New Description: ^ [New Technology Field] This creation is about diffusing the brightness enhancement film. It is intended to provide a diffusion enhancer with both diffusing/dispersing and adding functions. It can be reduced when applied to a backlight module. Less use of other optical films to achieve thinning requirements. [Prior Art] For the rapid advancement of the multimedia society, most of the benefits are due to the dramatic advancement of semiconductor components or human-machine display devices. In terms of displays, cathode ray tubes (CRTs) have excellent display quality. Compared with its economy, it has been monopolizing the display market in recent years. However, for the environment in which most individuals operate the terminal/display device on the table, or from the perspective of environmental protection, if the energy saving trend is predicted, the cathode ray tube still has many problems due to space utilization and energy consumption. The need for light, thin, short, small, and low power consumption cannot be effectively addressed. Therefore, liquid crystal displays with superior properties such as high quality, good space utilization, low power consumption, and no radiation φ are gradually becoming the mainstream of the market. It is worth noting that the liquid crystal panel itself does not emit light in the liquid crystal display. Therefore, it is necessary to provide the backlight unit to provide the surface light source required for the liquid crystal panel to make the liquid crystal panel achieve the display effect, and at the same time obtain sufficient brightness and contrast. As shown in the first figure, it is an exploded view of a conventional backlight module. The backlight module 1 is mainly composed of a frame 11, a reflection sheet 12, a light guide plate 13, and a plurality of optical films 14. The optical film in the figure is composed of three pieces. The conventional backlight module 1 is assembled in such a manner that the reflection sheet 12 is disposed in the frame 11, and then the light guide plate 13 is disposed on the reflection sheet 12, and then three optical 5 M337075 The diaphragms 14 are disposed one by one on the light guide plate 13. Finally, the frame 11, the reflection sheet 12, the light guide plate 13, and the plurality of optical films 14 are carried by a metal frame 15 to complete assembly. / It is worth noting that in order to improve the overall brightness and brightness of the backlight module 1, a plurality of optical films (such as a diffusion sheet, a brightness enhancement sheet or a reflective polarizer) are usually disposed on the light guide plate 13 in this figure. For example, three optical films 14 are disposed on the light guide plate 13. Since the three optical films 14 are separate components, the assembly needs to be repeated three times. Such complicated assembly actions are caused by the assembly cost of the backlight module 1 φ. And the main factors for the increase in working hours. In addition, since the production of the above three optical films is required to be cut three times, the cost and working hours of the cutting are also increased. [New content] The creation of "diffusion enhancer" mainly provides a kind of diffusion and light enhancement function concentrated in a single diffusion enhancer. When it is used in a backlight module, it can reduce the use of other optical films to reduce costs and Assembly time, and φ can achieve thinning requirements.

Structure, as shown in one embodiment of the diffusing film in FIG. 14, the lower surface of the carrier 21 is provided with a diffusion surface layer 211, and the brightness enhancement layer 22 is also disposed on the lower surface of the diffusion surface layer 211, the brightness enhancement layer 22 is provided with a plurality of parallel structure 221 structures, and the lower surface of the light guide plate 43 is provided with a plurality of vertical alignments. • Prism structure 431 〇 It is worth mentioning that this creation has the following advantages over the Xia system: 1, single diffusion A light diffusion sheet and credit i.e. having both functions. 2. When the diffusing film is applied to the backlight module, it can reduce the use of other optical films to achieve thinning requirements. 3. It can reduce the use of other optical films, thereby reducing cost and assembly time. 4. This creation can adjust the thickness or material of the carrier as needed to form a thinner φ degree sheet or a thicker sheet. 5. The diffusion enhancer may further comprise an ultraviolet absorber, wherein the ultraviolet absorber prevents oxidation and deterioration of the diffusion enhancer and yellowing, and the emitted light passes through the deteriorated diffusion enhancer to form a slightly yellow light, and further It affects the light quality and reduces the function of diffusion and light enhancement. As described above, the present invention provides another preferred dimming film for a backlight module, and an application for a new patent is filed according to law; however, the above embodiments and drawings show one of the preferred embodiments of the present invention. It is not limited to this creation. Therefore, any similarity or similarity to the structure, installation, and features of this creation should be within the creation purpose of this creation and the patent application scope is within 12 M337075.
