The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
The present application is described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the present disclosure; FIG. 2 is a schematic diagram of a liquid crystal module in the display panel shown in FIG. 1; FIG. 3a is a schematic view of a flexible light-transmitting film in the display panel of FIG. 1; fig. 3b is a schematic view of the structure of the flexible light-transmitting film shown in fig. 3a without being extruded. The present application provides a display panel, which may be a liquid crystal display panel that can be used for an automotive display screen; as shown in fig. 1, the display panel may include a backlight module 1, a liquid crystal module 2, and a flexible light-transmitting film 3. The backlight module 1 is used for providing backlight and ensuring that the backlight uniformly penetrates the liquid crystal module 2.
Referring to fig. 1 and 2, the liquid crystal module 2 is disposed on the light emitting side of the backlight module 1; and the liquid crystal module 2 can bend to one side of the backlight module 1 under the action of external force to form a first deformation part 20. It will be understood by those skilled in the art that the first deformation portion 20 may cause light that should be absorbed by the upper polarizer at this location to be emitted, i.e., light leakage occurs. It can be understood that the first deformation portion 20 is not a fixed structure on the liquid crystal module 2, and when any portion of the liquid crystal module 2 is acted by an external force in the direction of the backlight module 1, a first deformation portion 20 with a bending degree positively correlated to the magnitude of the applied external force can be formed; when the liquid crystal module 2 is not subjected to external force, the first deformation portion 20 can recover deformation and disappear.
The flexible light-transmitting film 3 is disposed between the backlight module 1 and the liquid crystal module 2. The flexible light-transmitting film 3 includes a plurality of grids 31 extending in the lamination direction and arranged at intervals in the first direction X; wherein the first direction X and the lamination direction Z are perpendicular to each other.
Wherein the flexible light-transmitting film 3 is capable of generating a second deformation portion 30 under the extrusion of the liquid crystal module 2; the grid 31 of the second deformation portion 30 can be bent or deflected under the extrusion of the liquid crystal module 2, and the bent or deflected grid 31 can reflect more light emitted by the backlight module 1, so that the light transmittance of the flexible light-transmitting film 3 at the second deformation portion 30 is lower than that of other portions.
In this way, the flexible light-transmitting film 3 is arranged between the backlight module 1 and the liquid crystal module 2 to separate the backlight module 1 from the liquid crystal module 2, so that the situation that the backlight module 1 and the liquid crystal module 2 rub to scratch the display panel is avoided; meanwhile, the grille 31 which can be bent or deflected under the extrusion of the liquid crystal module 2 is arranged in the flexible light-transmitting film 3, so that when the liquid crystal module 2 is pressed and deformed, the bent or deflected grille 31 can shield part of light which can be transmitted when the second deformation part 30 is not bent, and the light transmittance of the second deformation part 30 which is bent by the flexible light-transmitting film 3 is lower than that of other parts. In this way, the first deformation portion 20 corresponding to the second deformation portion 30 in the liquid crystal module 2 can compensate the light that is excessively leaked due to deformation of the second deformation portion 30 of the flexible light-transmitting film 3, so that the occurrence of pressing light leakage of the display panel is avoided.
In a specific embodiment, the difference between the light transmitted before deformation and the light transmitted after deformation of the first deformation portion 20 of the liquid crystal module 2 is equal to the difference between the light transmitted before deformation and the light transmitted after deformation of the second deformation portion 30; so that the light leaking from the deformed first deformation portion 20 can exactly compensate the light shielded by the deformed second deformation portion 30, so that the display panel can display the picture normally. It can be understood that the first deformation portion 20 transmits more light than before deformation, and the second deformation portion 30 transmits less light than before deformation; therefore, the above-mentioned level means specifically that the absolute value of the difference between the light transmitted before and after the deformation of the first deformation portion 20 is equal to the absolute value of the difference between the light transmitted before and after the deformation of the second deformation portion 30.
