Description

背光模組及顯示裝置Backlight module and display device

本發明係關於一種顯示技術，特別是一種背光模組及顯示裝置。The invention relates to a display technology, especially a backlight module and a display device.

目前的顯示裝置的設計趨勢由以往的體積龐大、厚重的外型衍變成薄型化以及輕量化的方向發展，而且顯示裝置的邊框的寬度漸漸趨向窄邊框的設計，使得顯示裝置整體的體積縮小且在相同尺寸的顯示裝置下所能看到的顯示畫面的面積更大，視覺效果更好。The current design trend of the display device has evolved from the previous bulky, heavy appearance to thin and light weight, and the width of the frame of the display device gradually tends to a narrow frame design, which makes the overall size of the display device shrink and The area of the display screen that can be seen under the display device of the same size is larger and the visual effect is better.

但是對於習知的具有窄邊框的顯示裝置而言，由於邊框窄化的緣故，窄邊框較不易遮蔽背光模組的光學膜片的邊緣。也就是說，顯示面板的顯示區會更靠近背光模組的光學膜片的邊緣。因此，容易導致光學膜片與背光模組之間的定位區域容易暴露於顯示畫面的顯示區。However, for a conventional display device having a narrow frame, the narrow frame is less likely to cover the edge of the optical film of the backlight module due to the narrower frame. In other words, the display area of the display panel will be closer to the edge of the optical film of the backlight module. Therefore, it is easy to cause the positioning area between the optical film and the backlight module to be easily exposed to the display area of the display screen.

本發明一實施例提出一種背光模組，其包括背框、限位基座、擋壁以及光學膜片組。背框具有底蓋及側壁，且側壁圍設於底蓋以形成空間。限位基座包括底板及至少一擋片。底板設置於底蓋上，且擋片立於底板的上表面上。底板具有至少一第一導引槽。擋壁包括板體以及至少一第一定位柱，板體立於底板的上表面上，且第一定位柱位於板體的下表面並穿設在第一導引槽中。其中，板體的長軸方向大致上垂直於第一導引槽的延伸方向。光學膜片組位於空間內且包括第一光學膜片及第二光學膜片。第一光學膜片鄰近於擋壁的邊緣具有凹口，且板體位於凹口內。第二光學膜片堆疊於第一光學膜片上且具有限位孔，且擋片穿設於限位孔內。其中，第一定位柱可位移地定位於第一導引槽中，以透過板體限制第一光學膜片於空間中的位置。An embodiment of the present invention provides a backlight module, which includes a back frame, a limiting base, a blocking wall, and an optical film set.

FIG. 2 is a partial schematic perspective view of the backlight module corresponding to FIG. 1. FIG. 3 is an exploded view corresponding to the backlight module of FIG. 1. 4 is an exploded view corresponding to the limit base and the retaining wall of FIG. 1. For convenience of description, the side wall 112 of FIG. 1 is shown with an imaginary line; FIG. 2 omits the second optical film 142 of FIG. 1; FIG. 3 omits the optical film group 140 of FIG. 1, so it can be displayed. The internal structure and configuration of the backlight module 100 are shown. Please refer to FIGS. 1 to 4, the backlight module 100 includes a back frame 110, a limiting base 120, a blocking wall 130 and an optical film set 140. The limiting base 120 is disposed on the back frame 110, and the blocking wall 130 is disposed on the limiting base 120. The optical film group 140 includes at least one optical film (the first optical film 141 and the second optical film 142 are shown in FIG. 1 ), and the at least one optical film is limited to the back frame 110 by the blocking wall 130 Space H.

背框110具有底蓋111及側壁112。側壁112圍設於底蓋111的邊緣且連接底蓋111的邊緣，使得側壁112與底蓋111之間形成空間H。The back frame 110 has a bottom cover 111 and a side wall 112. The side wall 112 surrounds and connects the edge of the bottom cover 111, so that a space H is formed between the side wall 112 and the bottom cover 111.

