Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device and display terminal. Background Technology

[0002] Current LCD displays are evolving from narrow bezels to bezel-less designs. Bezel-less LCD displays can provide a larger screen size within the same dimensions, enhancing their aesthetic appeal.

[0003] The bottom bezel of a liquid crystal display device has a binding area, which prevents a truly borderless effect. While a display device can achieve a three-sided borderless design, the bottom bezel is visually approximated by altering the appearance of the front bezel, making it appear similar to the other three sides of the display panel, thus achieving a near-four-sided borderless (4Borderless like, 4BL like) effect. In related technologies, the display device has a front bezel at the bottom bezel, which is fixed with screws, making assembly difficult and causing the front bezel to protrude from the display surface, resulting in poor visual appeal.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] According to the first aspect of this application, Figures 1 to 5As shown, a display device 1 is provided, including a backlight module 10, a display panel 20, and a front frame 30. The display panel 20 is disposed on the light-emitting surface side of the backlight module 10. The display panel 20 includes a first substrate 21 and a second substrate 22 facing each other. The first substrate 21 is disposed on the side of the second substrate 22 away from the backlight module 10. A first polarizer 23 is disposed on the side of the first substrate 21 away from the second substrate 22. The front frame 30 is disposed corresponding to one edge of the display panel 20. The front frame 30 includes a main body 31 and at least one engaging part 32. The main body 31 contacts the surface of the first substrate 21 away from the backlight module 10. The engaging part 32 is engaged with the side wall of the backlight module 10. The surface of the first polarizer 23 away from the first substrate 21 is flush with the surface of the main body 31 away from the backlight module 10.

[0048] The backlight module 10 provides a planar light source for the display panel 20, and the planar light source can be white light. The display panel 20 controls the light emitted by the backlight module 10 to achieve image display.

[0049] like Figure 5 As shown, the display panel 20 is a non-self-emissive display device such as a liquid crystal panel. The display panel 20 includes a display area AA and a non-display area NA disposed around the display area AA. The display area AA can be used to display images, and it has multiple sub-pixels 1a, such as red sub-pixels, green sub-pixels, and blue sub-pixels, thereby achieving color display. The non-display area NA may be equipped with a driving circuit, such as a gate driving circuit. The driving circuit is used to drive the sub-pixels 1a for display.

[0050] A liquid crystal layer is disposed between the first substrate 21 and the second substrate 22. The first substrate 21 and the second substrate 22 can be made of materials such as glass.

[0051] A first polarizer 23 is disposed on the upper surface of the first substrate 21. The area of ​​the first polarizer 23 is smaller than the area of ​​the upper surface of the first substrate 21, and the first polarizer 23 covers at least the display area AA. The upper surface of the first polarizer 23 is flush with the upper surface of the main body 31, improving the feel and visual effect at the lower bezel.

[0052] Specifically, the display panel 20 includes pixel electrodes, a common electrode, and a liquid crystal layer. Liquid crystal molecules in the liquid crystal layer are deflected in the electric field formed by the pixel electrodes and the common electrode. Liquid crystal molecules with different deflection angles have different light transmittance, thereby adjusting the brightness of the image. The display panel 20 also includes a color filter layer, which includes red, green, and blue color resists. Each color resist corresponds to one sub-pixel 1a. The red color resist allows red light to pass through, the green color resist allows green light to pass through, and the blue color resist allows blue light to pass through, thereby converting the white light emitted from the backlight module 10 into the corresponding colored light, achieving color display.

[0053] It should be noted that, as Figure 5 As shown, the display panel 20 typically needs to be connected to the bonding member 40, which can input control signals to the display panel 20. The connection method between the bonding member 40 and the display panel 20 can be a bonding connection, but is not limited to this. The bonding member 40 can be one or a combination of multiple of the following: a chip-on-film (COF) film 41, a driver IC, a flexible printed circuit board (FPC), and a printed circuit board assembly (PCBA).

[0054] Please see Figure 5 , Figure 5 This is a structural diagram of the display panel 20 and the binding member 40 in a flattened state. Figure 5 The following description uses the bonding component 40, which includes a flip-chip film 41 and a printed circuit board 42, as an example and should not be construed as limiting the scope of this application. The flip-chip film 41 is disposed between the display panel 20 and the printed circuit board 42, with one end connected to the display panel 20 and the other end connected to the printed circuit board 42. The number of flip-chip films 41 can be one or more. Figure 5 Six flip-chip films 41 are shown. The flip-chip films 41 are flexible and can be bent.

