DETAILED DESCRIPTION
[0028] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0029] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

[0030] LCM (Liquid Crystal Module) liquid crystal displays have replaced traditional cathode ray tube displays with its many advantages such as clear and delicate images, no flicker, no eye damage, no radiation, low power consumption, and thinner and lighter, and are highly favored by users. Currently, they are widely used in electronic watches, mobile phones, tablets, handheld game consoles, learning machines, navigation devices, digital cameras, digital video cameras, computer monitors, and televisions. As display products tend to develop towards extremely narrow frames and thinness, it is found that the driving side (DP) of the display device is weak in strength and is prone to defects such as light leakage / fragmentation. Therefore, a display device with improved structural strength is urgently needed.
[0031] like Figure 1 As shown, it is a cross-sectional schematic diagram of a lower frame of a display device in the related art. The display device includes a display panel 1 and a backlight module 2 which are arranged relatively to each other and are connected by a rubber strip 3. When the frame of the display panel 1 is the same, when the lower frame of the display device is larger, a rubber frame 4 can be provided on the backlight module 2 to fill the remaining part of the display panel 1. In this way, when the display device mounting surface frame (B Bezel) is subjected to pressure in the thickness direction, the rubber frame 4 can disperse part of the pressure for the display panel 1, and there will be no risk of fragmentation.
[0032] However, due to the narrow frame design of the display device, such as Figure 2 As shown, there is no extra space to accommodate the glue frame 4 (the thinnest molding process requirement for the glue frame 4 is 0.35mm, and the minimum width requirement for gluing and fixing is 0.5mm). At this time, there is no mechanism on the outside of the display panel 1 to share the pressure of the surface frame. The bearing capacity of the display panel 1 on this side is relatively low, so light leakage / fragmentation is prone to occur.
[0033] In addition, as the frame becomes narrower, the optical film 2-1 is fixed on the bottom instead of the left and right sides. The existing backlight module 2 usually has an opening on the U-shaped structure 2-5 of the back plate 2-4, so that the optical film 2-1 extends to the opening and is connected and fixed to the display panel 1. However, this will weaken the strength of the area, and the bearing surface of the display panel 1 will be inconsistent, which is prone to corner breakage.
[0034] Below, through specific embodiments and combined Figures 3 to 10 To describe the technical solution of this application in detail.
[0035] In some embodiments of the present application, a display device is provided, such as Figure 3 and Figure 4 As shown, it includes a display panel 1 and a back panel 2-4 that are relatively arranged, one side of the display panel 1 is a driving side, and the other side is a non-driving side, and on the non-driving side, a rubber frame 4 is provided between the display panel 1 and the back panel 2-4; on the driving side, a support member 5 is provided between the display panel 1 and the back panel 2-4, and the support member 5 includes a connected substrate 5-1 and a first bending portion 5-2, the substrate 5-1 is located between the display panel 1 and the back panel 2-4, and the first bending portion 5-2 is bent in a direction close to the display panel 1.
[0036] like Figure 3 As shown, the display device includes a display panel 1 and a backlight module 2 which are arranged opposite to each other, and the top surface of the display panel 1 and the bottom surface of the back plate 2 - 4 of the backlight module 2 are connected and fixed by a rubber strip 3 .
[0037] like Fig.10 As shown, the lower side of the display panel 1 is a driving side, which is used to connect a printed circuit board 7, a driving chip, etc.; the left, right and upper sides of the display panel 1 are non-driving sides.
[0038] like Figure 4 As shown, a rubber frame 4 is provided between the display panel 1 on the non-driving side and the back panel 2-4, and no rubber frame 4 is provided between the display panel 1 on the driving side and the back panel 2-4. The material of the rubber frame 4 is, for example, thermosetting plastic, and is not specifically limited. Complex structural design can be achieved. The rubber frame 4 is used to support the display panel 1 and protect the backlight module 2. The display panel 1 and the rubber frame 4 can be connected by a rubber layer 9.
[0039] like Figure 3As shown, the display panel 1 on the driving side is provided with a support member 5, and the support member 5 includes a connected substrate 5-1 and a first bending portion 5-2, which can be an integrally formed structure. The substrate 5-1 is located between the display panel 1 and the backlight module 2, such as an iron plate or an aluminum plate; the first bending portion 5-2 is bent upward, and the end of the first bending portion 5-2 is against or provided with a gap with the rubber strip 3, so that a structure similar to a retaining wall is formed on the driving side of the display panel 1. By providing the support member 5, the bearing capacity of the display panel 1 on the driving side is improved, the squeezing force of the face frame can be shared, and the risk of light leakage / fragmentation of the display panel 1 is reduced.