限位基座120包括底板121及至少一擋片122。底板121設置於背框110的底蓋111上。於一實施例中，底板121設置鄰近於側壁112的底蓋111上。底板121具有至少一第一導引槽G1，且第一導引槽G1的延伸方向係由空間H往側壁112的方向延伸。擋片122立於底板121的上表面1221上。於一實施態樣中，限位基座120包括二個擋片122，且此二擋片122之間相隔一距離且分別位於底板121相對的兩端。此外，須說明的是，擋片122的數量及位置僅作為示例，而非對本發明實施例的限定。The limiting base 120 includes a bottom plate 121 and at least one blocking piece 122. The bottom plate 121 is disposed on the bottom cover 111 of the back frame 110. In an embodiment, the bottom plate 121 is disposed on the bottom cover 111 adjacent to the side wall 112. The bottom plate 121 has at least one first guiding groove G1, and the extending direction of the first guiding groove G1 extends from the space H toward the side wall 112.

In one embodiment, the limiting base 120 includes two baffles 122, and the two baffles 122 are separated by a distance and located at opposite ends of the bottom plate 121, respectively. In addition, it should be noted that the number and position of the baffles 122 are only examples, rather than limiting the embodiments of the present invention.

擋壁130包括板體131以及至少一第一定位柱132。板體131為一板狀塊材。第一定位柱132位於板體131的下表面1311且由下表面1311向外凸出。板體131立於限位基座120的底板121的上表面1211上。第一定位柱132穿設在第一導引槽G1中，且第一定位柱132可位移地定位於第一導引槽G1中。其中，板體131的長軸方向大致上垂直於第一導引槽G1的延伸方向。於此，擋壁130可活動地（例如是可位移地）設置於限位基座120上，且擋壁130可以依循第一導引槽G1的延伸方向位移且可以定位於限位基座120上。也就是說，擋壁130與側壁112之間的距離可以沿第一導引槽G1而變化。第一定位柱132的數量及位置可以視第一導引槽G1的數量及位置而定。於一實施態樣中，如圖4所繪示，擋壁130包括二個第一定位柱132，且此二第一定位柱132分別對應二個第一導引槽G1的位置。此外，須說明的是，第一定位柱132及第一導引槽G1的數量及位置僅作為示例，而非對本發明實施例的限定。The blocking wall 130 includes a plate body 131 and at least one first positioning post 132. The plate body 131 is a plate-shaped block. The first positioning post 132 is located on the lower surface 1311 of the plate body 131 and protrudes outward from the lower surface 1311. The plate body 131 stands on the upper surface 1211 of the bottom plate 121 of the limiting base 120. The first positioning post 132 is penetrated in the first guide groove G1, and the first positioning post 132 is movably positioned in the first guide groove G1. The long axis direction of the plate body 131 is substantially perpendicular to the extending direction of the first guide groove G1. Here, the blocking wall 130 is movably (for example, displaceably) disposed on the limiting base 120, and the blocking wall 130 can be displaced according to the extending direction of the first guide groove G1 and can be positioned on the limiting base 120 on. That is, the distance between the blocking wall 130 and the side wall 112 may vary along the first guide groove G1. The number and position of the first positioning posts 132 may depend on the number and position of the first guide grooves G1. In one embodiment, as shown in FIG. 4, the blocking wall 130 includes two first positioning posts 132, and the two first positioning posts 132 respectively correspond to the positions of the two first guide grooves G1. In addition, it should be noted that the numbers and positions of the first positioning posts 132 and the first guide grooves G1 are only examples, rather than limiting the embodiments of the present invention.

