AI Technical Summary
Traditional black dammed adhesive is prone to causing liquid optical adhesive to overflow, affecting the display effect, especially in narrow-bezel products, which reduces the product's market competitiveness.
A transparent damming adhesive is used instead of a black damming adhesive. The transparent damming adhesive is compatible with liquid optical adhesives and uses a high-viscosity two-component addition-type silicone gel. It can activate the reaction and cure quickly under UV light. It has low shrinkage and high adhesion performance and is suitable for bonding and sealing optically transparent parts.
The transparent damming adhesive and liquid optical adhesive are perfectly integrated without affecting the display effect, improving product yield and market competitiveness, reducing costs and increasing production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to vehicle display screen and instrument screen technical field, concretely is a transparent dam glue optical laminating structure. BACKGROUND
[0002] With the development of automobile intelligence and networking, the demand for vehicle display screens is increasing. Optical laminating technology not only improves the display effect and user experience of display screens, but also promotes their popularity in mid-to-high-end vehicles. With the advancement of technology and the reduction of costs, optical laminating technology is expected to be more widely used in mid-to-low-end vehicles in the future. At the same time, in order to meet the increasingly high quality requirements of users for display screens, optical laminating technology has become an important part of the display screen production process. Traditional frame bonding technology is gradually being eliminated, and more advanced optical full-laminating technology is taking its place. Optical full-laminating technology completely and seamlessly laminates the display screen and touch screen with glue, effectively reducing environmental light reflection, increasing light transmittance, improving image contrast, and reducing dust and moisture intrusion, improving the environmental adaptability and reliability of the screen.
[0003] For vehicle central control screens and instrument screens, whether single or double screens, they are basically below 15 inches, and point bonding technology is used for optical lamination. Before applying optical glue, a dam glue is first applied around the touch screen by automated equipment before applying liquid optical glue. This dam glue is a high-viscosity two-component addition type silicone gel, which is suitable for bonding and sealing of optical transparent components, especially touch display screen modules. Traditional dam glue is black, and if there is inward overflow of glue, the liquid optical glue will come into contact with the black dam glue, causing the end user to be able to see the black dam glue at a certain viewing angle, affecting the display effect and causing strong complaints from users. Especially for narrow-bezel products, the inward overflow of black dam glue is easily visible to end users, affecting the display effect and causing customer complaints, reducing the product's market competitiveness.
