[Embodiment] [First Embodiment] A schematic sectional view of an optical sensing module according to a first embodiment of the present invention. Referring to m, the optical sensing module of the present embodiment and (8) the conductive member no, the light source 120, the shading member 130, the plurality of photo sensors 14A, and the optical element iso. The light-conducting member 110 has a light-incident surface and a light-emitting surface 110b, and has an angle of 0 between the light-incident surface 110a and the light-emitting surface 11b. In detail, the incident surface 11 can be connected to the light-emitting surface 11b, and the incident surface li〇a and the light-emitting surface 110b have an angle of 0, and the angle θ is, for example, 9〇〇. However, the present invention is not limited thereto, and the angle 入 between the light incident surface 110a and the light exit surface u〇b can be differently designed according to actual needs. The Lu light conducting member 110 further has an optical surface 11 〇c, and the optical surface 11〇c is opposite to the light emitting surface 110b. The light conducting member 110 can further have a plurality of optical microstructures 112 that are located on the optical surface 11〇c. These optical microstructures 112 can include a plurality of V-shaped grooves or a plurality of scattering dots. These V-shaped grooves or scattering dots allow the light l emitted from the light source 120 to be uniformly emitted from the light-emitting surface 110b. In this embodiment, the material of the light-conducting member HQ may be polymethyl methacrylate (PMMA), polycarbonate (PC), or ethylene terephthalate (p〇iyethylene terephthalate). , PET) or glass, but the invention is not limited thereto. 201224542 ~ i34 36142tw£doc/t The escape is suitable for providing light l, and the light l is emitted from the light incident surface n〇a 4 U〇 and exits the light guide 110 from the light exit surface UOb. After the human light surface 110a enters the light-conducting member 110, the wind can be transmitted through the optical microstructure 112j5_|+5 Φ. The Fu reflection is emitted to the first surface 110b. In this embodiment, light source 120 includes a source of non-visible light. For example, the light source 120 is, for example, an infrared ray light emitting diode (IR led), but the invention is not limited thereto. ▲, the component 130 covers a partial area of the light surface 11〇b. For example, the light-shielding element 130 may include a plurality of arrays of light-shielding patterns 132 and light-emitting openings H defined by the light-shielding patterns 丨32, and the light-shielding patterns <132 and the light-emitting openings H are along the row direction and the columns. The light-shielding pattern 132 and the light-emitting opening H arranged in the same row are alternately arranged along the column direction, and the light-shielding pattern 132 and the light-emitting opening 排列 arranged in the same row are alternately arranged along the row direction, in other words, the light-shielding pattern 132 and the light-emitting opening Η are alternately arranged to form a checkerboard shape, for example, as shown in FIG. 2. However, the present invention is not limited thereto. In other embodiments, the light shielding member 130 may also be one or more light shielding plates having a plurality of openings, and the aforementioned openings are, for example, uniformly distributed in the light shielding plate. It is worth mentioning that the light l emitted by the light source 120 is not completely blocked by the light shielding member 130, that is, the light 1 can still be emitted from the light exiting surface 11b through the light exit opening η, and is used for sensing. In the present embodiment, the light shielding member 130 is, for example, a reflective layer or a light absorbing layer, and the material of the light shielding member is preferably a material capable of reflecting or absorbing light, such as a metal, a white sheet or a light absorbing resin. The plurality of photo sensors 140 are disposed on the shading element 130. For example, 201224542 AU1007134 36142twf.doc/t', each of the photo sensors 140 can be disposed on each of the shading patterns 132. In other words, the light exit opening 定义 defined by the light shielding pattern 132 is distributed between the light sensors 140. It is worth mentioning that the optical sensor 140 can be integrated on the light-conducting member 110 through the above-mentioned arrangement, so that the optical sensing module 1 of the embodiment can be effectively thinned. The optical element 150 is disposed above the light-emitting surface 110b, wherein the light sensor 140 and the light-shielding element 130 are located between the optical element 15A and the light-conducting member 11?. The optical element 150 has a touch surface 100d. The light L passes through the optical element 15〇 after leaving the light-transmitting surface 110b from the light-emitting surface 110b. When the object F touches the touch surface l〇〇d, the light L is reflected by the object. It is received by the photo sensor 140. For example, the optical element 150 may be a micro-lens array substrate 152 having a touch surface 100d and a microlens surface S opposite to the touch surface i〇〇d, and micro The lens surface S faces the light exit surface ii 〇 b. In this way, after the light L exits the light guiding member 11 from the light emitting surface 110b, the light 1 can effectively converge to the plurality of focal points P through the plurality of microlenses in the micro mirror array substrate, and the focus P is located in the touch. ^ Surface 1 〇〇d. Thus, when the object F touches the touch surface l〇〇d, the light beam L'' reflected by a certain touch point A on the object F has a small degree of divergence. In other words, the light L' reflected by a certain touch point A on the object F can be accurately projected onto the light sensor 140 around the touch point A', thereby making the optical sensing module 100 of the embodiment The shape, moving direction and position of the object F are accurately sensed. In other embodiments, the optical element 15 can include a microlens array substrate 152 and a cover 154. The cover plate 54 has a touch surface 1〇〇d, and the micro-lens array substrate 152 is disposed between the cover plate 154 and the light-conducting member no. The micro-lens array substrate 152 has a micro-lens array substrate 152 having a touch surface 1〇〇d, a