需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请实施例提供一种触控屏控制方法，该触控屏控制方法应用于电子设备，该电子设备在被用户握持时，用户手指接触的区域为触摸区域。示例性的，该电子设备 的屏幕可以是侧边有弧度的曲面屏，也可以是折叠屏。本申请实施例对于电子设备的屏幕的具体形态并不进行限定，在此仅以电子设备的屏幕为曲面屏和折叠屏为例进行说明。实际应用中，电子设备的屏幕也可以是其他形态的。
示例性的，电子设备的屏幕是侧边有弧度的曲面屏。如图1所示，以电子设备是图1所示的曲面屏手机为例。图1中的(a)示出曲面屏手机100的立体图。图1中的(b)示出曲面屏手机100的主视图。如图1中的(a)和图1中的(b)所示，手机100的屏幕是左侧边10和右侧边20有弧度的曲面屏。
其中，由于曲面屏手机的屏幕是侧边有弧度的曲面屏；因此，用户握持曲面屏手机时，用户手指会大面积接触屏幕的侧边弧度区域。例如，如图1中的(c)所示，以用户右手握持曲面屏手机为例。用户右手的虎口和大拇指与曲面屏的右侧弧度区域接触，用户右手的其他手指与曲面屏的左侧弧度区域接触。
示例性的，上述曲面屏手机的侧边弧度区域可以通过特殊的功能和手势，实现侧边交互。例如，侧边弧度区域可以通过手势操作实现音量调节、快捷拍照等功能。再例如，通过侧边弧度区域可以检测用户的左手或右手。本申请实施例对于侧边弧度区域的具体功能并不进行限定，在此仅是示例性说明。
示例性的，电子设备的屏幕是折叠屏。以电子设备是折叠屏手机为例。该折叠屏手机可以分为两类。一类为朝外翻折的折叠屏(简称外折折叠屏)，另一类为朝内翻折的折叠屏(简称内折折叠屏)。其中，以折叠屏可折叠分为主屏和副屏为例。内折折叠屏被折叠后，主屏和副屏相对，对用户不可见。外折折叠屏被折叠后，主屏和副屏相背对，对用户可见。可以理解的，该折叠屏可以是上下折叠，也可以是左右折叠，本申请实施例对此并不进行限定。在此仅是外折折叠屏，左右折叠为例进行说明。
例如，如图2所示，为本申请实施例提供的一种具有外折折叠屏的手机的产品形态示意图。其中，图2中的(a)是外折折叠屏处于完全展开状态时的形态示意图。随着电子设备的折叠，该外折折叠屏可折叠为图2中的(b)所示的半折叠状态的形态，包括主屏、副屏和侧边屏。该外折折叠屏可继续折叠为图2中的(c)所示的折叠状态的折叠屏。如图2中的(c)所示，折叠屏手机被完全被折叠后，主屏和副屏相背对，对用户可见。
其中，由于折叠屏手机的触摸屏在折叠状态下侧边屏可触摸；因此，用户握持折叠屏手机时，用户手指会大面积接触触摸屏的侧边区域，用户手心会接触主屏或副屏。例如，如图2中的(d)所示，以用户右手握持折叠屏手机为例，用户右手的虎口和大拇指与折叠屏手机的侧边屏区域接触，用于手心与折叠屏手机的主屏区域接触，折叠屏手机的副屏朝向用户。
示例性的，上述图1-图2所示的电子设备的屏幕可以为电容式触摸屏。该电容式触摸屏可以通过任何持有电荷的物体包括人体皮肤工作。该电容式触摸屏可以为自电容屏，也可以为互电容屏，还可以为自电容和互电容相结合的触摸屏，本申请实施例对此并不进行限定。下述实施例仅以电容式触摸屏为互电容屏为例进行说明。
示例性的，互电容屏是在玻璃表面用纳米铟锡金属氧化物(Indium Tin Oxides，ITO)制作横向电极与纵向电极，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， 从而改变了两个电极之间的电容量。检测互电容大小时，纵向的电极依次发出激励信号，横向的所有电极同时接收信号，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。可以理解的，上述电子设备也可以通过横向电极依次发出激励信号，纵向的所有电极同时接收信号，本申请实施例对此并不进行限定。发出激励信号的电极可以称为驱动电极，接收信号的电极可以称为接收电极。
