Description

一种显示模组、电子设备及其控制方法
本申请要求于2020年02月14日提交国家知识产权局、申请号为202010093656.8、申请名称为“一种显示模组、电子设备及其控制方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种显示模组、电子设备及其控制方法。
背景技术
电子设备上使用的机械按键在长期使用的情况下会存在机械磨损的问题，甚至有潜在失效的风险。同时机械按键本身需要占据一定的空间，并且需要突出于整机，不利于实现整机一体化的设计的实现，尤其在瀑布屏移动终端的形态下，机械按键的取消成为必然。虽然外置单独的压力传感器方案可以解决上述问题，但是，由于外置的压力传感器需要在极为有限的空间内使用胶材固定在中框上，在跌落时可能脱落，可靠性风险高；同时组装的差异导致不同整机间的一致性差，还会增加额外的成本。
发明内容
本申请实施例提供一种显示模组、电子设备及其控制方法，能够将压力传感器集成于显示模组的层叠结构中，提高了产品的整体性和可靠性。
为达到上述目的，本申请实施例采用如下技术方案：
本申请实施例的第一方面，提供一种显示模组，包括显示区和非显示区；其中，非显示区包括压力传感器；压力传感器包括一个或多个压敏电阻，且至少一个所述压敏电阻与显示区的半导体有源层同层设置，且至少一个压敏电阻采用与半导体有源层相同的材料制作。示例性的，半导体有源层可以使用硅Si、金属氧化物等材料。由于半导体有源层具有压敏特性，即受到压力按压后改变电阻的特性，因此压力传感器的压敏电阻位于显示模组的半导体有源层。这样可以在制作显示模组的各材料层的同时将压力传感器的压敏电阻与显示区的多个压敏电阻，且至少一个压敏电阻与显示区的半导体有源层采用相同的材料同层制作，节省了空间，由于无需使用胶材固定，而是在显示模组的制程工艺中同步形成，提高了产品的整体性和可靠性。
在一种可能的设计中，根据压力传感器的电路设计需求，除压敏电阻外压力传感器还包括其他电阻，其他电阻与显示模组中除半导体有源层外的其他材料层同层。此处，其他材料层包括导线层或像素电极层。
在一种可能的设计中，提供了一种压力传感器的具体结构：压力传感器包括第一电阻、第二电阻、第三电阻以及第四电阻；其中第一电阻的第一端耦接第四电阻的第二端，第一电阻的第二端耦接第二电阻的第一端；第二电阻的第二端耦接第三电阻的第一端，第三电阻的第二端耦接第四电阻的第一端；第一电阻的第一端、第二电阻的第一端、第三电阻的第一端以及第四电阻的第一端分别通过导线耦接压力控制器，其中压力控制器用于向第一电阻的第一端输出入第一电压信号、向第三电阻的第一端输入第二电压信号；接收第二电阻的第一端输出的第三电压信号、接收第四电阻的第一端输出的第四电压信号，根据第三电压信号和第四电压信号获取所述压力传感器的电 阻变化量，并根据压力传感器的电阻变化量计算压力传感器被施加的压力。示例性的，第一电阻、第二电阻、第三电阻以及第四电阻满足如下关系：R1/R2＝R4/R3；R1为第一电阻的阻值，R2为第二电阻的阻值，R3为第三电阻的阻值，R4为第四电阻的阻值。
在一种可能的设计中，为了提高传感器输出信号的幅度，以提高传感器的灵敏性。第一电阻、第二电阻、第三电阻以及第四电阻在所述显示模组表面所在平面的投影中，第一电阻的投影与第三电阻的投影的中心距离小于或等于第一距离阈值，第二电阻的投影与第四电阻的投影的中心距离小于或等于第二距离阈值；第一电阻的投影与第二电阻的投影的中心距离大于或等于第三距离阈值，或，第一电阻的投影与第四电阻的投影的中心距离大于或等于第三距离阈值，第三电阻的投影与第二电阻的投影的中心距离大于或等于第四距离阈值，或，第三电阻的投影与第四电阻的投影的中心距离大于或等于第四距离阈值；其中第三距离阈值大于第一距离阈值，第三距离阈值大于第二距离阈值，第四距离阈值大于所述第一距离阈值，第四距离阈值大于第二距离阈值。