In a specific embodiment, referring to fig. 1 and 3a, the flexible light-transmitting film 3 has a first surface and a second surface disposed opposite to each other in the lamination direction Z; the first surface may be disposed in contact with a surface of the liquid crystal module 2 facing the backlight module 1, and the second surface may be disposed in contact with a surface of the backlight module 1 facing the liquid crystal module 2. Specifically, under the extrusion of the liquid crystal module 2, the distance between the part of the first surface of the flexible light-transmitting film 3 located at the second deformation portion 30 and the part of the second surface is reduced, that is, the thickness of the second deformation portion 30 is reduced, so as to extrude the grille 31 located at the second deformation portion 30 and bend or deflect the grille 31.
In this embodiment, preferably, the second surface of the second deforming part 30 may not deform under the support of the backlight module 1, and only the first surface approaches the second surface under the extrusion of the liquid crystal module 2, thereby realizing the extrusion of the grid 31. Of course, in other embodiments, the second surface may also deform under the extrusion of the liquid crystal module 2, so long as the deformation degree of the second surface is smaller than that of the first surface, so that the first surface and the second surface can extrude the grid 31 to bend or deflect.
Specifically, in this embodiment, the grids 31 may be configured such that under the extrusion of the liquid crystal module 2, the middle portion of each grid 31 is bent, and the two ends of the grid 31 are inclined in the same direction, so that the grids 31 can block part of the light emitted from the backlight module 1, thereby reducing the light transmittance of the second deformation portion 30. Specifically, as shown in fig. 3a, the bending directions of the grids 31 are the same; that is, the plurality of grids 31 positioned at the second deforming part 30 are each bent in the first direction X and toward the same direction to make the distance between adjacent grids 31 more uniform, thereby making the light transmitted from the second deforming part 30 more uniform.
Of course, in other embodiments, the grille 31 may be configured to deflect in the first direction X toward the same direction under compression of the liquid crystal module 2; that is, each of the grids 31 located at the second deformation portion 30 is inclined in the same direction, so that the grids 31 can block part of the light emitted from the backlight module 1, thereby reducing the light transmittance of the second deformation portion 30.
It will be appreciated that the degree of bending or deflection of the grille 31 at different locations of the second deformation portion 30 is positively correlated with the degree of deformation at different locations of the second deformation portion 30. For example, the degree of deformation is greater at the center of the second deformation portion 30 and smaller at the edges; the degree of bending or deflection of the grill 31 at the center of the second deformation 30 is greater and the light transmittance at the center of the second deformation 30 is lower; and the degree of bending or deflection of the grill 31 at the edge of the second deformation 30 is smaller, and the light transmittance at the edge of the second deformation 30 is higher.
In the following embodiments of the present application, the case where the grill 31 of the second deformation portion 30 is provided so as to be bendable by the pressing of the liquid crystal module 2 will be described.
In combination with fig. 3a and 3b, in a specific embodiment, the flexible light-transmissive film 3 may further comprise a flexible cavity 32 and a light-transmissive liquid 33. Wherein, the flexible cavity 32 is a hollow cavity formed by surrounding flexible materials, so as to be used as a film body to hold the grille 31 and the light-transmitting liquid 33; the flexible cavity 32 is deformable by the extrusion of the liquid crystal module 2. The grids 31 may be disposed at equal intervals in the first direction X within the flexible cavity 32, and each grid 31 extends from an inner wall of one side of the flexible cavity 32 to an inner wall of the other side in the stacking direction Z; so that the flexible cavity 32 can be deformed and then simultaneously squeeze the grille 31 to form the second deformed portion 30. Specifically, in the present embodiment, the material of the flexible cavity 32 may be polyethylene terephthalate (PET), so that the flexible cavity 32 has good mechanical properties and light-transmitting properties, so as to meet the deformation requirement and the light-transmitting requirement of the flexible light-transmitting film 3. Of course, in other embodiments, the material of the flexible cavity 32 may be other materials with flexible and light-transmitting properties.
