V [Prior Art] * Products using liquid crystal display (LCD) are very common, and their applications can be seen in notebook computers, display devices, mobile phones, LCD TVs, etc. The application of LCD must use the backlight module to make it emit light and produce a display effect. Therefore, the backlight module actually belongs to the LCD product. Even if it is not an LCD product, it is used in the application field where the light-emitting effect is required. Modules have also become the appropriate choice. Most of the electronic and electrical products with LCDs will also be provided with a marking element for recognizing the brand in the appropriate position of the product. The traditional marking component is presented by flat printing or pasting, or the three-dimensional identification card is bonded. Or embedded in the surface of the product. Some of the identification elements that emphasize the visual effect are designed to be illuminable. Therefore, the illuminating identification element also requires a light source. Since the identification component of the recognition brand is usually small, the light source and the light source are generally disposed under the permeable light-receiving component using a small-volume LED (light-emitting diode), but the LED cannot be used as a light source. The light of the permeable marking element is uniformized, so recently, a backlight module including a light guide plate and an optical film has been applied to the illuminable identification component. In the case of the notebook computer 4 shown in the first figure, it includes a display state 41 for displaying the facet, and the light-emitting identification component 42 is disposed on the back of the display 41, that is, after the display 41 5 M346025 is attached to the host. The illuminating identification element 42 is directly presented on the eye for a special, dazzling visual effect. The second figure shows a structure including an LCD display 41 and a light-emitting identification component 42 having a first backlight module a and a second backlight module β, wherein the first backlight module A has a first a light guide plate A1, a light source A3 disposed on one side of the first light guide plate, a plurality of first optical films A2 (diffusion sheets and cymbals, etc.) disposed in front of the first light guide plate A1, and a first guide The first reflection sheet A4 on the back surface of the light plate A1; and the LCD A5 on the front side of the first-optical film A2. The second backlight module B is disposed at a symmetrical position of the first backlight module a, and has a second light guide plate 趴, a second optical film B2 disposed in front of the second light guide plate β1, and is disposed on the second light guide plate. The second reflective sheet B4 on the back side of the crucible, and the second light source B3 disposed on the side of the second light guide plate B1; the front surface of the second optical film B2 is provided with a light transmissive identification element B5. The first light source A3 and the second light source B3 are respectively driven by current, and the light is projected from the side of the first light guide plate A1 and the second light guide plate B1, and then reflected by the first reflection sheet A4. An optical film A2 and an LCD A5, and a second reflective sheet B4 are reflected through the second optical film B2 and the permeable identification member B5, so that the LCD A5 and the permeable identification member B5 both emit a luminescent effect. The products containing two sets of backlight modules are described. Because each group of backlight modules must have a light source, the manufacturing cost is high, which is undoubtedly a burden on the industry. [New Content] The main purpose of this illusion is to solve the shortcomings of the current electronic and electrical products with multiple backlight modules, and the backlight modules of the mother must be equipped with light sources, so as to increase the manufacturing cost of 6 M346025. The general idea of this creation is to touch the multi-f optical mode _ electronic Wei products, using the *7 group of backlighting cars, the tactics of riding them back to the _ light guide plate, so that the multiple backlights share the same - the light source produces a luminous effect, The cost of borrowing a low light source is based on the technical means of the present invention, including a first backlight mode set in a symmetrical position, a second backlight module, and the first and second back groups respectively have a first guide a light guide plate and a second light guide plate, a light source is disposed on a side of the first light guide plate, and a second light guide reflector is disposed on the other side of the light guide plate, and the first light guide plate is disposed on the side of the light guide light. In addition to causing the first backlight module to emit light, the light secret is reflected from the reflector into the second light guide plate, so that the second backlight module emits light in phase. The H-module has a larger area and can be used as a backlight of the LGD. The second backlight module has a small amount of light and is suitable as a backlight for the illuminating identification component. In addition, this creation can also set two or more sets of moonlight pull groups by the above-mentioned technical means, but still cause the light-reflection generated by the off-wires to be transmitted to the light guide plates of each group of backlight modules. And glow. [Embodiment] The following description will be made in detail with the implementation of the ffi type and the 70-piece Braun solution, so that those skilled in the art can implement it after studying the present specification. The third figure is an embodiment of a multi-backlit backlight with a hybrid backlight module, which includes - as a display 41 t light source - the backlight module - as a backlight 7 M346025 identification component 42 backlight a second backlight module 2, and a reflector 3; wherein the first backlight module 1 includes a first light guide plate Η, at least one light source 13 disposed on a side of the first light guide plate 、 a plurality of first optical films a in front of a light guide plate π, and a first reflective sheet 15 on the back side of the light guide plate 11; the first backlight module 1 is mounted on the back of the LCD 14 as a backlight of the display source. The second backlight module 2 is disposed at a symmetrical position of the first backlight module 1 and has a second light guide plate 21, a second optical film 22 disposed on the front surface of the second light guide plate 21, and a φ The second reflective sheet 23 is disposed on the back surface of the second light guide plate 21; the second backlight module 2 is configured to be mounted on the back surface of the light permeable identification member 24 as a backlight. The reflector 3 has a suitable curvature and can reflect light well. The reflector 3 is disposed on the same side of the first light guide plate 丨丨 and the second light guide plate 21, so that the first light guide plate and the first light guide plate The same side of the light panel 21 is covered by the reflective cover 3; therefore, the length of the second light guide plate 21 is greater than the length of the second optical sheet 22 and the light transmissive identification member 24, so that the position of the reflective cover 3 is The first light guide plate 11 is flush with the same side of the second light guide plate 21. • When the light source 13 is energized, light is projected from the side of the first light guide plate 11, and a part of the light is reflected by the first reflection sheet 15 and exits the first optical film 12 and the LCD 14. The light of the I5 knife is straight out. - the light guide plate U is on the other side, and is reflected by the reflector 3 (as indicated by the dashed line and the arrow in FIG. 3) and projected from the side of the second light guide plate 21 into the conduction, and the light in the first light guide plate 21 Then, the second optical film 22 and the light transmissive identification member 24 are reflected by the second reflection sheet 23 to generate a light-emitting effect. One creation may also set two or more sets of second moon light cores in the symmetrical position of the first backlight module, and 'and each side of the second light guide plate of the second backlight module and the first backlight The side of the first light guide of the M346025 module is covered by the reflector to reflect the light in the first light guide to each of the second light guides.
