  • Patent number: 11847980
    Abstract: Provided is a head-up display apparatus capable of preventing damage due to sunlight and ensuring user convenience. A reflection mirror M1 reflects an image created by a display panel and projects it onto a display region. A solar radiation sensor detects a sunlight intensity when a position of sun exists within a predetermined detection range. A blocking mechanism forms a projected light path of an image between the display region and the display panel when being turned off, and blocks the projected light path of the image and an incident light path of the sunlight which is direction opposite thereto when being turned on. A protection processor controls ON/OFF of the blocking mechanism based on an estimated temperature of the display panel, which is estimated by using a sunlight intensity from the solar radiation sensor, luminance of a light source, and an ambient temperature.
