The embodiments of the present invention are disclosed in the following drawings, and for the purpose of clarity However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

The use of the terms first, second, and third, etc., is used to describe various elements, components, regions, layers, aspects and/or blocks. However, these elements, components, regions, layers, regions and/or blocks should not be limited by these terms. These terms are only used to identify a single element, component, region, layer, layer, and/or block.

1 and 2, wherein FIG. 1 is a cross-sectional view of a display device according to an embodiment of the present invention, and FIG. 2 is a partial enlarged view of a region M of FIG. 1. As shown, the display device includes a housing 100, a backlight module 200, an elastic body 300, and a display panel 400. The backlight module 200 is disposed in the housing 100. The backlight module 200 includes at least an optical film set 210, and the optical film set 210 has a central image area 212 and a peripheral fixed area 214. The peripheral fixed area 214 is adjacent to the central image area 212 and located at the side of the central image area 212, and the peripheral fixed area 214 extends across the frame 100, that is, the orthographic projection of the peripheral fixed area 214 overlaps the frame. Body 100. elasticity The body 300 has a fixing portion 310 and a positioning portion 320. The fixing portion 310 is disposed on the frame body 100, and the positioning portion 320 extends toward the optical film group 210 and is pressed across the peripheral fixing portion 214. The display panel 400 is located above the elastic body 300 and the optical film set 210, and the display panel 400 has a display area 402 and a light blocking portion 410. The light shielding portion 410 is adjacent to the display region 402, and the projected area of the light shielding portion 410 completely covers the positioning portion 320 and partially covers the peripheral fixing region 214.

Specifically, the light shielding portion 410 of the present embodiment is located at the periphery of the display region 402. The frame 100 has a first plane 102 and a second plane 104 , and the orthographic projection of the first plane 102 on the display panel 400 exceeds the light shielding portion 410 . The portion of the optical film set 210 (i.e., the peripheral fixed area 214) spans over the first plane 102. The fixing portion 310 of the elastic body 300 is disposed on the second plane 104. The positioning portion 320 protrudes from the second plane 104 and spans the portion of the pressing portion 214 that is disposed above the first plane 102, and the positioning portion 320 is The orthographic projection of the display panel 400 does not exceed the light shielding portion 410.

In this embodiment, the positioning portion 320 is used to straddle the peripheral fixing region 214 of the optical film group 210 to reduce the dark band range of the display region 402 of the display panel 400 adjacent to the light shielding portion 410. Specifically, in the present embodiment, the peripheral fixing region 214 of the optical film group 210 is spanned over the first plane 102, so the peripheral fixing region 214 is tilted toward the display panel 400 to change the traveling direction of the light beam. For example, a portion of the light beam originally intended to be projected around the display area 402 is deflected to another portion due to the raised portion of the peripheral fixed area 214, so that the display panel 400 is formed to extend toward the display area 402 at the display area 402 adjacent to the light shielding portion 410. a wide range of dark bands, resulting in display products Poor quality. However, in the present embodiment, the positioning portion 320 spans the peripheral fixing region 214 of the optical film group 210, and further, the positioning portion 320 straddles the peripheral fixing region 214 to prevent the optical film group 210 from being lifted, thereby reducing The beam is deflected to other locations and the beam is directed toward display area 402, thereby increasing the brightness around display area 402, and the extent of dark bands produced adjacent display block 410 in display area 402 can be reduced.

On the other hand, when the orthographic projection of the positioning unit 320 on the display panel 400 does not exceed the light shielding portion 410, that is, when viewed from above the display panel 400, the light shielding portion 410 can block the positioning portion 320, and the positioning portion 320 does not self-display the region 402. Exposed, the positioning portion 320 does not block the light beam passing through the display region 402.

