The disclosed embodiment provides a display module. As shown in fig. 1, the display module may include a flexible display panel 1, a first magnetic structure 2, and a second magnetic structure 3, wherein:
the first magnetic structure 2 is fixed to the backlight side of the flexible display panel 1. The second magnetic structure 3 is located at a side of the first magnetic structure 2 away from the flexible display panel 1. The second magnetic structure 3 is capable of applying an attractive and/or repulsive force to the first magnetic structure 2. Wherein at least one of the first magnetic structure 2 and the second magnetic structure 3 is an electromagnetic structure.
In the display module according to the embodiment of the present disclosure, the first magnetic structure 2 is fixed on the backlight side of the flexible display panel 1, and the second magnetic structure 3 is located on a side of the first magnetic structure 2 away from the flexible display panel 1; on one hand, as shown in fig. 2, the flexible display panel 1 may be protruded outwards by applying a repulsive force to the first magnetic structure 2 through the second magnetic structure 3 to form a 3D dynamic display effect; on the other hand, as shown in fig. 3, the second magnetic structure 3 applies an attractive force to the first magnetic structure 2, so that the flexible display panel 1 can be recessed, and a 3D dynamic display effect can be formed.
The following describes each part of the display module according to the embodiment of the present disclosure in detail:
as shown in fig. 1, the flexible display panel 1 may include a substrate, an array substrate, and a light emitting layer. The substrate may be a flexible substrate, and the material thereof may be Polyimide (PI) or the like. The specific area of the substrate can be provided with holes so that the substrate has certain deformability, and the holes can be in a straight shape or in an I shape. The array substrate may be provided at one side of the substrate. The array substrate may include a plurality of thin film transistors distributed in an array. The light emitting layer can be arranged on one side of the array substrate far away from the substrate. The light emitting layer may be an OLED light emitting layer, and of course, may also be an LED light emitting layer, but the disclosure is not limited thereto. Taking the light emitting layer as an OLED light emitting layer as an example, the light emitting layer may include an anode, a cathode, and an organic electroluminescent material layer. The anode and the cathode are oppositely disposed, and the organic electroluminescent material layer may be located between the anode and the cathode. The side of the light-emitting layer remote from the substrate may be provided with an encapsulation layer. The encapsulation layer may be a thin film encapsulation layer (TFE), which may include a first inorganic encapsulation layer, an organic layer, and a second inorganic encapsulation layer in a stacked arrangement. The material of the first inorganic encapsulation layer may be SiON or the like. The material of the organic layer may be an acrylic material, etc. The material of the second inorganic encapsulation layer may be SiN or the like. In addition, the present disclosure also requires a corresponding side encapsulation at the substrate opening to improve reliability. In addition, a flexible protective film 6 can be arranged on the side of the substrate back to the luminescent layer, and can be a soft film such as PO, TPU and the like, and can also be a film material such as PET, PI and the like with holes, so that a certain tensile deformation capability is ensured, and the thickness of the flexible protective film can be 30-150 μm.
Furthermore, as shown in fig. 1, a side of the flexible display panel 1 away from the first magnetic structure 2 may be provided with a cover plate 5. The cover plate 5 may be made of a flexible material, such as thermoplastic polyurethane elastomer (TPU), and the surface of the cover plate 5 may be treated to prevent fingerprints and glare. The thickness of the cover plate 5 may be 50 μm to 200 μm. In other embodiments of the present disclosure, the material of the cover plate 5 may be a material with variable modulus. The variable modulus material refers to: the material may be of variable modulus under certain optical, electrical or thermal conditions, for example, the variable modulus material may be stretchable PET. The stretchable PET has higher modulus in a normal state and certain surface hardness; the stretchable PET becomes soft under a temperature stimulus, for example, a high temperature stimulus of 80 ℃ or more; when the temperature is reduced, the stretchable PET returns to a hard state; with the arrangement, when the display module is converted from the flat display state to the 3D dynamic display state, the modulus of the cover plate 5 can be changed through external stimulation (light, electricity or heat) so as to deform the cover plate; after the display module enters the 3D display state, the external stimulation to the cover plate 5 can be cancelled, so that the cover plate 5 keeps the 3D dynamic display form.