[0055] The front bezel 30 can correspond to the edge of the display panel 20 where the binding member 40 is located. Due to the presence of the binding member 40, the display device 1 cannot achieve a truly borderless bezel. However, by making the upper surface of the first polarizer 23 flush with the upper surface of the main body 31, the bezel on the side where the front bezel 30 is located can visually approximate the bezels of the other three sides of the display panel, thus achieving a near-borderless effect. The bezel width refers to the distance between the boundary line of the display area AA of any edge region of the display device 1 and the boundary line of the display device 1 itself.

[0056] like Figure 1 As shown, the binding member 40 is disposed on the lower frame, and the front frame 30 is also disposed on the lower frame. The width of the lower frame of the display device 1 is greater than the width of the other three sides, so that the other three sides can achieve a true borderless effect. The upper surface of the first polarizer 23 is flush with the upper surface of the main body 31, which can eliminate the gap between the display surface and the front frame 30, thereby enabling the lower frame to achieve an almost borderless effect.

[0057] In some embodiments, the front frame 30 may be made of a metal material, such as copper, iron, aluminum, etc., but is not limited thereto. The front frame 30 is a sheet metal part with a relatively uniform thickness, making it easy to process and form. The thickness of the front frame 30 may be less than or equal to 0.15 mm, thereby reducing the impact of the front frame 30 on the bezel width and the thickness of the display device 1.

[0058] The color of the front bezel 30 can match the color of the other three sides of the bezel. For example, the non-display area of ​​the display panel usually has a light-shielding layer, which can be black ink, etc. The color of the front bezel 30 can match the color of the light-shielding layer to further enhance the visual effect.

[0059] like Figure 2 As shown, the number of engaging portions 32 can be one or more. Increasing the number of engaging portions 32 improves the reliability of the engaging connection. Adjacent engaging portions 32 are spaced apart, and each engaging portion 32 engages with the side wall of the backlight module 10. The number of engaging portions 32 can be adjusted according to the length of the lower bezel of the display device, and is not limited here.

[0060] Please combine Figure 3A and Figure 3B The main body 31 of the front frame 30 is used to contact the upper surface of the display panel 20, and the engaging part 32 of the front frame 30 is used to engage with the side wall of the backlight module 10. The engaging connection assembly method is simple and convenient, which can improve the technical problem of difficult assembly and rework of the front frame 30.

[0061] Optionally, such as Figure 3A and Figure 3B As shown, a slot 10a is provided on the side wall of the backlight module 10. The engaging part 32 includes a connector 321 that contacts the side wall of the backlight module 10 and a hook 322 provided at the end of the connector 321 away from the main body 31. The hook 322 engages with the slot 10a.

[0062] like Figure 3B As shown, the number of card slots 10a is the same as the number of card hooks 322, and the positions of the card slots 10a correspond to the positions of the card hooks 322. Adjacent card slots 10a are spaced apart.

[0063] like Figure 3A and Figure 3B As shown, the connector 321 contacts the side wall of the backlight module 10. The side wall of the backlight module 10 can support and reinforce the engaging part 32, thereby improving the structural strength of the engaging part 32. At the same time, the contact between the connector 321 and the side wall of the backlight module 10 can also reduce the gap between the connector 321 and the backlight module 10, thereby reducing the width of the frame.

[0064] The hook 322 engages with the slot 10a on the side wall of the backlight module 10, thereby avoiding the engagement taking up extra space and avoiding increasing the bezel width.

[0065] Optionally, such as Figure 3A and Figure 4As shown, the hook 322 has a first surface 322a facing the connector 321, and the connector 321 has a second surface 321a facing the first surface 322a. The included angle A1 of the first surface 322a and the second surface 321a is less than or equal to 60 degrees.

[0066] By setting the angle of A1 to less than or equal to 60 degrees, the movement of the hook 322 in the direction parallel to the display surface and in the direction perpendicular to the display surface can be prevented, thus ensuring the stability of the assembly of the front frame 30.

[0067] In some embodiments, in order to achieve a snap-fit ​​connection and reduce the risk of the snap hook 322 slipping off after the snap-fit ​​connection, the length L4 of the snap hook 322 may be greater than or equal to 1.7 mm.

[0068] Optionally, such as Figure 3A As shown, the backlight module 10 includes a frame 11, which includes a first side wall 11a, a top wall 11b, and a first inclined surface 11c. The first side wall 11a is away from the center of the display device 1 and contacts the connector 321. The first side wall 11a is provided with a slot 10a. The top wall 11b of the frame 11 contacts the side surface of the main body 31 near the backlight module 10. The first inclined surface 11c connects the top wall 11b and the first side wall 11a. The first inclined surface 11c is parallel to the first surface 322a.

