Abstract

The invention relates to the technical field of glass products, in particular to automobile glass installed at an opening of an automobile body, and particularly provides a windshield with improved local optical quality and a manufacturing method thereof. The windshield comprises an outer glass plate, an inner glass plate and a middle bonding layer, an opaque shielding layer is arranged on the second surface and / or the fourth surface, and at least one optical transmission area is arranged in the opaque shielding layer. The opaque shielding layer is formed by carrying out high-temperature heattreatment and bending forming on a dark ink layer printed on a straight glass plate at the temperature of at least 560 DEG C, and the optical transmission area is formed by removing a local area of the dark ink layer on the bent glass plate. According to the invention, the defects of optical distortion and the like possibly generated in the opaque shielding layer can be avoided, an image acquisition device can acquire images conveniently, the images are clearer, the recognition degree is higher, the driving safety is improved, and glass accessories such as a camera bracket, a rain sensor bracket and the like are also easy to bond and fix.

Description

Technical field: [0001] The invention relates to the technical field of glass products, in particular to the automobile glass installed at the opening of the automobile body, and specifically provides a windshield with improved local optical quality and a manufacturing method thereof. Background technique: [0002] Due to the popularization of automotive intelligent technologies such as assisted driving and automatic driving, the demand for the number of cameras has also grown from installing only one camera to installing two, three or even more, and the requirements for the image quality of the cameras have also increased significantly . For the front view camera assembly (FCM) installed on the windshield of the car, the camera needs to obtain the real-time view of the car in the direction of travel through the windshield of the car, which requires the windshield of the car to be used for camera observation The optical transmission area outside the car has higher requireme...
