Description

Technical Field

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

[0002] To improve display quality, existing liquid crystal displays (LCDs) largely employ glass-based display solutions using micro light-emitting diodes (Micro LEDs) or mini light-emitting diodes (Mini LEDs). However, the fragility and low pressure resistance of glass substrates lead to low yield rates for large-size displays. Furthermore, the assembly of existing large-size Micro LED displays often involves splicing small glass substrate lamp panels onto a lightbox, requiring multiple assembly steps and increasing process complexity and cost. In addition, existing Micro LED displays typically use an aluminum substrate as a backplate, with the glass substrate lamp panels fixed to it using adhesive. The poor flatness of the aluminum substrate can create gaps between the glass substrate lamp panels and the substrate, allowing external moisture to penetrate the display device.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] To improve display quality, existing LCD display devices widely adopt Micro LED or Mini LED glass-based display solutions. However, the fragility and low pressure resistance of glass substrates lead to low yield rates for large-size displays. Furthermore, the assembly of existing large-size Micro LED displays often involves splicing small glass-based LED panels onto a lightbox, requiring multiple assembly steps and increasing process complexity and cost. In addition, existing Micro LED display devices typically use an aluminum substrate as a backplate, with the glass-based LED panels fixed to the aluminum substrate using adhesive. However, the poor flatness of the aluminum substrate can create gaps between the glass-based LED panels and the substrate, allowing external moisture to penetrate the display device.

[0021] Based on this, this application provides a display panel and a display device. The display panel can improve the crack resistance and pressure resistance of the glass substrate, effectively solving the defects of large-size glass substrates being fragile and having a low yield. It can also reduce the number of components to be assembled, effectively improve the assembly speed, and reduce the risk of moisture intrusion.

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-2 , Figure 1 This is a schematic diagram of the structure of the display panel provided in the first embodiment of this application; Figure 2 for Figure 1 The image shows a cross-sectional view of the display panel along line AA. This application provides a display panel 100 for displaying images; the display panel 100 may include a first glass substrate 1 and a plurality of glass substrate lamp panels 2.

[0024] Multiple glass-based lamp panels 2 are disposed on one side of the first glass substrate 1 and arranged in an array, together forming the light source of the display panel 100. Each glass-based lamp panel 2 includes a light-emitting area 10 and a welding area 20 surrounding the light-emitting area 10; it can be understood that on the multiple glass-based lamp panels 2 arranged in an array, the welding areas 20 of the multiple glass-based lamp panels 2 form a mesh area that intersects and is perpendicular to each other, so as to reserve the position of the welding structure 3.

[0025] The glass-based lamp panel 2 includes a second glass substrate 21 and a plurality of light-emitting units 22 disposed on the second glass substrate 21 corresponding to the light-emitting area 10. The second glass substrate 21 is used to support the plurality of light-emitting units 22, and as shown in the figure... Figure 1 As shown, multiple light-emitting units 22 are arranged in an array on the second glass substrate 21. The light-emitting units 22 can be micro-light-emitting diodes; specifically, the multiple light-emitting units 22 can include red, green, and blue sub-pixels, with adjacent sub-pixels of the three colors forming a pixel unit.

[0026] Each second glass substrate 21 is fixed to the first glass substrate 1 via a welding structure 3 to enhance the strength of the glass base lamp panel 2. Specifically, the projection of the welding structure 3 onto the second glass substrate 21 is located within the welding area 20, avoiding adverse effects on the circuitry of the light-emitting area 10 and the light-emitting unit 22 during welding. Specifically, femtosecond laser welding technology can be used to instantly fuse the glass at the welding position in the welding area 20 without damaging the original structure of the display device, thereby achieving the welding effect and forming the welding structure 3.

[0027] The welded structure 3 can be softened under laser irradiation of a preset power to release the weld between the first glass substrate 1 and the second glass substrate 21, allowing them to separate and facilitating rework. It is understood that the preset power of the laser used for desoldering is lower than the power used during laser welding; specifically, the preset power can be 25%-35% of the welding power to ensure that the welded structure 3 softens without directly vaporizing. Preferably, the preset power can be 30% of the welding power.

