先前技術之背光模組主要由光源、導光板、反射板、擴 散板與稜鏡板組成。該光源可設置於導光板一側或兩相 對側並將光束發射至該導光板《該導光板之作用在於引 導光束傳輸方向，使光束由導光板之出光面均勻出射。 反射板相對該導光板之底面設置，以將由導光板底面出 射之光束再次反射入該導光板内，提高光束之利用率。 擴散板與稜鏡板相對導光板之出光面依次設置以使由 導光板出射之光束分佈更加均勻，進而提高液晶顯示器 面板之輝度與均勻性。 剛由於發光二極體具有工作電壓低、發光輝度高、回應速 度快、壽命長之優點，使其廣泛應用於手機、PDA(個人 數位助理）、顯示器之背光模組中。惟，發光二極體之出 射光具較強之光學指向性，即出射光具有__定之發散角 度’當其直接射人背光模組之導光板時，使得導光板入 光面-側«絲學暗區，且與發光4體相對之位置 易出現光柱，不易獲得較佳之入光均勻度。 [0005] 請參閱圖1與圖2

Description of the Invention: [Technical Leadership of the Invention] [0001] The present invention relates to a light guide plate and a backlight module having the same. [Prior Art] [0002] Since the liquid crystal of the liquid crystal display panel itself has no illuminating property, in order to achieve the display effect, the liquid crystal display panel needs to provide a light source device, such as a backlight module, for the purpose of supplying sufficient brightness to the liquid crystal display panel. A uniform surface light source. [0003] The backlight module of the prior art is mainly composed of a light source, a light guide plate, a reflection plate, a diffusion plate and a seesaw. The light source can be disposed on one side or two opposite sides of the light guide plate and emit a light beam to the light guide plate. The function of the light guide plate is to guide the light beam transmission direction so that the light beam is uniformly emitted from the light exit surface of the light guide plate. The reflector is disposed opposite to the bottom surface of the light guide plate to reflect the light beam emitted from the bottom surface of the light guide plate into the light guide plate to improve the utilization of the light beam. The light-emitting surfaces of the diffusion plate and the gusset plate relative to the light guide plate are sequentially disposed to make the beam distribution from the light guide plate more uniform, thereby improving the brightness and uniformity of the liquid crystal display panel. Just because the light-emitting diode has the advantages of low operating voltage, high luminous brightness, fast response speed and long life, it is widely used in mobile phones, PDAs (personal digital assistants), and backlight modules of displays. However, the outgoing light of the light-emitting diode has a strong optical directivity, that is, the emitted light has a __ fixed divergence angle 'when it directly hits the light guide plate of the backlight module, the light guide plate enters the light surface-side «wire The dark area is studied, and the position of the light body is relatively easy to obtain a uniform light uniformity. [0005] Please refer to FIG. 1 and FIG. 2 09514908^^^^ A〇101 are respectively a plane of the prior art backlight module + page 3 / total 2 page 1013319023-0 1377410 101 years of the revised page of the revised page Schematic and perspective view. The backlight module 10 includes a light source 12 and a light guide plate 13. The light guide plate 13 includes a light incident surface 131, a light exit surface 132 connected to the light incident surface 131, and a bottom surface 133 opposite to the light exit surface 132. The light source 12 is disposed opposite to the light incident surface 131 of the light guide plate 13. The light source 12 is a plurality of light emitting diodes, and the outgoing light beam of the plurality of light emitting diodes enters the light guide plate 13 from the light incident surface 131 of the light guide plate 13 to be guided. Reflection occurs in the light plate 13. The light guide plate 13 guides the light source 12 to emit a light beam, and converts it into planar light to be emitted from the light exit surface 132 of the light guide plate 13. However, since the emitted light of the light-emitting diode has a certain divergence angle, the optical dark area 15 and the light column 16 appear on the light-emitting surface 131 side of the light guide plate 13, and the optical dark area 15 is mainly distributed in two adjacent light-emitting diodes. The position of the light column 16 is opposite to the position of the light guide plate 13 opposite to the light emitting diode, which affects the brightness and uniformity of the light output of the backlight module 10. ' ' " [0006] In view of this, it is necessary to provide a light guide plate that allows light to be uniformly emitted, and a backlight module with uniform luminance. [0007] Hereinafter, a light guide plate that can uniformly emit light by effectively adjusting incident light, and a backlight module having the light guide plate, including a light guide plate, including the light guide plate, include a light-incident surface, a light-emitting surface intersecting the light-incident surface and a bottom surface opposite to the light-emitting surface. The light incident surface includes at least one first groove penetrating the light emitting surface and the bottom surface as a first light receiving region, and at least one second groove penetrating the light emitting surface and the bottom surface as a second light receiving region, the first concave The groove and the second groove are different in shape and alternately arranged on the light incident surface, and each of the first light receiving regions and the second light receiving area are numbered 1 1013319023-0 page 4 / total 20 pages 1377410 On August 21, 101, the correction page receiving area was used to receive light from different light sources. [0009] A backlight module having the above-mentioned light guide plate includes at least two light sources, and a first light receiving region and a second light receiving region of the light incident surface of the light guide plate are respectively provided with a light source. [0010] The light guide plate of the embodiment has the following characteristics: since at least two light receiving regions of different structures are formed on the light incident surface, different guiding and adjusting of light emitted by the same light source can be realized, thereby obtaining different The light emitted from the light guide plate realizes the multifunctional light guiding effect of the light guide plate. [0011] The backlight module having the above-mentioned light guide plate has two kinds of light-emitting characteristics: first, when a light source is disposed separately from the first light-receiving area, the light emitted from the light source enters from the first light-receiving area of the light-incident surface. The light guide plate is derived from the light exiting area corresponding to the first light receiving area on the light emitting surface. Due to the structural characteristics of the first light receiving area and the corresponding light emitting area, the light guided by the light guide plate has certain characteristics, such as a certain brightness. , uniformity, range of viewing angles and other characteristics. When the second light source is disposed separately from the second light receiving region, the light emitted from the light source enters the light guide plate through the second light receiving region of the light incident surface, and is derived from the light exiting region corresponding to the second light receiving region. Due to the structural characteristics of the second light receiving region and the corresponding light emitting region, the light guided by the light guide plate has another characteristic, such as a certain brightness, uniformity, and viewing angle range. [Embodiment] Hereinafter, a light guide plate of the present technical solution and a backlight module having the light guide plate will be specifically described with reference to the accompanying drawings and a plurality of embodiments.
