Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

With the development of communication technology, touch panels are mostly used in current electronic devices, and the touch function of the touch panel can be implemented by various sensors with different principles. In the use process, the hands given by the user frequently operate on the surface of the touch panel, so that static electricity is easily accumulated on the touch panel. The following problem is how to solve the static problem of the touch panel while satisfying the good display effect of the touch panel.

At present, a mobile phone touch screen cover plate in the industry is generally only plated with an anti-fingerprint film (AF coating) on the surface, and the anti-fingerprint film is used for solving the problem of hand perspiration. Because CG body and anti-fingerprint film are high-resistance material, so touch screen apron surface is the static that accumulates easily in friction process, and then causes the damage to the display screen-like common LCD class display screen friction discolours, the front shot hole of POLED flexible display screen shows the bright problem.

In order to overcome the problems in the related art, the present disclosure provides a cover plate, a display panel and an electronic device.

According to a first aspect of embodiments of the present disclosure, there is provided a cover plate comprising: a substrate; the first functional layer is arranged on one surface of the substrate; and the second functional layer is arranged on one surface of the first functional layer, which is far away from the second surface of the substrate, wherein the first functional layer comprises a conductive layer so as to dissipate static electricity accumulated by friction of the cover plate.

In the present disclosure, the first functional layer includes a conductive layer having conductive properties, so that static electricity on the surface of the cap plate can be dissipated, and the cap plate thus provided has an antistatic effect

Fig. 1 is a schematic cross-sectional structure of a cover plate according to an exemplary embodiment.

As shown in fig. 1, the cover plate 10 of the present disclosure includes a substrate 100, a first functional layer 200, and a second functional layer 300. The substrate 100 may include a first face 101 and a second face 102, the first face 101 and the second face 102 being two sides of the substrate 100 facing away from each other.

In the present disclosure, the substrate 100 may be made of glass or plastic. In the present disclosure, the substrate 100 may be transparent such that light may pass through. The substrate 100 may provide a manufacturing effect for the first functional layer 200 and the second functional layer 300, and may protect electronic components disposed at the sides from being damaged by external foreign matters.

In the present disclosure, the first functional layer 200 may be disposed on the second side 102 of the substrate. For example, the first functional layer 200 may be a plating film that is plated on the second side 102 of the substrate.

In the present disclosure, the reflectivity of the first functional layer 200 may be less than or equal to about 5.2%. For example, the conductive layer may be a layer having a reflectance of less than or equal to about 5.2%, wherein the conductive layer may include an indium tin oxide layer, and the indium tin oxide layer may include indium tin oxide.

Further, the reflectance of the conductive layer may be less than or equal to about 4.6%, whereby good readability of the display contents may be maintained. For example, the conductive layer may have a reflectivity of about 4.6%, wherein the conductive layer may include a tin antimony oxide layer, and the tin antimony oxide layer may include tin antimony oxide. Specifically, the reflectivity of the first functional layer 200 is lower, so that most of the light can pass through the first functional layer 200 when the light passes through the cover plate 10 from inside to outside, thereby improving the display effect.

In the present disclosure, the first functional layer is a layer having a reflectance of less than or equal to about 5.2%. The reflectivity is less than or equal to about 5.2%, and good readability of the display content can be maintained. Specifically, the reflectivity of the first functional layer is lower, so that when light passes through the cover plate from inside to outside, most of the light can pass through the first functional layer, and the display effect is further improved.

In the exemplary embodiment of the present disclosure, the first functional layer 200 is a layer having a transmittance of about 87% or more. The transmittance of the first functional layer 200 is more than about 87%, for example, the transmittance of the first functional layer 200 may be about 90%, or may be about 92%. In the present disclosure, such an arrangement is made that a large portion of the light passing through the substrate 100 can pass through the first functional layer 200 to satisfy the display function of the electronic device.

In the present disclosure, the first functional layer 200 may be disposed on the first side 101 of the substrate 100. In the present disclosure, the first functional layer may be an antistatic layer for eliminating static electricity generated at the cover plate 10 when the user operates the electronic device.

In the present disclosure, a first functional layer 200 may be first plated on the second surface 102 of the substrate 100, so as to ensure that the surface of the cover plate 10 has good antistatic capability, and then other functional layers, such as the second functional layer 300, are plated.

In an exemplary embodiment of the present disclosure, the conductive layer of the first functional layer 200 may include a transparent conductive layer.

For example, the first functional layer 200 may be made of a transparent conductive material. The transparent conductive material has both conductive and transparent properties, so that light can pass through the transparent conductive material to meet the display function of the electronic equipment, and static electricity can be eliminated due to the conductive property of the transparent conductive material.

