[0040] In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0041] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0042] In view of the technical problem that the one-piece black debugging of the display module 10 is limited due to the characteristic that the hue of the black pressure-sensitive adhesive cannot be changed, the embodiment of the present disclosure proposes a display module 10, as Figures 1 to 19 shown, the display module 10 includes a display panel 100, a first black ink layer 200, a support structure layer 300 and / or an ultra-clean foam composite film 400, and an adhesive layer 500 and / or a pressure-sensitive adhesive layer 600. A base layer 110 is provided on the non-display side of the display panel 100; the first black ink layer 200 is disposed on the side of the base layer 110 away from the display side of the display panel 100; the support structure layer 300 and / or the ultra-clean foam composite film 400 are / is located on the side of the first black ink layer 200 away from the display panel 100; the adhesive layer 500 and / or the pressure-sensitive adhesive layer 600 are / is disposed between the first black ink layer 200 and the support structure layer 300 or the ultra-clean foam composite film 400.

[0043] In the display module 10 of the embodiment of the present disclosure, as Figures 2 to 19As shown, a first black ink layer 200 is provided on the side of the base layer 110 away from the display side of the display panel 100. The thickness of the first black ink layer 200 can be flexibly adjusted, so that the optical density and / or hue value of the first black ink layer 200 can be adjusted by adjusting the thickness of the first black ink layer 200. To a certain extent, the debugging range of the integrated black of the display module 10 can be expanded, and the integrated black value of the display module 10 can be made to be below 1.5, and even the integrated black value of the display module 10 can be made to be below 1.0, which can significantly improve the effect of the display module 10 achieving integrated black and enhance the user experience.

[0044] It should be noted that, as Figure 1 shown, the display module 10 includes an active area 12 (Active Area, VA) and an ink area 13 (black matrix, BM) provided at the edge of the active area 12. A visible area 11 (view area AA) is provided in the active area 12. When the display module 10 is in a non-display state, it is required that the display module 10 presents an integrated black effect, that is, the smaller the color difference between the active area 12 and the ink area 13 of the display panel 100, the better. In the embodiments of the present disclosure, the integrated black value refers to the color difference between the active area 12 and the ink area 13. Optionally, the calculation formula of the integrated black value is:

[0045] ΔE a*b* = SQRT[(L1* - L2*) 2 + (a1* - a2*) 2 + (b1* - b2*) 2

[0046] In the above formula, ΔE a*b* is the color difference between the active area 12 and the ink area 13, SQRT is the square root, (L1*, a1*, b1*) is the color measurement value of the active area 12, and (L2*, a2*, b2*) is the color measurement value of the ink area 13. In the color measurement value, L represents the brightness value, and its value is between 0 and 100; a* represents the range from red to green, a* is green when it is negative, and a* is red when it is positive, b* represents the range from yellow to blue, b* is blue when it is negative, and b* is yellow when it is positive. In some embodiments of the present disclosure, the display panel 100 may be an organic light-emitting diode (organic light-emitting diode, OLED) display panel 100. The display panel 100 further includes a pixel layer 120 provided on the base layer 110.

[0047] In some embodiments of the present disclosure, as Figures 2 to 19 ​As shown, the material for preparing the base layer 110 can be selected from any one of glass, polyimide (PI), and polyethylene terephthalate (PET).

[0048] In the related art, the black background of the display module 10 can be achieved by the combined action of the black pressure-sensitive adhesive and the support structure layer 300 or the ultra-clean foam composite film 400, so that the display module 10 presents an integrated black effect. However, since the hue of the black pressure-sensitive adhesive cannot be changed, when achieving the integrated black effect of the display module 10, only the optical density and / or hue value of the ink area 13 can be adjusted to adjust the integrated black value of the display module 10. The debugging range is greatly limited, and it is difficult to control the integrated black value of the display module 10 below 1.5. In this application, as Figures 2 to 19 shown, a first black ink layer 200 is provided on the side of the base layer 110 away from the display side of the display panel 100. The thickness of the first black ink layer 200 can be flexibly adjusted, so that the purpose of debugging the optical density and / or hue value of the first black ink layer 200 can be achieved by adjusting the thickness of the first black ink layer 200. When achieving the integrated black effect of the display module 10, both the optical density and / or hue value of the first black ink layer 200 and the optical density and hue value of the ink area 13 can be adjusted to control the black state of the display module 10, and make the optical density and hue value of the first black ink layer 200 and the ink area 13 as close as possible or even the same. Thus, the debugging range of the integrated black of the display module 10 can be expanded to a certain extent, and the integrated black value of the display module 10 can reach below 1.5, and even the integrated black value of the display module 10 can reach below 1.0, which can significantly improve the integrated black effect of the display module 10 and enhance the user experience.

