Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present application provide a display device, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. The display device 100 may include a display panel 10, a backlight module 20, a light guide module 30, a camera module 40, and a light emitting module 50.
The display panel 10 may include a lower polarizer 11, an array substrate 12, a color filter substrate 13, and an upper polarizer 14, which are sequentially stacked on the backlight module 20. It should be noted that the display panel 10 includes, but is not limited to, the above structure, and the display panel 10 may also include other structures. Such as liquid crystal layer, sealant, etc.
The array substrate 12 has a plurality of thin film transistors therein for controlling a display image of the display device 100. The color filter substrate 13 is a key component of the display device 100 for realizing colorization, and the display device 100 needs to provide hue through the RGB color resists in the color filter substrate 13 to form a color display image. The lower polarizer 11 is used to convert the light generated by the backlight module 20 into polarized light, and the upper polarizer 14 is used to analyze the polarized light after being electrically modulated by the liquid crystal to generate contrast, thereby generating a display picture.
The backlight module 20 may be disposed on one side of the display panel 10. The backlight assembly 20 may include an optical film 21, a light guide plate 22, and a reflective sheet 23 sequentially stacked on the display panel 10. The optical film 21 may include a prism sheet and a diffusion sheet sequentially stacked on the display panel 10.
Since the backlight source used in the conventional backlight module 20 is generally a Cold Cathode Fluorescent Lamp (CCFL) or a Light Emitting Diode (LED) Light bar, the cold cathode fluorescent Lamp is a linear Light source, and the LED Light bar is a point Light source, the Light guide plate 22 is required to convert the linear Light source and the point Light source into a surface Light source. The light guide plate 22 is a plate with smooth surface made of propylene by an injection molding method, then diffusion points are printed on the bottom surface of the light guide plate 22 by a screen printing method by using a material with high reflection and no light absorption, a cold cathode fluorescent lamp or a light emitting diode lamp strip is positioned at the side edge of the light guide plate 22, the emitted light is guided into the light guide plate 22 by reflection, when the light reaches the diffusion points, the reflected light is diffused to all angles, and then the reflection condition is destroyed to be emitted from the front surface of the light guide plate 22. The light guide plate 22 can emit light uniformly by using various diffusion dots with different densities and sizes.
The reflective sheet 23 serves to reflect light emitted toward the bottom surface back into the light guide plate 22, thereby improving the efficiency of light use. The light guide plate 22 and the reflective sheet 23 are used for guiding the light scattering and reflecting directions, so as to prevent the light from being emitted from the region other than the light emitting surface, improve the brightness of the backlight module 20, and ensure the brightness uniformity of the display panel 10.
The optical film 21, through cooperation of its multiple optical films, guides the light in the refraction, reflection and scattering directions by improving the angular distribution of the light without increasing the number of light sources, and homogenizes the light, concentrates the light on the front view angle, and increases the total luminous flux, thereby reducing the loss of the light sources and increasing the axial brightness of the display panel 10.
The backlight module 20 has an opening 24. The opening 24 may be a through hole penetrating the backlight module 20 or a blind hole penetrating the light guide plate 22 and the reflective sheet 23 of the backlight module 20. It should be noted that, when the opening 24 is a blind hole penetrating through the light guide plate 22 and the reflective sheet 23 of the backlight module 20, the material of the optical film 21 corresponding to the opening 24 may be a transparent material, such as Polyethylene terephthalate (PET). So as to increase the transmittance of the corresponding portion of the optical film 21 located in the opening 24 and avoid the optical film 21 from affecting the light transmission in the area of the opening 24. In particular, reference may be made to fig. 2.
The light guide module 30 can be inserted into the opening 24 of the backlight module 20. Referring to fig. 3 in conjunction with fig. 1 or fig. 2, the light guide module 30 may include a first component 31, a second component 32, and a third component 33. Wherein the first part 31 may be located within the aperture 24. The second member 32 and the third member 33 are positioned at a side of the first member 31 away from the backlight assembly 20. The first, second and third parts 31, 32, 33 may cooperate to form a recess 34.
It should be noted that the terms "first", "second" and "third" in the description of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the described features.
It should be noted that in the description of the embodiments of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.
Wherein the first member 31 may include a first side 311 and a second side 312. The first side 311 is opposite to the second side 322. The second part 32 may include a first side 321, a second side 322, and a third side 323. The first side 321 is connected to the second side 322 and the third side 323. The third part 33 may include a fourth side 331, a fifth side 332, and a sixth side 333. Wherein, the fourth side 331 is connected to the fifth side 332 and the sixth side 333, respectively.
