It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the description of the present application, it should be understood that the terms "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application.

The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not in themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.
Referring to fig. 1 to 2, an embodiment of the present application provides a display module, including: the backlight 10, the lower polarizer 92, the liquid crystal layer 8, the upper polarizer 72, and the cover plate 1 are sequentially stacked. The cover plate 1 is provided with a display area and a non-display area, and the non-display area is positioned at the periphery of the display area; the display module further comprises a polaroid 2 and a black shading layer 3, wherein the polaroid 2 is arranged on one side of the cover plate 1 facing the upper polarized light and is positioned in the non-display area, and the black shading layer 3 is positioned on one side of the polaroid 2 away from the cover plate 1.
The backlight 10 is also referred to as a light source or a backlight 10, and may be, for example, an LED lamp panel. It will be appreciated that the liquid crystal molecules themselves cannot emit light, and thus if a picture is desired to appear, a dedicated light source is required to provide light, which is then deflected by the liquid crystal molecules to produce a different colour. The backlight 10 in the application also plays a role of a light source, so that the liquid crystal display module can display corresponding content. The black light-shielding layer 3 is mainly used for providing black, and the black which can be seen by human eyes is a black display effect after the polarizer 2 is acted.
Wherein, the upper polarizer 72 and the lower polarizer 92 are positioned at both sides of the liquid crystal layer 8 for controlling light passing through in a single direction. The liquid crystal layer 8 includes a driving circuit layer 81, a liquid crystal molecule layer 82, and a color film layer 83, which are laminated in this order, for example. The driving circuit layer 81 is used to control the deflection angle of the liquid crystal molecules in the liquid crystal molecule layer 82 under a driving signal. The color film layer 83 is used for generating light rays with different colors to realize a color display effect. Those skilled in the art can select an appropriate upper polarizer 72, lower polarizer 92, and liquid crystal layer 8 as needed, which are not essential improvements of the present application, and will not be further described herein.
The cover plate 1 is a transparent glass cover plate 1 and is used for protecting the display module. In the prior art, a black ink layer is generally provided on the cover plate 1, and the black ink layer is used to define a display area. However, after the glass cover plate 1 is attached to the display screen, the visual area shows the black effect of the display screen, but the black color of the ink has larger chromatic aberration with the black effect of the screen, so that the panel of the whole product can see two different black colors, and the visual effect of the product can be reduced when the screen is extinguished.
In the application, the polaroid 2 is arranged in the non-display area of the cover plate 1, and the black shading layer 3 is arranged on one side, deviating from the cover plate 1, of the polaroid 2, and the black color seen by eyes in the display area and the non-display area is the black color effect which is presented after the effect of the polaroid 2, so that the black color effect presented in the display area of the cover plate 1 and the black color effect presented in the non-display area are relatively close when the screen is extinguished, and the integral black display effect of the display module is improved.
In some embodiments of the present application, the black light shielding layer 3 includes at least one of a black adhesive layer, a black resin layer, and a black ink layer.
Illustratively, the black light shielding layer 3 includes a black adhesive tape layer, that is, is formed by adhering a black adhesive tape to the polarizer 2, and the manufacturing process is simple, which is advantageous in reducing manufacturing costs. Specifically, the black tape may be black mylar, which is not limited herein. In other embodiments of the present application, the black light-shielding layer 3 may be formed by using black ink in the prior art, or may be other black paint or black resin layer, which is not limited herein.
In some embodiments of the present application, the thickness of the black light shielding layer 3 is between 0.05mm and 0.15 mm. It will be appreciated that if the thickness of the black light-shielding layer 3 is too small, for example, the thickness of the black light-shielding layer 3 is less than 0.05mm, a higher process accuracy is required, resulting in higher manufacturing costs. If the thickness of the black light-shielding layer 3 is too large, for example, the thickness of the black light-shielding layer 3 is greater than 0.15mm, an increase in material cost is liable to result.
In some embodiments of the present application, the thickness of the polarizer 2 is between 0.05mm and 0.25 mm. It is understood that if the thickness of the polarizer 2 is too small, for example, the thickness of the polarizer 2 is less than 0.05mm, the manufacturing cost of the polarizer 2 is high, which is not beneficial to improving the "integral black" display effect of the display module. If the thickness of the polarizer 2 is too large, for example, the thickness of the polarizer 2 is greater than 0.25mm, an increase in material cost is easily caused, and an increase in thickness of the display module is easily caused.
In some embodiments of the present application, the light transmittance of the polarizer 2, the lower polarizer 92, and the upper polarizer 72 is the same, and this structure is advantageous for improving the "integral black" display effect of the display module. Illustratively, the polarizer 2, the lower polarizer 92, and the upper polarizer 72 may be prepared and formed of the same material.
In some embodiments of the present application, the display module further includes a touch layer 5, where the touch layer 5 is disposed on a side of the upper polarizer 72 facing away from the liquid crystal layer 8. Specifically, the touch layer 5 is a transparent layer. It should be noted that, the touch layer 5 is used for implementing touch operation control on the display module. Those skilled in the art can select an appropriate touch layer 5 as required, which is not a major improvement of the present application and will not be further described herein.
In some embodiments of the present application, the display module further includes a first adhesive layer 4, where the first adhesive layer 4 is disposed between the touch layer 5 and the upper polarizer 72. Specifically, the first adhesive layer 4 is an optical adhesive layer, and is used for fixing the touch layer 5.
In some embodiments of the present application, the display module further includes a second adhesive layer 6, where the second adhesive layer 6 is disposed between the touch layer 5 and the cover plate 1. Specifically, the second adhesive layer 6 is an optical adhesive layer, and is used for fixing the cover plate 1.
In some embodiments of the present application, the first adhesive layer 4, the touch layer 5, the second adhesive layer 6 and the cover plate 1 are all transparent layers, and the total light transmittance of the first adhesive layer 4, the touch layer 5, the second adhesive layer 6 and the cover plate 1 is greater than or equal to 80%. It can be appreciated that, because the first adhesive layer 4, the touch layer 5, the second adhesive layer 6 and the cover plate 1 are transparent, the polarizer 2 is arranged on one side of the black shading layer 3 close to the cover plate 1, the upper polarizer 72 is arranged on one side of the liquid crystal layer 8 close to the cover plate 1, and the upper polarizer 72 and the polarizer 2 are made of the same or similar materials, so that the color of the black shading layer 3 and the liquid crystal layer 8 can be greatly weakened for the eyes of people to see, and the integral black display effect of the display module can be further improved when the display screen is not lightened.
The present application further provides a display device (not shown in the drawings), where the display device includes the backlight module described above. The display device has the backlight module, so that the display device has the same beneficial effects, and the utility model is not repeated here.
The application of the display device in the embodiments of the present application is not particularly limited, and the display device may be any product or component with a display function, such as a television, a notebook computer, a tablet computer, a wearable display device (e.g., a smart bracelet, a smart watch, etc.), a mobile phone, a virtual reality device, an augmented reality device, a vehicle-mounted display, an advertisement lamp box, etc. In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to related descriptions of other embodiments.
The display module and the display device provided by the embodiments of the present application are described in detail, and specific examples are applied to illustrate the principles and the implementation of the present application, and the description of the above embodiments is only used to help understand the technical solution and the core idea of the present application; those of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
