Abstract
An adaptive adjustment system and method for the brightness of a holographic waveguide display device is provided. The adaptive adjustment system includes five functional modules: a computer control module, a driving and adjustment module, a micro image source display module, an optical waveguide transmission module and an ambient light acquisition module. A video signal is provided by the computer control module and is then transmitted under the control of the driving and adjustment module to illuminate the micro image source display module, and light information of the micro image source display module is finally transmitted to human eyes by means of the optical waveguide transmission module to realize display. The ambient light acquisition module is used for acquiring environmental illuminance information and transmitting the environmental illuminance information to the driving and adjustment module to change the brightness of the micro image source display module.
