It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless it is specifically stated otherwise.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
Referring to fig. 2, fig. 2 is a schematic diagram of a film structure of the backlight module provided by the embodiment of the invention, the backlight module includes a flexible substrate 10, an optical component 30 attached to the flexible substrate 10, and a light source 20 fixed on a side of the flexible substrate facing away from the optical component, wherein light of the light source is emitted from a side of the light source 20 in fixed contact with the flexible substrate 10.
It can be understood that, in order to realize the bending of the backlight module, the light emitted by the light source 20 can enter the optical component through the flexible substrate 10 and finally be emitted from the light emitting surface of the backlight module, so as to light the display device, and the material of the flexible substrate 10 in the backlight module provided by the embodiment of the invention comprises polyimide capable of transmitting light or other flexible materials capable of transmitting light.
Optionally, referring to fig. 2, the optical component in the backlight module includes a light guide plate 30, where the light guide plate 30 can reflect, scatter and refract the light emitted from the light source 20, so as to convert the point light source or the strip light source into a surface light source with uniform brightness, and provide a better light emitting effect. The optical member may further include one or more of a diffusion film 40, a lower brightness enhancement film 50, and an upper brightness enhancement film 60 sequentially stacked on the light guide plate 30. The diffusion film 40 can atomize the outgoing light of the light guide plate 30, so that the outgoing light is more uniform; the refraction action of the lower light enhancement film 50 and the upper light enhancement film 60 can adjust the emergent light angle, so that the light is emitted vertically upwards, light collection is realized, and the performance of the backlight module is improved. The lower and upper prism films 50 and 60 in the embodiment of the present invention can be understood as an upper prism sheet and a lower prism sheet, and the micro prism structure on the surface of the prism sheet can refract light, adjust the angle of the light, and achieve the effect of brightness enhancement.
It should be noted that, in order to realize the flexible backlight module, each optical film layer stacked on the flexible substrate 10 may be made of a flexible material. The light guide plate 30 may be made of polycarbonate or other materials having flexible characteristics, which is not particularly limited in the embodiment of the present invention.
Optionally, the light source 20 comprises a light emitting diode (Light Emitting Diode, LED). LEDs are semiconductor devices that are excited in response to a current to generate light of various colors, and have characteristics of small size, energy saving, environmental protection, high brightness, long life, and low power consumption, as compared to conventional light emitting devices using filaments. Referring to fig. 3, fig. 3 is a schematic structural diagram of an LED device. The LED device comprises a p-n diode 1, a top conductive contact layer 11 and a bottom conductive contact layer 12, the p-n diode 1 comprising a p-type semiconductor layer 1a (i.e. a p-type doped layer), an active layer 1b (or being a quantum well layer, which may be a single quantum well layer) and an n-type semiconductor layer 1c (i.e. an n-type doped layer). After a voltage is applied to the top conductive contact layer 11 and the bottom conductive contact layer 12, electrons and holes recombine in the active layer 1b, and the excess energy is released as light. The p-n diode may be fabricated based on a group-two-six material or a group-three-five nitride material. A group two-six material such as zinc selenide (ZnSe), zinc oxide (ZnO), or the like, a group three-five nitride material such as gallium nitride (GaN), aluminum nitride (AlN), indium nitride (InN), indium gallium nitride (InGaN), gallium phosphide (GaP), aluminum indium gallium phosphide (AlInGaP), aluminum gallium arsenide (AlGaAs), or an alloy thereof. In conventional packaging of LEDs, a wafer (p-n diode) is usually packaged in an epoxy resin, and most of the light is emitted from the surface of the wafer, so that the light of the LED can be emitted from the side where the LED is fixedly connected to the flexible substrate by only adjusting the position of the light emitting surface of the wafer during packaging to enable the light emitting surface to be on the same side as the binding pins of the LED. The light source 20 may be a light emitting diode chip or other type of light emitting unit, which is not particularly limited in this embodiment.
Further, referring to fig. 4, fig. 4 is a schematic diagram of a backlight module according to an embodiment of the invention when the backlight module is bent. When the backlight module provided by the embodiment of the invention is bent, the light emitting surface of the light source 20 only needs to be bent at a small angle along the surface fixedly connected with the flexible substrate 10, a large angle gap is not generated between the light emitting surface and the flexible substrate 10 due to bending stress, the stability of the backlight module structure is good, meanwhile, the problem that the display panel is poor due to the fact that the light emitting surface of the light source 20 'is in gap with the optical component 30' when the conventional backlight module is bent can be avoided, and the performance reliability of the backlight module is improved.
