Description

201126230 VI. Description of the Invention: [Technical Field] The present invention relates to a touch screen and the use thereof, and more particularly to a carbon nanotube-based touch screen. [Prior Art] [0002] In recent years, with the development of high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, electronic devices in which a translucent touch panel is mounted in front of a display device such as a liquid crystal are gradually increasing. . The user of such an electronic device visually confirms the display content of the display device located on the back surface of the touch panel by the touch panel, and presses the touch panel to operate by a finger or a pen. Thereby, various functions of the electronic device can be operated. According to the working principle of the touch screen and the transmission medium, the previous touch screens are generally divided into four types, namely, resistive, capacitive, infrared, and surface acoustic waves. Among them, resistive and capacitive touch screens are the most widely used. The prior resistive touch screen generally comprises an upper substrate, the upper surface of which is formed with an upper transparent conductive layer; the lower substrate, the upper surface of which is formed with a transparent conductive layer; and a plurality of dot spacers (Dot Spacer) It is disposed between the upper transparent conductive layer and the lower transparent conductive layer. The upper substrate is flexible and can be deformed by pressing, so that the upper transparent conductive layer and the lower transparent conductive layer at the pressing place are in contact with each other, and the change of the resistance of the pressing portion is measured by an external circuit, thereby obtaining the coordinates of the pressing portion. Previous capacitive touch screens generally included an insulative substrate, at least a transparent conductive layer formed on the upper surface of the substrate, and a plurality of metal electrodes formed on the edge of the transparent conductive layer. When a touch object such as a finger touches the surface of the touch screen, a coupling capacitor is formed between the touch object and the transparent conductive layer in the touch screen due to the electric field of the human body, 099101716, Form No. A0101, Page 4 / 56 pages 0992003317-0 201126230 The metal electrode and the external circuit sense the coupling capacitance to derive the position of the touch point. In addition, U.S. Patent Application No. US2006/0097991 A1, which is incorporated by reference in its entirety, discloses a point-capacitive touch screen in which a parallel strip-shaped transparent conductive layer is formed on the upper and lower surfaces of the substrate. The strip-shaped transparent conductive layers on the surface are disposed to each other to form a sensing line and a scanning line, thereby realizing multi-point measurement. The transparent conductive layer in the above-mentioned repair and capacitive touch screen is usually made of a layer of indium tin oxide (ΙΤ0). The mechanical and chemical durability of the ΙΤ0 layer is not good, and the 制备 is not bent, and the preparation process is mainly performed by sputtering or evaporation, and the preparation cost is high. [00〇3] Carbon Nanotube (CNT) is a hollow tube made of i τ ® butada graphite film, which has excellent mechanical, thermal and electrical properties, so it has a wide application field. . Since the diameter of a single carbon nanotube is only a few nanometers to several tens of nanometers, it is difficult to process. For practical application, a large number of carbon nanotubes are used as raw materials to form a macrostructure having a large size. The carbon nanotube film (Carbc) ri Nan_ 〇 UtUbe Film, CNT Film) is the specific form of this macro structure. A carbon nanotube film obtained by directly pulling from a carbon nanotube array is disclosed in the Chinese Patent Application No. 200833862, published on Aug. 16, 2008, which has a carbon nanotube film having It is self-supporting on a macro scale and includes a plurality of carbon nanotubes connected end to end under the action of Van der Valli. Since the carbon nanotube film obtained in the direct drawing is substantially parallel to the surface of the carbon nanotube film and there is a gap between the mutually adjacent carbon nanotubes, the carbon nanotube film is more It is transparent. In addition, because the carbon nanotubes in the carbon nanotube film are arranged along the same side of the 099101716 form bat number A〇l01 page 5 / 56 pages 0992003317-0 201126230, the carbon nanotube film can be better. It exerts the conductivity of the nanocarbon_tube axial direction. [0004] [0006] [0006] 099101716 However, in the direct drawing of the obtained carbon nanotube film, adjacent and side by side carbon nanotubes will aggregate contact due to the effect of van der Waals force to form a larger The diameter of the nano carbon_tube bundle, which has a large density, affects the light transmittance of the carbon nanotube film. When used in a touch screen, the transparent conductive layer should be as transparent as possible, and the light transmittance of the touch panel using the above-mentioned carbon nanotube film obtained directly as a transparent conductive layer is still not good enough. