The invention provides a head up display with adjustable backlight. A light sensor is arranged on a display; the light sensor acquires light strength of the environment, brightness of a backlight lamp is automatically adjusted according to a light strength signal from the light sensor by a central processor, and brightness of an image source screen itself can be adjusted. Initial setting of the brightness of the image source screen itself can enable a driver to freely select the habitual image brightness, and automatic backlight adjustment enables the displayed image to adapt to different light environments. According to the head up display, due to the initial setting of the brightness of the image source screen itself, the function of adaptive display backlight adjustment according to environment light can be realized, a virtual image reflected on a projection lens can meet requirements of different drivers, display brightness can also be automatically changed according to environment lights, the displayed virtual image can be seen clearly when the environment light changes, and display effects of the head up display are better.
