Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
An embodiment of a display device is provided, and is described in detail below with reference to fig. 1 and 2.
The display device comprises a cover plate; the display panel assembly comprises a plurality of display panels 300 sequentially arranged on the cover plate 100 at intervals and a plurality of first transparent adhesive layers 200, wherein one side of a light-emitting surface of one display panel 300 is attached to the cover plate 100 through the corresponding first transparent adhesive layer 200, and similarly, the plurality of first transparent adhesive layers 200 are also sequentially arranged at intervals, namely the plurality of display panels are sequentially attached to the cover plate 100 through the first transparent adhesive layers 200 to realize splicing, so that a required large-size display surface is obtained;
specifically, the cover plate 100 is usually a glass cover plate with high light transmittance as the cover plate 100, and of course, when the display device needs to be applied to the field of flexible display, the cover plate 100 may also be a flexible transparent cover plate, which is not particularly limited in the embodiment of the present invention;
the specific type of the display panel 300 is not particularly limited, and may be a Mini LED display panel, a Micro LED display panel, an organic light emitting display panel, a liquid crystal display panel, and the like, where the display areas of the plurality of display panels 300 are generally the same size, and are attached to the cover plate 100 in an array distribution manner, for example, arranged in a 2 × n manner, for example, arranged in a 2 × 3 manner exemplarily illustrated in fig. 1;
further, in this embodiment, the first transparent adhesive layer 200 is made of a transparent adhesive material with a reduced viscosity under the irradiation of light with a predetermined wavelength, and when a display defect occurs on one or more display panels 300 in the display device, the light with the predetermined wavelength may be used to irradiate the corresponding first transparent adhesive layer 200, so that the viscosity of the corresponding first transparent adhesive layer 200 is reduced to below a threshold value, and thus the display panel 300 with the display defect may be peeled off from the cover plate 100, that is, when only a part of the display panels in the display device have the display defect, the display panel with the defect may be repaired and replaced only.
The following will specifically describe the steps and principles of the display device provided in this embodiment for repairing and replacing the display panel with reference to fig. 3a to 3 c:
specifically, referring to fig. 3a, when one or more display panels 300 in the display device have poor display, a mask 600 is covered on a side of the cover plate 100 away from the plurality of display panels 300, the mask 600 only covers the normally displayed display panels 300, so that the display panels 300 having poor display are exposed, under the shielding of the mask 600, the corresponding first transparent adhesive layers 200 are irradiated with light of a predetermined wavelength, and the viscosity of the corresponding first transparent adhesive layers 200 is reduced to below a threshold value;
the mask 600 may include a plurality of sub-masks having an area slightly larger than that of the display panel, and in actual operation, the sub-masks are covered one by one above the normally displayed display panel 300;
the illumination intensity and the illumination time depend on the material and the thickness of the first transparent adhesive layer 200, so that the viscosity of the first transparent adhesive layer 200 is reduced to be below a threshold value;
when the viscosity of the first transparent adhesive layer 200 is lower than the threshold value, the corresponding display panel 300 can be easily peeled off from the cover plate 100 without damaging the pasted interface;
referring to fig. 3b, after the illumination is finished, the mask 600 and the display panel 300 with poor display are removed;
referring to fig. 3c, a normally displayable display panel is provided, and the first transparent adhesive layer 200 is attached to the corresponding area of the cover plate 100 to complete the maintenance and replacement, so that the display device can be put into use again;
the maintenance and replacement operation process is simple, the operation cost is low, and the method is suitable for industrial application.
In some embodiments, the display panel 300 includes a display area, and an orthographic projection of any one of the first transparent adhesive layers 200 on the corresponding display panel 300 covers the display area of the display panel 300, so that the display surface of the display panel 300 and the cover plate 100 are completely filled with a transparent adhesive material, thereby avoiding a problem that a gap corresponding area has a higher reflectivity to ambient light due to a gap between the display surface of the display panel 300 and the cover plate 100, so that a display contrast of a display device in the area is reduced, and a display effect is affected, that is, the display contrast of the display panel can be effectively improved by completely filling the display surface of the display panel 300 and the cover plate 100 with the first transparent adhesive layer 200.
Further, in some embodiments, the display panel 300 further includes a frame region disposed on the peripheral side of the display region, the frame region is shaped like a Chinese character 'kou', the edge of the first transparent adhesive layer 200 is located in the frame region of the display panel 300, so as to avoid that the first transparent adhesive layer 200 is exposed outside the corresponding display panel 300 to cause other defects on the premise that the first transparent adhesive layer 200 completely covers the corresponding display region of the display panel 300.
In some embodiments, the material of the first transparent adhesive layer 200 includes a transparent adhesive material with a reduced viscosity under the irradiation of ultraviolet light, so that the first transparent adhesive layer 200 can have a reduced viscosity under the irradiation of ultraviolet light, and thus, in normal display, the display device is generally in a visible light environment, and the ultraviolet light is received very little, and does not affect the viscosity substrate of the first transparent adhesive layer 200.
