First, the combination of the first unit 2A will be described with reference to Figs. 4 and 5. For convenience of explanation, the front is indicated by the direction of the arrow in the figure. The first unit 200 is assembled, firstly provided in the __dust-free environment towel, the front frame 丨 includes a front frame plate u having a central-shaped (four) port 14 and forming a frame shape, and - the front frame plate A first surrounding wall 12 projecting rearwardly from the inner edge, the first surrounding wall 12 surrounding a first space 13 defining a communication with the opening σ 14. Next, a liquid crystal panel 2 and a diaphragm device 3 are sequentially placed in the first space 13 and combined to form a first unit 200 as shown in FIG. 5. Specifically, all the diaphragm devices in the drawings are illustrated. 3 thickness is magnified to facilitate the relative relationship. The above assembly sequence can also be reversed, that is, the liquid crystal panel 2 is stacked on the diaphragm unit 3, and then the front frame 1 is placed. In the present embodiment, the diaphragm assembly 3 is exemplified by a diffusion plate 32 having an optical film 31 adjacent to the liquid crystal panel 2 and a relatively distant optical film 31, and the diffusion plate 32 is away from the optical film 31. The side (rear side) forms 10 201006323 light-incident surface 33, and the optical film 31 forms a light-emitting surface 34 toward the liquid crystal panel side (front side), and the light-emitting surface 34 and the liquid crystal panel 2 are substantially parallel to each other to enter the light-emitting surface 33 and the light-emitting surface. 34 is substantially parallel, and light enters through the light incident surface 33, and is diffused through the diffusion plate 32, and the optical film 31 is uniformized or brightened and processed. The light exit surface 34 enters the liquid crystal panel 2. The periphery of the diffusing plate 32 is tightly fitted with the first surrounding wall 12, and the hollow portion of the front frame plate is closed by the liquid crystal panel 2, so that the liquid crystal panel 2 and the optical film 3 are closed, and the microparticles can be blocked. Ingress and pollution. The optical film 31 may be one of a brightness enhancement film, a diamond lens, a diffusion sheet, and the like. The number may be plural, or even the optical film 31 may be omitted. In particular, 'the diffuser piate 32 is different from the diffuser film or the diffuser sheet in the optical film 31, and the diffuser 32 is not a diaphragm but a thick plate. The optical film 31 is supported and forms a tight fit with the first surrounding wall 12. In fact, in addition to forming a tight fit between the diffuser plate 32 and the first surrounding wall 12, the light-emitting surface 34 can be tightly fitted with the liquid crystal panel 2 (for example, gravity is naturally pressed), or the sealant can be directly closed by the sealant. The periphery between the diaphragm device 3 and the liquid crystal panel 2 may be in a closed state between the liquid crystal panel 2 and the diaphragm device 3, and the periphery between the diaphragm device 3 and the liquid crystal panel 2 is already prior. In the closed state, the first surrounding wall j 2 can be two-piece and only provides a positioning function, or even a removal. Next, the second unit 300 is illustrated. Referring to FIG. 6 and FIG. 7 ′, a rear frame 4 is provided. The rear frame 4 includes a main board 41 and a second surrounding wall 42 protruding from the front side of the main board 41. 41 cooperates with the second surrounding wall 42 to define a second space 43. Then, a light source device 5, a reflective sheet 11 201006323 6 , a rear frame 4 and a circuit control board 7 are stacked and assembled into a second unit 3 图 of FIG. 7 , wherein the light source device 5 and the reflective sheet 6 are in the first Two spaces 43. Similarly, the above assembly sequence can also be reversed, and sequentially stacked on the circuit board 7 - assembling the rear frame 4, the reflection sheet 6, and the light source device 5. Since the light source device 5, the anti-reflection sheet 6, and the circuit board 7 are extremely affected by the fine particles, the second unit 300 is not limited to being assembled in a dust-free environment, and can be assembled in a general environment. In the present embodiment, the light source device 5 is a plurality of cold cathode lamps Q 51, and may be replaced by other LED light emitting elements. Further, the rear frame 4 can be made of a material capable of reflecting light, or the main plate 41 of the rear frame 4 can be coated with a reflective paint toward the side (front side) of the second space 43, so that it is not necessary to mount the reflection sheet 6. The circuit control board 7 can also be integrated with a power supply and a transformer (not shown). Please refer to FIG. 3, FIG. 5 and FIG. 7 simultaneously, after the first unit 2〇〇 and the second unit 300 are respectively combined in advance, and then the first surrounding wall u edge of the frame j and the rear frame 4 The two sides are butted together around the edge of the wall 42 and then combined and fixed by means of bonding, card 9 or lock screw, that is, the assembly of the liquid crystal display 100 of FIG. 3 is completed. In the above assembly step, only the combination of the first unit 200 must be performed in a dust-free environment: as for the combination of the second unit 300, or the combination of the first unit 200 and the first early stage 300, can be performed in a general environment, and The first single 70 200 assembles only the front frame 1, the liquid crystal panel 2, and the diaphragm device 3, so that the required working space can be reduced, that is, the clean room for the work does not have to be as spacious as conventional. Moreover, the present invention saves the iron frame 921 by directly utilizing the front frame 丨 and the rear frame 4 to combine other components. [Fig. 