Abstract
The utility model relates to a single-back light double-output LCD (Liquid Crystal Display) which is characterized in that an LED (Light Emitting Diode) lamp is arranged in the middle of a PCB (Printed Circuit Board), wherein the LED lamp penetrates through the PCB; a reflecting hood is arranged outside the LED lamp and is semi-circle shaped and faces to the same direction together with the LED lamp; a through hole is further formed in the middle of the reflecting hood; the diameter of the through hole is smaller than that of the LED lamp; light scattering plates are arranged among a first LCD screen, a second LCD screen and the PCB. As output of double surfaces can be achieved through only one backlight source, the utilization rate of resource is increased, and the production cost of enterprises is lowered.
Description
Technical field
The utility model relates to a kind of display technique field, is specifically related to a kind of list dual output LCD backlight.
Background technology
LCD display is a kind of digital display technique, and it can filter light source by the liquid crystal cell coloured filter, on flat panel, produces image.With traditional cathode ray tube (CRT) display screen, compare, LCD display have take up room little, low-power consumption, low radiation, flicker free, reduce the advantage such as visual fatigue and widespread use.
Usually the LCD display of dual output is to need two backlights to work simultaneously, is unfavorable for so the reasonable utilization of resource, has also increased the production cost of enterprise simultaneously.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of list dual output LCD backlight, only with a backlight, just can realize two-sided output, has improved resource utilization, has reduced the production cost of enterprise.
The technical scheme that the utility model adopts is: a kind of list dual output LCD backlight, comprise pcb board, described pcb board both sides are respectively arranged with a LCD screen and the 2nd LCD screen, described pcb board middle part is provided with the LED lamp, and described LED lamp runs through pcb board, and this LED lamp outside is covered with reflection shield, described reflection shield is semicircle, towards consistent, this reflection shield middle part also is provided with through hole with the LED lamp, and described through-hole diameter is less than the diameter of LED lamp; Between a described LCD screen, the 2nd LCD screen and pcb board, all be provided with astigmatism plate.
All upward, and reflection shield is fixed on pcb board for described LED lamp and reflection shield, and the LED lamp is fixed in reflection shield.
Described LCD screen both sides all are connected with pin, and the pin lower end is fixed on pcb board.
The beneficial effects of the utility model are: owing to taking technique scheme, effectively utilized on LED lamp straight line luminous flux large, the principle that the side luminous flux is little, make a backlight realize two-sided output, improved resource utilization, reduced cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of list dual output LCD backlight, comprise pcb board 1, described pcb board 1 both sides are respectively arranged with LCD screen the 2 and the 2nd a LCD screen 3, and described pcb board 1 middle part is provided with LED lamp 4, described LED lamp 4 runs through pcb board 1, these LED lamp 4 outsides are covered with reflection shield 5, and described reflection shield 5 is semicircle, with LED lamp 4 towards consistent, these reflection shield 5 middle parts also are provided with through hole 6, and described through hole 6 diameters are less than the diameter of LED lamp 4; Between described LCD screen the 2, the 2nd a LCD screen 3 and pcb board 1, all be provided with astigmatism plate 7.All upward, and reflection shield 5 is fixed on pcb board 1 for described LED lamp 4 and reflection shield 5, and LED lamp 4 is fixed in reflection shield 5.On the straight line of LED lamp 4, luminous flux is large, and the side luminous flux is little, so the light on straight line enters astigmatism plate by through hole 6, makes light uniformly from a LCD screen 2, appearing; The luminous flux of LED lamp 4 sides is little, therefore the light of side is assembled to reinforcement by reflection shield 5, then enters lower astigmatism plate, uniformly from the 2nd LCD screen 3, appearing.Using fully that a LED lamp is not wasted can have been improved to resource utilization like this, reduce cost.
Described LCD screen both sides all are connected with pin 8, and pin 8 lower ends are fixed on pcb board 1.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
