Description of the Invention: [Technical Field] The present invention relates to a display device, and more particularly to a display device having a screen protection function. [Prior Art] [0002] With the rapid development of multimedia technology, flat display devices (including liquid crystal display devices, organic light-emitting display devices, plasma display devices, and field emission display devices, etc.) have been more and more widely used in individuals. Digital assistants, notebooks, digital cameras, mobile phones, televisions and other electronic products. Among them, liquid crystal display devices have the fastest development and the largest output. [0003] In a liquid crystal display device, in order to make the display surface clear, the liquid crystal screen needs to be kept clean. Since the conventional liquid crystal screen is directly composed of a soft material, once it is washed by a hard object, it may cause irreparable damage. [0004] In the prior art, before the liquid crystal display is kept portable, in order to prevent the liquid crystal screen from being contaminated or damaged by a hard object, a hard glass plate is fixed on the casing of the liquid crystal display device as a screen protection. . Further, in order to facilitate the assembly, repair or replacement of the liquid crystal display device, when the glass plate is usually fixed to the front end of the liquid crystal display screen, a gap is left between the glass plate and the liquid crystal display. However, in order to prevent the liquid crystal display from being initially displayed, the water molecules in the gap are condensed on the glass plate due to uneven heat and humidity to generate white fog, which in turn affects the display effect, and the gap needs to communicate with the outside air. However, when the gap communicates with the outside world, foreign pollutants easily enter the gap to contaminate the screen, which still affects the display effect. 095149786 Form No. A0101 Page 3 of 14 1003149276-0 1345119 __ 100 Years U4 Month 29 Correction Replacement Page [Invention] [0005] In view of the above, it is necessary to provide a screen protection function and better display effect. Display device. A display device includes a housing, a display module and a transparent shield. The housing has a receiving cavity, and the display module is disposed in the receiving cavity of the housing. The transparent shielding plate is disposed on the light emitting surface side of the display module. The osmotic layer is made of a porous ceramic material and has a pore size range of 0.15 0 // m. [0007] Compared with the prior art, the display device comprises a transparent protective plate and a gas permeable layer made of a porous ceramic material, which is used between the display module and the transparent protective plate due to the gas permeable layer when initially used. The gap communicates with the outside air, and water molecules in the gap can freely enter and exit through the gas permeable layer, thereby reducing the amount of water molecules hitting the transparent protective plate, thereby preventing excessive water molecules from being transparent due to uneven heat and cold. Condensation on the protective plate produces white fog. Moreover, since the holes in the gas permeable layer are tortuous, the flying dust is difficult to pass, so that it can be removed before the gap is communicated with the outside, and the dust such as dust from outside can be prevented from entering the gap, thereby ensuring the clear display of the display device. Therefore, the above display device has the advantages of a screen protection function and a better display effect. [0008] The display device will be further described in detail below with reference to the accompanying drawings and embodiments. [0009] Referring to FIG. 1 and FIG. 2, the display device 10 of the preferred embodiment 1 of the present invention is a liquid crystal display device. The utility model comprises a display module 11, a casing 12, a transparent 095149786, a form number A0101, a fourth page, a total of 14 pages, 1003149276-0, 1345119, and a replacement of the gas layer 13 and a transparent protective plate 14 on April 29, 100. The housing 12 has a receiving cavity 121 and a top surface 122. The display module 11 is a liquid crystal display module disposed in the accommodating cavity 121 of the housing 12 . The transparent shield 14 is disposed on the light emitting surface 111 side of the display module 11. The gas permeable layer 13 can be disposed at the edge between the liquid crystal display module 11 and the transparent shield 14; in this embodiment, the gas permeable layer 13 is located on the top surface 122 of the housing 12 and is connected to the transparent shield 14. [0010] The transparent protective plate 14 is used to protect the liquid crystal display module 11 from hard objects and scratches, and the material thereof may be glass or transparent plastic. [0011] The gas permeable layer 13 is used to connect the gap 15 between the liquid crystal display module 11 and the transparent shield 14 to the outside air. The gas permeable layer 13 is formed of a porous ceramic material which may be an oxide ceramic and non-oxide composite ceramic material, a glass material, a glass ceramic material, and other composite ceramic materials. In the preferred embodiment, the porous ceramic material is an alumina porous ceramic material. The porous alumina ceramic material can adopt an asymmetric structure, and porous ceramic materials having pore diameters from 〇1 to 50/zm and different pore diameters can be prepared through different process