Description
Technical Field
The present invention relates to a light source module, and more particularly, to a light source module for a display device and a display device using the same.
Background
The liquid crystal display device comprises a liquid crystal display panel and a backlight module. Since the lcd panel itself does not emit light, the backlight module is required to provide a display light source to the lcd panel. Therefore, the main function of the backlight module is to provide a display light source with high luminance and high uniformity.
The backlight module can be conventionally divided into a side-in type backlight module and a direct type backlight module. Generally, the light source energy of the Light Emitting Diodes (LEDs) used in the direct-type backlight module is concentrated, so that bright spots are generated in the area directly above the LEDs on the display screen, resulting in uneven brightness of the entire screen.
The existing known solution is to make the arrangement of the light emitting diodes denser, i.e. to increase the number of the light emitting diodes, so that the bright spots can be further overlapped together, and the respective intensities of the bright spots are neutralized, thereby reducing the phenomenon of uneven brightness. However, when the number of the light emitting diodes is larger, the cost for manufacturing the backlight module is higher, and the backlight module cannot be widely applied to products.
The background section is provided to facilitate an understanding of the present disclosure, and thus the disclosure in the background section may include other art that is not known to those of skill in the art. Furthermore, the statements contained in the "background" section do not represent a representation of the claimed subject matter or the problems associated with one or more embodiments of the present disclosure, nor are they intended to be known or appreciated by those skilled in the art prior to the present disclosure.

In order to achieve one or a part of or all of the above or other objects, an embodiment of the invention provides a light source module including a substrate, a plurality of first rectangular light emitting elements, and a plurality of second rectangular light emitting elements. The substrate is provided with a side surface and a bearing surface, and the side surface is connected with the bearing surface. The plurality of first rectangular light-emitting elements are arranged on the bearing surface, and each first rectangular light-emitting element is provided with a first light-emitting side surface. The second rectangular light-emitting elements are arranged on the bearing surface. The first rectangular light-emitting elements and the second rectangular light-emitting elements are arranged in an array.

In the light source module of the embodiment of the invention, each of the second rectangular light emitting elements has a second light emitting side surface, and the second light emitting side surfaces are inclined relative to the side surface of the substrate, that is, the second rectangular light emitting elements arranged on the substrate are rotated, because the light path of the light emitting elements in the diagonal direction is long, a dark part area is easily formed, and after the second rectangular light emitting elements are rotated, the second light emitting side surfaces can face the dark part area in the diagonal direction, so that the brightness of the dark part area is increased, and the brightness uniformity of the light source module can be further improved.

Detailed Description
The foregoing and other features and advantages of the invention will be apparent from the following, more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are simply directions with reference to the drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
Fig. 1 is a schematic top view of a light source module according to an embodiment of the invention. Referring to fig. 1, a light source module 10 of the present embodiment includes a substrate 100, a plurality of first rectangular light emitting elements 200, and a plurality of second rectangular light emitting elements 300. The substrate 100 has a side surface 110 and a carrying surface 120, and the side surface 110 is connected to the carrying surface 120. The first rectangular light emitting elements 200 and the second rectangular light emitting elements 300 are disposed on the supporting surface 120, and the first rectangular light emitting elements 200 and the second rectangular light emitting elements 300 are arranged in an array, for example. In the present embodiment, each of the first rectangular light emitting elements 200 has a first light emitting side surface 210, and the first light emitting side surface 210 is, for example, parallel or perpendicular to the side surface 110 of the substrate 100, but not limited thereto. Each of the second rectangular light emitting elements 300 has a second light emitting side surface 310, and the second light emitting side surface 310 is relatively inclined to the side surface 110 of the substrate 100.
The difference between the first rectangular light emitting element 200 and the second rectangular light emitting element 300 is that the second light emitting side 310 of the second rectangular light emitting element 300 is relatively inclined to the side 110 of the substrate 100. In fig. 1, specifically, the first rectangular light emitting elements 200 and the second rectangular light emitting elements 300 are, for example, arranged on the carrying surface 120 in an array staggered with each other, but not limited thereto. It should be noted that the second light-emitting side surface 310 referred to in the present specification refers to any side surface of the second rectangular light-emitting device 300 capable of emitting light, i.e. the second rectangular light-emitting device 300 should have 4 second light-emitting side surfaces 310, and these side surfaces are, for example, inclined to the side surface 110 of the substrate 100. For convenience of description, the second light-emitting side 310 represents one of the side surfaces. The above description also applies to the first light emitting side 210 of the first rectangular light emitting element 200, and will not be repeated here.
