Description

Technical Field

[0001] This invention relates to the field of displays, and more specifically to a display module and a display device. Background Technology

[0002] In recent years, to reduce the power consumption of OLED (Organic Light-Emitting Diode) display panels and improve display efficiency, geometric optics has been used to converge the relatively diffuse light emitted by the display panel to the top by setting up MLP (Micro Lens Pattern) technology, thereby improving display efficiency. However, MLP usually requires an IJP (Ink Jet Printing) process to form a planarization layer to increase flatness for subsequent processes. IJP requires setting up a barrier around the display module in advance to block the flow of ink. At the same time, since there is a ramp area at the edge of the IJP printed film layer, the ramp area will affect the display effect of the normal display area, making it impossible for MLP technology, especially the bottom bezel, to achieve a narrow bezel. Therefore, how to design the barrier and control the position of the IJP ramp area has become the key to a narrow bezel.

[0003] Therefore, there is an urgent need for a display module and display device to solve the above-mentioned technical problems. Summary of the Invention

[0032] In recent years, to reduce the power consumption of OLED (Organic Light-Emitting Diode) display panels and improve display efficiency, geometric optics has been used to converge the relatively diffuse light emitted by the display panel to the top by setting up MLP (Micro Lens Pattern) technology, thereby improving display efficiency. However, MLP usually requires an IJP (Ink Jet Printing) process to form a planarization layer to increase flatness for subsequent processes. IJP requires setting up a barrier around the display module in advance to block the flow of ink. At the same time, since there is a ramp area at the edge of the IJP printed film layer, the ramp area will affect the display effect of the normal display area, making it impossible for MLP technology, especially the bottom bezel, to achieve a narrow bezel. Therefore, how to design the barrier and control the position of the IJP ramp area has become the key to a narrow bezel.

[0033] Please see Figures 1 to 10 This invention provides a display module 100, comprising:

[0034] The display panel 200 includes a display function part 210, a binding part 230 corresponding to the display function part 210, and a bending part 220 located between the display function part 210 and the binding part 230;

[0035] A microlens layer 300 is located on one side of the display panel 200. The microlens layer 300 includes a first layer 400 and a second layer 500 located between the first layer 400 and the display panel 200.

[0036] The second layer 500 includes a plurality of first vias 510 and a plurality of second vias 520. Each first via 510 corresponds to the display function part 210, and each second via 520 corresponds to the bending part 220 or the binding part 230.

[0037] The present invention forms a plurality of second vias in the second layer corresponding to the bonding portion or bending portion. The second vias slow down the flow of ink and at the same time help to limit the sloping portion of the edge of the first layer to the side away from the display function portion, thereby reducing the impact of the sloping area on the normal display area and improving the display effect.

[0038] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0039] In this embodiment, please refer to Figure 1 The display module 100 includes a display panel 200 and a microlens layer 300 located on one side of the display panel 200. The display panel 200 includes a display function part 210, a bonding part 230 corresponding to the display function part 210, and a bending part 220 located between the display function part 210 and the bonding part 230. The microlens layer 300 includes a first layer 400 and a second layer 500 located between the first layer 400 and the display panel 200. The second layer 500 includes a plurality of first vias 510 and a plurality of second vias 520. Each first via 510 corresponds to the display function part 210, and each second via 520 corresponds to the bending part 220 or the bonding part 230.

[0040] The refractive index of the second layer 500 is greater than that of the first layer 400. The first via 510 of the second layer 500 corresponds to the display function part 210. Together with the first layer 400, they form a microlens structure, which enhances the light-gathering effect and improves the display effect. The second via 520 corresponds to the bending part 220 or the bonding part 230. The second via 520 can slow down the flow of material when the first layer 400 is formed, so as to avoid ink overflow when the first layer 400 is formed. At the same time, the second via 520 is located at the end away from the display function part 210, which is more conducive to keeping the ramp part 410 of the first layer 400 away from the display function part 210, avoiding the impact of the ramp area on the normal display area A, and improving the display effect.

[0041] In some embodiments, please refer to Figures 1 to 3 The first end of the first layer 400, on the side away from the display function unit 210, includes a ramp portion 410 and a flat portion 420, the flat portion 420 being located on the side of the ramp portion 410 closer to the display function unit 210; wherein, please refer to Figure 1 Each of the second through holes 520 corresponds to the bend 220, and the ramp 410 corresponds to the bend 220; or, please refer to Figure 2 Each of the second through holes 520 corresponds to the binding portion 230, and the climbing portion 410 corresponds to the bending portion 220; or, please refer to Figure 3 Each of the second through holes 520 corresponds to the binding part 230, and the climbing part 410 corresponds to the binding part 230.