在一种可能的设计中，为保证按压前后压敏电阻的变化差异最大化，以提高传感器的灵敏性。第一电阻、第二电阻、第三电阻以及第四电阻采用相同的图形；或者，第一电阻与所述第三电阻采用相同的图形，第二电阻与所述第四电阻采用相同的图形。在以下示例中提供了几种电阻的图形，例如：方式一：压力传感器包括的电阻采用的电阻丝按照正交的方向依次延伸；方式二：压力传感器包括的电阻采用的电阻丝呈螺旋线状；方式三：压力传感器包括的电阻采用直导线段串联形成，其中相邻的直导线段的夹角为固定值。其中，方式二以及方式三提供的电阻的图形共同的特征在于沿着其对称轴(或近似对称轴)及其正交的两个方向上都有较大的分量。压敏电阻采用这种图形时，即使按压点与压力传感器的角度发生变化时也可以保证整体的变化总量接近，可以用来消除按压点与压力传感器的方位关系导致的信号偏差问题，可以消除应变单向敏感性，使各个方向应变趋向均匀。
在一种可能的设计中，非显示区还包括扫描电路；其中压力传感器位于扫描电路远离显示区的一侧。其中由于扫描电路包含晶体管以及电容的元器件，而这些元器件通常需要多层材料层制备，因此扫描电路分设于非显示区的多个层的部分层中。
在一种可能的设计中，显示模组包括至少两个压力传感器，当至少两个压力传感器设置于显示模组的同一边框的非显示区时，至少两个压力传感器中相邻的两个传感器间隔预定间距。该间隔距离可以根据经验设置，例如：需要多个压力传感器共同作用时，其间隔的预定距离应该使得按压范围能够同时触及。
第二方面，提供一种电子设备的控制方法，包括：向压力传感器输入驱动信号，采集压力传感器输出的传感器信号；根据传感器信号生成预定功能的控制信号。由于电子设备采用了第一方面提供的显示模组，因此其解决的技术问题以及实现的技术效果也同第一方面所述，这里不再赘述。
在一种可能的设计中，根据传感器信号生成预定功能的控制信号包括：根据传感器信号确定所述压力传感器的按压时间或按压力度；根据压力传感器的按压时间或按压力度生成预定功能的控制信号。在该方案中，电子设备的控制装置可以根据压力传感器的按压时间或者按压力度生成不同的控制信号，丰富了电子设备的控制形式。
在一种可能的设计中，显示模组包括至少两个压力传感器，且当至少两个压力传感器设置于显示模组的同一边框的非显示区时，至少两个压力传感器中相邻的两个传感器间隔预定间距时；根据传感器信号生成预定功能的控制信号，包括：根据至少两个压力传感器生成的传感器信号生成预定功能的控制信号。在该方案中，电子设备的控制装置可以根据多个压力传感器传感器信号的组合生成不同的控制信号，丰富了电子设备的控制形式。
在一种可能的设计中，向压力传感器输入驱动信号，采集压力传感器输出的传感器信号；之前还包括：确定预定触摸区域的压力传感器，其中预定触摸区域的压力传感器被配置为对应预定功能。该方案将触控屏与本申请的压力传感器结合，预先将不同触摸区域的压力传感器配置为不同的功能，在定位触摸发生的区域后，便可以确定触摸区域压力传感器的功能。
在一种可能的设计中，预定功能包括音量控制功能、电源键功能、快捷键功能；这样，预定功能包括音量控制功能时，根据压力传感器的按压时间或按压力度生成预定功能的控制信号；包括：根据压力传感器的按压时间或按压力度生成控制音量增加或减小的控制信号；预定功能包括电源键功能时，确定压力传感器的按压时间T＜T1时，确定电源键功能为不响应；确定压力传感器的按压时间T1＜T＜T2时，生成休眠信号；确定压力传感器的按压时间T＞T3时，生成关机或重启信号，其中，T1＜T2＜T3；预定功能包括快捷键功能；根据传感器信号生成预定功能的控制信号，包括：根据传感器信号生成调用预定应用的调用信号。
第三方面，提供了一种电子设备的控制装置用于实现上述各种方法。该测试台架的控制装置包括实现上述方法相应的模块、单元、或手段(means)，该模块、单元、或means可以通过硬件实现，软件实现，或者通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块或单元。
第四方面，提供了一种电子设备的控制装置，包括：处理器和存储器；该存储器用于存储计算机指令，当该处理器执行该指令时，以使该电子设备的控制装置执行上述任一方面的方法。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。
