Description

具有集成触摸屏的显示设备及其驱动方法
本申请是申请日为2012年12月28日、申请号为201210583979.0、发明名称为“具有集成触摸屏的显示设备及其驱动方法”的发明专利申请的分案申请。
相关申请的交叉引用
本申请要求于2012年5月30日提交的申请号为10-2012-0057525的韩国专利申请的优先权，通过引用将其并入这里，如在此完全阐述一样。
技术领域
本发明涉及显示设备，更具体地，涉及具有集成触摸屏的显示设备。
背景技术
触摸屏是一种包括在诸如液晶显示器(LCD)、场发射显示器(FED)、等离子显示面板(PDP)、电致发光显示器(ELD)和电泳显示器(EPD)的图像显示设备的输入设备，并且触摸屏允许用户通过向触摸屏的触摸传感器施加压力(例如，按压或触摸)输入信息。对于诸如智能电话和个人计算机(PC)的具有集成触摸屏的显示设备的需求正在增长。
在下文中将参照图1描述相关技术的具有集成内嵌(in-cell)式触摸屏的显示设备。更具体地，图1是示出具有内嵌式集成自电容触摸屏的相关技术的显示设备的图。
如所示出的，相关技术的显示设备包括具有多个嵌入电极12的面板10、连接至外部系统并控制面板10内部的多条数据线13的显示驱动器IC(DD-IC)20以及驱动面板10内部的电极12的触摸IC 30。而且，以显示驱动模式和触摸驱动模式交替地驱动面板10，以此执行触摸功能和显示功能。
当面板10的驱动模式是显示驱动模式时，电极12作为用于显示驱动的多个公共电极通过连接线23接收公共电压，并且，数据线13接收来自显示驱动器IC 20的浮动电压或地电压以驱动液晶显示设备。
此外，当面板10的驱动模式是触摸驱动模式时，电极12作为多个触摸电极通过连接线23接收触摸扫描信号。如图1所示，连接线23连接至电极12。
因此，在相关技术的显示设备中，在触摸电极和数据线之间生成初始电容，并且初始电容越大，触感(touch sensation)越小。原因如下。
触感对应于信噪比(SNR)的大小，信噪比是通过用信号(当没有进行触摸时生成的信号)和信号(当进行触摸时生成的信号)的平均值除以当没有进行触摸时引起的噪声的最大值得到的值。因此，噪声越大，SNR的大小越小，从而，初始电容越大，触感越小。而且，噪声值就是初始电容值。
在下文中，将参照图2详细描述降低触感的初始电容。具体地，图2是示出图1中的相关技术显示设备的部分A的放大图。
如图2所示，在电极12之间形成2.85pF的初始电容，在数据线13之间形成1.6pF的初始电容。并且，在电极12和未与电极12交叠形成的数据线13之间形成98.5pF的初始电容，在电极12和与电极12的下部交叠形成的数据线13之间形成25.3pF的初始电容。
如图2所示，形成在电极12和数据线13之间的初始电容比形成在电极12之间的初始电容或形成在数据线13之间的初始电容相对更大。因此，相比于形成在电极12之间的初始电容或形成在数据线13之间的初始电容，形成在电极12和数据线13之间的初始电容会引起相对更大的噪声。因此，触感被降低。
因此，即使浮动电压或地电压在触摸驱动模式下被施加到数据线，但是在浮动电压在触摸驱动模式下被施加到数据线时还是会发生触摸故障，并且当地电压在触摸驱动模式下被施加到数据线时，初始电容增大，引起噪声的增大。而且，由于形成在电极和数据线之间的初始电容，触感和触摸的准确性降低。
发明内容
相应地，本发明的一个目的在于提供一种基本克服由于相关技术的局限或缺点引起的一个或多个问题的具有集成触摸屏的显示设备及其驱动方法。