示例性的，电容屏的触摸原理：当用户手指触摸屏幕时，检测互电容的电容量，并将该电容量减去基准值(baseline)得到差值(rawdiff)。当rawdiff超过手指门限(finger threshold)时，可以确定有手指触摸屏幕，并确定出触摸屏幕的手指数量以及用户触摸的位置信息等。这里，基准值是根据触摸屏未被触摸时的电容量(可以称为本底电容)设定的一个值，由于触摸屏上不同区域的本底电容往往并不一致，因此基准值通常可以设为触摸屏上多个区域的本底电容的平均值，或者设为上述多个区域的本底电容的最大值，或者设为上述平均值或者最大值加上一个常数，或者设为比上述平均值或者最大值大的某个值，本申请对此不作限定。
传统上，电子设备的屏幕仅设置一个基准值，当电子设备的触摸屏未被用户触摸时，由于电容的容值会随着温度、湿度、噪声、充电器干扰等多个因素动态变化，因此基准值也将随着电容的容值的变化进行动态更新，从而使得电子设备能够灵敏的识别用户的触摸操作。但是，当用户触摸电子设备的屏幕时，该基准值会停止更新，否则将会把用户触摸的信号一起更新掉，无法继续做触摸检测。因此，在电子设备被用户握持时，用户手指接触的区域为触摸区域的情况下，基准值会停止更新。但是，在用户握持电子设备的过程中，受环境温度、湿度、噪声等干扰因素的影响，电容的容值将发生变化，如果基准值不及时更新，将导致用户触摸屏幕异常的情况发生，用户体验不佳。
例如，电子设备的触摸屏是侧边有弧度的曲面屏，或者，折叠屏时，在电子设备仅维护一个基准值的情况下，当用户握持电子设备时，用户手指与触摸屏接触，基准值停止更新。但如果电子设备受充电影响，温度较高，那么电容的容值将会发生较大变化，如果基准值不随之更新，将导致用户触摸不灵活或触摸无法识别等情况发生，造成用户体验不佳。

S401、电子设备接收屏幕的第一区域的第一触摸信号。
其中，该电子设备的屏幕包括第一区域和第二区域，第一区域和第二区域分别对应一个基准值(baseline)，该基准值与其对应的区域未被触摸时的电容值相对应。例如，以第一区域对应的第一基准值为例，该第一基准值与第一区域未被用户触摸时的电容值相对应。示例性的，当用户手指触摸第一区域时，电子设备检测电容的电容量，并将该电容量减去第一基准值(baseline)，得到差值(rawdiff)。当rawdiff超过手指门限(finger threshold)时，可以确定有手指触摸屏幕。因此，该基准值可以用于确定电子设备的屏幕是否被用户触摸。可选的，上述第一区域和第二区域设置的手指门限可以相同，也可以不同，本申请实施例对此并不进行限定。
可选的，电子设备的屏幕还可以包括第一区域和第二区域以外的区域。例如，第三区域等。可以理解的，电子设备的屏幕可以被划为至少两个区域，该至少两个区域可以构成电子设备完整的屏幕，该至少两个区域包括上述第一区域和上述第二区域。

示例性的，上述每个区域之间互不重叠。例如，电子设备的屏幕包括第一区域和第二区域时，该第一区域和第二区域互不重叠。再例如，电子设备的屏幕包括第一区域、第二区域和第三区域时，该第一区域、第二区域、第三区域之间互不重叠。
例如，电子设备为图1所示的侧边有弧度的曲面屏手机，该电子设备的屏幕可以包括主控屏区域和侧边曲面屏区域。或者，电子设备的屏幕可以包括主控屏区域、第一侧边曲面屏区域和第二侧边曲面屏区域。
例如，如图5中的(a)所示，电子设备可以将曲面屏手机的屏幕划分为两个区域，分别为区域1和区域2，其中区域1为主控屏区域，区域2为侧边曲面屏区域，上述第一区域为区域1，上述第二区域为区域2。再例如，如图5中的(b)所示，电子设备可以将曲面屏手机的屏幕划分为三个区域，分别区域1、区域2和区域3，其中，区域1为主控屏区域，区域2为左侧边曲面屏区域，区域3为右侧边曲面屏区域，上述第一区域为区域3，上述第二区域为区域1，第三区域为区域2。本申请实施例对于电子设备的屏幕的具体划分原则并不进行限定，在此仅以图5为例进行示例性说明。