[0049] In some embodiments of the present disclosure, as Figures 2 to 19 shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, an adhesive layer 500 and / or a pressure-sensitive adhesive layer 600, and a support structure layer 300 and / or an ultra-clean foam composite film 400 that are sequentially stacked. Among them, the cover plate 700 (Cover Glass, CG) can be a glass cover plate 700 or an acrylic cover plate 700. The optical adhesive layer 1000 (Optically Clear Adhesive, OCA) is used to bond the cover plate 700 and the display panel 100 together. The adhesive layer 500 and / or the pressure-sensitive adhesive layer 600 are used to bond the side of the display panel 100 provided with the first black ink layer 200 to the support structure layer 300 and / or the ultra-clean foam composite film 400 together.

[0050] In some embodiments of the present disclosure, optionally, Figures 2 to 19 As shown, the adhesive layer 500 can be made of optically transparent adhesive.

[0051] In some embodiments of the present disclosure, the support structure layer 300 and / or the ultra-clean foam composite film 400 are used to support the display panel 100. Optionally, the ultra-clean foam composite film 400 may also have a buffering and / or heat dissipation function.

[0052] In some embodiments of the present disclosure, Figures 2 to 4 As shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, an adhesive layer 500, and a support structure layer 300 and / or an ultra-clean foam composite film 400 which are stacked in sequence. In this type of embodiment, on the one hand, the thickness of the first black ink layer 200 can be adjusted to cooperate with the ink area 13 to achieve the effect of debugging the integrated black of the display module 10, and while achieving the black state adjustment of the display module 10, the integrated black value of the display module 10 can also be improved; on the other hand, by replacing the relatively high-cost black pressure-sensitive adhesive in the related art with the first black ink layer 200 and the adhesive layer 500, the manufacturing cost of the display module 10 can be reduced to a certain extent. In addition, the adhesive layer 500 can fill the gap in the display module 10, which can solve the mold printing problem caused by the gap in the vehicle-mounted display module 10 to a certain extent, and improve the yield of the display module 10. Optionally, the adhesive layer 500 can be made of an optically transparent adhesive. The adhesive layer 500 formed of the optically transparent adhesive has a wider range of thickness options and stronger fluidity. In a display module 10 with a step, especially in a relatively large-sized vehicle-mounted display module 10, it can improve the effect of solving the mold printing problem caused by the height difference / step difference in the veneer to a certain extent. In this type of implementation, the process sequence of the display module 10 can be: evaporate the pixel layer 120 on the display side of the base layer 110; evaporate or print the first black ink layer 200 on the non-display side of the base layer 110; and assemble the support structure layer 300 and / or the ultra-clean foam composite film 400 after large-scale cutting.

[0053] In some embodiments of the present disclosure, Figures 5 to 7 As shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, a pressure-sensitive adhesive layer 600, and a support structure layer 300 and / or an ultra-clean foam composite film 400 that are sequentially stacked. In this type of embodiment, the thickness of the first black ink layer 200 can be adjusted to cooperate with the ink area 13 to achieve the effect of adjusting the integral blackness of the display module 10, thereby improving the integral blackness value of the display module 10.

[0054] In some embodiments of the present disclosure, Figures 8 to 10As shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, an adhesive layer 500, a pressure-sensitive adhesive layer 600, and a support structure layer 300 and / or a super-clean foam composite film 400, which are stacked in sequence. In such embodiments, on the one hand, the effect of debugging the integrated black of the display module 10 can be achieved by adjusting the thickness of the first black ink layer 200 to cooperate with the ink area 13, thereby increasing the integrated black value of the display module 10. On the other hand, the side of the display panel 100 provided with the first black ink layer 200 is adhered to the support structure layer 300 and / or the super-clean foam composite film 400 through a combined layer formed by the adhesive layer 500 and the pressure-sensitive adhesive layer 600. That is, the adhesion effect can be improved, and the step difference in the display module 10 can be filled by the adhesive layer 500, which can more effectively improve the stamping problem of the display module 10 and further increase the yield of the display module 10.

[0055] As an alternative embodiment, as Figures 2 to 19 shown, the display module 10 further includes a cover plate 700. The cover plate 700 is located on the light-emitting side of the display panel 100, and an edge black ink layer 800 is provided on the side of the cover plate 700 close to the display panel 100 and in the edge area of the cover plate 700.

