Abstract: A composite transparent film, a preparation method thereof and a method for continuous digital light processing ceramic 3D printing based on the same are provided. The method selects a mixture of silica microspheres and PDMS to form a composite film on which silica is used to form a hydrophobic layer. Combined with specific optimized parameters, the film is more suitable for continuous digital light processing ceramic 3D printing, which can realize the continuous printing of ceramic slurries, solve the problem of delamination of printed pieces obtained by the existing 3D printing method of ceramics, improve the printing accuracy, and decrease the printing costs.

Abstract: A display apparatus and a driving method of a display panel are provided. A display driver drives the display panel so that the adjacent pixels in each of first display segments and each of the second display segments on a scan line have opposite polarities, and two pixels located on junction section of adjacent first display segment and second display segment have the same polarity.

Abstract: An information update system includes a first portable terminal, a server and a second portable terminal. The first portable terminal captures a facial image of a user of the first portable terminal and obtains facial characteristic information and corresponding EXIF information of the facial image. The server stores photo albums and facial characteristic information and corresponding EXIF information of each photo album. The second portable terminal runs an application with a preset background image. The server matches the received facial characteristic information and corresponding EXIF information to the stored facial characteristic information and corresponding EXIF information, and further outputs matching information including at least one of the stored photo albums. The second portable terminal updates the photo album to the application to replace the preset background image.
