Description

Technical Field

[0002] Liquid crystal display (LCD) modules are widely used in various display devices due to their advantages such as thinness, low power consumption, and no radiation. An LCD module consists of a backlight module and an LCD panel; the backlight module provides backlighting for the LCD panel. During the in-panel design of the LCD panel, silver paste points (AG points) are placed at diagonal positions on the ground side of the panel. This allows for static electricity discharge during the module assembly stage by grounding these silver paste points, thus providing anti-static protection.

[0003] The traditional grounding and conduction method involves attaching a conductive cloth to the ground side of the LCD panel and pressing it down to connect / conduct with the silver paste dots. However, assembling the conductive cloth requires both attaching and pressing processes, making the assembly process rather complicated. Utility Model Content

[0033] The following descriptions of the embodiments are with reference to the accompanying drawings, illustrating specific embodiments in which the present invention can be implemented. Directional terms used in this invention, such as [up], [down], [front], [back], [left], [right], [inner], [outer], [side], etc., are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of the present invention, and not for limiting the present invention. In the drawings, structurally similar units are denoted by the same reference numerals. In the drawings, the thickness of some layers and regions is exaggerated for clarity and ease of description. That is, the dimensions and thicknesses of each component shown in the drawings are arbitrary, but the present invention is not limited thereto.

[0034] Reference Figure 1 , Figure 1 This example illustrates a partial cross-sectional structural diagram of a display module. The display module includes a backlight module 10' and a display panel 20' disposed on the light-emitting side of the backlight module 10'. The backlight module 10' includes a back plate 11' and a frame 12' fixedly connected to the back plate 11'. In the in-plane design of the display panel 20', silver paste points (AG Points) are set at diagonal positions on the ground side of the display panel 20'. The silver paste points serve as static electricity discharge parts 23' so that during the module assembly stage, static electricity can be released by grounding the static electricity discharge parts 23', thereby achieving an anti-static protection function.

[0035] The traditional grounding and conduction scheme involves attaching a conductive cloth 40' to the ground side of the display panel 10'. After attachment, the conductive cloth 40' is pressed down to connect / conduct with the electrostatic discharge part 23' at one end. The other end of the conductive cloth 40' is connected / conducted with the metal part 12' on the backlight module 10' to achieve electrostatic protection. However, assembling the conductive cloth 40' requires both attachment and pressing processes, making the assembly process relatively complicated. Moreover, using the conductive cloth 40' also increases the cost of the display module.

[0036] Therefore, this utility model provides a display panel and a display device, with reference to Figures 2 to 9The display module 100 includes a backlight module 10, a display panel 20 disposed on the light-emitting side of the backlight module 10, and an electrostatic discharge member 30 fixedly connected to the backlight module 10. The display panel 20 includes an array substrate 21 and a color filter substrate 22 disposed opposite to each other. The color filter substrate 22 is recessed. A first protrusion 211 protruding relative to the color filter substrate 22 is formed on the array substrate 21. An electrostatic discharge portion 23 is disposed on the first protrusion 211. The electrostatic discharge member 30 includes a metal spring 31 located on the first protrusion 211 and abutting against the electrostatic discharge portion 23. In this way, by setting the metal spring 31 to abut against the electrostatic discharge portion 23 on the display panel 20, the metal spring 31 is easy to assemble without attaching or pressing. Moreover, the metal spring 31 can directly conduct the static electricity on the display panel 20 to the electrostatic discharge member 30, thereby eliminating the need to set a conductive cloth, saving the attaching and pressing process of assembling the conductive cloth, and improving the problem of the relatively troublesome assembly of the conductive cloth.

[0037] In some embodiments, please refer to Figures 2 to 5 , Figure 2 This is a schematic diagram of an overall structure of a display module provided in an embodiment of the present utility model. Figure 3 for Figure 2 A magnified structural diagram at point M. Figure 4 for Figure 2 A schematic diagram of the cross-sectional structure along the B-B' direction. Figure 5 for Figure 4 A magnified structural diagram at point N. The display module 100 includes a backlight module 10, a display panel 20 disposed on the light-emitting side of the backlight module 10, and an electrostatic discharge member 30 fixedly connected to the backlight module 10. The display panel 20 includes an array substrate 21 and a color filter substrate 22 disposed opposite to each other. The color filter substrate 22 is recessed, and a first protrusion 211 protruding relative to the color filter substrate 22 is formed on the array substrate 21. An electrostatic discharge portion 23 is disposed on the first protrusion 211. The electrostatic discharge member 30 includes a metal spring 31 located on the first protrusion 211 and abutting against the electrostatic discharge portion 23.

