触摸式液晶屏的制备方法 The method of preparation of the LCD touch screen

技术领域 FIELD

[0001] 本发明涉及一种液晶屏的制备方法,尤其涉及一种基于碳纳米管的触摸式液晶屏的制备方法。 [0001] The present invention relates to a method for preparing the liquid crystal panel, and particularly to a method for preparing a carbon nanotube based touch-screen LCD.

背景技术 Background technique

[0002] 液晶显示因为低功耗、小型化及高质量的显示效果,成为最佳的显示方式之一。 [0002] The liquid crystal display because of low power consumption, miniaturization and high-quality display, one of the best display mode. 目前较为常用的液晶显示屏为TN(扭曲向列相)模式的液晶显示屏(TN-IXD)。 Now more commonly used as a TN liquid crystal display LCD (twisted nematic) mode (TN-IXD). 对于TN-IXD, 当电极上未施加电压时,液晶显示屏处于“OFF”状态,光能透过液晶显示屏呈通光状态;当在电极上施加一定电压时,液晶显示屏处于“ON”态,液晶分子长轴方向沿电场方向排列,光不能透过液晶显示屏,故呈遮光状态。 For TN-IXD, when no voltage is applied to the electrodes, the LCD is in "OFF" state, light was transmitted through the LCD light passing state; when a constant voltage is applied to the electrodes, the liquid crystal display screen is "ON" state, the long axis direction of the liquid crystal molecules are aligned in the direction of the electric field, the light can not pass through the liquid crystal display, it is made a shielding state. 通过有选择地在电极上施加电压,可以显示出不同的图案。 By selectively applying a voltage to the electrode, it may exhibit different patterns.

[0003] 近年来,伴随着移动电话与触摸导航系统等各种电子设备的高性能化和多样化的发展,在液晶等显示元件的前面安装透光性的触摸屏的电子设备逐步增加。 [0003] In recent years, along with development of high performance and diversification of electronic devices of various mobile phones, car navigation systems, such as liquid crystal display increases progressively in front of the electronic apparatus mounting element translucent touch screen. 这样的电子设备的使用者通过触摸屏,一边对位于触摸屏背面的显示元件的显示内容进行视觉确认,一边利用手指或笔等方式按压触摸屏来进行操作。 Such an electronic device the user through the touch screen, while the display device display contents of the touch screen visually observing the back, while the use of a pen or a finger pressing the touch screen mode to operate. 由此,可以操作电子设备的各种功能。 Thereby, it is possible to operate various functions of the electronic devices.

[0004] 按照触摸屏的工作原理和传输介质的不同,现有的触摸屏通常分为四种类型,分别为电阻式、电容感应式、红外线式以及表面声波式。 [0004] The principle according to different transmission media and a touch screen, a conventional touch screen is usually divided into four types, including resistance, capacitance, infrared, and surface acoustic wave. 其中电阻式触摸屏的应用最为广泛,请参见文献“Production of Transparent ConductiveFilms with Inserted SiO2 Anchor Layer, and Application to a Resistive TouchPanel,,Kazuhiro No da, Kohtaro Tanimura· Electronics and Communications inJapan, Part 2,Vol. 84,P39-45 (2001)。 Wherein applying resistive touch screen most widely used, see the document "Production of Transparent ConductiveFilms with Inserted SiO2 Anchor Layer, and Application to a Resistive TouchPanel ,, Kazuhiro No da, Kohtaro Tanimura · Electronics and Communications inJapan, Part 2, Vol. 84, P39-45 (2001).

