accumulates in the encapsulant layer, which in turn affects the optical performance and the service life of the luminescent wafer, so that the encapsulant layer 2124 of this embodiment is Fluorescent powder was not implanted. The light guide plate 2200 is disposed beside the light emitting diode unit 2100, and has a light incident surface 2210, wherein the light incident surface 2210 faces the light emitting diode unit 2100, and the light emitted by the light emitting chip 2122 of the light emitting diode unit 2100 is emitted from The light incident surface 2210 enters the light guide plate 2200. The light wave conversion element 23 is disposed between the light guide plate 2200 and the light emitting diode unit 2100. The light wave conversion element 2300 has a plurality of grooves 2310, and the grooves 2310 对应 correspond to the cover light emitting diodes 2120. The material of the lightwave conversion element 2300 is mainly a phosphor powder, and in order to enhance the intensity of the light wave conversion element 2300, when the light wave conversion element 2300 is formed, the fluorescent powder having a good concentration is added to the silicone or the epoxy. The resin (Epoxy) is post-formed. The phosphor used to form the lightwave converting element 2300 is selected in accordance with the properties of the light emitting diode 2120. For example, in order to emit white light, when the light-emitting diode 2120 is selected as the blue light-emitting diode, the material of the light-wave converting element 2300 is yellow light-emitting powder. When the blue light emitted by the blue light emitting diode is projected to the light wave converting element 2300 made of the yellow fluorescent powder, the yellow fluorescent powder is excited to emit yellow light, and is mixed with the blue light emitted by the light emitting diode 2120 into white light. . In another embodiment, the light-emitting diode 2120 is a UV light emitting diode, and the material of the light-wave converting component 2300 is selected from a red fluorescent powder, a green fluorescent powder, and a blue fluorescent light. Light powder. Similarly, the light emitted by the ultraviolet light emitting diode is projected to the light wave conversion element 2300 made of red light fluorescent powder, green fluorescent powder, and blue light fluorescent powder 12 1 ^OZlTW 26697twf.doc/n 201044067 light powder. When the light wave conversion element 2300 is excited by red, green, and blue light, the three kinds of light are mixed to emit white light. 〇❹ As described above, the recess 231 光 of the light-wave converting element 23 〇 corresponds to the cover light-emitting diode 2120, and the light emitted from the light-emitting diode 2120 is irradiated to the light-wave converting element 2300, and the light-wave converting element is excited. The phosphors in the 23 Å illuminate and illuminate each other to excite more different wavelengths of light. Compared with the conventional one, since no matter or object in the light wave conversion element 2300 restricts the traveling angle of the light, the light of the light-emitting diode unit 2100 can be converted into a relatively uniform surface light source by the light wave conversion element magic (8). . Therefore, compared with the conventional one, the light entering from the light-wave converting element 23 and entering the light-guiding plate 22 from the light-incident surface 2210 of the light guide plate 2200 has a large angle of entry angle, so that the conventional backlight module can be improved. The light guide plate has the disadvantage of jetting bright lines. In addition, the distance between the light-emitting diode 2120 and the light guide plate 2200 can be increased by the light-wave converting element 23, and the deformation of the light-emitting diode 22g can be avoided, thereby prolonging the use of the backlight. In view of the above, since the wavelength range of the light-emitting diode survey affects the overall optical performance of the back $: 20: and in order to make the backlight module 2_and the light=now', it usually limits the use of the backlight module. The wavelength range of the polar body (10) is different from that of the light-emitting diodes 2m_2 of the light-emitting diode 2m_122_t, and the wavelengths emitted by the light-emitting diodes of the earth and earth are not uniform. Therefore, in order to reduce the light-emitting wavelength range of 201044067 ru / υ i 〇wi-1TW 26697twf.doc/n one body 2120, the number of light-emitting diodes that can be selected on the same wafer is small, and the cost of the light-emitting diode 2120 Relative increase. In addition, 'the characteristics of the light-emitting diode 2120 and the light-wave converting element 23' can also provide a way to greatly save the manufacturing cost of the backlight module. 