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a touch screen having better light transmittance. A touch screen includes: a first electrode plate, the first electrode plate includes a first substrate and a first conductive a layer disposed on a surface of the first substrate; and a second electrode plate spaced apart from the first electrode plate, the second electrode plate including a second substrate and a second conductive layer disposed on the first electrode a surface of the second substrate, the second conductive layer is disposed opposite to the first conductive layer; wherein at least one of the first conductive layer and the second conductive layer comprises a carbon nanotube structure layer, the carbon nanotube The structural layer is composed of a plurality of carbon nanotubes arranged in a preferred orientation along the same direction, the carbon nanotube structure layer having a plurality of thinned regions along the plurality of thinned regions The directions in which the carbon tubes are preferentially oriented are arranged in at least one row. A touch screen comprising: a substrate comprising a first surface and a second surface opposite the first surface; a first conductive layer and a complex form number A0101 page 6 / total 56 pages 0992003317-0 [ 0007] 201126230 Ο [0008]

Compared with the prior art, since the carbon nanotubes are partially scanned by the laser, a portion of the carbon nanotubes are oxidized to form a thinned region, wherein the carbon nanotube distribution density in the thinned region is lowered to make the carbon nanotube film The light transmittance is enhanced, so that the touch panel to which the carbon nanotube film is applied has better light transmittance. [Embodiment] Hereinafter, a touch panel of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 099101716 Form No. 1010101 Page 7 / Total 56 Pages 0992003317-0 [0010] The present invention provides a touch screen having better light transmittance, the touch screen including at least one substrate formed on the surface of the substrate a transparent conductive layer and an electrode electrically connected to the transparent conductive layer. The transparent conductive layer is formed by laying a carbon nanotube film 100 having a good light transmittance on the surface of the substrate. [0012] The preparation method of the carbon nanotube film 100 having better light transmittance comprises the following steps: [0013] Step 1: providing a carbon nanotube primary film 120. [0014] Referring to FIG. 1, the carbon nanotube primary film 120 can be directly drawn from a carbon nanotube array 150, which specifically includes the following steps: [0015] (1) providing a carbon nanotube Array 1 50. [0016] The carbon nanotube array 150 is formed by chemical vapor deposition on a growth substrate surface, preferably a super-sequential carbon nanotube array 150. The carbon nanotube array 150 includes a plurality of carbon nanotubes that are substantially parallel to each other and perpendicular to the surface of the growth substrate. By controlling the growth conditions, the carbon nanotube array 150 contains substantially no impurities such as amorphous carbon or residual catalyst metal particles. The preparation method of the carbon nanotube array 150 can be referred to the Republic of China Patent Application No. 200833862, which was published by Feng Chen et al. on August 16, 2008. [0017] The carbon nanotubes in the carbon nanotube array 150 may include at least one of a single-walled carbon nanotube, a double-walled carbon nanotube, and a multi-walled carbon nanotube. The carbon nanotubes have a diameter of from 1 nm to 50 nm and a length of from 50 nm to 5 mm. In this embodiment, the length of the carbon nanotubes is preferably from 100 micrometers to 900 micrometers. 099101716 Form No. A0101 Page 8 of 56 0992003317-0 201126230 [0018] [0020] [0020]