本发明的另一个目的在于提供一种具有集成触摸屏的显示设备，该显示设备将由于数据线和自电容触摸屏内的电极之间生成的电容所引起的触感的降低最小化。
为了实现这些和其它的优点并根据本发明的目的，如这里所包括和大致描述的，一方面，本发明提供一种具有集成触摸屏的显示设备，所述显示设备具有：显示面板，该显示面板包括多条数据线和被分成多个块型组的多个电极；显示驱动器IC，该显示驱动器IC被配置为当所述面板的驱动模式是显示驱动模式时向所述电极施加公共电压，当面板的驱动模式是触摸驱动模式时向每个块型组顺序地施加触摸扫描信号，并且当所述触摸扫描信号被施加到对应的块型组时，向与所述对应的块型组关联的数据线施加数据信号；以及触摸IC，该触摸IC被配置为生成所述触摸扫描信号并向所述显示驱动器IC施加所述触摸扫描信号。
另一方面，本发明提供一种控制具有集成触摸屏的显示设备的方法，该方法包括：将所述显示设备的显示面板所包括的多个电极分成多个块型组，其中，所述显示面板还包括多条数据线；当所述面板的驱动模式是显示驱动模式时，通过所述显示设备的显示驱动器IC，向所述电极施加公共电压；当所述面板的驱动模式是触摸驱动模式时，通过所述显示驱动器IC，顺序地向每个块型组施加触摸扫描信号，并且当所述触摸扫描信号被施加到对应的块型组时，向与所述对应的块型组关联的数据线施加数据信号；以及通过所述显示设备的触摸IC，生成所述触摸扫描信号并将所述触摸扫描信号施加到所述显示驱动器IC。

在根据本发明实施方式的具有集成触摸屏的显示设备中，多个电极被分成n个组，触摸扫描信号被顺序地施加到n个组。为了方便，下文的描述假设电极被分成三个组。然而，本发明并不局限于将电极分成三个组，电极可以被分成四个组或更多个组。并且，连接触摸驱动器和多个电极的连接线形成为交叠在数据线和电极之间，该连接线连接至触摸驱动器和面板的电极以将触摸驱动器施加的多个信号施加到各电极。
更详细地，图3是示出根据本发明实施方式的具有集成触摸屏的显示设备的方框图。如图3所示，显示设备包括具有多个电极120和多条数据线130的面板100，该多个电极120被分成多个块型组110。
还包括显示驱动器IC 200和触摸IC 300，显示驱动器IC 200在面板100的驱动模式是显示驱动模式时将公共电压施加到电极120，在面板100的驱动模式是触摸驱动模式时将触摸扫描信号施加到每一组，并将直流(DC)电压施加到数据线130，触摸IC 300生成触摸扫描信号并将触摸扫描信号施加到显示驱动器IC 200。
此外，面板100可以包括形成在两个基板之间的液晶层。在面板100中，多条数据线130和多条选通线彼此交叉，多个像素由数据线130和选通线之间的交叉配置成矩阵类型，从而限定多个像素区域。此外，每条数据线130向像素施加数据信号以驱动液晶面板，并且每条数据线130可以形成在电极120下面。在此，为了简便而省略对选通线的描述。
而且，组110是块型组。块型组110仅向形成在接收触摸扫描信号的组的下面的数据线有效地施加数据信号。
因此，对于显示驱动模式，每个电极120从显示驱动器IC 200接收公共电压以作为公共电极。对于触摸驱动模式，每个电极120作为使用从触摸IC 300施加的触摸扫描信号感测触摸位置的触摸电极。并且，通过连接线230将公共电压和触摸扫描信号施加到各电极。
此外，虽然示出连接线230通过面板100的两侧与电极120相连接，但实际上连接线230与数据线130交叠。换句话说，连接线230在电极120和数据线130之间与数据线130交叠，并且连接线230连接至电极120。
进一步地，显示驱动器IC 200包括向电极120施加公共电压或通过组施加触摸扫描信号的触摸驱动器210，以及向数据线130施加DC电压的显示驱动器220。