3A is a sound diagram of a light-emitting diode and a light wave conversion element, and FIG. 3B is a color diagram of the light-emitting diode of FIG. 3A and the corresponding light wave conversion element in a CIE 1931 chromaticity diagram. schematic diagram. Referring to FIG. 3A and FIG. 3B simultaneously, the backlight module 2000 can have a uniform chromaticity performance by the wavelength range of different illuminating wafers corresponding to different illuminating wavelength ranges of the luminescent powder. In detail, the substrate 2η〇 can be at least divided into a first region 2110a and a first region 2110b′, and the light emitting diode 2120 includes a plurality of first light emitting diodes 2120a and a plurality of second light emitting diodes 2120b, wherein The light-emitting wavelength range of the first light-emitting diode 2120a corresponds to A in FIG. 3B, and the light-emitting wavelength range of the second light-emitting diode 2120b corresponds to B' in FIG. 3B and the first light-emitting diode 2120a is correspondingly disposed on the first light-emitting diode 2120a. In the region 2110a, the second light-emitting diode 2120b is disposed in the first region 2110b. Correspondingly, the lightwave converting element 2300 includes at least a first lightwave converting component 2300a and a second lightwave converting component 2300b, wherein the concentration of the phosphor powder by forming the first lightwave converting component 2300a and the second lightwave converting component 23〇〇b Alternatively, the light transmitted through the first light wave conversion element 2300a and the second light wave conversion element 2300b may have different chromaticities. In the present embodiment, the wavelength of light transmitted through the first lightwave converting element 2300a is 14 OZ1TW 26697twf.doc/n 201044067 JL \JI \J dk is PI, and the wavelength of light transmitted through the second optical wave converting element 2300b is P2. The first light wave conversion element 2300a is disposed corresponding to the first light-emitting diode 2120a in the first region 2110a, and the second light wave conversion element 2300b is disposed corresponding to the second light-emitting diode 2120b in the first region 2110b. As shown in FIG. 3B, when the light emitted by the first light-emitting diode 2120a in the first region 2110a passes through the first light-wave converting element 2300a, the light L1 emitted from the first light-emitting diode 2120a will have A and P1 in the CIE 1931 chromaticity diagram of FIG. 3B. Chromatic performance on the line. It is worth noting that by adjusting the concentration component of the first lightwave converting element 2300a, the chromaticity of the light L1 can be expressed in the CIE 1931 chromaticity diagram as approaching A or approaching P1. When the light emitted by the second light-emitting diode 2120b in the first region 2110b passes through the second light-wave converting element 23〇〇b, the light L2′ emitted by the second light-emitting diode 2120b is connected to B and P2 in the chromaticity diagram of FIG. 3BiCIE 1931. Chromatic performance. Similarly, by adjusting the density component of the second lightwave converting element 2300b, the chromaticity of the light L2 can be expressed in the ciE 1931 chromaticity diagram as approaching B or approaching P2. As can be seen from the above, in order to achieve uniform chromaticity performance of the backlight module 2000, the components and concentrations of the phosphors forming the first lightwave conversion element 2300a and the second lightwave conversion element 23〇〇b can be selected first. The wavelength range of the corresponding first light-emitting diode 2120a and the second light-emitting diode 212〇b is selected by using the CIE 1931 chromaticity diagram. Alternatively, the first light-emitting diode 212〇a and the second light-emitting diode 21 may be selected first, and the first-wavelength conversion element 2300a and the second light-wave conversion element 23%% may be selected correspondingly. The composition and concentration of the fluorescent powder. In this way, not only the composition and concentration of the phosphor powder can be selected according to the wavelength range of the light-emitting diode 15 2010440671TW 26697twf.doc/n 2120, and the light-emitting diodes fabricated on the same wafer can be selected. The wavelength range is relatively large, so that the manufacturing cost of the backlight module 2000 can be effectively saved. Then, referring to FIG. 2, in order to fix the relative position between the lightwave conversion element 2300 and the light guide plate 2200 and the light emitting diode unit 21, the light wave conversion element 23 is clamped in this embodiment. 〇 fixed. In detail, the backlight module 2 further includes at least one fixing member 2400, and the fixing member 2400 is, for example, a cassette.