其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或” 的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。由此，限定有“第一”、“第二”等的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
此外，本申请中，“上”、“下”、“左”、“右”等方位术语是相对于附图中的部件示意置放的方位来定义的，应当理解到，这些方向性术语是相对的概念，它们用于相对于的描述和澄清，其可以根据附图中部件所放置的方位的变化而相应地发生变化。
在本申请中，除非另有明确的规定和限定，术语“连接”应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或成一体；可以是直接相连，也可以通过中间媒介间接相连。此外，术语“耦接”可以是实现信号传输的电性连接的方式。“耦接”可以是直接的电性连接，也可以通过中间媒介间接电性连接。
随着电子技术的发展，人机交互应用越来越广泛，已逐渐成为人们日常生活必不可少的信息交互媒介。现有电子设备上常见的人机交互项目技术包括：机械按键、触摸感应触摸屏、指纹感应触摸屏和压力感应触摸屏，其中，机械按键通过判断按键按压动作作为交互输入；触摸感应触摸屏则侦测触摸感应，触摸感应触摸屏包括电容触摸屏，电阻触摸屏，超声波触摸屏等；常见指纹触摸感应屏包好电容指纹屏、光学指纹屏等；常见压力感应触摸屏主要采用压电式压力感应元件，即采用压电材料制作压力感应触摸屏，利用压电材料在受到压力时，其电阻会发生变化的原理，通过检测压电材料的电阻或在恒定电流下，检测压电材料的电压来探测压力感应触摸屏受到的压力大小。
通常，在移动电子消费品(例如手机、智能手表等)上侦测按压通常采用机械按键或单独的压力传感器，其中使用的压感技术为外置方案，通过将单独的压力传感器模组置于电子设备中，在用户按压或触摸处时起到交互作用。对于采用机械按键的方式，如图1提供一种现有电子设备01上使用的机械按键的示意图，一般包括电源键、音量键+和音量键-。机械按键有按压发生时，输出端子上的电平发生变化，通过侦测端子电平变化来判断按键是否有按压操作并执行相应动作。对于采用压力传感器的方式，如图2所示提供一种现有电子设备02上使用的压力传感器的示意图，其中电子设备上使用外置的压力传感器，压力传感器为独立制作的压力传感器模组，并使用特定的粘接技术固定在屏幕下方和中框之间。然后再通过柔性电路板(flexible printed  circuit，FPC)将信号端子引出进行信号驱动和接收。
然而，电子设备上使用的机械按键在长期使用的情况下会存在机械磨损的问题，甚至有潜在失效的风险。同时机械按键本身需要占据一定的空间，并且需要突出于整机，不利于实现整机一体化的设计的实现，尤其在瀑布屏移动终端的形态下，机械按键的取消成为必然。虽然外置单独的压力传感器方案可以解决上述问题，但是，由于外置的压力传感器需要在极为有限的空间内使用胶材固定在中框上，在跌落时可能脱落，可靠性风险高；同时组装的差异导致不同整机间的一致性差，还会增加额外的成本。为解决上述技术问题本申请的实施例提供了如下方案，具体说明如下。
本申请实施例提供一种如图3所示的电子设备03。该电子设备03包括例如手表、手机、平板电脑、个人数字助理(personal digital assistant，PDA)、车载电脑、显示器(monitor)和电视(television，TV)等。本申请实施例对上述电子设备03的具体形式不做特殊限制。以下为了方便说明，是以电子设备03为手机为例进行的说明。上述电子设备03结构，如图3所示，主要包括显示模组10、中框11以及壳体12。显示模组10和中框11设置于壳体12内。
如图4所示，显示模组10包括显示区(active area，AA)和位于该AA区周边的非显示区。该AA区包括多个以矩阵形式排列的像素(sub pixel)，也称作像素区。
