背景技术
随着电子产品的快速发展，具有多种应用功能的智能终端得以迅速普及，并成为深入至人类社会生活方方面面的终端产品。如今，用户不仅仅关注智能终端的功能，也越来也注重对智能终端的操作体验。
智能手机、平板电脑、笔记本、超极本电脑、视频播放器、电纸书和手持游戏机等智能终端，其款式主要有直板式、滑盖式和、折叠式等，它们的屏幕尺寸主要是7cm至38cm(3-15英寸)，对于上述每一款产品，屏幕太小则观赏效果差，屏幕太大又不方便携带，用户希望有更大的屏幕浏览网页、观看图片和视频，因此市场上出现了双屏幕的智能终端。
目前市场上的双屏手机和移动电脑，折叠后方便携带，打开屏幕水平对放时，两块屏幕能协同显示一个图像。但是，在两块屏幕中间都有屏幕的两个外壳边框，这样就不能达到双屏幕显示一个图像的完整效果；而且，现有的双屏幕手机和移动电脑，左右两部分是通过可转动的链接固定的，即，它们不能分离双屏单独使用。
专利CN200520038155.0公开了一种具有双屏幕结构的笔记本电脑，该笔记本电脑的两块屏幕能做360°旋转，实现双屏幕对接，但是图像中间还是有一条空白细缝，其图像显示不具备完整性，这种硬碰硬的对接方式很容易损害屏幕，而且它的两块屏幕对接的外壳边框条是一块圆弧形塑料板，这对塑料板伴随对接操作而自动打开，其长度和整机一样，这种帘布边框模式的塑料板没有和主机体紧密配合，携带和操作都很容易损害屏幕，屏幕寿命较短不具有实用性；而且，这款双屏幕笔记本电脑的两块屏幕不能分离，整体质量较重不便携带。专利CN200810101707.6公开了一种双屏幕笔记本电脑，它是在笔记本电脑的主机体后边中间位置设置一个转轴，该转轴两端分别设置一个转轴连接两块显示器，这种单轴旋转方式同时连接两个显示器，其稳定性较差；美国专利公开号US  D630206S1公开了一款双屏幕笔记本电脑，它是在显示器右边缘上设置一对转轴连接第二块显示器，向内折叠便于携带，向外打开实现双屏幕对接；美国专利公开号US8203832B2和美国专利申请号US20040051679A1两个专利公开两款相似的双屏幕笔记本电脑，这两款电脑都是在显示器顶部设置转轴连接第二块显示器，向内折叠便于携带，向上打开实现双屏幕对接，上述国内外专利公开的四款双屏幕笔记本电脑，都能实现双屏幕对接，但是它们的共同缺点是：双屏幕对接状态时，屏幕不能实现完美的无缝对接，两块屏幕的图像中间都有两条显示器外壳边框，双屏幕显示一个图像时其图像不完整，一个主机体配置两块显示器，质量较重不方便携带，且成本较高，它们的显示器和主机体也不能分离单独携带和使用。美国专利公开号US20120218191A1公开一款双屏幕平板电脑，它是在普通平板电脑的背面设置一块屏幕构成正反面的双屏幕平板电脑，这种双屏幕结构既不能拼接显示又不能分离使用；美国专利公开号US20110209102A1公开一款双屏幕平板电脑、美国专利公开号US D631043S1公开一款双屏幕平板电脑，上述平板电脑是由两块触摸屏组成，两块屏幕可以向内折叠，也可以向外打开平放，它们的共同缺陷是：双屏幕显示一个图像时中间有很宽的边框，双屏幕不能无缝显示一个图像，双屏幕两部分不能360°旋转，也不能分离单独使用。
综上所述，现有的手机、平板电脑、笔记本和超极本电脑、视频播放器、电纸书等智能终端，它们的主机、屏幕和边框都是固定的，其中尺寸小的携带方便，但是屏幕太小影响观看效果，相对尺寸更大的其观赏效果好点，但是又不方便携带，虽然在市场、技术和专利领域中出现了双屏幕的手机和移动电脑，综合上述分析得知，它们的质量、寿命、成本和图像效果都不理想，对于智能手机和移动电脑等智能终端，人们总希望有更大的屏幕浏览网页观看图片和视频，又要保持携带方便的特点，还希望节约成本。
