Detailed Description
Features and exemplary embodiments of various aspects of the application are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
The inventor finds that the reason why the existing rollable display module cannot well consider both inner and outer rolls is that: the flexible display panel in the rollable display module comprises a packaging layer, wherein the packaging layer is used for isolating water and oxygen, and preventing the water and oxygen from invading the display panel to influence the performance of the display panel. The packaging layer comprises an inorganic material layer, and the flexibility of the inorganic material layer is poor. After the rollable display module is manufactured, the positions of the packaging layer and the neutral layer of the rollable display module are determined, and in general, the relative position of the packaging layer and the neutral layer of a rollable display panel is only suitable for being an outer roll or an inner roll, wherein the neutral layer is the part with the smallest stress received after the rollable display panel is bent, so that the probability of damaging the packaging layer can be reduced by setting the position of the packaging layer to be close to the position of the neutral layer after the packaging layer is curled and to be positioned at one side of the neutral layer towards the inner side of the curl. Since the relative position of the encapsulation layer and the neutral layer of a rollable display panel is only suitable for being rolled up or rolled up, if both inner and outer rolling are performed, when the encapsulation layer is located on the side of the neutral layer facing the outer side of the curl, the encapsulation layer is easily damaged, such as cracks, due to tensile stress, so that the service life of the curl module is reduced. Based on the research on the problems, the inventor provides a display module and a display device to improve the service life of the display module and the display device.
For a better understanding of the present application, a display module and a display device according to embodiments of the present application are described in detail below with reference to fig. 1 to 9.
Referring to fig. 1, an embodiment of the present application provides a display module 1, where the display module 1 includes a flexible display panel 10 and a neutral layer adjusting mechanism 11, the neutral layer adjusting mechanism 11 is located at a side of the flexible display panel 10 facing away from a light emitting surface, and includes a first film layer 111 and a second film layer 112 stacked along a thickness direction of the flexible display panel 10, and a fixing strength between the first film layer 111 and the second film layer 112 is adjustable to adjust a neutral layer position of the display module 1.
The display module 1 provided by the application comprises a neutral layer adjusting mechanism 11 arranged on one side of the flexible display panel 10, which is far away from the light emitting surface, wherein the neutral layer adjusting mechanism 11 comprises a first film layer 111 and a second film layer 112, and the first film layer 111 and the second film layer 112 are laminated along the thickness direction of the flexible display panel 10. The fixing strength between the first film layer 111 and the second film layer 112 is adjustable, specifically, the display panel includes a preset film layer, and before the display panel is rolled in (or folded in), the fixing strength between the first film layer 111 and the second film layer 112 can be adjusted to be greater, so that the position of the neutral layer of the display module 1 moves down, and the preset film layer is located above the vicinity of the neutral layer (located on the side of the neutral layer facing the light-emitting surface of the display panel), so that the tensile stress suffered by the preset film layer in the rolling process is reduced, and the damage such as cracks and the like is prevented. Before the display panel is rolled (or folded) outwards, the fixing strength of the first film layer 111 and the second film layer 112 can be reduced, so that the position of the neutral layer of the display module 1 moves upwards relative to that of the inner roll, the preset film layer is located below the vicinity of the neutral layer (located on the side, away from the light-emitting surface of the display panel, of the neutral layer), the tensile stress suffered by the preset film layer in the rolling process is reduced, and damage such as cracks and the like is prevented. Wherein, as shown in fig. 2, the inner coil is: the display panel is curled from one side away from the light emitting surface to one side of the light emitting surface, so that the light emitting surface of the display panel is positioned in the curled display module 1. As shown in fig. 3, the outer wrap is: the light-emitting surface of the display panel is curled from one side of the light-emitting surface to the other side of the light-emitting surface, so that the light-emitting surface of the display panel is positioned outside the curled display module 1. In the display module 1 provided by the application, the position relation between the set film layer in the display panel and the neutral layer of the display module 1 can be adjusted, so that the display module 1 can be rolled inwards and outwards, and can be folded inwards and outwards, and the service life of the display module 1 is also considered.
As shown in fig. 1, the display module 1 includes a neutral layer adjusting mechanism 11, a first optical adhesive layer 15, a back support layer 16, a flexible display panel 10, a polarizer 14, a second optical adhesive layer 13, and a flexible cover plate 12 that are stacked, and may further include other film structures, which are not particularly limited in the present application. As shown in fig. 4, the flexible display panel 10 includes an array substrate 101, a light emitting device layer 102 formed on the array substrate 101, and a packaging layer 103 formed on a side of the light emitting device layer 102 away from the array substrate 101, where the packaging layer 103 is used for protecting the light emitting device layer 102, so as to prevent water and oxygen from invading the light emitting device layer 102 to affect the display effect.
