The backlight module, the group 1 〇〇 includes a backlight 110, at least an optical film 12G, and at least a support structure 13 (). The optical film 12 is disposed above the backlight 11G, and the support structure (10) is disposed on the backlight 110 for supporting the optical film 120 on the backlight 11 to prevent the optical film 120 from scratching itself. The situation of the song, which affects the overall backlight effect. The backlight 110 of this embodiment is, for example, a Cold Cathode Fluorescent Lamp (CCFL), a Hot Cathode Fluorescent Lamp (HCFL), a Light-Emitting Diode, and an LED. ), Organic Light Emitting Diode (OLED), Electro-Luminescence (EL) or Flat Fluorescent Lamp (FFL).

The sealed chamber 114 is first formed into a vacuum state, and then the discharge gas 117 is placed, for example: Xe An inert gas such as neon (Ne) or argon (Ar) may also be a mercury-containing gas, thereby generating an intensifying reaction to generate ultraviolet light. It is worth noting that the back source 110 of the present embodiment may be a mercury-containing flat lamp (e.g., a cold cathode lamp), that is, the sealed chamber 114 of the backlight U0 contains a pump component. The backlight 110 of this embodiment may also be a mercury-free flat lamp, but is not limited thereto, and other suitable light sources may also be used. As shown in FIG. 1 , the first substrate 111 is made of a transparent dielectric material, such as glass, for causing the light of the backlight 110 to be emitted from the first substrate m. The second substrate 112 is made of a dielectric material ( For example, glass), a reflective layer 112a may be formed on the surface of the second substrate 112 to reflect the light emission so that the light emission can be concentrated from the first substrate 111. The frame 113 is made of a dielectric material (e.g., glass) to support the overall structure of the backlight 110. The support post 118 is disposed in the sealing chamber 114 for supporting between the first substrate m and the second substrate 112 to increase structural stability and ensure the first substrate 1 when the sealed chamber n4 is evacuated. The second substrate 112 is not crushed by external atmospheric pressure. A phosphor layer 119 is formed on the inner wall surface of the hermetic chamber 114 for emitting visible light upon being excited by ultraviolet light. Referring to Figures 1 through 3, the cross-sectional views of the backlight module according to the first embodiment of the present invention are not provided with an optical film. The first electrode 115 and the second electrode 116 of this embodiment may be formed on the inner wall surface of the hermetic chamber 114 by using thick film printing, development etching or vapor deposition, for example, in the form of an internal electrode, as shown in FIG. Or the outer wall surface (ie, in the form of an external electrode, as shown in FIG. 2), and the first electrode 115 and the second electrode 116 may be covered with a dielectric layer 114a formed of a dielectric material to prevent excessive discharge current discharge. In the case, the first electrode 115 and the second electrode 116 are prevented from being damaged by the discharge current. It is worth noting that the 'electrode 115 and the second electric #116 may be arranged in a staggered arrangement on the same plane (ie, in the form of horizontal discharge, as shown in FIGS. 1 and 2), or may be separately Formed on two perpendicularly opposite surfaces to form a vertical discharge (ie, in the form of a horizontal discharge, as shown in Figure 3). The optical film 120 of the present embodiment is, for example, a diffusion sheet, a ruthenium sheet, a brightness enhancement film (BEF), a reflective brightness enhancement film (Dual Brightness Enhancement Film; DBEF), and a non-multilayer film reflection polarizer. (Diffused Reflective Polarizer Film; DRPF) or any combination thereof, which is disposed above the backlight Π0 for enabling the light source of the backlight source 110 to perform optical improvement operations for different purposes. The backlight 110 and the optical film 120 have a predetermined spacing D therebetween, for example, substantially between 7 mm and 15 mm, preferably 1 mm, so that the light output of the backlight 110 can be uniformly mixed.

The supporting structure 130 of the embodiment is used for supporting between the backlight Π0 and the optical film 120, and the supporting structure 130 is made of a light-transmitting material, preferably a high-temperature resistant material, for example: transparent acrylic (PMMA) material, . Transparent polycarbonate (PC) material or glass material. When the backlight 110 is, for example, a flat lamp, the support structure 130 may be disposed on the first substrate 111 of the backlight 11A. The support structure 130 is, for example, cylindrical, rectangular, elongated, pyramidal, inverted pyramid or tapered (as shown in Figures 5A-5E), 10 200846749, for example, by means of adhesion On the backlight UG. The supporting structure i30 has a supporting plane 131 whose area is, for example, substantially 5W to 2 (between W, preferably 15 coffee 2), thereby directly contacting the optical film 120 for stably supporting the optical film m In order to avoid the deflection of the optical film 120, in particular, the large-sized backlight module can stabilize the overall structure by the support structure 130. Since the support structure 13 is made of a light-transmitting material, the backlight can be avoided. The source UG is affected by the support structure 13〇, and a situation in which the color of the light is uneven. For example, when the optical film 120 is, for example, a diffusion plate, the diffusion plate can be prevented due to the support structure 13〇, and thus the diffusion plate The thickness of the film itself can be further reduced (for example, from 2 mm to 1.5 mm) without causing structural deflection due to too thin, so that the optical film 120 can further reduce the thickness to reduce the cost and achieve a thinning effect. The number of support structures 至少3〇 (at least one support structure 130) and the position (for example, disposed at an intermediate position of the backlight 11()) of the embodiment may correspond to the size or overall of the backlight module 1〇〇. The structural strength is determined to firmly support the optical film 120 on the backlight 110. Therefore, when the backlight module is used, the support structure of the embodiment can stably support the optical film on the backlight to avoid the optical film. In the case of deflection due to heat or its own weight, the optical improvement effect of the optical film and the overall structural strength are ensured, and the thickness of the optical film can be further reduced to reduce the cost and achieve a thinning effect.

Hereinafter, only the difference between the embodiment and the first embodiment will be described, and the similarity is no longer here.赘11 200846749. Compared to the first embodiment, the support structure 130a of the second embodiment may be directly integrally molded on the backlight 110. When the backlight 110 is, for example, a flat lamp, the support structure 130a may be directly integrated. On the first substrate 111, the support structure 130a is formed, for example, by injection molding or molding. Thus, the support structure 130a of the second embodiment can be straight. Formed on the backlight 110 to firmly support the optical film on the backlight to avoid deflection of the optical film.