In the present embodiment, the first rectangular light emitting device 200 and the second rectangular light emitting device 300 are, for example, but not limited to, square light emitting devices (as shown in fig. 1). Specifically, the square shape means that the orthogonal projection shapes of the first rectangular light emitting device 200 and the second rectangular light emitting device 300 on the supporting surface 120 are square. In addition, the second light emitting side surface 310 of each second rectangular light emitting element 300 is inclined at an angle θ 1 to the side surface 110, such as, but not limited to, 45 °. In other words, the folding angle a formed by connecting any two adjacent second light-emitting side surfaces 310 of each second rectangular light-emitting element 300 is aligned with the folding angle a of another second rectangular light-emitting element 300 along the alignment direction D, and the alignment direction D is, for example, parallel or perpendicular to the side surface 110 of the substrate 100. The bevel angle a is a turning point of the side structure of the second rectangular light emitting device 300, and taking a rectangle as an example, the side structure should have 4 turning points, that is, 4 bevel angles a. However, the present invention does not particularly limit the angle θ 1 of the second light emitting side 310 of the second rectangular light emitting element 300 with respect to the side 110. In other embodiments, when the second rectangular light emitting device 300 is, for example, a rectangular light emitting device (the orthographic projection shape on the supporting surface 120 is a rectangle), the angle θ 1 may be adjusted according to design requirements, or the angle θ 1 of the second light emitting side 310 relative to the side 110 may be different among a plurality of second rectangular light emitting devices 300.
The substrate 100 is, for example, a printed circuit board, which can be a hard board or a soft board, and is used for carrying the plurality of first rectangular light emitting elements 200 and the plurality of second rectangular light emitting elements 300, and driving the plurality of first rectangular light emitting elements 200 and the plurality of second rectangular light emitting elements 300 to emit light through the substrate 100. In the present embodiment, the shape of the substrate 100 is, for example, a rectangle, but is not limited thereto.
The first rectangular light emitting element 200 and the second rectangular light emitting element 300 may be light emitting diodes, but may be other types of light emitting elements. In addition, the first rectangular light emitting device 200 and the second rectangular light emitting device 300 can also be light emitting chips that are directly cut from a wafer and are not packaged, such as light emitting diode chips. For example, the led chip is, but not limited to, a die-level nitride led chip emitting blue light at a dominant wavelength. The number of the first rectangular light emitting elements 200 and the second rectangular light emitting elements 300 in fig. 1 is 8, but not limited thereto. It should be noted that fig. 1 is intended to show the arrangement of the plurality of first rectangular light emitting elements 200 and the plurality of second rectangular light emitting elements 300, the number of the plurality of first rectangular light emitting elements 200 and the plurality of second rectangular light emitting elements 300 is only an illustration, and the invention is not particularly limited.
According to different design requirements, the light source module 10 of the present embodiment further includes at least one optical film (not shown) disposed on one side of the substrate 100 having the carrying surface 120. The at least one optical film is, but not limited to, a brightness enhancement film, a diffuser film, a prism sheet, or a hybrid prism sheet.
In the light source module 10 of the present embodiment, each of the second rectangular light emitting elements 300 has a second light emitting side surface 310, and the second light emitting side surface 310 is inclined with respect to the side surface 110 of the substrate 100, that is, the second rectangular light emitting elements 300 disposed on the substrate 100 are rotated, since the light path of the light emitting elements in the diagonal direction is long, a dark area is easily formed, and after the second rectangular light emitting elements 300 are rotated, the second light emitting side surfaces 310 can face the dark area in the diagonal direction, so as to increase the brightness of the dark area, thereby further improving the brightness uniformity of the light source module 10. Compared to the known solutions, there is no need to increase the number of light-emitting elements, so that the production costs can be reduced.
