Fig. 1 is a schematic cross-sectional view of a display device according to an embodiment of the disclosure. Referring to fig. 1, a display device 10 of the present embodiment may include a carrier 100, a backlight module 200, and a display panel 300. The backlight module 200 is disposed on the carrier 100, and the display panel 300 is disposed on the backlight module 200. Specifically, in the present embodiment, the carrier 100 is, for example, a metal jig having a curved edge, but not limited thereto. In the present embodiment, the carrier 100 may form a receiving groove 110, wherein the size of the receiving groove 110 may be larger than the size of the backlight module 200 and the size of the display panel 300, so that the backlight module 200 and the display panel 300 may be loaded in the receiving groove 110. The receiving groove 110 has a curved inner bottom surface 111 and a sidewall 112 connected to the inner bottom surface 111. In the present embodiment, the material of the carrier 100 is, for example, aluminum or other suitable metals, but not limited thereto.
In the present embodiment, the backlight module 200 is disposed in the receiving recess 110 of the carrier 100. Specifically, the backlight module 200 is attached to the curved inner bottom surface 111 of the receiving groove 110, so that the attached backlight module 200 can be curved, and the curved backlight module 200 can have a similar curvature (curvature) to the inner bottom surface 111 of the receiving groove 110. The backlight module 200 includes a driving substrate 210, a plurality of light emitting units 220, and a light reflecting structure 230. The driving substrate 210 may include a transistor, a capacitor, a power source, and other driving circuits to be electrically connected to the light emitting unit 220 and to drive the light emitting unit 220 to emit light. The driving substrate 210 may include a rigid substrate, a flexible substrate, or a combination thereof. For example, the material of the driving substrate 210 may include, but is not limited to, glass, quartz, sapphire (sapphire), ceramic, Polycarbonate (PC), Polyimide (PI), polyethylene terephthalate (PET), epoxy glass fiber, other suitable substrate materials, or a combination thereof. In the present embodiment, since the size of the receiving groove 110 may be larger than that of the driving substrate 210, a gap G1 is formed between the edge 211 of the driving substrate 210 and the sidewall 112 of the receiving groove 110.
In the present embodiment, a plurality of light emitting units 220 are disposed on the driving substrate 210. The light emitting unit 220 may include light emitting diodes of different colors, such as a red light emitting diode, a green light emitting diode, a blue light emitting diode, and/or a white light emitting diode, but not limited thereto.
In the present embodiment, the light reflection structure 230 is disposed on the driving substrate 210 and can extend beyond the edge 211 of the driving substrate 210. The light reflection structure 230 does not overlap the plurality of light emitting cells 220. The light reflecting structure 230 may contact the carrier 100. In the present embodiment, the light reflection structure 230 may be white glue or other suitable high reflection material, but is not limited thereto. In the present embodiment, the white glue material may include silica gel and white paste. The white paste may be, for example, a watercolor pigment and contains white particles. In some embodiments, the reflectivity of the light reflection structure 230 may be greater than the reflectivity of the carrier 100.
Specifically, in the present embodiment, the light reflection structure 230 may include a first light reflection structure 231 and a second light reflection structure 232. The first light reflecting structure 231 is disposed on the driving substrate 210 and located inside the edge 211 of the driving substrate 210, and the second light reflecting structure 232 is disposed outside the edge 211 of the driving substrate 210. In detail, the first light reflecting structure 231 is disposed on the driving substrate 210 and disposed on a portion of the driving substrate 210 between the light emitting units 220, such that the first light reflecting structure 231 can be overlapped on the driving substrate 210 and not overlapped on the plurality of light emitting units 220. The second light reflecting structure 232 is disposed in the gap G1 between the edge 211 of the driving substrate 210 and the sidewall 112 of the receiving groove 110 of the carrier 100, and is disposed on the inner bottom surface 111 of the portion exposed by the gap G1, so that the second light reflecting structure 232 does not overlap the driving substrate 210.
In addition, in the present embodiment, the light emitting unit 220 has a top surface 221 away from the driving substrate 210, the first light reflecting structure 231 has an upper surface 231a away from the driving substrate 210, and the second light reflecting structure 232 has an upper surface 232a of the carrier 100. The top surface 221 of the light emitting unit 220 may be higher than the upper surfaces 231a and 232a of the first and second light reflecting structures 231 and 232, so that the top surface 221 of the light emitting unit 220 is not covered by the first and second light reflecting structures 231 and 232 to affect the light emitting of the light emitting unit 220. The upper surface 232a of the second light reflecting structure 232 may also be higher than the upper surface 231a of the first light reflecting structure 231, so that the light emitted from the light emitting unit 220 to the edge 211 of the driving substrate 210 can be reflected by the second light reflecting structure 232 to increase the brightness of the edge of the display device 10 (or the backlight module 200). That is, in the present embodiment, the height of the light emitting unit 220 may be higher than the height of the second light reflecting structure 232 and the height of the first light reflecting structure 231, and the height of the second light reflecting structure 232 may be higher than the height of the first light reflecting structure 231.
