Abstract
A LCD luminous structure comprises a LCD liquid crystal displaying plate which is connected with a circuit by a bus, a light guiding plate, a dispersing piece, etc., light emitting diodes or other light sources are installed on the sides of the light guiding plate. Wherein the luminous piece having the function of luminosity is installed on the bottom of the liquid crystal displaying plate. By above structure, the power may be saved and the cell need not be updated frequently.
Claims1
A luminous structure for liquid crystal displays, comprising:
- a circuit board;
- a liquid crystal display electrically coupled to said circuit board;
- a luminous piece disposed beneath said liquid crystal display for absorbing ambient light impinging thereon and subsequently radiating light to function as a backlight for said liquid crystal display;
- a dispersing plate disposed beneath said luminous piece;
- a light guiding plate disposed beneath said dispersing plate and having an upper face disposed contiguous a lower face of said dispersing plate;
- and,
- at least one light source coupled to said circuit beard, said light source being selectably operable to provide light directed toward a side edge of said light guiding plate, said light guiding plate guiding incident light from said light source to be emitted from said upper face thereof for supplying light to said luminous piece and said liquid crystal display through said dispersing plate and thereby supplement radiated light from said luminous piece.
