一种汽车用车载抬头显示设备 An automotive display device with on-board rise

技术领域 FIELD

[0001] 本发明涉及汽车辅助设备技术领域,特别涉及一种汽车用车载抬头显示设备。 [0001] The present invention relates to the field of assistive technology automotive equipment, and particularly relates to an automotive vehicle display device rise.

背景技术 Background technique

[0002] 抬头显示设备(HUD),最早应用于军用航空领域,为了避免飞行员在驾驶中低头看仪表盘这个动作,将重要的信息及参数,显示在飞行员的视场前方,这样可以在不改变飞行员视场的情况下,直接观察飞机的重要参数信息。 [0002] heads-up display device (HUD), was first used in military aviation, in order to avoid the pilot to look down at the instrument panel while driving this action, important information and parameters, appear in front of the pilot's field of view, this can not be changed the case of pilots field of view, the important parameter information direct observation aircraft.

[0003] 抬头显示设备现在也广泛应用于商用航空、汽车、电视、电脑游戏等领域。 [0003] heads-up display devices are now widely used in commercial aviation, automobiles, television, computer games and so on. 本发明主要针对于汽车领域。 The present invention is primarily directed to the automotive sector. 现有的抬头显示设备主要基于以下三种技术:0LED、DLP、基于光反射原理的显示技术。 Conventional head-up display device based on the following three technologies: 0LED, DLP, based on the principle of light reflection display technology. 该三种技术存在如下问题: There is the problem of the three technologies:

[0004] (I) OLED (有机发光二极管)技术其优点是可自发光,在白天黑夜均能清晰显示,其缺点是:使用寿命不长,技术还不是很成熟,成本较高,并且只能显示有限预设字符和简单图形,无法使用字库,不能显示复杂图形信息,无法形成大范围的商业应用。 [0004] (I) OLED (Organic Light Emitting Diode) technology has the advantage that self-emit light, can clearly show the day and night, the drawback is: life is not long, is not very mature technology, high cost, and the only limited pre-show characters and simple graphics, fonts can not be used, you can not display complex graphics information and can not form a wide range of commercial applications.

[0005] (2)DLP (数字光处理)技术比较成熟,而且成像及色彩倶佳,其缺点是:功耗、体积都很大,造价昂贵,不适合车载或者小型化的终端设备应用,现有大多数小型DLP投影装置投影亮度较低,在白天或强光条件下几乎无法看清,极大地限制的抬头显示技术在汽车上的应用。 [0005] (2) DLP (Digital Light Processing) technology is relatively mature, and good imaging and color Ju, which disadvantages are: power, volume are large, expensive, or not suitable for miniaturization of the vehicle-mounted terminal device applications, conventional most small projection means DLP projectors low luminance, almost impossible to see in daylight or bright light conditions, the application of technology in the automotive head-up display is greatly limited.

[0006] (3)基于光反射原理的显示技术主要是一些服务类软件厂商在移动手机终端软件中增加了抬头显示显示模式,将手机放在汽车的前挡风玻璃下方,就可以将内容投影,其最大的缺陷就是白天因为外界光强太强或者外界光从车后方或侧方射入,显示内容几乎不能看清,基本上只能在夜间或弱光条件下使用。 [0006] (3) display technology based on the principle of light reflection mainly some service class software vendors increase to the rise in mobile handset software display mode, place the phone under the front windshield of the car, you can project contents , which is the greatest defect daytime ambient light intensity is too strong or because of external light incident from the rear or side of the vehicle, the display content can hardly see, basically only used at night or in low light conditions. 为了解决显示不清的问题,一些厂商通过在前挡风玻璃加贴专用抬头显示反射膜以提升显示效果,由于放射膜位置固定,司机在驾车过程中必须保持固定坐姿和座位高度才能看清现实内容。 In order to solve the problem of unclear, some manufacturers dedicated affixed by the rise of the front windshield display reflective film to enhance the display effect, due to the radiation film fixed position, the driver must maintain a fixed posture and seat height while driving in order to see the reality content. 由于反射膜是粘贴在前挡风玻璃上,在不需要使用抬头显示设备时,反射膜无法方便移除,非常影响美观。 Since the reflective film is pasted on the front windshield, when not using the head-up display device, a reflective film can not be removed easily, very aesthetic impact. 另外反射膜只能按一定反射率反射图像,无法根据光强调节显示对比度,使用体验较差。 Further reflection film reflecting only a certain reflectance image can not be displayed according to the light intensity adjustment contrast, experience poor.