[0040] The thickness of the support member 5 is 0.12mm to 0.2mm, for example 0.15mm, which has a higher design space utilization rate than the rubber frame 4 and is suitable for narrow-frame products; and the substrate 5-1 can make the bearing surface of the display panel 1 smoother, further reducing the light leakage / breakage rate; the first bent portion 5-2 and the substrate 5-1 can be perpendicular to each other, or there can be an inclination angle of ±10°, with no specific limitation; the first bent portion 5-2 can be set flush with the color film substrate 1-2, or there can be a gap of 0.1mm to 0.2mm with the rubber strip 3, providing installation capacity space.
[0041] The manufacturing method of the display device can first bend an iron piece / aluminum piece to form an L-shaped support piece 5, adhere the support piece 5 to the U-shaped structure 2 - 5 of the backlight module 2, and then assemble the display panel 1 to the support piece 5.
[0042] The display device has a simple structure and is easy to manufacture, and can effectively improve the bearing capacity of the display panel 1, ensure structural stability, and improve user experience.
[0043] In some embodiments, Figure 5 As shown, the substrate 5 - 1 is connected to a second bending portion 5 - 3 , the second bending portion 5 - 3 is bent in a direction away from the display panel 1 , and an end of the second bending portion 5 - 3 is abutted against or provided with a gap with the rubber strip 3 .
[0044] In the related art, for products with different frame sizes, different backlight modules 2 and plastic frames 4 need to be designed to adapt to each other. This process is long and costly, and is not conducive to rapid production.
[0045] like Figure 5As shown, in this embodiment, a second bending portion 5-3 is further connected to the substrate 5-1, and the second bending portion 5-3 is bent downward, so that the width of the backlight module 2 can be increased to adapt to a wider product frame; the end of the second bending portion 5-3 is abutted against the rubber strip 3 or a gap is set, and the gap length is 0.1mm to 0.2mm, providing installation capacity space; the second bending portion 5-3 can be close to the back panel 2-4, or it can be set at a distance from the back panel 2-4 to adapt to frames of different widths; without changing the back panel 2-4 rubber frame 4, the derivative frame change project can be quickly responded to, saving development time and related costs; the second bending portion 5-3 can be perpendicular to the substrate 5-1, or there can be a ±10° inclination angle, and there is no specific limitation.
[0046] In some embodiments, Figure 8 As shown, the first bending portion 5-2 is located in the middle of the driving side, and the second bending portion 5-3 is located at both ends of the driving side.
[0047] like Figure 8 As shown, the second bending portion 5-3 is set at both ends of the base plate 5-1 to adjust the width of the back plate 2-4 and improve stability; the first bending portion 5-2 is set in the middle of the base plate 5-1 to provide the surface frame bearing capacity.
[0048] In some embodiments, Figure 5 As shown, one end of the second bending portion 5-3 away from the substrate 5-1 is connected to the third bending portion 5-4, and the third bending portion 5-4 is bent in a direction close to the display panel 1, and the end of the third bending portion 5-4 is against or has a gap with the rubber strip 3.
[0049] like Figure 5 As shown, on the basis of setting the second bending portion 5-3, the third bending portion 5-4 can be connected, and the third bending portion 5-4 can be bent upward, which can not only increase the width of the backlight module 2, but also provide support for the face frame; the third bending portion 5-4 can be set flush with the color film substrate 1-2, or there can be a gap of 0.1mm to 0.2mm with the rubber strip 3 to provide installation capacity space; the third bending portion 5-4 and the substrate 5-1 can be perpendicular to each other, or there can be an inclination angle of ±10°, which is not specifically limited; the second bending portion 5-3 and the third bending portion 5-4 can offset each other, or they can be set at intervals to adapt to different frames.
[0050] In some embodiments, Figure 8 and Figure 3 As shown, the display panel 1 on the driving side is connected to a flexible circuit board 6, a first notch 5-5 is provided at the end of the first bending portion 5-2, the flexible circuit board 6 passes through the first notch 5-5 and is connected to the rubber strip 3, and a printed circuit board 7 is provided on the side of the flexible circuit board 6 away from the rubber strip 3.
[0051] like Figure 8 As shown, a first notch 5-5 is provided between the first bending portion 5-2 and the second bending portion 5-3 so that the flexible circuit board 6 and the like can pass through the support member 5. Figure 3 As shown, one end of the flexible circuit board 6 is connected to the display panel 1 , and the other end is connected to the rubber strip 3 . A printed circuit board 7 is provided on the side of the flexible circuit board 6 away from the rubber strip 3 , and a component 8 is provided on the side of the printed circuit board 7 away from the rubber strip 3 .