在本申请的实施例中，上述显示模组10为液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emittingdiode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrixorganic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emittingdiode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot lightemitting diodes，QLED)等等。
此外，如图4所示，显示模组10的非显示区中设置有显示驱动芯片(display driver integrated circuit，DDIC)20。在此情况下，以OLED显示屏为例，同一列像素中的像素电路通过同一条数据线(data line，DL)与DDIC耦接。
如图4所示，上述电子设备03还包括印刷电路板(printed circuit board，PCB)(或者驱动系统板)，以及安装于该PCB上的应用处理器(application processor，AP)(例如CPU)、电源管理芯片(power IC)。图4中的DDIC20通过柔性电路板(flexible printed circuit，FPC)与AP耦接。
这样一来，AP为DDIC和显示模组提供显示数据，用以展示实际的图像信息；power IC为DDIC和显示模组提供工作电压。FPC为PCB和显示模组之间提供信号传输连接路径，FPC与PCB之间通过连接器相连，另外一端FPC通过异向导电膜绑定(bonding)在显示模组上。DDIC负责接收PCB传输的信号并将信号按照特定的时序控制输送给显示模组。例如AP输出的显示数据通过DDIC20后，转换成数据电压Vdata传输至各条数据线DL所耦接的像素的像素电路中。接下来，各个像素电路通过数据线DL上的数据电压Vdata，生成与该数据电压Vdata相匹配的驱动电流I，以驱动像素中的OLED器件发光。
显示模组03中各个像素中的像素电路、OLED器件以及数据线DL等可以制作于一衬底基板上。该衬底基板可以采用柔性树脂材料构成。在此情况下，该OLED显示屏可以作为折叠显示屏。或者，上述OLED显示屏中的衬底基板还可以采用质地较硬的材料， 例如玻璃构成。在此情况下，上述OLED显示屏为硬质显示屏。
此外，如图5所示，以手机作为本申请的电子设备为例进行说明，该手机还可以包括其他部件，当然其仅是一种示例，在一些示例中还可以包括更多或者更少的功能部件。
如图5所示，手机05可以包括处理器510，外部存储器接口520，内部存储器521，传感器模块530，显示模组540等。其中传感器模块530可以包括本申请提供的压力传感器等。
可以理解的是，本发明实施例示意的结构并不构成对手机05的具体限定。在本申请另一些实施例中，手机05可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
处理器510可以包括一个或多个处理单元。例如：处理器510可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processingunit，GPU)，图像信号处理器(image signal processor，ISP)，飞行控制器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)，本申请提供的压力控制器等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
处理器510中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器510中的存储器为高速缓冲存储器。
外部存储器接口520可以用于连接外部存储卡，例如Micro SD卡，实现扩展手机05的存储能力。外部存储卡通过外部存储器接口520与处理器510通信，实现数据存储功能。例如将音乐，视频等文件保存在外部存储卡中。
