Description
Technical field
The utility model relates to a kind of display backlight, belongs to display technology field.
Background technology
Along with liquid crystal display is more and more universal, to its profile and lightening requirement also more and more higher.Can backlight be the critical component of backlight module in liquid crystal display, be also to determine whole display reduce thickness, one of essential condition increasing its integrated level.Existing backlight is generally the side being fixed on light guide plate by the LED lamp bar of several upwards bright dipping, and the width of such LED directly determines the minimum of a value of light guide plate, cannot effectively reduce the integral thickness of backlight.
Summary of the invention
The utility model technical issues that need to address are: the backlight of existing liquid crystal display, it is generally the side being fixed on light guide plate by the LED lamp bar of several upwards bright dipping, the width of such LED directly determines the minimum of a value of light guide plate, cannot effectively reduce the integral thickness of backlight.
The utility model takes following technical scheme:
A kind of display backlight, comprises light guide plate, lamp bar, bright enhancement film; Described lamp bar comprises FPC flexible base board 1 and LED side light emitting diode 2, and light emitting diode 2 interval, described LED side is arranged on described FPC flexible base board 1, and its light emission direction is parallel to described FPC flexible base board 1; Light guide plate 3 side has open slot, and described open slot side has sinking position, the FPC flexible base board 1 being welded with LED side light emitting diode 2 is assembled to the sinking position of light guide plate 3, and with planes align on light guide plate 3, described upper plane is fitted described bright enhancement film.
Further, described LED side light emitting diode 2 is arranged at equal intervals on described FPC flexible base board 1.
Further, the overall rectangular structure of described light guide plate 3.
Further, described open slot is arranged at equal intervals on light guide plate 3.
Further, the thickness of light guide plate 3 is slightly larger than the height of LED side light emitting diode 2.
The beneficial effects of the utility model are:
1) FPC flexible base board 1, has the advantages that distribution density is high, lightweight, thickness is thin, bending property is good, can better be attached on light guide plate.
2) LED side light emitting diode 2 is embedded in the open slot of light guide plate 3 along with the installation of FPC flexible base board 1.Because be that side is luminous, so the light sent directly can inject light guide plate inside in open slot, to reach object spot light being converted to planar light source.
3) thickness of light guide plate 3 only need be a bit larger tham the height of LED side light emitting diode 2.As long as the LED side light emitting diode 2 chosen is highly enough little, light guide plate 3 supporting with it can accomplish the thickness much smaller than conventional light guide plate, and the requirement also for realizing the lightening of whole display and high integration becomes possibility.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
See Fig. 1-Fig. 7, the critical piece of backlight is by light guide plate, the compositions such as lamp bar and all kinds of bright enhancement films.
See Fig. 1-Fig. 3, wherein lamp bar is made up of FPC flexible base board 1 and LED side light emitting diode 2.FPC flexible base board 1 is the FPC FPC thinner than conventional line plate thickness.LED side light emitting diode 2 is the LED of side emitting, namely welds in the circuit board, and light emission direction is parallel to FPC FPC.
See Fig. 4-Fig. 5, light guide plate 3 is that optical grade PMMA particle is used high temperature by application emission forming machine, high pressure injects cooling forming in mould.Its side has open slot, and the size of open slot and spacing are mated with LED side light emitting diode 2.And process is done in light guide plate 3 open slot side.
See Fig. 6-Fig. 7, the FPC flexible base board 1 being welded with LED side light emitting diode 2 is assembled to light guide plate 3, forms an entirety.FPC flexible base board 1 is fixed on the sinking position of light guide plate 3, with planes align on it, can not affect fit on this plane all kinds of bright enhancement film and liquid crystal display.
Due to the height of LED side light emitting diode can do very little, be generally 0.4mm or 0.6mm, so the thickness of light guide plate also can accomplish about 0.5mm or 0.7mm accordingly.
The spacing of LED side light emitting diode 2 is directly proportional to its lighting angle, usually chooses the LED side light emitting diode that lighting angle is not less than 120 °, reduces backlight shadow and is formed, improve the uniformity.
Utilize FPC flexible base board 1 bendable folding endurance, and the plasticity of light guide plate, can arc be realized completely, the special-shaped backlights such as circle.
FPC flexible base board 1, has the advantages that distribution density is high, lightweight, thickness is thin, bending property is good, can better be attached on light guide plate.
LED side light emitting diode 2 is embedded in the open slot of light guide plate 3 along with the installation of FPC flexible base board 1.Because be that side is luminous, so the light sent directly can inject light guide plate inside in open slot, to reach object spot light being converted to planar light source.
The thickness of light guide plate 3 only need be a bit larger tham the height of LED side light emitting diode 2.As long as the LED side light emitting diode 2 chosen is highly enough little, light guide plate 3 supporting with it can accomplish the thickness much smaller than conventional light guide plate.Also the requirement for realizing the lightening of whole display and high integration becomes possibility.
