Embodiment Construction
[0049] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0050] Embodiments of the present invention provide an alignment film coating assembly, such as figure 1 As shown, the alignment film coating assembly 100 includes a coating body 110 and a detection mechanism 120 .
[0051] The coating body 110 includes a relief plate configured to form an alignment liquid on the surface of a current substrate to obtain an alignment film, and the current substrate is placed on a carrier base. The letterpress is the APR version, and the letterpress is made of UV-cured polyurethane resin. In order to complete the coating process of the alignment film, usually the dispenser first adds the alignment liquid to the contact position between the cot roller and the scraper, and the scraper evenly coats the ali...

The invention discloses a coating method, component and system of an alignment film and belongs to the technical field of liquid crystal display. The coating component of the alignment film comprisesa coating body and a detection mechanism, the coating body comprises a relief printing plate, the relief printing plate is arranged in the mode that alignment liquid is formed on the surface of a current substrate to obtain the alignment film, and the current substrate is placed on a bearing base table; the detection mechanism is arranged above the current substrate and is arranged to determine adeviation value of an actual area and a preset area of the alignment film on the surface of the current substrate based on a picture of the current substrate which is provided with the alignment film,so that the bearing base table adjusts the position of the next substrate to be coated based on the deviation value. According to the coating method, component and system of the alignment film, the problems are solved that when the deviation value of the actual area and the preset area of the alignment film is manually determined, time and labor are consumed, the efficiency is low, and the accuracy is low; the effects are achieved that manual determination of the deviation value is not needed, time and labor are saved, and the coating efficiency and accuracy are improved. The coating method,component and system of the alignment film are suitable for coating of the alignment film.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an alignment film coating method, an alignment film coating assembly and an alignment film coating system. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has been widely used due to its thin body, power saving, and no radiation. Examples are LCD TVs, mobile phones, personal digital assistants, digital cameras, computer screens or laptop screens, etc. The display panel of the liquid crystal display device includes a color filter substrate, an array substrate disposed opposite to the color filter substrate, and a liquid crystal layer filled between the color filter substrate and the array substrate. The color filter substrate and the array substrate are formed with alignment films for inducing alignment of liquid crystal molecules. [0003] In the related art, usually, the glue dispenser adds the alignment liquid to the contact...