In the embodiment of the present application, the first side 331 of the first member 31 may be connected to the first side 321 of the second member 32, and the first side 331 of the first member 31 may form an obtuse angle with the first side 321 of the second member 32. The second side 322 of the second section 32 is disposed parallel to the first side 311 of the first section 31. It will be appreciated that the third side 323 of the second member 32 coincides with the side of the first member 31 remote from the backlight assembly 20. The fourth side 331 of the third member 33 is connected to the second side 312 of the first member 31, and the angle between the fourth side 331 of the third member 33 and the second side 312 of the first member 31 is obtuse. The fifth edge 332 of the third member 33 is disposed parallel to the second side edge 312 of the first member 31. It will be appreciated that the sixth side 333 of the third member 33 coincides with the side of the first member 31 remote from the backlight assembly 20.
It should be noted that, in the embodiment of the present application, the surface of the light guide module 30 is a mirror structure. The first side 321 of the second member 32 and the fourth side 331 of the third member 33 are light incident surfaces of the light guide module 30.
Because the surface of the light guide module 30 provided in the embodiment of the present application is a mirror structure, when light enters from the first edge 321 of the second component 32 and the fourth edge 331 of the third component 33, the light can be refracted at the first edge 321 of the second component 32 and the fourth edge 331 of the third component 33, so that the light can be uniformly distributed in the area of the display panel 10 corresponding to the opening 24, so as to improve the brightness of the display panel 10 in the area of the opening 24, thereby improving the display effect of the display device 100.
The camera module 40 can be inserted into the groove 34 of the light guide module 30. The camera module 40 is a camera.
The light emitting module 50 is used for providing a light source for the light guide module 30. Since the first side 321 of the second member 32 and the fourth side 331 of the third member 33 are light incident surfaces, that is, the light emitting module 50 can provide a light source for the knife beam module 30 from the first side 321 of the second member 32 and the fourth side 331 of the third member 33. In the embodiment of the present application, a PIN may be disposed on the light emitting module 50, and connected to the main board of the display device 100 to individually supply power to the light emitting module 50 and control the light emission.
Referring to fig. 4, in some embodiments, in order to further improve the display effect of the display device 100, a first through hole 111 corresponding to the opening 24 may be disposed on the lower polarizer 11 of the display panel 10. And a second through hole 141 corresponding to the opening 24 is provided on the upper polarizer 14. At this time, since the lower polarizer 11 of the display device 100 is provided with the first through hole 111 corresponding to the opening 24 and the upper polarizer 14 is provided with the second through hole 141 corresponding to the opening 24, when the light in the area of the opening 24 needs to be emitted from the display panel 10, the loss of the light in the lower polarizer 11 and the upper polarizer 14 can be reduced, the utilization rate of the light can be improved, the brightness of the display panel 10 in the area of the opening 24 can be improved, and the display effect of the display device 100 can be improved.
It can be understood that, because the lower polarizer 11 of the display device 100 is provided with the first through hole 111 corresponding to the opening 24, and the upper polarizer 14 is provided with the second through hole 141 corresponding to the opening 24, when the camera module 40 needs to obtain the ambient light, the ambient light does not need to pass through the lower polarizer 11 and the upper polarizer 14, so that the consumption of the ambient light is reduced, the brightness of the ambient light collected by the camera module 40 is increased, and the shooting quality of the camera module 40 is further improved.
It can be understood that the size of the opening 24 of the backlight module 20 is very small, and therefore, the size of the light guide module 30 inserted into the opening 24 is smaller. The light guide module 30 is small in size, which causes inconvenience in assembling the light guide module 30 and the backlight module 20. In some embodiments, for the convenience of assembly, the light guide module 30 may be integrally formed with the light guide plate 22 of the backlight module 20, that is, the light guide plate 22 is an extension of the light guide module 30 extending toward the sidewall of the opening 24. This may be particularly shown in figure 5.
In view of the above, the display panel provided in the embodiment of the present application includes the display panel 10, the backlight module 20, the light guide module 30, the camera module 40, and the light emitting module 50. Wherein, the backlight module 20 is disposed at one side of the display panel 10, and the backlight module 20 is provided with an opening 24; the light guide module 30 is inserted into the opening 24, the light guide module 30 includes a first component 31, a second component 32 and a third component 33, the first component 31 is located in the opening 24, the second component 32 and the third component 33 are located on one side of the first component 31 away from the backlight module 20, and the first component 31, the second component 32 and the third component 33 cooperate to form a groove 34; the camera module 40 is inserted into the groove 34; the light emitting module 50 is used for providing a light source for the light guiding module 30. According to the present disclosure, the light guide module 30 is inserted into the opening 24 of the backlight module 20, so that the light source provided by the light emitting module 50 is uniformly distributed on the display panel 10 corresponding to the opening 24, thereby improving the brightness of the display panel 10 corresponding to the opening 24, and further improving the display effect of the display device 100.