因此，本发明提供了一种具有双显示屏幕的智能终端，所述智能终端包括：第一壳体、与所述第一壳体相对设置的第二壳体、可拆卸连接所述第一壳体、第二壳体的连接部；所述第一壳体包括形成所述第一壳体一表面的第一全面屏幕；所述第二壳体包括形成所述第二壳体一表面的第二全面屏幕；当所述智能终端处于单屏模式时，所述第二壳体收容于所述第一壳体下方，所述第二全面屏幕收容于所述第一全面屏幕下方；当所述智能终端处于双屏模式时，所述第二壳体相对于所述第一壳体展开，使得所述第一全面屏幕、第二全面屏幕组合形成为一完整的显示屏幕。本发明的技术方案，具有双屏组合模式、双屏单独模式、双屏分离模块、单屏模式等四种工作模式，根据需要，为用户提供不同的视觉效果及操作体验；本发明的两块显示屏幕能够实现无缝对接，达到双显示屏幕两倍面积的观赏图像视频的完整效果；本发明在显示屏幕对接时，不对显示屏幕造 成损伤，耐用、节约、环保；本发明能够在单屏模式下，或双屏分离后成为小巧一半的终端设备，更加方便单独携带和使用。

在一优选实施例中，所述第一全面屏幕14与所述第二全面屏幕15相向设置。
在一优选实施例中，所述第一全面屏幕14与所述第二全面屏幕15同向设置。
在一优选实施例中，第一全面屏幕14与第二全面屏幕15均为触摸屏幕。
目前电子设备常用的触摸屏技术共分五大类，即电阻式、表面电容式、投射电容式、表面声波式与红外线式等。前三种触摸屏技术因为装置体积较小，精密度相对可以做得更高，因此适用于体积小巧的便携式装置或者消费性电子产品。
电容式触控屏是利用人体的电流感应工作的。它是一块四层复合玻璃屏，玻璃屏的内表面和夹层各涂有一层ITO(即镀膜导电玻璃)，最外层是一薄层矽土玻璃保护层。ITO涂层作为工作面，四个角上引出四个电极，内层ITO为屏蔽层以保证良好的工作环境。当手指触摸在金属层上时，由于人体电场、用户和触控屏表面形成以一个耦合电容，对于高频电流来说，电容是直接导体，于是手指从接触点吸走一个很小的电流。这个电流分别从触控屏四角上的电极中流出，并且流经这四个电极的电流与手指到四角的距离成正比，控制器通过对这四个电流比例的精确计算，得出触摸点的位置信息。
电容式方案的结构和实现原理和电阻式完全不一样，主要是根据接触区域的电容量来判断手指的位置，所以目前只能通过手指来感应，并且可以对多点触摸等复杂的手势可以提供完善的支持。由于对外界的感应需要通过一层不导电的介电质(塑胶、玻璃等) 触摸屏需要贴合在上盖背面，所以对外界的抗干扰能力较强，可靠性和耐用性高。
电阻式触摸屏和电容式触摸屏各有优劣，但是随着多点触摸操作在智能手机上的广泛应用，只能实现单点操作的电阻式触摸屏已经无法满足用户的需要，电容式触摸屏已经成为了智能手机的主流。
电容式触摸技术是实现多点触控的希望所在，它需要一个或多个精心设计的、被刻蚀的ITO层，这些ITO层通过刻蚀形成多个水平和垂直电极，所有这些电极都由一个电容式感应芯片来驱动。该芯片既能将数据传送到一个主处理器，也能自己处理触摸点的XY轴位置。
投射电容屏可分为自电容屏和互电容屏两种类型。
在玻璃表面用ITO制作成横向与纵向电极阵列，这些横向和纵向的电极分别与地构成电容，这个电容就是通常所说的自电容，也就是电极对地的电容。当手指触摸到电容屏时，手指的电容将会叠加到屏体电容上，使屏体电容量增加。
在触摸检测时，自电容屏依次分别检测横向与纵向电极阵列，根据触摸前后电容的变化，分别确定横向坐标和纵向坐标，然后组合成平面的触摸坐标。自电容的扫描方式，相当于把触摸屏上的触摸点分别投影到X轴和Y轴方向，然后分别在X轴和Y轴方向计算出坐标，最后组合成触摸点的坐标。