In an exemplary embodiment of the present disclosure, the transparent conductive layer of the first functional layer 200 may include one or more of an antimony Tin Oxide (ATO, antimony Tin Oxide) layer, an Indium Tin Oxide (ITO) layer, an aluminum doped zinc Oxide (AZO) layer, and a fluorine doped Tin Oxide (FTO) layer. For example, the first functional layer 200 may include a tin antimony oxide layer. The reflectivity of the tin antimony oxide layer is about 4.6%, and the light transmittance of the tin antimony oxide layer may be 92%. That is, the tin antimony oxide layer has a higher transmittance and a lower reflectance. Such properties allow the tin antimony oxide layer to satisfy the light-transmitting function of the first functional layer 200 and avoid affecting the display effect. For example, when light passes through the cover plate from inside to outside, most of the light can pass through the tin antimony oxide layer, thereby improving the display effect.

However, the present disclosure is not limited thereto, and in other embodiments, the transparent conductive layer of the first functional layer 200 may also include the aforementioned exemplary layers as long as the reflectivity is less than or equal to 5.2%.

In the present disclosure, the second functional layer 300 may be disposed at one side of the first functional layer 200, for example, may be disposed at an outer side of the first functional layer 200. The outer side of the first functional layer 200 may be a side of the first functional layer 200 remote from the second side 102 of the substrate 100.

It is noted that in this disclosure, inner and outer are relative concepts. Taking an electronic device as an example, one side of the display screen, on which a user can see the display image, is the outside, and the opposite side is the inside. The side of the cover plate 10 opposite to the display screen is the inner side and the side opposite to the display screen is the outer side.

In the present disclosure, the second functional layer 300 may be an anti-fingerprint layer, which may include one or more of an oleophobic layer, a hydrophobic layer, an anti-fouling coating, and the like. In the present disclosure, the fingerprint-preventing layer may be a nano-chemical material. Specifically, a layer of nano chemical material can be plated on the outer side surface of the first functional layer 200 in a vapor deposition manner, so that the tension of the surface of the cover plate is reduced to the minimum, the contact area between dust and the surface of a product is reduced by about 90%, and therefore, the product has stronger hydrophobic, fingerprint resistant and oil stain resistant capabilities in appearance.

Fig. 2 is a schematic cross-sectional structure of a cover plate according to another exemplary embodiment.

As shown in fig. 2, in an exemplary embodiment of the present disclosure, the second functional layer 300 may include openings 301 exposing at least a portion of the first functional layer 200, and protrusions 302 located between the openings 301. In the present disclosure, the opening 301 may be provided in plural, the projection 302 may be provided in plural, and the number of the opening 301 and the projection 302 is not particularly limited.

As shown in fig. 2, an opening 301 may be provided through the second functional layer 300, through which opening 301 the first functional layer 200 is exposed to the outside. In this arrangement, when the user operates the electronic device, the finger or other touch product may frequently contact the first functional layer 200 while contacting the second functional layer 300, and at this time, the cover plate 10 may achieve a better static electricity dissipation capability through the static electricity eliminating effect of the first functional layer 200. Thus, the present disclosure can avoid the problems of color change of the LCD display screen or brightness of the front-view hole display of the POLED flexible display screen caused by the electrostatic discharge of the cover plate 10 to the display screen.

In the present disclosure, the shape and size of the opening 301 are not limited as long as it can satisfy the fingerprint-proof function including the first functional layer 200 and the second functional layer 300 and enhance the static electricity dissipation effect of the first functional layer 200.

As shown in fig. 2, in an exemplary embodiment of the present disclosure, the widest distance L of the opening 301 may be 5nm to 20nm. The widest distance L of the openings 301 is within such a range that the anti-fingerprint function of the second functional layer 300 can be simultaneously satisfied and the first functional layer 200 is exposed to satisfy the electrostatic dissipation requirement.

In the disclosure, the display effect of the electronic equipment is improved, and the static electricity dissipation capability can be improved, so that the use experience of a user is improved.

As shown in fig. 2, in an exemplary embodiment of the present disclosure, the maximum height H of the protrusion 302 may be greater than or equal to 5nm. In general, the maximum height H of the protrusion 302 can be considered as the thickness of the second functional layer 300. The maximum height of the protrusions 302 is within such a range that the anti-fingerprint function of the second functional layer 300 can be simultaneously satisfied and the first functional layer 200 is exposed to satisfy the electrostatic dissipation requirement.

As shown in fig. 2, in an exemplary embodiment of the present disclosure, the plurality of protrusions 302 are uniform in height. The arrangement is such that the entire second functional layer 300 has a uniform thickness, and thus the overall static electricity dissipation effect and fingerprint prevention effect of the cover plate 10 can be uniform.

Fig. 3 is a schematic top view of a second functional layer according to an exemplary embodiment. Fig. 4 is a schematic top view of a second functional layer according to another exemplary embodiment.