In the embodiment, the second light reflecting structure 232 is disposed in the gap G1 between the edge 211 of the driving substrate 210 and the sidewall 112 of the receiving recess 110 of the carrier 100, so that the brightness of the edge of the display device 10 (or the backlight module 200) can be increased, and the light emitting efficiency of the backlight module 200 can be improved or the backlight module 200 can be protected. In detail, compared with other display devices having the shadow problem due to not filling the second light reflection structure in the gap G1, the display device 10 of the embodiment can increase the brightness of the edge of the display device 10 (or the backlight module 200) and improve the shadow problem by filling the second light reflection structure 232 in the gap G1. Therefore, compared to the other display devices, the brightness of the edge of the display device 10 (or the backlight module 200) of the embodiment can be increased by, for example, 10% to 32%, for example, from about 95-99% to about 108% and 132%. In addition, since the brightness increase of the edge of the display device 10 (or the backlight module 200) can increase the overall brightness of the display device 10 (or the backlight module 200) or can increase the light emitting efficiency of the backlight module 200, the backlight module 200 of the display device 10 of the embodiment can achieve the effect of 100% brightness with lower power consumption compared to the other display devices; in other words, the display device 10 of the present embodiment can have an effect of reducing power consumption. In addition, compared to the problem that the other display devices may be damaged due to the vibration of the external force (for example, when the driving substrate of the other display devices includes glass), the display device 10 of the embodiment can fix the backlight module 200 by filling the second light reflecting structure 232 into the gap G1 between the driving substrate 210 and the carrier 100, so as to achieve the protection effect.
In the embodiment, since the first light reflecting structure 231 and the second light reflecting structure 232 can be fabricated separately, the first light reflecting structure 231 and the second light reflecting structure 232 are not integrally formed, and a seam is formed between the first light reflecting structure 231 and the second light reflecting structure 232. For example, after a plurality of light emitting units 220 (fig. 1 schematically shows 5, but not limited thereto) are disposed on the driving substrate 210, the uncured first light reflecting structure 231 is coated on the driving substrate 210 of the portion exposed by the light emitting units 220; then, after the first light reflection structure 231 is thermally cured, the uncured second light reflection structure 232 is filled in the gap G1 between the driving substrate 210 and the carrier 100; then, the second light reflecting structure 232 is thermally cured. In the embodiment, the viscosity coefficient of the uncured second light reflecting structure 232 may be higher than that of the uncured first light reflecting structure 231, so that the uncured second light reflecting structure 232 is not easy to flow onto the upper surface 231a of the first light reflecting structure 231. In other embodiments, the first light reflecting structure and the second light reflecting structure may be integrally formed, so that the first light reflecting structure and the second light reflecting structure are continuous and have no gap. In other embodiments, the second light reflecting structure 232 may also be light cured.
In this embodiment, the backlight module 200 may further include an adhesive layer 240, a supporting substrate 250, a diffusion plate 260, and an optical film 270. The adhesive layer 240 is disposed between the driving substrate 210 and the carrier 100, so that the driving substrate 210 can be attached and fixed to the inner bottom surface 111 of the accommodating recess 110 of the carrier 100 through the adhesive layer 240. The support substrate 250 is disposed on the light emitting unit 220, and the support substrate 250 does not contact the light emitting unit 220. The distance D1 is between the supporting substrate 250 and the light reflecting structure 230, and the distance D1 is, for example, 6 mm, but not limited thereto. In the present embodiment, the distance D1 is, for example, a minimum distance measured in a direction from a side of the support substrate 250 facing the light emitting unit 220 to the upper surface 231a of the first light reflecting structure 231. The diffusion plates 260 (fig. 1 schematically shows 2 diffusion plates, but not limited thereto) are disposed on the light emitting units 220 and on the support substrate 250. The optical film 270 is disposed on the diffusion plate 260 such that the optical film 270 and the supporting substrate 250 are respectively disposed at two opposite sides of the diffusion plate 260. In the present embodiment, the optical film 270 may include prism sheets 271(BEF, fig. 1 schematically shows 2, but not limited thereto) and a privacy sheet 272, wherein the prism sheets 271 are disposed on the diffusion plate 260, and the privacy sheet 272 is disposed on the prism sheets 271, such that the prism sheets 271 are located between the privacy sheet 272 and the diffusion plate 260.