1 and Fig. 12 201006323 (Fig. 1) 'Even if the entire assembly is in the clean room In the middle, the required working space is also relatively small. Referring to Fig. 8, a second embodiment of the present invention is described by combining an edge-light type liquid crystal display device 100'. - Similarly, for the combination A unit 200, for reference, refers to FIG. 9 and FIG. 10 'the first unit 200, which is substantially the same as the first unit 2 of the first embodiment, and the difference is that the diaphragm device 3 has an optical The film dome 31' and a light guide plate 32', the light guide plate 32, and the first surrounding wall 12 are tightly fitted, and then the liquid crystal panel 2 is used to close the opening 14, so that the liquid crystal panel 2 and the optical film 3' The gap is similarly closed to prevent the particles from entering and causing contamination. - In addition, the light incident surface 33 of the diaphragm device 3 and the light exit surface 34 are different from those in the first embodiment, and the light exit surface is different. 34' and the liquid crystal panel 2 are stacked substantially in parallel However, in this embodiment, the relative relationship between the light incident surface 33' and the light exit surface 34 is substantially perpendicular 'and the first circumference of the adjacent light incident surface 33 as shown in FIG. There is a gap 15' between the light incident surface 33' and a portion of the first surrounding wall 12. Next, for the combination of the second unit 3'', referring to FIG. 11 and FIG. 12, the second unit 300' and The second unit 3 of the first embodiment has substantially the same components and assembly methods. The difference is that the light source device 5 in the embodiment is a light tube 51' and a reflector 52', and the installation position is not reflected. On the sheet 6', but between the side of the reflective sheet 6' and the second surrounding wall 42, and partially protruding beyond the second space 43', when the first unit 2〇〇, The two units 300 ′, as shown in FIG. 8 , are combined with each other to form a liquid crystal display 1 ′′, the light source device 13 201006323 5 may be partially accommodated in the light incident surface 33 , and the interval 15 ′ between the first surrounding wall 12 and The light source device 5 of the present embodiment is provided with light on one side, so that the light guide plate 32 is below. Forming a slope (as shown in Figure 1) to facilitate light guiding. If the light source device 5 has a plurality of lamps 51, and a reflector 52', and the light is incident from the two sides or the four sides, the guide The light panel 32 is formed with a horizontal surface to guide light, which is well known to those skilled in the art and will not be described again. Similarly, the assembly step of the second embodiment is only necessary to combine the first unit 200'. In the dust-free environment, as for the combination of the second unit 3, or the combination of the first unit 200 and the second unit 300', the effect as in the first embodiment can be achieved in a general environment. FIG. 13 and FIG. 14 show a variation of the second embodiment, except that the installation position of the light source position 5" is not in the second unit 300" but in the first unit 200". That is, the light source device 5" is also installed first between the light incident surface 33" of the first unit 200" and the first surrounding wall 12", and the second unit ❹ 300" is only the rear frame 4", the reflective sheet 6" and the circuit control board 7" are assembled to each other, but the first unit 200' and the second unit 300" which are separately assembled are butt-joined, and finally assembled into the liquid crystal display 100' as shown in FIG. The light source device 5 of the first embodiment may also be pre-installed in the first unit 200, and finally still combined to obtain the liquid crystal display 100. In addition to the change of the light source position 5", the first surrounding wall 12, 12', 12 And the second surrounding wall 42, 42, 42, may also vary, as exemplified in FIG. 3, since the first surrounding wall 12 and the second surrounding wall 42 are integrally connected after assembly, the first surrounding wall may also be extended. 12 length, making it approximately equal to the 14th 201006323 in Figure 3 around the wall 12 and the second circumference The length of the wall 42 is different, and the rear frame 4 is not provided with the second surrounding wall 42 and is directly assembled and fixed by the end edge of the first surrounding wall 12 against the main board 41. In this case, the reflective sheet 6 is directly bonded to The main board 41 is away from the side of the circuit board 7. In summary, the assembly method of the liquid crystal display of the present invention is divided into four main steps as shown in FIG. 15: S! - with reference to FIG. 5, FIG. 1 and FIG. 13, providing a through opening 14 14', 14" front frame 1, 丨 ', ' in a dust-free environment, in advance on the front frame 1, 1, 1, 1" side of the closed opening 14, 14, 14, liquid crystal panel 2, 2, 2", and diaphragm devices 3, 3, 3" to form a first unit 200, 200', 200" and to provide the diaphragm device 3, 3, 3" and the liquid crystal panel 2 Between 2 and 2, the membrane device 3., 3, 3" has a light-incident surface 33, 33, 3" relatively far from the liquid crystal panels 2, 2, 2"; 7, FIG. 12 and FIG. 14, providing a rear frame 4, 4, 4"', in an environment not limited to a dust-free environment, an electric circuit control panel 7 is disposed on the rear frame 4, 4, 4" side, 7', 7", forming a second unit 3〇〇' 3〇〇, 3〇〇"; 53- with reference to Figures 7, 12 and 13, in the second unit 3〇〇, 3〇〇, Or the first unit 200" is provided with a light source device 5, 5, 5"; and 54— With reference to FIG. 3 and FIG. 8, the first unit 200, 200', 200" and the second unit 3〇〇, 3〇〇, 3〇〇" are connected to each other without being limited to a dust-free environment.