[0021] It can be understood that the carbon nanotube array 150 provided by the embodiment of the present invention is not limited to being prepared by the above method, and may be a graphite electrode constant current arc discharge deposition method, a laser evaporation deposition method, or the like. (b) The carbon nanotube primary film 120 is obtained by drawing from the carbon nanotube array 150 using a stretching tool 110. Specifically, the method comprises the following steps: (a) selecting a carbon nanotube segment from the carbon nanotube array 150, and in this embodiment, preferably contacting the carbon nanotube array with a tape or a viscous strip having a certain width. 1 50 to select a carbon nanotube segment having a certain width; (b) pulling the selected carbon nanotube segment at a certain speed by moving the stretching tool 110, thereby pulling out the plurality of nano carbons end to end The tube segments, in turn, form a continuous carbon nanotube primary membrane 120. The stretching tool 110 moves substantially in a direction parallel to the surface of the growth substrate. In the above step (2), the carbon nanotube segments selected by the stretching tool 110 may be only one carbon nanotube or may be composed of a plurality of substantially parallel carbon nanotubes. The plurality of carbon nanotubes are arranged side by side such that the carbon nanotube segments have a certain width. When the selected one or more carbon nanotubes are gradually separated from the substrate in the pulling direction under the pulling force, the other carbon nanotubes adjacent to the selected carbon nanotubes are end to end due to the van der Waals force. The cells are successively pulled out in succession to form a continuous, uniform, and wide carbon nanotube primary film 120. Referring to Figure 2, the carbon nanotube primary membrane 120 is a self-supporting structure composed of a plurality of carbon nanotubes. The plurality of carbon nanotubes are arranged in a preferred orientation along the same direction. The preferred orientation means that the majority of the carbon nanotubes in the primary membrane 120 of the carbon nanotubes extend substantially in the same direction. Moreover, the overall extension direction of the majority of the carbon nanotubes is substantially parallel to the surface of the carbon nanotube primary membrane 120. Form number A0101 Page 9 of 56 0992003317-0 201126230. Further, most of the carbon nanotubes in the carbon nanotube primary membrane 120 are connected end to end by van der Waals force. Specifically, each of the majority of the carbon nanotubes extending substantially in the same direction in the carbon nanotube primary membrane 120 and the carbon nanotubes adjacent in the extending direction pass through the van der Waals force. Connected. Of course, there are a few carbon nanotubes in the carbon nanotube film that deviate from the extending direction. These carbon nanotubes do not constitute an overall orientation of most of the carbon nanotubes in the primary membrane of the carbon nanotubes. Significant impact. Further, the carbon nanotube primary film 120 has a certain gap between the adjacent and adjacent carbon nanotubes. The self-supporting carbon nanotube primary film 120 does not require a large-area carrier support, but can maintain a self-membrane state as long as the supporting force is provided on both sides, that is, the carbon nanotube primary film 120 is placed. When (or fixed to) two support bodies disposed at a distance apart, the carbon nanotube primary film 120 located between the two supports can be suspended to maintain its own film state. The self-supporting is mainly manifested by the presence of a continuous carbon nanotube in the primary carbon nanotube 120 of the carbon nanotubes extending end to end through the van der Waals force. Specifically, the majority of the carbon nanotubes in the primary film 120 of the carbon nanotubes are substantially in a straight line shape and may be appropriately bent; or are not completely aligned in the extending direction, and may be appropriately extended. direction. Therefore, it is not possible to exclude partial contact between the carbon nanotubes juxtaposed in the majority of the carbon nanotubes of the carbon nanotube primary membrane 120 extending substantially in the same direction. [0022] Specifically, referring to FIG. 3, each of the carbon nanotube primary membranes 1 20 includes a plurality of continuous and aligned carbon nanotube segments 143. The plurality of carbon nanotube segments 143 are connected end to end by Van der Waals force. Each carbon nanotube segment 143 099101716 Form number A0101 Page 10 / Total 56 page 0992003317-0 201126230 Comprised of a plurality of carbon nanotubes 14 5 parallel to each other, the plurality of carbon nanotubes 145 parallel to each other through Van der Waals The force is closely combined. The carbon nanotube segment 143 has any length, thickness, uniformity, and shape. [0023] The carbon nanotube primary film 120 has a thickness of 0.5 nm to 100 μm, and the length and width are related to the area of the carbon nanotube array 150. 