The light-transmitting liquid 33 fills between adjacent gratings 31 and fills the inner space of the flexible cavity 32; it will be appreciated that the light-transmitting liquid 33 may provide a certain mechanical property to the flexible light-transmitting film 3, so that the flexible light-transmitting film 3 has a certain stiffness and flexibility at the same time, and thus the flexible light-transmitting film 3 can deform under the extrusion of an external force and recover the deformation after the external force is removed. Specifically, the transparent liquid 33 may be a transparent non-corrosive liquid, so as to avoid the situation that the transparent liquid 33 corrodes the flexible cavity 32 to cause the transparent liquid 33 to leak. Preferably, the light-transmitting liquid 33 may be ultrapure water.
As shown in fig. 3b, in a specific embodiment, the grille 31 may further include a light-transmissive portion 311 that is transmissive to light and a light-shielding portion 312 for shielding light. It can be understood that, when the grating 31 of the second deforming portion 30 is configured to be capable of being bent under the extrusion of the liquid crystal module 2, for a certain bent grating 31, the projections of the two side portions thereof along the lamination direction Z are at least partially overlapped; therefore, each of the grids 31 is configured to have a structure in which a part transmits light and another part shields light, so that the manufacturing cost of the display panel can be reduced while satisfying the deformation shielding effect.
Preferably, the length of the light transmitting portion 311 in the lamination direction Z is the same as the length of the light shielding portion 312 in the lamination direction Z, so that the light shielding effect of the light shielding portion 312 is optimized.
Specifically, the light-transmitting portion 311 may be located at a side of the grid 31 close to the liquid crystal module 2, and the light-shielding portion 312 is located at a side of the grid 31 close to the backlight module 1. In this way, the light that is not reflected by the light shielding portion 312 can be more uniform after being transmitted through the light transmitting portion 311, so as to enhance the display effect of the display panel.
Of course, in other embodiments, the light shielding portion 312 may be located at a side of the grid 31 close to the liquid crystal module 2, and the light transmitting portion 311 is located at a side of the grid 31 close to the backlight module 1.
As shown in fig. 1, in a specific embodiment, the backlight module 1 may further include an optical film 11 for adjusting and controlling the color and brightness of the backlight to achieve a better display effect. Specifically, the optical film 11 is disposed on a surface of the backlight module 1 facing the liquid crystal module 2 and is in contact with the flexible light-transmitting film 3, so as to provide support for the flexible light-transmitting film 3; it will be appreciated that the optical film 11 is not deformed by the extrusion of the flexible light transmissive film 3, so that the flexible light transmissive film 3 can produce the second deformation 30 having the bending grid 31 by the extrusion of the first deformation 20 and the optical film 11.
In a specific embodiment, the backlight module 1 may further include a diffusion plate 12, a light emitting diode (LED 13), a reflective sheet 14, a back plate 15, and other structural members; the specific structure and function of these structural members are the same as or similar to those of related structural members of the prior art, and reference is specifically made to the prior art, and will not be repeated here.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a flexible light-transmitting film in a display panel according to a second embodiment of the present disclosure; the structure of the display panel provided in the second embodiment of the present application is substantially the same as that provided in the first embodiment of the present application, except that in the second embodiment of the present application, the flexible light-transmitting film 3 may further include only the elastic base 34 and the grill 31; and the grille 31 is disposed within the elastic matrix 34. Specifically, the elastic substrate 34 may be a solid substrate, so as to provide the flexible light-transmitting film 3 with necessary mechanical properties as a film layer body; so that the flexible light-transmitting film 3 has certain stiffness and flexibility at the same time, and the flexible light-transmitting film 3 can deform under the extrusion of external force and recover the deformation after the external force is removed. The grids 31 are disposed in the elastic matrix 34 at equal intervals along the first direction X, and each of the grids 31 is completely covered by the elastic matrix 34. Specifically, the material of the elastic substrate 34 may be a light-transmitting gel having elasticity so as to avoid affecting the light transmittance of the flexible light-transmitting film 3.