[0005] 现有的电阻式触摸屏一般包括一上基板,该上基板的下表面形成有一上透明导电层;一下基板,该下基板的上表面形成有一下透明导电层;以及多个点状隔离物(Dot Spacer)设置在上透明导电层与下透明导电层之间。 [0005] In a conventional resistive-type touch panel comprising an upper substrate, a lower surface of the upper substrate with a transparent conductive layer, an upper; a lower substrate, an upper surface of the lower substrate formed with a transparent lower conductive layer; and a plurality of dot spacers was (Dot Spacer) disposed between the transparent conductive layer and the lower transparent conductive layer. 其中,该上透明导电层与该下透明导电层通常采用具有导电特性的铟锡氧化物(Indium Tin Oxide, IT0)层(下称ITO层)。 Wherein the transparent conductive layer and the transparent conductive layer is usually the lower indium tin oxide (Indium Tin Oxide, IT0) layer (hereinafter referred to as ITO layer) having conductive property. 当使用手指或笔按压上基板时,上基板发生扭曲,使得按压处的上透明导电层与下透明导电层彼此接触。 When a finger or pen is pressed on the substrate, the upper substrate is distorted, so that the transparent conductive layer and pressed at a lower transparent conductive layer in contact with each other. 通过外接的电子电路分别向上透明导电层与下透明导电层依次施加电压,触摸屏控制器通过分别测量第一导电层上的电压变化与第二导电层上的电压变化,并进行精确计算,将其转换成触点坐标。 By sequentially applying an external electronic circuits upwardly transparent conductive layer and the transparent conductive layer a voltage, a touchscreen controller by measuring the voltage change in the voltage variation on the first conductive layer and the second conductive layers, and accurate calculation, which conversion into contact coordinates. 触摸屏控制器将数字化的触点坐标传递给中央处理器。 The touch screen controller digitized contact coordinates is transmitted to the central processor. 中央处理器根据触点坐标发出相应指令,启动电子设备的各种功能切换,并通过显示器控制器控制显示元件显示。 The central processor issues a command corresponding contact coordinates, various functions of the electronic device to start switching and display element through a display controller.

[0006] 然而,ITO层作为透明导电层通常采用离子束溅射或蒸镀等工艺制备,在制备的过程,需要较高的真空环境及需要加热到200〜3002C,因此,使得ITO层的制备成本较高。 [0006] However, the ITO layer as the transparent conductive layer is usually prepared by ion beam sputtering or other vapor deposition processes employed in the process of preparation, and require high vacuum environments require heating to 200~3002C, therefore, that the layer of ITO higher cost. 此外,ITO层作为透明导电层具有机械性能不够好、难以弯曲及阻值分布不均勻等缺点。 Further, the ITO layer as a transparent conductive layer having mechanical properties are not good enough, it is difficult to bend and uneven resistance and other shortcomings. 另外, ITO在潮湿的空气中透明度会逐渐下降。 Further, ITO transparency will gradually decline in moist air. 从而导致现有的电阻式触摸屏及显示装置存在耐用性不够好,灵敏度低、线性及准确性较差等缺点。 Resulting in the presence of durability is not good enough, low sensitivity, poor accuracy, and other shortcomings of conventional resistive touch screen and a display device. 由此可见,采用该触摸屏的触摸式液晶显示屏具有制备工艺繁杂,成本高,耐用性差,灵敏度低,且线性及准确性差等不足。 Thus, the use of the touch screen LCD touch panel having a complicated manufacturing process, high cost and poor durability, low sensitivity, accuracy, and poor and inadequate. 发明内容 SUMMARY

[0032] 请参阅图4,在上述拉伸过程中,在拉力作用下超顺排碳纳米管阵列中选定的部分碳纳米管沿拉伸方向逐渐脱离基底的同时,由于范德华力作用,该超顺排碳纳米管阵列中的其它碳纳米管首尾相连地连续地被拉出,从而形成一碳纳米管膜。 [0032] Referring to FIG 4, in the above-described stretching process, the selected super-aligned carbon nanotube array in the section under tension in the stretching direction moving away from the substrate, while the carbon nanotubes, due to the van der Waals force, the other super-aligned carbon nanotube carbon nanotube array is connected end to end to be drawn out continuously, to thereby form a carbon nanotube film. 该碳纳米管膜包括多个碳纳米管首尾相连且沿拉伸方向定向排列。 The carbon nanotube film includes a plurality of carbon nanotubes joined end to end and aligned in the stretching direction. 该直接拉伸获得的择优取向排列的碳纳米管膜比无序的碳纳米管膜具有更好的均勻性,即具有更均勻的厚度以及更均勻的导电性能。 Preferred orientation of the carbon nanotube film obtained in direct tension arrangement with better uniformity than the disordered carbon nanotube film, i.e., a more uniform thickness and more uniform conductivity. 同时该直接拉伸获得碳纳米管膜的方法简单快速,适宜进行工业化应用。 Meanwhile, the method directly obtained stretched carbon nanotube film is simple and fast, and suitable for industrial application.

