Abstract
Description
The present invention relates to a display device, and more particularly to a vehicle head-up display device.
In the 21st century, when we look at human living spaces, we can roughly divide them into three categories: home, workplace, and moving space. In particular, the vehicle occupies most of the moving space. Thus, as time in a vehicle increases, electronic products used in residential spaces are being developed to be used in a vehicle. For example, an audio video system, a simple refrigerator, etc. can be mentioned.
In addition, as electronic products are developed, they are applied to fields that help driving. A typical example is car navigation. However, the driver must check the objects in the field of view and drive while checking the driving state (speed, RPM, direction, etc.) of the vehicle.
Therefore, there are several systems that are currently being developed as a medium that provides the driver's safety and effectively transmits vehicle driving information and surrounding information to the driver. Among them, the head up display (hereinafter, abbreviated as 'HUD') is the main. It is becoming a concern.
An object of the present invention is to provide a head-up display device for a vehicle that can protect the display element from sunlight flowing into the vehicle.
According to an aspect of the present invention, there is provided a vehicle head-up display device including: a display device configured to display driving image information of a vehicle; A mirror for reflecting and projecting driving image information displayed on the display device to a driver to implement a virtual image; An adjusting unit for adjusting a light reflection angle of the mirror; And a controller configured to adjust the reflection angle of the mirror by controlling the controller so that external sunlight is not reflected to the display element by the mirror.
In this case, the mirror may be an aspherical combiner.
In addition, the control unit, and the rotation axis coupled to the central axis of the mirror; And a rotating motor coupled to the rotating shaft and rotating the mirror at a predetermined angle about the rotating shaft under the control of the controller.
The controller may control the controller to prevent external sunlight from being reflected by the mirror to the display device when the display device is not driven.
In addition, the head-up display device for a vehicle according to the present invention may further comprise a temperature measuring unit for measuring the temperature of the display element.
That is, when the temperature of the display element measured by the temperature measuring unit is out of a preset temperature range, the controller may control the adjusting unit such that the external sunlight is not reflected to the display element by the mirror.
In addition, when the temperature of the display element measured by the temperature measuring unit is out of a predetermined temperature range, the controller may not drive the display element until the temperature of the display element is within the temperature range.
In addition, the controller may not drive the display element for a preset time when the temperature of the display element measured by the temperature measuring unit is out of a preset temperature range.
In addition, when the temperature of the display element measured by the temperature measuring unit is out of a preset temperature range, the controller lowers the display brightness of the display element to a preset level until the temperature of the display element is within the temperature range. Can be.
The controller may lower the display brightness of the display element to a predetermined level for a preset time when the temperature of the display element measured by the temperature measuring unit is out of a preset temperature range.
The head-up display device for a vehicle according to the present invention has an effect of protecting the display element from the heat of sunlight by adjusting the light reflection angle of the mirror so that external sunlight does not reversely enter the display element by the mirror.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used for the same reference numerals even though they are shown in different drawings.
In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