In the embodiment, the backlight module 200 further includes a light guide plate 220 and a light source 230. The light source 230 is disposed on the same side of the positioning portion 320 and is disposed on a side surface 222 of the light guide plate 220. The light guide plate 220 is disposed on the frame 100. Inside. The light emitted by the light source 230 can enter from the side surface 222 of the light guide plate 220, and after traveling in the light guide plate 220, the light exit surface 224 of the light guide plate 220 is emitted, and then passes through the optical film set 210 to reach the display panel 400. Since the light source 230 is placed under the frame 100, even if the light source 230 is composed of a plurality of point light sources (such as light-emitting diodes), the light-dark uneven light beam generated between the point light sources can be blocked by the frame 100. . Even if some of the light unevenness is leaked from the light guide plate 220, since the partial peripheral fixed area 214 of the optical film set 210 is lifted up to the first plane 102, the raised peripheral fixed area 214 has a diffused point light source. The effect of (ie bright area), so that the light with uneven brightness can be further homogenized. However, the peripheral fixed area 214 will also expand. The dark areas between the point sources cause dark bands around the display area 402 of the display panel 400. In addition, if there is no positioning portion 320, the tilted portion of the optical film set 210 deflects the light beam around the display area 402 to other places, so that the range of the dark band is increased. However, in the present embodiment, the positioning portion 320 straddles the partial peripheral fixing region 214 of the optical film group 210, thereby deflecting the beam emission direction back to the display region 402, thereby improving the brightness around the display region 402 and reducing the display area. 402 is adjacent to the range of the dark band at the light blocking portion 410. In an embodiment, when the positioning portion 320 straddles the peripheral fixing region 214 of the optical film group 210, the dark band portion originally generated at the adjacent portion of the display region 402 and the light shielding portion 410 is reduced to the light shielding portion 410, thereby positioning The portion 320 does have the effect of reducing the dark band at which the display region 402 is adjacent to the light blocking portion 410.

In the present embodiment, the first plane 102 is located below the optical film set 210, so that the frame 100 can lift the optical film set 210 to improve the problem of uneven brightness. However, the frame 100 causes a portion of the peripheral fixing region 214 of the optical film group 210 to be lifted, thereby forming a wide range of dark bands at the display region 402 adjacent to the light shielding portion 410. Therefore, in general, it is possible to widen the area of the light shielding portion 410, thereby concealing the dark band caused by the optical film group 210 of the lifted portion, but it is difficult to achieve the effect of the narrow frame. However, in the present embodiment, since the positioning portion 320 straddles the peripheral fixing region 214 of the optical film group 210, such an arrangement can reduce the dark band range generated at the adjacent portion of the display region 402 and the light shielding portion 410 and enhance the display region. 402 weeks of brightness. When the brightness is increased, the width of the light shielding portion 410 of the display panel 400 can be narrowed, thereby achieving the purpose of narrowing the border.

As seen from Fig. 2, the side end 108 of the frame 100 has a first end face. The positioning portion 320 has a second end surface 322 , and the light shielding portion 410 has a third end surface 412 . The first end surface 106 , the second end surface 322 , and the third end surface 412 are both away from the light source 230 . In addition, the light source 230 has a virtual plane V that passes through its light emitting surface 232 and is parallel to the light emitting surface 232. Among the first end face 106, the second end face 322 and the third end face 412, the vertical distance between the second end face 322 and the virtual plane V is the smallest, the third end face 412 is second, and the first end face 106 and the virtual plane V are The vertical distance between them is the largest. When the vertical distance between the second end surface 322 and the virtual plane V is smaller than the vertical distance between the third end surface 412 and the virtual plane V, the light shielding portion 410 does not expose the positioning portion 320 when viewed above the display panel 400. The positioning portion 320 can cross the optical film group 210 to enhance the brightness around the display area 402, and reduce the dark band of the display area 402 adjacent to the light shielding portion 410. When the vertical distance between the first end surface 106 and the virtual plane V is greater than the vertical distance between the third end surface 412 and the virtual plane V, not only the optical film group 210 portion (ie, the peripheral fixing region 214) can be spanned. On the frame 100, the purpose of narrow borders can be achieved.