内部存储器521可以用于存储计算机可执行程序代码，所述可执行程序代码包括指令。内部存储器521可以包括存储程序区和存储数据区。其中，存储程序区可存储操作系统，至少一个功能所需的应用程序(比如声音播放功能，图像播放功能等)等。存储数据区可存储手机05使用过程中所创建的数据(比如音频数据，电话本等)等。此外，内部存储器521可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件，闪存器件，通用闪存存储器(universal flash storage，UFS)等。处理器510通过运行存储在内部存储器521的指令，和/或存储在设置于处理器中的存储器的指令，执行手机05的各种功能应用以及数据处理。
在一些实施例中，处理器510可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuitsound，I2C)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purposeinput/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。处理器510可以通过I2C接口耦合压力传感器，以实施本申请提供的电子设备的控制方法。
手机05通过GPU，显示模组540，以及应用处理器等实现显示功能。GPU为图像处理的微处理器，连接显示模组540和应用处理器。GPU用于执行数学和几何计算，用于图形渲染。处理器510可包括一个或多个GPU，其执行程序指令以生成或改变显示信息。
显示模组540用于显示图像，视频等。显示模组540可以采用液晶显示屏(liquid crystal display，LCD)，有机发光二极管(organic light-emittingdiode，OLED)，有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrixorganic light emitting diode的，AMOLED)，柔性发光二极管(flex light-emittingdiode，FLED)，Miniled，MicroLed，Micro-oLed，量子点发光二极管(quantum dot lightemitting diodes，QLED)等。在一些实施例中，手机05可以包括1个或N个显示模组540，N为大于1的正整数。
压力传感器用于感受压力信号，可以将压力信号转换成电信号。在一些实施例中，可以通过压力传感器确定用户施加的按压，进而方便手机05对该操作对应的控制指令进行响应。
传感器模块530还可以包括触摸传感器，也称“触控器件”。触摸传感器(也称为触控面板)可以设置于显示模组540，由触摸传感器与显示模组540组成触摸屏，也称“触控屏”。触摸传感器用于检测作用于其上或附近的触摸操作。触摸传感器可以将检测到的触摸操作传递给应用处理器，以确定触控事件类型。可以通过显示模组540提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器也可以设置于手机05的表面，与显示模组540所处的位置不同。
以下结合图6具体介绍本申请实施例提供的显示模组。以下实施例中的显示模组均可以在具有上述硬件结构的终端或者具有类似结构的终端中实现。
本申请实施例中的基本原理是：在显示模组的非显示区设置压力传感器，其中形成压力传感器的压敏电阻与显示区的半导体材料层同层设置，且压敏电阻采用与半导体有源层相同的材料制作。
具体的参照图6所示，本申请的实施例提供的显示模组包括：包括显示区AA和非显示区；其中非显示区包括一个或多个压力传感器；且至少一个敏电阻与显示区的半导体有源层同层设置，且至少一个压敏电阻采用与半导体有源层相同的材料制作。
