Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The folding display screen usually comprises display module assembly and the screen packaging layer that is used for encapsulating the display module assembly, and in order to make folding display screen can realize folding expansion function, display module assembly and screen packaging layer all adopt flexible material to make. In a folded state, the display module has a certain thickness, so that a folded area of the folded display screen can be in a U shape; and in the process of changing from the folded state to the unfolded state, the folded area is restored to be flat from the U-shaped.
However, due to the material properties of the screen encapsulation layer, the folded area still has slight protrusions after the folded display screen is changed from the folded state to the unfolded state, and the slight protrusions of the folded area are more obvious in the aspect of the user's view and feel in contrast to the flat non-folded area. Moreover, as the service time of the folding display screen increases, the convex condition of the folding area becomes more obvious.
In order to solve the above problem, in the foldable display screen provided by the embodiment of the present disclosure, an additional screen layer is additionally added on a screen encapsulation layer, so that light is reflected to different directions by the additional screen layer, and/or the flatness of a folding area is restored by the additional screen layer, thereby reducing the influence of the unevenness of the folding area on the user's appearance. The following description will be made by using exemplary embodiments.
Referring to fig. 1, a schematic structural diagram of a foldable display screen according to an exemplary embodiment of the present disclosure is shown. This folding display screen includes: a display module 110, a screen packaging layer 120 and a screen additional layer 130.
The display module 110 is used for displaying images. The display module 110 can be an OLED module (without backlight) or an LCD module (with backlight) according to the display principle. The embodiment of the disclosure does not limit the specific type of the display module 110 and the specific structure thereof.
Optionally, as shown in fig. 1, the display module 110 is made of a flexible material and includes at least one first folding area 111, and when the foldable display screen is folded, the first folding area 111 deforms.
Optionally, when the foldable display screen further has a touch function, the display module 110 may further have a touch module embedded therein, which is not limited in this embodiment.
The screen encapsulation layer 120 is disposed above the display module 110 and is used for encapsulating the display module 110.
Unlike the conventional hard screen in which glass, sapphire or resin is used as the screen encapsulation layer, the screen encapsulation layer 120 of the foldable display screen is made of a flexible material. Meanwhile, the screen packaging layer 120 has good abrasion resistance, light transmittance and foldability, thereby meeting the requirements of folding and displaying.
For example, the screen encapsulation layer 120 is a PI film.
As shown in fig. 1, the screen packaging layer 120 includes at least one second folding region 121, and the second folding region 121 of the screen packaging layer 120 corresponds to the first folding region 111 of the display module 110, that is, when the foldable display screen 100 is folded, the first folding region 111 and the corresponding second folding region 121 are deformed together.
As shown in fig. 1, the upper layer of the screen encapsulation layer 120 is also provided with a screen additional layer 130. Optionally, the screen additional layer 130 is a film attached to the surface of the screen packaging layer 120, or a coating coated on the surface of the screen packaging layer 120, and the screen additional layer 130 is made of a transparent material.
In one possible embodiment, the additional screen layer 130 is used to reflect the light projected onto the foldable display screen to different directions, i.e. the light projected onto the foldable display screen is diffusely reflected on the surface of the additional screen layer 130. After the screen additional layer 130 is added, when a user watches the folding display screen, because the light projected on the folding display screen enters the eyes of the user after diffused emission occurs on the screen additional layer 130, compared with the case that the screen additional layer 130 is not added, the light enters the eyes of the user after specular reflection occurs on the screen packaging layer 120, the perception degree of the user on the uneven folding area is reduced, and therefore the influence of the uneven folding area on the user's perception is reduced.
In another possible embodiment, the additional screen layer 130 has an automatic repairing function, and after the additional screen layer 130 is folded due to folding, the second folded area is restored to be flat while the folding is repaired.
In summary, in this embodiment, the additional screen layer is added on the upper layer of the screen packaging layer of the foldable display screen, so that the light projected onto the foldable display screen is reflected to different directions by using the principle of diffuse reflection, and thus the perception degree of the uneven area on the foldable area when the user watches the foldable display screen is reduced, and/or the uneven area on the foldable area is repaired by using the additional screen layer, and the flatness of the foldable area on the screen packaging layer is restored, so that the influence of the unevenness of the foldable area on the user's perception is avoided.
In order to reflect the light projected onto the foldable display screen in different directions, in one possible embodiment, the upper surface of the screen additional layer 130 has a granular feel, and the screen additional layer 130 reflects the projected light in different directions through the upper surface. Illustratively, as shown in FIG. 2, the upper surface 131 of the screen additive layer 130 has a grainy feel.
Regarding the manner of forming the screen additional layer 130, in one possible embodiment, the screen additional layer 130 is a first coating layer coated on the upper surface of the screen packaging layer 120, and the surface of the first coating layer has a granular feel.
Optionally, in the process of producing the folding display screen, after the display module is packaged by the screen packaging layer, a layer of high diffuse reflection coating is further formed on the upper surface of the screen packaging layer by a coating process, microscopic particles are uniformly distributed on the surface of the high diffuse reflection coating, and light rays are projected behind the high diffuse reflection coating and diffuse reflection occurs on the surfaces of the microscopic particles.
In another possible embodiment, the screen additional layer 130 is a first film attached on the screen packaging layer 120, wherein the lower surface of the first film is attached to the upper surface of the screen packaging layer, and the upper surface of the first film has a granular feel.
Optionally, in the process of producing the foldable display screen, after the display module is packaged by the screen packaging layer, the lower surface of the first film is further bonded with the upper surface of the screen packaging layer by the adhesive.