光學膜片組140容置於此空間H內。光學膜片組140包括第一光學膜片141及第二光學膜片142。第一光學膜片141的鄰近於擋壁130的邊緣1411具有凹口N，且凹口N對應擋壁130的板體131。亦即，板體131位於凹口N內。第二光學膜片142堆疊於第一光學膜片141上。第二光學膜片142具有限位孔L，且擋片122穿設於限位孔L內。於此實施例中，第一光學膜片141可以為擴散板，第二光學膜片142可以為但不限於擴散片、反射片、增亮片、或反射式增亮片等光學膜。The optical diaphragm group 140 is accommodated in this space H. The optical film group 140 includes a first optical film 141 and a second optical film 142. The edge 1411 of the first optical film 141 adjacent to the blocking wall 130 has a notch N, and the notch N corresponds to the plate body 131 of the blocking wall 130. That is, the plate body 131 is located in the recess N. The second optical film 142 is stacked on the first optical film 141. The second optical film 142 has a limiting hole L, and the blocking piece 122 is inserted into the limiting hole L. In this embodiment, the first optical film 141 may be a diffusion plate, and the second optical film 142 may be, but not limited to, an optical film such as a diffusion film, a reflection film, a brightness enhancement sheet, or a reflection type brightness enhancement sheet.

於此，藉由擋壁130的第一定位柱132可位移地定位於第一導引槽G1中，以調節且限位第一光學膜片141於空間H中的位置；藉由限位基座120的擋片122穿設於限位孔L內，以使第二光學膜片142能夠承掛於限位基座120的擋片122。如此，限位基座120及擋壁130之間的相對位置能夠隨著擋壁130的位移而改變，藉此能夠實現調節光學膜片組140於空間H內的配置，而無須因應不同的背光模組100的設計而製作多套模具，也降低了製造成本。Here, the first positioning post 132 of the blocking wall 130 is movably positioned in the first guide groove G1 to adjust and limit the position of the first optical film 141 in the space H; The blocking piece 122 of the seat 120 is inserted into the limiting hole L, so that the second optical film 142 can be supported by the blocking piece 122 of the limiting base 120. In this way, the relative position between the limit base 120 and the blocking wall 130 can be changed according to the displacement of the blocking wall 130, whereby the arrangement of the optical diaphragm group 140 in the space H can be adjusted without having to deal with different backlights The design of the module 100 to produce multiple sets of molds also reduces manufacturing costs.

圖5為本發明另一實施例的背光模組的局部立體示意圖。圖6為對應圖5的背光模組的局部立體示意圖。圖7為對應圖5的背光模組的***圖。圖8為對應圖5的限位基座及擋壁的***圖。其中，為了方便說明起見，圖5的側壁112以假想線繪示；圖6省略了圖5的第二光學膜片142；圖7省略了圖5的光學膜片組140，故，可顯示出背光模組200內部的結構及配置情況。請參閱圖5至圖8，於一些實施例中，背光模組200更包括卡扣件150，且卡扣件150可活動地（例如是可位移地）設置於限位基座120上。卡扣件150包括本體151及至少一第二定位柱152。第二定位柱152位於本體151的下表面1511且由下表面1511向外凸出。背框110的側壁112鄰近於凹口N之處具有開口W1，且限位基座120的底板121更具有至少一第二導引槽G2。本體151卡合或是嵌合於側壁112的開口W1。第二定位柱152穿設在第二導引槽G2中，且第二定位柱152可位移地定位於第二導引槽G2中。其中，第二導引槽G2的延伸方向平行於第一導引槽G1的延伸方向。於此，卡扣件150可以依循第二導引槽G2的延伸方向可活動地朝向擋壁130位移且可以定位於限位基座120上。也就是說，卡扣件150與擋壁130之間的距離可以沿第二導引槽G2而變化。5 is a partial schematic perspective view of a backlight module according to another embodiment of the invention. FIG. 6 is a partial perspective view of the backlight module corresponding to FIG. 5. 7 is an exploded view of the backlight module corresponding to FIG. 5. 8 is an exploded view corresponding to the limit base and the retaining wall of FIG. 5. For convenience of description, the side wall 112 of FIG. 5 is shown by an imaginary line; FIG. 6 omits the second optical film 142 of FIG. 5; FIG. 7 omits the optical film group 140 of FIG. 5, so it can be displayed. The internal structure and configuration of the backlight module 200 are shown. Please refer to FIG. 5 to FIG. 8. In some embodiments, the backlight module 200 further includes a buckle 150, and the buckle 150 is movably (eg, displaceably) disposed on the limiting base 120. The fastener 150 includes a body 151 and at least one second positioning post 152. The second positioning post 152 is located on the lower surface 1511 of the body 151 and protrudes outward from the lower surface 1511. The side wall 112 of the back frame 110 has an opening W1 adjacent to the recess N, and the bottom plate 121 of the limiting base 120 further has at least one second guide groove G2. The body 151 is engaged or fitted into the opening W1 of the side wall 112. The second positioning post 152 penetrates the second guide groove G2, and the second positioning post 152 is movably positioned in the second guide groove G2. The extending direction of the second guide groove G2 is parallel to the extending direction of the first guide groove G1. Here, the fastener 150 can be movably displaced toward the blocking wall 130 according to the extending direction of the second guide groove G2 and can be positioned on the limiting base 120. That is to say, the distance between the buckle 150 and the blocking wall 130 may vary along the second guide groove G2.

