Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 1 to 3, the present embodiment provides a display module. It includes: a display panel 1 and a first film layer 2. The display panel 1 comprises a plurality of sub-pixel areas; the first film layer 2 is arranged corresponding to the display panel 1; the first film layer 2 is divided into a plurality of light transmission areas and reflection areas; the light-transmitting area corresponds to the sub-pixel area; the reflection area is used for reflecting the ambient light so that the display module can realize specular reflection.
The display panel 1 may be a liquid crystal display panel 1, an OLED (organic light-emitting diode) display panel 1, or other display panels 1, which is not limited in this embodiment.
In the display module provided in this embodiment, the display panel 1 is used for displaying; the light-transmitting regions of the first film layer 2 correspond to the sub-pixel regions of the display panel 1, so that light of each sub-pixel region of the display panel 1 can enter the user's field of vision through the light-transmitting regions. Meanwhile, the reflective region of the first film layer 2 is capable of specularly reflecting ambient light. In summary, in the display module provided in this embodiment, based on the light-transmitting area and the reflection area of the first film layer 2, the user can see both the display image of the display panel and the specular reflection image of the real environment, that is, the display module can combine the display image and the specular reflection image to display the display image to the user, thereby realizing the integration of the display image and the display environment.
In the prior art, the pixels of the display panel are usually arranged in an array, so the present embodiment is described by taking the example that the plurality of sub-pixel regions are arranged in an array. As shown in fig. 1, a plurality of sub-pixel regions are arranged in an array; the plurality of light-transmitting areas are arranged in an array; the light-transmitting areas correspond to the sub-pixel areas one by one; or, each of the plurality of light-transmitting areas corresponds to one sub-pixel area.
That is to say, in the corresponding relationship between the transparent regions and the sub-pixel regions in this embodiment, each sub-pixel region has at least one transparent region corresponding to it, so that the light of each pixel region of the display panel 1 can enter the user's view field, thereby ensuring that the display module can normally display the display image of the display panel 1, and avoiding the incomplete or distorted display image seen by the user. Specifically, the transparent region may correspond to the sub-pixel region in a manner that one transparent region or a plurality of transparent regions correspond to one sub-pixel region. Furthermore, in order to better display the display screen of the display panel 1 and the reflection screen of the first film material to the user in a fused manner, it is preferable to adopt a corresponding manner in which each of the plurality of light-transmitting regions corresponds to one of the sub-pixel regions.
It should be noted that, in order to realize the above display image and the specular reflection image, each light-transmitting area of the first film layer 2 should be relatively small in size to achieve a macroscopic invisible degree, at this time, the whole first film layer 2 can be regarded as a whole film layer, and the reflection area is used for reflecting ambient light, so that the real environment image can be displayed in a specular manner on the display surface side facing the display module; in the microcosmic aspect, each light-transmitting area can allow light to pass through, so that light of the backlight source can pass through the light-transmitting areas and irradiate the display module to provide backlight for the display module to display images, or light emitted by the self-luminous display module can directly pass through the light-transmitting areas and enter human eyes, and the human eyes can see the display images of the display module.
In this embodiment, in order to blend the reflective screen and the display screen well, the transparent region and the reflective region of the first film layer 2 are preferably uniformly distributed. Meanwhile, in the embodiment, the final display effect of the display module is determined by the setting ratio of the transparent region and the reflective region of the first film layer 2. In practical applications, a technician may specifically adjust the settings of the light-transmitting area and the reflecting area of the first film layer 2 according to user requirements or actual situation requirements, which is not limited in this embodiment.
It is understood that, based on the above-mentioned correspondence relationship between the light-transmitting regions and the sub-pixel regions, the size of the light-transmitting regions should be smaller than that of the sub-pixel regions. Since the size of the sub-pixel is usually on the micrometer scale, the size of the transparent region in this embodiment should be at least on the micrometer scale or even on the nanometer scale. Of course, as the resolution of the display panel 1 increases, the size of the sub-pixel region may be smaller, and the size of the light-transmitting region should be reduced accordingly.