[0038] The backlight module 10 includes a back plate 11 and a frame 12. The back plate 11 includes a bottom 111 and a side 112. The side 112 forms a receiving cavity around the bottom 111. The frame 12 is fixedly connected to the side 112. The display panel 20 is disposed corresponding to the receiving cavity. Optionally, the back plate 11 is a metal back plate, such as an aluminum back plate.

[0039] The backlight module 10 also includes a light guide plate 13, a light source 14, etc. The light guide plate 13 and the light source 14 are disposed in the receiving cavity. The frame 12 cooperates with the back plate 11 to fix the light guide plate 13 and the light source 14 and other optical components in the receiving cavity.

[0040] The light source 14 is located on at least one side of the light guide plate 13, wherein the side of the light guide plate 13 is connected between the upper and lower surfaces of the light guide plate 13, the upper surface of the light guide plate 13 is the light emitting surface of the light guide plate 13, the lower surface of the light guide plate 13 is opposite to the upper surface, and the side of the light guide plate 13 opposite to the light source 14 is the light incident surface of the light guide plate 13. Optionally, the bottom 111 of the back plate 11 is provided with a recess at the position corresponding to the light source 14. The recess provides clearance space when assembling the light source 14 and can improve the overall strength of the back plate 11.

[0041] Of course, the backlight module 10 may also include other optical films such as a reflective sheet 15 disposed on the lower surface of the light guide plate 13 and a brightness enhancement film 16 disposed on the upper surface of the light guide plate 13. The reflective sheet 15 is used to reflect light leaking from the lower surface of the light guide plate 13 to improve light utilization. The brightness enhancement film 16 is used to increase the brightness of light emitted from the light guide plate 13.

[0042] The display panel 20 is disposed on the light-emitting side of the backlight module 10 and located above the receiving cavity, and is fixedly connected to the frame 12 of the backlight module 10. For example, the display panel 20 can be fixedly connected to the frame 12 of the backlight module 10 through an adhesive layer. The display panel 20 is a liquid crystal display panel 20, which includes a liquid crystal cell and a first polarizer 24 located on the bottom 111 side of the liquid crystal cell away from the back plate 11, that is, the first polarizer 24 is located on the light-emitting side of the liquid crystal cell.

[0043] The liquid crystal cell includes an array substrate 21 and a color filter substrate 22 disposed opposite to each other. Naturally, the display panel 20 also includes a liquid crystal layer disposed between the array substrate 21 and the color filter substrate 22, a sealing adhesive, and a second polarizer disposed on the side of the array substrate 21 away from the color filter substrate 22. The sealing adhesive surrounds the liquid crystal layer to seal it.

[0044] The color filter substrate 22 is located on the side of the array substrate 21 away from the backlight module 10. The color filter substrate 22 is recessed, and a first protrusion 211 is formed on the array substrate 21, protruding relative to the edge of the color filter substrate 22. The first protrusion 211 is the portion of the outer boundary of the array substrate 21 that extends beyond the outer boundary of the color filter substrate 22. In other words, the outer contour of the color filter substrate 22 is located within the outer contour of the array substrate 21 and is smaller than the outer contour of the array substrate 21. The first protrusion 211 is the portion of the array substrate 21 not covered by the color filter substrate 22.

[0045] The first polarizer 24 is recessed, and a second protrusion 221 is formed on the color filter substrate 22, protruding relative to the first polarizer 24. The second protrusion 221 is the portion of the outer boundary of the color filter substrate 22 that extends beyond the outer boundary of the first polarizer 24. In other words, the outer contour of the first polarizer 24 is located within the outer contour of the color filter substrate 22 and is smaller than the outer contour of the color filter substrate 22. The first protrusion 211 is the portion of the color filter substrate 22 that is not covered by the first polarizer 24.

[0046] For example, the display module 100 includes a display area and a border area located outside the display area. The first protrusion 211 and the second protrusion 221 are both located within the border area. The array substrate 21 has a plurality of sub-pixels arranged in an array corresponding to the display area. For example, each sub-pixel includes a pixel driving circuit and a first electrode. The pixel driving circuit is electrically connected to the first electrode to provide a driving signal to the first electrode.

[0047] The color filter substrate 22 includes a second electrode and a color filter layer. An electric field is formed between the second electrode and the first electrode to drive the liquid crystal molecules of the liquid crystal layer to deflect, thereby controlling the amount of backlight transmitted by the backlight module 10. However, the structure of the display panel 20 is not limited to this. For example, the second electrode and the color filter layer may also be disposed on the array substrate 21.

[0048] The color filter layer includes multiple color filter blocks of different colors and a black matrix located between adjacent color filter blocks. The different color filter blocks include red, green, and blue color filter blocks, and each color filter block corresponds to one sub-pixel. It should be noted that the description of the specific structure of the array substrate 21 and the color filter substrate 22 in this embodiment is only an example, and the present invention is not limited thereto. For example, the array substrate 21 of the present invention may also be provided with the second electrode, thereby eliminating the need to provide the second electrode on the color filter substrate 22.