第二定位柱152的數量及位置可以視第二導引槽G2的數量及位置而定。於一實施態樣中，如圖8所繪示，卡扣件150包括一個第二定位柱152，且限位基座120的底板121具有一個位於二個第一導引槽G1之間的第二導引槽G2。此第二定位柱152對應此第二導引槽G2的位置。此外，須說明的是，第二定位柱152及第二導引槽G2的數量及位置僅作為示例，而非對本發明實施例的限定。The number and position of the second positioning posts 152 may depend on the number and position of the second guide grooves G2. In an embodiment, as shown in FIG. 8, the fastener 150 includes a second positioning post 152, and the bottom plate 121 of the limiting base 120 has a first position between two first guiding grooves G1 Two guide grooves G2. The second positioning post 152 corresponds to the position of the second guide groove G2. In addition, it should be noted that the numbers and positions of the second positioning posts 152 and the second guide grooves G2 are only examples, rather than limitations on the embodiments of the present invention.

於一些實施例中，如圖4及圖8所繪示，板體131具有穿孔U。本體151的內側面1512朝向空間H凸出，且本體151的內側面1512可活動地朝向板體131位移並且通過於板體131的穿孔U。於一實施態樣中，本體151的內側面1512朝向空間H凸出以形成一長凸條，也就是說，本體151的形狀可呈現類似於L形，如圖8所繪示。不過，於其他實施態樣中，本體151的形狀亦可以視設計而呈現其他合適的形狀（圖未繪示）。In some embodiments, as shown in FIGS. 4 and 8, the board 131 has a through hole U. The inner side surface 1512 of the body 151 protrudes toward the space H, and the inner side surface 1512 of the body 151 is movably displaced toward the plate body 131 and passes through the perforation U of the plate body 131. In one embodiment, the inner side surface 1512 of the body 151 protrudes toward the space H to form a long ridge, that is to say, the shape of the body 151 may be similar to an L shape, as shown in FIG. 8. However, in other embodiments, the shape of the body 151 can also take on other suitable shapes depending on the design (not shown).