In the display panel 1 of the prior art, the sub-pixel regions are usually arranged in an array, and therefore the light-transmitting regions are also preferably arranged in an array. For example, the first film 2 may be a film having a grid pattern, the grid regions arranged in an array are light-transmitting regions, and the other regions are reflecting regions.
Preferably, in this embodiment, the first film layer 2 is a patterned film layer, the hollow portion 21 of the first film layer 2 defines a light-transmitting region, and the main portion of the first film layer 2 defines a reflecting region.
As shown in fig. 1, the first film 2 is a patterned film having a main portion and a hollow portion 21. The light-transmitting area of the first film layer 2 can be defined by the hollow part 21, that is, the light-transmitting area of the first film layer 2 corresponds to the hollow area; the reflective area of the first film layer 2 is then defined by the main body portion. In this embodiment, the main body portion may be formed by using a reflective material, or a reflective film layer may be formed on the main body portion of the first film layer 2, so as to implement the function of specular reflection. Where it is to be understood that when forming the reflective film layer by forming it in the body portion of the first film layer 2, it should be formed at least on the display side of the body portion (i.e. the side closer to the user's eye). Specifically, the hollow portion 21 of the first film layer 2 in this embodiment can be realized by photolithography and other processes, and the difficulty of photolithography and other processes is different according to the size of the light-transmitting region.
Preferably, the material of the first film layer 2 may include a high-reflectivity metal. That is, the first film layer 2 in this embodiment may be a metal grid film. Specifically, the high-reflectivity metal may include aluminum, silver, and the like. The materials are adopted because the materials have high reflectivity to visible light, which can reach more than 95%, and can better meet the requirement of mirror reflection in the embodiment. Further, since silver has a higher reflectance, it is preferable to form the first film layer 2 using silver. Of course, it is understood that, because the cost of the silver material is high, aluminum or other materials may be used instead of silver, and the embodiment is not limited thereto.
Example 2:
as shown in fig. 1 and 2, the present embodiment provides a display module, which is substantially the same as the display module provided in embodiment 1. Particularly, the display module provided in the embodiment is particularly suitable for a liquid crystal display module and other display modules which need to be additionally provided with a backlight module.
As shown in fig. 2, the display module provided in this embodiment includes: the display panel 1 includes a light-transmissive display panel 1; the display module assembly still includes: a backlight module for providing a backlight source for the display panel 1; the first film layer 2 is disposed between the display panel 1 and the backlight module.
That is to say, in the display module provided in the present embodiment, the backlight module 5 mainly provides a backlight source for the display panel 1, so as to realize the display function of the display module. In the embodiment, the first film layer 2 is disposed between the display panel 1 and the backlight module. That is, the light emitted from the backlight module firstly passes through the light-transmitting region of the first film layer 2, and then passes through the light-transmitting region to enter the corresponding sub-pixel region of the display panel 1, so as to realize the display function.
Because the first film layer 2 is disposed between the display panel 1 and the backlight module, in order to implement the reflection function of the first film layer 2, the display panel 1 should have a light-transmitting state, so that external ambient light can pass through the display panel 1 and then be reflected by the first film layer 2, and the reflected ambient light can pass through the display panel 1 again and enter the user's view field to form a reflection picture.
The structure of the first membrane layer 2 in this embodiment is substantially the same as the structure of the first membrane layer 2 provided in embodiment 1. The first film layer 2 is preferably a patterned film layer having a main portion and a hollow portion 21, and the first film layer 2 is preferably a patterned film layer. The light-transmitting area of the first film layer 2 can be defined by the hollow portion 21, and the reflection area is defined by the main portion. Further preferably, in this embodiment, a surface of the reflection region of the first film layer 2, which is close to the display panel 1, includes an arc-shaped convex structure. That is, as shown in fig. 3, the first film layer 2 provided in this embodiment has an arc-shaped convex shape on the side close to the eyes of the user. The arc-shaped convex structure is used for enhancing the reflection capability of the first film layer 2 to the external environment light.
