New description: [New technical field] This creation (4) and (4) backlight module j reduce the thickness of the backlight module to achieve thinning requirements, and Improve the structure of the light guide plate in the 杈 group. [Prior Art] Each press: The liquid crystal display generally used in the information device can be selected according to the requirements of the design of the Beige, or the direct-down or module structure; as shown in the figure - the side-lit backlight Schematic diagram of the basic structure of the mold, the end portion of the light guide plate 30 is a human light surface 3 i, and the new surface portion is divided into a light exit surface 3 2 , and the light of the light source 2Q can be shot from the light incident surface 31, and then the light guide plate 3 The front surface of the Q is 3 2 shots, 4 M294665 to achieve the effect of the light source display. 〇 is the ^^ domain group exists in the town defect, which: - because the light guide plate 3 into the money 2 (3 diameter, the light guide plate 3 ◦ narrow out ==, the original 2 〇 toward the light guide plate 30 - side light effect ;=: The second iron builds up the light guide plate to increase the light area of the light guide plate, that is, it will be 1_ child degree, it does not meet the requirements of light, thin, short and small. The angle of the light emitted by mu is 32 shots Λ 光线The light-emitting surface 2 of the neighboring person's glossy surface 31 emits 'forming a bright spot', thereby causing the backlight module to be bright and dark. [New content] Light, ΐ, I, 'This creation can not only reduce the thickness of the backlight module, And the problem of uneven brightness. The first month of 杈, and 'out of the shot eight = lead and the light of each light source is formed by the light beam of the ^ 1 field and the light from the expected protrusion on the protruding part, on the top; Among them, the diffusion plus 4 materials (four) on the inclined surface ^ each treatment light travel road structure, the sighing face can be broken every [implementation] M294665 in order to enable your review committee to understand the structure of the creation, and the overall operation The method is described as follows: The light guide of the thin backlight module The structural improvement is mainly to improve the light guide plate in the side light type backlight module structure. As shown in the second picture and the Le three figure, the light guide plate 3 of the integral side light type backlight module is the light input end portion. Face 3 1, the front part is the light-emitting surface 32, and a plurality of light sources 2 〇 are set on the human light surface 3! 'As shown, each light source 2 〇 can be a point light source, such as a light-emitting diode, so that The light of the light source 2 can be self-guided, and the light surface 3 of the light-emitting panel 3 is emitted from the light-emitting surface 3, and then the light-emitting surface 3 2 of the front surface of the light guide plate 3 is emitted to achieve the effect of the light source display. 0 is formed at the entrance surface 3丄, a protrusion 3 is formed, so that the height H1 of the protrusion 3 3 is higher than the height 导 of the light guide plate 3: and the height ui of the shirt portion 3 3 is greater than the light source 2 Q straight ^ The light of 20 is incident by the protruding portion 33, so that the light source 2〇: ^ the first line can be entered into the light guide plate 3q by the protruding portion 3 3, and the light guide light is emitted from the direction of the guide 3 〇 = New Light 2 = the thickness of the force, can meet the light, thin, short heart and the protrusion 3 3 toward the light guide plate and the slope of the slope is 3 4, and (4) the slope ^ formation The angle is formed to form various differentities on the inclined surface 34 = diffusion processing: rr structure ..., so that the pass === is formed in her 34 to form different forms of concave and convex grooves, 6 M294665 three and fourth pictures As shown in the embodiment, the groove may be disposed on the inclined surface 34 in a lateral or longitudinal direction, wherein the v-shaped groove of the partial region may have an irregular, non-continuous change in angle, as shown in FIG. 5; The shape of the groove can also be as shown in the sixth figure, and the inclined surface is composed of more than one cut surface VI, V2. Of course, the light-adjusting structure 3 4 1 can also be of different forms = road 1 As shown in the embodiment of the seventh figure, the pattern of the pattern may be an arc:: ” The curved grain is expanded outward at the center of the light source=may also be a plurality of dots, as shown in the eighth figure; The distribution of money μ, (4) near the light source is densely packed, but the source is more sparse or larger, and the light is scattered to form a uniform light effect; in addition, the sub-vehicle is reluctant: The shape groove is as shown in the embodiment of the figure IX, and the dimming structure can be used by the above various forms. The uneven injection of 'and effectively improve the light and darkness of the first module and the brightness of the original line provide the side-light type backlight module frame - better and clearly shown in the figure, the original creation, similar, similar All of them are within the special test. ...is the creation purpose of this creation and the patent application model M294665 The first picture is the entanglement of the conventional backlight module.