In the present embodiment, the display panel 300 is disposed on the anti-peeping sheet 272 of the backlight module 200, so that the backlight module 200 can provide light to the display panel 300. The backlight module 200 may be a direct-type backlight module, so that the light emitted from the backlight module 200 can be emitted toward the display panel 300, and in other embodiments, the anti-peeping sheet 272 may also be disposed on the display panel 300.
In summary, in the display device 10 of the embodiment of the disclosure, since the second light reflecting structures 232 of the light reflecting structures 230 can be disposed in the gap G1 between the driving substrate 210 and the carrier 100, compared to other display devices that have a shadow problem due to not filling the second light reflecting structures in the gap, the display device 10 of the embodiment can increase the brightness of the edge of the display device 10 (or the backlight module 200) by the second light reflecting structures 232 filled in the gap G1, so as to improve the shadow problem, improve the light emitting efficiency of the backlight module 200, or reduce the power consumption of the backlight module 200. In addition, the second light reflecting structure 232 disposed between the driving substrate 210 and the carrier 100 may also have a protection effect to reduce the damage of the backlight module 200 caused by the vibration of the external force.
Other examples will be listed below for illustration. It should be noted that the following embodiments follow the reference numerals and parts of the contents of the foregoing embodiments, wherein the same reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted. For the description of the omitted parts, reference may be made to the foregoing embodiments, and the following embodiments will not be repeated.
Fig. 2 is a schematic cross-sectional view of a display device according to another embodiment of the disclosure. Referring to fig. 1 and fig. 2, the display device 10a of the present embodiment is substantially similar to the display device 10 of fig. 1, and therefore, the same and similar components in the two embodiments are not repeated herein. The display device 10a of the present embodiment is different from the display device 10 in that, in the display device 10a of the present embodiment, the backlight module 200a further includes another driving substrate 210a, 210b (fig. 2 schematically shows 2, but not limited thereto).
Specifically, referring to fig. 2, in the present embodiment, the driving substrate 210 is disposed adjacent to and spliced with another driving substrate 210a, and the another driving substrate 210a is disposed adjacent to and spliced with another driving substrate 210 b. In the embodiment, since the gap G2 is formed at the joint between the driving substrate 210 and the other driving substrate 210a, and the gap G3 is also formed at the joint between the other driving substrate 210a and the other driving substrate 210b, when the first light reflecting structure 231 'of the light reflecting structure 230' is coated on the driving substrate 210, the other driving substrate 210a, and the other driving substrate 210b, the first light reflecting structure 231 'of the light reflecting structure 230' can be further extended and filled into the gap G2 between the driving substrate 210 and the other driving substrate 210a, and extended and filled into the gap G3 between the other driving substrate 210a and the other driving substrate 210 b.
Although in the display device 10a of the present embodiment, the first light reflecting structures 231 'on the driving substrate 210, the other driving substrate 210a and the other driving substrate 210b and the first light reflecting structures 231' in the gaps G2 and G3 may be integrally formed (i.e., the first light reflecting structures 231 'on the driving substrate 210, the other driving substrate 210a and the other driving substrate 210b and the first light reflecting structures 231' in the gaps G2 and G3 are continuous and have no gap therebetween), the disclosure is not limited thereto. In some embodiments, the first light reflecting structures on the driving substrate and the other driving substrate 210b and the first light reflecting structures in the gap may be fabricated separately, so that there is a seam (not shown) between the first light reflecting structures on the driving substrate and the other driving substrate and the first light reflecting structures in the gap.
In summary, in the display device according to the embodiment of the disclosure, the second light reflection structure of the light reflection structure may be disposed in the gap between the driving substrate and the carrier, so that, compared to other display devices having a shadow problem due to not filling the second light reflection structure in the gap, the display device according to the embodiment can increase the brightness of the edge of the display device (or the backlight module) by filling the second light reflection structure in the gap, thereby improving the shadow problem, increasing the light emitting efficiency of the backlight module, or reducing the power consumption of the backlight module. In addition, the second light reflection structure arranged between the driving substrate and the carrier also has a protection effect, so that damage of the backlight module caused by vibration of external force is reduced.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present disclosure, and not for limiting the same; while the present disclosure has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present disclosure.