As shown in fig. 1 to 3, the first magnetic structure 2 is fixed on the backlight side of the flexible display panel 1. The first magnetic structure 2 may be fixed to the flexible protective film 6. The first magnetic structure 2 may include a first support layer 201 and a first magnetic body 202. This first supporting layer 201 can be flexible material, for example bubble soft materials such as cotton, silica gel, rubber, so set up, can play the effect of buffering protection on the one hand, and on the other hand can play the effect of eliminating the die mark. The first support layer 201 may have the same size as the flexible display panel 1. The thickness of the first support layer 201 may be 50 μm to 200 μm, for example 50 μm, 100 μm, 160 μm, 200 μm, and the like. The material of the first magnetic body 202 may include a heat dissipation material, which solves the problem that a common heat sink cannot be deformed and integrated in a 3D dynamic display module. The heat dissipation material may be a metal material, but is not limited thereto, and may also be a non-metal material, such as a graphite sheet, a thermal grease, and the like. The first magnetic body 202 may be disposed on a side of the first supporting layer 201 away from the flexible display panel 1, that is, the first supporting layer 201 may be attached to a backlight side of the flexible display panel 1. Therein, the present disclosure may bond the first support layer 201 to the backlight side of the flexible display panel 1. In addition, the first magnetic body 202 may cover all regions of the first support layer 201, that is, by controlling the movement of the first magnetic body 202, all regions of the flexible display panel 1 may be controlled to perform 3D dynamic display. Of course, the first magnetic body 202 may be disposed in a partial region of the first support layer 201, that is, only a partial region of the flexible display panel 1 is controlled to perform 3D dynamic display by controlling the movement of the first magnetic body 202; for example, the first supporting layer 201 includes a first supporting region, the first magnetic body 202 is only disposed in the first supporting region, and the first magnetic body 202 is not disposed in the region other than the first supporting region.
As shown in fig. 1 to 3, the second magnetic structure 3 is located on a side of the first magnetic structure 2 away from the flexible display panel 1. As shown in fig. 4, the second magnetic structure 3 can apply a repulsive force to the first magnetic structure 2, so that the first magnetic structure 2 is far away from the second magnetic structure 3, and a part of the region of the flexible display panel 1 is raised; as shown in fig. 5, the second magnetic structure 3 can also apply an attractive force to the first magnetic structure 2, so that the first magnetic structure 2 is close to the second magnetic structure 3, and a partial region of the flexible display panel 1 is recessed; of course, the flexible display panel 1 can also be in a flat display state by controlling the acting force between the first magnetic structure 2 and the second magnetic structure 3. Wherein, at least one of the first magnetic structure 2 and the second magnetic structure 3 is an electromagnetic structure, so as to control the acting force between the first magnetic structure 2 and the second magnetic structure 3 by controlling the current, even cancel the acting force between the first magnetic structure 2 and the second magnetic structure 3. The second magnetic structure 3 may include a second supporting layer 301 and a second magnetic body 302 disposed on the second supporting layer 301. The second magnetic body 302 may include the heat dissipation material, which solves the problem that the conventional heat dissipation plate cannot be deformed and integrated in the 3D dynamic display module. The second magnetic body 302 may be disposed on a side of the second support layer 301 close to the flexible display panel 1. The material of the second support layer 301 may include at least one of a polymer, glass, and metal. The high polymer can be PMMA, PC, PI and other high polymers with high modulus and certain support property. The metal may be Cu, Al, etc. The thickness of the second support layer 301 may be 30 μm to 500 μm, such as 30 μm, 200 μm, 360 μm, 500 μm, and the like. In the example where the first magnetic substance 202 is provided over the entire surface region of the first support layer 201, the second magnetic substance 302 may be provided over the entire surface region of the second support layer 301. Taking the first magnetic body 202 disposed in the first support region of the first support layer 201 as an example, the second magnetic body 302 may be disposed in a region of the second support layer 301 corresponding to the first support region.
One of the first magnetic body 202 and the second magnetic body 302 is a permanent magnet, and the other is an electromagnet. For example, the first magnetic body 202 is a permanent magnet, and the second magnetic body 302 is an electromagnet. Of course, the first magnetic body 202 may be an electromagnet, and the second magnetic body 302 may be a permanent magnet. The two poles of the permanent magnet are distributed along the thickness direction of the flexible display panel 1. The length of the permanent magnet may be 30 μm-150 μm, such as 30 μm, 50 μm, 80 μm, 150 μm, etc., in the thickness direction of the flexible display panel 1. The distance between two adjacent permanent magnets in a direction perpendicular to the thickness direction of the flexible display panel 1 may be 0.2mm-20mm, such as 0.2mm, 5mm, 13mm, 20mm, etc. The length of the permanent magnet may be 0.1mm-10mm, such as 0.1mm, 3mm, 7mm, 10mm, etc., in a direction perpendicular to the thickness direction of the flexible display panel 1. The orthographic projection of the permanent magnet on the flexible display panel 1 is a polygon such as a triangle, a quadrangle, a hexagon, etc., and of course, the orthographic projection may be a circle. Taking the orthographic projection of the permanent magnet as a quadrangle as an example, the orthographic projection of the permanent magnet is a square; in the direction perpendicular to the thickness direction of the flexible display panel 1, the distance between two adjacent permanent magnets refers to the distance between the sides of two adjacent squares; the length of the permanent magnet refers to the side length of a square in the direction perpendicular to the thickness direction of the flexible display panel 1; the four corners of the quadrilateral may also have rounded corners.
