Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner" and "outer" etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, when an element is referred to as being "formed on" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.
As shown in fig. 1, the display panel according to an embodiment of the invention has a structure diagram, and the generation of static electricity may cause abnormal light emission phenomena such as green (e.g. occurring in the region Z1), afterimage (e.g. occurring in the region Z2), and flash screen, which are unfavorable for the normal operation of the display device. On the basis, after the inventor researches and analyzes related electrostatic discharge technologies, the inventor finds that although electrostatic discharge of the display device can be achieved by the electrostatic discharge technology of additionally arranging the conductive adhesive at the edge of each film layer of the display device, the technology needs to cut the edge of each film layer to meet the bonding condition of the conductive adhesive, and the cut edge of each film layer may conflict with the initial film layer structure design, so that other functions of the display device are affected. In addition, the conductive adhesive in the above-mentioned technology is attached to the edge of each film layer, and the conductive contact area corresponding to the electrostatic discharge channel is not increased, which may result in an excessively slow electrostatic discharge rate. In summary, even though the related electrostatic discharge technology can meet the electrostatic discharge requirement to a certain extent, it is still difficult to avoid the large-scale adjustment of each film structure when the conductive adhesive is attached.
Therefore, in order to meet the electrostatic discharge requirement and the structural design requirement of the display device, the inventor innovatively improves the electrostatic discharge structure of the display device, can increase the conductive contact area between the display substrate and the electrostatic discharge layer through the electrostatic discharge connecting part to meet the electrostatic discharge requirement, and can avoid the large-amplitude structural adjustment of each film layer of the display panel, thereby meeting the structural design requirement of the display panel.
The display panel provided by the embodiment of the application can comprise an electrostatic discharge layer, an electrostatic discharge connecting part, a composite functional film layer and a display substrate. The display substrate is located on one side, away from the electrostatic discharge layer, of the composite function film layer, a first accommodating space is formed in one side, close to the display substrate, of the electrostatic discharge layer, the first accommodating space is located at the end portion of the composite function film layer, at least part of the electrostatic discharge connecting portion is accommodated in the first accommodating space, and the orthographic projection of the electrostatic discharge connecting portion accommodated in the first accommodating space on the electrostatic discharge layer is located in the electrostatic discharge layer.
By the design, the display substrate can be conducted with the electrostatic discharge layer through the electrostatic discharge connecting part, and the electrostatic discharge connecting part increases the conductive contact area of the display substrate and the electrostatic discharge layer, so that electrostatic charges gathered at the display substrate can rapidly and timely flow into the electrostatic discharge layer through the electrostatic discharge connecting part, and the electrostatic discharge effect is achieved. In addition, because the first accommodating space is designed based on the structure of the electrostatic discharge layer, the self structure and the shape of the relevant film layer can be greatly adjusted to the greatest extent, and the actual structural requirement of the display panel is met.
It is understood that the design of the electrostatic discharge connection portion can be realized by various embodiments, and two examples are exemplarily illustrated below. Of course, in practical implementation, the method is not limited to the following two embodiments.
An embodiment of the present invention may be understood as an embodiment in which the electrostatic discharge connection portion is entirely accommodated in the first accommodation space. Referring to fig. 2, the electrostatic discharge connection portion 11 may be entirely accommodated in the first accommodation space 61 and electrically connected to the display substrate 30 through the conductive layer 12. Further, the electrostatic discharge connection portion 11 is located at an edge of the electrostatic discharge layer 10 and surrounds the composite functional film layer 20. In some examples, the material of the electrostatic discharge layer 10 and the electrostatic discharge connection 11 may be copper foil.
It can be understood that, in the present embodiment, by designing the composite functional film layer 20 to be recessed, a space for disposing the electrostatic discharge connection portion 11 can be reserved on the electrostatic discharge layer 10, so that when the electrostatic discharge connection portion 11 is disposed on the electrostatic discharge layer 10, the conductive contact area between the electrostatic discharge layer 10 and the display substrate 30 can be increased. In addition, since the conductive layer 12 is additionally arranged between the electrostatic discharge connection portion 11 and the display substrate 30, and the conductive layer 12 may be a conductive adhesive with elasticity, it can be ensured that the display panel 100 in a slightly bent state can achieve effective electrical contact between the electrostatic discharge connection portion 11 and the display substrate 30 through the conductive layer, so as to ensure the conductive performance between the electrostatic discharge connection portion 11 and the display substrate 30, and further ensure that the electrostatic charges accumulated in the display substrate 30 can flow into the electrostatic discharge layer 10 through the conductive layer 12 and the electrostatic discharge connection portion 11, and are discharged through the ground conductor in conduction with the electrostatic discharge layer 10.
