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.
Fig. 1 is a schematic diagram of a cross-sectional structure of a display screen according to an exemplary embodiment, and as shown in fig. 1, the display screen includes:
a cover plate 101;
a shielding part 102, which is located on the cover plate 101 and encloses a space with an opening with the cover plate 101;
a protective layer 103, which is parallel and opposite to the cover plate 101, and covers at least part of the opening of the space;
and a display component 104, located in the space and between the cover plate 101 and the protective layer 103, configured to generate light for displaying a picture.
The display screen provided by the embodiment of the disclosure can be applied to display products such as smart phones, vehicle-mounted displays, medical monitors, industrial control equipment displays, home appliance displays and other consumer electronic displays. In practical applications, the display screen may be located on the surface of a product such as a smart phone, a vehicle-mounted display, a medical display, an industrial control device display, a home appliance display, and other consumer electronic displays. For example, the display screen may be adhered to the surface of a smart phone, a vehicle display, a medical display, an industrial control device display, a home appliance display, or other electronic display by means of adhesion.
In some embodiments, the display screen may include: cover plate 101, protective layer 103, and display assembly 104, etc. Wherein the display assembly 104 is located between the cover plate 101 and the protective layer 103.
Here, the display assembly 104 may include an LCD (Liquid Crystal Display) display assembly, and may also include an OLED (Organic Light-Emitting Diode) display assembly. Taking the display screen as an OLED display screen as an example, the display assembly 104 may include a light emitting layer, a polarizing layer, and the like in the display screen, where the light emitting layer may emit visible light signals of different colors, and the polarizing layer may receive the visible light signals generated by the light emitting layer and convert the visible light signals into polarized light, thereby forming a display screen on the display screen. For example, the display assembly 104 may include an organic light emitting layer and a polarizer or the like in a flexible OLED display screen.
In some embodiments, the display device 104 may generate light for displaying a picture, but since the thickness of the display device 104 is very thin (e.g. 30 μm), the display device 104 is easily deformed by being pressed by other devices when installed in a display screen, so that the display device 104 cannot generate light for displaying a picture, or the generated light cannot completely display a picture. In this case, the protective layer 103 is located under the display assembly 104, and may serve to support and protect the display assembly 104 from being pressed by the display assembly 104.
The cover plate 101 may be located on the surface of the display screen, and the surfaces of the display screen are often exposed to air during the use process of the smart phone, the vehicle-mounted display, the medical display, the industrial control equipment display, the home appliance display and other electronic displays, and certain abrasion is caused to the surfaces of the display screen due to artificial touch and use. In the embodiment of the disclosure, the cover plate 101 may cover the display assembly 104 entirely, so as to avoid the display assembly 104 from being exposed to air, and protect the functions of the display assembly 104 from being affected during the process of using the terminal device.
In some embodiments, the cover plate 101 may be made of transparent glass and super-porcelain glass, wherein the main component of the transparent glass is silicon dioxide and other oxides, and the super-porcelain glass is made of aluminosilicate glass as a raw material, and has the characteristics of hardness, scratch resistance and light transmission. The cover plate 101 may be located on a side of the display assembly 104 near the display surface of the terminal device, and may cover the display assembly 104 for protecting the display assembly 104.
In the embodiment of the disclosure, one side of the shielding part 102 contacts with one surface of the cover plate 101, and encloses a space with an opening together with the cover plate 101; the protective layer 103 is disposed in parallel with the cover plate 101 and contacts the other side of the shielding part 102 such that the protective layer 103 may cover at least part of the opening of the space. The display assembly 104 can be located in the space formed by the cover plate 101, the shielding part 102 and the protective layer 103, in this case, the cover plate 101, the shielding part 102 and the protective layer 103 can all play a role in protecting the display assembly 104, so that the possibility that external gas or liquid enters the display screen is reduced, the functions of the display assembly 104 are further protected from being influenced, and the probability of failure of the display screen is reduced.
