The invention provides a curved-surface image display system and a vehicle head-up display system thereof. The curved-surface image display system comprises a curved-surface image source, at least one free-form mirror and a transparent substrate. The curved image source emits image light including image information. The free-form mirror is located on an optical path of the image light and reflects the image light to form light to be imaged. The transparent substrate is located on an optical path of the to-be-imaged light and reflects the to-be-imaged light to generate a virtual image. The defects of picture color spots, blurring, image deformation and long-time watching discomfort can be eliminated by utilizing a curved surface image source and matching with aberration distribution of precise calculation; in the backlight design, due to the curved surface image source, the system is close to the ideal light distribution design of the limited angle and position invariant, so that the problems of poor image grade, low contrast ratio and the like are solved.
本申请提供一种曲面影像显示系统及其车用抬头显示系统,曲面影像显示系统包括曲面影像源、至少一个自由曲面镜与透明基板。曲面影像源发射包括影像信息的影像光。自由曲面镜位于影像光的光学路径上,自由曲面镜反射影像光,以形成待成像光。透明基板位于待成像光的光学路径上,透明基板反射待成像光,以产生虚像。利用曲面影像源,配合精密计算的像差分配,可消除画面彩斑、模糊、影像变形,与长久观看不适的缺点;背光设计因曲面影像源,使其系统趋近于理想的限定角度与位置不变量(Position invariant)的配光设计,进而改善画面品位不良、对比度低等问题。
