[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] A light source is often provided in a display device, especially in some liquid crystal display devices, which provide backlight for the display panel to achieve the purpose of displaying the picture on the panel. In the actual use of existing display panels, the display panel often needs to be assembled with a backlight module and a mounting shell to form a display device. The display device is often required to illuminate other locations outside the display panel. For example, when using a notebook computer, when there is a power outage indoors or the lights cannot be turned on to avoid disturbing others' rest, the user urgently needs to perform a large amount of keyboard input. The traditional notebook display panel itself has a small lighting range and limited lighting brightness, which cannot well meet the user's lighting needs for the keyboard area. The only option is to increase the brightness of the display panel, which requires increasing the energy consumption of the display panel. Moreover, excessive brightness can easily cause discomfort to the user's eyes.

[0042] In order to solve the technical problem that the existing display panel has an effective lighting effect outside the panel area but cannot provide effective lighting to positions outside the panel area, the main purpose of this application is to provide a display device and electronic equipment that can effectively illuminate the outside of the panel area using light emitted by a light source within the display panel.

[0043] refer to Figure 1-Figure 5 As shown, according to one aspect of the present application, a display device is provided, including a display panel 100 and a backlight module 200, wherein the display panel 100 includes a panel 10, and the backlight module 200 includes an optical film 20, a light guide plate 30, a back plate 40, a plastic frame 50 and a light source 60, wherein the panel 10, the optical film 20, and the light guide plate 30 are stacked in sequence, the plastic frame 50 is arranged on the peripheral side of the panel 10, the plastic frame 50 is fixedly connected to the back plate 40, and the light source 60 is arranged at Between the back panel 40 and the light guide plate 30, the plastic frame 50 is provided with a light guide channel 51, and the light guide channel 51 includes a first opening 511. The light guide plate 30 includes a first light guide portion 31 and a second light guide portion 32. The first light guide portion 31 is arranged corresponding to the position of the optical film 20. The second light guide portion 32 is arranged in the light guide channel 51, and one end of the second light guide portion 32 is connected to the first light guide portion 31, and the other end of the second light guide portion 32 guides light to the outside of the panel 10 through the first opening 511.

[0044] The light source 60 meets the lighting requirements of the optical film 20 and the panel 10 in the display panel 100 through the first light guide portion 31. The light generated by the light source 60 is guided through the second light guide portion 32 and the light guide channel 51 opened in the plastic frame 50 from the first opening 511 to the outside of the panel 10 through the second light guide portion 32, thereby meeting the lighting requirements of the target area outside the panel 10 area, improving the utilization rate of the light emitted by the light source 60, and completing the lighting of a specific area without adding external lighting equipment, thereby improving the flexibility of users in using the display device.

[0045] The first opening 511 of the plastic frame 50 can be set, for example, at the screen frame of a notebook computer, along the extension direction of the keyboard 13, so that the first opening 511 extends along the extension direction of the keyboard 13, thereby increasing the lighting area of the first opening 511, effectively improving the user experience when using the notebook keyboard 13 in a dark environment.

[0046] In one example, in a positive projection perpendicular to the panel 10, the light source 60 can be arranged between the plastic frame 50 and the back plate 40, and can be arranged in the peripheral area of the panel 10. A portion of the light emitted by the light source 60 is transmitted through the first light guide portion 31 of the light guide plate 30 to the panel 10 and the optical film 20 area under the display area of the panel 10. Another portion of the light emitted by the light source 60, that is, the loss light that cannot be utilized by the first light guide portion 31, can be transmitted through the second light guide portion 32 through the light guide channel 51 and the first opening 511 to the outside of the panel 10, thereby improving the utilization efficiency of the light from the original light source 60, and the lighting requirements of the equipment outside the panel 10 can be met without adding external lighting equipment.