示例性的，每个区域对应一个基准值。即电子设备可以维护多个基准值，该多个基准值分别对应不同的区域，每个区域对应一个基准值。例如，以图5中的(b)所示的屏幕划分方式为例，电子设备可以维护3个基准值，分别为baseline 1、baseline 2和baseline 3，其中，区域1对应baseline 1，区域2对应baseline 2，区域3对应baseline 3。
可以理解的，本实施例与现有技术的区别在于，现有技术中的电子设备仅维护一个基准值，而本实施例中电子设备可以维护多个基准值，而且每个区域维护一个基准值。
示例性的，上述第一区域为电子设备被用户握持时，用户手触摸的区域。例如，第一区域可以为侧边曲面屏区域；或者，第一区域可以为第一侧边曲面屏区域和第二侧边曲面屏区域中的至少一个区域。
例如，以图5中的(a)所示的区域划分方式为例，结合图6中的(a)所示。用户用右手握持电子设备时，用户右手的虎口和大拇指与曲面屏的右侧弧度区域(区域2)接触，用户右手的其他手指与曲面屏的左侧弧度区域(区域2)接触。该区域2为第一区域。
再例如，以图5中的(b)所示的区域划分方式为例，结合图6中的(b)所示。用户用右手握持电子设备时，用户右手的虎口和大拇指与曲面屏的右侧弧度区域(区域3)接触，用户右手的其他手指与曲面屏的左侧弧度区域(区域3)接触。该区域3为第一区域。
示例性的，电子设备可以接收用户对第一区域(图6中的(a)中的区域2或图6中的(b)中的区域3)的第一触摸信号。
S402、电子设备响应于第一区域的第一触摸信号，电子设备维持第一区域对应的基准值不变。
示例性的，以图5中的(a)所示的区域划分方式为例，结合图6中的(a)所示，电子设备响应于用户对第一区域(区域2)的握持，电子设备维持第一区域(区域2) 对应的基准值不变。即电子设备不更新用户握持电子设备时触摸的区域2对应的baseline 2。
示例性的，以图5中的(b)所示的区域划分方式为例，结合图6中的(b)所示，电子设备响应于用户对第一区域(区域3)的握持操作，电子设备维持第一区域(区域3)对应的基准值不变。即电子设备不更新用户握持电子设备时触摸的区域3对应的baseline 3。
可以理解的，本申请的实施例可以维护多个基准值，每个区域对应一个基准值，在用户触摸第一区域时，电子设备不更新该第一区域对应的基准值。
例如，如图6中的(b)所示，如果电子设备仅维护一个基准值，在用户握持区域3时，电子设备将停止更新该基准值。那么，当电子设备中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于基准值停止更新，因此用户再对区域1进行触摸操作后，电容量与基准值的差值(rawdiff)，可能不会超过手指门限，从而造成电子设备无法识别用户的触摸操作的问题。而本实施例中，通过对3个区域分别设置3个baseline，在用户握持区域3的同时，用户对区域1进行触摸操作时，电子设备不更新区域3对应的baseline3。由于区域1对应baseline1、区域2对应的baseline2，因此，因此电子设备不更新区域3对应的baseline3，并不会对区域1对应baseline1和区域2对应的baseline2造成任何影响。例如，电子设备可以继续更新区域1对应的baseline1和区域2对应的baseline2。从而使得区域1中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于该区域1对应的baseline1随着电容容值的变化在动态更新，因此，用户再对区域1进行触摸操作后，电子设备能够根据电容量与基准值的差值(rawdiff)，与手指门限进行比较，快速地识别出上述触摸操作。
