  • Publication number: 20220147255
    Abstract: In a method of storing data block, a storage device has stored a plurality of data block groups, each data block group having a common part that is contained in another data block in that group. For a target block to be stored, the storage device selects from the data block groups a target data block group has one data block whose common part is identical to a part of the target data block. The storage device then saves the target block by storing a target reference block of the target data block group and differential data between the target data block and the target reference block.

  • Patent number: 11329254
    Abstract: A display panel and a display device are provided and have a base substrate, a blocking wall, an encapsulation layer, and a touch capacitor layer. By forming a second-layer blocking wall and a first-layer blocking wall to form a second blocking wall, a height of the second blocking wall is increased. Further, a blocking block is disposed between the second blocking wall and the first blocking wall, thereby increasing a thickness and a height of the blocking wall. When inkjet printing an organic layer, a slope at edges of a display area is relatively smooth, which can make an entire encapsulation layer relatively flat, thereby reducing a height difference of wirings at the edges and avoiding a problem of inaccurate exposure and focus.