Please refer to FIG. 3, which is a partial enlarged view of a region P of FIG. 2. In this embodiment, the optical film group 210 portion (ie, the peripheral fixing region 214) is spanned on the frame 100, and is suspended from the frame 100 to form a curved surface, and the positioning portion 320 contacts and closely follows the curved surface. Specifically, since part of the optical film set 210 is lifted by the frame 100, the optical film set 210 has a curved surface. In addition, since the positioning portion 320 is a part of the elastic body 300 in the present embodiment, the positioning portion 320 has elasticity so that the positioning portion 320 can contact and abut against the optical film group 210.

Next, the force relationship of the optical film group 210 will be described in detail. please Referring to Fig. 4, it is a force diagram of the optical film set 210 of Fig. 3. In the present embodiment, the light guide plate 220 is disposed in the frame 100, and the optical film set 210 is disposed above the light guide plate 220 (all as shown in FIG. 1). By the frame 100, an upward supporting force F1 is formed below the peripheral fixing area 214 and adjacent to the side end 108 of the frame 100. On the other hand, the elastic body 300 has a pressing force F2 applied to the peripheral fixing portion 214 on the peripheral fixing portion 214, and the pressing force F2 and the supporting force F1 are opposite to each other, so the frame body The positioning portion 320 and the positioning portion 320 can collectively clamp the optical film group 210 by the supporting force F1 and the pressing force F2, thereby enhancing the ability of the positioning portion 320 to straddle the optical film group 210. The adjacent portion of the light shielding portion 410 and the display region 402 is located between the supporting force F1 and the pressing force F2.

In one or more embodiments, the supporting force F1 is at least a frame The 100 side end 108 and the light guide plate 220 are provided. In detail, the light guide plate 220 supports the frame body 100 by the side end 108 of the frame body 100, and the frame body 100 further supports a part of the peripheral fixing area 214 of the optical film group 210. Therefore, the light guide plate 220 and the side of the frame body 100 are supported. The 108 can collectively provide the support force F1 to the peripheral fixed area 214. In addition, in other embodiments, if the frame 100 is also supported by other members, the member supporting the frame 100 may also provide a partial support force F1.

In one or more embodiments, the pressing force F2 is at least positioned The portion 320 and the display panel 400 are provided. In detail, the housing 100 carries the display panel 400 by the elastic body 300, and thus the display panel 400 is applied to the elastic body 300 by gravity. On the other hand, as described above, the positioning portion 320 of the elastic body 300 contacts and abuts against the optical film group 210, so the elastic body 300 also Applying another gravity to the optical film set 210. That is to say, the gravity provided by the display panel 400 and the elastic body 300 respectively is combined into a pressing force F2 to press the peripheral fixing region 214 of the optical film group 210.

In one or more embodiments, the perimeter securing zone 214 has a fourth end face 216. The distance r1 from the position where the first end surface 106 of the edge end 108 of the frame 100 is projected to the peripheral fixing portion 214 to the fourth end surface 216 is greater than the position where the second end surface 322 of the positioning portion 320 is projected to the peripheral fixing portion 214 to the fourth end surface 216. Distance r2. Since the pressing force F2 is partially provided by the gravity of the display panel 400, the value of the pressing force F2 may be greater than the value of the supporting force F1. However, since the distance r2 is smaller than the distance r1, the moment formed by the pressing force F2 and the distance r2 can be balanced with the moment formed by the supporting force F1 and the distance r1, so that the positioning portion 320 and the frame 100 can jointly hold the optical film group. 210.

Please return to Figure 3. In the present embodiment, the first plane 102 and the second plane 104 are further connected by a connecting portion 112, and the connecting portion 112, the first plane 102 and the positioning portion 320 together form a receiving slot R. The vertical height Ha of the opening end Ra of the accommodating groove R is greater than the vertical height Hb of the bottom end Rb of the accommodating groove R with respect to the opening end Ra, that is, the first plane 102 is one lighter than the light emitting surface 224 of the light guide plate 220. The inclined surface helps the optical film set 210 to be smoothly disposed on the light guide plate 220 and the frame 100 to prevent the optical film set 210 from causing a large angle of bending at the edge 108 of the frame 100 to affect the light quality. . On the other hand, the fourth end surface 216 of the optical film group 210 may not contact the bottom end Rb of the accommodating groove R, that is, a gap between the fourth end surface 216 and the bottom end Rb of the optical film group 210 as an optical film. The set 210 is buffered by volume changes during thermal expansion and contraction.