本申请实施例提供的触控屏控制方法，通过电子设备接收用户对屏幕的第一区域的第一触摸信号；其中，该电子设备的屏幕包括第一区域和第二区域，每个区域对应一个基准值(baseline)，该基准值与其对应的区域未被触摸时的电容值相对应；电子设备响应于第一区域的第一触摸信号，电子设备维持第一区域对应的基准值不变。本实施例通过维护多个基准值，能够在用户握持第一区域时，停止更新该第一区域对应的基准值，由于第二区域对应的是另一个基准值，因此，电子设备停止更新用户触摸的第一区域对应的基准值时，第二区域对应的基准值可以继续更新，从而能够使得电子设备能够快速准确的识别用户对第二区域的触摸操作，提升用户体验。
示例性的，本申请实施例还提供一种触控屏控制方法，如图7所示，在上述步骤S401-S402的基础上，还可以包括S403。
S403、当电子设备未检测到第二区域的第二触摸信号时，电子设备更新第二区域对应的基准值。
示例性的，该第二触摸信号可以为用户对第二区域的触摸操作，例如，点击或滑动等操作。
示例性的，以图5中的(a)所示的区域划分方式为例，结合图6中的(a)所示，电子设备响应于用户对第一区域(区域2)的触摸，电子设备维持第一区域(区域2)对应的基准值不变；电子设备未检测到第二区域(区域1)的触摸信号，更新第二区域(区域1)对应的基准值。即电子设备不更新用户触摸的区域2对应的baseline 2， 更新未被用户触摸的区域1对应的基准值baseline1。
示例性的，在电子设备的屏幕包括第一区域、第二区域和第三区域的情况下，上述步骤S403还可以扩展为：当电子设备未检测到第二区域的第二触摸信号和第三区域的第三触摸信号时，电子设备分别更新第二区域和第三区域的基准值。即用户未触摸第二区域和第三区域时，电子设备可以分别更新第二区域和第三区域对应的基准值。
示例性的，以图5中的(b)所示的区域划分方式为例，结合图6中的(b)所示，电子设备响应于用户对第一区域(区域3)的触摸操作，电子设备维持第一区域(区域3)对应的基准值不变；电子设备未检测到第二区域(区域1)和第三区域(区域2)的触摸信号，分别更新第二区域(区域1)和第三区域(区域2)对应的基准值。即电子设备不更新用户触摸的区域3对应的baseline 3，分别更新未被用户触摸的区域1对应的基准值baseline1和区域2对应的基准值baseline2。
可选地，也可以把图5中的(b)中的区域1和区域2的并集作为第二区域。
可以理解的，本申请的实施例可以维护多个基准值，每个区域对应一个基准值。在用户触摸第一区域时，电子设备不更新该第一区域对应的基准值，在用户未触摸第二区域时，电子设备更新第二区域对应的基准值。从而使得用户触摸第一区域时，由于第二区域的基准值随该第二区域的电容的容值动态更新，因此，用户再对第二区域进行触摸操作时，电子设备能够灵敏的识别用户对第二区域的触摸操作。
例如，如图6中的(b)所示，如果电子设备仅维护一个基准值，在用户握持区域3时，电子设备将停止更新该基准值。那么，当电子设备中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于基准值停止更新，因此用户对区域1进行触摸操作后，电容量与基准值的差值(rawdiff)，可能不会超过手指门限，从而造成电子设备无法识别用户的触摸操作的问题。而本实施例中，通过对3个区域分别设置3个baseline，在用户握持区域3时，电子设备不更新区域3对应的baseline3，但更新区域1对应的baseline1和区域2对应的baseline2。从而使得区域1中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于该区域1对应的baseline1随着电容容值的变化在动态更新，因此，用户再对区域1进行触摸操作后，电子设备能够根据电容量与基准值的差值(rawdiff)，与手指门限进行比较，快速地识别出上述触摸操作。
