Abstract

The utility model is suitable for a TV and provides an LED side backlight module, an LCD (liquid crystal display) device and an LCD TV. The LED side backlight module consists of a light guide plate and an LED lamp strip. The light guide plate is provided with at least one inclined edge, and the LED lamp strip is arranged on the inclined edge. In the embodiment of the utility model, the light guide plate is a hexagon with four inclined edges. One LED lamp strip is respectively arranged on each inclined edge. An included angle between each inclined edge and the horizontal line is within 0 to 15 DEG. Both ends of each LED lamp strip are respectively connected with a connector. The utility model adopts the light guide plate with the inclined edge, and arranges the shorter LED lamp strip on the inclined edge, so as to be beneficial for decreasing the cost of the LED side backlight module in large size. Meanwhile, the utility model can be manufactured into the thinner LCD device and the LCD TV with the LCD device, and the cost is low.

Description

A kind of LED side module backlight, LCD and liquid crystal TV set
Technical field
The utility model belongs to technical field of television sets, relates in particular to a kind of LED-backlit module, LCD and liquid crystal TV set.
Background technology
Along with the fast development of science and technology, lcd technology is more and more ripe, and TV also develops into present liquid crystal display from traditional kinescope.LCDs is passive luminous display screen, and liquid crystal itself is not luminous, so LCDs needs module backlight that light source is provided, according to the classification of light source, can be divided into CCFL module backlight, LED-backlit module etc.The color reducibility of LED-backlit module is good, be easy to realize subregion control, becomes the main flow backlight of LCDs.The LED-backlit module can be divided into LED side module backlight and direct-light type LED backlight module again according to the difference of LED position.Frivolous LCD TV has become the market mainstream, and the lightening of liquid crystal display also is inevitable.The ultra-thin realization of the ultra-thin main backrest optical mode group of liquid crystal display.Module backlight will be accomplished ultra-thin general employing LED side module backlight.
LED side module backlight generally adopts aluminum base PCB (Printed Circuit Board, printed circuit board (PCB)) plate to dispel the heat, and described aluminum base PCB plate is provided with drive circuit.As shown in Figure 1, described LED side module backlight is made of LGP 1 and the LED lamp bar 2 of being located at LGP 1 upper and lower limit, the light that LED lamp bar sends is injected from LGP, and by the site of LGP reflection, light becomes from the LGP exiting surface and penetrates by light behind the LGP.When making the large scale liquid crystal display, need to adopt LED lamp bar with long aluminium base, described long aluminium base processing technology complexity, cost height, thereby large scale liquid crystal display, cost is also high.
The utility model content
The purpose of this utility model is to provide a kind of LED side module backlight, is intended to solve the high problem of prior art cost.
Another purpose of the present utility model is to provide LCD.
Another purpose of the present utility model is to provide liquid crystal TV set.
The utility model is achieved in that a kind of LED side module backlight, is made of LGP and LED lamp bar, and described LGP has at least one hypotenuse, and described LED lamp bar is located on the described hypotenuse.
Among the utility model embodiment, described LGP is the hexagon with four hypotenuses.
Among the utility model embodiment, respectively establish a LED lamp bar on described four hypotenuses.
Among the utility model embodiment, described hypotenuse and horizontal angle are 0~15 °.
Among the utility model embodiment, each described LED lamp bar two ends is equipped with connector.
Another order of the present utility model is achieved in that a kind of LCD, and it has aforementioned LED side module backlight.
Another order of the present utility model is achieved in that a kind of liquid crystal TV set, and it has the foregoing liquid crystal display.
The utility model has adopted the LGP with hypotenuse, short LED lamp bar can be provided with on this hypotenuse, helps reducing the cost of large scale LED side module backlight.Described LED lamp bar is located at respectively on four hypotenuses of hexagon LGP, and the lamp bar of symmetrical distribution guarantees the uniformity of module group backlight.The hypotenuse angle of inclination of described LGP is less, avoids module vertically to be widened.Shorter LED lamp bar two ends are provided with connector, reduce the printed circuit cable tray of single led lamp bar, and the width of described LED lamp bar can be done forr a short time, so just can make thinner LCD, and cost is lower.Liquid crystal TV set with described LCD, cost are also low.。
Description of drawings
Fig. 1 is the structural representation of the LED side module backlight that provides of prior art.
Fig. 2 is the structural representation of the LCD that provides of the utility model.
Fig. 3 is the structural representation of the LED side module backlight that provides of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, the LCD main body 3 that the utility model embodiment provides is the stratiform stacked structure, described main body 3 left and right sides are provided with housing 4, metal backing 5 is established at described main body 3 back sides, described main body 3 top layers are liquid crystal panel 6, described main body 3 bottoms are LED side module 7 backlight, are provided with some blooming pieces 8 between described liquid crystal panel 6 and the LED side module 7 backlight.5 heat radiations of described metal backing and protective action.
As shown in Figure 3, the LED side that the utility model embodiment provides module 7 backlight is made of LGP 9 and LED lamp bar 10, described LED lamp bar 10 adopts aluminum base PCB (Printed Circuit Board, printed circuit board (PCB)) plate, and LED11 and drive circuit thereof are located at aluminium base 12.LGP described in the present embodiment 9 is for having the hexagon of four hypotenuses 13, and described LED lamp bar 10 is located on the described hypotenuse 13, and the lamp bar of symmetrical distribution guarantees the uniformity of module group backlight; When making the large scale liquid crystal display, short LED lamp bar 10 is installed respectively on 9 four hypotenuses 13 of LGP, by the lamp bar that is spliced into Len req than short LED lamp bar 10, is made the required aluminium base 12 of this shorter LED lamp bar and process easily, cost is low.Described hypotenuse 13 is 0~15 ° with horizontal angle α, avoids module vertically to be widened.It is socket 14 that each LED lamp bar 10 two ends is respectively equipped with connector, for long aluminium base, the printed circuit cable tray is less on the described aluminium base 12, thereby the width of described LED lamp bar 10 can be done forr a short time, so just can make thinner LCD, and cost is lower.Liquid crystal TV set with described LCD, cost are also low.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