5纳米至10厘米。 The carbon nanotubes of the primary film 120 having a width of about 0. 5 nm ~ 10 cm. The specific surface area of the carbon nanotube primary membrane 120 is greater than 100 square meters per gram. [0024] In the step of selecting and drawing the carbon nanotubes described above, it is difficult to control the thickness of the selected carbon nanotube segments by the stretching tool 110, and the side-by-side carbon nanotubes are easily passed between the van der Waals. The attraction of the force is brought into contact with each other to form a bundle of carbon nanotubes having a large diameter, so that the thickness uniformity of the primary film 120 of the carbon nanotube obtained by the drawing is not good enough. The carbon nanotube bundle contains a large number of carbon nanotubes, so that the density of the carbon nanotube bundle is large, so that the light transmittance is poor, so that the light transmittance of the carbon nanotube primary membrane 120 is not good enough. The carbon nanotube primary film 120 has been tested to have a visible light transmission of at most 75%. [0025] Referring to FIG. 4, the carbon nanotube primary film 120 taken from the carbon nanotube array 150 may be disposed by itself or in a self-supporting suspension, or may be further disposed on a surface of the substrate 140. Specifically, the method includes the following steps: providing a substrate 140; and laying the carbon nanotube primary film 120 on the surface of the substrate 140. Since the carbon nanotube array 150 is very pure in this embodiment, and since the specific surface area of the carbon nanotube itself is very large, the carbon nanotube primary film 120 itself has a strong viscosity. Therefore, the carbon nanotube primary film 120 can be directly fixed to the surface of the substrate 140 by its own adhesiveness. 099101716 Form No. A0101 Page 11/56 Page 0992003317-0 201126230 [0026] [0029] [0029] 099101716. The substrate 140 may be a transparent rigid or flexible substrate, and the material of the substrate 14〇 is not limited. The carbon nanotube primary film 120 can be protected and a certain support can be provided for the nano carbon official primary film 120. The material of the substrate 14 can be glass, quartz, plastic or resin. In this embodiment, the substrate 140 is a polyethylene terephthalate (PET) transparent flat substrate. Further, laying the carbon nanotube primary film 120 on the surface of the substrate 140 may further include the step of coating a surface of the substrate 140 with a layer of adhesive 13 〇. The adhesive layer 130 is uniformly applied to the surface of the substrate 14. The material of the adhesive layer 130 is not limited, and the carbon nanotube primary film 120 may be more firmly bonded to the substrate 140, such as a pressure sensitive adhesive, a heat sensitive adhesive or a photosensitive adhesive. In this embodiment, the material of the adhesive layer 13〇 may be butyl acrylate, 2-ethylhexyl acrylate, vinyl acetate, glycidyl methacrylate, acrylic acid, benzamidine peroxide and toluene, and ethyl acetate. a mixture of esters. Step 1. Using a laser beam 170 to scan the carbon nanotubes in the overall extension direction of the newly escaped most carbon nanotubes, and then scan the local position of the carbon nanotubes in the primary film 120. The plurality of thinned regions 126 are arranged in at least one row in a direction parallel to the preferred orientation of the majority of the carbon nanotubes. It is defined that the overall extension direction of most of the carbon nanotubes is again. The complex thinned region 126 can form a scan line 124 or a plurality of scan lines 124 along the direction_column. The plurality of thinned regions 126 are sequentially formed in the nanocarbon primary film 120 in a certain order. Referring to FIG. 5, when the plurality of thinned regions are arranged in a plurality of rows along the direction X, a laser beam may be first formed in the carbon nanotube primary film 12A along the direction X. The scanning line 124, the scanning line m Form No. A0101 Page 12 of 56 w &quot; 0992003317-0 201126230 Ο [0030] A plurality of thinned regions 126 are included; another scan line 124 is formed in the same manner at a position spaced apart from the scan line 124, and finally A plurality of spaced scan lines 124 are formed in the entire carbon nanotube primary film 120 substantially uniformly in the manner described above. The plurality of scan lines 124 may be arranged at equal intervals or at different intervals, but the scan lines 124 of a certain area should be prevented from