[0047] According to one embodiment of the present application, the light guide plate 30 includes a bending portion 33, which is arranged between the first light guide portion 31 and the second light guide portion 32. The bending portion 33 has multiple bending angles. The bending portion 33 and the back plate 40 enclose a limited cavity 11. The light source 60 is arranged in the limited cavity 11. The light from the light source 60 is reflected by the multiple bending angles and then transmitted to the first light guide portion 31 and / or the second light guide portion 32. In actual use, the intensity of the light incident on the first light guide portion 31 and the second light guide portion 32 by the light source 60 can be increased by limiting the angle of the bending angle. For example, after changing the angle of the bending angle, the light intensity of the light source 60 on the first light guide portion 31 is increased, and the light intensity on the second light guide portion 32 is reduced. Thus, on the basis of meeting the light demand of the display panel 100 during daily use, the light demand on the outside of the panel 10 is met through the second light guide portion 32.

[0048] As an example, in the orthographic projection perpendicular to the panel 10, in the prior art, considering the overall volume and thickness of the display device, it is necessary to set the light source 60 at the edge of the panel 10, that is, a separate cavity is set between the plastic frame 50 and the back plate 40, and the cavity is set on the outside of the panel 10. Then, in order to improve the uniformity of the light used by the light source 60 in the display area of the panel 10, the light of the light source 60 will be guided from the non-display area at the edge of the panel 10 to the display area in the middle of the panel 10 through the light guide plate 30 to meet the lighting needs of the panel 10 and the optical film 20 in the display area.

[0049] In this embodiment, a limiting cavity 11 is formed by the bending portion 33 and the back plate 40, and a light source 60 is arranged in the limiting cavity 11. The light source 60 is electrically connected to the wiring 14 arranged on the back plate 40, and a fixing glue 15 is provided between the wiring 14 and the first light guide portion 31 for connection and fixation. In the cross-sectional view perpendicular to the orthographic projection of the panel 10, the limiting cavity 11 is away from the edge of the panel 10, and the limiting cavity 11 is connected to the light guide channel 51. The light source 60 guides light into the first light guide portion 31 and the second light guide portion 32 through the bending portion 33. Since the bending portion 33 has multiple bending angles, it also has multiple light reflection surfaces. The angle adjustment of the multiple bending angles adjusts the amount of light incident on the first guide portion and the second guide portion after passing through the multiple reflection surfaces, thereby achieving the purpose of illuminating the outside of the panel 10 area without changing the layout of the existing light source 60 relative to the display panel 100 and the backlight module 200.

[0050] In actual use, the position of the light guide channel 51 can be set according to actual lighting habits to adjust the position of the first opening 511 to meet different lighting needs of users.

[0051] refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, according to one embodiment of the present application, the bending portion 33 has a first bending portion 331 and a second bending portion 332, a first bending angle 34 is provided between the first bending portion 331 and the first light guide portion 31, a second bending angle 35 is formed between the second bending portion 332 and the second light guide portion 32, a third bending angle 36 is provided between the first bending portion 331 and the second bending portion 332, and the light source 60 is arranged in a limiting cavity 11 surrounded by the first bending portion 331, the second bending portion 332 and the back panel 40, the cross-sectional area of the bending portion 33 at the first bending angle 34 is S1, the cross-sectional area of the bending portion 33 at the second bending angle 35 is S2, and the cross-sectional area of the bending portion 33 at the third bending angle 36 is S3, wherein S1≥S2≥S3.

[0052] By adjusting the cross-sectional area S1 of the bend portion 33 at the first bend corner 34, the cross-sectional area S2 of the bend portion 33 at the second bend corner 35, and the cross-sectional area S3 of the bend portion 33 at the third bend corner 36, the effective light guiding area of the light in the light guiding portion can be controlled. For example, when S3 = 1 / 2S2 = 1 / 3S1, the third bend corner 36 can effectively limit the amount of light guided from the light source 60 from the bend portion 33 to the second light guiding portion 32, so that most of the light from the light source 60 is guided through the first light guiding portion 31 to the display area of the panel 10, thereby meeting daily lighting needs.

[0053] At the same time, since the cross-sectional area of the bending portion 33 at the third bending angle 36 is smaller, the loss of the bending portion 33 itself during the propagation of light can be relatively reduced. Since the cross-sectional area S2 of the bending portion 33 at the second bending angle 35 is larger than the cross-sectional area S3 of the bending portion 33 at the third bending angle 36, the light guiding efficiency from the bending portion 33 to the second light guiding portion 32 can be effectively increased, and the illumination and illumination range of the light at the first opening 511 can also be relatively improved.

