The invention will be described in more detail below with reference to the accompanying drawings. Like elements in the various figures are denoted by like reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. Moreover, certain well-known elements may not be shown in the figures.
In the following description, numerous specific details of the invention, such as structure, materials, dimensions, processing techniques and techniques of components, are set forth in order to provide a more thorough understanding of the invention. However, as will be understood by those skilled in the art, the present invention may be practiced without these specific details.
Example 1:
as shown in fig. 1 to 5, the present embodiment provides a backlight module 10 having a display area 11 and a non-display area 12 connected to the display area 11, the backlight module 10 includes: a light guide plate 2, a light source 3, a back plate 4, and a reflective sheet 5.
The light guide plate 2 includes a light exit surface 21 and a light entrance surface 22. The light source 3 is disposed on one side of the light incident surface 22 of the light guide plate 2 and located in the non-display region 12, and light from the light source 3 can enter the light guide plate 2 through the light incident surface 22. The back plate 4 is used for bearing the light guide plate 2 and the light source 3, and is arranged on one side of the light guide plate 2, which is far away from the light incident surface 22, and orthographic projections of the light guide plate 2 and the light source 3 on the back plate 4 are not overlapped. And a reflective sheet 5 at least partially disposed on a side of the light guide plate 2 away from the back plate 4 and located in the non-display region 12, wherein the reflective sheet 5 is used for reflecting light from the light guide plate 2, and the reflective sheet 5 includes a light shielding layer 51.
The backlight module 10 is a part of the display device, and the backlight module 10 has a display area 11 and a non-display area 12. The display region 11 corresponds to a region where the display device forms a display screen (a region where the pixel unit is located), and the non-display region 12 can be regarded as an edge region of the display region 11, and is used for arranging structures such as a lead and a driving circuit.
The light incident surface 22 of the light guide plate 2 is a surface for allowing light for forming a display image to enter the light guide plate 2, and the light enters the light guide plate 2 through the light incident surface 22, is finally emitted uniformly through the light emitting surface 21 of the light guide plate 2 under the action of the light guide plate 2, and is emitted to the array substrate 70 on one side of the backlight module 10 to form the display image of the display device.
The light source 3 is located in the non-display region 12 and corresponds to the light incident surface 22 of the light guide plate 2, so that the light source 3 emits light to the light incident surface 22 as much as possible and enters the light guide plate 2, thereby ensuring light utilization.
The back plate 4 is a structure for supporting the light guide plate 2 and the light source 3, and the light guide plate 2 and the light source 3 are located on the same side of the back plate 4. The orthographic projections of the light guide plate 2 and the light sources 3 on the back plate 4 are not overlapped, which is equivalent to that the arrangement direction of the light guide plate 2 and the light sources 3 is parallel to the back plate 4, that is, the light sources 3 are located on the side surface of the light guide plate 2 (the light incident surface 22 of the light guide plate 2 is located on the side surface of the light guide plate 2), thereby forming the side-in type backlight module 10.
At least a portion of the reflective sheet 5 is located on a side of the light guide plate 2 away from the back plate 4, so that light emitted from the light emitting surface 21 of the light guide plate 2 and emitted to the non-display region 12 can be reflected, and the light can re-enter the light guide plate 2, thereby avoiding light leakage or poor display. The light-shielding layer 51 of the reflective sheet 5 can absorb light directed thereto.
It should be noted that, in the backlight module 10 of the prior art, in order to realize a thin display device, a portion of the light guide plate 2 located in the display area 11 is generally thinner than a portion of the light guide plate 2 located close to the light source 3, so as to ensure that an area of the light incident surface 22 of the light guide plate 2 is sufficiently large, so that the light emergent surface 21 of the light guide plate 2 has a certain slope at a portion close to the display area 11, that is, the light emergent surface 21 of the light guide plate 2 is non-planar. Meanwhile, in order to realize a thin display device and ensure display performance, the structures (the reflective sheet 5, the bezel 6, etc.) located between the backlight module 10 and the array substrate 70 and located in the non-display region 12 are generally configured to be thinner, so that light (as indicated by dotted arrows in fig. 1 and 5) emitted from the light guide plate 2 of the non-display region 12 is likely to pass through the reflective sheet 5, the bezel 6, etc. and emit into the array substrate 70 located in the display region 11, thereby causing display defects, such as a firefly phenomenon.
