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 application provides a glue-discharging rate adjusting system, and the system comprises a color film coating device and a first measuring device; a first measuring device is used for acquiring a wet film parameter difference value between a wet film measuring parameter of a first wet film and a wet film preset parameter and feeding the wet film parameter difference value back to the color filmcoating device, the first wet film is a wet film formed by the color film coating device based on the current glue-discharging rate, and both the wet film measuring parameter and the wet film presetparameter comprise chroma or thickness; and the color film coating device is used for adjusting the current glue-discharging rate according to the wet film parameter difference value and the corresponding relation between the wet film parameter difference value and the glue-discharging rate difference value so that the wet film parameter difference value of a second wet film is smaller than the difference value threshold value, and the second wet film is a wet film formed by the color film coating device based on the adjusted glue-discharging rate. The system provided by the invention adjuststhe glue-discharging rate according to the wet film parameter difference value of the wet film, and 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...