可选的，上述电子设备更新区域1和区域2的基准值的更新原则可以相同。该区域1的基准值1和区域2的基准值2，将分别随着区域1和区域2的电容值的变化而动态更新，从而使得用户对区域1和区域2进行触摸操作时，区域1和区域2能够识别用户的触摸操作。

例如，如图9所示，用户握持区域3时，响应于用户对区域3的第一触摸信号，电子设备可以降低区域3中的驱动电极发出激励信号的频率，即电子设备降低图9中的区域3中的纵向电极发出激励信号的频率，从而降低电子设备屏幕的功耗。例如，用户握持区域3时，电子设备可以将区域3中的纵向电极的发射频率从120Hz降低到30Hz，甚至更低，从而降低屏幕的整体功耗。本申请实施例对于驱动电极频率降低的幅度并不进行限定，在此仅是示例性说明。

示例性的，当用户不再触摸第一区域时，电子设备可以将第一区域的驱动电极的发射频率恢复至正常频率。例如，当用户不再握持区域3时，区域3的驱动电极的发射频率将恢复至120Hz，以确保用户再次触摸该区域3时，电子设备能够快速识别用 户的触摸操作。
本申请实施例提供的触控屏控制方法，通过电子设备接收用户对屏幕的第一区域的第一触摸信号；其中，该电子设备的屏幕包括第一区域和第二区域，每个区域对应一个基准值(baseline)，该基准值与其对应的区域未被触摸时的电容值相对应；电子设备响应于第一区域的第一触摸信号，电子设备维持第一区域对应的基准值不变；当电子设备未检测到第二区域的第二触摸信号时，电子设备更新第二区域对应的基准值；电子设备响应于第一区域的第一触摸信号，电子设备减小第一区域中的驱动电极的发射频率；在第一区域不被用户握持的情况下，电子设备恢复第一区域中的驱动电极的发射频率。本实施例通过维护多个基准值，能够在用户触摸第一区域时，停止更新该第一区域对应的基准值，在用户未触摸第二区域时，更新第二区域对应的基准值，从而能够使得电子设备能够快速准确的识别用户对第二区域的触摸操作，提升用户体验。而且，本实施例在用户触摸第一区域时，通过降低第一区域中的驱动电极的发射频率，能够节省电子设备的屏幕的功耗，并在用户不再触摸第一区域时，通过恢复第一区域的驱动电极的发射频率，从而能够确保用户再次触摸第一区域时，电子设备能够快速识别用户对第一区域的触摸操作。
本申请实施例提供又一种触控屏控制方法，该方法可以应用于可折叠的电子设备，如图11所示，该触控屏控制方法包括步骤S1101-S1102。
S1101、电子设备接收屏幕的第一区域的第一触摸信号。
其中，该电子设备的屏幕包括第一区域和第二区域，在电子设备处于折叠状态的情况下，第一区域和第二区域分别对应一个基准值(baseline)，该基准值与其对应的区域未被触摸时的电容值相对应。关于基准值和第一触摸信号的相关描述可以参考步骤S401，在此不再赘述。
示例性的，上述每个区域之间互不重叠。该电子设备的屏幕可以包括主屏区域、副屏区域以及侧边屏区域。例如，如图12所示，电子设备可以将折叠屏手机的屏幕划分为三个区域，分别为区域1、区域2和区域3，其中区域1为主屏区域，区域2为副屏区域，区域3为侧边屏区域。本申请实施例对于至少两个区域的划分原则并不进行限定，在此仅以图12为例进行示例性说明。第一区域可以为主屏区域、副屏区域以及侧边屏区域中的至少一个区域。
示例性的，上述电子设备处于折叠状态是指电子设备的主屏和副屏的夹角小于第一预设角度阈值的状态。例如，以该第一预设角度阈值为30°为例。如图12所示，电子设备的主屏和副屏的夹角α小于30°的状态即为折叠状态。可以理解的，电子设备可以根据图3中的陀螺仪传感器380B和/或加速度传感器380E确定主屏和副屏的夹角。例如，电子设备可以根据主屏和副屏的陀螺仪传感器分别测量主屏和副屏的朝向(即朝向的方向向量)，再根据测量得到的主屏和副屏的朝向的角度变化，可以确定出主屏和副屏的夹角。本申请实施例对于第一预设角度阈值的具体取值并不进行限定，在此仅以30°进行示例性说明。