更详细地，显示驱动器IC 200包括触摸驱动器210，当面板100的驱动模式是显示驱动模式时，触摸驱动器210向电极120施加由包括在显示驱动器IC 200中的公共电压发生器生成的公共电压，当面板100的驱动模式是触摸驱动模式时，触摸驱动器210将电极120分成三个组以向这三个组顺序地施加触摸扫描信号。进一步地，显示驱动器220向形成在该三个组中的接收触摸扫描信号的任意一组下面的数据线130施加DC电压。
例如，如图3所示，当从触摸驱动器210通过连接线230向第一组111施加用于感测触摸位置的触摸扫描信号时，DC电压从显示驱动器220被施加到形成在第一组111所包括的电极的下面的数据线131。当触摸扫描信号被施加到第二组112时，DC电压被施加到形成在第二组112所包括的电极的下面的数据线132。类似地，当触摸扫描信号被施加到第三组113时，DC电压被施加到形成在第三组113所包括的电极的下面的数据线133。
因此，DC电压被施加到形成在接收触摸扫描信号的组的下面的数据线，这减小了接收触摸扫描信号的组内的电极和形成在该组所包括的电极的下面的数据线之间形成的初始电容，从而防止了触感的降低。
这是因为，由于施加到接收触摸扫描信号的组内包括的电极的驱动电压，该组内包括的电极和数据线之间产生电势差，这增大了降低触感的初始电容。然而，通过向数据线施加DC电压，电极和数据线之间的电势差被最小化，使初始电容减小。
触摸IC 300通过包括在显示驱动器IC 200内的触摸驱动器210向组110施加触摸扫描信号，然后感测电极的电容变化以确定电容是否被触摸。
现在，将参照图3详细描述驱动根据本发明实施方式的具有集成触摸屏的显示设备的方法。在根据本实施方式的具有集成触摸屏的显示设备中，根据面板100的驱动模式，暂时区分并执行显示驱动和触摸驱动，并且显示驱动器IC 200生成同步信号以区分显示驱动模式和触摸驱动模式。
当面板100的驱动模式是显示驱动模式时，由包括在显示驱动器IC 200内的公共电压发生器生成的公共电压被同时施加到多个电极120，并且在显示驱动器IC 200内生成的DC电压或从外部施加到显示驱动器IC 200的DC电压通过显示驱动器220被施加到数据线130。
随后，电极120通过连接线230接收来自显示驱动器IC 200的公共电压以作为用于面板100的显示驱动的电极，并且多个像素通过数据线130接收用于驱动其数字逻辑的DC电压以作为用于显示驱动的像素。
然而，当面板100的驱动模式是触摸驱动模式时，在触摸IC 300内生成的用于感测触摸的三个分开的触摸扫描信号被施加到触摸驱动器210，并且在显示驱动器IC 200内生成的DC电压或从外部施加到显示驱动器IC 200的DC电压被施加到显示驱动器200。
随后，施加到触摸驱动器210的三个分开的触摸扫描信号通过连接线230被施加到形成在面板100内的相应的三个组110。例如，在三个分开的触摸扫描信号中，第一触摸扫描信号通过连接线230被施加到第一组111，第二触摸扫描信号被施加到第二组112，第三触摸扫描信号被施加到第三组113。这里，由于第一到第三触摸扫描信号中的每一个都被顺序地施加到对应组中所包括的电极，所以每个组内的多个电极被连接至连接线230。
同时，DC电压被顺序地从显示驱动器220施加到形成在面板100内接收触摸扫描信号的组中所包括的电极下面的数据线。例如，当从触摸驱动器210将触摸扫描信号施加到第一组111时，DC电压被从显示驱动器220施加到形成在第一组111所包括的电极的下面的数据线131。当从触摸驱动器210将触摸扫描信号施加到第二组112时，DC电压被施加到形成在第二组112中所包括的电极下面的数据线132。当从触摸驱动器210将触摸扫描信号施加到第三组113时，DC电压被施加到形成在第三组113中所包括的电极下面的数据线133。