In some embodiments, in the case that the structures of the shielding portions 102 are different, the shapes and orientations of the openings in the space surrounded by the shielding portions 102 and the cover plate 101 may also be different. For example, the opening of the space surrounded by the shielding portion 102 and the cover plate 101 may be oriented in the direction without the shielding portion 102 and the direction facing away from the cover plate 101 at the same time, and fig. 2 is a schematic perspective view of the space surrounded by the shielding portion and the cover plate, as shown in fig. 2, where the space formed by the shielding portion 102 and the cover plate 101 together has an opening, and the opening may be oriented in the direction without the shielding portion 102 and the direction facing away from the cover plate 101 at the same time.
In some embodiments, the structure of the shield 102 may be provided as desired. For example, when it is necessary to form a space having openings facing both in the direction in which the shielding portion 102 is absent and in the direction away from the cover plate 101, a plurality of shielding portions 102 may be provided independently of each other. For example, three shielding portions 102 may be provided independently of each other, the three shielding portions 102 may be associated with respective sides of the cover plate 101, and a connection between adjacent shielding portions 102 may be established, thereby forming the space. In other embodiments, one shielding portion 102 may be provided, and each portion of the one shielding portion 102 may correspond to each side surface of the cover plate 101, thereby forming the space.
The structure of the one shielding portion 102 may be different from that of each shielding portion 102 among the plurality of shielding portions 102. For example, each of the plurality of shielding portions 102 may be a planar structure, and the one shielding portion 102 may be a curved structure.
In other embodiments, the position of the shielding part 102 on the cover plate 101 has a predetermined distance from the edge of the cover plate 101, wherein the position of the shielding part 102 on the cover plate 101 may include: the shielding portion 102 is located at a position where the side contacting the cover plate 101 is located. It should be noted that, in the embodiment of the present disclosure, the edge where the shielding portion 102 contacts the cover plate 101 may be parallel to the edge of the cover plate 101, that is, the perpendicular distance between each point on the same edge and the edge of the cover plate 101 is equal. In other embodiments, the edge of the shielding portion 102 that contacts the cover plate 101 may not be parallel to the edge of the cover plate 101, i.e., the perpendicular distance between points on the same edge and the edge of the cover plate 101 may not be equal.
It will be appreciated that the distance between the location of the shield 102 on the cover plate 101 and the edge of the cover plate 101 may include: the shielding portion 102 is in contact with the cover plate 101 at a vertical distance from one of the edges of the cover plate 101.
In some embodiments, the preset distance may be set as desired, the preset distance being a value that may be greater than or equal to 0. Fig. 3 is a schematic perspective view two of a space enclosed by the shielding portion and the cover plate according to an exemplary embodiment, and as shown in fig. 3, the shielding portion 102 is spaced from the edge of the cover plate 101 by a distance d1, and is also formed on three sides of the cover plate 101, and forms a space with an opening facing in a direction without the shielding portion 102 and a direction facing away from the cover plate 101 together with the cover plate 101.
In the embodiment of the disclosure, the shielding part 102 is formed on the cover plate 101 in a surrounding manner, and the projection of the display assembly 104 on the cover plate 101 is located in the space. Fig. 4 is a perspective view III of a space surrounded by the shielding part and the cover plate according to an exemplary embodiment, as shown in fig. 4, the shielding part 102 is formed around the cover plate 101, and surrounds the cover plate 101 to form a space with an opening facing away from the cover plate 101, and the distance between the shielding part 102 and the edge of the cover plate 101 is d2.
In some embodiments, the shielding portion 102 is formed extending from the cover plate 101, and the extending direction of the shielding portion 102 faces the protective layer 103.
Here, the shielding portion 102 is formed to extend from the cover plate 101 and extend toward the protective layer 103, that is, the shielding portion 102 is integrated with the cover plate 101, and the portion extending out may contact the protective layer 103, and the shielding portion 102, the cover plate 101 and the protective layer 103 together form a space, so that the display assembly 104 is protected in the space. The shielding part 102 and the cover plate 101 are integrally arranged, so that the possibility that other gas or liquid in the air invades into the display screen from a contact gap between the shielding part 102 and the cover plate 101 can be reduced, the shielding part 102 extends to the protective layer 103, and the display assembly 104 can be better protected.
