For example, the planar surface shown in the figures may have rough and/or non-linear features, while the acute angles shown in the figures may be rounded. Therefore, the elements presented in the drawings are mainly for illustration, and are not intended to precisely describe the actual shapes of the elements, nor to limit the scope of the claims.
Fig. 1A is a schematic side view of a display device according to at least one embodiment of the invention. Referring to fig. 1A, the display device 100 includes a support 110a and a display component 120, wherein the support 110a is fixed to the display component 120. For example, the supporting member 110a may be adhered to the display member 120 by using an adhesive material, so that the supporting member 110a is fixed to the display member 120.
The display part 120 has a side 121, a bottom 122 and a top 123, wherein the top 123 is opposite to the bottom 122, and the side 121 connects the bottom 122 and the top 123. The display 120 may be a reflective display panel, so the display device 100 may be a reflective display, in which an image formed by the display 120 is presented on the top surface 123. The display unit 120 is, for example, an electrowetting display panel or an electrophoretic display panel.
At least a portion of the support 110a is fixed to the side 121 of the display part 120. Taking fig. 1A as an example, the entire support 110a may be fixed to the side 121, but the support 110a may not cover the bottom 122 of the display part 120 at all, as shown in fig. 1A. In addition, the support 110a may be adhered to the side 121 of the display part 120 by a glue material such that the entire support 110a is fixed to the side 121.
The display device 100 further includes a light guide plate 130a and a light emitting member 140, wherein the light guide plate 130a includes a light emitting portion 131 and a bending portion 132. The light emitting portion 131 is disposed on the top surface 123 of the display member 120. For example, the light emitting part 131 may be adhered to the top surface 123 of the display part 120 by an optical adhesive (Optically Clear Adhesive, OCA). The curved portion 132 is connected to the light-emitting portion 131 and extends from the light-emitting portion 131.
The bending portion 132 wraps the supporting member 110a, and the supporting member 110a can be surrounded by the bending portion 132 and the display component 120. The bending portion 132 has a light incident side 132a, and the light emitting member 140 is disposed on the light incident side 132a, wherein the display component 120 is located between the light emitting member 140 and the light emitting portion 131, as shown in fig. 1A. Further, the light emitting member 140 may be a light emitting diode (Light Emitting Diode, LED).
The display device 100 may further include a touch sensing panel 151 and a protective layer 152, wherein the protective layer 152 may be a glass plate or a transparent plastic plate. The touch sensing panel 151 is disposed on the light emitting portion 131, and the protection layer 152 is disposed on the touch sensing panel 151. The touch sensing panel 151 can be adhered to the light emitting portion 131 by using an optical adhesive (OCA), and the protective layer 152 can be adhered to the touch sensing panel 151, so that both the touch sensing panel 151 and the protective layer 152 can be fixed on the light guide plate 130a.
FIG. 1B is a schematic top view of the flattened light guide plate and light emitting device of FIG. 1A. Referring to fig. 1A and 1B, in the present embodiment, the light guide plate 130a has flexibility, and the bending portion 132 can be bent or flattened, wherein fig. 1A shows the bent light guide plate 130a, and fig. 1B shows the flattened light guide plate 130a. As shown in fig. 1B, the light incident side 132a is a surface side of the curved portion 132, and the light emitting element 140 is disposed on the light incident side 132a and can emit light toward the light incident side 132 a.
Referring to fig. 1A, when the light of the light emitting element 140 enters the curved portion 132 from the light incident side 132a, the light is reflected and transmitted in the curved portion 132 of the wrapping support 110a, so that the light can be transmitted to the light emitting portion 131. At least one of the upper surface 131a and the lower surface 131b of the light emitting portion 131 may be provided with a plurality of scattering patterns (not shown), such as dots or grooves, so that light can be emitted from the upper surface 131 a.
Compared with the conventional display device with a light guide plate, the light guide plate 130a with the curved portion 132 can guide the light of the light emitting element 140 and make the light uniformly exit from the light emitting portion 131 after passing through the curved portion 132, so as to reduce or avoid uneven brightness caused by hot spot phenomenon, thereby improving the quality of the display device 100. In addition, it should be noted that, in the present embodiment, the number of the light emitting elements 140 included in the display device 100 is only one, but in other embodiments, the display device 100 may include a plurality of light emitting elements 140. Therefore, the light emitting members 140 shown in the drawings do not limit the number of light emitting members 140 included in the display device 100.
Since the light guide plate 130a has flexibility, the supporting member 110a covered by the bending portion 132 can support the bending portion 132 to prevent the bending portion 132 from being deformed by collision. Second, the supporting member 110a can support the bending portion 132 so that the bending portion 132 is not excessively bent. Thus, the supporting member 110a can control the curvature of the bending portion 132, and the supporting member 110a can reduce or avoid the light leakage in the bending portion 132, thereby improving the image brightness of the display device 100.