如果是单点触摸，则在X轴和Y轴方向的投影都是唯一的，组合出的坐标也是唯一的；如果在触摸屏上有两点触摸并且这两点不在同一X方向或者同一Y方向，则在X和Y方向分别有两个投影，则组合出4个坐标。显然，只有两个坐标是真实的，另外两个就是俗称的“鬼点”。因此，自电容屏无法实现真正的多点触摸。
互电容屏也是在玻璃表面用ITO制作横向电极与纵向电极，它与自电容屏的区别在于，两组电极交叉的地方将会形成电容，也即这两组电极分别构成了电容的两极。当手指触摸到电容屏时，影响了触摸点附近两个电极之间的耦合，从而改变了这两个电极之间的电容量。检测互电容大小时，横向的电极依次发出激励信号，纵向的所有电极同时接收信号，这样可以得到所有横向和纵向电极交汇点的电容值大小，即整个触摸屏的二维平面的电容大小。根据触摸屏二维电容变化量数据，可以计算出每一个触摸点的坐标。因此，屏上即使有多个触摸点，也能计算出每个触摸点的真实坐标。
互电容屏的优点是布线较少，而且能同时识别和区分多个触点之间的差异，自电容屏也可感测多个触点，不过由于信号本身模糊，故不能区分。此外，互电容屏的感应方案还有速度快和功耗低的优势，因为其能同时测量一条驱动线路上的所有节点，所以可减少50％的采集周期数。这种双电极式结构具有自我屏蔽外部噪声的功能，在一定功率 级上可提高信号稳定性。
在任何情况下，触摸位置都是通过测量X电极和Y电极之间信号改变量的分配来确定的，随后会使用数学算法处理这些己改变的信号电平，以确定触摸点的XY坐标。
电容式触摸屏接收到触摸信号之后，将触摸数据转换成电脉冲，传送到触摸屏控制IC进行处理。信号先经过一个低噪声放大器LNA进行放大，然后通过模数转换和解调，最后送到一个DSP进行数据处理。
电容式触摸屏一般有M列N行个物理电容触摸传感器，这M列N行个相互交错的传感器组成了M×N个电容感应点，当用户的手指接近触摸屏的时候，其电容会随之改变。传感器的间隔，也就是相邻行或列间的距离，通常在几个毫米左右，这个间隔距离决定了触摸屏的物理分辨率M×N。
电容式触摸屏模块和LCD模块间的坐标系是完全不同的。LCD模块的像素坐标一般由它的分辨率决定，比如，一块WVGA的屏，它的分辨率为800×480，也就是说有800行，每行480个RGB像素。从而，一个具体位置可以由X和Y方向上像素点来确定。而电容式触摸屏模块则是根据其X和Y的方向上的原始物理尺寸来确定坐标系的。两坐标系间必须存在一个合理的映射方法，才可以保证输入和输出操作的正确性。
所以，触摸屏控制IC的DSP处理器还得对得到的数据进行电容式触摸屏模块和LCD模块间的像素映射转换，从而确保在触摸屏上感应到用户的触摸点就是用户所指的点。
另外，为了保持触摸坐标的稳定，触摸屏控制IC需要进一步处理触摸点的抖动，包括手指的抖动与电容数据的噪声，并根据坐标的变化来改变低通滤波器的滤波系数，实现对坐标的平滑处理。
最后，在把数据传到主机之前，还得使用软件分析数据，确定每次触摸是为了使用什么功能。这一过程包含确定屏幕上被触摸的区域大小、形状和位置。如果有必要，处理器会将相似的触摸整理分组。如果用户移动手指，处理器就会计算用户触摸的起点和终点间的差别。
-连接部13
第一壳体11与第二壳体12可拆卸连接的方式可以有多种，例如可以通过卡扣连接、粘结、磁性连接等连接方式将第一壳体11与第二壳体12可拆卸连接。

在一优选实施例中，所述智能终端100还包括一切换开关，切换开关设于所述第一壳体11与所述第二壳体12的连接部13，用于控制所述智能终端100的单屏模式及双屏模式的切换。