[0056] In some embodiments of the present disclosure, as Figures 2 to 19 shown, an edge black ink layer 800 is provided on the side of the cover plate 700 close to the display panel 100 and in the edge area of the cover plate 700. The ink area 13 can be formed in the display module 10 through the edge black ink layer 800. Structures such as traces at the edge of the display module 10 can be shielded through the edge black ink layer 800 / ink area 13, making the appearance of the display module 10 more beautiful. When debugging the integrated black effect of the display module 10, the optical density and / or hue value of the first black ink layer 200 and / or the edge ink layer can be debugged to achieve the purpose of debugging the integrated black effect of the display module 10, and the integrated black effect of the display module 10 can be improved, so that the integrated black value of the display module 10 is below 1.5, and even the integrated black value of the display module 10 can be below 1.0, thereby achieving the purpose of improving the user experience.

[0057] As an alternative embodiment, the first black ink layer 200 is an evaporation ink layer or an inkjet ink layer.

[0058] In some embodiments of the present disclosure, the first black ink layer 200 is an evaporated ink layer or an inkjet ink layer. That is, the first black ink layer 200 can be formed on the side of the base layer 110 away from the display side of the display panel 100 by evaporation, or can be formed on the side of the base layer 110 away from the display side of the display panel 100 by inkjet printing. Therefore, the thickness of the first black ink layer 200 can be adjusted by controlling the thickness of a single evaporation or a single inkjet printing, and the thickness of the first black ink layer 200 can also be adjusted by the overall thickness of evaporation or inkjet printing more than once, making the thickness adjustment of the first black ink layer 200 more flexible and diverse.

[0059] As an alternative embodiment, the thickness of the first black ink layer 200 is less than or equal to 20 μm.

[0060] In some embodiments of the present disclosure, optionally, by making the thickness of the first black ink layer 200 less than or equal to 20 μm, it is possible to avoid the excessive thickness of the first black ink layer 200 from affecting the bonding with the adhesive layer 500 and / or the pressure-sensitive adhesive layer 600. In some embodiments, the thickness of the first black ink layer 200 can be thickness values such as 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, 15 μm, 16 μm, 17 μm, 18 μm, 19 μm, 20 μm, etc.

[0061] In some embodiments of the present disclosure, optionally, the thickness of the first black ink layer 200 can be 5 μm to 15 μm. In some embodiments, the thickness of the first black ink layer 200 can be thickness values such as 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, 15 μm, etc.

[0062] As an alternative embodiment, the thickness of the adhesive layer 500 is 100 μm to 250 μm.

[0063] In some embodiments of the present disclosure, when the adhesive layer 500 is provided in the display module 10, the thickness of the adhesive layer 500 is 100 μm to 250 μm, which can make the thickness of the adhesive layer 500 appropriate and the optional range of the thickness larger, can achieve filling the step difference in the display module 10, and can make the surface of the first black ink layer 200 flat. In some embodiments, the thickness of the adhesive layer 500 can be thickness values such as 100 μm, 110 μm, 120 μm, 130 μm, 140 μm, 150 μm, 160 μm, 170 μm, 180 μm, 190 μm, 200 μm, 210 μm, 220 μm, 230 μm, 250 μm, 250 μm, etc. As an alternative embodiment, the thickness of the pressure-sensitive adhesive layer 600 is 40 μm to 60 μm.

[0064] In some embodiments of the present disclosure, when the pressure-sensitive adhesive is provided in the display module 10, by making the thickness of the pressure-sensitive adhesive layer 600 40 μm to 60 μm, the pressure-sensitive adhesive layer 600 can have relatively good adhesiveness and improve the adhesion effect. In some embodiments, the thickness of the pressure-sensitive adhesive layer 600 is 40 μm, 41 μm, 42 μm, 43 μm, 44 μm, 45 μm, 46 μm, 47 μm, 48 μm, 49 μm, 50 μm, 51 μm, 52 μm, 53 μm, 54 μm, 55 μm, 56 μm, 57 μm, 58 μm, 59 μm, 60 μm, etc.

[0065] As an alternative embodiment, as Figures 11 to 19 shown, the display module 10 further includes a second black ink layer 900, and the second black ink layer 900 is located between the support structure layer 300 and / or the ultra-clean foam composite film 400 and the adhesive layer 500 and / or the pressure-sensitive adhesive layer 600.

[0066] In some embodiments of the present disclosure, as Figures 11 to 19 shown, by providing the second black ink layer 900 between the support structure layer 300 and / or the ultra-clean foam composite film 400 and the adhesive layer 500 and / or the pressure-sensitive adhesive layer 600, the second black ink layer 900 can be combined with the first black ink layer 200 to achieve a larger range of black state regulation, and broaden the regulation range of the integrated black of the display module 10. At the same time, optionally, the preparation material of the adhesive layer 500 can be an optically transparent adhesive. The adhesive layer 500 formed by using the optically transparent adhesive has a larger optional range of thickness and stronger fluidity. In the display module 10 with a step difference, especially in the in-vehicle display module 10 with a relatively large size, it can improve the effect of solving the problem of die stamping caused by the height difference / step difference in the veneer to a certain extent.

