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.
Fig. 1 is a schematic cross-sectional view of a flexible backlight module according to an embodiment of the disclosure. The flexible backlight module can be applied to flexible display devices, and the flexible display devices comprise but are not limited to electronic equipment such as mobile phones, tablet computers and wearable equipment.
As shown in fig. 1, the flexible backlight module may include:
light sources 1 of n colors;
the light source 1 is arranged at the edge of the flexible light guide plate 2, and a plurality of groups of reflecting units 3 are arranged in the flexible light guide plate 2;
wherein each group of the reflection units 3 includes n reflection units 3, the n reflection units 3 are configured to reflect n color light beams emitted by the n color light sources 1, and an ith reflection unit 3 of the n reflection units 3 is configured to reflect light beams emitted by an ith color light source of the n color light sources without reflecting light beams emitted by other color light sources, for example, different coatings may be formed on reflection surfaces of the reflection units that reflect different color light beams, and the different coatings may reflect light beams with different wavelengths, so that different reflection units may reflect light beams with different colors, and further light beams emitted by the ith color light source 1 are perpendicular (may not be strictly perpendicular, for example, an emission angle may not be limited to 90 °, and may be 80 ° to 100 °) to the light exit surface of the flexible light guide plate 2, and light rays emitted by the light sources with other colors are not emitted from the position, corresponding to the ith reflection unit, of the flexible light guide plate, and i is more than or equal to 1 and less than or equal to n.
For convenience of explanation of the present embodiment, fig. 1 shows only light sources of two colors, a light source 1A and a light source 1B, and a reflection unit for reflecting light rays of two colors, a reflection unit 3A and a reflection unit 3B. Actually, light sources of more colors and reflection units for reflecting more colors may be provided as needed, and the positional relationship between the light sources of different colors is not limited to that shown in fig. 1, and may be provided along the thickness direction of the flexible light guide plate 2, or may be provided along the length direction of the flexible light guide plate 2 as needed.
In one embodiment, as shown in fig. 1, n color light sources 1 may be disposed on one edge of the flexible light guide plate 2, and light emitted from the light sources 1 may be incident into the flexible light guide plate 2.
In addition to the reflection unit 3, a plurality of dots may be disposed in the flexible light guide plate 2, for example, on the light exit surface and the surface opposite to the light exit surface of the flexible light guide plate 2. The dots may reflect light for guiding the light emitted from the light source 1 to an area far from the light source in the light guide plate so as to irradiate the reflection unit 1 located at the area far from the light source.
The reflection unit 3 may be disposed on a surface of the flexible light guide plate 2 opposite to the light exit surface, and the reflection unit 3 may emit the light emitted from the light source 1 perpendicular to the light exit surface of the flexible light guide plate 2.
Accordingly, the reflection unit can be arranged at a required position, for example, when the flexible backlight module is applied to a flexible display device, the reflection unit and the sub-pixels of the flexible display device can be arranged correspondingly, so that the reflection unit can reflect light of a specific color into the specific sub-pixels, for example, red light is reflected into the red sub-pixels, green light is reflected into the green sub-pixels, blue light is reflected into the blue sub-pixels, light of different colors is emitted from different positions of the light guide plate through the reflection unit, sub-pixels of different colors are emitted, and light of other colors is emitted from the flexible display device at the position of the sub-pixel, thereby ensuring that light of other colors cannot be emitted at the position of the sub-pixel.
The reflection unit arranged in the flexible backlight module plays a role in selecting colors of light equivalent to that of the color film substrate. Therefore, when the flexible backlight module described in this embodiment is applied to a flexible display device (or a non-flexible display device), a color film substrate does not need to be arranged in the flexible display device, so that the thickness of the flexible display device can be effectively reduced, and the flexible display device is convenient to carry and bend.
As shown in fig. 1, the reflection unit 3A may reflect the light emitted from the light source 1A, so that the light emitted from the light source 1A is emitted perpendicularly from the light-emitting surface of the flexible light guide plate, and the reflection unit 3B may reflect the light emitted from the light source 1B, so that the light emitted from the light source 1B is emitted perpendicularly from the light-emitting surface of the flexible light guide plate, so as for the reflection unit 3A, the light emitted from the light source 1B may not be irradiated on the reflection unit 3A in the flexible light guide plate, or the reflection unit 3A may only reflect the light emitted from the light source 1A, but not reflect the light emitted from the light source 1B, so that the light emitted from the light source 2 is not emitted from the position of the flexible light guide plate corresponding to the i-th reflection unit.