Referring to fig. 2 and fig. 3, the composite functional film 20 may include a first functional film 21 and a second functional film 22, the first functional film 21 and the electrostatic discharge connection 11 are located on the same side of the electrostatic discharge layer 10, an orthogonal projection of the first functional film 21 on the electrostatic discharge layer 10 is located in the electrostatic discharge layer 10, and accordingly, the second functional film 22 is located on a side of the first functional film 21 away from the electrostatic discharge layer 10, and an orthogonal projection of the second functional film 22 on the electrostatic discharge layer 10 coincides with an orthogonal projection of the first functional film 21 on the electrostatic discharge layer 10. Further, the display substrate 30, the first functional film layer 21, the second functional film layer 22 and the electrostatic discharge layer 10 together form a first accommodating space 61, and the conductive layer 12 may be accommodated in the first accommodating space 61 and conducted between the electrostatic discharge layer 10 and the display substrate 30.
Through the above design, the retraction design of the first functional film 21 and the second functional film 22 on the electrostatic discharge layer 10 can be realized, and the electrostatic discharge connection portion 11 is arranged around the first functional film 21 and the second functional film 22. In practical applications, the thicknesses of the electrostatic discharge connection portion 11, the first functional film layer 21, and the second functional film layer 22 may be designed to ensure relative stability among the electrostatic discharge layer 10, the electrostatic discharge connection portion 11, the first functional film layer 21, and the second functional film layer 22. As shown in fig. 3, the sum h1 of the thicknesses of the first functional film 21 and the second functional film 22 may be designed to be greater than the thickness h2 of the electrostatic discharge connection 11, so as to ensure that the first functional film 21 and the second functional film 22 are embedded in the groove formed by the electrostatic discharge layer 10 and the electrostatic discharge connection 11, thereby preventing relative sliding among the electrostatic discharge layer 10, the electrostatic discharge connection 11, the first functional film 21, and the second functional film 22, and ensuring relative stability among the electrostatic discharge layer 10, the electrostatic discharge connection 11, the first functional film 21, and the second functional film 22.
In some examples, the first functional film 21 may include a support thermal insulation layer, and a material of the support thermal insulation layer may be Polyimide (PI), so that the first functional film 21 may include a PI layer for supporting and insulating. The second functional film layer 22 includes a buffer layer, which may be composed of foam and grid glue.
Referring to fig. 2, the display substrate 30 may include a support film 31, a screen 32, and a polarizer 33. The support film 31 is located on a side of the second functional film 22 away from the first functional film 21 and is in contact with the conductive layer 12, the screen 32 is located on a side of the support film 31 away from the second functional film 22, and the polarizer 33 is located on a side of the screen 32 away from the support film 31. On the above basis, the display panel 100 may further include an adhesive layer 40 and a cover plate 50, where the adhesive layer 40 is located on a side of the polarizer 33 away from the panel 32, and the cover plate 50 is located on a side of the adhesive layer 40 away from the polarizer 33.
With reference to fig. 2 and fig. 3, in the using process of the display panel 100, if the electrostatic discharge layer 10 and the support film 31 are not conducted, the electrostatic charges generated on the surface of the cover plate 50 can flow into the screen 32 and the support film 31, the electrostatic charges induce positive charges on the side of the second functional film layer 22 close to the display substrate 30, and the electrostatic charges simultaneously induce electrons in a Low Temperature Poly-Silicon (LTPS) layer in the screen 32, which may cause static electricity to accumulate and discharge around the screen 32, thereby causing a problem of abnormal display.
Accordingly, by providing the electrostatic discharge connection portion 11 and the conductive layer 12 to conduct the electrostatic discharge layer 10 and the support film 31, the electrostatic charges accumulated around the shield 32 flow toward the conductive layer 12 having a low resistance and flow into the electrostatic discharge layer 10, and are then discharged through the ground conductor in conduction with the electrostatic discharge layer 10. Since the electrostatic discharge connection portion 11 can increase the conductive contact area between the electrostatic discharge layer 10 and the support film 31, the resistance between the electrostatic discharge layer 10 and the support film 31 can be effectively reduced, thereby increasing the rate of electrostatic discharge.