Fig. 1C is a schematic top view of another light guide plate applied to the display device in fig. 1A. Referring to fig. 1C, the light guide plate 130C in fig. 1C can be applied to the display device 100. In other words, the light guide plate 130a in fig. 1A may be replaced with the light guide plate 130c. The light guide plate 130c is similar to 130a. For example, the light guide plate 130c has flexibility, and includes a light emitting portion 131, a light incident side 133c, and a curved portion 133, and the curved portion 133 connects the light emitting portion 131.
Unlike the light guide plate 130a, the light incident side 133c of the bending portion 133 has a groove (not labeled) for accommodating the light emitting element 140, so that the light emitting element 140 can be embedded in the light incident side 133c of the bending portion 133. Thus, the light emitted by the light emitting element 140 can be substantially completely incident on the curved portion 133, so as to enhance the image brightness of the display device 100. In other embodiments, the display device 100 may include a plurality of light emitting elements 140, and the light emitting elements 140 may be accommodated in at least one groove located on the light incident side 133c. Accordingly, fig. 1C does not limit the number of both the light emitting member 140 and the groove of the bent portion 133.
Fig. 1D is a schematic perspective view of the display component and the support in fig. 1A. Referring to fig. 1A and 1D, the support member 110a may have a semicircular column shape, so the support member 110a may include a plane S11 and a cylindrical curved surface S12, wherein the plane S11 is connected to the side 121 of the display component 120. For example, the plane S11 of the support 110a may be adhered to the side 121 by an adhesive material so that the support 110a can be fixed to the display part 120.
In this embodiment, the support 110a may extend along the side 121 and cover the entire side 121, wherein the support 110a may extend from one side of the side 121 to the opposite side, as shown in fig. 1D. However, in other embodiments, the width of the supporting member 110a may be smaller than the thickness T12 of the display member 120, so that the supporting member 110a does not cover the entire side 121 and part of the side 121 is exposed. Accordingly, fig. 1A is for illustration only and does not limit the need for the support 110a to cover the entire side 121. Further, the width of the support 110a may be greater than or equal to half the thickness T12.
Fig. 1E is a perspective view of another support member applied to the display device in fig. 1A. Referring to fig. 1E, the supporting member 110a of the display device 100 may be replaced by a plurality of supporting members 110E. In terms of appearance, these supports 110e may be considered as being divided by the support 110a in fig. 1D. The supports 110e cover a portion of the side 121 so that a portion of the side 121 is not covered by the supports 110e, wherein the supports 110e may be aligned along the side 121. The function of these supports 110e is the same as that of the support 110a. Specifically, the supporting members 110e can also support the bending portion 132 to avoid the bending portion 132 from being deformed due to collision, and prevent the bending portion 132 from being excessively bent, so as to reduce or avoid light leakage in the bending portion 132.
In particular, in the present embodiment, the light guide plate 130a has flexibility, but in other embodiments, the light guide plate 130a may have rigidity, and the bending portion 132 may be formed by injection molding. In other words, in other embodiments, the curved portion 132 is not only inflexible, but also does not flatten. Therefore, the light guide plate 130a is not limited to have flexibility. In other embodiments, only the bending portion 132 of the light guide plate 130a may have flexibility.
Fig. 2A is a schematic side view of a display device according to another embodiment of the invention, and fig. 2B is a schematic perspective view of the display unit and the supporting member in fig. 2A. Referring to fig. 2A and 2B, the display device 200 of the present embodiment is similar to the display device 100 of the previous embodiment. For example, the display device 200 is a reflective display and includes a light guide plate 230, a display component 120, a light emitting element 140, a touch sensing panel 151 and a protective layer 152, wherein the light guide plate 230 includes a light emitting portion 131 and a bending portion 232 connected to the light emitting portion 131, and the bending portion 232 may be the bending portion 132 or 133 of the foregoing embodiment. In other words, the light guide plate 230 may be the aforementioned light guide plate 130a or 130c.
Unlike the display device 100 of the previous embodiment, in the present embodiment, the display device 200 includes a plurality of support members 210, wherein the support members 210 are aligned along the side 121. Each support 210 is fixed to the side 121 and the bottom 122 of the display part 120. Specifically, each support 210 includes a recess 211 for the display member 120, wherein the bottom 122 and the side 121 of the display member 120 can form a corner (not shown), and the corner can be disposed in the recess 211.
Each groove 211 may have a first plane S21 and a second plane S22 connecting the first plane S21, wherein the first plane S21 and the second plane S22 may be substantially equal in area. The first plane S21 and the second plane S22 may both be connected to the surface of the display component 120, where the first plane S21 is connected to the side 121 and the second plane S22 is connected to the bottom 122. The width W21 of the first plane S21 is smaller than the width of the side 121, but is greater than or equal to half the width of the side 121, wherein the width of the side 121 corresponds to the thickness T12 of the display part 120. Thus, each support 210 covers a portion of the side 121 and does not cover the edge of the top 123.