being too densely distributed. Preferably, the plurality of scan lines 124 are equally spaced and substantially parallel distributed in the carbon nanotube primary film 120. The pitch d of the adjacent two scanning lines 124 is from 1 micrometer to 5 millimeters, preferably from 10 to 100 micrometers, and is 20 micrometers in this embodiment. In one embodiment, d is much larger than the pitch of the thinned regions 126 in the same scan line 124. Specifically, each of the scanning lines 124 may be formed by sequentially forming a plurality of thinned regions 126 in the direction X. Referring to Figures 5 and 6, the plurality of thinned regions 126 may be spaced apart from each other or arranged in a continuous manner to form an elongated strip region 128. When the plurality of thinned regions 126 are spaced apart, the plurality of thinned regions 126 may be equally spaced from each other. When the plurality of thinned regions 126 are continuously disposed, the plurality of thinned regions 126 in the one scan line 124 may continuously extend from the end of the carbon nanotube primary film 120 to the other end in the direction X. The width D of the scanning line 124, that is, the diameter of the thinned region 126, that is, the strip-shaped region 128 composed of the plurality of thinned regions 126 has a width of 1 micrometer to 5 millimeters, preferably 10 micrometers to 100 micrometers. This embodiment is 20 microns. Preferably, the area of each of the thinned regions 126 is substantially the same, and in the plurality of scan lines 124, the number of thinned regions 126 per scan line 124 is substantially the same. The distribution density of the carbon nanotubes in the thinned region 126 can be reduced or the nanocarbon in the thinned region 126 can be substantially removed by the above-described sequential local thinning of the surface of the entire carbon nanotube primary film 120. Tube, thus reducing 099101716 Form No. A0101 Page 13 / Total 56 Page 0992003317-0 [0031] 201126230 The carbon density of the carbon nanotubes of the carbon nanotube primary membrane 120 is obtained. Tantalum has good light transmission. The mass of the carbon nanotubes in the carbon nanotube film per unit area can be defined as the distribution density. Preferably, the distribution of the carbon nanotubes in the thinned region 126 is not reduced (4) by 5% to 100%, so that the transmittance in the thinned region 126 is increased from 75% to over 85%. The transmittance outside the thinned region 126 is increased by 1% to 2%. The formed carbon nanotube film 1 〇〇 macroscopically remains a film-like structure. Since the thinned region 126 is formed row by row in the direction X and has a certain interval between the adjacent scan lines 124, the carbon nanotube film 1 can be ensured between the adjacent two scan lines 124. The carbon nanotubes having a complete end-to-end connection do not reduce the conductivity of the carbon nanotube film 1 〇〇 in the opposite direction due to the thinning, and the carbon nanotube film 100 is perpendicular to the 兀 direction due to the thinning. Further, the conductivity in the y direction in the carbon nanotube film 100 is remarkably lowered, thereby improving the difference in conductivity between the carbon nanotube film and the y direction. [0035] It can be understood that the step of laying the carbon nanotube primary film 120 on the substrate 14〇 can be performed before or after the second step. The Qinmi carbon tube primary film 120 can be pre-laid on the substrate 140 to be scanned by the laser beam 17〇...... thinning, or can be suspended and scanned by the laser beam 170. The carbon nanotube film 1 having the plurality of thinned regions 126 after thinning can be applied to the surface of the substrate 140 in a stepwise manner. Please refer to FIG. 5 to FIG. 8 together. Step 2 specifically includes the following steps. (1) A laser device 160 is provided, from which the laser beam 170 is emitted to the surface of the primary film 12 of the smectite carbon nanotube to form a spot 18 〇. The laser device 160 can emit a pulsed laser beam 170. The laser beam 17 〇 099101716 Form No. A0101 Page 14 of 56 0992003317-0 201126230 The power is not limited and can range from 1 watt to 100 watts. The laser beam 170 has a good orientation, so that a spot 180 can be formed on the surface of the carbon nanotube primary film 120. The laser beam 170 has a work density density on the surface of the carbon nanotube primary film 120 of greater than 0. 