micro-transparent 201224542 ^uiv/u/134 36142 twf. The microlens surface S, and the microlens surface S is facing the cover 154, for example as shown in FIG. It is to be noted that the position of the touch surface 100d of the cover 152 is, for example, on the focal plane of the microlens array substrate 152. In this way, the light 1 can be focused on the touch surface after passing through the microlens array substrate 152. In this way, when the object F touches the touch surface i〇〇d, the light L' reflected from a certain touch point A on the object f can be more accurately projected to the light around the touch point a. On the detector 140, the sensing sensitivity and accuracy of the optical sensing module 100 are further improved. Of course, the optical element 150 can also include a collimating lens 156, such as shown in Figures 4A and 4B. The function of the collimated lens 156 is similar to that of the microlens array substrate 152. It should be specially noted that 'when the optical microstructure H2 and the photo sensor 14 are not overlapped (for example, as shown in FIG. 4B), the collimating lens 156 can collect the light L reflected from the optical microstructure 112 onto the touch surface. The optical sensing module 100 of the present embodiment smoothly performs the sensing operation. The optical sensing module 本 of the present embodiment can be further integrated in the display panel 200. In detail, the light-transmitting member 11A of the present embodiment may be the color filter substrate c in the display panel 200 as shown in Fig. 5A. Of course, in other embodiments, the active device array substrate T in the display panel 2 can also be selected as the light conducting member 11A as shown in the drawing. It is worth mentioning that if the active device array substrate τ is used as the light conducting member 11 (), the microlens array 15 2 can be further fabricated with the partial color filter substrate C and used as 201224542 AU1007134 36142twf.doc/t Used for optical component 150. In this way, the display panel 200 using the optical sensing module j can be optimized in thickness and volume. [Second Embodiment] Fig. 6 is a cross-sectional view showing an optical sensing module 3 according to a second embodiment of the present invention. The optical sensing module 300 of the present embodiment is similar to the optical sensing module 100 of the first embodiment. The following only describes the differences between the two, and the same 0 will not be repeated. Referring to the figure, the optical sensing module 3 of the present embodiment includes a light guiding member 110, a light source 120, a light blocking member 130, a plurality of photo sensors 14A, and an optical member 150. The light-conducting member 110 has a light-incident surface u〇a and a light-emitting surface 110b, and has an angle of 0 between the light-incident surface li〇a and the light-emitting surface u〇b. The light source 120 is adapted to provide light 1, and the light 1 enters the light guiding member 110 from the light incident surface ii〇a and exits the light conducting member 11A from the light emitting surface 110b. The light shielding member 130 is disposed on a partial region of the light exit surface ii 〇 b. A plurality of photo sensors 14A are disposed on the shading element 130. The optical element 15A is disposed above the light-emitting surface n〇b•, wherein the light sensor 14〇 and the light-shielding element 130 are located between the optical element 150 and the light-conducting element 11〇, and the optical element has a touch surface 1〇〇d, The light L passes through the optical element 150' after exiting the light-transmitting surface 11 from the light-emitting surface i10b. When the object F touches the touch surface 1 (1, the light [is reflected and received by the light sensor 140. It is noted that, in this embodiment, when the light L emitted from the light source 12 is separated from the light exit surface U〇b, the divergence angle α is lower than 4 degrees, and the optical element 15 of the embodiment is, for example, a cover. The plate 154, and the cover plate 154 has a touch surface 103d. In detail, since the light source 12A of the present embodiment refers to the 201224542 *34 36142twf.doc/directionality light source, and the embodiment The optical microstructure 112 has a special angular design 'so that the light L can exit the light exit surface 1 l〇b with a small divergence angle α (a relatively uniform direction), thus even without the microlens array substrate 152 being disposed. When the object F touches the touch surface 1〇〇d, 'by the object F The touch point A reflects the light L, and can still be accurately projected on the corresponding light sensor 140, so that the optical sensing module 300 of the embodiment can be correctly sensed without passing through the microlens array substrate 152. The shape, moving direction and position of the object F. For example, when the thickness D of the cover plate 154 is 0.1 cm and the hand fingerprint path gap κ is smaller than 〇1 cm, the light beam L is divergent angle α when it exits from the light exit surface ii〇b. The optical sensing module 3 can be used for better sensing. However, the present invention is not limited thereto, and the divergence angle α can also be seen by the thickness D of the cover 154 and the fingerprint path of the hand. The size of the gap κ is appropriately designed. The optical microstructure 112 of the present embodiment has a special design. The optical microstructure 112 of the present embodiment is, for example, a ν-shaped groove having a first surface S1 and a second surface. The surface S2, the first surface S1 is connected to the second surface s2 to form a v-shaped groove, wherein the first surface S1 and the optical surface u〇c have an angle of 6»b, the first surface S2 and the optical surface u〇c are angled When the light ^ only enters the light-emitting surface 11〇 into the light-emitting surface 11〇 El is better between 1〇~1〇〇' and the angle is better than ^2~45〇, and the 'light L' is from the entrance surface n〇a and The smooth surface u〇a = the other light-input surface U〇a, the angle of the light-conducting member 11〇 is preferably less than 35°, and the angle Θ2 is preferably less than 50〇. s 12 201224542 AU1007134 36142twf The .d〇c/t sensing module can be effectively thinned. In addition, although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art, The scope of the present invention is defined by the scope of the appended claims.