For example, the light source 1A is a red light source, and the light source 1B is a green light source, when the flexible backlight module is applied to a flexible display device, the reflection unit 3A may be disposed corresponding to the red sub-pixel, and the reflection unit 3B may be disposed corresponding to the green sub-pixel.
Therefore, the reflection unit 3A can reflect the red light emitted from the light source 1A, and emit the red light perpendicularly to the light emitting surface of the flexible light guide plate 2, and further emit the red light into the red sub-pixel, and the red light can be controlled to emit from the position of the red sub-pixel by controlling the switch of the red sub-pixel, and because the reflection unit 3A only reflects the red light, that is, does not reflect the light of other colors, only the red light can be emitted from the position of the red sub-pixel.
Similarly, the reflection unit 3B can reflect the green light emitted from the light source 1B, and emit the green light perpendicularly to the light emitting surface of the flexible light guide plate 2, and further emit the green light into the green sub-pixel, and the green light can be controlled to emit from the position of the green sub-pixel by controlling the switch of the green sub-pixel, and since the reflection unit 3B only reflects the green light, that is, does not reflect the light of other colors, only the green light can be emitted from the position of the green sub-pixel.
Therefore, the reflection unit 3 is arranged in the flexible light guide plate, so that light rays of each color can be emitted from the position corresponding to the color sub-pixel, a color film substrate does not need to be arranged for filtering the light rays emitted by the sub-pixels, and the thickness of the flexible display device can be effectively reduced.
It should be noted that, because the propagation angles of the light beams emitted into the flexible light guide plate by the light sources with different colors may be different, the structures of the reflection units at different positions may be different, for example, the included angle between the reflection surface of the reflection unit and the light exit surface of the flexible light guide plate may be different, as shown in fig. 1, the included angle between the reflection surface of the reflection unit 3A and the light exit surface of the flexible light guide plate is larger than the included angle between the reflection surface of the reflection unit 3B and the light exit surface of the flexible light guide plate.
Of course, for the reflection units at different positions, the relationship between the included angles between the reflection surface and the light exit surface of the flexible light guide plate is not limited to the case shown in fig. 1, and the relationship may be set according to the position of the specific light source and the propagation path of the light emitted into the flexible light guide plate by the light source in the flexible light guide plate.
Optionally, the reflecting surface of the reflecting unit is a curved surface.
In one embodiment, the reflecting surface of the reflecting unit is not limited to a plane, and may be provided as a curved surface, for example, a concave surface, as needed.
Because the angle of the light irradiating on the reflection unit can be different, the reflection surface is a curved surface, so that the reflection surface at different positions on the reflection unit can reflect the incident light with different incident angles at different reflection angles, and the light after reflection can be ensured to be vertical to the emergent surface of the flexible light guide plate to be emitted out of the flexible light guide plate.
Optionally, the ith reflection unit transmits light emitted from the light source of the ith color among the light sources of the n colors.
In one embodiment, the ith reflecting unit may be configured to reflect only light emitted by the light source of the ith color, and transmit light emitted by the light sources of other colors, so as to ensure that light emitted by the light sources of other colors is not reflected or absorbed by the ith reflecting unit, so that the reflecting unit for reflecting light of the corresponding color in the flexible light guide plate can receive and reflect light of the color.
For example, the reflection unit for reflecting red light may be configured to reflect red light, and transmit light emitted by other color light sources of the green light and the blue light, so as to ensure that light emitted from the position of the reflection unit corresponding to the flexible light guide plate for reflecting red light is all red light, which is beneficial to avoiding color cast at the position, and for green light, it is beneficial to the reflection unit for reflecting green light in the flexible light guide plate to receive green light and reflect green light.
Optionally, the ith light source emits light, and the light irradiates the ith reflection unit in the flexible light guide plate.
