Abstract

In a light source device, a row of fibers is provided in which a plurality of optical fibers is arrayed in a single row in parallel fashion separately from each other. A light-direction controller is disposed on one side of the optical fibers, main fibers is disposed above and below the light-direction controller, and a main fiber is disposed at the other end of the row of fibers. Light sources are connected to each of the end portions of the main fibers. Three types of mirrors that mutually differ in direction are formed on the surface of the light-direction controller, light emitted from a main fiber enters the optical fibers by way of a first mirror, and light emitted from a main fiber enters the optical fibers by way of a second mirror.

Claims (20)

1. A method for driving a display device, comprising:

a step for lighting a first light source and turning off other light sources to illuminate a first row of pixels of a liquid crystal panel and setting in a prescribed direction the orientation of liquid crystal molecules in said first row of pixels; and

a step for lighting a second light source and turning off other light sources to illuminate a second row of pixels of a liquid crystal panel and setting in a prescribed direction the orientation of liquid crystal molecules in said second row of pixels.

2. The method for driving a display device according to claim 1 , wherein

said first light source emits light of a first color, and said first row of pixels is a row of pixels for displaying an image that corresponds to said first color; and

said second light source emits light of a second color that is different than said first color, and said second row of pixels is a row of pixels for displaying an image that corresponds to said second color.

3. A method for driving a display device, comprising:

a first image display step for allowing light to enter one end of optical fibers, emitting in a first direction said light from light-emitting portions arrayed along a lengthwise direction of the optical fibers, and displaying a first image on a liquid crystal panel illuminated by the light; and

a second image display step for allowing light to enter the other end of said optical fibers, emitting in a second direction said light from said light-emitting portions, and displaying a second image on said liquid crystal panel.

4. The method for driving a display device according claim 3 , wherein

said first image is an image for the right eye; and

said second image is an image for the left eye.

5. The method for driving a display device according to claim 3 , wherein each of said first image display step and said second image display steps comprises:

a step for lighting a first light source and turning off other light sources to illuminate a first row of pixels of a liquid crystal panel and setting in a prescribed direction the orientation of liquid crystal molecules in said first row of pixels; and

a step for lighting a second light source and turning off other light sources to illuminate a second row of pixels of a liquid crystal panel and setting in a prescribed direction the orientation of liquid crystal molecules in said second row of pixels.

6. The method for driving a display device according claim 5 , wherein

said first light source emits light of a first color;

said first row of pixels is a row of pixels for displaying an image that corresponds to said first color;

said second light source emits light of a second color that is different than said first color; and

said second row of pixels is a row of pixels for displaying an image that corresponds to said second color.
