To solve the above problem, an embodiment of the first aspect of the present application provides a cover plate assembly 100.
Referring to fig. 1, the cover plate assembly 100 includes a cover plate 110, a light shielding layer 120 and an adhesive layer 130, the cover plate 110 includes a first surface 111, a second surface 112 and a recess 113, the first surface 111 and the second surface 112 are disposed opposite to each other, and the recess 113 is recessed from the first surface 111 toward a direction close to the second surface 112; the light shielding layer 120 is arranged in the concave portion 113 and covers the surface of the concave portion 113, a light shielding area A is formed at the part of the cover plate 110 covered by the light shielding layer 120, a light transmitting area B is formed at the part of the cover plate 110 not covered by the light shielding layer 120, and the light shielding area A is at least partially arranged around the light transmitting area B; the adhesive layer 130 is disposed on a side of the first surface 111 away from the second surface 112, the adhesive layer 130 located in the light-transmitting region B is attached to the first surface 111, the adhesive layer 130 located in the light-shielding region a is filled into the recess 113, and at least a portion of the adhesive layer 130 is attached to the light-shielding layer 120.
It can be understood that the cover plate 110 is made of glass or the like with high light transmittance, and the cover plate 110 is applied to the display panel to protect the display screen from being damaged by external force. The cover plate 110 may be made of a rigid material or a flexible material, so that the cover plate 110 may be folded, and may be applied to a flexible and foldable display panel. Illustratively, the cover plate 110 may be made of UTG (Ultra Thin Glass), CPI (transparent Polyimide), PET (Polyethylene Terephthalate), and other transparent, soft and foldable materials to realize the bendable folding of the cover plate 110.
The light-shielding layer 120 is applied to the display panel, on one hand, the light-shielding layer 120 is used for shielding a region without a display function in the display screen, so that the display panel is simpler as a whole; on the other hand, the light shielding layer 120 is used for shielding a part of light emitted by the display screen, and reduces or avoids light leakage generated when the cover plate 110 is applied to the display module, so that the display panel has a better display effect. The light-shielding layer 120 may be black ink so as to effectively block light from passing through, and the light-shielding layer 120 may cover the surface of the concave portion 113 by spraying or printing. The part of the cover plate 110 covered by the light shielding layer 120 forms a light shielding region A, the problems of diffraction, light leakage or visible wires and the like are avoided through the light shielding effect of the light shielding region A, and the part of the cover plate 110 not covered by the light shielding layer 120 forms a light transmitting region B, so that the light can be ensured to normally pass through. In some embodiments, when the cover plate 110 is attached to the display screen, the light-shielding region a corresponds to a non-display region of the display screen, and the light-transmitting region B corresponds to a display region of the display screen. In other embodiments, the transparent area B may further correspond to the photosensitive module, so that the external light enters the photosensitive module through the transparent area B, and the photosensitive module may be a camera module, an infrared sensor, or the like.
Optionally, the Adhesive layer 130 is an OCA (Optical Clear Adhesive) Adhesive layer, and of course, the Adhesive layer 130 may also be an Adhesive layer made of other materials, such as an OCR (Optical Clear Resin), an acrylic Adhesive material, or a silicone Adhesive, so that the Adhesive layer 130 can adhere to the cover plate 110 and the display screen.
Since the cover plate 110 provided by the present application has the concave portion 113, when the adhesive layer 130 and the cover plate 110 are attached, a part of the adhesive layer 130 may be filled into the concave portion 113 and attached to the light shielding layer 120, thereby reducing the possibility of air bubbles being generated between the cover plate 110 and the adhesive layer 130. Even if the adhesive layer 130 cannot completely fill the concave portion 113, only a part of the adhesive layer 130 filled into the concave portion 113 is attached to the light shielding layer 120, since a part of the adhesive layer 130 protrudes toward the concave portion 113 to be accommodated in the concave portion 113, bubbles generated between the adhesive layer 130 and the light shielding layer 120 can only exist in the concave portion, and since the concave portion 113 is covered by the light shielding layer 120, the bubbles can be covered by the light shielding layer 120, and light reflected or refracted by the bubbles cannot penetrate or bypass the light shielding layer 120 to a certain extent and is observed by a user, thereby improving the display effect of the display panel provided with the cover plate assembly 100 of the present application.
In the cover plate assembly 100 provided in this embodiment, the concave portion 113 is disposed on the cover plate 110, and the light shielding layer 120 is disposed in the concave portion 113 and covers the surface of the concave portion 113, so that bubbles generated between the adhesive layer 130 and the light shielding layer 120 due to the light shielding layer 120 protruding from the cover plate 110 can be avoided or reduced, and the generated bubbles can be shielded by the light shielding layer 120, thereby improving the display effect of the display panel.
The surface of the recess 113 may be a curved surface protruding away from the adhesive layer 130 to facilitate the preparation of the recess 113. In other embodiments, the second surface 112 extends from the light-transmitting region B to the light-shielding region a, the recess 113 includes a bottom surface 1131 and a side surface 1132, the bottom surface 1131 is disposed opposite to the second surface 112, the side surface 1132 connects the bottom surface 1131 and the first surface 111, and the light-shielding layer 120 is attached to the side surface 1132 and the bottom surface 1131.

In the light-transmitting region B, light emitted from the second surface 112 to the bottom surface 1131 and the side surface 1132 is blocked by the light-shielding layer 120 attached to the side surface 1132 and the bottom surface 1131, and cannot pass through the concave portion 113. The light-shielding layer 120 is attached to the bottom surface 1131 and the side surface 1132, respectively, so that the connection between the light-shielding layer 120 and the first surface 111 is smooth, even if bubbles are generated between the cover plate 110 and the adhesive layer 130, the bubbles are only generated on the side of the light-shielding layer 120 away from the cover plate 110, and the bubbles can be shielded by the light-shielding layer 120 attached to the side surface 1132 and the bottom surface 1131. Because bottom surface 1131 and side 1132 are all sheltered from by light shield layer 120 for light can not be penetrated out through bottom surface 1131 and side 1132, thereby increase the user and can not observe the visual angle of bubble, reduce the influence of bubble to the display effect. It will be understood by those skilled in the art that the second surface 112 may be a plane, and the recess 113 has a bottom surface 1131 disposed opposite to the second surface 112, so that the bottom surface 1131 is also a plane, the flat bottom surface 1131 is more easily attached to the light shielding layer 120, and the light shielding layer 120 attached to the bottom surface 1131 is more flat, thereby reducing the possibility of bubbles being generated between the light shielding layer 120 and the adhesive layer 130.
The bottom surface 1131 and the side surfaces 1132 may be both flat surfaces, and the bottom surface 1131 and the side surfaces 1132 may be connected at a right angle or an obtuse angle.

The position where the bubbles are generated between the light-shielding layer 120 and the laminating layer 130 is located at the step structure and the bubbles are smaller, so that the light-shielding layer 120 can well shield the bubbles.
In some embodiments, the width direction X is a width direction from the light-shielding region a to the light-transmitting region B, and the direction from the second surface 112 to the first surface 111 is a first direction Y, and the width of the projection of the plurality of sub-light-shielding layers 120 on the adhesion layer 130 gradually decreases.
The width of the projection of the first sub-light shielding layer 121 on the adhesion layer 130 is greater than the width of the projection of the second sub-light shielding layer 122 on the adhesion layer 130. The width of the projection of the sub-shading layer close to the second surface 112 on the bonding layer 130 is the largest, and in this case, even if bubbles are generated in other layers far from the second surface 112, the sub-shading layer close to the second surface 112 has a larger width, and can also sufficiently block the bubbles.
