摘要:
The present invention relates to a manufacturing method of a display apparatus having a display portion that is made of dot-like reflection portions. The method comprising steps of: heating at least one of a blade portion of a machining tool and a light guide plate, descending the machining tool along a specific formation direction of the blade portion all through this descending step to press the blade portion into a back surface of the light guide plate, ascending the machining tool along a specific formation direction of the blade portion all through this ascending step to pull out the blade portion from the light guide plate, moving the machining tool horizontally, and arranging at least one light source along at least one edge face of the light guide plate. The steps of descending, ascending, and horizontally moving the machining tool are performed repeatedly to form the dot-like reflection portions.

A method of manufacturing a display apparatus that includes: a light guide plate; and a light source provided on an edge face of the light guide plate. In the light guide plate, a display portion made of a dot-like reflection portion with a reflection surface for reflecting a light beam emitted from the light source to a surface is formed. In the display portion, the reflected light beam from the dot-like reflection portion is configured to be visible. This display apparatus manufactured by the method is excellent in transparency, has a display portion visually recognizable with ease, and can be manufactured at a low cost.

In the present invention, a deformation process is applied to a part of an image fiber, and when implementing improvement of the quality of the transmitted image, the improvement of the image quality in the center region and peripheral region of the image fiber in the radial direction is carried out to an equal degree, and a uniform improvement of the entire screen can be carried out. A processed part is formed having a deformation of all cores that is substantially identical by deforming in the radial direction or by deforming and twisting a part of an image fiber having a plurality of cores that function as pixels in the radial direction thereof. The image fiber can be manufactured by a processing in which by a part of the image fiber having a plurality of cores that function as pixels is heated, and deformed in the radial direction thereof or simultaneously deformed and twisted in the radial direction thereof this heated part.

A display apparatus includes a transparent light guide plate, a light source provided on at least one end surface of the light guide plate, and a mask provided on a front surface of the light guide plate. The light guide plate is formed of a plurality of reflecting and scattering portions having reflecting and scattering surfaces that reflect a light emitted from the light source and emit the reflected light from a front surface side. The mask allows an observer to visually recognize the light reflected from a reflective portion for the right eye, using the right eye, and the light reflected from a reflective portion for the left eye, using the left eye, whereby the reflected light beams can be stereoscopically recognized due to binocular parallax.

The illumination device is provided with a plurality of light guide bodies, the bottom face of which is given light reflection/scattering treatment, light sources individually connected to the end portions of a plurality of the light guide bodies to radiate the bottom faces of a plurality of the light guide bodies, and a control unit for changing the intensity of light made incident from the light sources to a plurality of the light guide bodies. A plurality of the light guide bodies are laminated so as to be at least partially overlapped at the respective light emitting regions of the light guide bodies, and the control unit allows the intensity of light made incident from the light sources to the light guide bodies to change with the lapse of time.