随后，组110中所包括的电极120作为用于触摸驱动的电极，通过连接线230接收来自触摸驱动器210的触摸扫描信号，以检测用户的触摸位置，并将触摸位置传输至触摸IC300。
在本发明的一个实施方式中，形成在接收触摸扫描信号的组下面的多条数据线接收DC电压，并减小组(其接收触摸扫描信号)内的电极和形成在该组的下面的数据线之间形成的初始电容，从而防止触感的降低。
在本发明的另一个实施方式中，下面将再次参照图3详细描述减小接收触摸扫描信号的组内的电极和形成在该组下面的数据线之间所形成的初始电容的方法。
根据本发明实施方式的具有集成触摸屏的显示设备包括具有被分成块型组110的电极120的面板110以及数据线130。此外，当面板100的驱动模式是显示驱动模式时，显示驱动器IC 200向电极120施加公共电压，当面板100的驱动模式是触摸驱动模式时向每个组施加触摸扫描信号，并且向数据线130施加数据信号。还包括生成触摸扫描信号并向显示驱动器IC 200施加触摸扫描信号的触摸IC 300。除了DC电压发生器，本发明的这一实施方式基本上与本发明的另一实施方式相同，因此，没有提供重复的描述。下面的描述针对显示驱动器IC 200。
根据本发明的这一实施方式的显示驱动器IC 200包括向组110施加公共电压或通过组施加触摸扫描信号的触摸驱动器210，以及向数据线130施加数据信号的显示驱动器220。这里，施加到数据线130的数据信号是与触摸扫描信号具有相同相位的信号。
具体地，根据本发明的这一实施方式的显示驱动器IC 200包括触摸驱动器210，当面板100的驱动模式是显示驱动模式时，触摸驱动器210向电极120施加由包括在显示驱动器IC 200内的公共电压发生器产生的公共电压，并当面板100的驱动模式是触摸驱动模式时，将电极120分成三个组以将触摸扫描信号顺序地施加到这三个组。显示驱动器IC 200还包括显示驱动器220，当面板100的驱动模式是触摸驱动模式时，显示驱动器220向形成在该三个组中的接收触摸扫描信号的任意一个组下面的数据线130施加数据信号，该数据信号与触摸扫描信号具有相同相位。
例如，如图3所示，当从触摸驱动器210通过连接线230向第一组111施加用于感测触摸位置的触摸扫描信号时，具有与触摸扫描信号相同相位的数据信号从显示驱动器220被施加到形成在第一组111中所包括的电极下面的数据线131。当触摸扫描信号被施加到第二组112时，具有与触摸扫描信号相同相位的数据信号从显示驱动器220被施加到形成在第二组112中所包括的电极下面的数据线132。当触摸扫描信号被施加到第三组113时，具有与触摸扫描信号相同相位的数据信号从显示驱动器220被施加到形成在第三组113中所包括的电极下面的数据线133。
特别地，施加到形成在接收触摸扫描信号的组中所包括的电极下面的数据信号可以是以下的信号，其中，触摸IC 300施加到触摸驱动器220的触摸扫描信号被传输到显示驱动器210。
这里，与触摸扫描信号具有相同相位的数据信号被施加到形成在接收触摸扫描信号的组中所包括的电极下面的数据线，这减小了接收触摸扫描信号的组内的电极和形成在该组下面的数据线之间所形成的初始电容，从而防止触感的降低。