The reflective sheet 5 of the backlight module 10 of this embodiment is provided with the light shielding layer 51, the light shielding layer 51 can absorb the light emitted to the reflective sheet 5, that is, if the light emitted from the light guide plate 2 of the non-display area 12 is emitted to the reflective sheet 5, a part of the light is reflected back to the light guide plate 2 by the reflective sheet 5, and a part of the light passing through the reflective sheet 5 is absorbed by the light shielding layer 51, so as to avoid the light from being emitted to the array substrate 70 of the display area 11, and further avoid the display failure (for example, the luminance at the position corresponding to the light source 3 is greater than the luminance at the other positions, which is expressed as the firefly phenomenon), thereby ensuring the display performance of the display.
Preferably, as shown in fig. 2 to 4, the light-shielding layer 51 includes a first portion 511 and a second portion 512 connected to each other, the first portion 511 is farther from the display region 11 than the second portion 512, and the light absorption of the first portion 511 is stronger than that of the second portion 512.
In other words, the light-shielding layer 51 of the reflective sheet 5 is divided into two parts: the first portion 511 is farther away from the display area 11, and the light absorption performance of the first portion 511 is better, so that it can be better ensured that the light of the light guide plate 2 or the light of the light source 3 in the non-display area 12 does not pass through the reflective sheet 5 and enter the array substrate 70 of the display area 11, and the phenomenon of poor display of the display device with the backlight module 10 can be well avoided; since the second portion 512 is closer to the display region 11, the light absorption of the second portion 512 of the light shielding layer 51 is weaker to ensure the light extraction rate of the light guide plate 2.
As can be seen from the above, the light shielding layer 51 of the reflective sheet 5 can ensure not only the light extraction rate of the light guide plate 2, but also the display brightness of the display device; and light can be prevented from being emitted from the light guide plate 2 of the non-display area 12 to the array substrate 70 of the display area 11, thereby preventing display defects from occurring.
Preferably, the first portion 511 of the light-shielding layer 51 is an ink layer.
In other words, the first portion 511 of the light-shielding layer 51 is disposed on the ink layer on the surface of the reflective sheet 5.
The light shielding layer 51 is easy to manufacture and low in manufacturing cost, so that the manufacturing cost of the backlight module 10 can be reduced.
Preferably, the light source 3 includes a plurality of point light sources, and the point light sources are arranged in an array or in a column.
That is, the light source 3 of the present embodiment is formed by a plurality of point light sources, and the point light sources are arranged in an array or a row, and if the point light sources are arranged in an array, the row direction of the point light sources is substantially parallel to the edge where the light incident surface 22 of the light guide plate 2 is located; if the point light sources are arranged in a row, the arrangement direction of the point light sources is substantially parallel to the edge of the light incident surface 22 of the light guide plate 2.
The structure of the light source 3 of the present embodiment may be other suitable structures, and is not limited to the above-described structures.
Specifically, the first case of the light-shielding layer 51 is: the second portion 512 of the light shielding layer 51 has a plurality of ink regions 5121 and a plurality of non-ink regions 5122, the ink regions 5121 and the non-ink regions 5122 are arranged at intervals along the edge of the light incident surface 22 of the light guide plate 2, and each ink region 5121 corresponds to one or one row of point light sources 3.
As shown in fig. 4, the ink area 5121 is an area having light absorbing property, and the non-ink area 5122 cannot absorb light and can only reflect light. Each ink zone 5121 corresponds to one or a row of point light sources, which corresponds to the placement of the ink zone 5121 in an area near a point light source, and the placement of the non-ink zone 5122 in a corresponding location at the gap between two point light sources.
In the ink area 5121 of the second portion 512, each ink area 5111 corresponds to one LED particle, the light in the area between two LED particles is dark, the light of each LED particle is strong, and the ink area 5121 can absorb part of the light and does not reflect back to the light guide plate 2, thereby reducing the non-uniform phenomenon of the picture of the display area 11, such as the firefly phenomenon; the ink area 5121 of the second portion 512 can ensure the light output of the light guide plate 2, so as to ensure the display brightness of the display device.
