Abstract
The utility model discloses a color backlight display screen, which comprises a colorless full-transparent liquid crystal display board, a luminous board and a printed circuit board, wherein, the full-transparent liquid crystal display board is positioned at the outmost side of the backlight display screen; the luminous board and the printed circuit board are arranged inwards in turn. The luminous board comprises a light conducting medium film, a light conducting board, a luminous tube, a light reflecting medium film and a light blocking medium film, wherein, the light conducting medium film is stuck on the upper surface of the light conducting board; the light reflecting medium film is stuck on the lower surface; the luminous tube is fixed at one side of the light conducting board; the light blocking medium film is stuck at the periphery of the light conducting board. The luminous tube can be LEDs of various colors. Chromatic light rays emitted by the LEDs pass through the light conducting board for several times after reflected by the light reflecting medium film and the light blocking medium film, and are finally emitted out via the light conducting medium film; uniform chromatic light rays run through the colorless full-transparent liquid crystal display screen, and present chromatic backlight effect.

Technical field
The utility model relates to a kind of backlight display device of electronic equipment, particularly a kind of colored backlight display screen.
Background technology
The development of advancing by leaps and bounds along with electronic technology, many electrical equipment have all been installed backlit display screen, this backlit display screen is to install light-emitting device below the LCDs of printing opacity, behind the light-emitting device electrified light emitting, light passes LCDs, make display screen present effect backlight, help the user at night or dark place identification displaying contents, handled easily equipment.
This backlit display screen has been applied in the communication and electromechanical equipment of mobile phone etc. widely, triggers the feed circuit of the light-emitting device of backlit display screen again by button, makes it luminous, and then the light that produces passes the printing opacity LCDs, produces effect backlight.
But, existing backlit display screen is few because of the quantity of light-emitting device, and color is single, and the light-conductive media not reason such as science that distributes causes the distribution of light of sending inhomogeneous, makes the irregular phenomenon of brightness of display screen very obvious.Color is simple simultaneously, does not have color effect.
The utility model content
The purpose of this utility model is to provide a kind of colored backlight display screen, and it can use on various electric equipment products, makes electronic product be convenient to operation in dark place, and its illumination effect is good, brightness is even, can send colored light simultaneously.
Colored backlight display screen of the present utility model comprises colourless full impregnated LCD panel, luminous plaque and printed circuit board (PCB), and described full impregnated LCD panel is positioned at the outermost of this backlit display screen, and what inwardly be provided with successively is luminous plaque and printed circuit board (PCB).
This above-mentioned luminous plaque comprises light-conductive media film, light guide plate, luminotron, reflective medium film and the deielectric-coating that is in the light, the upper surface of light guide plate attaches the light-conductive media film, lower surface attaches the reflective medium film, and a wherein side of light guide plate is fixed with luminotron, attaches the deielectric-coating that is in the light around the light guide plate.
This above-mentioned luminotron can be light emitting diode (LED), and this light emitting diode can be versicolor light emitting diode.
This above-mentioned light-conductive media film has intensive microgroove, and light transmission is good.
The upper surface of this above-mentioned light guide plate is a shiny surface, and lower surface has intensive microgroove.
This above-mentioned reflective medium film and the deielectric-coating that is in the light all are light tight films.
Colored backlight display screen of the present utility model is owing to use light guide plate and the light-conductive media film with intensive microgroove, and this light guide plate and luminotron be enclosed in the reflective medium film and be in the light between the deielectric-coating, make colored light that light emitting diode sends in reflective medium film and repeatedly the reflection of being in the light between the deielectric-coating, pass through light guide plate several times, make full and uniform being dispersed in the light guide plate of light, after the light-conductive media film launch, uniform colored light is passed colourless full impregnated LCDs again and is exhaled, and presents colored effect backlight.
