  • Publication number: 20160003448
    Abstract: A color filter layer, a color film substrate including the color filter layer, and a display apparatus including the color filter substrate are provided. The invention relates to the field of display technology and can solve the problem that the color membrane substrates in the prior art have a relatively low utilization ratio of light. The color filter layer of the invention comprises a filter membrane and a light conversion layer disposed on the light entering side of the filter membrane. According to the invention, the light of other frequencies in incident light can be converted into light having the same spectral characteristics as the respective filter membranes, due to the presence of the light conversion layer. Therefore, the utilization ratio of light and the display brightness can be improved, and thus energy consumption can be saved effectively and the display performance can be enhanced.

  • Publication number: 20150370163
    Abstract: A grayscale mask plate and method of fabricating the same, a color film substrate and method of fabricating the same, and a display device are disclosed. The grayscale mask plate comprises a transparent substrate and a light blocking layer on the transparent substrate. The light blocking layer comprises an exposure region with an optical translucent film which has a light blocking ratio decreasing gradually or stepwise from a center of the optical translucent film to an edge of the optical translucent film. As a result, the intensity of light transmitted through the exposure region is uniform, such that a post spacer fabricated by the grayscale mask plate has a relatively flat top face. Thus, the post spacer exhibits a linear variation in its hardness under the action of an external force.