[0028] Thus, by laser welding the first glass substrate 1 and the second glass substrate 21 in the welding area 20 to form a welded structure 3, the crack resistance and pressure resistance of the glass substrate are improved, effectively solving the defects of large-size glass substrates being fragile and having a low yield, thereby realizing the fabrication of large-size glass-based lamp panels 2. Furthermore, compared to the existing method of assembling light boxes from small glass-based lamp panels 2 in large-size display devices, this application, by using the first glass substrate 1 as a supporting backplate and welding multiple large-size micro-LED glass-based lamp panels 2 to the first glass substrate 1, can also reduce the number of components required and effectively improve the assembly speed.

[0029] See Figure 2 In a specific embodiment, the second glass substrate 21 has a first surface 30 and a second surface 40 disposed opposite to each other; and a plurality of light-emitting units 22 are disposed on the first surface 30 of the second glass substrate 21; that is, the side of the second glass substrate 21 near the first surface 30 is the light-emitting side of the glass-based lamp panel 2, and the side of the second glass substrate 21 near the second surface 40 is the backlight side of the glass-based lamp panel 2.

[0030] The first glass substrate 1 is located on the side of the second glass substrate 21 facing the second surface 40; and the first glass substrate 1 and the second surface 40 of the second glass substrate 21 are bonded together and fixed by the welding structure 3. Specifically, the first glass substrate 1 is placed on the backlight side of the glass base lamp plate 2, and after the glass base lamp plate 2 is bonded to the surface of the first glass substrate 1, the welding area 20 of the first glass substrate 1 and the second glass substrate 21 is irradiated with a laser, thereby melting and solidifying the portion of the second glass substrate 21 near the gap and the portion of the first glass substrate 1 near the gap to form the welding structure 3.

[0031] Specifically, during laser welding, the laser can be focused on the gap between the second glass substrate 21 and the first glass substrate 1 so that the melting degree of the second glass substrate 21 and the first glass substrate 1 is similar, and the resulting welded structure 3 can be more uniform.

[0032] It is understandable that, compared with the existing technology that uses an aluminum substrate as a back plate, the embodiments of this application use a glass substrate with high flatness as a supporting back plate, which can also reduce the gap between the glass substrate lamp plate 2 and the back plate, and reduce the risk of external moisture intruding into the display panel 100.

[0033] like Figure 1 As shown, in a specific embodiment, each second glass substrate 21 can be fixed to the first glass substrate 1 by multiple welding structures 3, and the multiple welding structures 3 are spaced apart around the light-emitting area 10 to better fix the first glass substrate 1 and the second glass substrate 21. Specifically, each side edge of the second glass substrate 21 can have multiple spaced welding structures 3; preferably, the spacing between the multiple welding structures 3 can be the same to balance the forces between the first glass substrate 1 and the second glass substrate 21.

[0034] See Figures 3-4 , Figure 3 This is a schematic diagram of the structure of the display panel provided in the second embodiment of this application; Figure 4 for Figure 3 The diagram shows a cross-sectional view of the display panel along line BB. The structure of the display panel 100 provided in the second embodiment of this application is basically the same as that of the display panel 100 provided in the first embodiment of this application. The difference is that in the second embodiment of this application, the first glass substrate 1 is located on the side of the second glass substrate 21 facing the first surface 30, and the first glass substrate 1 and the first surface 30 of the second glass substrate 21 are spaced apart and fixed by the welding structure 3; that is, the first glass substrate 1 is disposed on the light-emitting side of the glass base lamp plate 2 and covers the light-emitting area 10 to protect the light-emitting unit 22 from mechanical damage.

[0035] Specifically, the first glass substrate 1 may be spaced apart from the side surface of the second glass substrate 21 on which the light-emitting units 22 are located, so as to avoid direct contact between the first glass substrate 1 and the light-emitting units 22, and to prevent the light-emitting units 22 from being damaged due to pressure.

[0036] The welding structure 3 is disposed in the gap between the first glass substrate 1 and the second glass substrate 21; and along the direction perpendicular to the glass base lamp plate 2, one end of the welding structure 3 is connected to the first glass substrate 1 and the other end is connected to the second glass substrate 21, so as to fix the first glass substrate 1 and the second glass substrate 21 while separating them, so that there is a gap between the first glass substrate 1 and the second glass substrate 21 sufficient to accommodate the light-emitting unit 22.

[0037] Welding filler materials, such as polyamide, epoxy resin, or unsaturated polyester resin, can be filled between the first glass substrate 1 and the second glass substrate 21. During laser welding, the laser is focused onto the welding filler material for irradiation, causing the material to melt and then solidify to form the welded structure 3.