圖9為對應圖4中區域A的局部放大示意圖。在一些實施例中，如圖9所繪示，第一導引槽G1的相對二內槽面G11分別具有多個凸部T1與多個凹部S1，且同一內槽面G11的此些凸部T1與此些凹部S1接續相連且交替排列。換言之，其中之一內槽面G11朝向相對的另一內槽面G11而具有多個突起以形成多個所述凸部T1，而此些凸部T1中任意相鄰二個凸部T1的相連處形成所述凹部S1。位於相對二內槽面G11的此些凸部T1相對設置且此些凹部S1相對設置。也就是說，其中之一內槽面G11的各個凸部T1都對應其相對的另一內槽面G11的各個凸部T1，且其中之一內槽面G11的各個凹部S1都對應其相對的另一內槽面G11的各個凹部S1。第一定位柱132由板體131的下表面1311向外凸出且穿設在第一導引槽G1中。當第一定位柱132位移時，第一定位柱132的表面抵頂相對二內槽面G11的相對二凸部T1且順沿相對二凸部T1的表面而滑動。於此，擋壁130於限位基座120上的位移量（可視第一導引槽G1的長度而定）可藉由第一定位柱132於相對二內槽面G11的所滑動的相對二凸部T1的數量來調節。當第一定位柱132定位時，第一定位柱132位於相對二內槽面G11的相對二凹部S1之間。於此，擋壁130定位於限位基座120的底板121。FIG. 9 is a partially enlarged schematic view corresponding to area A in FIG. 4. In some embodiments, as shown in FIG. 9, the two inner groove surfaces G11 of the first guide groove G1 respectively have a plurality of convex portions T1 and a plurality of concave portions S1, and the convex portions of the same inner groove surface G11 T1 and these concave portions S1 are continuously connected and arranged alternately. In other words, one of the inner groove surfaces G11 faces the other inner groove surface G11 and has a plurality of protrusions to form a plurality of convex portions T1, and any adjacent two of the convex portions T1 are connected The recess S1 is formed at the place. The convex portions T1 located opposite the two inner groove surfaces G11 are oppositely arranged and the concave portions S1 are oppositely arranged. That is to say, each convex portion T1 of one inner groove surface G11 corresponds to each convex portion T1 of the other inner groove surface G11, and each concave portion S1 of one inner groove surface G11 corresponds to its opposite Each recess S1 of the other inner groove surface G11. The first positioning post 132 protrudes outward from the lower surface 1311 of the plate body 131 and penetrates in the first guide groove G1. When the first positioning post 132 is displaced, the surface of the first positioning post 132 abuts against the opposing two convex portions T1 of the two inner groove surfaces G11 and slides along the surface of the opposing two convex portions T1. Here, the amount of displacement of the retaining wall 130 on the limit base 120 (depending on the length of the first guide groove G1) can be determined by the first positioning post 132 sliding relative to the two inner groove surfaces G11. The number of convex portions T1 is adjusted. When the first positioning post 132 is positioned, the first positioning post 132 is located between the opposing two concave portions S1 of the opposing two inner groove surfaces G11. Here, the blocking wall 130 is positioned on the bottom plate 121 of the limiting base 120.

圖10為對應圖8中區域B的局部放大示意圖。如圖10所繪示，於一些實施例中，第二導引槽G2的相對二內槽面G21分別具有多個凸部T2與多個凹部S2，且同一內槽面G21的此些凸部T2與此些凹部S2接續相連且交替排列。換言之，其中之一內槽面G21朝向相對的另一內槽面G21而具有多個突起以形成多個所述凸部T2，而此些凸部T2中任意相鄰二個凸部T2的相連處形成所述凹部S2。位於相對二內槽面G21的此些凸部T2相對設置且此些凹部S2相對設置。也就是說，其中之一內槽面G21的各個凸部T2都對應其相對的另一內槽面G21的各個凸部T2，且其中之一內槽面G21的各個凹部S2都對應其相對的另一內槽面G21的各個凹部S2。第二定位柱152由本體151的下表面1511向外凸出且穿設在第二導引槽G2中。當第二定位柱152位移時，第二定位柱152的表面抵頂相對二內槽面G21的相對二凸部T2且順沿相對二凸部T2的表面而滑動。於此，卡扣件150於限位基座120上的位移量可藉由第二定位柱152於相對二內槽面G21的所滑動的相對二凸部T2的數量來調節。當第二定位柱152定位時，第二定位柱152位於相對二內槽面G21的相對二凹部S2之間。於此，卡扣件150定位於限位基座120的底板121。FIG. 10 is a partially enlarged schematic view corresponding to area B in FIG. 8. As shown in FIG. 10, in some embodiments, the two inner groove surfaces G21 of the second guide groove G2 respectively have a plurality of convex portions T2 and a plurality of concave portions S2, and the convex portions of the same inner groove surface G21 T2 is continuously connected with these concave portions S2 and arranged alternately.