需要说明的是，如图6所示，显示区AA为显示模组的实际成像发光区，是显示模组展示图像的区域；显示区AA的数据信号线为显示区AA提供图像信号，数据信号线一端连接显示区AA的像素的像素电路，另外一端通过信号端子连接到驱动IC；非显示区的扫描电路为显示区AA提供图像显示需要的扫描信号，扫描电路提供的扫描信号与数据信号线所提供的图像信号一起作为显示区AA的输入信号，驱动显示区AA的像素电路进行图像显示；扫描电路信号线为扫描电路工作提供需要的输入信号来驱动扫描电路工作，扫描电路信号线一端连接扫描电路，另外一端通过信号端子连接到驱动IC；压力传感器设置在非显示区，通常在显示模组上，为了便于操作，压力传感器一般处于屏幕左右两侧的边框区域，也可以摆放在屏幕上下的边框区域；示例性的，压力传感器位于扫描电路远离显示区AA的一侧。其中由于扫描电路包含晶体管以及电容的元器件，而这些元器件通常需要多层材料层制备，因此扫描电路分设于非显示区的 多个层的部分层中。在显示模组的边框区域可以分布多组压力传感器，每组压力传感器对应于不同的功能，且每组压力传感器可以包含一个或多个压力传感器，如图7所示，功能1的压力传感器(组)、功能2的压力传感器(组)、…功能n的压力传感器(组)等。压力传感器可以通过侦测外部压力的变化并反馈到处理器并由处理器来执行相应的功能和交互界面；如图6所示，压力传感器通过压力传感器信号线连接至驱动IC，驱动IC通过压力传感器信号线为压力传感器提供驱动信号并且接收压力传感器输出的信号。其中，数据信号线、扫描电路信号线、压力传感器信号线可以通过一定的走线和封装处理后通过信号端子连接至驱动IC，以将信号传递至驱动IC。驱动IC为显示模组的显示区AA、扫描电路、以及压力传感器提供工作所需要的信号并且接收其反馈信号，针对上述显示区AA、扫描电路、以及压力传感器驱动IC可以为多颗分离式的驱动IC，也可以为一颗集成式的IC；以分离式的驱动IC为例，驱动IC可以包括：DDIC、扫描电路驱动IC以及压力控制器，其中显示区AA的像素电路通过数据信号线耦接DDIC、扫描电路通过扫描电路信号线耦接扫描电路驱动IC，压力传感器通过压力传感器信号线耦接压力控制器。
此外，在一些示例中，如图8所示，显示模组的层叠结构自上而下包括偏振层(polarizer)71、薄膜封装层(thin-film encapsulation,TFE)72、前面板(frontplane)73、底板(backplane)74、以及基板(backside barrier)75。其中，偏振层(polarizer)71包括反射膜侧粘着剂层(adhesive)、偏振片(polarizer，POL)以及剥离膜侧粘着剂层(adhesive)等；薄膜封装层72自上而下包括：氮化硅层SiNx或氧化硅层SiOx、有机树脂层organic/resin、氮化硅层SiNx或氧化硅层SiOx；前面板(frontplane)73自上而下包括：阴极层(cathode)、电子传输层(electron transport layer，ETL)、空穴阻挡层(hole block layer，HBL)、发光层(emission layer，EL)、空穴传输层(hole tranport layer，HTL)、空穴注入层(hole injection layer，HIL)、阳极层(anode)；底板(backplane)74自上而下包括：平坦化层(planarizationlayer，PLN)/薄膜晶体管(thin film transistor，TFT)器件层、基底(substrate)；基板(backside barrier)75自上而下包括：氮化硅层SiNx或氧化硅层SiOx、有机树脂层organic/resin、氮化硅层SiNx或氧化硅层SiOx。以上只是OLED屏幕为例进行说明，当采用LCD屏幕时，TFT器件通常设置在阵列基板中，此处不再赘述。其中TFT器件层包括半导体有源层、多层导线层以及多层绝缘层。
如图9所示，提供了一种典型的TFT器件层75的结构，其包括栅极751由位于最下层的导电层制作形成、栅极751上方覆盖栅极绝缘层752、栅极绝缘层752上方对应栅极751的位置覆盖有半导体有源层753、半导体有源层753的上方形成源极754和漏极755，其中源极754和漏极755之间形成有沟道，源极754和漏极755由同层的导电层制作形成；源极754和漏极755上方覆盖有钝化绝缘层756，其中钝化绝缘层756上方制作像素电极层76以及其他膜层77。上述的导电层的材料可以使用金属材料，例如铜或者其他导电材料，例如石墨烯等等；像素电极层76可以使用氧化铟锡ITO等透明导电材料；半导体有源层可以使用硅Si、金属氧化物等材料。本申请的预定材料层包括半导体有源层，压力传感器包括至少一个压敏电阻78与半导体有源层同层。