Detailed description of the invention
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Fig. 1 is the structural representation of the back light module unit structure in correlation technique, as shown in Figure 1, back light module unit structure 1 in correlation technique often comprises the LED string 2 being arranged at side, and the LED string 2 in such as Fig. 1 is arranged at the edge, downside of back light module unit structure 1.Meanwhile, by arranging light guide plate 3 in the light path of LED string 2, Homogenization Treatments can be carried out to the light that LED string 2 penetrates.
But along with the reduction of screen light transmittance, the screen of electronic equipment also may exist dark situation, affected user and used; Simultaneously, due to the limited width of back light module unit structure 1, the limited amount of the LED that LED string 2 is arranged in the direction of the width, be difficult to promote brightness by increasing LED, when such as 5 cun of screens employings comprise the lamp string (comprising 12 LED lamp than LED string 2 as shown in Figure 1) of 16 LED lamp, the arrangement of LED is very compact.
Therefore, for the technical problem in above-mentioned correlation technique, Fig. 2 is the structural representation of a kind of back light module unit structure according to an exemplary embodiment, as shown in Figure 2, in technical scheme of the present disclosure, can arrange many LED strings.In such as Fig. 2, be provided with the first LED string 21 and the second LED string 22 in the upper edge of back light module unit structure 1 and lower edge place respectively; Quantity due to LED adds 1 times, and corresponding screen intensity also can increase by 1 times, thus solves screen light transmittance and to decline the low technical problem of the screen intensity that causes.
Meanwhile, Fig. 3-4 is perspective view of the light guide plate (light guide) according to an exemplary embodiment.LED string is arranged at wedge structure 4 place shown in the left arrow in Fig. 3, then light guide plate is by this wedge structure 4, by the light guiding opposite from LED string; In addition, as shown in Figure 3 and Figure 4, corresponding pattern 5 (pattern) is provided with in the front (as shown in Figure 3) of light guide plate and reverse side (as shown in Figure 4), this pattern 5 can be the line of rabbet joint shown in Fig. 3, also can be the shrinkage pool shown in Fig. 4 or projection, for realizing the Homogenization Treatments to light.
Therefore, the existence of pattern 5 makes light guide plate itself and uneven.In order to avoid in the situation shown in fig. 2, namely when the first LED string 21 and the second LED string 22 are directly arranged at the two ends up and down of light guide plate 3, because light guide plate 3 is uneven and cause screen exit rays uneven, affect Showing Effectiveness On Screen, the LED string in back light module unit structure and should be adaptive one by one between light guide plate.
For this reason, in technical scheme of the present disclosure, back light module unit structure comprises: many LED strings and polylith light guide plate one to one, and every bar LED displacement is in the end of the wedge structure side of corresponding light guide plate.Ratio as shown in Figure 5, still for the first LED string 21 and the second LED string 22, be respectively the first LED string 21 and the second LED string 22 and corresponding light guide plate 31 and light guide plate 32 are set, then the surface of light guide plate 31 comprises the pattern (not shown) that the emergent ray of the first LED string 21 can be made to be evenly distributed on the corresponding region of this light guide plate 31, and the surface of light guide plate 32 comprises the pattern (not shown) that the emergent ray of the second LED string 22 can be made to be evenly distributed on the corresponding region of this light guide plate 32.
In technical scheme of the present disclosure, every bar LED string all can be arranged along the side of back light module unit structure, and the first LED string 21 in such as Fig. 5 is arranged along the upper side edge of back light module unit structure 1, the second LED string 22 is arranged along the lower side of back light module unit structure 1.
Embodiment one
As an exemplary embodiment, when the first LED string 21 and the second LED string 22 respectively along back light module unit structure 1 side is arranged up and down time (the left and right side perpendicular bisector along back light module unit structure 1 is symmetrical arranged), light guide plate 31 and light guide plate 32 can adopt the symmetrical structure shown in Fig. 5 (the left and right side perpendicular bisector equally along back light module unit structure 1 is symmetrical arranged), then only need a design, light guide plate 31 and light guide plate 32 can be applied to simultaneously.
Embodiment two
As another exemplary embodiment, as shown in Figure 6: the first LED string 21 and the second LED string 22 also can arrange (perpendicular bisector of side up and down along back light module unit structure 1 is symmetrical arranged) along the left and right side of back light module unit structure 1 respectively, then light guide plate 31 and light guide plate 32 can adopt the symmetrical structure shown in Fig. 6 (perpendicular bisector of side up and down equally along back light module unit structure 1 is symmetrical arranged) equally.
Certainly, those skilled in the art should understand that: light guide plate 31 and light guide plate 32 might not adopt symmetric design, namely light guide plate 31 and light guide plate 32 also can adopt asymmetric design; Such as in the embodiment shown in fig. 7, the length of light guide plate 31 is greater than the length of light guide plate 32, and the pattern now on light guide plate 31 and light guide plate 32 also needs correspondingly to change, and needs to carry out independent design to light guide plate 31 and light guide plate 32 respectively.
Embodiment three
Although the first LED string 21 in Fig. 5-7 and the second LED string 22 all have employed symmetrical structure, LED string might not adopt symmetrical structure.Ratio as shown in Figure 8, except symmetrically arranged first LED string 21 and the second LED string 22,3rd LED string 23 and corresponding light guide plate 33 can also be set along the limit, left side of back light module unit structure 1, then light guide plate 33 be provided with the pattern (not shown) that the emergent ray of the 3rd LED string 23 can be made to be evenly distributed on the corresponding region of this light guide plate 33.
Those skilled in the art, at consideration description and after putting into practice disclosed herein disclosing, will easily expect other embodiment of the present disclosure.The application is intended to contain any modification of the present disclosure, purposes or adaptations, and these modification, purposes or adaptations are followed general principle of the present disclosure and comprised the undocumented common practise in the art of the disclosure or conventional techniques means.Description and embodiment are only regarded as exemplary, and true scope of the present disclosure and spirit are pointed out by claim below.
Should be understood that, the disclosure is not limited to precision architecture described above and illustrated in the accompanying drawings, and can carry out various amendment and change not departing from its scope.The scope of the present disclosure is only limited by appended claim.
