The present invention is a substrate for a display, the substrate having a film B including a polysiloxane resin on at least one surface of a film A including a polyimide resin, wherein the film B contains inorganic oxide particles therein, and the present invention has an object to provide a substrate for a display: being able to be applied to a color filter, an organic EL element, or the like without the need to carry out any complex operations; allowing high-definition displays to be manufactured; and being provided with a low CTE, a low birefringence, and flexibility.

An alignment coating structure for a substrate includes at least one substrate, and each of the substrates has a blind via; an alignment plate has at least one opening; the alignment plate covers on the substrate; the opening corresponds to the blind via; and a printing mechanism for transferring polyimide liquid on the alignment plate to a region out of the blind via on the substrate according to a preset printing direction. An alignment coating method for a substrate, including disposing an opening on an alignment plate makes the opening face a blind via in alignment coating. This makes the location where the blind via will not be printed by polyimide liquid, thereby increasing the liquid crystal arrangement randomness of the location where the blind via is, making the optical path be scattered to a certain extent, thereby prevent from occurrence of a Newton's ring or a rainbow pattern.

Various embodiments directed towards methods of applying sizing to fibers are disclosed herein. In some embodiments, solvent can be used to dissolve a sizing material into a solution, which can then be used to coat the fibers. In some embodiments, a water bath is used to coagulate a sizing on the fiber surface and to remove the remove solvent after coating the fibers, so that water vapor can be created during a subsequent drying step as opposed to solvent vapors. In some embodiments, strong acids or strong bases can be used as the solvent.

A display device includes a non-transmissive display section and a transmissive display section. The non-transmissive display section includes a base member including a first polyimide. The transmissive display section includes a base member including a second polyimide that has higher transparency than the first polyimide. The base member of the non-transmissive display section and the base member of the transmissive display section are connected in a connecting section. A bending portion is provided in the base member of the non-transmissive display section or the base member of the transmissive display section. The connecting section and the bending portion do not overlap each other.

A coating for a medical device or appliance may include a fluoropolymer and a polyimide. Such coatings may provide a lubricious exterior surface that facilitates insertion or displacement of a medical device in a body lumen. Some coatings that include a fluoropolymer and a polyimide may, among other functions and characteristics, provide increased strength and/or durability relative to some other coatings.

A method for fabricating a display panel including a bending area includes: providing a substrate; forming a first flexible layer on the substrate; forming an organic layer on the first flexible layer, wherein a wavelength of light absorbed by the organic layer is different from a wavelength of light absorbed by the first flexible layer; irradiating a part of the organic layer in the bending area with a laser to make at least a portion of the part of the organic layer a carbonized layer, thereby forming a spacer layer; forming a second flexible layer covering the first flexible layer and the spacer layer, wherein the first flexible layer and the second flexible layer are made of a same material and separated by the spacer layer; and cutting a part of the substrate and a part of the first flexible layer in the bending area.

The present disclosure provides an apparatus for removing bubbles in a flexible substrate. The flexible substrate includes a baseplate and a polyimide layer coated on the baseplate. The apparatus includes a chamber including a top wall, a sidewall, and a bottom wall, wherein the top wall, the sidewall, and the bottom wall define an accommodation space; a heating plate disposed in the accommodation space; and a cooling conduit embedded in at least one of the top wall and the sidewall of the chamber.

A method of forming a wear-resistant coating on an article includes depositing a chromium coating on a substrate of the article, and subsequently heating the coated article to enhance a plurality of through-cracks within the chromium coating. The method further includes applying a liquid filler material to the coated article such that at least one of the plurality of through-cracks is at least partially occupied by the filler material, and solidifying the liquid filler material.

Disclosed are an organic barrier film, a preparation method of the organic barrier film, and a quantum dot device.
