DISPLAY DEVICE FOR VEHICLE

摘要

Provided is a display device for a vehicle that can, in a configuration in which the cost of parts is curbed, quickly raise the temperature of a laser light source (LD) in a low temperature environment, and quickly perform stable image output. The LDs (11, 12, 13) emit laser light (RGB) and an MEMS mirror (30) scans the laser light (RGB) and generates a display image (M). A convex mirror (70) reflects display light (L) indicating the display image (M) in an external direction via a translucent light-transmitting unit (90). An LD driving means (101) emits laser light (RGB) to the LDs (11, 12, 13) when the temperature is low, and causes the LDs (11, 12, 13) to perform self-heating driving for raising the temperature of themselves.

主权项

1. A display device for a vehicle comprising:
a housing configured to have a light-transmitting unit for transmitting light; a laser light source for emitting laser light; light source driving means for driving the laser light source; a scanning unit for generating an image by scanning the laser light; scanning unit driving means for driving the scanning unit; and reflection means for reflecting display light indicating the image in a direction of the light-transmitting unit, wherein the light source driving means emits the laser light to the laser light source and performs a self-heating drive to raise the temperature of the laser light source.
