An inkjet unit and an inkjet device are provided. The inkjet unit includes a liquid compartment that forms a liquid receiving cavity and a jetting nozzle that forms a liquid discharge opening. The liquid receiving cavity is in communication with the liquid discharge opening to allow a liquid contained in the liquid receiving cavity to jet outward through the liquid discharge opening. The inkjet unit further includes a gas supply device. The gas supply device delimits a gas flow channel. The gas flow channel has a gas spray orifice that is arranged to surround an outer wall of the jetting nozzle. Accordingly, the gas supply device can spray a gas through the gas spray orifice toward the circumference of the jetting nozzle to clean the jetting nozzle, keeping liquid from attaching to the circumference of the jetting nozzle and thereby preventing the liquid from blocking the liquid discharge opening.

The present invention discloses a method of forming an alignment film for use in a liquid crystal display (LCD). The method includes: Provide a glass substrate and dispose an ITO film on the glass substrate. Next, set the thickness of the alignment film. Next, determine the spray volume of thin film material droplets based on the length and the width of the glass substrate. Next, spray a plurality of thin film material droplets in rows on the glass substrate through a plurality of nozzles of an inkjet head. The thin film material droplets are distributed in an approximate equilateral triangular pattern. The thin film material droplets in the shape of an approximate equilateral triangle can reduce instability when spreading on the glass substrate, achieving a target of optimized coatings. Finally, process an alignment material thin film which is formed after the thin film material droplets spread to form an alignment film.

A cipher engine performs cipher processing (encrypting/decrypting) on logical data streams in a physical data stream in a storage device. As the physical data stream changes from a first logical data stream to a second logical data stream, and the cipher engine switches from cipher processing the first logical data stream to the second logical data stream, cipher information of the first logical data stream is stored in a cipher state memory, cipher information of the second logical data stream is retrieved from the cipher state memory, and the cipher engine resumes cipher processing the second logical data stream using the cipher information of the second logical data stream. Advantageously, a virtually unlimited number of logical data streams is supported and duplicate cipher hardware is avoided.

The present invention discloses a Liquid Crystal Display (LCD), a LCD substrate and a LCD manufacturing method. The boundary of the substrate, to be coated with alignment liquid, is provided with a boss or a groove which is used to prevent the alignment liquid from diffusing. Because the substrate of the LCD is provided with the boss or groove for preventing the alignment liquid from diffusing, the boss can prevent the alignment liquid from diffusing, and the groove can absorb the diffused alignment liquid. As a result, the alignment liquid is prevented from forming nonuniform boundary on the substrate with surface section difference, and the uniform boundary is formed; furthermore, the boundary of the active area of the LCD further deflects to the alignment layer, and the range of the active area is expanded. Under the action of the blockage by the boss or groove, the boss or groove can deflect to the sealant area, i.e. the boundary of the alignment layer deflects to the sealant area, thereby further expanding the range of the active area.

A coating method for liquid crystal alignment film of TFT-LCD including: forming a layer of hydrophobic film on a TFT/CF substrate corresponding to a non-display area, the hydrophobic film separates the TFT/CF substrate into a plurality of rectangular opened areas which are separated from each other, each of the rectangular opened areas corresponds to a display area and its outer frame is formed by the hydrophobic film; and coating of a liquid of a material of an alignment film along a boundary of the rectangular opened area. Accordingly, edge waves caused by spreading of drips of the material of the alignment film can be reduced, so that a precision of printing of the alignment film can be controlled effectively.

摘要:
Video data in an encoded frame is reduced by adjusting orthogonal transform coefficients in the encoded frame during trick play operation such as fast forward or fast reverse. The orthogonal transform coefficients are adjusted by selecting essential orthogonal transform coefficients with high energy and non-essential orthogonal transform coefficients with low energy, maintaining or strengthening the essential orthogonal transform coefficients and attenuating or removing the non-essential orthogonal transform coefficients. In an MPEG bit stream, the encoded frame is an I-frame and the orthogonal transform coefficients are discrete cosine transform (DCT) coefficients.