[0054] refer to Figure 1-Figure 5 As shown, according to one embodiment of the present application, it also includes a first shell 70 and a second shell 80, the first shell 70 and the second shell 80 are detachably fixed, the first shell 70 and the second shell 80 form a accommodating cavity 90, the display panel 100 and the backlight module 200 are assembled and arranged in the accommodating cavity 90, the first shell 70 faces the panel 10, and the second shell 80 faces the back plate 40, the first shell 70 is provided with a second opening 71, the second opening 71 corresponds to the position of the first opening 511, and one end of the second light guide portion 32 extends from the first opening 511 to the second opening 71.

[0055] In this embodiment, the first shell 70 and the second shell 80 form a box structure. The first shell 70 and the second shell 80 enclose an accommodating cavity 90 for protecting the display panel 100 and the backlight module 200 .

[0056] As an example, in actual use, the first shell 70 and the second shell 80 can correspond to the face shell of a notebook, such as setting the first shell 70 as the B shell of the notebook, and setting the second shell 80 as the A shell of the notebook. The first shell 70 is provided with a third opening (not marked in the figure) and the display area of the display panel 100 faces the third opening, wherein the second opening 71 in the first shell 70 is provided on the side facing the keyboard 13, and the first opening 511 of the plastic frame 50 is provided corresponding to the second opening 71. Furthermore, the light from the light source 60 can be guided along the light guiding channel 51, the first opening 511 and the second opening 71 to the outside of the panel 10 through the second light guiding portion 32, thereby satisfying the user's purpose of illuminating the outer components of the panel 10.

[0057] According to one embodiment of the present application, the first housing 70 includes a cover plate 72, which is detachably mounted on the second opening 71, so that the second opening 71 can be opened or closed by the cover plate 72. Furthermore, the cover plate 72 can achieve the purpose of lighting by opening the second opening 71, and preventing the light from the light source 60 from being guided outward through the second light guide portion 32 by closing the second opening 71, thereby improving the flexibility of the user during use.

[0058] As an example, the cover plate 72 is rotatably assembled on the first housing 70 at one side of the second opening 71 to improve the convenience of the user during use.

[0059] According to one embodiment of the present application, the cover plate 72 includes a light-shielding surface 721 facing the second opening 71, and the light-shielding surface 721 is provided with a reflective member 12. The reflective member 12 can be configured as a reflective coating or reflective paper. The reflective member 12 located at the light-shielding surface 721 reflects light directed from the second light guide portion 32 to the second opening 71 back to the second light guide portion 32 after the cover plate 72 closes the second opening 71. The light is then reflected back to the first light guide portion 31 through the bent portion 33, thereby reducing light loss from the light source 60 and enhancing the illumination intensity of the display area of the panel 10.

[0060] According to one embodiment of the present application, the light guide plate 30 includes a first light guide surface 37 facing the panel 10 and a second light guide surface 38 facing the back plate 40. A reflector 12 is provided between the second light guide surface 38 and the back plate 40. Light from the light source 60 is transmitted to the optical film 20 through the first light guide surface 37. The presence of the reflector 12 between the second light guide surface 38 and the back plate 40 further reduces light loss from the light source 60, thereby improving the utilization efficiency of the light source 60.

[0061] In another embodiment, a reflective coating or reflective paper is provided on the side of the light guide channel 51 facing the second light guide portion 32 to prevent light loss caused by the light emitted by the light source 60 being absorbed by the material of the plastic frame 50, further improving the utilization efficiency of the light source 60 and reducing light energy loss.

[0062] In one embodiment, the light guide plate 30 is made of a flexible light guide material, the first light guide portion 31 can be supported between the back plate 40 and the display panel 100, the second light guide portion 32 is fixed by the light guide channel 51, and the bending portion 33 is shaped by the light source 60 in the limiting cavity 11 and the plastic frame 50 structure in the non-display area of the panel 10.

[0063] In one example, a plurality of serrated outer surfaces may be provided on the side of the bending portion 33 facing the light source 60. Then, the serrated outer surfaces may be used to improve the amount of reflected light at a plurality of bending angles, and the transmission path of the reflected light within the bending portion 33 may be fine-tuned to improve the precise adjustment of the light intensity of the first light guide portion 31 and the second light guide portion 32.