In some embodiments, the shield 102 extends from an edge of the cover plate 101.
Fig. 5 is a schematic perspective view of a space enclosed by the shielding portion and the cover plate according to an exemplary embodiment, and as shown in fig. 5, the shielding portion 102 is formed around the cover plate 101 and extends from the edge of the cover plate 101, it is understood that the shielding portion 102 is located on the cover plate 101 at a preset distance of 0 from the edge of the cover plate 101.
The shielding part 102 extends from the edge of the cover plate 101, namely, the shielding part 102 is integrally formed at the edge position of the cover plate 101, so that seamless connection can be realized, and the possibility that other gases or liquids in the air enter the display screen through a gap where the shielding part 102 is in contact with the cover plate 101 is further reduced.
In this way, the cover plate 101 is provided with the shielding portion 102 on one surface, the portion occupied by the shielding portion 102 is removed, and the portion surrounded by the shielding portion 102 and the cover plate 101 is a space having an opening, and the space can be used for installing internal components of the display screen.
In the embodiment of the disclosure, the shielding portion 102 is formed by extending from the edge of the cover plate 101, so that the space with an opening can be maximized, a larger space is reserved for the arrangement of the display assembly 104, and a narrower display screen frame can be realized.
In some embodiments, the shielding portion 102 is formed by etching the cover plate 101 through an etching process.
In the embodiment of the disclosure, the shielding portion 102 and the cover plate 101 are integrally formed, the cover plate 101 is made of glass, and when the shielding portion 102 is formed, a chemical reagent (such as hydrofluoric acid) can be used to etch a portion of the cover plate 101 through an etching process to form the shielding portion 102, so as to form a space with an opening.

In the case where the protective layer 103 is disposed parallel to the cover plate 101, the protective layer 103 just covers the opening facing the direction facing away from the cover plate 101 in the space formed by the shielding portion 102 and the cover plate 101, and the display assembly 104 is located in the sealed space formed by the cover plate 101, the shielding portion 102 and the protective layer 103.
The shielding part 102 formed around the cover plate 101 can protect the display assembly 104 more fully from the surrounding, and the formation of the sealing space can prevent other gases or liquids from entering the display screen from the gap between the cover plate 101 and the protective layer 103, thereby affecting the functions of the display assembly 104.

In some embodiments, the shell of the terminal device and the display screen may be bonded and sealed by using an edge sealing glue on the display screen, but although the width of the sealing glue can be reduced by various designs, so as to reduce the width of the frame of the display screen, in order to ensure that the display screen is firmly bonded, the sealing property is better, and a wider sealing glue is used for bonding, for example, the width of the sealing glue is about 0.8 millimeter (mm), and the width of the sealing glue still limits the reduction amplitude of the frame. In the embodiment of the disclosure, the width of the shielding part 102 is designed to be 0.2mm, which is smaller than the width of the sealant, so that not only can the display screen be protected, but also the width of the frame of the display screen can be reduced as much as possible.
In this disclosed embodiment, the display screen includes a cover plate 101, a shielding portion 102, a protection layer 103, and a display assembly 104, where the cover plate 101 and the shielding portion 102 may enclose a space with an opening, the protection layer 103 is parallel to the cover plate 101, and may cover at least a part of the opening of the space, and the display assembly 104 is located in the space between the cover plate 101 and the protection layer 103, and may generate light for displaying a picture.
By providing the shielding portion 102 on the cover plate 101 and making the shielding portion 102 and the cover plate 101 enclose a space with an opening, in this way, when the protective layer 103 covers at least a part of the opening of the space, the covered part can form a relatively sealed space, and the display assembly 104 located between the cover plate 101 and the protective layer 103 can be encapsulated in the relatively sealed space, so that not only the corrosion of the display assembly 104 caused by external gas and liquid can be effectively prevented. Under the condition that the display screen is installed on the terminal equipment, the possibility of damaging the display assembly 104 in a collision manner in the assembly process of the display screen and the shell of the terminal equipment can be prevented, light leakage is prevented, and moreover, as the shielding part 102 is arranged on the cover plate 101, the width of the frame of the display screen can be reduced.