Of course, besides the screen additional layer formed by the two methods, the upper surface of the screen packaging layer can also be processed by a frosting process, and the upper surface of the screen packaging layer has granular feel, so that light projected on the screen packaging layer is subjected to diffuse reflection. The embodiments of the present disclosure do not limit this.
If the additional screen layer with granular feeling on the surface is not added to the screen packaging layer 120, as shown in fig. 3, when the folding area is not flat (there is a protrusion), the light is reflected into the eyes of the user along the same direction after being projected onto the non-folding area (i.e. flat area), and the reflection direction of the light projected onto the folding area is shifted, so that the user can easily detect the non-flat area on the folding display screen.
After the screen additional layer 130 with a granular feeling on the surface is added on the screen packaging layer 120, as shown in fig. 4, since the light projected on the screen additional layer 130 enters the eyes of the user along different directions after being diffusely reflected, even if the folding area is uneven, the user cannot easily perceive the folding area visually, and the influence of the uneven folding area on the user's feeling is reduced.
In other possible embodiments, the additional screen layer 130 may also be a transparent medium doped with a diffuse reflective material (the upper surface of the additional screen layer 130 is smooth). Such as a transparent gel doped with highly diffusely reflective nanomaterials. The light projected on the additional screen layer 130 is reflected by the high diffuse reflection nano material and enters the human eyes of the user. The embodiments of the present disclosure do not limit this.
In order to enable the folded area to restore to be flat after being unfolded, in a possible embodiment, the screen additional layer is made of a self-healing material, and the screen additional layer is used for repairing the crease and restoring the flatness of the screen packaging layer at the second folded area when the folded display screen is in an unfolded state.
Optionally, the self-healing material is a copolymer material obtained by copolymerizing methyl methacrylate and n-butyl acrylate. The present embodiment is described by taking the self-healing material as an example, but the present invention is not limited to this.
Regarding the manner of forming the screen additional layer, in a possible embodiment, the screen additional layer is a second coating layer coated on the upper surface of the screen packaging layer, and the second coating layer is made of a self-healing material.
Optionally, in the process of producing the folding display screen, after the display module is encapsulated by the screen encapsulating layer, a self-healing coating is formed on the upper surface of the screen encapsulating layer by using a self-healing material through a coating process.
In another possible embodiment, the screen additional layer is a second film attached above the screen packaging layer, the lower surface of the second film is attached to the upper surface of the screen packaging layer, and the second film is made of a self-healing material.
Optionally, in the process of producing the foldable display screen, after the display module is packaged by the screen packaging layer, the lower surface of the second film is further bonded with the upper surface of the screen packaging layer by the adhesive.
Alternatively, since the non-folded region of the folded display screen does not generate an uneven region due to the folding, the screen additional layer 130 is only disposed above the second folded region 121 in order to reduce the manufacturing cost of the folded display screen. For example, the second coating is applied only above the second folding area 121 during the production process, or a second film is attached only above the second folding area 121.
Of course, except for forming the screen additional layer by using the above two methods, a self-healing material may also be added in the process of producing the screen packaging layer 120, so that the screen packaging layer 120 itself has a self-healing function, which is not limited in this embodiment.
As shown in fig. 5, the screen additional layer 130 and the screen encapsulation layer 120 in the folding region both generate a protrusion (a crease) due to folding, and when the screen additional layer 130 repairs the crease through the self-healing capability, the screen additional layer 130 and the screen encapsulation layer 120 are tightly combined, so that the screen additional layer 130 can drive the screen encapsulation layer 120 below to restore to be flat.
In order to visually reduce the perception of the uneven area by the user and restore the uneven area to be flat, in one possible embodiment, the screen additional layer 130 is made of a self-healing material, and the upper surface of the screen additional layer 130 has a granular feel.
After the light is projected on the upper surface of the screen additional layer 130, the light is reflected in different directions through diffuse reflection, the perception degree of a user to an uneven area is reduced, and meanwhile, when the folding display screen is in an unfolding state, the screen additional layer 130 repairs creases through self-healing capacity and restores the flatness of a screen packaging layer at a second folding area.
Optionally, the screen additional layer 130 may be a third coating coated on the upper surface of the screen packaging layer 120 (the upper surface of the third coating has granular feel and is made of self-healing material); alternatively, the screen additional layer 130 is a third film attached above the screen packaging layer 120, wherein a lower surface of the third film is attached to an upper surface of the screen packaging layer, and the upper surface of the third film has granular sensation and is made of a self-healing material.
Fig. 6 is a schematic structural diagram of a folding screen terminal according to an exemplary embodiment of the present disclosure. The folding screen terminal can be a folding screen mobile phone, a folding screen tablet computer, a folding screen electronic book or a folding screen display and the like.
As shown in fig. 6, in the folded state, the folding area 610 of the folding screen terminal is U-shaped. After the foldable display screen provided by the above embodiments is configured, the problem of unevenness of the folded area 610 after the display screen is unfolded can be solved.
It should be noted that, this embodiment is only described by taking the case that the folding screen terminal includes one folding region (i.e., a two-fold structure), and in other possible embodiments, the folding screen terminal may include at least two folding regions (i.e., a three-fold structure and above); moreover, the folding screen terminal can be realized to be an inner folding screen terminal (the screen is not exposed in the folding state) or an outer folding screen terminal (the screen is exposed in the folding state), and the folding direction can be transverse folding and/or longitudinal folding, which is not limited by the disclosure.
