1. A composite display device, comprising:
a composite display, comprising:
a first display panel; and
a second display panel disposed on and aligned with the first display panel;
a brightness acquisition module connected to the composite display and configured to acquire an ambient brightness around the composite display;
an image management module connected to the brightness acquisition module, wherein the image management module generates a first image setting signal corresponding to the first display panel according to the ambient brightness, and generates a second image setting signal corresponding to the second display panel according to the first image setting signal; and
a panel controlling module connected to the image management module and the composite display, wherein the panel controlling module controls the first display panel to display a first image based on the first image setting signal, and controls the second display panel to display a second image based on the second image setting signal;
wherein the first image overlaps with the second image to form a composite image;
wherein the first image setting signal comprises a transmission spectrum data, the image management module acquires a first transmittance segment corresponding to a red spectrum, a second transmittance segment corresponding to a green spectrum and a third transmittance segment corresponding to a blue spectrum from the transmission spectrum data, and the image management module respectively adjusts a first intensity parameter corresponding to the red spectrum, a second intensity parameter corresponding to the green spectrum and a third intensity parameter corresponding to the blue spectrum in the second image setting signal according to the first transmittance segment, the second transmittance segment and the third transmittance segment.