[0069] In some embodiments, such as Figure 3A As shown, the frame 11 can be made of plastic or similar materials. The frame 11 can be injection molded. The frame 11 has an internal space where the display panel 20 is housed. The internal space of the frame 11 also houses a light guide plate 12 and an optical film 13. The frame 11 also contains LED beads 14, which can be LEDs. The light-emitting surface of the LED beads 14 is positioned near the side wall of the light guide plate 12, which converts the light emitted from the LED beads 14 into a planar light source. The optical film 13 is used to uniformize the light and improve brightness.

[0070] like Figure 3A and Figure 4 As shown, the side wall of the frame 11 opposite to the center of the display device 1 is called the first side wall 11a, which corresponds to the lower frame of the display device 1. A slot 10a is provided on the first side wall 11a. The slot 10a does not completely penetrate the side wall of the frame 11, thereby enhancing the mechanical strength of the slot 10a area. The width L5 of the frame 11 corresponding to the slot 10a can be greater than or equal to 0.5 mm.

[0071] In some embodiments, such as Figure 3A and Figure 4As shown, the opening of the slot 10a needs to allow the hook 322 to slide in smoothly without affecting the structural strength of the frame 11. The distance L7 between the upper sidewall of the slot 10a and the first surface 322a of the hook 322 is greater than or equal to 0.15 mm, and the distance L8 between the lower sidewall of the slot 10a and the lower surface of the hook 322 is greater than or equal to 0.15 mm. The distance L10 between the bottom wall of the slot 10a and the end of the hook 322 is greater than or equal to 0.15 mm.

[0072] like Figure 3A and Figure 4 As shown, the top wall 11b of the frame 11 contacts the main body 31 and is used to support the main body 31. The width L1 of the top wall 11b of the frame 11 can be greater than or equal to 2 mm.

[0073] The first sidewall 11a is in contact with the connector 321 and the contact length L3 is greater than or equal to 2 mm.

[0074] The first inclined surface 11c connects the top wall 11b of the frame 11 to the first side wall 11a. The first inclined surface 11c is used to avoid the front frame 30, which facilitates the assembly of the front frame 30. This will be explained in conjunction with the assembly process of the front frame 30 later. In order to improve the avoidance effect of the first inclined surface 11c, the first inclined surface 11c can be made parallel to the first surface 322a.

[0075] Optionally, such as Figure 3A and Figure 4 As shown, the card slot 10a has a second sidewall 10b disposed on the side of the card slot 10a away from the connector 321, and the angle A2 between the second sidewall 10b and the adjacent first sidewall 11a is a right angle or an obtuse angle.

[0076] To facilitate the sliding of the hook 322 into the slot 10a during assembly, the angle of A2 can be minimized, ideally to a right angle. Increasing the angle of A2 reduces the accommodating space of the slot 10a while increasing its mechanical strength. To prevent interference between the second sidewall 10b and the hook 322, the angle of A2 can be increased to a maximum extent until the second sidewall 10b is parallel to the first surface 322a of the hook 322.

[0077] A2 and L8 need to be aligned with the angle of the first inclined plane 11c so that the hook 322 can slide into the slot 10a and engage with it.

[0078] Optionally, such as Figure 3C and Figure 5As shown, the display device 1 includes a binding member 40, which is disposed on the same side edge of the display panel 20 as the front frame 30, and is bound to the display panel 20. The first side wall 11a is provided with a relief groove 11d, and the binding member 40 passes through the relief groove 11d and bends to the side of the backlight module 10 away from the display panel 20. The relief groove 11d is disposed between two adjacent engaging portions 32.

[0079] like Figure 3C As shown, the first sidewall 11a is provided with a clearance groove 11d. The clearance groove 11d can avoid the flip-chip film 41, which bends along the sidewall of the backlight module 10 to the back side of the backlight module 10, and the printed circuit board 42 contacts the back side of the backlight module 10. With the above arrangement, the binding member 40 can be prevented from increasing the bezel width at the bottom edge.

[0080] Optionally, please combine Figure 3B , Figure 3C and Figure 5 , Figure 3B The cross-sectional position corresponds to the region between two adjacent flip-chip films 41, while Figure 3C The cross-sectional position corresponds to the region of the flip-chip film 41. The clearance groove 11d is provided between two adjacent engaging portions 32, and the clearance groove 11d is provided corresponding to the flip-chip film 41.

