Vehicle-mounted bent C-shaped screen fitting method

Abstract

The invention discloses a vehicle-mounted bent C-shaped screen attaching method which comprises the following steps: S1, attaching optical cement to a liquid crystal screen, and then arranging the liquid crystal screen on an upper attaching platform in a vacuum cavity; the bent C-shaped glass cover plate is arranged on a lower attaching platform in the vacuum cavity, and then the bent C-shaped glass cover plate is sucked to be flat; s2, the upper laminating platform is close to the lower laminating platform, so that the liquid crystal screen and the bent C-shaped glass cover plate are subjected to vacuum laminating; s3, the external force applied to the liquid crystal screen and the bent C-shaped glass cover plate is removed, so that the bent C-shaped glass cover plate recovers the bent state; s4, after the above steps, the liquid crystal screen and the bent C-shaped glass cover plate are jointly assembled into a full-lamination assembly; and S5, the full-lamination assembly and a backlight module are assembled. The method is reasonable in step design, curved surface fitting is converted into plane fitting, and therefore the production yield and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of a vehicle-mounted curved C-shaped screen, in particular to a bonding method of a vehicle-mounted curved C-shaped screen. Background technique [0002] Background: With the development of in-vehicle display technology, the application of the display screen is becoming more and more extensive. In order to improve the customer experience, the requirements for the shape of the display screen have been continuously improved. Not only large size and multiple screens, but also the development of curved C-shaped screens. It will be a mainstream trend and standard on high-end models. It is a difficult problem to fully fit the curved C-type screen. Traditionally, the COVER LENS (ie glass cover) is maintained in the curved state for lamination, and a concave-convex profiling mold is required. See figure 2 , the concave profiling die is the upper profiling die (8), and the convex profiling die is the lower profiling...

AI Technical Summary

Problems solved by technology

[0014] Full lamination of large-size curved C-shaped screens in vehicles is still in its infancy in the industry, and there is no mature solution. If the curved surface lamination process is used, there will be more unknowns, which will affect the process yield and product quality.
