Description

Display module

The present disclosure relates to a display module, and more particularly to a display module with a narrow bezel.

With the development of the technology industry, monitors are widely used in televisions, computers, and mobile phones. In recent years, narrow-frame flat-panel monitors have become the development trend of high-quality monitors due to their simplicity, beauty, and large visible area under the same size.

Currently, the most common way to achieve narrow bezel design is to reduce the glue coating area and the bezel width in the display module. Generally speaking, in order to avoid glue overflow during bonding, a baffle may be added to the periphery of the liquid glue or solid glue may be used as a stopper. However, both the baffle and the solid glue have their own width, resulting in a limit to the narrowing of the bezel.

Therefore, how to come up with a display module that can solve the above problems is one of the problems that the industry is eager to invest R&D resources to solve.

In view of this, one purpose of this disclosure is to propose a display module that can solve the above problems.

One aspect of the present disclosure is related to a display module including a frame, a plate, a first colloid and a second colloid. The plate has a display area and a peripheral area. The peripheral area surrounds the display area. The first colloid is formed by curing a first hydrocolloid layer. The second colloid is formed by curing a second hydrocolloid layer. The adhesive force of the second colloid is less than the adhesive force of the first colloid. The first colloid and the second colloid are arranged in the peripheral area of the plate and connect the plate and the frame.

In some embodiments, the first colloid and the second colloid contact each other and form a closed loop around the display area of the board.

In some embodiments, the frame has a raised portion corresponding to the position of the second colloid.

In some embodiments, the first colloid partially overlaps the raised portion.

In some embodiments, the second colloid further includes solid particles uniformly distributed in the second colloid.

In some embodiments, the solid particles are compressible particles.

In some embodiments, the solid particles have a particle size greater than or equal to 0.1 mm after compression.

In some embodiments, the solid particles include an opaque material.

In some embodiments, the solid particles have an optical density between OD1 and OD4.

In some embodiments, at a temperature of 23°C, the second colloid has an adhesion between 0.3 MPa and 0.5 MPa within 1 to 3 minutes after coating.

In some embodiments, the first colloid has a support property less than the second colloid.

In some embodiments, the support of the second colloid is 0.1 MPa.

In some embodiments, the first colloid and the second colloid are alternately arranged along the closed loop.

In some embodiments, the first colloid is continuously disposed between the plate and the frame to form a closed loop.

In some embodiments, the second colloid is continuously disposed inside the closed loop to form another closed loop.

In some embodiments, the second colloid is continuously disposed outside the closed loop to form another closed loop.

In some embodiments, the second colloid is intermittently disposed inside the closed loop.

In some embodiments, the second colloid is intermittently disposed outside the closed loop.

Another aspect of the present disclosure is related to a display module including a frame, a plate and a colloid. The plate has a display area and a peripheral area. The peripheral area surrounds the display area. The colloid is formed by curing a hydrogel layer. The hydrogel layer includes solid particles uniformly distributed in the hydrogel layer. The colloid is disposed in the peripheral area of the plate and connects the plate and the frame.

In some embodiments, the colloid surrounds the display area of the panel to form a closed loop.

In some embodiments, the solid particles are compressible particles.

In some embodiments, the solid particles have a particle size greater than or equal to 0.1 mm after compression.

In some embodiments, the frame has a raised portion.

In some embodiments, the solid particles include an opaque material.

In some embodiments, the solid particles have an optical density between OD1 and OD4.

In summary, in the display module of some embodiments of the present disclosure, two substances having high adhesion and high support are used, respectively, to ensure that the desired adhesion strength and gap between the board and the frame are provided at the same time. Further, a first colloid having high adhesion is provided to adhere the board and the frame, and a second colloid having high support is used to achieve a sufficient colloid height to retain a gap between the board and the frame, and before the first colloid is completely cured, the second colloid having high initial adhesion can provide pre-fixation of the board. In addition, by providing solid particles in the second colloid, the gap between the board and the frame can be maintained before the first colloid is completely cured. Compared with common display modules, the stopper and solid glue can be omitted, thereby achieving the effect of narrowing the frame.

These and other aspects of the present disclosure are described below in conjunction with the drawings to describe preferred embodiments, and the embodiments of the present disclosure will become apparent, but changes and modifications therein may be made without departing from the spirit and scope of the novel concepts of the present disclosure.

The following disclosure will now be more fully described here through figures and references, and some exemplary embodiments are illustrated in the figures. The present disclosure can be implemented in different forms and should not be limited by the embodiments mentioned below. However, these embodiments are provided to help a more complete understanding of the content of the present disclosure and fully convey the scope of the present disclosure to those skilled in the art.

In the drawings, the thickness of layers, films, panels, regions, etc., is exaggerated for clarity. Throughout the specification, the same reference numerals will refer to similar elements throughout the text. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to another element, or intermediate elements may also exist. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intermediate elements.