[0067] In some embodiments of the present disclosure, as Figures 11 to 13As shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, an adhesive layer 500, a second black ink layer 900, and a support structure layer 300 and / or an ultra-clean foam composite film 400, which are sequentially stacked. In this type of embodiment, on the one hand, the thickness of the first black ink layer 200, the thickness of the second black ink layer 900, and the ink area 13 can be adjusted to achieve the effect of adjusting the integrated black of the display module 10, and while achieving the black state adjustment of the display module 10, the integrated black value of the display module 10 can also be improved; on the other hand, the first black ink layer 200 and the adhesive layer 500 replace the relatively high-cost black pressure-sensitive adhesive in the related art, which can reduce the manufacturing cost of the display module 10 to a certain extent. In addition, the adhesive layer 500 can also fill the gap in the display module 10, which can solve the mold printing problem caused by the gap of the vehicle-mounted display module 10 to a certain extent, and improve the yield of the display module 10. Optionally, the adhesive layer 500 may be prepared using an optically transparent adhesive. The adhesive layer 500 formed using the optically transparent adhesive has a wider range of optional thicknesses and stronger fluidity. In a display module 10 with a step, especially in a vehicle-mounted display module 10 with a relatively large size, it can improve the effect of solving the mold printing problem caused by the height difference / step difference in the veneer to a certain extent.

[0068] In some embodiments of the present disclosure, Figures 14 to 16 As shown, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, a pressure-sensitive adhesive layer 600, a second black ink layer 900, and a support structure layer 300 and / or an ultra-clean foam composite film 400 that are sequentially stacked. In this type of embodiment, the thickness of the first black ink layer 200 can be adjusted to cooperate with the ink area 13 to achieve the effect of adjusting the integral blackness of the display module 10, thereby improving the integral blackness value of the display module 10.

[0069] In some embodiments of the present disclosure, Figure 19 to 19As shown in the figure, the display module 10 may include a cover plate 700, an optical adhesive layer 1000, a display panel 100, a first black ink layer 200, an adhesive layer 500, a pressure-sensitive adhesive layer 600, a second black ink layer 900, and a support structure layer 300 and / or a super-clean foam composite film 400, which are sequentially stacked. In such embodiments, on the one hand, the effect of debugging the integrated black of the display module 10 can be achieved by adjusting the thickness of the first black ink layer 200 and the cooperation between the second black ink layer 900 and the ink area 13, thereby increasing the integrated black value of the display module 10. On the other hand, the side of the display panel 100 provided with the first black ink layer 200 is adhered to the support structure layer 300 and / or the super-clean foam composite film 400 through a combined layer formed by the adhesive layer 500 and the pressure-sensitive adhesive layer 600. That is, the adhesion effect can be improved, and the adhesive layer 500 can fill the step difference in the display module 10, which can more effectively improve the stamping problem of the display module 10 and further increase the yield rate of the display module 10.

[0070] In some embodiments of the present disclosure, the second black ink layer 900 is an evaporated ink layer or an inkjet ink layer.

[0071] In some embodiments of the present disclosure, the second black ink layer 900 is an evaporated ink layer or an inkjet ink layer, that is, the second black ink layer 900 can be formed on the support structure layer 300 or the super-clean foam composite film 400 by evaporation or inkjet printing, or the second black ink layer 900 can be formed on the support structure layer 300 by evaporation or inkjet printing. Therefore, the thickness of the second black ink layer 900 can be adjusted by controlling the thickness of a single evaporation or a single inkjet printing, and the thickness of the first black ink layer 200 can be adjusted by the overall thickness of evaporation or inkjet printing more than once, making the adjustment of the thickness of the first black ink layer 200 more flexible and diverse.

[0072] As an alternative embodiment, the thickness of the second black ink layer 900 is less than or equal to 20 μm.

[0073] In some embodiments of the present disclosure, optionally, by making the thickness of the second black ink layer 900 less than or equal to 20 μm, it is possible to avoid the excessive thickness of the second black ink layer from affecting the adhesion to the adhesive layer 500 and / or the pressure-sensitive adhesive layer 600. In some embodiments, the thickness of the first black ink layer 200 can be 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm, 8 μm, 9 μm, 10 μm, 11 μm, 12 μm, 13 μm, 14 μm, 15 μm, 16 μm, 17 μm, 18 μm, 19 μm, 20 μm, etc.