Specifically, as shown in fig. 2, when the first film layer 2 is a patterned film layer, the side surfaces of the main portion of the first film layer 2 (specifically, the side surfaces contacting with the hollow portions 21) may be processed to make the side surfaces of the main portion and the upper surface close to the display panel 1 form an arc-shaped structure together, that is, the cross-sectional shape of the main portion of the patterned first film layer 2 is a semicircular arc. Compared with the conventional structure with a rectangular or trapezoidal cross section (after the film layer is patterned, the cross section is rectangular in an ideal state, and is usually trapezoidal in practice) in the prior art, the main body part with the circular arc cross section in the embodiment has a larger reflection angle range to the ambient light, and the corresponding reflectivity is higher, so that the obtained mirror reflection picture is clearer.
Preferably, in this embodiment, the method further includes: and the anti-reflection film layer 3 is arranged between the first film layer 2 and the backlight module and is used for increasing the light transmittance of the first film layer 2, so that the light energy loss of the backlight module is reduced as much as possible, and the light energy utilization rate of the backlight module is improved. Meanwhile, the antireflection film layer 3 may serve as a protection layer of the first film layer 2 to protect a surface of the first film layer 2 close to the backlight module.
Preferably, in this embodiment, the method further includes: increase anti-rete 4, it sets up between first rete 2 and display panel 1 for increase first rete 2's reflection of light rate, thereby the reflection intensity of first rete 2 to external environment light of maximize improves the utilization ratio to external environment light. It is understood that the reflection-enhanced film layer 4 can also serve as a protection layer for the first film layer 2, and is used to protect the side of the first film layer 2 close to the display panel 1.
Example 3:
this embodiment provides a display module similar to the display modules provided in embodiments 1 and 2. Particularly, in the display module provided in this embodiment, the first film layer 2 is disposed on the display side of the display panel 1.
The display panel 1 may be a self-light emitting display panel such as the OLED display panel 1, or may be a non-self-light emitting display panel 1 such as the liquid crystal display panel 1.
In this embodiment, the first film layer 2 is disposed on the display surface side of the display panel 1, that is, when the display module provided in this embodiment displays, light (light emitted by the backlight module or light emitted by the display panel 1 breeding) emitted by each sub-pixel region enters human eyes through the light-transmitting region of the first film layer 2 to form a display image. Meanwhile, as shown in fig. 5, the reflective region of the first film layer 2 performs specular reflection on the external ambient light, so that a specular reflection picture can be formed in the eyes of a user. Therefore, when the display panel 1 displays, the user can simultaneously see the image formed by fusing the display image and the reflection image; when the display panel 1 is not displaying, as shown in fig. 4, the user can see the reflection screen as much as possible.
Of course, it is understood that the intensity ratio of the display frame to the reflective frame entering the human eye can be specifically adjusted according to the ratio of the transparent area to the reflective area of the first film layer 2, and the embodiment is not particularly limited.
Preferably, in this embodiment, a surface of the reflection region of the first film layer 2 facing away from the display side of the display panel 1 includes an arc-shaped protrusion structure.
I.e. the side of the reflective region of the first film layer 2 which is adjacent to the eye of the user comprises an arcuate raised structure.
Specifically, similar to embodiment 2, as shown in fig. 3, when the first film layer 2 is a patterned film layer, the side surfaces of the main body portion of the first film layer 2 (specifically, the side surfaces contacting with the hollow portion 21) may be processed to form an arc-shaped structure together with the upper surface facing away from the display panel 1, so as to enhance the reflection capability of the first film layer for ambient light.
Preferably, in this embodiment, the method further includes: and the anti-reflection film layer 3 is arranged on one side of the first film layer 2 close to the display panel 1 and is used for increasing the light transmittance of the first film layer 2, so that the light energy loss of the backlight module is reduced as much as possible, and the light energy utilization rate of the backlight module is improved. Meanwhile, the antireflection film layer 3 may serve as a protection layer for the first film layer 2 to protect the surface of the first film layer 2 close to the display panel 1.
Preferably, in this embodiment, the method further includes: increase anti-rete 4, it sets up in the one side that first rete 2 deviates from display panel 1 for increase first rete 2's reflection of light rate, thereby the reflection intensity of first rete 2 to external environment light of maximize improves the utilization ratio to external environment light. It is understood that the reflection-increasing film layer 4 can also be used as a protection layer of the first film layer 2 for protecting the side of the first film layer 2 away from the display panel 1.