[0052] In some embodiments, Fig. 9 As shown, the backlight module 2 includes an optical film 2-1, a light guide layer 2-2, a lamp board 2-3 and a back panel 2-4 which are stacked in sequence. The cross section of the back panel 2-4 on the driving side along the thickness direction is a U-shaped structure 2-5. A second notch 2-6 is provided on the side of the U-shaped structure 2-5 close to the display panel 1. The optical film 2-1 extends into the second notch 2-6. The substrate 5-1 covers the U-shaped structure 2-5 and the second notch 2-6.
[0053] like Figure 3 As shown, the backlight module 2 includes a stacked optical film 2-1, a light guide layer 2-2, a lamp board 2-3 and a back plate 2-4. The back plate 2-4 is, for example, a metal plate with a thickness of, for example, 0.25 mm, which is not specifically limited. The back plate 2-4 is provided with a U-shaped structure 2-5, which wraps the optical film 2-1, the light guide layer 2-2 and the lamp board 2-3, and supports the display panel 1 to play a protective and supporting role; the lamp board 2-3 is, for example, an LED light-emitting board, provided with lamp beads 2-9; a reflective layer 2-8 is also provided between the light guide layer 2-2 and the back plate 2-4 for reflecting light; the optical film 2-1 includes, for example, a stacked uniform light layer, a first diffusion layer, a composite prism layer and a second diffusion layer for adjusting the light output to make the light irradiated to the display panel 1 more uniform and stable.
[0054] like Fig. 9 As shown, a second slot 2-6 is provided at the end of the U-shaped structure 2-5 so that the optical film 2-1 can extend into the second slot 2-6. By setting a substrate 5-1 to cover the second slot 2-6 and the U-shaped structure 2-5, the optical film 2-1 in the second slot 2-6 can be covered to avoid uneven steps, making the bearing surface of the display panel 1 more uniform and avoiding defective breakage.
[0055] In some embodiments, Fig. 9 As shown, the second notches 2-6 are located at two ends of the driving side, and the first notch 5-5 is located between the two second notches 2-6.
[0056] like Fig. 9As shown, the second notches 2-6 are located at both ends of the substrate 5-1, which has a good fixing effect on the optical film 2-1.
[0057] In some embodiments, Figure 6 As shown, the back plate 2 - 4 at the driving side is connected to a first support plate 2 - 7 , and the first support plate 2 - 7 abuts against a side of the printed circuit board 7 away from the flexible circuit board 6 .
[0058] like Figure 6 As shown, the back plate 2-4 is bent at the break to form a first support plate 2-7, and the first support plate 2-7 is against the side of the printed circuit board 7 away from the flexible circuit board 6, so that it can support the printed circuit board 7. However, due to the break, the display panel 1 is subjected to relatively uneven force, which increases the risk of fragmentation. In addition, the flexible circuit board 6 will expand and contract during the reliability test, and the load-bearing capacity at the break position is different from that at other positions, resulting in the outward deformation of the flexible circuit board 6 after the reliability test, which drives the lamp bead 2-9 to tilt, causing the picture at this position to leak light, affecting product quality.
[0059] In some embodiments, Figure 7 As shown, the substrate 5 - 1 is connected to a second support plate 5 - 6 , and the second support plate 5 - 6 abuts against a side of the printed circuit board 7 away from the flexible circuit board 6 .
[0060] like Figure 7 As shown, the support member 5 can also be bent to form a second support plate 5-6. The second support plate 5-6 is arranged parallel to the substrate 5-1. The second support plate 5-6 can be coplanar with the substrate 5-1. The second support plate 5-6 is arranged to abut against the side of the printed circuit board 7 away from the flexible circuit board 6. In this way, the printed circuit board can be supported. There is no need to set the first support plate 2-7 in the opening of the back plate 2-4. The structure has strong stability and avoids breakage / poor light leakage.
[0061] In some embodiments, Figure 3 As shown, the display panel 1 includes a first polarizing layer 1-1, a color filter substrate 1-2, an array substrate 1-3 and a second polarizing layer 1-4 which are stacked in sequence, the second polarizing layer 1-4 is arranged close to the backlight module 2, and the array substrate 1-3 and the backlight module 2 are connected by an adhesive layer 9.
[0062] The display panel 1 includes a first polarizing layer 1-1, a color film substrate 1-2, an array substrate 1-3 and a second polarizing layer 1-4 which are stacked in sequence to form a display image. The second polarizing layer 1-4 is spaced apart from the optical film 2-1, for example, by 0.05 mm, which is not limited to a specific interval. This can prevent the second polarizing layer 1-4 and the optical film 2-1 from being adsorbed against each other and affecting the light output effect.
