The invention provides a liquid crystal display device.
Referring to fig. 1, 2, 4 and 6, in an embodiment of the present invention, the liquid crystal display device includes:
the shell body 1 comprises a back plate 11, wherein two opposite side edges of the back plate 11 are respectively provided with a sliding chute 10 extending along the corresponding side edge, and the notches of the two sliding chutes 10 are oppositely arranged; an electric control accommodating space 14 which is partially extended outwards is formed on the inner side of the back plate 11;
the display module 2 comprises a support frame 21, a display screen 22 and an optical diaphragm group 23, wherein the display screen 22 and the optical diaphragm group 23 are arranged on the support frame 21; the frame strips 211 at two opposite sides of the supporting frame 21 are respectively slidably mounted in the two sliding slots 10, so that the display module 2 is mounted on the housing 1; and
and the electronic control module 6, wherein the electronic control module 6 is installed in the electronic control accommodating space 14.
Without loss of generality, in the present embodiment, the optical film set 23 includes a reflective sheet 232, a light guide plate 231, and other optical films (e.g., DOP film 233); the display screen 22 is typically an LCD screen. In this embodiment, the electronic control accommodating space 14 is preferably formed by partially arching the back plate 11 outward, the forming method is simple, and the production is easy, and it can be understood that the accommodating opening of the electronic control accommodating space 14 is located on the inner side surface of the back plate 11; however, the design is not limited to this, in other embodiments, when the back plate 11 is thick enough, the electronic control accommodating space 14 may be directly formed on the inner side surface of the back plate 11 in a concave manner, and in this case, the housing 1 may further have a back surface that is planar. In this embodiment, usually, the electronic control module 6 is installed at the bottom of the electronic control accommodating space 14, and the arched portion of the back plate 11 for limiting the electronic control accommodating space 14 is provided with heat dissipation holes corresponding to the electronic control module 6, so as to ensure heat dissipation of the electronic control module 6.
In this embodiment, the depth range of the electronic control accommodating space 14 is preferably 25mm to 30 mm; it can be understood that if the depth of the electrically controlled accommodating space 14 is too large, the amount of rear projection required by the back plate 11 will be large, the manufacturing difficulty is high, the cost is high, and the product will be too bulky; if the depth of the electrical control accommodating space 14 is too small, the installation position of the electrical control module 6 may be insufficient, and the heat dissipation is not good; the depth of the electric control accommodating space 14 in the embodiment is moderate, and the low cost and good heat dissipation of the product can be considered at the same time. However, the design is not limited thereto, and in other embodiments, the depth of the electrical control accommodating space 14 can be adjusted reasonably according to the required volume of the electrical control module 6.
In this embodiment, a cover plate 15 is preferably disposed on the receiving opening of the electrically controlled receiving space 14, and the cover plate 15 is mainly used for dust prevention.
In addition, in this embodiment, the housing 1 further includes two side plates 12 respectively disposed on two opposite sides of the back plate 11, and two limiting portions 13 respectively connected to the two side plates 12, wherein the limiting portions 13 are opposite to the back plate 11, and the back plate 11, the two side plates 12, and the two limiting portions 13 jointly limit two opposite sliding slots 10. The back plate 11, the two side plates 12 and the two limiting parts 13 are preferably integrally formed, so as to facilitate mass production of the housing 1. In addition, in the embodiment, the limiting portion 13 is configured as an integral plate-shaped member extending along the corresponding side edge, it can be understood that the limiting portion 13 is located at the front side of the display screen 22 and is an appearance member to a certain extent, and the arrangement of the integral plate-shaped member can ensure that the appearance of the liquid crystal display device is good; of course, in other embodiments, the position-limiting portion 13 may also include a plurality of plate-like members intermittently disposed in the extending direction of the corresponding side edge, so as to achieve the position-limiting effect.
However, the design is not limited to this, in other embodiments, the housing 1 may also be configured to set the side plates 12 as arc plates instead of providing the limiting portions 13 on the side plates 12, specifically, the cross section of each side plate 12 perpendicular to the extending direction of the corresponding side edge is configured as an arc protruding in a direction away from the other side plate 12, so as to form two sliding slots 10 on the inner side surfaces of the two side plates 12.
