Embodiment Construction
[0032] In order to make the purpose, technical solutions and advantages of the application clearer, the technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the embodiments of the application. Obviously, the described embodiments are part of the implementation of the application. example, not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0033] At present, in order to ensure the display quality of the display panel, the thickness of the color filter substrate needs to be strictly controlled, that is, the thickness of the color photoresist on the color filter substrate needs to be controlled within the effective range of the set thickness value. In the prior art, the method of measuring the chroma or thickness of the dry film formed by ...

The present application provides a system for adjusting glue spit rate, which system includes: a color film coating device and a first measuring device; the first measuring device is used to obtain wet film measurement parameters and wet film preset parameters of the first wet film The difference between the wet film parameters, and the wet film parameter difference is fed back to the color film coating device. The first wet film is the wet film formed by the color film coating device based on the current spit rate. The wet film measurement parameters and wet The preset parameters of the film include: chroma or thickness; the color film coating device is used to adjust the current spit rate according to the wet film parameter difference, and the corresponding relationship between the wet film parameter difference and the spit rate difference, so that The wet film parameter difference of the second wet film is less than the difference threshold, and the second wet film is a wet film formed by the color filter coating device based on the adjusted spit rate. The system provided by the present application adjusts the spit rate according to the wet film parameter difference of the wet film, which can improve the adjustment efficiency.
Description
technical field [0001] The present application relates to the technical field of color film preparation, and in particular to a system for adjusting glue spewing rate. Background technique [0002] The display panel is formed by pairing an array substrate and a color filter substrate, and a liquid crystal is arranged between the array substrate and the color filter substrate. The color filter substrate includes a plurality of color filter units, and each color filter unit is composed of three color pixel units, namely red, blue and green pixel units. At present, the color filter substrate is formed by coating a color photoresist glue on the substrate by a color filter coating device. [0003] In the prior art, the chroma or thickness of the dry film formed by coating the colored photoresist glue on the substrate is measured by measuring equipment. , the technician adjusts the spit rate of the coating device so that the chroma or thickness of the dry film reaches the set va...
