Problems solved by technology

The current measurement method can only measure the size of the colloid along the horizontal or vertical direction, but cannot measure the size of the colloid along the oblique direction when the colloid is applied obliquely, that is, the size of the colloid coated with special shapes cannot be measured

Embodiment Construction

[0021] The main purpose of this application is to obtain in advance the size ratio between the reference object and the reference object when it is imaged on the screen. According to this size ratio relationship, it is only necessary to obtain the imaging size of the colloid when it is imaged on the screen, and then the colloid can be calculated. Real size, the measurement of imaging size is not affected by the shape of the colloid coating, so the measurement of the real size of the colloid will not be affected by the shape of the colloid coating (including oblique coating of the colloid). Here, the application can measure the colloid The size in the oblique direction can realize the size measurement of special-shaped coating colloid.

[0022] Wherein, the colloid may be a sealing sealant in the structure design of the liquid crystal display panel, and may also be applicable to any other structural devices coated with colloid.

[0023] The following clearly and completely desc...

Abstract

The invention discloses a method and a device for measuring size of a colloid. The measuring method comprises the following steps of: obtaining in advance a dimensional proportion of a reference object and an image of the reference object imaged on a screen; keeping shooting magnification of a lens unchanged, shooting the colloid with the lens, and displaying the image of the shot colloid on the screen; obtaining an imaging size of the colloid imaged on the screen; and obtaining an actual size of the colloid according to the imaging size and the dimensional proportion. According to the methodand the device for measuring the size of the colloid, the size of the colloid in an inclined direction can be favorably measured, and size measurement of special-shaped coating colloids is realized.

Description

technical field [0001] The present application relates to the field of display, in particular to the field of packaging of electronic devices, and in particular to a method and device for measuring colloid size. Background technique [0002] In the traditional colloid coating process, the glue is dripped on the area to be protected, and then cured. The cured colloid can play the role of water vapor barrier and anti-corrosion. In the liquid crystal display panel, the colloid is also called the sealant, which is mainly used to limit the area where the liquid crystal cell is located, as well as to bond the color filter substrate and the array substrate, and to control the thickness of the liquid crystal cell. It is necessary to measure the size of the above colloids. The current measurement method can only measure the size of the colloid along the horizontal or vertical direction, but cannot measure the size of the colloid along the oblique direction when the colloid is applie...