Please return to Figure 2. The frame 100 may further have a recess 114, and the elastic body 300 is partially disposed on the recess 114. Further, the fixing portion 310 of the elastic body 300 is placed on the recess 114. The recessed portion 114 has the function of positioning, that is, when the display device is assembled, the fixing portion 310 of the elastic body 300 can directly abut the edge of the concave portion 114, thereby completing the setting of the elastic body 300, thereby shortening the assembly man-hour. On the other hand, the display device may further include a colloid 350 placed on the recess 114 and placed between the fixing portion 310 and the frame 100. The colloid 350 is used to bond and fix the elastic body 300 to the recess 114.

In the present embodiment, the elastomer 300 has a thickness T, and the recess 118 has a depth D that is greater than the depth D, wherein the thickness of the colloid 350 can be ignored. In other words, the positioning portion 320 of the elastic body 300 protrudes from the frame 100. Since the frame 100 has a certain hardness, the display panel 400 is placed on the elastic body 300, so that the display panel 400 can be prevented from contacting the frame 100. The upper slide causes friction and collision with the frame 100, resulting in damage of the display panel 400. In the present embodiment, the thickness T of the elastic body 300 may be about 0.4 mm to 0.8 mm, and the depth D may be about 0.3 mm to 0.5 mm. Basically, as long as the thickness T is greater than the depth D, the display panel 400 does not contact the frame. 100, all within the scope of the invention.

In the present embodiment, the material of the elastic body 300 may be rubber, polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), or polyurethane (polyurethane). The PU material or the silicone rubber may be in a foamed state. On the other hand, the elastic body 300 may also be a light absorbing material, but the invention is not limited thereto.

Then please return to Figure 1. In this embodiment, the display device can The back cover 500 and the front cover 600 are further included. At least a portion of the light guide plate 220 is disposed between the back cover 500 and the frame 100. The front cover 600 and the frame 100 collectively hold the display panel 400. It should be noted that in the first figure, the front cover 600 and the frame 100 do not directly contact the display panel 400. Such a structure can prevent the front cover 600 and the frame 100 from scratching the display panel 400. On the other hand, the backlight module 200 may further include a heat dissipation material 240 disposed between the light guide plate 220 and the back cover 500. The heat dissipating material 240 can be used to carry the light source 230, and the light source 230 can dissipate heat generated by itself by contacting the heat dissipating material 240 to extend the life of the light source 230.

Next, please refer to FIG. 5, which is a cross-sectional view of a display device according to another embodiment of the present invention. The difference between this embodiment and the embodiment of Fig. 1 lies in the shape of the display device. In the present embodiment, the display panel 400, the backlight module 200, the frame 100, the front cover 600 and the back cover 500 are all bent in the same direction C, that is, the display device is a curved display device. In this arrangement, the projected area of the light-shielding portion 410 also completely covers the positioning portion 320 and partially covers the peripheral fixed portion 214, that is, the orthographic projection of the first plane 102 on the display panel 400 exceeds the light-shielding portion 410, and the positioning portion 320 is The orthographic projection of the display panel 400 does not exceed the light shielding portion 410. Further, if the display device is a flexible panel, when the display device as a whole is stretched into a flat panel, it is also necessary to ensure that a part of the peripheral fixing region 214 of the optical film group 210 can still straddle the housing 100. Other details of the present embodiment are the same as those of the embodiment of Fig. 1, and therefore will not be described again.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and those skilled in the art may, without departing from the spirit of the invention. And the scope of the invention is defined by the scope of the appended claims.
