Title:
HEAD-UP DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/129186
Kind Code:
A1
Abstract:
Provided is a head-up display device with which it is possible to display an image easily recognized by a user. A display 20 for a display mechanism 100 in the head-up display device includes: a light source unit 206 capable of generating light that is the origin of a scanning line; a scan unit 205 for scanning light in a first direction and in a second direction using a first scan element and a second scan element, respectively; a processing unit 201 for generating a first drive signal having a frequency that matches the resonance frequency of the first scan element 205H; and a drive unit 204 for executing a resonance mode that is based on the first drive signal. The processing unit 201 generates a second drive signal having a variable display waveform (TII) that is dependent on the resonance frequency, fixed first non-display waveforms (TI, TIV, TVI) that are not dependent on the resonance frequency, and a variable second non-display waveform (TIII) that is dependent on the resonance frequency. The drive unit 204 drives the second scan element 205V in a non-resonance mode that is based on the second drive signal.