As shown in fig. 3 and 4, in an exemplary embodiment of the present disclosure, the protrusions 302 may be provided in plurality, with the plurality of protrusions 302 being disconnected from each other. The plurality of protrusions 302 are disconnected from each other, so that the protrusions 302 form an island-shaped structure, which can improve the anti-fingerprint function of the second functional layer 300 and improve the electrostatic dissipation effect of the first functional layer 200. In the present disclosure, the shape and size of the protrusion 302 are not limited as long as it can satisfy the fingerprint-proof function including the first functional layer 200 and the second functional layer 300 and enhance the static electricity dissipation effect of the first functional layer 200. The shape of the plurality of protrusions 302 may be uniform or different.

In the present disclosure, the shape and size of the opening 301 are not limited as long as it can satisfy the fingerprint-proof function including the first functional layer 200 and the second functional layer 300 and enhance the static electricity dissipation effect of the first functional layer 200.

In the present disclosure, the second functional layer 300 may be a plating film plated on the first functional layer 200, and the first functional layer 200 may be plated on the substrate 100 first, so as to ensure good antistatic ability of the surface of the cover plate 10, and then the second functional layer 300 is plated.

In the present disclosure, the island-shaped growth of the protrusions 302 of the second functional layer 300 may be realized by controlling the film forming form of the second functional layer 300 (for example, increasing the temperature during film coating), or the like, and the islands are discontinuous, so that the first functional layer 200 may be kept exposed to the environment at a local position, thereby ensuring the antistatic effect.

Based on the same conception, the embodiment of the disclosure also provides a display panel.

Fig. 5 is a schematic cross-sectional structure of a display panel according to another exemplary embodiment. As shown in fig. 5, the display panel 20 of the present disclosure includes the cover plate 10 and the display screen 400 according to any of the foregoing embodiments, the display screen 400 is disposed on the first surface 101 of the substrate 100, and the light emitted by the display screen 400 is emitted through the cover plate 10.

In the method, the anti-static film layer is added on the touch screen cover plate, so that good static dissipation capacity can be achieved on the surface of the cover plate, static discharge of a display screen monomer is avoided, and the problems that a Liquid Crystal Display (LCD) picture changes color or a flexible display (POLED) front-shooting hole is bright in display and the like are avoided.

According to the technical scheme, the tin antimony oxide (ATO) coating layer is added on the touch screen cover plate, so that the antistatic capacity of the cover plate is improved. Meanwhile, by controlling the film forming form of the fingerprint-proof film, the tin antimony oxide (ATO) film layer can be directly contacted with the outside, and the contact effectiveness is ensured. Meanwhile, the reflectivity of the tin antimony oxide (ATO) film layer is lower, and the reflectivity of the ATO film coated film is equivalent to that of the conventional cover plate glass, so that the readability of the display screen is not affected.

Tin antimony oxide (ATO) coating is a coating scheme for improving the static problem of a display panel (LCD panel), and has the advantages of good static dissipation capability, stable process and high transmittance.

The fingerprint-proof coating film can be used for controlling the film forming form, improving the temperature during coating, enabling the film to grow in an island shape, enabling the islands to be discontinuous, keeping a tin antimony oxide (ATO) coating layer exposed to the environment at a local position, and ensuring the antistatic effect. For example, in vacuum coating, the temperature can be controlled to 150-180 ℃, which is a key factor for controlling island growth. The fingerprint (AF) preventing material is weak in wettability between the deposited matter and the ATO film layer of the substrate, and AF is more prone to mutually bonding in the deposition process, but is not easy to bond with the ATO film layer of the substrate, so that atoms or molecules of the deposited matter are first aggregated into countless isolated small cores on the surface of the substrate, and then three-dimensional islands are formed. And meanwhile, the temperature during vacuum coating is raised to the upper limit of the coating, so that the growth of network stages among islands can be effectively restrained.

In the method, a tin antimony oxide (ATO) coating film is firstly coated on the surface of the touch screen cover plate, so that good antistatic capability of the cover plate surface is ensured, and then an anti-fingerprint coating film is coated.

In an exemplary embodiment of the present disclosure, the display screen 400 may be a flexible display screen. Flexible displays are generally more sensitive to static electricity and are more prone to display problems due to static electricity. The static problem of the flexible display screen can be solved by the arrangement of the display screen.

Based on the same conception, the disclosed embodiments also provide an electronic device comprising a display panel as in any of the previous embodiments.

In the present disclosure, the first functional layer is a layer having a reflectance of less than or equal to about 5.2%. The reflectivity is less than or equal to about 5.2%, and good readability of the display content can be maintained. Specifically, the reflectivity of the first functional layer is lower, so that most of light rays can pass through the first functional layer when the light rays pass through the cover plate from inside to outside, and the display effect of the electronic device is further improved.
