The invention relates to the technical field of head-up display, in particular to a dustproof plate and a head-up display. The dustproof plate comprises a first surface and a second surface which are opposite, the first surface is provided with a plurality of shielding grooves extending in the first direction, the shielding grooves are arranged in an array mode in the second direction, the first direction is perpendicular to the second direction, and each shielding groove is provided with a first side face and a second side face which are opposite in the second direction; wherein the first side face of any shielding groove is used for reflecting light rays entering the first side face to the second side face of the shielding groove, and the second side face is used for absorbing the light rays projected to the second side face. The dustproof plate can restrain stray light from being formed, and the display effect of the head-up display is improved.
本公开涉及抬头显示技术领域,具体而言,涉及一种防尘板及抬头显示器。防尘板包括相对的第一表面与第二表面,第一表面上设有多个沿第一方向延伸的屏蔽槽,屏蔽槽沿第二方向阵列排布,第一方向与第二方向垂直,屏蔽槽具有在第二方向相对的第一侧面与第二侧面;其中,任一屏蔽槽的第一侧面用于将入射该第一侧面的光线反射至该屏蔽槽的第二侧面,第二侧面用于吸收投射至第二侧面的光线。本公开的防尘板可以抑制杂散光的形成,提高抬头显示器的显示效果。