[0035] 其次,采用激光处理上述碳纳米管膜。 [0035] Next, the above-described carbon nanotube film by laser processing.

[0036] 由于碳纳米管膜中的碳纳米管之间存在范德华力,碳纳米管膜中的某些碳纳米管容易聚集形成碳纳米管束,该碳纳米管束直径较大,影响了碳纳米管膜的透光性。 [0036] Due to the presence of van der Waals forces between the carbon nanotubes in the carbon nanotube film, some of the carbon nanotube in the carbon nanotube film is easily aggregated to form the carbon nanotube bundles, the larger diameter of the carbon nanotube bundles, the carbon nanotube Effect translucent film. 为提高碳纳米管膜的透光性,以功率密度大于0.1 X IO4瓦特/平方米的激光照射该碳纳米管膜,除去碳纳米管膜中直径较大,透光性较差的碳纳米管束。 To improve the light transmissive carbon nanotube film, at a power density of greater than 0.1 X IO4 W / m laser irradiation of the carbon nanotube film, the carbon nanotube film is removed larger diameter, the carbon nanotube bundles translucent poor . 采用激光处理碳纳米管膜的步骤可以在含氧环境中进行。 Laser processing step may be a carbon nanotube film in an oxygen atmosphere. 优选地,激光处理碳纳米管膜的步骤在空气环境下进行。 Preferably, the laser processing step is performed in a carbon nanotube film under an air atmosphere.

[0037] 采用激光处理上述碳纳米管膜可以通过固定碳纳米管膜,然后移动激光装置照射该碳纳米管膜的方法实现;或通过固定激光装置,移动碳纳米管膜使激光照射该碳纳米管膜的方法实现。 [0037] The laser processing described above by fixing the carbon nanotube film can be a carbon nanotube film, and then irradiating laser device moving method the carbon nanotube film is achieved; or by fixing the laser device, the laser light irradiating the carbon nanotube film moves the carbon nano the method of ependymal achieved.

[0038] 上述激光照射碳纳米管膜的过程中,由于碳纳米管对激光具有良好的吸收特性, 而激光为一具有较高能量的光,被碳纳米管膜吸收后会产生一定的热量,使碳纳米管膜中的碳纳米管升温。 [0038] The above-described laser irradiation process carbon nanotube film, since carbon nanotubes have good absorption characteristics for laser light, the laser light having a higher energy, is absorbed by the carbon nanotube film will produce some heat, carbon nanotube in the carbon nanotube film heating. 碳纳米管膜中,直径较大的碳纳米管束吸收的热量较多,因此,所述碳纳米管束中的碳纳米管的温度较高,当碳纳米管的温度达到足够高时(一般大于600°C ),碳纳米管束被激光烧掉。 Carbon nanotube film, the larger diameter of the carbon nanotube bundles absorb more heat, thus, the higher the temperature the carbon nanotube in the carbon nanotube bundles, the carbon nanotube when the temperature reaches a sufficiently high (typically greater than 600 ° C), the carbon nanotube a laser beam is burned. 相对于激光处理前的碳纳米管膜,激光处理后的碳纳米管膜的透光性有显著的提高,其透光率大于70%。 With respect to the carbon nanotube film before laser processing, light transmissive carbon nanotube film after the laser treatment a significant increase, greater than 70% transmittance.