The above-mentioned preset film layer may be the encapsulation layer 103 in the flexible display panel 10, where the encapsulation layer 103 includes an inorganic material layer, and because the inorganic material layer has poor flexibility and is easy to break when being subjected to tensile stress, the inorganic material layer is placed on one side of the neutral layer, which is located on the inner side after being curled, or is overlapped with the neutral layer, so that the tensile stress to which the encapsulation layer 103 is subjected can be reduced, thereby protecting the encapsulation layer 103 from being damaged.
In the display module 1, the second film layer 112 may be located at a side of the first film layer 111 away from the flexible display panel 10, so as to reduce the fixing strength of the first film layer 111 and the second film layer 112, and increase the fixing strength of the first film layer 111 and the second film layer 112, and the second film layer 112 and the first film layer 111 are easier to generate relative displacement, thereby changing the position of the neutral layer.
In one possible embodiment, one of the first film layer 111 and the second film layer 112 comprises an electromagnet, and the other comprises a magnetic material.
In the above embodiment, the first film 111 and the second film 112 are fixed by magnetic attraction, and the first film 111 and the second film 112 are both electromagnets, or one of the first film 111 and the second film 112 is an electromagnet, and the other is a magnetic material that can be attracted by the electromagnet, so that the fixing strength between the first film 111 and the second film 112 can be adjusted by adjusting the magnetic force of the electromagnet. Specifically, the magnitude of the magnetic force of the electromagnet may be adjusted by adjusting the magnitude of the current through the electromagnet.
The neutral layer adjusting mechanism 11 in the above embodiment has a simple structure, is convenient to operate, and has a low overall thickness of the display module 1. Meanwhile, when only the first film 111 close to the flexible display panel 10 is provided to meet the unidirectional curling requirement (for example, only the outer roll), and the user only has the unidirectional curling requirement, the second film 112 can be removed, so as to further simplify the overall structure of the display module 1, and facilitate the realization of light and thin.
In another possible embodiment, as shown in fig. 5, the neutral layer adjusting mechanism 11 further includes an adjusting component 113 located between the first film layer 111 and the second film layer 112, where the adjusting component 113 is used to adjust the fixing strength between the first film layer 111 and the second film layer 112.
In the above embodiment, by providing the dedicated adjustment assembly 113, only the fitting can be replaced after the damage, thereby saving the cost. In the prior art, the display module 1 includes a metal supporting layer, a first optical adhesive layer, a back supporting layer, a flexible display panel, a polarizer 14, an optical adhesive, a flexible cover plate, and other film layers, and in the above embodiment, a special adjusting component 113 may be further disposed between the first film layer 111 and the second film layer 112 to adjust the fixing strength between the first film layer 111 and the second film layer 112, so that the metal supporting layer is used as the first film layer 111 on the basis of not changing the design of the existing display module 1, and the second film layer 112 and the adjusting component 113 are newly added on one side of the first film layer 111 away from the flexible display panel 10, thereby greatly saving the production cost.
In one possible embodiment, the adjustment assembly 113 includes an electromagnetic adjustment assembly 114, and the magnetic force of the electromagnetic adjustment assembly 114 is adjustable.
At least one of the first film layer 111 and the second film layer 112 is made of a magnetic material.
In the above embodiment, the adjusting component 113 is an electromagnetic adjusting component 114, at least one of the first film 111 and the second film 112 is made of a magnetic material, and when only one of the first film 111 and the second film 112 is made of a magnetic material, the electromagnetic adjusting component 114 is fixed on one of the non-magnetic materials in the first film 111 and the second film 112, so that the fixing strength of the first film 111 and the second film 112 is adjusted by adjusting the magnetic force between the magnetic material and the electromagnetic adjusting component 114. When the first film 111 and the second film 112 are both magnetic materials, the electromagnetic adjusting component 114 can be fixed to either one.
In a possible embodiment, as shown in fig. 6, the electromagnetic adjusting assembly 114 includes an electromagnetic block disposed on the whole surface, and the front projection of the electromagnetic block on the first film 111 covers the first film 111, and the fixing strength of each area in the first film 111 and the second film 112 can be uniformly adjusted by adjusting the magnetic force of the electromagnetic block, so that the protection effect on each area of the preset film is better.

The plurality of electromagnetic blocks are distributed in an array, and the first electromagnetic blocks 1141 and the second electromagnetic blocks 1142 are alternately distributed, so that when the fixed strength of the first film layer 111 and the second film layer 112 is required to be reduced, only each first electromagnetic block 1141 works, and the second electromagnetic block 1142 does not work; when the fixed strength of the first film 111 and the second film 112 is desired to be increased, each first electromagnetic block 1141 and each second electromagnetic block 1142 are enabled to operate. The above adjustment mode is simple by adjusting the density of the electromagnetic block in the working state to adjust the fixing strength of the first film 111 and the second film 112.