示例性的，如图12所示，在电子设备为折叠状态的情况下，上述每个区域对应一个基准值。即在电子设备为折叠状态的情况下，该电子设备可以维护多个基准值，该多个基准值分别对应不同的区域，每个区域对应一个基准值。例如，以上述至少两个 区域按照图12所示的划分方式为例，电子设备可以维护3个基准值，分别为baseline 1、baseline 2和baseline 3，其中，区域1对应baseline 1，区域2对应baseline 2，区域3对应baseline 3。
可以理解的，本实施例与现有技术的区别在于，现有技术中的电子设备仅维护一个基准值，而本实施例在电子设备处于折叠状态的情况下，电子设备可以维护多个基准值，而且每个区域维护一个基准值。
如图13所示，用户用右手握持电子设备时，用户右手的虎口和大拇指与折叠屏手机的侧边屏区域(区域3)接触，用户右手的手心与折叠屏手机的主屏区域(区域1)接触。即第一区域为区域1和区域3。
示例性的，电子设备可以接收用户对第一区域(图13中的区域1和区域3)的第一触摸信号。
S1102、在电子设备处于折叠状态的情况下，响应于第一区域的第一触摸信号，电子设备维持第一区域对应的基准值不变。
示例性的，结合图13所示，在电子设备处于折叠状态的情况下，电子设备响应于用户对第一区域(区域1和区域3)的第一触摸信号，电子设备维持第一区域(区域1和区域3)的基准值不变。即电子设备不更新用户握持的区域1的baseline 1和区域3的baseline 3。
可以理解的，本实施例在电子设备处于折叠状态的情况下，可以维护多个基准值，在用户握持第一区域时，电子设备不更新该第一区域对应的基准值。
例如，如图13所示，如果电子设备仅维护一个基准值，在用户握持区域1和区域3时，电子设备将停止更新该基准值。那么，当电子设备中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于基准值停止更新，因此用户再对区域2进行触摸操作(例如，点击操作或滑动操作等)后，电容量与基准值的差值(rawdiff)，可能不会超过手指门限，从而造成电子设备无法识别用户的点击操作的问题。而本实施例中，通过对3个区域分别设置3个baseline，在用户握持区域1和区域3时，电子设备不更新区域1对应的baseline 1和区域3对应的baseline3。由于区域2对应的baseline2，因此电子设备不更新可以更新区域1对应的baseline 1和区域3对应的baseline3，并不会对区域2对应的baseline2造成任何影响。例如，电子设备可以继续更新区域2对应的baseline2。从而使得区域2中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于该区域2对应的baseline2随着电容容值的变化在动态更新，因此，用户再对区域2进行触摸操作后，电子设备能够根据电容量与基准值的差值(rawdiff)，与手指门限进行比较，快速地识别出该触摸操作。
本申请实施例提供的触控屏控制方法，通过电子设备接收用户对屏幕的第一区域的第一触摸信号；其中，该电子设备的屏幕包括第一区域和第二区域，在电子设备处于折叠状态的情况下，每个区域对应一个基准值，该基准值与其对应的区域未被触摸时的电容值相对应；在电子设备处于折叠状态的情况下，响应于第一区域的第一触摸信号，电子设备维持第一区域对应的基准值不变。本实施例通过在电子设备处于折叠状态的情况下维护多个基准值，能够在用户握持第一区域时，停止更新该第一区域对应的基准值，由于第二区域对应的是另一个基准值，因此，电子设备停止更新用户触 摸的第一区域对应的基准值时，第二区域对应的基准值可以继续更新，从而能够使得电子设备能够快速准确的识别用户对第二区域的触摸操作，提升用户体验。
