  • Publication number: 20120038862
    Abstract: A liquid crystal display panel and a color filter substrate are provided. The color filter substrate includes a substrate, a stacked layer, a phase compensation film and a second alignment film. The stacked layer is disposed on the substrate and includes a first alignment film and a color filter layer having a phase compensation effect, wherein the first alignment film and the first alignment film are stacked on each other. The phase compensation film is disposed on the stacked layer. The second alignment film is disposed on the phase compensation film. Therefore, a number of fabrication processes of the color filter substrate can be reduced.

  • Publication number: 20050140764
    Abstract: An ink-jet printing apparatus for printing at least one organic material on a substrate comprises a delivering chamber, a loading mechanism, at least one ink-jet printing mechanism, a heat treatment process mechanism and an unloading mechanism. In this case, the delivering chamber has a delivering unit, which carries the substrate from the loading mechanism and carries the substrate to the unloading mechanism. The ink-jet printing mechanism connects to the delivering chamber and prints the organic material on the substrate. The heat treatment process mechanism connects to the delivering chamber and heats the substrate on which the organic material is formed. The unloading mechanism connects with the delivering chamber.

  • Publication number: 20040082089
    Abstract: An organic light-emitting device having a porous desiccant layer therein and a method for fabricating the same is provided. The porous desiccant layer is manufactured by spreading a liquid desiccant on a surface, forming air bubbles (by activating some vesicant or injecting gas into the liquid desiccant) and curing the liquid desiccant. The porous desiccant comprises solidified hardening glue having bubbles and lots of desiccant particles or powder distributed evenly therein. Some residual vesicant may remain inside the solidified hardening glue after activation. The bubbles inside the porous desiccant enhance the absorption rate and efficiency of the desiccant so that moisture and gaseous oxygen inside the OLED package can be absorbed rapidly.