conditions. The structure of the gas permeable layer 13 can be determined according to environmental needs. For example, when the ambient humidity is large, the contact surface of the gas permeable layer 13 with the gap 15 and the outside can be increased to improve the exchange speed of the air in the gap 15 with the outside air. In this embodiment, the structure of the gas permeable layer 13 is a rectangular frame sized to fit the casing 12, and the upper and lower sides thereof are approximately parallel to the liquid crystal display module 11 and the transparent shield plate 14. The gas permeable layer 13 can be fixed to the casing 12 and the transparent shield 14 by means of an adhesive. Of course, it can also be fixed to the casing 12 and the transparent shield 14 by a screw-fitting structure or a snap-fit structure. [0012] When the display device 10 is initially used, the display module 095149786 is formed by the gas permeable layer 13 form number A0101, page 5 / page 14 1003149276-0 1345119 __ April 29, revised correction page 11 and transparent shield 14 The gap 15 is in communication with the outside air, and the water molecules in the gap 15 can freely enter and exit through the gas permeable layer 13, thereby reducing the amount of water molecules hitting the transparent shield 14, thereby preventing excessive water molecules from being hot or cold. Both of them condense on the transparent protective plate 14 to generate white mist. Since the gas permeable layer 13 is formed of a porous material, the pores therein are tortuous, the gas can pass but the dust is difficult to pass, so that the gap 15 can be prevented from entering the gap before the air is communicated with the outside air. 15, to ensure that the display device is clear. Further, if a porous material having a relatively small pore diameter is used to prepare the gas permeable layer 13, the dustproof effect can be further improved. Referring to FIG. 3, a display device 20 according to a second embodiment of the present invention. The display device 20 is similar to the display device 10. It also includes a display module 21, a housing 22, a gas permeable layer 23 and a transparent shield 24; the difference is that a periphery of the top surface 222 of the housing 22 is formed. The flange 223 defines a second accommodating cavity (not shown), and the gas permeable layer 23 is located in the second accommodating cavity. The gas permeable layer 23 includes a bottom portion 231 and a bent portion 232 away from the display center of the display device 10. The top portion 231 cooperates with the bent portion 232 to form a third receiving cavity (not shown) to receive the transparent protective plate 24. Since the casing 22 is provided with the flange 223 and the gas permeable layer 23 has a bent portion 232 which can surround the transparent shield 24, it is more advantageous to securely fix the transparent shield 24. Referring to FIG. 4, a display device 30 according to a third embodiment of the present invention. The display device 30 is similar to the display device 10, and includes a display module 31, a casing 32, a gas permeable layer 33 and a transparent shielding plate 34. The difference is that a plurality of through holes are provided at the edge of the transparent shielding plate 34. 341, and a plurality of through holes 341 095149786 Form No. A0101 Page 6 / Total 14 pages 1003149276-0 1345119 On April 29, 100, the nuclear replacement page is located above the gas permeable layer 3 3 . Since the plurality of through holes 3 41 make the hole permeable material layer 33 have more surfaces connected to the outside, it is more advantageous to increase the exchange speed between the air in the gap 35 between the liquid crystal display module 31 and the transparent shield 34 and the outside air. . It can be understood that the through hole 341 can also be filled with a porous material. Referring to FIG. 5, a display device 40 according to a fourth preferred embodiment of the present invention. The display device 40 is similar to the display device 10, and includes a display module 41, a casing 42, a gas permeable layer 43 and a transparent shield 44; the difference is that the gas permeable layer 43 is composed of a plurality of porous gas permeable units 431, 432. The porous venting units 431, 432 may have different shapes; in this embodiment, the porous venting units 431, 432 are strip-shaped. Dividing the gas permeable layer 43 into a plurality of gas permeable units 431, 432 facilitates the formation of the gas permeable layer 43 by selecting a quantity of porous material in accordance with environmental humidity requirements. In addition, it can be understood that the gas permeable layer 43 can be composed of only one gas permeable unit 431, but it should be noted that the shell 42 and the transparent shield 44 having the porous gas permeable unit 431 are not supported therebetween, and are supported by other materials. In order to keep the transparent protective plate 44 flat. [0016] It can be understood that the display module in the display device is not limited to the liquid crystal display module, and may be replaced by other display modules, such as an organic light emitting display module, a plasma display module, and a field emission display module. That is, the matching structure of the above casing, the gas permeable layer and a transparent protective plate can be used for the organic light emitting display device, the plasma display device and the field emission display device. [0017] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be equivalently modified or changed in accordance with the spirit of the present invention.