The number of the permanent magnets may be plural, and the plural permanent magnets are uniformly distributed in a direction perpendicular to the thickness direction of the flexible display panel 1. As shown in fig. 7, taking the first magnetic body 202 as an example of a permanent magnet, the plurality of permanent magnets are uniformly distributed, that is, the plurality of first magnetic bodies 202 are uniformly distributed on the first supporting layer 201. The material of the permanent magnet may be a magnetic metal such as iron, cobalt, or nickel, or may be an alloy material of iron, cobalt, or nickel. The permanent magnet can move under the action of magnetic force to realize 3D dynamic display, and meanwhile, the permanent magnet can also play roles of heat dissipation, shading and the like, so that the problem that a common radiating fin cannot deform and cannot be integrated in a 3D dynamic display module is solved. The permanent magnet can be prepared by vacuum sputtering and etching, and can also be prepared by calendaring, etching and transfer printing.
As shown in fig. 4, the electromagnet includes a coil 3021, and an axis of the coil 3021 may be parallel to a thickness direction of the flexible display panel 1. Of course, the electromagnet may further include an iron core 3022 perforated in the coil 3021. The coil 3021 of each electromagnet may be connected to an external circuit to receive an electrical signal. The number of the electromagnets may be plural, and the plural electromagnets are uniformly distributed in a direction perpendicular to the thickness direction of the flexible display panel 1. Taking the second magnetic body 302 as an electromagnet as an example, the plurality of electromagnets are uniformly distributed, that is, the plurality of second magnetic bodies 302 are uniformly distributed on the second support layer 301. Further, the plurality of electromagnets may constitute a plurality of electromagnet groups, each of which may include one or more electromagnets. For an electromagnetic group comprising a plurality of electromagnets, the directions of the magnetic fields generated by the plurality of electromagnets in the electromagnetic group are the same. As shown in fig. 6, the directions of the magnetic fields generated by different electromagnetic groups may be different for different electromagnetic groups, so that the second electromagnetic structure may not only apply a repulsive force to the first electromagnetic structure, but also apply an attractive force to the first electromagnetic structure, thereby protruding a partial region of the flexible display panel 1 outwards and recessing another partial region of the flexible display panel 1 inwards.
As shown in fig. 1 to 3, the display module according to the embodiment of the disclosure may further include a spacer layer 4. The spacer layer 4 may be located between the first magnetic structure 2 and the second magnetic structure 3. Taking the example that the first magnetic body 202 is disposed on the side of the first supporting layer 201 facing away from the flexible display panel 1 and the second magnetic body 302 is disposed on the side of the second supporting layer 301 facing the flexible display panel 1, the second magnetic body 302 may be fixed between the second supporting layer 301 and the spacing layer 4; the first magnetic body 202 can contact the spacer layer 4 under the attractive force of the second magnetic structure 3, and when the attractive force is large, the first magnetic structure 2 can press the spacer layer 4 to form a recess on the spacer layer 4; meanwhile, the first magnetic body 202 can be separated from the spacer layer 4 by the repulsive force of the second magnetic structure 3. The material of the spacing layer 4 can be a soft polymer material or a glue material which has no influence on the magnetic force, such as PO, TPU, PET, acryl, silica gel, and the like. The thickness of the spacer layer 4 may be 10 μm-150 μm, e.g. 10 μm, 50 μm, 80 μm, 150 μm, etc.
The embodiment of the disclosure also provides a display method of the display module. The display module described in any of the above embodiments can be used in the display method. The display method may include: applying a repulsive force to the first magnetic structure 2 through the second magnetic structure 3 to make the flexible display panel 1 protrude outward; alternatively, an attractive force is applied to the first magnetic structure 2 through the second magnetic structure 3 to generate a depression of the flexible display panel 1. The display module adopted by the display method of the embodiment of the disclosure is the same as the display module in the embodiment of the display module, so that the display method has the same beneficial effects, and the disclosure is not repeated herein.
The embodiment of the disclosure also provides a display device. The display device may include the display module according to any one of the above embodiments. The display device can be a television, a mobile phone and the like. The display module included in the display device of the embodiment of the present disclosure is the same as the display module in the embodiment of the display module, and therefore, the display device has the same beneficial effects, and the disclosure is not repeated herein.
Although the present disclosure has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the disclosure.
