When the optical sensing position is the influence of the Ι 位 position, the tamping microspheres 116 in the target micro-(4) can use the light-transmitting or semi-transmissive material to make 2 particles, glass granules or liquid droplets. In this embodiment, at least a portion of the outer surface of ^ ^ is coated with a conductive material. When the target bead is in its initial position, the first electrode ιΐ8Α and the first electrode 118Β are electrically connected to each other through the target bead. Further, the unit 118 can determine whether the target microbead is in its initial position by both the first electrode η8 Α and the second electrode 1 brain being turned on. For other actual wipes according to the present invention, the conductive material on the surface of the coated (four) or the like bead 116 may also be replaced by a dielectric material. When the microbeads m surface system is coated with a dielectric material, the sensing unit m can determine whether the target microbead is in its initial position by detecting a change in capacitance between the first electrode (10) eight and the second electrode 118B. Light source 100A is used to provide a light beam. In practice, the beam can be near-infrared (wavelength 768mn, 980nm or 1064nm), krypton laser, 632 legs or 633nm, green light (wavelength is Congcon or current coffee) or blue ( Wavelength 488 nm). As shown in Fig. 1(A), the beam passes through the lens 1〇〇B and is then focused on the outside of the pointing device 100 (ie, the dotted line meets, and the surrounding 19IS (10) particles are locally controlled by the laser light ^ == The laser beam and the lens can reach = as shown in Fig. - (8), when the user manipulates the pointing device to touch the near sensing device and rotates the light into the ankle ❹ sensing region, the target bead will move toward The optical tongs "moves away from their initial position. At this time, the first electrode 118A and the target microbeads are no longer conductive to each other; the sensation scale m can be transposed accordingly" to point to the induction corresponding to the target microbead Or, if the surface of the target bead is coated with a dielectric material, = the optical device is deviated, and the capacitance between the first electrode: the electrode 118Β will also change. The two-electrode device 100疋 No pointing to the sensing area corresponding to the target bead. The sensing unit 118 can also simply indicate the location of the device by the change of the capacitance value between the electrodes of the other electrodes between the other electrodes: to correspond to other microbeads Sensing area. The effect of using the touch device (10) to reach the specific position of the panel is not to be pressed. In another embodiment, the electrode included in the sensing unit 118 is shown as being Provided on the upper substrate 112. Without being subjected to 暮, s = two inches, the second electrode 118C and the fourth electrode 118D are not electrically affected by the pointing device 100 and moved between the third and fourth electrodes U8D. The third electrode 118C and the fourth electrode 9 200945139 f 118D will pass through the target beading unit 118 and can be judged by the external measurement of the flute two buds = 〇 = == The fourth electrode _ whether or not the device 100 is in its initial position, thereby determining that the indication forest is directed to the sensing region corresponding to the target microbead. The electrode included in the coffee sensor unit 118 can also be as shown in FIG. 1(E) and FIG. _不'—the part is set to = placed on the lower substrate 114. When the 兮曰 Sa Pei and the 4 knives are set to the pole salt and the second electrode ^ position, the first - electric Ο 睪 睪 plastic and received; When the target bead is subjected to = and is moved between the second electrode 118c and the fourth electrode mD, mD will be connected to each other. In this case, the sense of f can be as early as the same as the above-mentioned suspicion of the above-mentioned electric condition to the lining device KK) fine money device 11G _ _ _ _ _ _ _ _ _ _ _ _ _ _ The direction of the pliers_offset is not limited to the direction of the money. In this example, when the optical bead is affected, after the bead 116 is in its initial position, the bead 116 can be shifted in the horizontal direction. In particular, Figure 4 (A) and Figure 4 (B) illustrate two other examples according to the present invention. In both examples, the surfaces of the beads 116 are coated with a full shot or a full absorption of the element. The material of the light provided by source 100A. According to the theory of light and & attached, when the beam provided by the light source 100A is totally reflected by the bead, the focused beam will instead form a thrust on the bead instead of the suction, as shown in Figure 4(A). In the example, after being subjected to the light beam provided by the light source 100A, the beads 116 are pushed away from their