Optionally, in an embodiment of the present invention, a transparent optical adhesive (not shown) is disposed between the flexible substrate 10 and the light guide plate 30. The optical transparent adhesive is a colorless transparent cementing material with light transmittance of more than 90%, has small light loss and does not influence the light-emitting efficiency of the backlight module. The light guide plate 30 is fixed on the flexible substrate 10 through the transparent optical cement, so that the firmness of bonding and fixing between the light guide plate 30 and the flexible substrate 10 can be ensured, and the stability of the backlight module is improved.
In the conventional common module structure, the LED is located between the flexible substrate 10 'and the optical component 30', and when the flexible substrate 10 'and the optical component 30' are bonded, the selected transparent optical adhesive needs to fill the gap between the film layers due to the light source 20, and in this process, the requirements on the adhesive performance and the optical performance of the transparent optical adhesive are higher. And the uneven thickness of the transparent optical cement coated between the film layers can also affect the light emitting effect of the light source 20, and has a certain influence on the light emitting performance of the backlight module, thereby causing the problem of poor picture display of the display panel. In the embodiment provided by the invention, since the light source 20 is positioned on one side of the flexible substrate 10 away from the light guide plate 30, the contact between the flexible substrate 10 and the light guide plate 30 is the contact between the film layers, the gap between the contact surfaces is uniform, and a good bonding effect can be achieved by adopting the conventional transparent optical adhesive. The shape, size, thickness, shape, etc. of the transparent optical adhesive are not particularly limited, and any transparent optical adhesive capable of fixing the light guide plate 30 and the flexible substrate 10 is within the scope of the present invention.
Furthermore, the diffusion film 40, the lower brightness enhancement film 50 and the upper brightness enhancement film 60 sequentially laminated on the flexible substrate 10 can be bonded and fixed by using an optical transparent adhesive, so that the optical films are prevented from being damaged due to relative movement and friction during the use of the backlight module or when being affected by vibration, the light emitting performance of the backlight module is affected, and the abnormal edge display in the display device is prevented.
Optionally, referring to fig. 5, fig. 5 is a schematic diagram of another film structure of the backlight module provided by the embodiment of the invention, where the flexible substrate 10 is a light guide plate 30, and the optical components include one or more of a diffusion film 40, a lower brightness enhancement film 50 and an upper brightness enhancement film 60. The light source 20 is directly fixed on the surface of one side of the light guide plate 30, which is away from the optical component, so that the light source 20 is in direct contact with the light guide plate 30, a layer of flexible substrate is not required to be additionally adhered to the backlight module, the thickness of the backlight module can be reduced while the light emitting effect is ensured, the thinning of the display panel is realized, and meanwhile, the material can be saved and the cost is reduced.
Optionally, referring to fig. 6, fig. 6 is a schematic diagram of a film structure of a backlight module according to an embodiment of the invention. In this embodiment, the flexible substrate 10 multiplexes the diffusion film 40, and the light source 20 is directly fixedly connected to the diffusion film 40. At this time, the optical member includes one or more of a lower brightness enhancement film 50 and an upper brightness enhancement film 60 laminated on the diffusion film 40. The thickness and weight of the backlight module can be reduced to meet the demand of the market for thinning the display panel.
In order to further achieve the light and thin display panel, referring to fig. 7, fig. 7 is a schematic diagram of a film structure of a backlight module according to an embodiment of the invention, in this embodiment, a flexible substrate 10 may directly multiplex a lower brightness enhancement film 50, at this time, a light source 20 is fixedly connected to the lower brightness enhancement film 50, and an optical component includes an upper brightness enhancement film 60 disposed on the lower brightness enhancement film 50. Since the light emitting surface of the light source 20 is in direct contact with the lower intensifying film 50, the light emitted by the light source 20 directly enters the lower intensifying film 50 and the upper intensifying film 60, and is refracted and then enters the display panel by the backlight module, so as to provide a backlight for the display panel. Meanwhile, the problems of multiple reflection, scattering and refraction of light rays in the transmission process and large energy loss can be avoided when the optical films are more.
Optionally, referring to fig. 8 and 9, fig. 8 is a schematic structural diagram of a backlight module according to an embodiment of the present invention, a plurality of concave portions 80 are disposed on the flexible substrate 10, the light sources 20 are located in the concave portions 80, and one concave portion 80 corresponds to one light source 20. It is also possible that one recess 80 accommodates a plurality of light sources 20, and only one recess 80 is exemplarily shown for one light source 20 in fig. 6. It should be noted that the light source 20 may be partially located in the recess 80, and further, the light source 20 may be entirely located in the recess 80. Because only contact fixation is carried out through a contact surface between the light source 20 and the flexible substrate 10, the light source 20 is arranged in the concave part 80, on one hand, the light source 20 can be further fixed in the concave part 80 by utilizing the accommodating space of the concave part 80, the stability of the backlight module structure is improved, and on the other hand, the light source 20 is positioned in the concave part 80, the space occupied by the light source 20 can be saved, the thickness of the backlight module is further reduced, and the thinning of the display panel is realized. In addition, the accommodating space of the recess 80 can also protect the light source 20 to a certain extent. Fig. 9 is a partial top view of the backlight module provided in fig. 8, where the concave portion 80 may be a rectangular groove, may be in other shapes, and the concave portion 80 may be arranged in an array, or may be arranged in other manners, which is not particularly limited according to the specific situation.
