Detailed Description
The technical solutions of the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present invention, fall within the scope of protection of the present invention.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present invention may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. In addition, in the specification and claims, "and/or" means at least one of the electrically connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The display module disclosed by the embodiment of the invention is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
FIG. 1 is a schematic cross-sectional view of a display module; fig. 2 is a schematic top view of another display module according to an embodiment of the present invention, in which the bending extension portion is in an unfolded state (corresponding to before bending);
as shown in fig. 1, a display module disclosed in an embodiment of the present invention includes: the main screen body 110, the bending extension 120, the auxiliary functional layer 210 and the light leakage preventing structure 260.
The main screen 110 has a display area 111, a bezel area 112 disposed around the display area 111, and a first alignment mark 130 is formed at a position of the main screen 110 corresponding to the bezel area 112.
The bending extension portion 120 extends from an edge of the main screen body 110 corresponding to the first alignment mark 130 and is formed by bending, a width (a width direction corresponds to the first direction, a direction) of the bending extension portion 120 is smaller than a width of the edge of the main screen body 110 extending out of the bending extension portion 120, and the second alignment mark 150 is formed on the bending extension portion 120.
The auxiliary functional layer 210 is disposed on a side of the main screen body 110 opposite to the light emitting side, the auxiliary functional layer 210 includes at least one light shielding sub-functional layer (may include a structure corresponding to 212, 213, 214 in fig. 2), and openings 211 corresponding to the first alignment marks are formed on the light shielding sub-functional layers 212, 213, 214.
The light leakage preventing structure 260 includes a denatured light shielding material denatured by a light transmitting material, and the light leakage preventing structure 260 is disposed between the main screen body 110 and the auxiliary functional layer 210 and corresponds to the position of the opening 211.
The end portion of the bending extension 120 covers a side of the auxiliary functional layer 210 facing away from the main screen body 110 and avoids the opening 211, and the first alignment mark 130 corresponds to a side of the bending extension 120 in the first direction (a direction) and is aligned with the second alignment mark 150. Preferably, the first alignment mark 130 corresponds to an outer side in the width direction (first direction, a direction) of the bending extension 120.
The light leakage preventing structure 260 may cover all of the openings 211, or may cover part of the openings 211 and all of the portions of the openings 211 corresponding to the display area 111.
Preferably, the two first alignment marks 130 and the two second alignment marks 150 are located on a plane parallel to an edge of the main screen 110 and perpendicular to the surface of the main screen 110.
The above display module assembly can be matched with the light shielding functional layer because the light leakage preventing structure 260 is correspondingly arranged at the position of the opening 211, so that the light on one side of the back surface of the main screen body is effectively prevented from affecting the normal display of the display area 111, and the abnormal point display caused by light transmission at the edge part of the display area 111 can be avoided, so that the frame area 112 is narrower, and the purpose of a narrow frame is better realized.
The inventor researches find that the reasons why dot-like display anomalies occur at the lower edge part of a display area adopting a narrow-frame display device are as follows: in order to align the bending extension portion with the main screen body, alignment marks 130 and 150 need to be formed on the frame region 112 and the bending extension portion 120, and an opening 211 needs to be provided on the auxiliary functional layer 210 to expose the alignment mark 130 of the frame region 112. The sizes of the hole and the alignment mark are limited by the precision of the manufacturing process and the equipment, so that the size of the hole and the alignment mark cannot be too small, and thus when the frame area is narrow to a certain extent and errors of the manufacturing and alignment precision accumulate to a certain extent, the situation that the hole area is overlapped with the display area can occur, and if the light leakage preventing structure 260 is not used for shielding the situation, external light rays or partial light rays emitted from the display area can be reflected by the hole wall of the hole, the bending extension part and other structures and penetrate out from the position close to the edge of the display area, so that point-shaped abnormal display is caused.
In some embodiments, the light leakage preventing structure 260 includes a first adhesive layer 262 including a denatured light shielding material 261, and the auxiliary functional layer 210 is fixed to the main screen body 110 through the first adhesive layer 262. Wherein the denatured light-shielding material covers the opening 211.
In some embodiments, the first adhesive layer 262 and the auxiliary functional layer 210 are both part of a composite auxiliary functional layer; alternatively, the first adhesive layer 262 and the auxiliary functional layer are formed as a composite auxiliary functional layer.
In some embodiments, the composite auxiliary functional layer includes a polymer layer 212, a second adhesive layer 213, and a heat dissipation layer 214 arranged on one side of the first adhesive layer 262. In some embodiments, the polymer layer 212 is a foam layer, the second adhesive layer 213 comprises a polyimide layer, and the heat sink layer 214 comprises a copper layer. The structure can make the product better realize the display property, and simultaneously, the heat dissipation performance of the product is better, thereby prolonging the service life of the product.
In some embodiments, the light shielding material described above includes at least one of an electrochromic material, a photochromic material, and a thermochromic material. For example, the photochromic material can be a UV photochromic polymer.
In some embodiments, referring to fig. 4, the light-leakage preventing structure 260 is a denatured light-shielding material disposed in the opening 211, and the denatured light-shielding material is formed by denaturation of a light-transmitting material. Accordingly, the first adhesive layer 262 for adhering the auxiliary functional layer 210 and the main screen body 110 may not contain a denatured light-shielding material. This may result in lower raw material costs for the product.
The light-transmitting material which can be used as the light-shielding material can be a UV photochromic polymer, namely a polymer containing a photochromic group in a macromolecule, which can change color under the excitation of UV light, and is usually obtained by firstly synthesizing a monomer containing the photochromic group (such as azobenzene, spirobenzopyran and the like) and then carrying out polymerization reaction or copolymerization with other monomers.
