Embodiment 1

[0019] Such as figure 1 As shown, it represents a car navigation display device 100 provided by the present invention. The car navigation display device 100 includes a photochromic layer 1 and a laser emitting device 2, the photochromic layer 1 is arranged on the vehicle, and the laser emitting device 2 is configured to generate corresponding laser light according to the navigation information and irradiate the The photochromic layer 1 makes the photochromic layer 1 change color to display navigation information.

[0020] In this way, the car navigation display device 100 provided in this embodiment utilizes the feature that the photochromic compound can change color repeatedly when it is irradiated by light of different intensities and wavelengths. The photochromic layer 1 makes the photochromic layer 1 change color to display navigation information, which can realize fast writing and erasing of navigation information. In this way, since the navigation information is display...

Embodiment 2

[0024] This embodiment provides a vehicle navigation display method, including: acquiring navigation information, generating corresponding laser light according to the navigation information, and irradiating the laser light on a photochromic layer so that the photochromic layer changes color to display the navigation information. Specifically, the navigation device can obtain navigation information and transmit the navigation information to the laser emitting device, and the laser emitting device can generate corresponding laser light and irradiate the photochromic layer so that the photochromic layer changes color to display the navigation information. Specifically, the photochromic layer can be a WO3 thin film, and the laser emitting device can include a KrF excimer laser and a Nd:YAG laser, and the KrF excimer laser is configured to emit a 248nm laser to irradiate the The photochromic layer makes the photochromic layer produce color images to display navigation information, ...

Abstract

The invention provides a vehicle-mounted navigation display device and method. The device comprises a photochromic layer and a laser emission device, wherein the photochromic layer is arranged on a vehicle, and the laser emission device is configured to generate corresponding laser light according to navigation information and irradiate the photochromic layer to change the color of the photochromic layer so as to display the navigation information. According to the vehicle-mounted navigation display device and the vehicle-mounted navigation display method, by utilizing the characteristics thatthe color of a photochromic compound can be repeatedly and circularly changed when the photochromic compound is irradiated by light with different intensity and wavelengths, the photochromic layer isarranged on the vehicle, the laser emission device is utilized for irradiating the photochromic layer to change the color of the photochromic layer so as to display the navigation information, and the navigation information can be rapidly written and erased and is displayed through the color change of the photochromic layer, so that the navigation information is clearly displayed; and the photochromic layer can be arranged on the surfaces of a vehicle center console or glass and the like, so that the distribution space of the vehicle can be effectively utilized, and convenience is provided for a driver in observation.

Description

technical field [0001] The invention relates to a vehicle display technology, in particular to a vehicle navigation display device and method. Background technique [0002] Now, with the continuous upgrading and complexity of urban road network construction, car navigation devices have become a must-have item for many vehicles. The configuration of navigation devices can be used to view information such as routes and road conditions, which facilitates travel and improves efficiency. Existing vehicles generally display navigation information through the display screen, but due to the internal layout of the vehicle, the installation position and installation size of the display screen are limited, which often makes the display of navigation information inconvenient for the driver to view; there are also projection methods The technical solution for displaying navigation information can effectively utilize the vehicle layout space, but the navigation information displayed by pr...