[0038] Specifically, in the second embodiment of this application, the welding structure 3 can be a continuous annular structure surrounding the light-emitting area 10 to seal the light-emitting area 10 and form a sealed space, thereby isolating the multiple light-emitting units 22 located in the light-emitting area 10 from the outside world and preventing moisture from entering from the gap between the first glass substrate 1 and the second glass substrate 21.

[0039] See Figures 5-6 , Figure 5 This is a schematic diagram of the structure of the display panel provided in the third embodiment of this application; Figure 6 for Figure 5 The diagram shows a cross-sectional view of the display panel along line CC. The structure of the display panel 100 provided in the third embodiment of this application is basically the same as that of the display panel 100 provided in the first embodiment of this application. The difference is that in the third embodiment of this application, two adjacent second glass substrates 21 share a portion of the welding structure 3, thereby reducing the manufacturing cost by reducing the number of welding structures 3.

[0040] Specifically, the edges of two adjacent second glass substrates 21 are closely attached; the welding area 20 of one second glass substrate 21 near the edge of this side is welded and fixed to the first glass substrate 1 through the shared welding structure 3 of this part, and the welding area 20 of the other glass substrate near the edge of this side is also welded and fixed to the first glass substrate 1 through this shared welding structure 3.

[0041] The projection of the welding structure 3 located between two adjacent light-emitting areas 10 on the first glass substrate 1 coincides with the projection of the edges of the corresponding two second glass substrates 21 on the first glass substrate 1, so as to ensure that the two adjacent second glass substrates 21 can be welded and fixed to the first glass substrate 1 through the welding structure 3 located in the middle.

[0042] It should be noted that the coincidence of the projection of the welding structure 3 with the projection of the edges of the two second glass substrates 21 means that the projection of each welding structure 3 is at least partially located on the projection of the edge of the second glass substrate 21. Preferably, the central axis of the projection of each welding structure 3 coincides with the projection of the edges of two adjacent second glass substrates 21.

[0043] like Figure 5 As shown, the welding area 20 may further include a first welding area 201 located at the edge of the display panel 100 and a second welding area 202 located between two adjacent light-emitting areas 10; and the width of the second welding area 202 is smaller than the width of the first welding area 201, so as to reduce the area ratio of the welding area 20 in the display panel 100, thereby allowing the saved space to be used to set up the light-emitting unit 22 to increase the pixel density of the display panel 100.

[0044] In other words, the first welding areas 201 of multiple glass-based lamp panels 2 together form an annular area surrounding the display panel 100, while the second welding areas 202 of multiple glass-based lamp panels 2 together form a mesh area surrounding multiple light-emitting areas 10.

[0045] Each glass substrate lamp plate 2 located at the four top corners of the display panel 100 has two first welding areas 201 and two second welding areas 202. Specifically, in the four sides of each glass substrate lamp plate 2, the two first welding areas 201 are located on the two sides closer to the top corners of the display panel 100; while the two second welding areas 202 are located on the other two sides away from the top corners of the display panel 100.

[0046] Each glass substrate lamp plate 2 located on the four sides of the display panel 100 has a first welding area 201 and three second welding areas 202. Specifically, in each of the four sides of the glass substrate lamp plate 2, one first welding area 201 is located on one side closer to that side edge of the display panel 100; while the three second welding areas 202 are located on the other three sides away from that side edge of the display panel 100.

[0047] It is understood that in some other embodiments with a greater number of glass-based lamp panels 2, each glass-based lamp panel 2 located in the middle region of the display panel 100 has only four second welding areas 202; and the four second welding areas 202 surround the light-emitting area 10 of the glass-based lamp panel 2.

[0048] Specifically, the welding structure 3 located between two adjacent light-emitting areas 10 spans the corresponding two adjacent second welding areas 202. That is, the projection of the welding structure 3 located between two adjacent light-emitting areas 10 on the first glass substrate 1 is located within the projection of the corresponding two second welding areas 202 on the first glass substrate 1, and part of the projection of each welding structure 3 is located within one of the second welding areas 202, while another part of the projection is located within the other second welding area 202, so as to ensure that both adjacent second glass substrates 21 can be welded and fixed to the first glass substrate 1 through the welding structure 3 located in the middle.

[0049] In a specific embodiment, the width 'a' of the first welding area 201 is greater than or equal to 200 micrometers to reserve sufficient space to accommodate the welding structure 3 and avoid adverse effects on the circuitry and light-emitting unit 22 of the light-emitting area 10 during welding. Specifically, the width 'a' of the first welding area 201 can be 200 micrometers, 220 micrometers, 240 micrometers, 260 micrometers, or 300 micrometers.