In practical implementation, the inventor found that, when designing the first functional film 21 and the second functional film 22 to be recessed, it is necessary to ensure that the operation performance of the display panel 100 is not affected as much as possible, and for this reason, the recessed extent of the first functional film 21 and the second functional film 22 can be adjusted. In some possible embodiments, referring to fig. 2 and fig. 4, an orthographic projection of the electrostatic discharge connection portion 11 on the electrostatic discharge layer 10 may be a closed ring shape, and a ring width d of the closed ring shape may be 0 to 6 mm. In practical implementation, the ring width d of the closed ring shape may be not greater than 5mm, in other words, the maximum retraction amplitude of the first functional film layer 21 and the second functional film layer 22 may be 5 mm.
For example, the distance between the orthographic projection of the first functional film layer 21/the second functional film layer 22 on the electrostatic discharge layer 10 and the edge of the electrostatic discharge layer 10 is less than or equal to 5mm, such as 5mm, 4.9mm, 4.8mm, 4.7mm, 4.6mm, 4.5mm, 4.4mm, 4.3mm, 4.2mm, 4.1mm, 4mm, 3.9mm, 3.8mm, 3.7mm, 3.6mm, 3.5mm, 3.4mm, 3.3mm, 3.2mm, 3.1mm, 3mm, 2.9mm, 2.8mm, 2.7mm, 2.6mm, 2.5mm, 2.4mm, 2.3mm, 2.2mm, 2.1mm, 2mm, 1.9mm, 1.8mm, 1.7mm, 1.6mm, 1.5mm, 1.4mm, 1.3mm, 1.2mm, 1.1mm, 1mm, 1.8mm, 1.7mm, 1.6mm, 1.5mm, 1.1mm, or the like, and the like, without being limited.
By designing the retraction width of the first functional film 21 and the second functional film 22, the working performance of the display panel 100 can be ensured to be as unaffected as possible on the premise of realizing the electrostatic discharge effect of the display panel 100, and the process feasibility of the retraction design of the first functional film 21 and the second functional film 22 is ensured.
Another embodiment of the present invention may be understood as an embodiment in which a portion of the electrostatic discharge connection portion is accommodated in the first accommodation space. Referring to fig. 5, the electrostatic discharge layer 10, the first functional film 21 and the second functional film 22 may form a first accommodating space 61, in this embodiment, the electrostatic discharge connection portion 11 may be formed of a conductive liquid or a liquid conductive adhesive, and based on this, the electrostatic discharge connection portion 11 may extend to the electrostatic discharge layer 10 from the side of the cover plate 50 close to the display substrate 30 along the edge of the display substrate 30, the edge of the second functional film layer 22, the edge of the first functional film layer 21, and the edge of the electrostatic discharge layer 10 in sequence, so as to conduct the cover plate 50 and the electrostatic discharge layer 10, wherein, part of the electrostatic discharge connection part 11 is accommodated in the first accommodation space 61, so that the conductive contact area between the electrostatic discharge connection part 11 and the electrostatic discharge layer 10 can be increased, therefore, the electrostatic charges generated on the surface of the cover plate 50 can rapidly flow to the electrostatic discharge layer 10 along the electrostatic discharge connection part 11 and the display substrate 30 to achieve the purpose of electrostatic discharge.
Based on this embodiment, please refer to fig. 5, fig. 6 and fig. 7 in combination, an orthographic projection of the first functional film layer 21 on the electrostatic discharge layer 10 is located in the electrostatic discharge layer 10, and an orthographic projection of the second functional film layer 22 on the electrostatic discharge layer 10 is overlapped with the electrostatic discharge layer 10, by performing an inward-contracting design on the first functional film layer 21, the electrostatic discharge layer 10, the first functional film layer 21 and the second functional film layer 22 can jointly form the first accommodating space 61, so that a part of the electrostatic discharge connection portion 11 is ensured to be filled in the first accommodating space 61 to increase a conductive contact area with the electrostatic discharge layer 10, thereby reducing a contact resistance between the cover plate 50 and the electrostatic discharge layer 10, improving a flow rate of electrostatic charges, and performing electrostatic discharge in real time.