0 53x1 012 watts / square meter. In this embodiment, the laser device 160 is a carbon dioxide laser having a power of ^ 12 watts. It will be appreciated that the laser device 160 can also be selected to be a laser capable of emitting a continuous laser. [0036] The spot 180 is substantially circular and has a diameter of from 1 micrometer to 5 millimeters, preferably 20 micrometers. It will be understood that the spot 180 may be formed by focusing the laser beam 170 or directly irradiating the surface of the carbon nanotube primary film 120 with the laser beam 170. The spot 180 formed by focusing may have a smaller diameter, such as 20 microns. The spot 180 formed by direct irradiation of the laser beam 170 without focusing is of a relatively large diameter, such as 3 mm. [0037] The laser device 160 can also include a plurality of lasers. When the laser device 160 includes a plurality of lasers, the spot may be in the form of a strip or other shape having a width of from 1 micron to 5 mm, preferably 20 microns. [0038] (2) moving the carbon nanotube primary film 120 relative to the laser beam 170, thereby moving the spot 180 along the direction X of the carbon nanotube primary film 120 to form at least one scan line 124. The scan line includes a plurality of thinned regions 12 6 arranged in the direction X. [0039] The spot 180 moves in the direction X in the carbon nanotube primary film 120 to thin the carbon nanotube primary film 120 in the direction X. In order to move the spot 18 0 relative to the carbon nanotube primary film 120, the laser beam 170 can be kept stationary by moving the carbon nanotube primary film 120; or the nano carbon 099101716 can be fixed. Form No. A0101 15 pages / total 56 pages 0992003317-0 201126230 s primary film 120 does not move, by moving the laser beam 17 〇. The laser device 160 can be translated integrally with respect to the carbon nanotube primary film 120, or by changing the light exit angle of the light exit portion of the laser device 16G, the spot 18 formed by the emitted laser beam 170 can be realized in the nanocarbon. The position of the tube primary 臈^ changes. Width 2 with - the plurality of salty thin regions 126 in the scan line 124 can be spaced or continuously set three due to the pulsed laser beam 17 〇 by the complex discontinuous laser pulse group ® laser beam 170 and the carbon nanotube primary The velocity of the film 12 〇 relative movement is large, and the plurality of discrete laser pulses can be irradiated at different positions on the surface of the carbon nanotube primary film 120, thereby realizing a discontinuous portion of the carbon nanotube primary film 120. Thinning 'forms a plurality of discrete circularly thinned regions 126. When the relative movement speed of the laser beam 170 and the carbon nanotube primary film 120 is smaller than the product of the diameter of the spot 180 and the laser pulse frequency (relative motion speed < spot diameter x laser spurt frequency), the complex number is discontinuous The laser pulse irradiation is connected to each other at the position of the surface of the carbon nanotube primary film 120 or overlapped, so that the plurality of thinned regions 126 are distributed continuously. Since the spot moves in the direction X in the carbon nanotube primary film 120, the longitudinal direction direction X of the continuously distributed thinned region 12 6 is parallel. In this embodiment, the distance between two adjacent thinned regions i 26 in the same scanning line is less than j 〇〇 micron 〇 [0041] It can be understood that when a continuous laser is used as the laser beam 17 ,, The switch of the laser is programmed to cooperate with the movement of the carbon nanotube primary membrane 120 to form a spaced or continuous thinned region 12 6 . [0042] It can be understood that since the temperature of the carbon nanotubes is increased and reacted with oxygen after the energy is absorbed, it is only necessary to ensure that the laser of sufficient energy is irradiated in a short time. Page 16/56 pages 099101716 Form No. A0101 201126230 To the surface of the carbon nanotubes, the purpose of thinning the primary membrane of the carbon nanotubes can be achieved. Therefore, it is possible to achieve localized thinning by using laser devices 160 of different power, wavelength or pulse frequency, and correspondingly adjusting the relative motion speed of the laser beam 170 and the carbon nanotube primary film, 120 and the size of the spot 18〇. - The purpose of the carbon nanotube primary membrane 120. It will be understood that the laser device 16 is not limited to a pulsed laser as long as it is capable of emitting a laser to locally thin the carbon nanotube. As shown in Fig. 9, the distribution density of the carbon nanotubes of the thinned region 126 is reduced or the carbon nanotubes of the thinned region 12 6 are all engraved. [0043] Further, a plurality of scanning lines 124 may be formed spaced apart in the carbon nanotube primary film 120. [0044] To