[0049] The static discharge portion 23 is provided on the first protrusion 211 of the array substrate 21. Optionally, the static discharge portion 23 can be formed by applying silver paste to the first protrusion 211, and the static discharge portion 23 is also a silver paste dot formed on the first protrusion 211. Static electricity on the display panel 20 can accumulate on the static discharge portion 23 and be discharged to the static discharge member 30 through the static discharge portion 23.

[0050] The electrostatic discharge device 30 includes a metal spring 31 and a fixing part 32 connected to the metal spring 31. The metal spring 31 is disposed corresponding to the electrostatic discharge part 23 and the first protrusion 211, and abuts against the electrostatic discharge part 23. The abutment between the metal spring 31 and the electrostatic discharge part 23 means that the metal spring 31 and the electrostatic discharge part 23 are in interference contact, and there is an interaction force between the metal spring 31 and the electrostatic discharge part 23. The metal spring 31 is elastic and can deform under the force of the electrostatic discharge part 23, so as to ensure good contact and conductivity between the metal spring 31 and the electrostatic discharge part 23.

[0051] Optionally, in the thickness direction of the display module 100, the cross-sectional shape of the metal spring 31 is at least one of arc shape, wavy shape, etc. This embodiment uses an arc-shaped cross-sectional shape of the metal spring 31 as an example. Figure 5 As shown, the arc-shaped metal spring 31 has an arc-shaped convex surface and an arc-shaped concave surface opposite to the arc-shaped convex surface. The arc-shaped convex surface is close to the static discharge part 23 and abuts against the static discharge part 23 to increase the interaction force between the metal spring 31 and the static discharge part 23, thereby enhancing the reliability of the contact and conduction between the metal spring 31 and the static discharge part 23.

[0052] The fixing part 32 is fixedly connected to at least one of the frame 12 and the back plate 11 to fix the static discharge component 30, thereby ensuring good contact and conductivity between the metal spring 31 and the static discharge part 23. For example, in some embodiments, the fixing part 32 is fixedly connected to the frame 12; in some embodiments, the fixing part 32 is fixedly connected to the back plate 11; in other embodiments, the fixing part 32 is connected to both the frame 12 and the back plate 11.

[0053] Optionally, the fixing part 32 and the metal spring 31 are integrally formed, that is, the fixing part 32 and the metal spring 31 are integrally molded. The fixing part 32 and the metal spring 31 are made of the same material, such as galvanized steel sheet, stainless steel, etc., for example, electrolytic zinc-plated steel sheet (SECC), hot-dip galvanized steel sheet (SGCC), 55% aluminum-zinc alloy steel sheet (SGLC), etc.

[0054] Optionally, the fixing part 32 and the metal spring 31 have the same thickness. In this case, the thickness of the electrostatic discharge member 30 is uniform, for example, the thickness of the electrostatic discharge member 30 ranges from 0.1 mm to 0.3 mm, such as 0.1 mm, 0.12 mm, 0.15 mm, 0.17 mm, 0.19 mm, 0.2 mm, 0.22 mm, 0.25 mm, 0.27 mm, 0.29 mm, 0.3 mm, etc. By setting the metal spring 31 to a suitable thickness, the elasticity and rigidity of the metal spring 31 can be guaranteed, thereby improving the contact conductivity between the metal spring 31 and the electrostatic discharge part 23.

[0055] In some embodiments, the fixing part 32 includes a first sub-part 321 and a second sub-part 322. The first sub-part 321 connects the metal spring 31 and the second sub-part 322. The connection between the first sub-part 321 and the metal spring 31 has a first bending shape, and the connection between the first sub-part 321 and the second sub-part 322 has a second bending shape, which is different from the first bending shape. The bending shape refers to the degree of bending at the connection, such as the bending shape, bending angle, and bending radius.

[0056] For example, the bending shape at the connection between the first sub-part 321 and the metal spring 31 is arc-shaped, and the bending shape at the connection between the first sub-part 321 and the second sub-part 322 is L-shaped; or, for another example, the bending shapes at the connection between the first sub-part 321 and the metal spring 31 and the bending shapes at the connection between the first sub-part 321 and the second sub-part 322 are both arc-shaped, but the bending radii of the arcs are different, so that the first bending shape is different from the second bending shape.

[0057] In some embodiments, the bending degree at the connection between the first sub-part 321 and the metal spring 31 is less than the bending degree at the connection between the first sub-part 321 and the second sub-part 322. For example, the bending radius at the connection between the first sub-part 321 and the metal spring 31 is greater than the bending radius at the connection between the first sub-part 321 and the second sub-part 322, so as to reduce the area occupied by the second sub-part 322 and facilitate the realization of a narrow bezel.

