a high temperature during post-baking treatment according to the present disclosure.

  • Publication number: 20240419070
    Abstract: Provided is a method for preparing a pixel defining layer, which is not only to ensure vivid colors, but also to increase display reliability and lifespan by creating one or more layers through one-time process of performing coating, prebaking, exposure, development, post-exposure, and post-heat treatment and thus implementing a colored pattern capable of reducing the process time on the electrode substrate, wherein the method unifies the processes of two layers of the PDL and CS layers of the organic light emitting diode panel into one by including the colorant according to the present disclosure, and shortens the process time by adjusting the UV active ray transmittance of the photomask to three sections of 0% (non-exposed portion), 20 to 50% (Half-tone), and 100% (Full-tone) in order to create a step height in the pattern after the development process is completed and thus forming two layers at once.
