Please refer to Fig. 3, the back light unit 120b of the display module 200 of the present embodiment is side injection type backlight unit.Back light unit 120a comprises rectangular light guide plate 122 and a light source 124, and wherein light source 124 can be fluorescent tube, light-emitting diode light bar (LED light bars) or other suitable light source.Rectangular light guide plate 122 is such as the position being arranged at back light unit 120a in Fig. 1, and one of the corresponding rectangular light guide plate of light source 124 122 long limit is arranged.In addition, aforesaid Support Level 150 is such as arrange corresponding to the pair of short edges of rectangular light guide plate 122.In other words, the display module 200 of the present embodiment has two Support Level 150.
The back light unit 120b of the present embodiment can comprise a pedestal 126 further.Pedestal 126 can in order to carry aforesaid rectangular light guide plate 122 and light source 124.Furthermore, pedestal 126 comprise one bottom 126a, a junction 126b and a top 126c, wherein connecting portion 126b connect bottom 126a and top 126c.Rectangular light guide plate 122 and light source 124 are arranged on the 126a of bottom, and light source 124 is between bottom 126a and top 126c.
In the present embodiment, display panel 130, except the upper surface S2 being bearing on the part of protuberance 160b, is also bearing on the upper surface S6 of top 126c.In addition, pedestal 126 is such as metal material, can heat conduction and reflection ray.Therefore, can be imported in rectangular light guide plate 122 by the most light of light source 124 outgoing, and the light entered in rectangular light guide plate 122 can transmit in the direction by bottom 126a reflection and toward display panel 130, or past rectangular light guide plate 122 is transmitted toward the direction of display panel 130 relative to one end transmission of light source 124 again, and make the distribution of the light of back light unit 120b outgoing more even.Certainly, the back light unit 120b of the present embodiment also can comprise other blooming (being such as diffusion sheet, prismatic lens etc.) further, is configured in rectangular light guide plate 122, to promote the utilization factor of light or to increase the homogeneity etc. of bright dipping.
In the present embodiment, display module 200 utilizes Support Level 150 to carry the lower surface S1 of display panel 130 pair of short edges, reduce framework 160 occupies display module 200 volume in the pair of short edges place near back light unit 120a whereby, two long limits of display panel 130 are then bearing on the top 126c of protuberance 160b and pedestal 126 respectively.Therefore, display module 200 can have the design of narrow frame in this to minor face.In other words, under the display module of same size, the display module 200 of the present embodiment can have the viewing area of large-size.Or under the viewing area of same size, the size of the display module 200 of the present embodiment can be done less.
Fig. 4 is the diagrammatic cross-section of the display module of yet another embodiment of the invention.Please refer to Fig. 4, the display module 300 of the present embodiment has similar structure to the display module 200 of Fig. 3 embodiment, Support Level 150 number that both Main Differences are in the display module 300 of the present embodiment is three, wherein the pair of short edges of the corresponding rectangular light guide plate of Support Level 150 122 and the long limit setting away from light source 124.Therefore, protuberance 160b can be set in the framework 160 of the other end of light source 124, and the protuberance 160b of aforementioned framework 160 can be replaced to carry the lower surface S1 of display panel 130 by Support Level 150.
Thus, the display module 300 of the present embodiment, except reducing framework 160 except the area of display module occupied by pair of short edges 300, also can reduce framework 160 in the area occupied by the long limit away from light source 124.In other words, compared to display module 200, the display module 300 of the present embodiment can make the opposite side near the long limit of light source 124 have the design of narrow frame further.Therefore, under the display module of same size, the display module 300 of the present embodiment can have the viewing area of large-size.Or under the viewing area of same size, the size of the display module 300 of the present embodiment can be done less.
In other embodiments, display module 300 also can this refers to body 160a by removing framework 160() reduce further framework 160 in backboard 110 groove occupied by area, and then make four of display module 300 limits all can have the design of narrow frame.
In sum, the present invention replaces the protuberance of framework to carry at least side of the lower surface of display panel with Support Level, the width of at least side of the framework of display module is reduced, and then occupies the area of less display module.Therefore, the frame of display module is narrowed.
Although the present invention discloses as above with aforesaid preferred embodiment; but itself and be not used to limit the present invention; any person of ordinary skill in the field without departing from the spirit and scope of the present invention; can carry out numerous variations and modification to it, therefore scope of patent protection of the present invention should define with this instructions appending claims and be as the criterion.