示例性的，本申请实施例还提供一种触控屏控制方法，如图14所示，在上述步骤S1101-S1102的基础上，还可以包括S1103。

示例性的，结合图13所示，在电子设备处于折叠状态的情况下，电子设备响应于用户对第一区域(区域1和区域3)的第一触摸信号，电子设备维持第一区域(区域1和区域3)的基准值不变；电子设备未检测到第二区域(区域2)的触摸信号时，更新第二区域(区域2)的基准值。即电子设备不更新用户触摸的区域1的baseline 1和区域3的baseline 3，更新未被用户触摸的区域2对应的baseline2。
可以理解的，本实施例在电子设备处于折叠状态的情况下，可以维护多个基准值，在用户触摸第一区域时，电子设备不更新该第一区域对应的基准值，在用户未触摸第二区域时，电子设备更新第二区域对应的基准值。从而使得用户触摸第一区域的时，由于第二区域的基准值随该第二区域的电容的容值动态更新，因此，用户再对第二区域进行操作时，电子设备能够灵敏的识别用户对第二区域的触摸操作。
例如，如图13所示，在用户握持电子设备(用户握持区域1和区域3)时，如果电子设备仅维护一个基准值，在用户握持区域1和区域3时，电子设备将停止更新该基准值。那么，当电子设备中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于基准值停止更新，因此用户再对区域2进行触摸操作后，电容量与基准值的差值(rawdiff)，可能不会超过手指门限，从而造成电子设备无法识别用户的点击操作的问题。而本实施例中，通过对3个区域分别设置3个baseline，在用户握持区域1和区域3时，电子设备不更新区域1对应的baseline 1和区域3对应的baseline3，但更新区域2对应的baseline2。从而使得区域2中的电容的容值随着温度、湿度、噪声等干扰因素发生较大变化时，由于该区域2对应的baseline2随着电容容值的变化在动态更新，因此，用户再对区域2进行触摸操作后，电子设备能够根据电容量与基准值的差值(rawdiff)，与手指门限进行比较，快速地识别出该触摸操作。

S1104、在电子设备处于折叠状态的情况下，电子设备响应于第一区域的第一触摸信号，电子设备减小第一区域中的驱动电极的发射频率。
示例性的，结合图13所示，在电子设备处于折叠状态的情况下，电子设备响应于用户对第一区域(区域1和区域3)的第一触摸信号，电子设备可以减小区域1和区域3中的驱动电极发出激励信号的频率，从而降低屏幕的功耗。
示例性的，电子设备的屏幕中横向电极与纵向电极交叉的地方将会形成电容，上述驱动电极可以是纵向电极，也可以是横向电极。当驱动电极为纵向电极时，接收电极为横向电极。当驱动电极为横向电极时，接收电极为纵向电极。驱动电极依次发出激励信号，接收电极同时接收信号，可以得到所有横向和纵向电极交汇点的电容值大小。本实施例对于电子设备的驱动电极和接收电极的方向并不进行限定，在此仅以电子设备的屏幕中驱动电极为纵向电极，接收电极为横向电极为例进行说明。
例如，如图13所示，在电子设备处于折叠状态的情况下，用户握持区域1和区域3时，响应于用户对区域1和区域3的第一触摸信号，电子设备可以降低区域1和区域3中的驱动电极发出激励信号的频率，即电子设备降低图1中的区域1和区域3中的纵向电极发出激励信号的频率，从而降低电子设备屏幕的功耗。例如，用户触摸区域1和区域3时，电子设备可以将区域1和区域3中的纵向电极的发射频率从120Hz降低到30Hz，甚至更低，从而降低屏幕的整体功耗。本申请实施例对于驱动电极频率降低的幅度并不进行限定，在此仅是示例性说明。