[0042] During the fabrication of the display module 100, the bending portion 220, the bonding portion 230, and the display function portion 210 are all on the same plane. Therefore, when forming the first layer 400 of the microlens layer 300, when encountering the second via 520, the second via 520 is located on the side of the bending portion 220 away from the display function portion 210. Each second via 520 corresponds to the bending portion 220, which can reduce the bending stress of the display module 100 in the bending area E. Each second via 520 corresponds to the bonding portion 230, which maximizes the distance of the ramp portion 410 from the display function portion 210 in the normal display area A. The ramp portion 410 can be formed at the position corresponding to the bonding portion 230 or the bending portion 220, thereby avoiding the influence of the ramp area on the normal display area A and improving the display effect.

[0043] In some embodiments, please refer to Figure 6 The second layer 500 includes at least a first hole group 501 and a second hole group 502, the second hole group 502 being located on the side of the first hole group 501 away from the center of the display panel 200; wherein, both the first hole group 501 and the second hole group 502 include a plurality of second vias 520.

[0044] The second via 520 forms a hole group. When the first layer 400 is formed, the second layer 500 includes at least two hole groups to effectively block the ink material of the first layer 400 and prevent the ink material from overflowing the boundary.

[0045] In some embodiments, please refer to Figure 7 Each of the second through holes 520 in the first hole group 501 and / or the second hole group 502 is continuously provided.

[0046] The second through-hole 520 in any hole group is continuously provided to form a continuous slit to effectively block the ink material of the first layer 400 and prevent the ink material from overflowing the boundary.

[0047] In some embodiments, the first hole group 501 and / or the second hole group 502 are linear or curved.

[0048] Straight-line perforation groups are more regular and easier to form, while curved perforation groups can provide more complex blocking routes, which can more effectively block the ink material of the first layer 400 and prevent the ink material from overflowing the boundary. At the same time, the more complex blocking routes also help to reduce the width of the ramp 410, prevent the ramp 410 from encroaching on the display function section 210, reduce the impact of the ramp area on the normal display area A, and improve the display effect.

[0049] In some embodiments, please refer to Figures 8 to 10 The second through holes 520 in the first hole group 501 and / or the second hole group 502 are spaced apart.

[0050] The second via 520, which is spaced apart, increases the complexity of the manufacturing process, but also increases the complexity of the blocking path. This can more effectively block the ink material of the first layer 400 and prevent the ink material from overflowing the boundary. At the same time, the more complex blocking path also helps to reduce the width of the ramp portion 410, prevent the ramp portion 410 from intruding into the display function portion 210, reduce the impact of the ramp area on the normal display area A, and improve the display effect.

[0051] In some embodiments, please refer to Figure 9 , Figure 10 The opening shape of each of the second vias 520 is any one of circular, elliptical, or rectangular.

[0052] The opening shape of the second via 520 also contributes to the complexity of the blocking path. Combinations of different opening types can further increase the complexity of the blocking path. At the same time, circles and ellipses have a larger area than rectangles for the same perimeter, and can hold more ink volume. The curved opening edge is also conducive to conforming to the surface shape of the ink. By utilizing the surface tension of the liquid, the ink material of the first layer 400 can be blocked more effectively, preventing the ink material from overflowing the boundary. At the same time, a more complex blocking path is also conducive to reducing the width of the ramp 410, preventing the ramp 410 from intruding into the display function part 210, reducing the impact of the ramp area on the normal display area A, and improving the display effect.

[0053] In some embodiments, please refer to Figure 4 , Figure 5 The display module 100 further includes a protective layer 600, which is located on the side of the microlens layer 300 away from the display panel 200. The protective layer 600 includes a first portion 610 corresponding to the bent portion 220.

[0054] The protective layer 600 can protect the bent portion 220, and the first portion 610 corresponds to the bent portion 220. Preferably, the ramp portion 410 corresponds to the binding portion 230, the flat portion 420 corresponds to the bent portion 220, and the first portion 610 corresponds to the flat portion 420. This facilitates the coating formation of the first portion 610, makes the thickness of the first portion 610 more uniform, helps to disperse bending stress, and better protects the bent portion 220.

[0055] In some embodiments, the second through hole 520 corresponds to the bend 220, and the protective layer 600 can better fill the second through hole 520 and the flattening ramp 410.

[0056] In some embodiments, the material of the protective layer 600 may be a UV-curable adhesive.