The convex portions T2 located opposite the two inner groove surfaces G21 are oppositely arranged and the concave portions S2 are oppositely arranged. That is to say, each convex portion T2 of one inner groove surface G21 corresponds to each convex portion T2 of the other inner groove surface G21, and each concave portion S2 of one inner groove surface G21 corresponds to its opposite Each recess S2 of the other inner groove surface G21. The second positioning post 152 protrudes outward from the lower surface 1511 of the body 151 and penetrates into the second guide groove G2. When the second positioning post 152 is displaced, the surface of the second positioning post 152 abuts against the opposing two convex portions T2 of the opposing two inner groove surfaces G21 and slides along the surface of the opposing two convex portions T2. Here, the amount of displacement of the fastener 150 on the limiting base 120 can be adjusted by the number of the relative two convex portions T2 that the second positioning post 152 slides relative to the two inner groove surfaces G21. When the second positioning post 152 is positioned, the second positioning post 152 is located between the opposing two concave portions S2 of the opposing two inner groove surfaces G21. Here, the fastener 150 is positioned on the bottom plate 121 of the limiting base 120.

於此，藉由第一導引槽G1及第二導引槽G2的內槽面（內槽面G11及內槽面G21）的凸部（凸部T1及凸部T2）及凹部（凹部S1及凹部S2）而使得第一定位柱132及第二定位柱152得以可位移地定位於第一導引槽G1及第二導引槽G2的內槽面。Here, by the convex portions (convex portions T1 and convex portions T2) and concave portions (concave portions S1) of the inner groove surfaces (inner groove surface G11 and inner groove surface G21) of the first guide groove G1 and the second guide groove G2 And the concave portion S2) so that the first positioning post 132 and the second positioning post 152 can be displaceably positioned on the inner groove surfaces of the first guide groove G1 and the second guide groove G2.

於此，藉由調整限位基座120及擋壁130之間的相對位置來實現光學膜片組140的配置，從而無須因應不同的顯示裝置300的設計而製作多套模具，也降低了製造成本。此外，藉由卡扣塊153穿設膠框160的卡扣孔W4，以使膠框160能夠透過卡扣件150而卡合於背框110。Here, by adjusting the relative position between the limit base 120 and the baffle 130 to realize the configuration of the optical film group 140, there is no need to produce multiple sets of molds in response to the different design of the display device 300, which also reduces the manufacturing cost. In addition, the buckle block 153 penetrates the buckle hole W4 of the plastic frame 160 so that the plastic frame 160 can be locked to the back frame 110 through the buckle 150.

於遮蓋部171的垂直投影方向上，前框170的遮蓋部171可以遮蔽支撐部161、限位基座120、擋壁130及卡扣件150。於一些實施例中，擋壁130的垂直投影範圍位於遮蓋部171的垂直投影範圍之內。於一些實施例中，如圖15所繪示，限位孔L的最鄰近於板體131的內表面1312的邊緣L2與側壁112的內表面1122之間具有第一寬度R1，遮蓋部171具有第二寬度R2，且第一寬度R1小於等於第二寬度R2。於此，可以透過調整限位基座120及擋壁130之間的相對位置來調整光學膜片組140的配置，以使光學膜片組140的邊緣區域（第一光學膜片141的凹口N或是第二光學膜片142的限位孔L）不會暴露於顯示區M1中。In the vertical projection direction of the cover portion 171, the cover portion 171 of the front frame 170 can cover the support portion 161, the limiting base 120, the blocking wall 130 and the fastener 150. In some embodiments, the vertical projection range of the blocking wall 130 is within the vertical projection range of the covering portion 171. In some embodiments, as shown in FIG. 15, the edge L2 of the limiting hole L closest to the inner surface 1312 of the board 131 and the inner surface 1122 of the side wall 112 have a first width R1, and the covering portion 171 has The second width R2, and the first width R1 is less than or equal to the second width R2. Here, the arrangement of the optical film group 140 can be adjusted by adjusting the relative position between the limit base 120 and the baffle wall 130, so that the edge area of the optical film group 140 (the recess of the first optical film 141 N or the limiting hole L) of the second optical film 142 will not be exposed in the display area M1.

