Abstract

The invention discloses a scanning driver, an optical fiber scanning device and projection display equipment; the scanning driver comprises a first actuating part as a slow axis and a second actuatingpart as a fast axis; the first actuating part can drive the second actuating part to vibrate in a first direction, and the second actuating part can vibrate in a second direction; the second actuating part comprises a base body and a piezoelectric driving piece, and the base body comprises a first surface and a second surface which are oppositely arranged; the piezoelectric driving piece includea first piezoelectric driving sheet disposed on the first surface and a second piezoelectric driving sheet disposed on the second surface. According to the scheme, a novel scanning driver structure isprovided, the structure is particularly suitable for achieving grid type scanning and control, and therefore compared with a spiral scanner, the scanning driver structure has the advantages of beingeasy to match with a rectangular video and high in pixel utilization rate.

Description

technical field [0001] The invention relates to the field of scanning imaging, in particular to a scanning driver, an optical fiber scanning device and projection display equipment. Background technique [0002] The fiber optic scanner can scan according to the designer's pre-designed trajectory to output images, thereby replacing traditional LCD (Liquid Crystal Display; liquid crystal display), LCOS (Liquid Crystal on Silicon; liquid crystal with silicon / silicon-based liquid crystal) and OLED (Organic Light-Emitting Diode; Organic Light-Emitting Diode) image source, etc., integrated into HMD (Head Mount Display; head-mounted display), micro projection equipment and vehicle HUD (Head Up Display; head-up display) and other equipment, and can also Used in medical endoscopes, scanning tunneling microscopes and other equipment, the application range is very wide. [0003] At present, the main application fields of fiber optic scanners are endoscopes. The working principle of th...
