New Description: [New Technology Field] This creation is about the development of a dimming diffusion film that is designed to provide a dimming diffusion film with both dimming and diffusion functions. The use of the diaphragm to achieve thinning requirements. [Prior Art] For the rapid advancement of the multimedia society, most of them benefit from the dramatic advancement of semiconductor components or human-machine display devices. In terms of displays, cathode ray tubes (CRTs) have excellent display quality and Economical, direct marketing 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, the right is predicted by the trend of energy saving. The cathode ray tube has many problems due to space utilization, but is light. , thin, short, small: the demand for the prime price / rate can not effectively provide a solution. Therefore, have a high two::. Liquid crystal with good utilization rate, low power consumption, no radiation, etc. = the mainstream of the market. It is worth noting that since the liquid crystal display is provided for the liquid crystal surface; it does not emit light, so it must be obtained by the backlight module. Sufficient ==: The liquid crystal panel achieves the effect of display, and the optical mode is an exploded view of the structure of the back-to-back group. The back-slice-reverse_ and the light of the backlight module 1 are optical in the figure. The diaphragm has a three-piece configuration. In the prior art, the reflection sheet 12 is disposed in the frame 11, and then the M410225 light guide plate 13 is disposed on the reflection sheet 12, and then the three optical films 14 are disposed one by one on the light guide plate 13.

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 The three optical films 14 are arranged on the 13 as an example. Since the three optical films 14 are all separate components, the assembly needs to be repeated three times. Such complicated assembly actions are caused by the assembly cost and working time of the backlight module. The main factor. In addition, since the production of the above three optical films is required to be cut twice to achieve the result, the cost and working hours of the cutting are also increased by $. [New content] The enhanced diffusing film of the present invention mainly provides a function of concentrating the lightening and diffusing functions in a single film, and when used in a backlight module, the use of other optical films can be reduced, and the cost of the assembly is reduced.
