Description of the Invention: Field of the Invention The present invention relates to a planar 咛 _ which can be made thinner and has high brightness; [Prior Art], ,, 4 See the fifth figure, which is a h-chip structure, It is applied to a double-layer brightness-enhancing film plate (5...,; ==50) which is often used in the past, that is, it is disposed on the guide to form a parallel refractive strip (5 4 'piece (5 4 ) (5 3) The refracting strips are arranged in a staggered manner in 匕531), and the two are shown by the figure, that is, on the two upper and the first plates (5 1 ), and the vertical axis of the X-axis and the x-axis is: :: Shooting strips (""(5 1) above. The 曰 method is superimposed on the light guide plate (5 when the side light source (5 2 ) points the light from the side light source (52) toward the light guide plate (51) In the light guide plate...) has the first layer of 丄 formation - the backlight 'the effect of the 折射 古 古 it it it 先 先 先 先 先 先 先 先 先 先 先 it it it it it it it it it it it it it 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 54) (5" port can pass through the upper layer of brightness enhancement diaphragm (53), which will adjust its refractive area.: Light passes through the lower layer of light, making The light source is concentrated to the ineffectiveness of the ^, and then passed through the brightening diaphragm with the lower brightening diaphragm (5th questioning the upper brightening diaphragm of the light direction (R 4 ^ on the vertical side of the refractive strip is once smashed, can make the second The channel-scattering backlight source is also refracted by the wood, so that the brightness of the backlight light from the light guide plate is more uniform and improved. The above-mentioned refracting of β is the most commonly used M298135 as the brightness of the backlight source. The backlight source is concentrated to a certain degree of self-defense. The version of the film must be controlled at 90 纟, so that the back ..., and the reverse angle of the angle of the central angle of view., ... the group is improved within the normal operating range, although the use of two layers For yeah for y __Γ ” θ 膜 film can make the backlight source brightness uniform, 徊 丝 当 当 摩 、 、 、 、 、 、 、 、 、 、 、 、 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光 背光With the flat-panel display can maintain its thin and light shape, and, and stay wide and wide. If you go to Beibeiyue, the first group can't be too big. When the moonlight module is assembled to the flat panel display, the direction and color of the diaphragm and the sticking strip are brightened.嘑氺κ沾古ή 曰 Μ Μ 反 anti-development effect, and the process must be ρ * and ~ 曰 的 的 “ 夕 夕 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道 道It is necessary to further improve the double-layer brightness-increasing film structure of the 杈 group. [Abstract] The main object of the invention is to provide a backlight for a flat panel display, and a single-use redundant film is used. In order to effectively achieve the back,: "and the effect of the hook, and effectively reduce the thickness of the backlight module is also conducive to the development of thinner and lighter flat panel display. The main technical means used by the package to explain the purpose a light source, a reflector, a diffuser, and an optical brightness enhancement film stacked on the diffusion plate; wherein the optical brightness enhancement film is formed on an optical film structure to form a plurality of micro prism lenses In the array structure, the micro-lens lens array is arranged in an array by a plurality of microprism structures. Each micro-structure is composed of three right-angled faces. M298135 The micro-twist of the above optical brightening diaphragm is composed of two right-angled faces of the field, and the refraction is equivalent to the upper and lower parental arrangement of the double-brightness film. The refraction strip can be effectively raised from the secret of the ancient U A, so that the use of the a 7C film of this creation can reduce the thickness and components of the use of a layer of increasing conditions, not only The manufacturing cost is reduced, and the competition is from the 4th. This makes it possible to reduce the thickness of the whole system and help to develop a lighter and thinner flat panel display. [Embodiment] For the group (30), please refer to the first figure, an exploded view, which includes a light source (31), and a reflector (3 2 ) disposed adjacent to the light source (3 i ) to The light source is refracted to the light-emitting surface; the expansion board (3 3 ) is superposed on the end surface of the reflector (3 2 ) to uniformly diffuse the refracting light source; and the light is added to the film (1 〇) It is disposed on the diffusion plate (3 3 ) to concentrate the source to the light emitting surface to improve the brightness of the light. Please refer to the first and third figures, which is a first preferred embodiment of the single-layer optical brightness enhancement film (1 〇), which has a micro-array lens array formed on the surface of the optical film! The micro-arc lens array structure is mainly composed of an f-number first microprism and a mouth structure (2 〇), and each first microprism structure (2 〇) is composed of three right-angled faces, and The linear distance between two adjacent first micro-twisted structures (20) is 5 〇 micrometers. In addition, the optical brightness-enhancing film has a rectangular shape, so the micro-angular lens array and the ?-structure further comprise the second micro稜鏡 structure (20 a), that is, the t-micro-structure (2〇a) is arranged on opposite sides of the light-enhancing film of M298135. Please refer to the fourth R-y diagram for the creation. The second preferred embodiment has the same structure as the above first embodiment, but the tapered top (2 1,) of each of the first and second micro-turn structures has an arc shape. The two micro-稜鏡 structure (2 〇) ( 2 〇a ) The south-lower system of the cone top can be different, so that the light is passed through the dwarf brother, the second two-twist structure (2) It can be further inserted into the high-first and second micro-structures (2 〇) (20a)* ^ ～ z U a ) for another refraction so that the light can be effectively refracted upwards and the brightness is more uniform. "In addition to the light-brightness, the embodiments of each of the above-mentioned brightness enhancement films are formed by a micro-angular lens array structure composed of a plurality of first::: 尧 mirror structures, and each microprism structure in the 纟The refraction is equivalent to de-greening, and the light is transmitted through the upper and lower staggered layers of the double-brightness-enhancing diaphragm = the refraction strip' is based on the design of the micro-angular lens array: The diaphragm is integrated into one body, and each of the first and second micro-small structures is composed of three right angles and a corner surface, so that the effect of light and fruit concentration can be effectively achieved, compared with the single layer. Zhuang Yu's children, and the structure of the mouth can really improve the brightness; so 'the use of this creation of the brightening film white % _ from the reduction of the use of a layer of brightness enhancement film: 'not only reduce manufacturing costs, but also make the backlight The module can reduce, reduce, and reduce the overall thickness, which helps to develop thinner and lighter. Flat panel display. [Simple description of the drawing] The younger one is the exploded side view of the backlight module.