如上所述，这是因为，由于施加到接收触摸扫描信号的组中所包括的电极的触摸扫描信号，所以在该组中所包括的电极和数据线之间产生电势差。然而，通过向数据线施加具有与触摸扫描信号相同相位的数据信号，电极和数据线之间的电势差被最小化，从而使初始电容减小。
现在，将参考图3详细描述驱动根据本发明的这一实施方式的具有集成触摸屏的显示设备的方法。
根据本发明的这一实施方式，当面板100的驱动模式是显示驱动模式时，由包括在显示驱动器IC 200内的公共电压发生器所生成的公共电压被同时施加到多个电极120，并且电极120从显示驱动器IC 200接收公共电压以作为用于面板100的显示驱动的电极。
然而，当面板100的驱动模式是触摸驱动模式时，在触摸IC 300内生成的用于触摸感测的三个分开的触摸扫描信号被施加到触摸驱动器210，并且在显示驱动器IC 200内生成的数据信号通过显示驱动器220被施加到数据线130。这里，数据信号可以是由触摸驱动器210生成且被施加到显示驱动器220的信号，具体地，可以是触摸扫描信号。
随后，施加到触摸驱动器210的三个分开的触摸扫描信号通过连接线230被施加到形成在面板100内的相应的三个组110。例如，在三个分开的触摸扫描信号中，第一触摸扫描信号通过连接线230被施加到第一组111，第二触摸扫描信号被施加到第二组112，以及第三触摸扫描信号被施加到第三组113。这里，第一到第三触摸扫描信号中的每一个都被顺序地施加到对应组中所包括的多个电极。每个组内的该多个像素也连接至连接线230。
同时，数据信号被顺序地从显示驱动器220施加到形成在面板100内接收触摸扫描信号的组所包括的电极下面的数据线。这里，分别施加到形成在接收触摸扫描信号的组中所包括的电极下面的数据线的数据信号是与触摸扫描信号具有相同相位的信号。
例如，当触摸扫描信号从触摸驱动器210被施加到第一组111时，具有与触摸扫描信号相同相位的多个数据信号从显示驱动器220被分别施加到形成在第一组111中所包括的电极下面的数据线131。当触摸扫描信号从触摸驱动器210被施加到第二组112时，具有与触摸扫描信号相同相位的多个数据信号被分别施加到形成在第二组112中所包括的电极下面的数据线132。当触摸扫描信号从触摸驱动器210被施加到第三组113时，具有与触摸扫描信号相同相位的多个数据信号被分别施加到形成在第三组113中所包括的电极下面的数据线133。
在本发明的另一个实施方式中，形成在接收触摸扫描信号的组下面的多条数据线分别接收具有与触摸扫描信号相同相位的多个数据信号，并减小接收触摸扫描信号的组中所包括的电极和形成在该组中所包括的电极下面的数据线之间所形成的初始电容，从而防止触感的降低。
这是因为，由于施加到接收触摸扫描信号的组所包括的电极的触摸扫描信号，所以在该组中所包括的多个电极和数据线之间形成电势差。然而，通过向数据线施加具有与触摸扫描信号相同相位的数据信号，电极和数据线之间的电势差被最小化，从而使初始电容减小。
根据本发明的实施方式，在自电容触摸屏中，当触摸扫描信号被施加到一个组时，通过将DC电压施加给接收触摸扫描信号的该组所包括的电极的下面的数据线，该组的电极和该组下面的数据线之间的初始电容被最小化，从而使触摸感测更准确。
此外，根据本发明的实施方式，在自电容触摸屏中，当触摸扫描信号被施加到一个组时，通过将与触摸扫描信号具有相同相位的数据信号施加给接收触摸扫描信号的该组中所包括的电极下面的数据线，该组的电极和该组下面的数据线之间的初始电容被最小化，从而使触摸感测更准确。
对于本领域的技术人员而言将是显而易见的是，在不偏离本发明的精神和范围的前提下可以对本发明进行各种修改和变化。因此，本发明旨在涵盖在所附权利要求及其等同物的范围内的本发明的这些修改和变化。