Please refer to FIG. 1, which is a schematic diagram of a board 100A, a first colloid 300A, and a second colloid 400A according to some embodiments of the present disclosure. In some embodiments, the board 100A is a display panel. As shown in FIG. 1, the board 100A has a display area 110A and a peripheral area 120A. The peripheral area 120A surrounds the display area 110A. The first colloid 300A and the second colloid 400A are disposed on the peripheral area 120A.

Please refer to FIG. 2, which is a schematic diagram of a display module formed by a board 100A and a frame 200A according to some embodiments of the present disclosure. Specifically, the board 100A is provided with a side (i.e., the side shown in FIG. 1) of the first colloid 300A and the second colloid 400A facing the frame 200A, so that the first colloid 300A and the second colloid 400A contact and adhere to the frame 200A. The top view of the display module formed is shown in FIG. 2, and the cross-sectional schematic diagram thereof cut along the line segment A-A is shown in FIG. 3. In some embodiments, the frame 200A is a metal shell.

Line segments A-A, B-B, and C-C in FIG. 2 are reference cross sections. It should be understood that although the components labeled in FIG. 2 are the plate 100A and the frame 200A, in the subsequent drawings, the display modules formed by other embodiments of the present disclosure are also depicted using the above three reference cross sections.

Please refer to Figure 3, which is a cross-sectional schematic diagram of the display module drawn according to the line segment A-A. As shown in Figure 3, the first gel 300A and the second gel 400A connect the board 100A and the frame 200A.

The first gel 300A is formed by curing the first hydrogel layer, and the second gel 400A is formed by curing the second hydrogel layer. In some embodiments, the first hydrogel layer and the second hydrogel layer include different components. The second gel 400A provides adhesive force to pre-fix the board 100A on the frame 200A before the first gel 300A is completely cured, and in the display module, provides support force for the board 100A to maintain the gap G between the board 100A and the frame 200A (as shown in Figure 4).

Further, in some embodiments, in an environment with a temperature of 23°C, the initial adhesion of the second gel 400A within 1 to 3 minutes after coating is between 0.3 MPa and 0.5 MPa to prevent the board 100A from slipping relative to the frame 200A during the curing process of the first hydrogel layer. It should be understood that throughout the specification, adhesion represents the stress required to peel the gel from the adherend. In other words, in some embodiments, in an environment with a temperature of 23°C, after the second gel 400A is adhered between the board 100A and the frame 200A, a stress between 0.3 MPa and 0.5 MPa is required to peel the second gel 400A from the board 100A or the frame 200A. In some embodiments, the initial adhesion of the second colloid 400A is greater than the initial adhesion of the first colloid 300A.

In some embodiments, the different compositions of the first hydrogel layer and the second hydrogel layer make the support of the second colloid 400A greater than the support of the first colloid 300A, so that in the display area 110A, there is a gap G between the board 100A and the frame 200A. It should be understood that throughout the specification, support represents the compressive stress that the colloid can withstand within a preset compression range. For example, in some embodiments, the second colloid 400A has a support of 0.1 MPa, which means that when the second colloid 400A is subjected to a compressive stress of 0.1MPa, the compression rate in the force direction is less than or equal to 30%.

In some embodiments, the different compositions of the first hydrogel layer and the second hydrogel layer make the adhesion of the first gel 300A after full curing greater than the adhesion of the second gel 400A. In other words, after the first gel 300A and the second gel 400A are fully cured, the adhesion between the board 100A and the frame 200A is mainly provided by the first gel 300A. For example, in some embodiments, the cured first gel 300A has an adhesion of more than 1 MPa.

Please refer to Figure 1 again. In some embodiments, the first colloid 300A and the second colloid 400A contact each other and form a closed loop around the display area 110A. In some embodiments, multiple first colloids 300A and second colloids 400A are alternately arranged along the closed loop. In this way, the second colloid 400A can provide even support for the board 100A, while the first colloid 300A provides adhesion between the board 100A and the frame 200A. At the same time, the first colloid 300A helps the second colloid 400A to stick to its position.

In the process of other embodiments, the first hydrogel layer is first applied intermittently at predetermined positions of the peripheral area 120A. Then the second hydrogel layer is applied and cured to form the second gel 400A to form a closed loop as shown in FIG. 1, and then the first hydrogel layer is cured to form the first gel 300A.

In some embodiments, the first hydrogel layer and the second hydrogel layer include UV wet-curable hot melt adhesive or the like having different compositions. For example, reactive polyurethane (PUR). Thus, in the manufacturing process, the first hydrogel layer can be applied to the predetermined position of the peripheral area 120A before the first hydrogel layer is applied. Then, the second hydrogel layer is applied to form a closed loop as shown in FIG. 1, and cured by ultraviolet light to form the second gel 400A, and then the first hydrogel layer is allowed to cure naturally. Before the first hydrogel layer is completely cured, the second gel 400A provides support and fixation functions.