In one embodiment, it is ensured that the ith light source emits light by designing a propagation light path of the light emitted by the ith light source in the flexible light guide plate, and the light emitted by the light sources of other colors is irradiated on the ith reflection unit in the flexible light guide plate, so that the light emitted by the light sources of other colors is not reflected by the ith reflection unit and is emitted at a position of the flexible light guide plate corresponding to the ith reflection unit.
For example, for a light source emitting red light, the light path of the light emitted by the light source emitting red light may be designed so that the red light emitted by the light source emits on the reflection unit reflecting red light in the flexible light guide plate, and the light emitted by the light sources of other colors does not illuminate on the reflection unit reflecting red light, so that the light emitted from the position of the reflection unit reflecting red light corresponding to the flexible light guide plate is all red light, which is beneficial to avoiding color cast at the position.
Fig. 2 is a schematic cross-sectional view of another flexible backlight module according to an embodiment of the disclosure. As shown in fig. 2, the flexible backlight module further includes:
the light condensing structure is arranged on the light emergent side of the flexible light guide plate;
the light condensing structure comprises a plurality of light condensing units 4, wherein the light condensing units 4 are arranged in one-to-one correspondence with the reflecting units 3 and are used for condensing the light rays reflected out of the flexible light guide plate 2 by the reflecting units 3.
In one embodiment, the light condensing units may be convex lenses, for example, convex lenses made of transparent flexible materials, and specific curvatures of the convex lenses may be set as required, and the light condensing effect of the light condensing units located at different positions may be different, for example, the curvatures of the convex lenses at different positions are different.
Since the reflecting unit 3 needs to reflect light through the reflecting surface, which may be difficult to ensure that all reflected light rays are emitted due to process limitations, the exit angle from the flexible light guide plate is the same, but there is likely to be some degree of divergence.
Through setting up the spotlight structure, spotlight unit and the reflection element one-to-one in the spotlight structure sets up, for example spotlight unit's projection and reflection element coincidence in flexible light guide plate can make through reflection element reflection and the light of emiting flexible light guide plate, before the sub-pixel of corresponding colour of emittings, can be assembled by spotlight unit earlier to avoid inciting into the sub-pixel of other colours and cause the colour cast, and can ensure the luminance of the sub-pixel of corresponding colour.
Optionally, among the n color light sources, at least one color light source is disposed at a different edge of the flexible light guide plate from the other color light sources.
In one embodiment, since the light emitted from the light source into the flexible light guide plate is directed to the reflection unit from the direction of the light source, whether or not reflected by the dots inside the flexible light guide plate, in order to reflect the light emitted from the light source by the reflection unit, the reflection surface of the reflection unit needs to be directed to the light source, for example, as shown in fig. 1, the reflection surface of the reflection unit 3A is directed to the light source 1A, and the reflection surface of the reflection unit 3B is directed to the light source 1B.
The light emitted by the light source of the ith color is reflected by the ith reflection unit, which means that the median of the wave band of the light reflected by the ith reflection unit is close to or coincident with the median of the wave band of the light emitted by the light source of the ith color, but the wave band of the light reflected by the ith reflection unit is more or less different from the wave band of the light emitted by the light source of the ith color, that is, the light of other colors except the ith color is more or less reflected by the ith reflection unit.
Fig. 3 is a schematic plan view illustrating a flexible backlight module according to an embodiment of the present disclosure.
The present embodiment arranges at least one color light source and other color light sources at different edges of the flexible light guide plate, for example, as shown in fig. 3, the light source 1A is disposed at the lower side edge of the flexible light guide plate 2, and the light source 1B is disposed at the left side edge of the flexible light guide plate 2, then the reflective surface of the reflective unit corresponding to the light source may be disposed toward the light source, that is, the reflective surface of the reflective unit 3A (not shown in fig. 3) shown in fig. 1 is disposed toward the lower side edge of the flexible light guide plate 2, the reflective surface of the reflective unit 3B (not shown in fig. 3) is disposed toward the left side edge of the flexible light guide plate 2, therefore, the light from the light source 1A is greatly reduced from being irradiated on the reflection unit 3B, and the light from the light source 1B is greatly reduced from being irradiated on the reflection unit 3A, which is beneficial to preventing the reflection unit from reflecting light with different colors, so that color cast is caused after the light is irradiated into the sub-pixel.