The support 210 may be shaped as a preferably scalloped cylinder (major sector of cylinder), so the support 210 also includes a cylindrically curved surface 212. The cylindrical curved surface 212 extends from the edge of the first plane S21 and the edge of the second plane S22, and the center axis of the cylindrical curved surface 212 is located at the junction of the first plane S21 and the second plane S22. Therefore, a straight line intersecting both the first plane S21 and the second plane S22 in fig. 2A is this circular mandrel.
In the embodiment shown in fig. 2A, both the first plane S21 and the second plane S22 may be substantially perpendicular, so that cross-section of the support 210 along a plane perpendicular to the first plane S21 and the second plane S22 may be seen as a cross-section in the shape of a preferred sector, wherein the central angle a21 of this preferred sector is significantly greater than 180 degrees, e.g. about 270 degrees.
It should be noted that in the present embodiment, the display device 200 includes a plurality of supporting members 210, and the supporting members 210 are aligned along the side 121, but in other embodiments, the display device 200 may include only one supporting member 210, and the supporting member 210 may extend along the side 121, wherein the supporting member 210 may extend from one side of the side 121 to the opposite side, like the supporting member 110a shown in fig. 1D. Therefore, the display device 200 may include only one support 210, and the present embodiment does not limit the number of supports 210 included in the display device 200.
Fig. 3 is a schematic side view of a display device according to another embodiment of the present invention. Referring to fig. 3, the display device 300 of the present embodiment is similar to the display device 200 of the previous embodiment, except that: the at least one support 310 included in the display device 300 is not a perfectly sector column in shape and thus is significantly different from the shape of the support 210.
Specifically, the support 310 also has a first plane S21, a second plane S32, and a cylindrical curved surface 312. However, the cylindrical curved surface 312 extends only from the edge of the first plane S21, does not extend from the second plane S32, and the cylindrical curved surface 312 does not connect the second plane S32. Next, the area of the first plane S21 is smaller than the area of the second plane S32, so that the area of the support 310 connected to the side 121 is smaller than the area connected to the bottom 122.
The display device 300 may include only one support 310 or include a plurality of supports 310. When the display device 300 includes only one support 310, the support 310 may extend along the side 121, wherein the support 310 may extend from one side of the side 121 to the opposite side, as in the support 110a shown in fig. 1D. When the display device 300 includes a plurality of supports 310, the supports 310 may be aligned along the side 121, as with the plurality of supports 210 shown in fig. 2B.
It is specifically noted that in the above embodiments, the supporting members 110a, 110e, 210 and 310 respectively include the cylindrical curved surfaces S12, 212 and 312, but in other embodiments, the supporting members included in the three display devices 100, 200 and 300 may not include any cylindrical curved surfaces. Accordingly, the shapes of the supports 110a, 110e, 210 and 310 disclosed in the drawings are for illustration only and are not limiting. In addition, the supporting members 110a, 110e, 210 and 310 can be made of soft materials, such as silica gel, rubber or polyurethane foam (e.g., PORON), so that the supporting members 110a, 110e, 210 and 310 can be flexible.
Fig. 4 is a schematic side view of a display device according to another embodiment of the invention. Referring to fig. 4, a display device 400 of the present embodiment is similar to the display device 200 of the previous embodiment. For example, the display device 400 includes not only the light guide plate 230 and the support 410, but also the display part 440, wherein the support 410 may be one of the supports 110a, 110e, 210 and 310 in the previous embodiments. However, unlike the display device 200 of the foregoing embodiment, the display device 400 of the present embodiment is a transmissive display and further includes a circuit board 420, wherein the support 410 is fixed to the circuit board 420, and at least a portion of the support 410 is fixed to a side surface of the circuit board 420, as shown in fig. 4.
Specifically, the display component 440 is a transmissive display panel, and the circuit board 420 is electrically connected to the display component 440. For example, the circuit board 420 may be electrically connected to the display component 440 through the flexible cable 450. The circuit board 420 may have a plurality of chips for controlling the display unit 440 to display images, and the display unit 440 is, for example, a liquid crystal display panel, wherein the light emitting portion 131 of the light guide plate 230 is disposed between the display unit 440 and the circuit board 420, as shown in fig. 4.
When the light emitting element 140 emits light, the light emitted by the light emitting element 140 can be emitted through the light guide plate 230, so that the light can be incident on the display member 440 from the light guide plate 230. Thus, the display device 400 can display images on the display unit 440. In addition, the display device 400 may further include a light reflecting layer 460, wherein the light reflecting layer 460 may be formed on the light emitting portion 131 and between the circuit board 420 and the light emitting portion 131, and the light reflecting layer 460 may be a metal layer. The reflective layer 460 can reflect the light of the light emitting device 140, thereby improving the brightness of the image of the display device 100.
In summary, compared with the existing display device having the light guide plate, the light guide plate having the curved portion can guide the light of the light emitting element, and make the light uniformly exit from the light emitting portion after passing through the curved portion, so as to reduce or avoid uneven brightness caused by hot spot phenomenon, thereby improving the quality of the display device.
Although the present invention has been described with reference to the above embodiments, it should be understood that the invention is not limited thereto, but may be modified or altered without departing from the spirit and scope of the invention.