form the complex scan line 124, the carbon nanotube primary crucible 120 can be translated a certain distance relative to the laser beam 17〇 in a direction y extending perpendicular to the entirety of the majority of the carbon nanotubes, and then the carbon nanotubes are The primary film 120 is moved relative to the laser beam 170 in a parallel direction x; the laser beam 170 may also be moved a certain distance relative to the carbon nanotube primary film 120 in a direction perpendicular to the direction y 'to make the laser beam 17 〇 in the direction X Relative to the carbon nanotube primary medium 120 movement r In this embodiment, the path of the pupil spot 180 moving on the surface of the carbon nanotube primary membrane I2j) is as shown in FIG. [〇〇45] It can be understood that 'the thin film of the carbon nanotube primary film 110 is thinned by sputtering, in the step (2), the primary film 12 of the carbon nanotube is placed in an oxygen environment, As in the air, carbon in the carbon nanotubes irradiated by the laser beam 170 reacts with oxygen to form carbon dioxide. [0046] In order to remove as much as possible the larger diameter carbon nanotube bundle present in the carbon nanotube primary membrane 120, the laser beam 170 should scan the nanocarbon as uniformly as possible 099101716 Form No. A0101 Page 17 / A total of 56 pages 0992003317-0 201126230 The entire surface of the primary film 12G, thereby forming a plurality of uniform and spaced scan lines 24 on the surface of the carbon nanotube primary film i2. [0050] [0050] Since the carbon nanotube has good absorption characteristics for the laser, the carbon nanotube bundle having a larger diameter in the carbon nanotube primary membrane 120 will absorb more The heat 'and thus the secret removal' greatly increases the transparency of the formed nanocarbon. The light transmittance of the entire carbon nanotube film 1 in the present embodiment may be more than 75%. Preferably, the light transmittance of the nanotube film 1 is 95%. Referring to FIG. 10, since in step (2), the spot 18 is moved along the direction X in the primary film 120 of the carbon nanotube, so that the laser beam 17 is along the majority of the carbon nanotube primary film 120. The carbon nanotubes are integrally extended to reduce the carbon nanotube bundle. Therefore, when one scan line 124 of the carbon nanotube primary film 120 is thinned, it is necessary to thin the next scan line 124 without having to make two scan lines 124. The thinned regions 126 are aligned in the y-direction. As shown in FIG. 10, when the spot 18 is moved in the direction X of the carbon nanotube primary film 12, even if the thinned regions 126 in the two scanning lines I24 are staggered, the two scanning lines 124 are not affected. Nailai carbon tube 145. Therefore, the formed carbon nanotube film 1 奈 between the two adjacent scanning lines 124 of the carbon nanotube 145 can remain intact and end-to-end without damage, so that the carbon nanotube film 100 is The conductivity in the direction X is not affected. It will be appreciated that the advantage of thinning in the direction X is particularly pronounced when the thinned regions 126 are continuous. Referring to the figure, when the continuous thinned region 126 is formed along the direction X, the carbon nanotubes 145 between the adjacent two scanning lines 124 are not thinned, thereby making the carbon nanotube film 1〇〇 The conductivity in the direction X 099101716 Form No. A0101 Page 18 / Total 56 pages 0992003317-0 201126230 and the strength is basically unaffected; the carbon nanotubes 145 connected in the direction X between the adjacent two scanning lines will not be cut. The electrical conductivity and strength of the carbon nanotube film 100 in the direction X are prevented from being greatly reduced. [0051] In order to remove the carbon nanotube bundle in the carbon nanotube primary film 120 as much as possible, the spacing between the adjacent two scanning lines 124 is not too large, so as not to affect the conductivity of the carbon nanotube film 100. Sex, the spacing between the adjacent two scanning lines 124 should not be too small. Preferably, the spacing between the two adjacent scanning lines 124 is from 1 micron to 5 mm, preferably 20 microns. 005 Ο [0052] It can be understood that the carbon nanotube film 100 obtained by laser thinning is still a self-supporting film-like structure, and the light transmittance is improved after thinning, and is performed in the direction X. When the thickness is reduced, the conductivity of the carbon nanotube film 100 in the direction X is maintained to some extent, and the conductivity in the direction y is lowered, so that the carbon nanotube film 100 has good anisotropy.