It should be noted that, based on the difference of n in the n color light sources, the edge of the flexible light guide plate where the light source is located may also be different, for example, for 3 color light sources, the light sources may be disposed on 3 edges of the flexible light guide plate.
Optionally, n-3.
In one embodiment, 3 color light sources may be provided, and each group of the reflection units may include 3 reflection units, where each group of the reflection units may correspond to a pixel unit in a flexible array substrate of the flexible display device, the pixel unit may include 3 color sub-pixels, and light reflected by each reflection unit is emitted from the flexible backlight module and enters the corresponding color sub-pixel.
Optionally, the 3-color light sources include a red light source, a green light source, and a blue light source. The pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.
Optionally, the 3 color light sources include a cyan light source, a magenta light source, and a yellow light source. The pixel cell may include a cyan sub-pixel, a magenta sub-pixel, and a yellow sub-pixel.
An embodiment of the present disclosure further provides a flexible display device, including the flexible backlight module according to any of the above embodiments, further including:
the flexible array substrate is arranged on the light emergent side of the flexible backlight module and comprises n color sub-pixels;
the area of the ith reflection unit in the flexible backlight module is positioned in the projection of the ith color sub-pixel in the n color sub-pixels to the flexible backlight module;
and the flexible liquid crystal layer is arranged on one side of the flexible array substrate, which is far away from the flexible backlight module.
In an embodiment, the flexible backlight module according to any of the above embodiments may be applied to a flexible display device, and in this case, the reflection unit may be disposed corresponding to a sub-pixel of the flexible display device, and specifically, an area where the ith reflection unit is located in the flexible backlight module may be disposed in a projection of the ith sub-pixel of the n sub-pixels to the flexible backlight module, so that the reflection unit may reflect light of a specific color to a specific sub-pixel, for example, reflect red light to a red sub-pixel, reflect green light to a green sub-pixel, and reflect blue light to a blue sub-pixel.
Therefore, light with different colors is emitted from different positions of the light guide plate through the reflection unit, then enters the sub-pixels with different colors, and is emitted from the flexible display device from the positions of the sub-pixels, light rays with other colors cannot be emitted from the positions of the sub-pixels, and the effect of selecting the color of the light equivalent to that of the color film substrate is achieved. Therefore, a color film substrate does not need to be arranged in the flexible display device, the thickness of the flexible display device can be effectively reduced, and the flexible display device is convenient to carry and bend.
Optionally, the flexible display device further comprises:
and the flexible cover plate is arranged on one side of the flexible liquid crystal layer, which is far away from the flexible array substrate.
In one embodiment, a flexible cover sheet may also be disposed on the flexible liquid crystal layer to protect the flexible liquid crystal layer and the flexible array substrate below the liquid crystal layer.
It should be noted that the flexible display device may further include other structures, such as a common electrode, an alignment layer, a polarizer, a touch panel, and the like, and these structures may also be flexible, so as to ensure that the flexible display device is flexible as a whole.
Fig. 4 is a schematic flow chart diagram illustrating a display control method according to an embodiment of the present disclosure. The display control method is applied to the flexible display device according to any one of the above embodiments, and as shown in fig. 4, the display method may include the following steps:
in step S1, controlling the n-colored light sources to turn on one by color, and controlling the n-colored sub-pixels to turn on one by color;
and when the light source of the i color is started, the sub-pixel of the ith color is started.
In one embodiment, the n color light sources may be controlled to be turned on one by one according to color during the process of displaying one frame of image, so that the light of each color may enter the flexible light guide plate and be reflected into the flexible array substrate by the reflection unit in the flexible guide tube plate, and in order to control the light to be emitted from the flexible liquid crystal layer, the n color sub-pixels may be controlled to be turned on one by one according to color, specifically, the light sources of the same color may be controlled to be turned on simultaneously, the sub-pixels of the same color are turned on simultaneously, and the sub-pixel of the ith color is turned on when the light source of the i color is turned on.
Therefore, when light of the ith color enters the flexible array substrate from the flexible light guide plate, the sub-pixels of the ith color are turned on, so that liquid crystals corresponding to the sub-pixels are deflected, the light of the ith color is emitted from the liquid crystal layer, light emitted by the light source can be smoothly emitted, and a good display effect is achieved.