Please refer to Figures 4 and 5, which are partial cross-sectional views of the display module drawn according to line segment B-B and line segment C-C, respectively. As shown in Figures 4 and 5, the first colloid 300A and the second colloid 400A are arranged between the plate 100A and the frame 200A, and are arranged alternately with each other along a closed loop (as shown in Figure 1), but not in parallel inside and outside.

Please refer to FIG. 6, which is a partial enlarged view of the display module according to block 6 in FIG. 2. As shown in FIG. 6, the first colloid 300A and the second colloid 400A contact each other to form a closed loop to prevent substances such as dust from entering the display area 110A, providing airtight and dustproof effects. In some embodiments, there is a clear contact interface between the first colloid 300A and the second colloid 400A.

FIG. 7 is a schematic cross-sectional view of a display module formed by a plate 100A and a frame 200B according to some embodiments of the present disclosure along line segment A-A, and FIG. 8 is a partial enlarged view shown in block 8 in FIG. 7. As shown in FIG. 7 and FIG. 8, compared with the frame 200A, the frame 200B further includes a plurality of protrusions 210. These protrusions 210 correspond to the positions of the second gel 400B, respectively, to facilitate positioning during the coating process. In addition, due to the provision of the protrusions 210, the second gel 400B can have a smaller thickness than the second gel 400A, and can provide sufficient support before curing.

In the embodiments corresponding to FIGS. 7 and 8 , since the adhesive force of the second colloid 400B is smaller than the adhesive force of the first colloid 300A, peeling may occur between the second colloid 400B and the first colloid 300A or between the second colloid 400B and the convex portion 210 at the edge of the protrusion 210. Therefore, as shown in FIGS. 9 and 10 , in some embodiments, the first colloid 300B partially overlaps the convex portion 210 to prevent the second colloid 400C with smaller adhesive force from peeling. FIG. 9 is a schematic cross-sectional view of a display module formed by a plate 100A and a frame 200B along line segment A-A according to other embodiments of the present disclosure, and FIG. 10 is a partial enlarged view of the display module shown in block 10 in FIG. 9. In addition, in this embodiment, the first colloid 300B can increase the adhesive area by means of the protrusion 210, provide a stronger gripping force, and increase the stability of the colloid.

Please refer to FIG. 11, which is a schematic diagram of a board 100B, a first colloid 300C, and a second colloid 400D according to some embodiments of the present disclosure. As shown in FIG. 11, the board 100B has a display area 110B and a peripheral area 120B. The first colloid 300C and the second colloid 400D are arranged on the peripheral area 120B. The first colloid 300C is arranged continuously to form a closed loop. The second colloid 400D is arranged continuously on the inner side of the first colloid 300C and contacts the first colloid 300C to form another closed loop. As shown in FIG. 1 and FIG. 11, while maintaining the same colloid coating width W, the board 100B has a smaller display area 110B and a larger peripheral area 120B than the board 100A.

Please refer to FIG. 12, which is a schematic diagram of the plate 100B, the first colloid 300D, and the second colloid 400E according to some embodiments of the present disclosure. As shown in FIG. 12, the first colloid 300D is continuously arranged to form a closed loop. Relative to the second colloid 400D, the second colloid 400E is continuously arranged on the outer side of the first colloid 300D and contacts the first colloid 300D to form another closed loop.

Please refer to FIG. 13, which is a schematic diagram of the plate 100B, the first colloid 300E and the second colloid 400F according to some embodiments of the present disclosure. As shown in FIG. 13, the first colloid 300E is continuously arranged to form a closed loop. Compared with the second colloid 400D in FIG. 11, the second colloid 400F is intermittently arranged on the inner side of the first colloid 300E and contacts the first colloid 300E.

Please refer to FIG. 14, which is a schematic diagram of the plate 100B, the first colloid 300F and the second colloid 400G according to some embodiments of the present disclosure. As shown in FIG. 14, the first colloid 300F is continuously arranged to form a closed loop. Compared with the second colloid 400E in FIG. 12, the second colloid 400G in FIG. 14 is intermittently arranged on the outer side of the first colloid 300F and contacts the first colloid 300F.

Please refer to FIG. 15, which is a schematic diagram of a board 100A, a first colloid 300G, and solid particles 500 according to other embodiments of the present disclosure. As shown in FIG. 15, in some embodiments, the display module can be bonded by a hydrogel layer, and solid particles 500 are added to the hydrogel layer so that the solid particles 500 are evenly distributed in the hydrogel layer to provide support. For example, as shown in FIG. 15, the first colloid 300G is disposed on the peripheral area 120A of the board 100A, and the solid particles 500 are evenly distributed in the first colloid 300G. The first colloid 300G surrounds the display area 110A and forms a closed loop.