[0064] In one embodiment, the back plate 40 includes a first support plate 41 and a second support plate 42. The first support plate 41 is supported on the first light guide portion 31, and at least a portion of the second support plate 42 is supported on the second light guide portion 32. The plastic frame 50 defines a fixing groove 52 that communicates with the light guide channel 51. The second support plate 42 is disposed in the fixing groove 52, and at least a portion of the second support plate 42 abuts against the second light guide portion 32.

[0065] The first support plate 41 improves the limiting effect on the first light guide portion 31, while the second support plate 42 improves the limiting effect on the second light guide portion 32, thereby improving the overall stability of the light intensity at the location of the first opening 511. Specifically, because the light guide plate 30 is made of a flexible light-guiding material, the second support plate 42 improves the support of the second light guide portion 32 near one end of the limiting cavity 11, restricting the position of the second light guide portion 32 relative to the light guide channel 51, and improving the limiting effect on the light propagation path within the second light guide portion 32, thereby maintaining stable light intensity at the location of the first opening 511.

[0066] refer to Figure 2 As shown, within the orthographic projection plane of the panel 10, the non-display area, the plastic frame 50, the edge clamp 16, the reflector 12, the first light guide portion 31, the cable 14, and the first support plate 41 are sequentially stacked. The light source 60 within the limiting cavity 11 and the stacked structure of the non-display area of the panel 10 shape the bent portion 33 to improve the precise adjustment of the light intensity of the first light guide portion 31 and the second light guide portion 32. The edge clamp 16 can be configured as the same metal plate structure as the back panel 40, and the material and size of the edge clamp 16 can be flexibly adjusted according to actual usage requirements.

[0067] According to another aspect of the present application, an electronic device is provided, including a display device and a keyboard 13 , wherein the first opening 511 faces the keyboard 13 .

[0068] refer to Figure 7 and Figure 8As shown, in a dark room environment, a traditional notebook only relies on screen light to provide illumination for the keyboard 13. The first shell 70 and the second shell 80 of the notebook using the display device in the above embodiment can correspond to the face shell of the notebook, such as setting the first shell 70 as the B shell of the notebook and setting the second shell 80 as the A shell of the notebook. The first shell 70 is provided with a third opening (not shown in the figure). The display area of the display panel 100 faces the third opening, wherein the second opening 71 in the first shell 70 is provided on the side facing the keyboard 13, and the first opening 511 and the second opening 71 of the plastic frame 50 are provided correspondingly. Furthermore, the light of the light source 60 can be guided to the outside of the panel 10 along the light guiding channel 51, the first opening 511 and the second opening 71 through the second light guiding portion 32, so as to meet the user's purpose of illuminating the keyboard 13 outside the panel 10 and provide more illumination to the keyboard 13. This is a liquid crystal module structure that can increase the illumination of the notebook keyboard 13.

[0069] A light guide plate 30 with a bent portion 33 can be used. By guiding part of the light emitted by the LED light source 60 along the bent portion 33 of the light guide plate 30 toward the first light guide portion 31 and the second light guide portion 32, a long strip of lighting area can be formed directly in front of the notebook. After opening the cover 72 of the light source 60, the notebook keyboard 13 area will be illuminated.

[0070] Compared with the prior art, the notebook provided by this application has the following beneficial effects:

[0071] First, the light originally lost in the backlight module 200 is used to provide illumination for the notebook keyboard 13, thereby not increasing the power consumption of the notebook LCD module, not adding extra power consumption, and being energy-saving and environmentally friendly;

[0072] Secondly, to allow more light to reach the keyboard 13 area of the notebook, by adjusting the size and structure of the light guide plate 30, a portion of the light originally providing energy to the liquid crystal module can be guided through the second light guide portion 32 and the bending area, and converted into lighting light for the keyboard 13 area.

[0073] Third, when the user uses it in a dark environment, the operation is very simple. The user only needs to remove the cover 72 on the first shell 70. The light source 60 can be turned on or off by opening and closing the cover 72. The operation is simple.

[0074] Fourthly, the cover 72 can be personalized and shaped with patterns or shapes to enhance the personalization of the notebook and increase its appeal.
