The display assembly 000 may include: a display substrate 100 , a cover plate 200 and a middle frame 300 .

The display substrate 100 has a display area 100b and a non-display area 100a located at the periphery of the display area 100b. The display area 100b is an area where the display substrate 100 displays images, and the non-display area 100a is usually arranged with a plurality of signal lines for controlling the display area 100b to display. Here, the non-display area 100a does not display a picture, but visually appears as a black area. For this reason, the part of the display substrate 100 located in the non-display area 100a can be generally referred to as the black border of the display component.

In addition, the first frame 301 can completely cover the non-display area 100 a of the display substrate 100 , so that the non-display area 100 a of the display substrate 100 will not be partially covered by the first frame 301 , thereby effectively improving the performance of the display assembly 000 screen ratio.

In the present application, please refer to FIG. 5 , which is a schematic structural diagram of another display component provided by an embodiment of the present application. An adhesive layer 400 is disposed between the first frame 301 and the display substrate 100 , and the first frame 301 is bonded to the display substrate 100 through the adhesive layer 400 . In this way, the non-display area 100 a and the first frame 301 of the display substrate 100 are bonded to the non-display area 100 a of the display substrate 100 through the adhesive layer 400 , so that the display substrate 100 is assembled in the display assembly 000 .

In the embodiment of the present application, the orthographic projection of the cover plate 200 on the display substrate 100 does not coincide with the orthographic projection of the adhesive layer 400 on the display substrate 100 . In this way, when the display area is observed from one side of the cover plate 200 of the display assembly 000, the adhesive layer 400 cannot be seen visually, so that the assembled display assembly 000 cannot see the adhesive area.

In the embodiments of the present application, there are various structures of the adhesive layer 400 in the display assembly 000 , and the embodiments of the present application take the following two implementation manners as examples for schematic illustration.

In a first implementation manner, the adhesive layer 400 is an annular adhesive strip distributed in the non-display area 100 a of the display substrate 100 .

It should be noted that, in order to ensure the firmness of the ring-shaped rubber strip to bond the first frame 301 and the display substrate 100, it is necessary to ensure that the width of the ring-shaped rubber strip is relatively large, but one side of the ring-shaped rubber strip cannot exceed the display substrate 100. in the non-display area 100a. For example, the width of the annular rubber strip may be the maximum width of the non-display area 100 a in the display substrate 100 .

In this case, the operator can stick the ring-shaped adhesive strip on the part of the display substrate 100 located in the non-display area 100a, and then stick the first frame 301 on the part of the display substrate 100 facing the non-display area 100a side The connection between the first frame 301 and the display substrate 100 can be realized by being closed on the annular rubber strip.

In a second implementation manner, the adhesive layer 400 is a dispensing glue distributed in the non-display area 100 a of the display substrate 100 .

Exemplarily, in order to ensure the firmness of the glue dispensing to the first frame 301 and the display substrate 100, the glue needs to be distributed evenly in the non-display area 100a of the display substrate 100, and the distribution density of the glue needs to be ensured. larger.

In this case, the operator can form uniformly distributed glue on the part of the display substrate 100 located in the non-display area 100a through the glue dispenser, and then orient the first frame 301 toward the non-display area 100a in the display substrate 100 The connection between the first frame 301 and the display substrate 100 can be realized by attaching a part of one side to the dispensing glue.

In the embodiment of the present application, the adhesive layer 400 in the above two implementation manners may both be thermosetting adhesive or light curing adhesive. Among them, thermosetting glue refers to a glue that forms a bonding effect by heating and curing. For example, the thermosetting glue can be an improved epoxy adhesive; light curing glue means that the glue can be cured by light to form a sticky adhesive. A glue for bonding effect, for example, the light-curable glue can be UV glue that is cured under ultraviolet irradiation. In this embodiment of the present application, any glue may be used to achieve the purpose of bonding the first frame 301 and the display substrate 100 .

For example, when the adhesive layer 400 is a thermosetting adhesive, during the connection process of the first frame 301 and the display substrate 100 , firstly, on the part of the first frame 301 facing the non-display area 100 a of the display substrate 100 Apply a viscous thermosetting adhesive; then, turn the front surface of the display substrate 100 toward the first frame 301 on which the viscous thermosetting adhesive is formed, so that the part of the display substrate 100 located in the non-display area 100a is placed On the first frame 301 formed with viscous thermosetting adhesive; finally, heat treatment is performed on the stacked first frame 301 and the display substrate 100, so that the space between the first frame 301 and the display substrate 100 can be reduced. The viscous thermosetting adhesive is cured, and the cured thermosetting adhesive can realize the connection between the first frame 301 and the display substrate 100 .