Optionally, referring to fig. 9 again, the backlight module provided in the embodiment of the invention further includes a driving circuit 70, where the driving circuit 70 is located on a surface of the flexible substrate 10 contacting the light source 20. It will be appreciated that the light source 20 further includes a solder tail (not shown) that is led from the interior of the light source 20 to the non-recessed area of the flexible substrate 10 when one of the recessed portions 80 corresponds to one of the light sources 20, and is electrically connected to the driving circuit 70 for driving the light source 20 to emit light, thereby lighting the display panel.
It should be noted that, when the LED light bar is selected as the light source 20, the recess 80 of the flexible substrate 10 may be a strip-shaped groove with a shape corresponding to the LED light bar, and the soldering leg and the wire of the LED light are located in the strip-shaped groove, and the soldering leg of the LED light bar is LED out from the groove and electrically connected with the driving circuit.
Optionally, referring to fig. 10, fig. 10 is a schematic structural diagram of a backlight module according to an embodiment of the invention. The backlight module provided by the embodiment of the invention further comprises a reflective membrane 90 arranged at one side of the light source 20 away from the flexible substrate 10. The reflective membrane 90 is located on the side of the light source 20 facing away from the flexible substrate 10. Most of the light emitted by the light source 20 enters the optical component and is emitted from the backlight module after being reflected, scattered and refracted to lighten the display panel, but part of the light emitted by the light source 20 cannot directly enter the optical component, and the light which does not enter the optical component is reflected to the optical component again under the action of the reflecting film 90, so that the loss of the light can be reduced, and the light emitting efficiency of the backlight module is improved. Further, when the backlight module has a high requirement on the brightness of the light source, the reflective film 90 may be a silver reflective film or a white reflective film, so as to improve the reflective effect of the reflective film on the light emitted by the light source 20, and may also coat a material with high reflectivity on the surface of the reflective film 90, so that the light can enter the optical component by total reflection on the surface of the reflective film 90, thereby improving the light utilization rate of the backlight module.
Optionally, referring to fig. 10, the backlight module further includes a supporting frame 100 surrounding the optical component and the flexible substrate 10. The supporting frame 100 can provide stable support for a TFT array substrate disposed above a backlight module structure, such as a liquid crystal display device, to maintain a gap width between the backlight module and the array substrate, and prevent the display panel from directly contacting with optical components in the backlight module, and scratching the optical components to cause poor display. Since the flexible substrate 10 is further provided with the driving circuit 70, the supporting frame 100 may be provided with an opening at a position corresponding to the driving circuit so that the driving circuit is connected with other structures.
Optionally, the backlight module provided by the embodiment of the invention may further include a light shielding tape (not shown). The shading adhesive tape can be used for bonding and fixing the supporting frame body and the optical component, and can also be used for bonding and fixing the display panel and the backlight module, so that the reliability of the performance of the backlight module and the display device and the stability of the whole structure can be further improved, and meanwhile, the yield of products can be improved and the light leakage risk of the products can be reduced due to the arrangement of the shading adhesive tape.
The embodiment of the invention also provides a display device, as shown in fig. 11, and fig. 11 is a schematic diagram of the display device according to the embodiment of the invention. Taking a liquid crystal display panel as an example, referring to fig. 12, fig. 12 is a cross-sectional view along A1-A2 in fig. 11, the display panel further includes a liquid crystal display device sequentially disposed on a backlight module, including a color film 101, a TFT array substrate 102, a liquid crystal encapsulation layer 103, and a liquid crystal molecular layer 104, where the backlight module is used to provide a backlight source for the liquid crystal display device to light a screen. The display device comprises the backlight module. The specific structure of the backlight module has been described in detail in the above embodiments, and will not be described herein again, however, the display device shown in fig. 11 is merely a schematic illustration, and the display device may be any electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, or an electronic book.
Because the display device provided by the embodiment of the invention comprises the backlight module provided by the invention, a gap is not generated between the light source and the optical component when the display device is bent, so that the problem of poor display of the display device is avoided, and the display performance and stability of the display device are improved when the display device is bent.
