Optical module and head-up display

The invention discloses an optical module and a head-up display, and relates to the technical field of optics. The optical module comprises an image generation unit and a reflector group which are arranged in sequence; the image generation unit comprises a light source and a display unit located on the light emitting side of the light source, light beams emitted by the light source pass through the display unit and then output image signals, and the image signals are reflected to a front windshield of an automobile through the reflector group and are imaged on the front windshield; a reflective first polarizing film is arranged between the light source and the display unit, and the first polarizing film is used for reflecting part of light beams emitted by the light source. The head-up display comprises the optical module. The optical module and the head-up display can reduce the temperature of the display unit. 一种光学模组及抬头显示器，涉及光学技术领域。该光学模组包括依次设置的图像生成单元、反射镜组；图像生成单元包括光源和位于光源出光侧的显示单元，光源出射的光束通过显示单元后输出图像信号，图像信号经反射
