Problems solved by technology

However, the disadvantage of this approach is that the opening of the peripheral plastic frame will cause acid liquid to enter between the box plastic frame and the peripheral plastic frame during the subsequent thinning process, corroding the circuit metal wires and component switches, causing unnecessary losses

Abstract

The invention relates to a substrate bonding process and a substrate module to be bonded, wherein a peripheral rubber frame is arranged on the surface of a substrate of the substrate module to be bonded, boxed rubber frames are arranged in the peripheral rubber frame, and the height of the boxed rubber frames is greater than the height of the peripheral rubber frame. The substrate bonding process includes the following steps that the peripheral rubber frame is arranged on the surface of a first substrate, the boxed rubber frames for sealing liquid crystal are arranged in the peripheral rubber frame, and the height of the boxed rubber frames is greater than the height of the peripheral rubber frame; the air between the first substrate and a second substrate is sucked off; the first substrate and the second substrate are preliminarily bonded; gas is filled in between the first substrate and the second substrate; the first substrate and the second substrate are further bonded. The technical scheme of the invention can prevent the liquid crystal in the boxes from impacting the boxed rubber frames to cause penetration, save process time and cost and decrease the probability that circuit wires and element switches are corroded by acid liquid.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate bonding process and a substrate component to be bonded. Background technique [0002] In the manufacturing process of the existing liquid crystal display panel, the array substrate (TFT) and the color filter substrate (CF) need to be bonded together by a sealing glue. According to the different coating positions of the sealant, the sealant is divided into the main sealant for sealing the liquid crystal in the box and the peripheral sealant for maintaining the stability of the gap between the substrates. Such as figure 1 As shown, in the substrate bonding process of the prior art, the peripheral rubber frame 51 formed by the peripheral sealant of the substrate is usually arranged on the surface of the first substrate 50, and the box formed by the main sealant is arranged inside the peripheral rubber frame 51. Plastic frame 52; make the first substrate 51 and the sec...
