[Prior Art] In 3C products, in order to enhance the aesthetics and the convenience of function display, usually a small screen is set on the outer casing, which can not only emit a variety of color light, but also display simple information such as time, working state and function mode. , making 3C products more distinctive. The small screen usually adopts liquid crystal display technology, but the liquid crystal display device has a complicated structure and high cost. It is used for the 3C product shell to enhance the aesthetic appearance and display simple functions, which is somewhat worth the loss. In order to solve this problem, some people use a light-emitting diode (LED) technology, such as the control of LED dot matrix by a mobile phone as disclosed in Chinese Patent No. 20062Ό134520, and display simple information such as time and caller ID. However, due to the small number of LED dot matrix technology, the displayed image is not clear, the luminance is not uniform, and the LED array is bulky, which is not conducive to the development of 3C products, which is light and short, whether in the button area or the decorative bright area or In the function display area, more and more products use a backlight film set with a light-guiding film to provide a backlight to 'illuminate these button areas or directly display patterns to enhance the decoration or directly by the established figure # display function mode and other simple information . Light guiding films commonly used in backlights today include a polycarbonate film (pc film) or a silicone film. Among them, the polycarbonate film has a certain degree of 6 1364011, which can ensure better touch (8), but the processing is not easy, and the touch is not the same as the kelly rubber overcoming the polycarbonate _ plus 1 and the touch is not good. 'But (4) the tree has a secret, but the reflector on the bottom layer will H scatter the large light source out of the light guide layer, making the backlight brightness insufficient. It is very important that the wells are supplied with a uniform film with good brightness uniformity, high brightness and easy processing. The human inventor's sense that the above-mentioned insufficiency can be improved' proposes a present invention which is designed to effectively improve the above-described deficiency. SUMMARY OF THE INVENTION A technical problem to be solved by the invention is to provide a light guiding film group which has excellent luminance uniformity, high brightness, and easy processing. Another technical problem to be solved by the present invention is to provide a display device having a light guiding film group having excellent luminance uniformity, high brightness, and easy processing. In order to solve the above first technical problem, the present invention provides a light guiding film set comprising a rigid light guiding film and a soft light guiding film, the soft light guiding film being attached to the rigid light guiding film, the soft guiding The light film has a first surface, and is characterized in that a pattern is formed on the first surface, and a region other than the first surface pattern is adhered to the rigid light guide, and the pattern is sandwiched between the soft light guiding film and Between rigid light guiding films. The pattern is composed of a plurality of bumps of the same material as the soft light guiding film, and may also be composed of pits formed on the first surface of the flexible light guiding film. In order to solve another technical problem of the present invention, a display device includes a light guiding film group and at least one light source disposed on a side of the light guiding film group, wherein the light guiding film group includes/rigid guide a light film and a soft light guiding film, the soft light guiding film having a first surface on which a region other than the surface pattern of the second surface of the jf is formed and attached to the rigid light guiding film, the light guiding film Between the rigid light guide film and the third light, the pattern is illuminated and becomes visible. The present invention also provides a display device in which a film group and a per-guide group are paired with at least a predetermined light source, and J is provided with a side of the pair of light guiding film groups, characterized in that the first first rigid light guiding film And a soft light guiding film, the soft guiding sputum has a surface of the first surface - the surface of the first surface is off, on the rigid light guiding film, the figure J is sandwiched between the soft light guiding film and the job ^ The group is ordered. The sequence of the 4'-thlight-guide film is thinned. * The soft guide film of the second group of guides has a gap between them. w, , mouth, Chu Zhe, Zeng, gap, when the predetermined light source is selectively brightened =: Γ, the pattern of the second light guiding film group is relatively lit and becomes visible. The = two light guiding film group further includes a reflection sheet sandwiched between the reflection sheet and the soft light guiding film. The light guiding film group comprises a rigid light guiding film and -==shoot=forming, on the soft light guiding film, the rigid light guiding film can be photoamine II 14 which is actually a combination of a soft light guiding film The easy-to-process, rigid light-guiding film is made in the display device, so that the "=; point. The light guiding