Further, each ink area may be a trapezoid, with the longer and shorter sides of the trapezoid being closer to the display area. The ink areas may be of other suitable shapes, not limited to those listed above.
Specifically, the second case of the light-shielding layer 51 is: the second portion 512 of the light-shielding layer 51 includes a plurality of ink dots.
As shown in fig. 3, the second portion 512 of the light-shielding layer 51 is formed by a plurality of ink dots disposed on the surface of the reflective sheet 5. The plurality of ink dots can prevent light from being emitted from the light guide plate 2 of the non-display area 12 to the array substrate 70 of the display area 11 on the premise of ensuring the high light-emitting rate of the light guide plate 2, thereby ensuring the display performance of the display device with the backlight module 10.
Preferably, the distribution density of the ink dots near the display area 11 is smaller than the distribution density of the ink dots far from the display area 11.
The light absorption performance of the area with low distribution density of the ink dots is weaker than that of the area with high distribution density of the ink dots, so that the light extraction rate of the light guide plate 2 can be further ensured, and the display brightness of the display device can be ensured; and it is possible to further prevent light from being emitted from the light guide plate 2 of the non-display area 12 to the array substrate 70 of the display area 11, thereby preventing display defects from occurring.
Preferably, the light shielding layer 51 is positioned on the surface of the reflective sheet 5 close to the light guide plate 2.
In this case, the light shielding layer 51 may be disposed on the surface of the reflective sheet 5 adjacent to the light guide plate 2, so that light emitted to the light shielding layer 51 can be absorbed as much as possible.
Preferably, the light shielding layer 51 is located on the surface of the reflective sheet 5 away from the light guide plate 2.
In order to ensure the light-emitting rate of the light guide plate 2, it is more preferable to dispose the light shielding layer 51 on the surface of the reflective layer away from the light guide plate 2, so that the reflective performance of the reflective sheet 5 can be maintained, and thus a part of light emitted to the light shielding layer 51 is reflected to the light guide plate 2, and a part of light is absorbed, so that the light can be prevented from being emitted from the light guide plate 2 of the non-display area 12 to the array substrate 70 of the display area 11 on the premise of ensuring the light-emitting rate of the light guide plate 2, and poor display can be avoided.
In addition, the light shielding layer 51 may be provided on both surfaces of the reflective sheet 5 close to and far from the light guide plate 2 according to actual circumstances.
Preferably, at least part of the reflective sheet 5 is disposed on a side of the light source 3 away from the back plate 4.
As shown in fig. 5, that is, the light source 3 is also covered by the reflective sheet 5, so that the light emitted from the light source 3 can be prevented from being emitted to the array substrate 70 of the display area 11, and the display defect can be avoided.
Preferably, the backlight module 10 of the present embodiment further includes: and the rubber frame 6 is at least partially positioned on one side of the reflecting sheet 5 far away from the back plate 4.
The rubber frame 6 is used for matching with the back plate 4 to arrange the light guide plate 2, the light source 3 and the reflecting sheet 5. Further, the plastic frame 6 may also be used to prevent light emitted from the non-display region 12 of the light source 3 or the light guide plate 2 from being directed to the array substrate 70 of the display region 11.
It should be noted that, as shown in fig. 5, the back plate 4 of the present embodiment further has side plates to form a receiving cavity for receiving the structures such as the light guide plate 2, the light source 3, and the reflective sheet 5. The light guide plate 2 and the back plate 4 are further provided with a reflection plate (not shown).

The display device further includes an array substrate 70 disposed at one side of the backlight module 10, and the backlight module 10 is used for providing the light source 3 to the array substrate 70.
The backlight module 10 of the display device of the embodiment has the reflective sheet 5, the reflective sheet 5 is provided with the light shielding layer 51, the light shielding layer 51 can absorb the light emitted to the reflective sheet 5, that is, if the light emitted from the light guide plate 2 of the non-display area 12 is emitted to the light shielding layer 51 of the reflective sheet 5, the light can be absorbed by the light shielding layer 51, so as to avoid the light from being emitted to the array substrate 70 of the display area 11, further avoid the display defect (for example, the brightness at the position corresponding to the light source 3 is greater than the brightness at the other positions, which shows the glowworm phenomenon), and ensure the display performance of the display device having the backlight module 10