Illustratively, the transparent glue material with reduced viscosity under ultraviolet light irradiation can be a compound represented by the following structural formula:
wherein n represents the degree of polymerization, and n is an integer of 6-18, the compound has an ultraviolet light-responsive ortho-nitrobenzyl ester bond, so that the compound can quickly respond to ultraviolet light irradiation, break the ortho-nitrobenzyl ester bond in polymer molecules, degrade the polymer, further reduce or even disappear the viscosity of the polymer, and has no caking property.
In some embodiments, the display device may further include other structural layers for further improvement, specifically referring to fig. 4, a transparent support layer 400 and a second transparent adhesive layer 500 are further disposed between any one of the first transparent adhesive layers 200 and the corresponding display panel 300, and the transparent support layer 400 is disposed between the first transparent adhesive layer 200 and the second transparent adhesive layer 500;
in the display device provided in this embodiment, the first transparent adhesive layer 200, the transparent supporting layer 400 and the second transparent adhesive layer 500 stacked in layers can be regarded as a composite adhesive layer, wherein the transparent supporting layer 400 is sandwiched, so that the composite adhesive layer has a certain hardness, and compared with the single-layer first transparent adhesive layer 200, the composite adhesive layer has a lower attaching difficulty, and thus, poor display caused by poor attachment such as attaching wrinkles or attaching bubbles due to the excessively soft adhesive layer is avoided.
Further, in the display device provided in this embodiment, the transparent supporting layer 400 is a flexible film layer with a certain hardness, and has a good optical transmittance, so as to avoid a loss of brightness of the display panel 300, in general, the transparent supporting layer 400 is made of polyethylene terephthalate, that is, the transparent supporting layer 400 is a PET film layer, and of course, other film layers with a better mechanical strength and a higher light transmittance may be selected;
in addition, the material of the second transparent adhesive layer 500 may be an optical transparent adhesive material commonly used in the art, or the material of the second transparent adhesive layer 500 may also be the same as that of the first transparent adhesive layer 200, and both are transparent adhesive materials with reduced viscosity under the irradiation of light with a predetermined wavelength;
because the display panel internally comprises the light-tight structure, when the display panel is maintained and replaced by the display device, the light is irradiated from one side of the cover plate, so that the first transparent adhesive layer 200 close to one side of the cover plate 100 is set to be an adhesive layer formed by a transparent adhesive material with reduced viscosity under the irradiation of light with a preset wavelength, and the second transparent adhesive layer 500 only needs to be transparent and have viscosity, and can be formed by a conventional optical transparent adhesive material, so that the display device has lower manufacturing cost;
on the other hand, in some cases, the material of the second transparent adhesive layer 500 is a transparent adhesive material whose viscosity is reduced under the irradiation of light with a predetermined wavelength, when the light with the predetermined wavelength is irradiated, the viscosity of both the second transparent adhesive layer 500 and the first transparent adhesive layer 200 is reduced to below a threshold value, and when the display panel 300 is peeled from the cover plate 100, the display panel 300 is peeled off in the same way as the corresponding second transparent adhesive layer 500, which is more convenient for the maintenance of the display panel 300 with poor display, and therefore, according to actual requirements, the material of the second transparent adhesive layer 500 is selected to be an optical transparent adhesive material or a transparent adhesive material whose viscosity is reduced under the irradiation of light with a predetermined wavelength.
In some embodiments, referring to fig. 4, when the transparent support layer 400 and the second transparent adhesive layer 500 are disposed in the display device, at the convenience of the manufacturing process, the composite adhesive layer formed by combining the first transparent adhesive layer 200 with the transparent support layer 400 and the second transparent adhesive layer 500 is generally formed by cutting a large film formed by stacking the three structural layers into a desired shape, so that the first transparent adhesive layer 200 and the transparent support layer 400 and the second transparent adhesive layer 500 have the same shape, that is, an orthogonal projection of the transparent support layer 400 on the cover plate 100 coincides with an orthogonal projection of the first transparent adhesive layer 200 on the cover plate 100, and an orthogonal projection of the second transparent adhesive layer 500 on the cover plate 100 coincides with an orthogonal projection of the first transparent adhesive layer 200 on the cover plate 100.
In some embodiments, the thickness of the first transparent adhesive layer 200 is 10 micrometers to 100 micrometers, the thickness of the first transparent adhesive layer 200 is not too thin, otherwise, the display panel is liable to fall off from the cover plate due to insufficient viscosity, the thickness of the first transparent adhesive layer 200 is also not too thick, otherwise, when maintenance and replacement are required, it takes too long time to illuminate the first transparent adhesive layer 200 to reduce the viscosity of the first transparent adhesive layer 200 to below a threshold value, which affects the effect of maintenance and replacement, and the specific thickness of the first transparent adhesive layer 200 is determined by combining specific process conditions;
in addition, the specific thicknesses of the second transparent adhesive layer 500 and the transparent support layer 400 are also determined by combining specific process conditions, and are usually between 10 microns and 100 microns.
It should be noted that, in the above-mentioned display device embodiment, only the above-mentioned structure is described, and it is understood that, in addition to the above-mentioned structure, the display panel according to the embodiment of the present invention may further include any other necessary structure as needed, and the specific structure is not limited herein.
