Detailed Description

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

The embodiment of the present disclosure provides a display device, as shown in fig. 1, and fig. 1 is a schematic structural diagram of a display device according to an exemplary embodiment. The display device 10 includes:

a display panel 11;

a transparent cover 12 disposed on the display panel 11 and covering the display panel 11;

a blind hole 13 disposed in the display panel 11 for placing an optical element;

and the dustproof coating 14 is coated at the bottom of the blind hole 13 and used for reducing the adhesion of dust to the bottom of the blind hole 13.

The display device shown in the embodiment of the disclosure can be applied to terminal devices such as smart phones and tablet computers, and taking the smart phones as examples, the display device can be screens of the smart phones.

The display device includes: a display panel and a transparent cover plate; and blind holes for placing optical elements are arranged in the display panel.

It should be noted that, in order to implement a real full-screen, at least one blind hole needs to be disposed in the display panel, and optical elements such as a camera and an optical fingerprint identification module need to be disposed in the blind hole below the display panel.

It is understood that the display panel has a display area and a below-screen transmissive area; the blind hole is located in the lower light-transmitting area of the screen. The display area is used for normal display, and the light-transmitting area under the screen is used for transmitting light so that the optical elements in the blind holes of the display panel can receive optical signals while displaying images.

In the embodiment of the present disclosure, the blind holes in the display panel may be formed by laser cutting; here, the number of the blind holes may be one or more; the position of the blind hole on the display panel can be set according to actual requirements; the embodiments of the present disclosure are not limited thereto. Illustratively, the blind hole may be a side single hole, a side double hole, a middle hole, or the like.

The transparent cover plate is arranged above the display panel and used for protecting the display panel and the optical elements arranged in the blind holes and preventing the external environment from directly damaging the display panel and the optical elements.

It can be understood that, the display panel is internally provided with the blind holes, and the periphery of the positions of the blind holes in the display device is provided with structures such as blind hole glue, a backlight source substrate and the like; as shown in fig. 2, fig. 2 is a schematic structural diagram of a blind hole in a display device provided in the related art. In the subsequent process of the display panel, the blind holes are exposed, so that dust in the external environment is easily accumulated in the blind holes, and the blind holes are polluted.

Because the blind hole position in the display device has a certain depth and the inner diameter is smaller (for example, 2-3 mm), the operation difficulty of the existing blind hole cleaning method, for example, the method of wiping the blind hole position by dipping alcohol with a cotton swab is higher; and the form of the blind hole glue can be easily damaged in the wiping process, so that the conditions of blind hole light leakage, blind hole unroundness and the like are caused, the display device becomes an unrepairable defective product, and the direct yield loss is caused.

Based on this, the embodiments of the present disclosure coat the bottom of the blind hole with the dust-proof coating, so that dust in the external environment falls on the dust-proof coating in the subsequent process of the display panel.

Here, the dust-proof coating can increase the surface smoothness of the bottom of the blind hole, reducing the adhesion of dust to the bottom of the blind hole.

In some embodiments, the dust-proof coating may have a micro-nano structure.

It can be understood that the micro-nano structure on the surface of the dustproof coating can reduce the contact area between dust and the surface of the dustproof coating, reduce the adhesion of the dust on the surface of the dustproof coating and reduce the dust accumulation in the blind hole.

In the embodiment of the present disclosure, when the dust-proof coating is coated on the surface of the blind hole, in order to avoid the influence of the dust-proof coating on the adhesion among the polarizer, the glue of the blind hole and the TFT substrate, the size of the dust-proof coating at the position of the blind hole may be set according to the minimum inner diameter size of the blind hole, so that the size of the dust-proof coating coated on the blind hole is the same as the minimum inner diameter size of the blind hole.

In the embodiment of the present disclosure, the thickness of the dustproof coating applied to the blind via may be set to 5 to 20nm.

It can be understood that, because the blind holes need to be used for placing optical elements, the thickness of the dustproof coating applied in the blind holes is not too thick or too thin; therefore, on one hand, the surface smoothness of the bottom of the blind hole can be guaranteed, and the adhesion of dust to the bottom of the blind hole is reduced; on the other hand, the blind hole space occupied by the dustproof coating is reduced, and on the other hand, the influence of the dustproof coating on incident light is reduced.

Optionally, the dust-proof coating comprises: a coating material which is formed by combining a reactive silane group and a fluorine modified organic group.

In the embodiment of the disclosure, the dustproof Coating can be an AF-Coating fingerprint-resistant Coating and is made of a Coating formed by combining a reactive silane group and a fluorine modified organic group.

The dust-proof coating is coated on the blind hole position, so that the blind hole position is in an oleophobic and hydrophobic state, dust and blind hole glue are not easy to adhere to the blind hole position, the probability of dust falling at the blind hole position is reduced, meanwhile, most of dust falling at the blind hole position can be blown off by an air gun in the cleaning process, and the residual dirt is easy to clean by a cotton swab; effectively reducing the wiping difficulty and the wiping reject ratio.

It should be noted that, the fluorine modified organic group can provide very low surface tension for the glass surface, so that the contact area of dust and the glass surface is reduced by 90%, the glass surface has strong hydrophobic, anti-oil and anti-fingerprint capabilities, and the adhesion of oil stain and dust drop is greatly reduced. In addition, the reactive silane groups can be closely checked with the texture of the glass surface so that they can be closely attached to the glass surface.

The side-in type backlight substrate is formed by arranging a backlight Light Emitting Diode (LED) Light bar at the edge of a back plate at the rear side of the TFT substrate, wherein Light emitted by the LED Light bar enters the Light guide plate from a Light incident surface at one side of the Light guide plate, is reflected and diffused, then is emitted from a Light Emitting surface of the Light guide plate, and then passes through an optical film group to form a surface Light source to be provided for the TFT substrate. In the direct type backlight substrate, a light source such as a Cathode Fluorescent Lamp (CCFL) and an LED light bar is disposed behind the TFT substrate, and a surface light source is directly formed to be provided to the TFT substrate. The embodiments of the present disclosure do not limit the type of the backlight substrate.

According to the embodiment of the disclosure, the optical element is mounted in the form of the blind hole arranged on the backlight source substrate, so that holes do not need to be formed on the TFT substrate, and on one hand, the processing is more convenient; on the other hand, when the optical element in the blind hole is opened, the optical element can receive an optical signal through the light-transmitting area of the TFT substrate, and other display areas on the TFT substrate normally display; when the optical element in the blind hole is closed, the light-transmitting area and other display areas on the TFT substrate can be normally displayed, full-screen display is realized, and the screen occupation ratio is improved.

In some embodiments, the display panel further comprises: and the shading black glue layer is arranged between the backlight source substrate and the first polaroid and surrounds the first through hole.

It can be understood that, in the embodiments of the present disclosure, the backlight substrate and the first polarizer are bonded by using the light-shielding black glue layer, so that cracking between the backlight substrate and the first polarizer, which causes light leakage from the cracked position, can be avoided.

Optionally, the display panel 11 includes:

a color filter CF substrate 114 attached to the TFT substrate 112;

and a second polarizer 115 disposed between the CF substrate 114 and the transparent cover 12, wherein a second through hole is disposed on the second polarizer 115, and the position of the second through hole on the second polarizer 115 corresponds to the position of the first through hole on the first polarizer 113.

In an embodiment of the present disclosure, the display panel includes: a CF substrate;