[0057] In some embodiments, the first portion 610 conforms to the following formula: YM1×THK1+YM2×THK2=α×YM2; where YM1 is the Young's modulus of the first layer 400, THK1 is the thickness of the first layer 400, YM2 is the Young's modulus of the first portion 610, THK2 is the average thickness of the first portion 610, and α is the characteristic thickness.

[0058] Compared to existing technologies, where UV-curable adhesives directly contact the bonding portion 230, in this application, after the edges of the first layer 400 and the second layer 500 are extended outward, the film layer on the bending portion 220 changes from the existing single UV-curable adhesive to a stack of the protective layer 600 and the first layer 400. To ensure that the metal traces in the bending portion 220 are always in the neutral layer position, the average thickness THK2 of the first portion 610 is limited and needs to conform to the above formula. Generally, the characteristic thickness α can be the thickness of the existing single UV-curable adhesive.

[0059] For example, YM1 is typically 0.233 GPa; THK1 is typically 25 μm to 30 μm; YM2 is typically 0.5 GPa; and α is typically 80 μm. According to the equivalent modulus calculation formula, the film thickness of THK2 can be calculated to be 66.02 μm to 68.35 μm, and typically, its film thickness range can be defined as 65 μm to 70 μm.

[0060] In some embodiments, please refer to Figure 6The first punch-hole group 501 and the second punch-hole group 502 are both disposed at the edges corresponding to the display panel 200. The display module 100 includes a display area A and a non-display area B located around the display area A. The first punch-hole group 501 and the second punch-hole group 502 are located within the non-display area B. The non-display area B includes two functional positioning areas C, which are disposed on the side near the bending portion 220. The two functional positioning areas C are correspondingly disposed, and the first punch-hole group 501 and the second punch-hole group 502 are located outside the functional positioning areas C.

[0061] In some embodiments, please refer to Figure 6 The non-display area B also includes a bending area E and a binding area F. The bending area E corresponds to the bending portion 220, and the binding area F corresponds to the binding portion 230.

[0062] The functional positioning area C is used for positioning marks. The first hole group 501 and the second hole group 502 avoid this area to avoid affecting the alignment of subsequent processes.

[0063] In some embodiments, please refer to Figure 1 The display module 100 also includes a touch layer 700 located between the microlens layer 300 and the display function unit 210.

[0064] The depth of the first via 510 is less than the depth of the second via 520, and is blocked by the touch layer 700. The depth of the second via 520 is greater than the depth of the first via 510, which can effectively block the ink material of the first layer 400 and prevent the ink material from overflowing the boundary.

[0065] In some embodiments, please refer to Figure 1 The first layer 400 also includes a downhill section 430 located between the climbing section 410 and the flat section 420. The downhill section 430 is a normal phenomenon in the manufacturing process, and is generally short in width and has little impact.

[0066] In some embodiments, the film structure of the display panel 200 is not the focus of this application, and the display panel 200 may include an array substrate and a light-emitting device layer.

[0067] In some embodiments, the array substrate includes a substrate, an active layer on the substrate, a first insulating layer on the active layer, a gate layer on the first insulating layer, a second insulating layer on the gate layer, a source-drain layer on the second insulating layer, and a third insulating layer on the source-drain layer.

[0068] In some embodiments, the light-emitting device layer includes an anode layer on the third insulating layer, a light-emitting material layer on the anode layer, and a cathode layer on the light-emitting material layer. The display panel 200 further includes a pixel definition layer disposed on the same layer as the light-emitting material layer, a polarizing layer on the light-emitting device layer, and a flexible cover plate on the polarizing layer. The display panel 200 also includes a corresponding adhesive layer between the polarizing layer and the flexible cover plate.

[0069] In some embodiments, the light-emitting device layer may include OLED (Organic Light-Emitting Diode) material, or Micro LED or Mini LED, without specific limitations.

[0070] The present invention forms a plurality of second vias in the second layer corresponding to the bonding portion or bending portion. The second vias slow down the flow of ink and at the same time help to limit the sloping portion of the edge of the first layer to the side away from the display function portion, thereby reducing the impact of the sloping area on the normal display area and improving the display effect.

[0071] This invention also provides a method for manufacturing a display module 100, comprising:

[0072] S100, a display panel 200 is provided, including a display function part 210, a binding part 230 corresponding to the display function part 210, and a bending part 220 located between the display function part 210 and the binding part 230;

[0075] S400, A first layer 400 is formed on the second layer 500 to form a microlens layer 300.

[0076] The present invention forms a plurality of second vias in the second layer corresponding to the bonding portion or bending portion.
