Method of data display through the vehicle windscreen and device for its implementation
First Claim
1. A method of operating a data display device to project visual data to a driver, the data display device including a compact body, at least two optical systems including a virtual image display system and a real image display system, a controller, and a speed sensor of a vehicle, wherein the controller, one or more elements of the virtual image display system, and one or more elements of the real image display system are contained within the compact body, the method comprising:
- obtaining, by the controller, a speed value from the speed sensor;
controlling, by the controller, the virtual image display system to be turned on and the real image display system to be turned off when the obtained speed value is greater than or equal to a first threshold value;
causing, by the controller, display of virtual images of first content on a windscreen of the vehicle using the virtual image display system when the virtual image display system is turned on and when the obtained speed value is at or above the first threshold value;
causing, by the controller, display of virtual images of additional first content on the windscreen using the virtual image display system when the virtual image display system is turned on and when the obtained speed value is below the first threshold value;
controlling, by the controller, the real image display system to be turned on and the virtual image display system to be turned off when the obtained speed value is below a second threshold value, wherein the first threshold is greater than the second threshold; and
causing, by the controller, display of real images of second content on the windscreen using the real image display system when the real image display system is turned on and when the obtained speed value is below the second threshold value.

Abstract
Indication systems for the drivers of vehicles and cars include a data display device that combines two optical systems of the image display—the virtual image display system and the real image display system. The display device may be configured to provide a maximum of displayed information and to ensure safe driving, by controlling the level of details and the content of the data displayed for the vehicle driver, depending on the speed, and by choosing the optical system of data display to minimize the accident risk. Image quality and safe driving may be improved due to the combination of two systems and control of the level of detail of displayed data.

7. A data display device, comprising:
-
a speed sensor; a virtual image display system comprising; a coherent light source, illumination optical components, and a first matrix and optical components arranged to generate a virtual image, including a film on a vehicle windscreen, wherein the film comprises at least one of a holographic image, a light-induced grating recorded to work at a certain wavelength and be transparent to other visible spectrum wavelengths, or a color filter that reflects light at a certain wavelength and is transparent to the other wavelengths of a visible spectrum; a real image display system comprising; one or more sources of visible light, illumination optical components, and a second matrix and optical components arranged to generate a real image, including a partially transparent film on the vehicle windscreen, wherein the partially transparent film is arranged to diffusely reflect only a preselected portion of visible light from the visible spectrum; a controller arranged to; obtain a speed value from the speed sensor, control the virtual image display system to be turned on and the real image display system to be turned off when the obtained speed value is greater than or equal to a first threshold value, control the real image display system to be turned on and the virtual image display system to be turned off when the obtained speed value is less than a second threshold value, wherein the second threshold is less than the first threshold, provide first content to be displayed using the virtual image display system when the obtained speed value is above the first threshold value, provide additional first content to be displayed using the virtual image display system when the obtained speed value is below the first threshold value and above the second threshold value, and provide second content to be displayed using the real image display system when the obtained speed value is below the second threshold value; and a compact body containing, within the compact body, the controller, one or more elements of the virtual image display system, and one or more elements of the real image display system. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. At least one non-transitory computer-readable media (NTCRM) comprising instructions, wherein execution of the instructions is to cause a controller of a head-up display (HUD) system in a vehicle to:
-
obtain a speed value from a speed sensor of the vehicle; when the obtained speed value is above a first threshold value, turn on a virtual image display system of the HUD system, turn off a real image display system of the HUD system, and control the virtual image display system to generate and project one or more virtual images of first content onto a first portion of a windshield of the vehicle; when the obtained speed value is below a second threshold value that is less than the first threshold value, turn on the real image display system, turn off the virtual image display system, and control the real image display system to generate and project one or more real images of second content onto a second portion of the windshield; and when the obtained speed value is below the first threshold value and above the second threshold value, control the virtual image display system to generate and project one or more virtual images of additional first content onto the first portion of the windshield, wherein the HUD system comprises a compact housing, wherein the controller, one or more elements of the virtual image display system, and one or more elements of the real image display system are contained within the compact housing. - View Dependent Claims (16, 17, 18, 19)
