New description: [New technical field] The light guide plate can be presented. This creation involves a structure in which the light source is distributed on the light guide plate and has a more uniform brightness design. [Prior Art] The application of the backlight module is very common. For example, notebook computers, monitors, mobile phones, night crystal TVs, and 本n will play Wei (4) side-turn _ domain groups to provide light sources. • The general back group consists of a light guide plate and a light source. For an electronic product w with a thin body thickness, the (four) D is usually used as a system, and the auxiliary light source is disposed on the side of the light guide plate on the side of the light guide plate. Then, a reflective sheet is disposed, and the opposite second side is provided with a plurality of optical films composed of a diffusion sheet and a cymbal sheet, and is surrounded by an outer frame at the periphery of the elements. The light emitted by the system is projected into the person by the light guide plate, and part of the light is reflected by the Φ reflection sheet, and then sequentially emitted through the diffusion sheet and the cymbal sheet. For the smaller size back (4), since the light guide plate has a small bribe, it is only necessary to install the light source on the side of the guide, but the larger size of the back wire group, if the light source is only in the guide U The projected light field is gradually attenuated when it is expected to be on the other side, causing the brightness of the light guide plate to be unevenly hooked. Therefore, it is usually installed in a large area of the light guide plate _ all of which are mounted with a light source, sighing the aforementioned paste light source The problem. The fifth figure shows the light source layout structure of the light guide plate of the conventional backlight module. The plurality of LED light sources 2 are respectively mounted on the light guide plate! The opposite sides of the 5 M361030 light source 2 on the opposite sides are symmetrical with each other. Therefore, when the light source projects light, a problem of low brightness is easily generated between the light sources along the x-direction, resulting in uneven brightness of the entire light guide plate. hook. [New content] The main purpose of the present invention is to solve the problem that the light source unevenness of the light source of the conventional backlight module is caused by the light source unevenness. The main feature of this creation is that the light source disposed on both sides of the light guide plate is changed to its relative position, so that the light projected into the light guide plate can be fully considered, thereby achieving the purpose of brightness uniformity. One of the technical means of the present invention is that the plurality of light sources are respectively disposed on opposite side edges of the light guide plate, and the light sources on the two sides are staggered with each other, thereby projecting light from the opposite sides of the light guide plate into the light guide plate. . A further method of the present invention is to have the same side edges of the light guide plate and have a miscellaneous relationship with the opposite edges of the light guide plate, and the sources are staggered. Another method of magical esoteric creation is when the light source is set in the guide 栊崎, (10) face tender, _ total _, (four) fill light source after the Qing, the opposite side of the light guide plate can also be on both sides of the light guide plate Corresponding to the position where the light source is located, the optical 4#. ___ , , °冓 can be arranged by a plurality of sawtooth, bumps or pits. The X-technical method of this creation is the well green of the light source on the side of the guide _ side. The direction of the slave line and the direction of the light projection of the light source on the opposite side have an angle of 6 M361030, which can compensate for the phase. The difference in brightness produced by the light guide plate when the distance between the two adjacent light sources is different. [Embodiment] The implementation of the creation is described in more detail below with reference to the drawings and component symbols, so that those skilled in the art are studying the specification. The present invention can be implemented according to the light source arrangement structure of the optical module. The main feature is that the plurality of light sources are respectively disposed on opposite sides of a light guide plate, and the light sources on the two sides are staggered. By means of * to project light from both sides of the light guide plate into the light guide plate; the light source is arranged on the light guide plate - there are several embodiments: "First Embodiment" See the figure - Figure 'This creation In the first embodiment, the plurality of wires 2 are respectively disposed on opposite side edges of a light guide plate 1, and the light sources 2 on the two sides are staggered with each other, thereby illuminating the light from the opposite sides of the light guide plate. The side projection enters the light guide plate, thereby arranging, and after the light is projected into the light guide plate, a wider and more uniform coverage can be achieved, thereby making the light guide plate have more uniform brightness. [Second Embodiment] Refer to the second ® ' The second practical aspect of the present invention is that the plurality of light sources 2 are respectively disposed on the two sides of the light guide plate 1 and have a distance S from the opposite side edges of the guide beam, and the two _ vehicles and the two are The staggered distribution, therefore, the recording of the side can project the line of light 7 M361030 to the opposite side and constitute a wide coverage area. Third Embodiment Referring to the third figure, a third embodiment of the present creation The structure of the second embodiment is the same, that is, the plurality of light sources 2 are respectively disposed on opposite sides of a light guide plate ,, and have opposite distances from the opposite side edges of the light guide plate 1 , and the two sides are The light sources 2 are staggered-distributed with each other; only 'the light-edge structure u' capable of reflecting light can be disposed on the opposite side edges of the light guide plate 1 so that the light source 2 can be projected to the opposite side, and the optical structure can be Light reflection, with Mi Between the rear of the complementary light source 2 and the edge of the light guide plate 1 may not directly be projected by the light and the line. The optical structure may be along the length of the king's edge of the light guide plate i, or may be set. Where the two sides of the light guide plate correspond to the position of the light source 2, the optical structure may be formed by a plurality of mineral teeth, bumps or pits. In the third embodiment, the optical structure n is composed of plural The orthodontic teeth are arranged and arranged only at the edge of the light guide plate corresponding to the position behind the light source 2. <<Fourth Embodiment>> Referring to the fourth®, the fourth practical aspect of the present invention is provided on both sides of the light guide plate 1 The plurality of light sources 2' and the light sources 2 on the two sides are staggered with each other, wherein the light projection direction of the light source % on one side and the light projection (4) of the opposite light source 2 have a lost angle, and the tilt angle of the hybrid light source 2a, And the distance between the two light sources 2a can be based on the actual * and the whole can be used to achieve a wider and more uniform coverage when the distance between the two light sources 2 is different. To make the peaches more evenly 8 M361 The brightness of 030. The above mentioned only 4 quilt creations _ lamp / _ _, scale _ according to, "Off 'to, any modification or change in the same spirit' should still be included in this creative meaning . Off M361030 [Simple description of the picture] #图为,,,! A schematic diagram of a first embodiment in which a plurality of sources are disposed on opposite sides of a light guide plate and the light sources on both sides are interleaved.