[0058] Optionally, the area of ​​the second sub-part 322 is larger than the area of ​​the first sub-part 321. By setting the second sub-part 322 with a larger area, the overall area of ​​the static discharge member 30 can be increased, thereby improving the static discharge effect of the static discharge member 30.

[0059] In some embodiments, the second sub-part 322 is bent from the end of the first sub-part 321 toward the bottom 111 of the back plate 11, and the bending shape at the connection between the first sub-part 321 and the second sub-part 322 is L-shaped. The first sub-part 321 and / or the second sub-part 322 are fixedly connected to at least one of the frame 12 and the back plate 11 to fix the electrostatic discharge member 30 to the backlight module 10 and to ensure good contact and conduction between the metal spring 31 and the electrostatic discharge part 23.

[0060] In some embodiments, to further improve the contact conductivity between the metal spring 31 and the static discharge part 23, the surface heights of the frame 12 and the back plate 11 in the thickness direction of the display module 100 are both less than or equal to the surface height of the array substrate 21. Here, the "surface height" of a structure in this invention refers to the maximum vertical height of the structure relative to a specific reference plane, that is, the vertical distance between the top surface of the structure and the specific reference plane. For example, in this invention, the plane containing the bottom 111 of the back plate 11 is used as the reference plane. The surface height of the frame 12 refers to the maximum vertical height of the frame 12 relative to the bottom 111 of the back plate 11, that is, the vertical distance between the top surface of the frame 12 and the bottom 111 of the back plate 11. The top surface of the frame 12 refers to the surface of the frame 12 facing away from the bottom 111 of the back plate 11.

[0061] Accordingly, the surface height of the array substrate 21 refers to the maximum vertical height of the array substrate 21 relative to the bottom 111 of the back plate 11, that is, the vertical distance between the top surface of the array substrate 21 and the bottom 111 of the back plate 11. The top surface of the array substrate 21 refers to the surface of the array substrate 21 facing away from the bottom 111 of the back plate 11.

[0062] In some embodiments, please refer to Figures 6 to 9 , Figure 6 This is a schematic diagram of another overall structure of the display module 100 provided in an embodiment of the present utility model. Figure 7 for Figure 6 A magnified structural diagram at point P in the middle. Figure 8 for Figure 6 A schematic diagram of the cross-sectional structure along the C-C' direction. Figure 9 for Figure 8A magnified structural diagram at point Q. (Compared to...) Figure 2 The difference in the example display module 100 is that the second sub-part 322 of the electrostatic discharge member 30 is folded back from the end of the first sub-part 321 onto the second protrusion 221 and overlaps with the second protrusion 221. The first sub-part 321 is fixedly connected to at least one of the frame 12 and the back plate 11 to fix the electrostatic discharge member 30 to the backlight module 10.

[0063] By folding the second sub-part 322 back onto the first sub-part 322, the area of ​​the electrostatic discharge member 30 is increased while the space occupied by the electrostatic discharge member 30 is further reduced, thereby achieving a narrower bezel. The surface height of the second sub-part 322 can be basically flush with the surface height of the first polarizer 24. For example, the surface height of the second sub-part 322 may be slightly greater than or less than the surface height of the first polarizer 24, or the surface height of the second sub-part 322 may be flush with the surface height of the first polarizer 24, in order to reduce the visual difference caused by the step difference.

[0064] In this embodiment, the cross-sectional shape of the metal spring sheet 31 is wavy in the thickness direction of the display module 100. Other details are as described in the above embodiment and will not be repeated here.

[0065] In some embodiments, the present invention also provides a display device, which includes the display module 100 described in one of the above embodiments. The display device can be an electronic device with display function, such as a television, mobile phone, tablet computer, computer monitor, gaming device, wearable device, digital camera, car navigation system, electronic billboard, or ATM.

[0066] As can be seen from the above embodiments:

[0067] This utility model provides a display module and display device. The display module includes a backlight module, a display panel disposed on the light-emitting side of the backlight module, and an electrostatic discharge device fixedly connected to the backlight module. The display panel includes an array substrate and a color filter substrate disposed opposite to each other. The color filter substrate is recessed. A first protrusion is formed on the array substrate, protruding relative to the color filter substrate. An electrostatic discharge portion is disposed on the first protrusion. The electrostatic discharge device includes a metal spring located on the first protrusion and abutting against the electrostatic discharge portion. In this way, by setting the metal spring to abut against the electrostatic discharge portion on the display panel, the metal spring is easy to assemble, without the need for attachment and pressing. Moreover, the metal spring can directly conduct the static electricity on the display panel to the electrostatic discharge device, thereby eliminating the need for a conductive cloth, saving the attachment and pressing process of assembling the conductive cloth, and improving the problem of the relatively troublesome assembly of the conductive cloth.