於一些實施例中，顯示裝置300可以更包括發光源（圖未繪示），且發光源容置於空間H內，以提供顯示面板180顯示影像時所需的光線。發光源可以是發光二極體（Light-Emitting Diode，LED）、冷陰極螢光燈（Cold-Cathode Fluorescent Lamps，CCFLs）或電激發光元件（Electroluminescence，EL）。In some embodiments, the display device 300 may further include a light emitting source (not shown), and the light emitting source is accommodated in the space H to provide light required for the display panel 180 to display an image. The light emitting source may be a light-emitting diode (LED), a cold-cathode fluorescent lamp (Cold-Cathode Fluorescent Lamps, CCFLs), or an electroluminescence element (Electroluminescence, EL).

於一實施例中，限位基座120、擋壁130以及卡扣件150的分布位置可隨著不同顯示裝置的設計考量而改變。於一些實施態樣中，限位基座120、擋壁130以及卡扣件150可以是分布於對應顯示裝置的其中之一個側邊，如同此些圖式所繪。不過，於其他實施態樣中，限位基座120、擋壁130以及卡扣件150的數量也可以是多個且分布於顯示裝置的不同的側邊，例如是限位基座120、擋壁130以及卡扣件150可以為各為二個且分別分布於顯示裝置的其中之二個側邊。In an embodiment, the distribution positions of the limiting base 120, the blocking wall 130, and the buckle 150 can be changed according to design considerations of different display devices. In some embodiments, the limit base 120, the blocking wall 130, and the buckle 150 may be distributed on one side of the corresponding display device, as depicted in these drawings. However, in other embodiments, the number of the limiting base 120, the blocking wall 130, and the fastener 150 may also be multiple and distributed on different sides of the display device, for example, the limiting base 120, the blocking The wall 130 and the fastener 150 may be two and distributed on two sides of the display device respectively.

綜上所述，本發明實施例之背光模組及顯示裝置，其藉由第一定位柱可位移地定位於第一導引槽中，以透過板體調節且限位第一光學膜片於空間中的位置；藉由擋片穿設於限位孔內，以使第二光學膜片得以承掛。此外，藉由卡扣塊穿設膠框的卡扣孔，以使膠框能夠透過卡扣件而卡合於背框。如此，限位基座及擋壁之間的相對位置能夠隨著擋壁的位移而改變，藉此能夠實現調節光學膜片組於空間內的配置，使光學膜片組的邊緣區域不會暴露於顯示區中，且無須因應不同的背光模組及顯示裝置的設計而製作多套模具。相對於背光模組及顯示裝置來說，本發明實施例可透過調節限位基座及擋壁之間的相對位置而適用於不同邊框寬度的顯示裝置，進而降低了製造成本。In summary, the backlight module and the display device according to the embodiments of the present invention are movably positioned in the first guide groove by the first positioning post to adjust and limit the first optical film through the plate The position in the space; the second optical film can be hung by the stopper passing through the limit hole. In addition, the buckle block is provided with a buckle hole of the plastic frame, so that the plastic frame can be locked to the back frame through the buckle. In this way, the relative position between the limit base and the baffle wall can be changed according to the displacement of the baffle wall, whereby the arrangement of the optical film group in the space can be adjusted, so that the edge area of the optical film group is not exposed In the display area, there is no need to produce multiple sets of molds in response to the design of different backlight modules and display devices. Compared with the backlight module and the display device, the embodiments of the present invention can be applied to display devices with different frame widths by adjusting the relative position between the limit base and the barrier wall, thereby reducing the manufacturing cost.