Fig. 2A is a schematic top view of a light source module according to another embodiment of the invention. Fig. 2B is a schematic cross-sectional view of the reflective element disposed on the substrate. Referring to fig. 2A and 2B, the light source module 10a of the present embodiment has a similar structure and advantages to the light source module 10 described above, and only the main differences of the structure will be described below. The light source module 10a of the present embodiment further includes a reflective element 400 disposed on the supporting surface 120 (as shown in fig. 2B), and having a plurality of reflective grooves 410 and a plurality of openings 420. The reflective trough 410 is a groove formed by the reflective element 400 protruding upward from the supporting surface 120. Each opening 420 is disposed at the bottom of each reflective trough 410, and the first rectangular light emitting elements 200 and the second rectangular light emitting elements 300 are disposed through the openings 420. The reflective element 400 of the present embodiment is, for example, integrally formed, but not limited thereto. In another embodiment, the reflective element 400 can be formed by splicing several pieces of reflective elements.
Each of the reflective cavities 410 has four reflective side surfaces 411 connected to each other, for example, the reflective side surfaces 411 are relatively inclined to the supporting surface 120, and the maximum width W1 of the opening of the reflective cavity 410 is greater than the maximum width W2 of the bottom of the reflective cavity 410, so that the light emitted from the first rectangular light-emitting device 200 and the second rectangular light-emitting device 300 is guided out after being reflected by the reflective side surfaces 411. In the present embodiment, the folding angle a of each second rectangular light emitting element 300 corresponds to one of the four reflective side surfaces 411, for example, as shown in fig. 2A. Since the reflection function of the reflection groove 410 in the included angle region formed by connecting any two reflection side surfaces 411 is weaker than the reflection function of the reflection side surfaces 411, the light L1 emitted from the first light-emitting side surface 210 of the first rectangular light-emitting device 200 is emitted to the reflection side surfaces 411, and the second light-emitting side surface 310 of the second rectangular light-emitting device 300 corresponds to the included angle region of the reflection groove 410, so that the light L2 emitted from the second light-emitting side surface 310 can be directly emitted to the included angle region to compensate for the weaker reflection function of the included angle region, so that the uniformity of the whole light emission is more uniform, and the effect of improving the brightness uniformity is achieved.
Fig. 3 is a schematic top view of a light source module according to another embodiment of the invention. Referring to fig. 3, the light source module 10b of the present embodiment has similar structure and advantages to the light source module 10 described above, and the difference is that in the light source module 10b of the present embodiment, for example, the first light-emitting side 210 of each first rectangular light-emitting element 200 is relatively inclined to the side 110 of the substrate 100. In addition, the angle θ 1 of the second light emitting side surface 310 relative to the side surface 110 is the same as the angle θ 2 of the first light emitting side surface 210 relative to the side surface 110, for example, but is not limited thereto. The light source module 10b may also include the reflective element 400 in the light source module 10a, and the invention is not limited to the application of the combination of the elements in the embodiments. Since the light source module 10b of the present embodiment rotates the first rectangular light emitting elements 200 disposed on the substrate, the brightness uniformity can be further improved.
Fig. 4 is a schematic cross-sectional view of a display device according to an embodiment of the invention. Referring to fig. 4, the display device 1 of the present embodiment includes the light source module 10 and the display panel 20. The display panel 20 is disposed on the light emitting side of the light source module 10. The display panel 20 may be a liquid crystal display panel or other non-self-emissive display panel. The light source module 10 is used to provide a surface light source L3 to the display panel 20 as a display light source. This light source module 10 may be replaced with the light source module of any of the above embodiments. Since the light source module 10 of the display device 1 of the present embodiment can improve the brightness uniformity and reduce the production cost, the display device 1 using the light source module 10 can also improve the brightness uniformity and reduce the production cost.
In summary, in the light source module of the embodiments of the invention, each of the second rectangular light emitting elements has a second light emitting side surface, and the second light emitting side surface is relatively inclined to the side surface of the substrate, that is, the second rectangular light emitting elements disposed on the substrate are rotated, since the light path of the light emitting elements in the diagonal direction is long, a dark area is easily formed, and after the second rectangular light emitting elements are rotated, the second light emitting side surfaces can face the dark area in the diagonal direction, so as to increase the brightness of the dark area, thereby further improving the brightness uniformity of the light source module. Compared to the known solutions, there is no need to increase the number of light-emitting elements, so that the production costs can be reduced. The display device of the embodiment of the invention can also improve the brightness uniformity and reduce the production cost due to the use of the light source module.
However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made by the claims and the summary of the invention are still included in the scope of the present invention.
