The same reference numerals in the drawings denote the same or similar structures, and thus their repetitive description will be omitted. The words used in this application to describe positions and orientations are provided by way of example in the drawings and can be changed as desired and are intended to be encompassed by the present application. The drawings of the present application are for illustrating relative positional relationships only and do not represent true scale.
It should be noted that in the following description, specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import to those skilled in the art without departing from the spirit and scope of this application. The present application is therefore not limited to the specific embodiments disclosed below. The following description is of the preferred embodiment for carrying out the present application, but is made for the purpose of illustrating the general principles of the application and is not to be taken in a limiting sense. The protection scope of the present application shall be subject to the definitions of the appended claims.
The following describes a liquid crystal display and a display device provided in embodiments of the present application with reference to the accompanying drawings.
An embodiment of the present application provides a liquid crystal display, as shown in fig. 1 and fig. 2, including: the liquid crystal display device comprises a liquid crystal display panel 10, a backlight module 20 arranged on one side of the liquid crystal display panel 10, a camera 30, a first polarizer 11 positioned on one side of the liquid crystal display panel 10 departing from the backlight module 20, and a second polarizer 12 positioned on one side of the liquid crystal display panel 10 facing the backlight module 20;
the backlight module 20 includes a first backlight area B1 and a second backlight area B2, the camera 30 is located in the second backlight area B2, as shown in fig. 3, a side light source structure 40 surrounding the camera 30 is disposed on a side surface of the camera 30, and the side light source structure 40 is used for emitting light to the liquid crystal display panel 10;
as shown in fig. 1, the first polarizer 11 has a hollowed-out region S1 in a region corresponding to the second backlight region B2; alternatively, as shown in fig. 2, second polarizer 12 has a hollowed-out area S1 in an area corresponding to camera 30;
the liquid crystal display further includes an electroluminescent polarization structure 50 located in the hollow area S1, the electroluminescent polarization structure 50 is configured to be in a polarization state when powered on and in a transparent state when powered off.
It can be understood that when the electroluminescent polarization structure is located in the hollow area of the first polarizer, when the electroluminescent polarization structure is powered on, the polarization angle of the electroluminescent polarization structure is perpendicular to the polarization angle of the second polarizer, so that the electroluminescent polarization structure and the first polarizer have the same function, and normal display is realized; when the electroluminescent polarizing structure is positioned in the hollow area of the second polarizer, the polarizing angle of the electroluminescent polarizing structure is vertical to that of the first polarizer when the electroluminescent polarizing structure is electrified, so that the electroluminescent polarizing structure has the same action with the second polarizer, and normal display is realized.
In the liquid crystal display provided by the embodiment of the application, because the side-in light source structure is positioned on the side surface of the camera, the camera is prevented from being shielded. When the camera is started, the side-entry light source structure is closed, the electroluminescent polarizing structure is not electrified, and the electroluminescent polarizing structure is in a transparent state; when the camera is closed, the electroluminescent polarization structure is electrified and is in a polarization state, the lateral light source structure is opened, and emergent light rays of the lateral light source structure irradiate the liquid crystal display panel, so that normal display is realized.

When the electroluminescent polarization structure is disposed on the first polarizer side, since the thickness of the electroluminescent polarization structure is generally greater than that of the first polarizer, the flatness of the light-emitting side of the liquid crystal display panel may be affected.
Therefore, optionally, in the liquid crystal display provided in the embodiment of the present application, the second polarizer has a hollowed-out region in a region corresponding to the camera, so that the electroluminescent polarization structure may be disposed on the second polarizer side.
Further, in the liquid crystal display provided in the embodiments of the present application, the electroluminescence polarization structure is disposed on a side of the camera facing the liquid crystal display panel. Namely, the electroluminescent polarizing structure is formed on the camera, so that the alignment precision of the electroluminescent polarizing structure and the camera can be ensured. In the implementation, the electroluminescent polarization structure may be attached to the liquid crystal display panel, and is not limited herein.
In specific implementation, in the liquid crystal display provided in the embodiments of the present application, as shown in fig. 4 and fig. 5, fig. 5 is a schematic cross-sectional structure along the AA' direction of the structure shown in fig. 4; the lateral light source structure 40 includes a light source 41 and a light guide layer 42 located between the light source 41 and the camera 30;
the light guide layer 42 is used to guide light emitted from the light emitting source to the liquid crystal display panel 10.
In specific implementation, the light guide layer may be formed by using an existing light guide plate, the light guide plate may be made of high-transmittance materials such as polymethyl methacrylate (PMMA) or Polycarbonate (PC), or the light guide layer may be formed by using a micro-structured light guide film, the micro-structured light guide film is generally made of a resin material, and the micro-structured light guide film has the characteristics of high light transmittance, thin film layer and the like.
Further, in the present application, as shown in fig. 6, the light emitting source 41 and the light guiding layer 42 may be fixed to the side of the camera 30 by using a black flexible adhesive tape 60, so as to prevent the light from leaking from the light emitting source 41.
Alternatively, in the liquid crystal display provided in the embodiment of the present application, as shown in fig. 6, the light guide layer 42 is provided with a groove on a side facing the light emitting source 41. The grooves may collect light emitted from the light emitting sources 41, thereby improving backlight brightness of the second backlight area.
In a specific implementation, in the liquid crystal display provided in the embodiments of the present application, the light source may include an LED light source, and may also be other light sources, which is not limited herein.
Further, in the present application, as shown in fig. 7, the LED light source may include a plurality of white Mini LEDs 410, and the plurality of white Mini LEDs 410 are disposed around the camera 30, so that the structure of the side-in light source structure 40 may be simplified.
Alternatively, as shown in fig. 8, in the liquid crystal display provided in the embodiment of the present application, the LED light source may include: a plurality of red (R) Mini LEDs 411, a plurality of green (G) Mini LEDs 412, and a plurality of blue (B) Mini LEDs 413; a plurality of R Mini LEDs 411 are disposed around the camera 30, a plurality of G Mini LEDs 412 are disposed around the camera 30, and a plurality of B Mini LEDs 413 are disposed around the camera 30; and the plurality of R Mini LEDs 411, the plurality of G Mini LEDs 412, and the plurality of B Mini LEDs 413 are arranged in the thickness direction of the camera 30.
In specific implementation, the arrangement order of the R Mini LED, the G Mini LED and the B Mini LED in the LED light source is not limited, for example, along the thickness direction of the camera, the arrangement order may be any one of RGB, RBG, GRB, GBR, BRG or BGR.
Optionally, in order to improve the transmittance of the region corresponding to the camera to improve the image capturing effect, as shown in fig. 9, in the liquid crystal display provided in the embodiment of the application, a color film layer 101 is disposed in the liquid crystal display panel 10, and the region of the color film layer 101 corresponding to the second backlight area B2 is a hollow region. That is, the color film layer 101 in the area corresponding to the first backlight area is removed, so that the transmittance of the second backlight area B2 can be improved.
In addition, although the area of the color film layer corresponding to the first backlight area is removed in the present application, since the LED light source includes the R Mini LED, the G Mini LED, and the B Mini LED, color display can be arbitrarily realized by time-sharing driving the side-entry light source structure, that is, sequentially turning on the R Mini LED, the G Mini LED, or the B Mini LED in the LED light source during normal display.