In some embodiments, referring to fig. 1 and 2, the first alignment marks 130 and the second alignment marks 160 include two, the two second alignment marks 160 are respectively disposed near one side edge of the bending extension portion 130 in the width direction (a direction in the drawing), and the two first alignment marks 130 are respectively disposed at the outer side of the bending extension portion 120 in the width direction and near the edge of the bending extension portion 120; in this case, the first alignment mark 130 is close to the bending extension 120, so alignment can be facilitated.
Preferably, the first alignment mark 130 is located on the back side of the main screen body 110, and the second alignment mark 160 may be located on the front side or the back side of the bending extension 120 (where the front side and the back side both correspond to the unfolded state of the bending extension 120, the front side corresponds to the light emitting side of the main screen body 119, and the back side corresponds to the backlight side of the main screen body 119). Wherein, when the second alignment mark 160 and the first alignment mark 130 are both located on the back surface of the bending extension portion 120, they can be manufactured in the same process (in this case, it is required that the film layer of the bending extension portion 120 is transparent as a whole); when the second alignment mark 160 is located on the front surface, the second alignment mark 160 can be more easily seen during alignment. Thereby, accurate alignment of the second alignment mark 160 with the first alignment mark 130 can be achieved.
In some embodiments, referring to fig. 1, a dimension (corresponding to s1+s4+s5) of the frame region 112 extending out of the bending extension 120 in the second direction (a width direction of the frame region 112 extending out of the bending extension 120, corresponding to the B direction in fig. 1) is less than or equal to 1.0mm, a dimension S4 of the first alignment mark 130 in the second direction is greater than or equal to 0.1mm, a dimension S5 of the first alignment mark 130 in the second direction to an outer edge of the frame region is greater than or equal to 0.1mm, and a dimension S2 of the first alignment mark 130 in the second direction to an inner side of the opening 211 toward the main screen 110 is greater than or equal to 0.2mm. Under the condition that the corresponding size meets the requirements of equipment and manufacturing precision (the size is not too small to be difficult to meet by a process), even if the open hole is partially or even completely overlapped with the display area, the abnormal display point at the edge of the display area due to light transmission of the open hole can not occur due to shielding of the light leakage prevention structure 260; that is, the openings are allowed to extend from the frame area to the display area, so that the design and manufacturing difficulty of the product are reduced, the display quality is ensured, and the narrow frame is realized.
In some preferred embodiments, please continue to refer to fig. 1, the dimension of the frame region (corresponding to s1+s4+s5) extending from the bending extension in the second direction is less than or equal to 0.9mm, the dimension of the first alignment symbol S4 in the second direction is greater than or equal to 0.15mm, the dimension S5 of the first alignment symbol from the first alignment symbol to the outer edge of the frame region in the second direction is greater than or equal to 0.15mm, and the dimension S2 of the first alignment symbol 130 from the first alignment symbol to the opening 211 toward the inner side of the main screen 110 in the second direction is greater than or equal to 0.3mm. Therefore, the design and manufacturing difficulty of the product are reduced, the display quality is guaranteed, and a narrower frame is realized.
The solution of the present invention is not limited to the above embodiment, for example, the display module may further include a polarizing layer disposed on the light emitting side of the main screen 110, an optical adhesive layer disposed on the polarizing layer, and a cover plate disposed on the optical adhesive layer.
The embodiment of the invention also provides a method for manufacturing the display module, which comprises the following steps:
the light-leakage-preventing structure 260 and the auxiliary functional layer 210 comprising at least one light-shielding sub-functional layer are arranged on the back surface of the main screen body 110, wherein the light-leakage-preventing structure 260 is arranged between the main screen body 110 and the auxiliary functional layer 210, the auxiliary functional layer 210 comprises at least one light-shielding sub-functional layer (212, 213 and 214) with light shielding property, the light-shielding sub-functional layer is provided with an opening 211 corresponding to a first alignment mark, and the light-leakage-preventing structure 260 comprises a light-transmitting material capable of forming a modified light-shielding material in a variability manner and corresponds to the position of the opening 211;
bending the bending extension part 120 to the back of the auxiliary functional layer 210, and aligning the bending extension part 120 with the main screen body 110 through the positions of the first alignment mark 130 and the second alignment mark 160;
the light-transmitting material is denatured to form a denatured light-shielding material 261.
The above method can ensure that the bending extension 120 is accurately aligned with the main screen 110.
In some embodiments, the light transmissive material is UV color-changing particles, which are irradiated with UV light from the openings on the back surface, so that the light transmissive material is denatured to form denatured light-shielding material 261. In this case, the light leakage preventing structure 260 may be a transparent material layer to which UV color-changing particles are added; further, the light leakage preventing structure 260 may be a mesh glue layer to which UV color-changing particles are added.
In some embodiments, the first adhesive layer 262 and the auxiliary functional layer 210 are both integral parts of a composite auxiliary functional layer. Alternatively, the first adhesive layer 262 and the auxiliary functional layer are formed as a composite auxiliary functional layer. Both of these cases are based on the fact that the first adhesive layer 262 is identical to the overall size of the auxiliary functional layer 210, and a composite adhesive tape can be manufactured first and then adhered to the rear surface of the main screen body 110, so that the manufacturing process can be simplified.
The embodiment of the invention also provides a display device comprising the display module.
The foregoing embodiments of the present invention are mainly described in the differences between the embodiments, and the different optimization features of the embodiments may be combined to form a preferred embodiment as long as they are not contradictory. It is clear that when the structure or material is changed, the manufacturing method needs to be correspondingly adjusted, for example, a thermochromic material is used to replace a photochromic material, and the material needs to be heated or cooled as required when the material is changed in color.
The foregoing is merely exemplary of the present invention and is not intended to limit the present invention. Various modifications and variations of the present invention will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are to be included in the scope of the claims of the present invention.