In some possible embodiments, the distance between the orthographic projections of the first functional film layer 21 and the end of the electrostatic discharge layer 10 on the same side of the display panel 100 on the same plane (for example, on the display substrate 30) may be 0 to 6mm, for example, may be less than or equal to 5 mm. It is understood that the retraction depth of the first functional film layer 21 between the electrostatic discharge layer 10 and the second functional film layer 22 may be 5mm, 4.9mm, 4.8mm, 4.7mm, 4.6mm, 4.5mm, 4.4mm, 4.3mm, 4.2mm, 4.1mm, 4mm, 3.9mm, 3.8mm, 3.7mm, 3.6mm, 3.5mm, 3.4mm, 3.3mm, 3.2mm, 3.1mm, 3mm, 2.9mm, 2.8mm, 2.7mm, 2.6mm, 2.5mm, 2.4mm, 2.3mm, 2.2mm, 2.1mm, 2mm, 1.9mm, 1.8mm, 1.7mm, 1.6mm, 1.5mm, 1.4mm, 1.3mm, 1.2mm, 1.1.1 mm, or the like, and is not limited thereto. This ensures that the operation performance of the display panel 100 is not affected as much as possible while achieving the electrostatic discharge effect of the display panel 100, and ensures the process feasibility of the indented design of the first functional film layer 21.
In practical implementation, the inventor finds that, when the electrostatic discharge connection portion 11 is a conductive liquid, since the conductive liquid is an alkaline solution and has a certain corrosiveness, if the conductive liquid is directly coated on the surface of the electrostatic discharge layer 10, the surface of the electrostatic discharge layer 10 may be corroded, so that the overall appearance of the product is affected, and therefore, by filling a part of the electrostatic discharge connection portion 11 in the first accommodation space 61, the electrostatic discharge connection portion 11 and the electrostatic discharge layer 10 can be ensured to be in sufficient contact to increase the electrostatic discharge rate, and the corrosion area of the electrostatic discharge layer 10 can be reduced to a certain extent, so that the overall appearance of the product is ensured.
In other possible embodiments, referring to fig. 5, fig. 8 and fig. 9, an orthographic projection of the first functional film 21 on the electrostatic discharge layer 10 is located in the electrostatic discharge layer 10, and an orthographic projection of the second functional film 22 on the electrostatic discharge layer 10 is overlapped with an orthographic projection of the first functional film 21 on the electrostatic discharge layer 10, which may be understood as a situation where the first functional film 21 and the second functional film 22 are both indented, and then a portion of the electrostatic discharge connection 11 is filled in the first accommodating space 61 formed by the electrostatic discharge layer 10, the first functional film 21, the second functional film 22 and the display substrate 30. Further, the distance between the orthographic projections of the ends of the first functional film layer 21 (or the second functional film layer 22) and the electrostatic discharge layer 10 on the same side of the display panel 100 on the same plane may be 0-6 mm.
Based on the above embodiments, referring to fig. 5 and fig. 7, the display substrate 30 and the cover plate 50 may further form a second accommodating space 62 together, and at least a portion of the electrostatic discharge connection 11 may be filled in the second accommodating space 62, so that the conductive cross-sectional area of the electrostatic discharge connection 11 can be appropriately increased, thereby appropriately reducing the resistance of the electrostatic discharge connection 11 and increasing the electrostatic discharge rate. In some possible embodiments, the orthographic projection of the adhesive layer 40 on the display substrate 30 is located in the display substrate 30, and the display substrate 30, the adhesive layer 40 and the cover plate 50 together form the second accommodating space 62.
On the basis of the above, a display device is also provided, which includes the above display panel 100, and the display device has a better electrostatic discharge effect when in use, and can avoid the abnormal problems of afterimage, flash screen and the like when in use.
To sum up, in the display panel and the display apparatus provided in the embodiment of the invention, the first accommodating space 61 formed at one side of the electrostatic discharge layer 10 close to the display substrate 30 can accommodate at least part of the electrostatic discharge connection portion 11, and the display substrate 30 is conducted with the electrostatic discharge layer through the electrostatic discharge connection portion 11, so that the conductive contact area between the display substrate 30 and the electrostatic discharge layer 10 can be increased, and the electrostatic charges collected at the display substrate 30 can rapidly and timely flow into the electrostatic discharge layer 10 through the electrostatic discharge connection portion 11, thereby satisfying the electrostatic discharge requirement of the display panel 30.
