A non-light-emitting cell 100c is provided between pixels 100a and 100b. In formation of the pixel 100a, ink for forming an organic light-emitting layer is dripped into sub-pixels 100a1, 100a2, 100a3 in this order. This also applies to the pixel 100b. However, such ink is not dripped into the non-light-emitting cell 100c since the organic light-emitting layer is not formed in the non-light-emitting cell 100c. Regarding banks 105c and 105d defining the sub-pixel 100a3 of the pixel 100a, an inclination angle θd3 of a wall 105d3 of the bank 105d is larger than an inclination angle θc3 of a wall 105c3 of the bank 105c. Meanwhile, regarding banks 105e and 105f defining the sub-pixel 100b1, an inclination angle θe1 of a wall 105e1 of the bank 105e is equivalent to an inclination angle θe1 of a wall 105f1 of the bank 105f.

Regarding a bank 105d between the sub-pixel 100a3 and the non-light-emitting cell 100c, an inclination angle θd3 of a wall 105d3 is larger than an inclination angle θdc of a wall 105dc. On the other hand, regarding a bank 105e between the sub-pixel 100b1 and the non-light-emitting cell 100c, an inclination angle θe1 of a wall 105e1 is equivalent to an inclination angle θec of a wall 105ec.

The invention relates to a soft baking method which comprises the following steps: a substrate is heated by a heating plate, wherein, the heating plate is provided with at least one thimble for supporting the substrate; when the substrate is heated, the position where the thimble supports the substrate is changed. In the invention, the position where the thimble supports the substrate is changed when heating is carried out, and the thimble is not contacted with the same position of the glass substrate for a long time; therefore, the problem of uneven film thickness after drying caused by overhigh local temperature on the glass substrate can be avoided.

A semiconductor device comprises a photoelectric conversion portion formed on a semiconductor substrate, a first transparent film provided on the photoelectric conversion portion, and an interlayer lens provided on the first transparent film at a position corresponding to the photoelectric conversion portion, in which the interlayer lens has a higher refractive index than the first transparent film, and at least one of upper and lower surfaces of a second transparent film formed with a thin film multilayer structure of two or more types of compounds is formed to have a protruded shape.

The invention relates to an ink-jet printing method, device, and system, computer equipment, and a storage medium. The ink-jet printing method includes the following steps: the number of multiple participation spray nozzles is obtained for multiple preset ink-jet angles; the number of the participation spray nozzles includes the number of spray nozzles participating in ink-jet when a printing taskis performed; an ink-jet angle with a maximum number of the participation spray nozzles is utilized as a target ink-jet angle; and the target ink-jet angle is transmitted to ink-jet printing equipment for the ink-jet printing equipment to perform the printing task according to the target ink-jet angle. Through the ink-jet printing method of the invention, the performance of an OLED device is improved.

A dope including a polymer and a solvent is discharged from a casting die (30) to a casting drum (31) while forming a casting bead (38). An upstream side (38a) area of the casting bead (38) is decompressed by a decompression chamber (36) to (atmospheric pressure—300)Pa. Air shielding plates (70, 71) are provided inside the decompression chamber (36). Openings (90) are respectively formed in upper half portions of the air shielding plates (70, 71). A distance L (mm) between a contact position A of the casting bead (38) and the air shielding plate (70) is set in the range of 20 mm to 100 mm. After the casting bead (38) forms a casting film (39) on the casting drum (31), the casting film (39) is peeled and dried to obtain a TAC film.

The problem addressed by the present invention is providing a die having a lip with a specific shape so as to be able to obtain a uniformly applied film with minimal occurrences of variations in thickness and application streaking when applying a composition for anisotropic dye film formation. The problem above is addressed by a method for manufacturing an anisotropic dye film that includes a step for applying a composition for anisotropic dye film formation onto a substrate using a die coater. The method for manufacturing the anisotropic dye film is characterized by the die coater having a front lip positioned on the direction of travel side of the die coater and a rear lip positioned on the side opposite to the direction of travel, and both lips having respective lip lower edge surfaces facing the substrate. Letting A be the length for the lower edge surface of the front lip along the direction of travel and B be the length of the lower edge surface of the rear lip along the direction of travel, A>B. The viscosity of the composition for anisotropic dye film formation is 10 cP or greater.

The invention provides a coating device for weakening the influence of external vibration, in particular for inhibitting resonance caused by external vibration effectively. An anti-resonance portion (31) is filled in a suppoting carrier (2) and a cove (30) of square pipes (20, 21a-21c) of a slit nozzle travel mechanism. Beacuse filling the anti-resonance portion in square pipes can change the natural vibration frequency of a base (1), a resonance state can not be got because of external vibration.

The invention supplies an optical recording medium with three-dimensional data image and its preparation method, which comprises a base plate and complex recoding layer that composes a luminescent material of low degree of polymerization and forms on base plate. For there is high quantum efficiency and Stoke shift for the luminescent material, when use laser light t read the medium, the recording layer will be excited luminescence signal with enough strength. Thereby, the medium of this invention has very fine recording sensitivity and read characteristic without adding signal amplification structure or material.

The invention provides a display device packaging method, which comprises the following steps: providing a display device on which a first inorganic layer covering the display device is formed; printing ink on the first inorganic layer by inkjet printing; heating the ink; irradiating the ink by the ultraviolet light to cure the ink, forming an organic layer on the first inorganic layer, and heating the ink before being cured, so that the ink is quickly leveled, the problem of non-uniform film thickness of the organic layer formed by the ink is solved, and the mura defect is improved.