film group is applied uniformly and has high brightness. The other device has a simple structure and low cost; the phase device' display device has micro-products _Short device, the 丄364011 read the second:: The characteristics and technical content 'Please refer to [in fact:] use 'is not used to limit the invention. Please refer to the first picture, too hairy ^ 10 The light guide film group soft material provided by the light guide ^ and the second - (four) method, such as #导二, wherein the material of the light guide film 11 is acid, the guide surface U "dipole, the material is a rigid material, such as The polycarbon is formed by a specific arrangement, and a plurality of bumps iu are formed on the surface 112. The 110° pattern region is sandwiched between the light guiding film ii and the surface of the light guiding film. The structure of the light guide film provided by the second embodiment of the present invention is substantially the same as that of the light guide film group 10, the Cong 21 and the rigid material age. The surface is different in that the light guiding film 21 is formed by the indentation of the indentation pattern 210, and the pattern i is not formed. The age iJi is integrated when the reflective sheet is applied. The guide group is easy to process with the bright film and the branch of the rigid light guiding film, and a gap is formed between the light guiding film, and such as Ϊ ^ ^ Ρ4χ'/φ ^ 1〇0'2〇0 ^ 3〇0 Vertical display effect contains air medium or vacuum) can produce layering _ '5Hai light film group 10 and 20 can be applied to display two to fifth pictures, one, wide. Please refer to group 10, 2〇 and such as . ' 导 from top to bottom superimposed light guide film also includes soft light guide film, = ^, 20 the same 'light guide film group 30 rigid guide her 2 contact surface shape =A = light guide film" with 10, 20 and 30 according to .PD if there is a figure 310, and the light guide film group light guide film 22 盍 蚓 蚓 guide the rigidity of the nine film group 20. For the fourth On the side of the figure, d=fruit=photofilm group...2, ^Europe 100, 200 and 300. When the angle is illuminated, part of the light of 総(10) will be at a certain angle ^1G' if the light is from the light guide film When the critical line of the material will be the portion of the group 10 that does not have the pattern 110, then the light is reflected in the light guiding gland 10 until it is emitted from the other end with respect to the light source ΚΚ, , and 10, but due to the light guiding film. The wood 110 in the group 10 has bumps or indentations, and is provided with a surface that is not flat, so that the light of the light source 100 is scattered so that part of the light rays 101, 102 as shown in the fifth figure are from the light guiding film. In the process of injecting air into the air, if the incident angle is smaller than the critical angle of the light guiding film 11, the partial light rays 101, 102 are from the second surface U3 of the light guiding film 11. And letting the pattern no appear as a visible state on the second surface 113. By the same principle, when the light source 200 is illuminated, part of the light rays 201, 2 are called incident angles smaller than the critical angle of the light guiding film 21, thereby guiding The surface 213 of the light film 21 is emitted to cause the pattern 210 to appear on the surface 213 of the light guiding film 21; when the light source 300 is illuminated, the incident angle of the partial light rays 301, 302 is smaller than the critical angle of the light guiding film 31, thereby being guided from the light guiding film The surface 313 of the film 31 is emitted so that the pattern 310 is present on the surface 313 of the light guiding film 31. Moreover, since the incident angle of the light rays 2〇1, 2〇2 which are emitted from the surface of the light guiding film 21 is small, it is smaller than the light guiding film 21_ The angle, and therefore also less than the U) _ boundary angle of the same material, so that the tree member penetrates the light guiding film group 1 〇, and then takes out the second surface Φ 113 of the light guiding film 11 so that it can also be emitted from the second surface 113 See pattern 21 (). The same principle, the pattern 31 也 can also be seen from the second surface 113. The horse has a constant gap between the light guiding film group 1 〇, 20'30, J bar or vacuum Separating two adjacent light guiding positions, so that each light guiding energy reduction is independent according to the above principle of displaying the pattern m with the light guiding film group 10 The pattern is not visible. Therefore, when the light source is turned on at the same time, the patterns 110 ' 210 and 31 同时 are simultaneously seen on the surface 113, and the plurality of patterns do not interfere with each other. = The brightness presented on the second surface ι 3 The light source 200, 300 can be set to be brighter in turn, and the light energy loss when the light is transmitted through the upper layer and the light film group 2 〇 。 。 。 。 。 。 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少 减少The loss can be far away in the light-guiding film group 30. The rigid-reflective sheet is provided with a surface-attached light guide i attached to the soft guide 31, so that the rigid light-guiding film 32 is sandwiched between the reflective sheet and the soft sheet. =====Cap _ can be a coffee light, = show no.
