The present invention is based on the principle of liquid crystal display, in described backlight module 30 the place aheads, set gradually described the first display panels 10 and described the second display panels 20; Wherein, described the first display panels 10 can be for carrying out conventional image demonstration, and described the second display panels 20 can be for optionally seeing through the demonstration image of described the first display panels 10.On this basis, by respectively the demonstration image of described the first display panels 10 and described the second display panels 20 being processed, and realize simultaneous display, just can make the user who faces the user of described the first display panels 10 and face described the second display panels 20 watch different pictures.
For example, in the situation that described the first display panels 10 carries out routine demonstration, can pass through described the second display panels 20 on-load voltages, make it be shown as " black image ", thereby make the demonstration image of described the first display panels 10 cannot see through described the second display panels 20; Or also can, by described the second display panels 20 on-load voltage not, make it be shown as " white image ", thereby make the demonstration image of described the first display panels 10 can see through described the second display panels 20.
Here, described " black image " and described " white image " is aimed at the light transmission of described display panels, described " black image " refers to that described display panels is light tight, and described " white image " refers to described display panels light-permeable.
Certainly, except making described the second display panels 20 be shown as " black image " or " white image ", can also make it be shown as according to actual needs other specific image.
On this basis, can, by the demonstration image of described the first display panels 10 is processed, make it be shown as two continuous two field pictures; Be image A and image B; Because the refreshing frequency of image is very high, can be 120Hz conventionally, the mistiming between this two two field picture of human eye None-identified, the image of therefore watching in the face of the user of described the first display panels 10 is the combination image of A+B.Meanwhile, by the demonstration image of described the second display panels 20 is processed, make it be shown as two continuous two field pictures, i.e. " black image " and " white image "; By the demonstration image of described the first display panels 10 and described the second display panels 20 is synchronously processed, just can be when described the first display panels 10 shows image A, make described the second display panels 20 show " black image ", when described the first display panels 10 shows image B, make described the second display panels 20 show " white image "; Like this, the image A that described the first display panels 10 is shown due to described " black image " cannot see through described the second display panels 20, and the image B that described " white image " shows described the first display panels 10 can see through described the second display panels 20, the image of therefore watching in the face of the user of described the second display panels 20 is only image B.
Example, the image A showing when described the first display panels 10 and image B as shown in Fig. 2 (a), as described in the second display panels 20 " black image " and " white image " that show as shown in Fig. 2 (b) time, the picture of watching in the face of the user of described the first display panels 10 is the picture shown in right figure in Fig. 2 (c), and the picture of watching in the face of the user of described the second display panels 20 is the picture shown in left figure in Fig. 2 (c).
Known based on foregoing description, being positioned at the picture that the user of diverse location watches may be different; Wherein, the complete image that can watch described the first display panels 10 to show in the face of the user of described the first display panels 10, and only can watch the Overlay of the demonstration image of described the first display panels 10 and the demonstration image of described the second display panels 20 in the face of the user of described the second display panels 20.
