A head-up display front windshield

Abstract

The present invention relates to the technical field of head-up display, more particularly to a head-up display system on vehicles, particularly to a head-up display front windshield capable of being used in a head-up display system. The head-up display front windshield comprises an inner glass plate, an outer glass plate, and a middle diaphragm sandwiched between the inner glass plate and the outer glass plate, and further comprises a transparent nanometer film and a low surface energy film layer, wherein the transparent nanometer film comprises at least a high refractive index layer / low refractive index layer laminating structure sequentially deposited from the inner glass plate surface to the outside. According to the present invention, with the head-up display front windshield, it can be ensured that fingerprints or other dirt are difficultly stained on the inner surface of the front windshield so as to maintain the cleaning inner surface of the inner glass plate; and in the case of assurance of the unchanged reflectivity of the P-polarized light, the substantially unchanged front windshield spectrum and the substantially unchanged color characteristics, the yellow component under the high angle reflection condition is significantly reduced so as to obtain the beautiful blue reflective light.

Description

Technical field: [0001] The present invention relates to the field of head-up display technology, in particular to a head-up display system on a car, in particular to a head-up display front windshield that can be used in the head-up display system. Background technique: [0002] With the development of science and technology, head-up display (HUD, Head Up Display) systems are increasingly used in automobiles. The head-up display system on the car can display important driving information, such as speed, engine speed, fuel consumption, tire pressure, navigation and information of external smart devices in the driver's field of vision on the front windshield in real time, so that driving The driver can see the driving information without bowing his head, so as to avoid distracting the road ahead; at the same time, the driver does not have to adjust his eyes between observing the distant road and the nearby instrument, which can avoid eye fatigue and greatly improve the Enhan...