In the technical scheme of the invention, the electronic control accommodating space 14 for installing the electronic control module 6 is formed by partially extending the inner side of the back plate 11 outwards, and the accommodating port of the electronic control accommodating space 14 is positioned on the inner side surface of the back plate 11, so that compared with the technical scheme that the electronic control accommodating space 14 is formed by connecting the small split back shell and the back shell, the back surface of the back plate 11 can be prevented from being formed with a split connecting part which is exposed to the outside, thereby enhancing the integral style of the liquid crystal display device and improving the user experience. In addition, in the invention, when the liquid crystal display device is assembled, the display screen 22 and the optical film group 23 can be firstly installed on the supporting frame 21 to obtain the display module 2 in a module whole, and then the display module 2 is integrally installed in the two sliding grooves 10 respectively through the frame bars 211 on the two opposite sides of the supporting frame 21 in a sliding manner, so that the display module 2 can be installed on the shell 1, and therefore, on one hand, the modularized installation of the liquid crystal display device is realized, the component zero-dispersion property of the liquid crystal display device is reduced, the assembly process is simplified, and the assembly efficiency is improved; on the other hand, the assembling screws between the shell 1 and the display module 2 can be saved, the cost is saved, the appearance simplicity of the shell 1 is improved, the installation space required by the assembling screws is reduced, the liquid crystal display device is thinner, and the effect of a narrow frame is achieved. In addition, in the invention, when the display module 2 is assembled by a worker, the worker does not need to carry the shell 1, and the assembling operation of the worker is more convenient.
Referring to fig. 7, the inner surface of the back plate 11 is provided with a positioning groove 16 at the peripheral edge of the receiving opening, and the peripheral edge of the cover plate 15 is overlapped with the positioning groove 16 so that the front plate surface of the cover plate 15 is flush with the inner surface of the back plate 11. It is understood that, when no other component is interposed between the cover plate 15 and the positioning depressed groove 16, the depth of the positioning depressed groove 16 is equal to the thickness of the cover plate 15. In this embodiment, the front panel surface of the cover plate 15 and the inner side surface of the back plate 11 are arranged in parallel and level, so that the whole back surface of the reflector plate 232 can be attached to the inner side surface of the back plate 11, and the display defect of different brightness caused by different distances from the back surface of the reflector plate 232 to the cover plate 15 and the back plate 11 is avoided. However, the design is not limited to this, in other embodiments, a plurality of positioning pillars with suitable height may be disposed in the electronic control accommodating space 14, and the positioning pillars abut against the rear surface of the cover plate 15, so that the front surface of the cover plate 15 is flush with the inner side surface of the back plate 11.
In the present invention, the cover plate 15 is preferably detachably connected to the back plate 11 to facilitate the maintenance of the electronic control module 6. In particular, the cover plate 15 may be, but is not limited to, connected with the back plate 11 by means of screw locking or snap connection; however, the design is not limited thereto, and in other embodiments, the cover plate 15 may be further fixed to the positioning sinking groove 16 by bonding.
In the present embodiment, further, the cover plate 15 is a plastic plate. Specifically, the cover plate 15 may be, but is not limited to, a PVC plate, a PC plate, or the like, and plastics such as PVC plastic, PC plastic, and the like are common plastics, are easily available, and may be prepared into a shape required for the cover plate 15 through a simple cutting process or a stamping process, which is convenient for mass production. In addition, the price of PVC plastic, PC plastic and other plastics is lower, which is beneficial to reducing the product cost. However, the design is not limited thereto, and in other embodiments, the cover plate 15 may also be a metal plate, such as but not limited to an iron plate, an aluminum plate, and the like.
It can be understood that if the cover plate 15 is too thick, on one hand, the material is more and the cost is higher, and on the other hand, the cover plate 15 is not convenient to be prepared by a cutting process or a stamping process; if the cover plate 15 is too thin, the cover plate 15 is easily bent and deformed, which is disadvantageous in mounting the cover plate 15.