initial positions from left to right. In the example of Figure 4(B), the bead 116 affected by the beam is pushed from top to bottom = initial position. On the other hand, as shown in Fig. 5(A) and Fig. 5(B), when a microbead is located at its initial position, the external light is reflected by the bead 116 and is reflected as - 10 200945139 when the microbead 116 deviates from its initial position, and the light path of the outer light path through the micro-light path will cause different viewers, and this difference can be further used to provide a trace according to the present invention. The effect of the town should be installed after the detection of the situation: for example, when the sensing unit ns ❹ ❹ control unit = 2 = Tian 5 beads have deviated from their initial position. Then, the square optical _ force scale electric force, etc. _ such as five seconds) continue to deviate from its initial state: i: state single brother 'after knowing that the target microbeads deviate from their initial position, the platoon Ϊ́ίΐίΐϊ!: The same characteristics, so that the target bead is opposite to the two electrodes = ^ position 嶋. In contrast, if the second electrode is to be controlled, the first electrode 118 is controlled early, and the bead is subjected to a fine reversal of the electric surface, so that the target micro-===== indicates that the device can be kept away from the initial position. The state of the second and the fifth = the effect of the cooperation and the sacrificial (four) hemp, 11 200945139 Please refer to FIG. 6 (Α), and FIG. 6 is a schematic diagram of the optical sensing system 2 according to the second embodiment of the present invention. The greatest difference between this embodiment and the embodiment shown in Fig. 1 (在于) is that the light source provided by the pointing device 2 is substantially parallel light, and the substrate 212 above the sensing device 210 is provided with a plurality of microlenses 22 〇. As shown in FIG. 6(Α), each of the microlenses 22 〇 corresponds to a microbead 216. ❹ ❹ As shown in Fig. 6 (Β), when the pointing device 200 is moved to the vicinity by the user, the position f of the device 210, the light beam emitted by the pointing device will pass through the two microlenses 220. The focused light passing through the microlenses 22 可 can be clamped to the shape of the sensing device 21G _ (i.e., where the dotted line in Fig. 6 (8) meets). When the optical clamp is inserted into the sensing region of the target microbead, the target microbead will move (4) from the initial position of the lower electrode 214 to the second electrode 218A and the second electrode 2 The target beads are no longer conductive to each other because of the deviation of the target beads; the sensing unit 218 determines that the pointing device 2GG is directed to the sensing region corresponding to the target bead. Or 'the surface of the microbeads 216 is coated with a dielectric ΐ, the target microbeads are deviated by the optical W effect, and the sensing unit 218 "changes the capacitance between the first electrode 218 债 and the second electrode 218 债__The sensing area of the target bead. The guiding ΐΐιίΐΠΓ8 can also judge whether the indication is directed to the sensing area corresponding to the other microbeads by the conduction/non-V-pass or other inter-electrode capacitance values between the other electrodes. ^ 疋The same as the previous embodiments, the user also sets the effect. In the present, the sensing device 21 is connected to the control unit 230. The f 200 step of the control unit 23G is used in conjunction with the relevant application of the tablet. ^ 12 200945139 Please refer to FIG. 7(A), and FIG. 7(A) is a schematic diagram showing the optical sensing device 3 according to the third embodiment of the present invention. As shown in FIG. 7(A), the optical sensing device 3 A light source 300, a plurality of microbeads 316, a plurality of microlenses 320, an upper substrate 312, a lower substrate 314, and a sensing unit 318 are included. As shown in FIG. 7(A), the microbeads 316 are arranged in an orderly manner. On the upper substrate 312 and the lower substrate 314 Each of the microlenses 32 corresponds to one of the microbeads 316. The light source 300 is disposed under the lower substrate 314 and emits light upward. In this embodiment, the microbeads 316, the upper substrate 312, the lower substrate 314, and The plurality of electrodes disposed on the lower substrate 314 are made of a light-transmitting material, so that light emitted from the light source ❹ 300 can penetrate the components and be transmitted to the outside of the optical sensing device 3. As shown in Figure 7 (A) from the left For example, the fourth microbead 316 (target microbead) and the micro ray 32 〇 (hereinafter referred to as the target microlens) corresponding to the target microbead are taken as an example, and the first electrode 318A and the second electrode 3 should be respectively It is disposed on both sides of the target microbead.