When the adhesive layer 400 is a photocurable adhesive, during the connection process of the first frame 301 and the display substrate 100 , firstly, the first frame 301 may be coated on the portion of the display substrate 100 facing the non-display area 100 a side thick photo-curable adhesive; then, the front side of the display substrate 100 faces the first frame 301 formed with the viscous thermosetting adhesive, so that the part of the display substrate 100 located in the non-display area 100a is placed on the On the first frame 301 of the viscous photo-curable adhesive; finally, the photo-curable adhesive between the first frame 301 and the display substrate 100 is subjected to light treatment, so that the first frame 301 and the display substrate 100 The viscous photocurable adhesive is cured, and the cured photocurable adhesive can realize the connection between the first frame 301 and the display substrate 100 .

It should be noted that, before the first frame 301 and the display substrate 100 are bonded by the adhesive layer 400 , the surface of the first frame 301 and the surface of the display substrate 100 need to be pretreated. For example, deionized water or degreasing agent can be used to clean the surface of the non-display area 100a of the display substrate 100 and the surface of the first frame 301 facing the non-display area 100a of the display substrate 100 to ensure adhesion. When the layer 400 is adhered to the display substrate 100 , the firmness is high, and the firmness of the adhesive layer 400 and the first frame 301 when adhered is guaranteed to be high.

Here, the first polarizer 101 and the display substrate 100 are bonded by optical glue. For example, the portion 101 a of the first polarizer 101 located in the non-display area 100 a is bonded to the display substrate 100 . It should be noted that the width of the portion 101a of the first polarizer 101 located in the non-display area 100a is 0.5 mm.

In this case, the width of the adhesive layer 400 is less than or equal to 0.5 mm. Here, the maximum width of the adhesive layer 400 does not exceed the same width as the portion 101 a of the polarizer 101 in the display substrate 100 located in the non-display area 100 a. For example, the width of the adhesive layer 400 may be 0.5 mm and the thickness may be 0.15 mm. In this way, the display assembly 000 assembled through the adhesive layer 400 will not see the adhesive area.

In the present application, the side of the first frame 301 facing the cover plate 200 is in contact with the cover plate 200 . In this way, in the process of assembling the display substrate 100 and the cover plate 200, the edge of the cover plate 200 will not exceed the boundary line between the non-display area 100a and the display area 100b in the display substrate 100, so that the assembled display assembly can be 000 won't see the sticky area. It should be noted that the present application adopts the precision bonding technology of charge-coupled device (English: Charge-coupled Device, CCD for short), so that the gap between the assembled display substrate 100 and the cover plate 200 is in the range of Within ±0.15mm.

Here, the side surface of the second frame 302 and the display substrate 100 may be bonded by any of the above-mentioned embodiments. In this way, the second frame 302 can protect the side surface of the display assembly 000 . Here, in order to ensure high reliability of the display assembly 000 , the first frame 301 and the second frame 302 may have an integrated structure. For example, the first frame 301 and the second frame 302 may be formed by one injection molding process.

Exemplarily, when the middle frame 300 is assembled into the display assembly 000, the L-shaped middle frame is turned upside down, so that the first frame 301 is attached to the part of the display substrate 100 located in the non-display area 100a. Glue is also coated between the side surface of the second frame 302 and the display substrate 100 to ensure the firmness between the second frame 302 and the display substrate 100 .

In the present application, the display assembly 000 may further include: a back cover 500 located on the back of the display substrate 100 , and the back cover 500 is connected to the second frame 302 in the middle frame 300 .

The second polarizer 102 and the display substrate 100 are also bonded by optical glue. In the present application, the polarization direction of the first polarizer 101 is perpendicular to the polarization direction of the second polarizer 102. Under the cooperation of the first polarizer 101 and the second polarizer 102, the display substrate 100 can display different colors by setting screen.

It should be noted that, as shown in FIG. 6 , the display assembly 000 may further include: a buffer layer 600 located between the back surface of the display substrate 100 and the back cover 500 . The buffer layer 600 may be adhered to the display substrate 100 and the back cover 500 by thermosetting adhesive, photo-setting adhesive, or double-sided adhesive. In this way, the buffer layer 600 can also play a role of buffering and shock absorption for the display substrate 100 . For example, when the display assembly 000 is subjected to an external force, the buffer layer 600 can buffer part of the external force, so that the display substrate 100 is not easily broken. Here, the buffer layer 600 may be composed of foam.

After that, a voltage difference is formed between the pixel electrode 10043 and the common electrode under the action of the electrical signal. , so that the liquid crystal molecules in the display substrate 100 are deflected under the action of the electric field force. In this way, light can pass through the display substrate 100 so that the display substrate 100 can display a picture.

It should be noted that the above-mentioned display substrate 100 may be a flat display substrate 100 or a curved display substrate 100 . For example, when the display substrate 100 is a curved display substrate 100 , it is only necessary to adjust the shapes of the first frame 301 and the second frame 302 , and the first frame 301 can cover the non-display area 100 a of the display substrate 100 .