FIG. 16 is a schematic cross-sectional view of a display module formed by a plate body 100A and a frame body 200A according to other embodiments of the present disclosure along line segment A-A. FIG. 17 is a schematic cross-sectional view of a display module along line segment B-B. FIG. 18 is a partial enlarged view of a display module shown in block 18 in FIG. 16.

Similarly, the first colloid 300G is formed by curing the first hydrocolloid layer. After curing, the first colloid 300G provides adhesion between the board 100A and the frame 200A. For example, in some embodiments, the cured first colloid 300G has an adhesion of more than 1 MPa.

During the process of curing the first hydrogel layer to form the first gel 300G, the solid particles 500 provide support to ensure that there is a required gap G between the board 100A and the frame 200A in the display area 110A. In some embodiments, the solid particles 500 are compressible particles. For example, the solid particles 500 are rubber balls.

Due to the pressure applied by the plate 100A, the solid particles 500 are compressed, so after the first hydrogel layer is completely cured, the solid particles 500 are in a compressed state. For example, in some embodiments, after the first hydrogel layer is cured, the particle size D of the compressed solid particles 500 is greater than or equal to 0.1 mm, as shown in FIG. 17. Correspondingly, the gap G between the plate 100A and the frame 200A is greater than or equal to 0.1 mm.

In order to prevent the display module from overflowing through the colloid, in some embodiments, the solid particles 500 include opaque materials. For example, the solid particles 500 have a transmittance close to that of the first colloid 300G. For example, the optical density of the solid particles 500 is between OD1 and OD4. In some embodiments, the solid particles 500 appear black.

Please refer to Figure 19, which is a schematic cross-sectional view of a display module formed by a plate 100A and a frame 200B along line segment A-A according to some embodiments of the present disclosure. Figure 20 is a partial enlarged view of block 20 in Figure 19.

Similar to the implementation of Figures 7 and 8, in Figures 19 and 20, the frame 200B further includes a plurality of protrusions 210. Due to the provision of the protrusions 210, the first colloid 300H can have a smaller thickness at some locations, and can provide sufficient support before solidification. At the same time, the solid particles 500 can have a smaller compressed particle size D, and can maintain a gap G between the plate 100A and the frame 200A. In addition, the first colloid 300H can increase the adhesion area through the protrusions 210, provide a stronger gripping force, and increase the stability of the colloid.

Please refer to FIG. 21, which is a schematic diagram of a plate 100A, a first colloid 300A, a second colloid 400A, and solid particles 500 according to some embodiments of the present disclosure. Different from the embodiment of FIG. 1, the display module of FIG. 21 further includes solid particles 500 uniformly distributed in the second colloid 400A.

Please refer to Figures 22, 23 and 24. Figure 22 is a schematic cross-sectional view of a display module formed by a plate body 100A and a frame body 200A according to other embodiments of the present disclosure along line segment A-A. Figure 23 is a schematic cross-sectional view along line segment B-B. Figure 24 is a partial enlarged view of a display module shown in block 24 in Figure 22. Different from Figures 3, 4 and 6, in this embodiment, the display module further includes solid particles 500 uniformly distributed in the second colloid 400A, providing further support for the second colloid 400A and increasing the stability of the colloid.

Please refer to Figures 25 and 26. Figure 25 is a schematic cross-sectional view of a display module formed by a plate 100A and a frame 200B according to other embodiments of the present disclosure along line segment A-A. Figure 26 is a partial enlarged view of a display module shown in block 26 in Figure 25. Different from Figures 9 and 10, the display module further includes solid particles 500 uniformly distributed in the second colloid 400A to provide further support for the second colloid 400A.

From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the display module of some embodiments of the present disclosure, the use of two materials with high adhesion and high support can ensure that the desired adhesion strength and gap between the board and the frame are provided at the same time. Further, a first colloid with high adhesion is provided to adhere the board and the frame, and at the same time, a sufficient colloid height is achieved by a second colloid with high support to retain a gap between the board and the frame, and before the first colloid is completely cured, the second colloid with high initial adhesion can provide pre-fixation of the board. In addition, by providing solid particles in the second colloid, the gap between the board and the frame can be maintained before the first colloid is completely cured. Compared with the common display module, the stopper and solid glue can be omitted, thereby achieving the effect of narrowing the frame.

The foregoing description is merely illustrative and descriptive of exemplary embodiments of the present disclosure and is not intended to limit the precise form of the invention disclosed by the present disclosure. The above teachings may be modified or varied.

The embodiments selected and described are used to explain the content of the present disclosure and their practical applications to inspire other technicians in the field to use the present disclosure and various embodiments, and make various modifications to meet the expected specific uses.
