Claims46
A display device comprising:
- a display member including a first plate and a second plate and a displaying material positioned between and supported by said plates, said first plate being light transmissive;
- a light guiding member which faces and extends in parallel with the display member, said light guiding member facing said first plate;
- and
- a light source which illuminates a side end of the first plate and a side end of the light guiding member, so that light transmitted by multiple internal reflections along the inside of each of the first plate and the light guiding member illuminates the displaying material.
A display device comprising:
- a display member which includes a first plate and a second plate and a displaying material positioned between and supported by said plates, said first plate being light transmissive;
- a light guiding member which faces and extends in parallel with the display member, said light guiding member facing said first plate;
- and
- a light source which illuminates a side end of the display member and a side end of the light guiding member, so that light transmitted by multiple internal reflections along the inside of each of the first plate, the second plate and the light guiding member illuminates the displaying material.
An appliance having a display window through which information concerning the operation of said appliance can be displayed, said appliance comprising:
- a display member, provided adjacent to said display window, including a first plate and a second plate and a displaying material positioned between and supported by said plates, said first plate being light transmissive;
- a light guiding member which faces and extends in parallel with the display member, said light guiding member facing said first plate;