[0050] The width b of the second welding area 202 is greater than or equal to 100 micrometers. This allows sufficient space to be reserved between two adjacent light-emitting areas 10 to accommodate the welding structure 3, while reducing the area ratio of the welding area 20 in the display panel 100. This allows the saved space to be used for setting up the light-emitting unit 22, thereby increasing the pixel density of the display panel 100. Specifically, the width b of the first welding area 201 can be 100 micrometers, 120 micrometers, 140 micrometers, 160 micrometers, or 180 micrometers.

[0051] See Figures 7-8 , Figure 7 This is a schematic diagram of the structure of the display panel provided in the fourth embodiment of this application; Figure 8 for Figure 7 The diagram shows a cross-sectional view of the display panel along line DD. The structure of the display panel 100 provided in the fourth embodiment of this application is basically the same as that of the display panel 100 provided in the first embodiment of this application. The difference is that in the fourth embodiment of this application, one of the first glass substrate 1 and the second glass substrate 21 has a plurality of positioning protrusions 11, and the other has a plurality of positioning grooves 211 corresponding to the plurality of positioning protrusions 11, and the positioning protrusions 11 are embedded in the corresponding positioning grooves 211; so as to position and align the plurality of second glass substrates 21 with the first glass substrate 1 before laser welding.

[0052] The fourth embodiment of this application is explained by taking the example of a positioning protrusion 11 disposed on one side surface of the first glass substrate 1 and a positioning groove 211 disposed on the side surface of the second glass substrate 21 facing the first glass substrate 1.

[0053] Specifically, a positioning protrusion 11 is disposed on the side surface of the first glass substrate 1 facing the second glass substrate 21, and the positioning protrusion 11 extends from the surface of the first glass substrate 1 toward the second glass substrate 21. A positioning groove 211 extends from the surface of the second glass substrate 21 toward the direction away from the first glass substrate 1; and the height of the positioning protrusion 11 is less than the depth of the positioning groove 211, so that the positioning protrusion 11 can be completely embedded in the positioning groove 211, which facilitates the contact between the surface of the first glass substrate 1 and the surface of the second glass substrate 21.

[0054] Furthermore, the projections of the positioning protrusion 11 on the second glass substrate 21 and the positioning groove 211 on the second glass substrate 21 are located within the welding area 20 to avoid the positioning protrusion 11 and the positioning groove 211 affecting the light-emitting area 10. Specifically, the multiple positioning protrusions 11 and the multiple welding structures 3 are staggered to avoid positional conflicts between the positioning protrusions 11 and the welding structures 3 that could affect the fixing effect.

[0055] This application provides a display panel 100, which includes a first glass substrate 1 and a plurality of glass base lamp panels 2. The plurality of glass base lamp panels 2 are disposed on one side of the first glass substrate 1 and arranged in an array. Each glass base lamp panel 2 includes a light-emitting area 10 and a welding area 20 surrounding the light-emitting area 10. Each glass base lamp panel 2 includes a second glass substrate 21 and a plurality of light-emitting units 22 disposed on the second glass substrate 21 corresponding to the light-emitting area 10. The light-emitting units 22 are micro light-emitting diodes. Each second glass substrate 21 is fixed to the first glass substrate 1 by a welding structure 3, and the projection of the welding structure 3 on the second glass substrate 21 is located within the welding area 20. By laser welding the first glass substrate 1 and the second glass substrate 21 in the welding area 20 to form the welding structure 3, the crack resistance and pressure resistance of the glass substrate are improved, effectively solving the defects of large-size glass substrates being fragile and having a low yield, thereby realizing the fabrication of large-size glass base lamp panels 2. Meanwhile, compared to the existing large-size display devices that use small glass substrate lamp panels 2 to splice light boxes and then assemble the light boxes, this application uses a first glass substrate 1 as a support back plate and welds multiple large-size micro light-emitting diode glass substrate lamp panels 2 to the first glass substrate 1, which can reduce the number of assembly items and effectively improve the assembly speed.

[0056] See Figure 9 , Figure 9 This is a simplified structural diagram of a display panel 100 provided in one embodiment of this application. This application also provides a display device for displaying an image. This display device may include the display panel 100 described in any of the above embodiments.