[0081] like Figure 3D As shown, the bonding member 40 includes a flip-chip film 41, which is disposed within the clearance groove 11d. The flip-chip film 41 includes a film body 411 and a driving chip 412 disposed on the side of the film body 411 near the clearance groove 11d. The depth of the clearance groove 11d corresponding to the driving chip 412 is greater than the depth of the clearance groove 11d corresponding to the film body 411.

[0082] The depth of the clearance groove 11d refers to the dimension of the clearance groove 11d in the direction perpendicular to the first sidewall 11a.

[0083] Since the driver chip 412 protrudes from the surface of the thin film body 411, a larger clearance space is required at the corresponding location of the driver chip 412. Therefore, the depth of the clearance groove 11d corresponding to the driver chip 412 can be greater than the depth of the clearance groove 11d corresponding to the thin film body 411, thereby avoiding interference between the sidewall of the frame 11 and the driver chip 412. At the same time, since the depth of the clearance groove 11d corresponding to the thin film body 411 is less than the depth of the clearance groove 11d corresponding to the driver chip 412, the mechanical strength of the sidewall of the frame 11 can be improved.

[0084] Combining 3C and Figure 3DThe clearance groove 11d corresponding to the driving chip 412 can penetrate through the side wall of the frame 11, and the depth of the clearance groove 11d corresponding to the thin film body 411 can be less than the thickness of the side wall of the frame 11.

[0085] Optionally, such as Figure 2 , Figure 3C As shown, the front frame 30 includes a protective part 33 corresponding to the flip-chip film 41. The protective part 33 is connected to the main body 31. The side surface of the protective part 33 facing away from the first sidewall 11a is flush with the side surface of the connector 321 facing away from the first sidewall 11a.

[0086] The protective part 33 can protect the flip-chip film 41 and prevent it from being damaged by external forces. The side surface of the protective part 33 opposite to the first sidewall 11a is flush with the side surface of the connector 321 opposite to the first sidewall 11a, thereby avoiding the addition of the protective part 33 to increase the width of the frame.

[0087] The number of protective parts 33 can be adjusted according to the number of flip-chip films 41, with one protective part 33 corresponding to one flip-chip film 41.

[0088] Optionally, such as Figure 3A As shown, the surface of the main body 31 near the backlight module 10 is in contact with the surface of the first substrate 21 away from the backlight module 10.

[0089] The lower surface of the main body 31 can contact the upper surface of the first substrate 21. In order to make the upper surface of the main body 31 flush with the upper surface of the first polarizer 23, the thickness of the main body 31 can be set to be equal to the thickness of the first polarizer 23. For example, the thickness of the first polarizer 23 and the thickness of the main body 31 are both 0.15 mm, but it is not limited to this.

[0090] Optionally, such as Figure 3A As shown, the display panel 20 includes a display area AA and a non-display area NA disposed around the display area AA, and the first polarizer 23 covers the display area AA.

[0091] Please refer to Figure 6 The assembly process flow diagram is provided to illustrate the assembly method of the front frame 30 in this application.

[0092] like Figure 6 As shown in (a), the display panel 20 and the backlight module 10 are assembled.

[0093] like Figure 6 As shown in (b), the front frame 30 is tilted upwards so that the hook 322 slides into the slot 10a. The main body 31 is close to the second inclined surface, which can avoid the main body 31, making it easier for the hook 322 to slide into the slot 10a.

[0094] like Figure 6 (c) and Figure 6 As shown in (d), the tilt angle of the front frame 30 is continuously reduced, causing the hook 322 to engage with the slot 10a. The main body 31 continuously approaches the top wall 11b of the frame 11, and the top wall 11b of the frame 11 limits the main body 31.

[0095] like Figure 6 As shown in (e), the main body 31 is brought into contact with the upper surface of the display panel 20 to complete the snap-fit ​​connection. The top wall 11b of the frame 11 supports the main body 31. The top wall 11b, the side walls of the frame 11, and the slot 10a limit the front frame 30 to prevent the front frame 30 from moving and ensure the stability of the front frame 30 assembly.

[0096] According to the second aspect of this application, such as Figure 7 As shown, a display terminal 2 is provided, which includes the display device 1 described above.

[0097] In this embodiment, as Figure 7 As shown, the display terminal 2 includes a display device 1 and a terminal body 3, which are combined into one unit.
