Problems solved by technology
[0004] The current method used by the equipment is the optical measurement method. Through image processing, the volume of the ink drop is calculated, and the nozzle is adjusted according to the calculated result each time. However, the error of this adjustment method is relatively large, and the process of calculating the volume of the ink drop troublesome

The invention discloses an adjusting device and an adjusting method for the droplet volume, which are used for improving the convenience of adjusting and measuring and reducing the measuring error. The adjusting device includes a measuring substrate, and at least one measuring unit is provided, and each measuring unit includes a first measuring groove, at least one second measuring groove, a third measuring groove adjacent to the second measuring groove, the first measuring groove The volume of the measuring groove is larger than the total volume of all the second measuring grooves, and the height of the side wall shared by the first measuring groove and the adjacent second measuring groove is smaller than that of the first measuring groove without the second measuring groove The height of the side wall on one side of the groove, the total volume of the third measuring groove is less than the total volume of the second measuring groove, the height of the side wall shared by the second measuring groove and the third measuring groove adjacently arranged is less than The height of the side wall of the side of the second measuring groove that is not provided with the third measuring groove; the detection device detects whether there is a liquid drop in the first measuring groove, the second measuring groove and the third measuring groove.
Description
technical field [0001] The invention relates to the technical field of display device preparation, in particular to a liquid droplet volume adjustment device and adjustment method. Background technique [0002] In general, an inkjet head is a device that ejects ink droplets onto a desired position of a recording medium to form an image. Inkjet heads are classified into two types according to the inkjet mechanism. The first is a thermal inkjet head that ejects ink droplets by thermal energy due to the expansion force of air bubbles generated in ink. The other is a piezoelectric inkjet head that ejects ink droplets by pressure applied to ink due to deformation of a piezoelectric body. [0003] Recently, inkjet heads have been used in the imaging field and other fields. For example, inkjet heads have been used to manufacture color filters for liquid crystal displays (LCDs). Color filters have been manufactured by dyeing, pigment dispersion, printing and electrodeposition. ...