The carbon nanotube film 100 can be bonded to the substrate 14 by its own viscosity. Or by bonding the substrate 140 to the substrate 140. [0056] [0059] In addition, the substrate 140 can be The surface is first coated with an insulating polymer material/grain solution. The carbon nanotube film is covered with the polymer solution, and the carbon nanotube film 100 is embedded in the polymer solution to make the polymer solution. Curing, thereby forming a composite film. The cured polymer material can function as the binder layer 130. In addition, since the polymer material blocks the contact between the gamma-direction carbon nanotubes, the composite film is more than a single nanometer. The anisotropy of the carbon nanotube film is further improved. Referring to Figures 5, 6, 10 and 11, the carbon nanotube film 100 having better light transmittance is composed of a plurality of carbon nanotubes, The carbon nanotubes are arranged in a preferred orientation along the same direction, and the plurality of thinned regions 126 and the non-thinned regions outside the thinned regions 126 are defined in the manifold film.

The carbon nanotube film 1〇〇 may include a plurality of mutually spaced intervals Scan line 124, the complex scan line 124 is The carbon nanotube film 100 is formed by the carbon nanotube primary film 12〇 having substantially the same microstructure as the carbon nanotube primary film 12〇, however, the carbon nanotube film 100 further defines a plurality Thinning area 126. The plural number minus the domain 1 26 can be distributed in the non-thinning area 099101716 Form number Α 0101 Page 20 / Total 56 page 0992003317-0 201126230 Ο [0060]

Or distributed in the non-thinned area in a staggered manner. Specifically, the scan lines 124 are all parallel to the direction X, the plurality of thinned regions 12.6 in the same scan line 124 are substantially aligned in the direction X, and the thinned regions 126 of the plurality of scan lines 124 are aligned or misaligned in the direction y Quasi-interlaced settings.

The plurality of thinned regions 126 arranged in a plurality of rows are arranged parallel to each other and at equal intervals. The plurality of thinned regions 126 of the same scan line 124 may be spaced or continuously set. The plurality of thinned regions 126 of the same scan line 124 may be further spaced from one another, preferably less than 100 microns apart. The length direction of the thinned region 126 of the succession setting is parallel to the direction X. The plurality of thinned regions 126 preferably have substantially the same area. Each of the scan lines 124 preferably has substantially the same number of thinned regions 126. The thinned region 126 is formed by heating and oxidizing the carbon nanotube by means of laser irradiation. The thinned region 126 has a relatively rare carbon nanotube, and the distribution density of the carbon nanotube in the thinned region 126 may be less than 50% of the distribution density of the non-thinned region carbon nanotube, thereby making the reduction The visible light transmittance of the thin region 126 is increased from about 75% to 85% or more, and is higher than the visible light transmittance of the non-thinned region by 10% or more. The laser scanning is along the overall extension direction of the carbon nanotubes, so that the partial carbon nanotube primary film 120 between the two adjacent scanning lines 124 is not destroyed, so that the carbon nanotube film 100 is in the nanocarbon. The conductivity in the direction in which the tube extends is good, and the anisotropy of the carbon nanotube film 100 is improved. In addition, it can be understood that before using the laser scanning carbon nanotube primary film 120, the plurality of carbon nanotubes primary 099101716 form number A0101 page 21 / 56 pages 0992003317-0 201126230 film 120 can be stacked on each other to form a film 120.