上述图8是以一种底栅型TFT的层叠结构为例，可以理解的是还有其他类型例如 顶栅型、双栅型TFT。在使用其他类型的TFT时，由于TFT均包含半导体有源层，因此本申请提供的压力传感器中的压敏电阻均可以与半导体有源层同层制备。由于半导体有源层具有压敏特性，即受到压力按压后改变电阻的特性，因此压力传感器的全部压敏电阻位于显示模组的半导体有源层。这样可以在制作显示模组的各材料层的同时将压力传感器的压敏电阻与显示区的多个压敏电阻，且至少一个所述压敏电阻与所述显示区的半导体有源层采用相同的材料同层制作，节省了空间，由于无需使用胶材固定，而是在显示模组的制程工艺中同步形成，提高了产品的整体性和可靠性。
根据压力传感器的电路设计需求，压力传感器中还可以包括除压敏电阻以外的其他电阻，可以理解的是，压力传感器中至少具有一个上述的压敏电阻时，即可实现压力传感器的功能。其他电阻与显示模组中除半导体有源层外的其他材料层同层。例如导线层、像素电极层或其他功能导电层(如OLED屏中，OLED的阳极层、阴极层等)；其中导线层可以是上述方案中形成栅极、源极、漏极、数据信号线、扫描电路信号线、压力传感器信号线等的导电层；以上述图7、图8为例，采用OLED的显示模组以及底栅型TFT时，半导体有源层位于与栅极同层的栅线(扫描电路输出的信号线)上方，半导体有源层位于与源漏极同层的数据信号线的下方，半导体有源层位于像素电极层，例如：阴极层、阳极层下方。
参照图10所示，压力传感器包括四个电阻R1-R4，第一电阻R1的第一端耦接第四电阻R4的第二端，第一电阻R1的第二端耦接第二电阻R2的第一端；第二电阻R2的第二端耦接第三电阻R3的第一端，第三电阻R3的第二端耦接第四电阻R4的第一端；第一电阻R1的第一端、第二电阻R2的第一端、第三电阻R3的第一端以及第四电阻R4的第一端分别通过导线耦接压力控制器，其中压力控制器用于向第一电阻R1的第一端输出入第一电压信号、向第三电阻R3的第一端输入第二电压信号；接收第二电阻R2的第一端输出的第三电压信号、接收第四电阻R4的第一端输出的第四电压信号，根据第三电压信号和第四电压信号获取压力传感器的电阻变化量，并根据压力传感器的电阻变化量计算压力传感器被施加的压力。四个电阻(R1\R2\R3\R4)首尾相连，每个电阻与相邻的两个电阻各形成一个节点，总共四个节点a、b、c、d；共有两个节点a、b输入信号，两个节点c、d输出信号；相对的两个节点(不相邻的两个节点)作为两个输入信号的连接端子，另外一组相对的两个节点作为两个输出信号的连接端子。
其中，四个电阻满足如下关系：R1/R2＝R4/R3；R1为第一电阻的阻值，R2为第二电阻的阻值，R3为第三电阻的阻值，R4为第四电阻的阻值。
压力控制器向第一电阻R1的第一端输出入第一电压信号、向第三电阻R3的第一端输入第二电压信号；并接收第二电阻R2的第一端输出的第三电压信号、接收第四电阻R4的第一端输出的第四电压信号，并且通过侦测两个输出信号(第三电压信号、第四电压信号)来判别电阻的变化。其中压敏电阻的变化值与压力呈一定的关系，例如Si电阻在收到外界压力时，电阻的变化值与压力呈正比关系，即δR＝kF；其中，δR为电阻变化量，F为压力，k为电阻变化量与压力之间的系数。当压力变化时，电阻变化不同，压力传感器输出信号也随之发生改变；可以通过侦测压力传感器的两个输出信号的变化计算出压力的大小。
为了提高传感器输出信号的幅度，以提高传感器的灵敏性，示出了一种压力传感 器的各个压敏电阻的摆放位置。其中第一电阻R1、第二电阻R2、第三电阻R3以及第四电阻R4在显示模组表面所在平面的投影中，第一电阻R1的投影与第三电阻R3的投影的中心距离小于或等于第一距离阈值，第二电阻R2的投影与第四电阻R4的投影的中心距离小于或等于第二距离阈值；第一电阻R1的投影与第二电阻R2的投影的中心距离大于或等于第三距离阈值，或第一电阻R1的投影与第四电阻R4的投影的中心距离大于或等于第三距离阈值，第三电阻R3的投影与第二电阻R2的投影的中心距离大于或等于第四距离阈值，或第三电阻R3的投影与第四电阻R4的投影的中心距离大于或等于第四距离阈值；其中第三距离阈值大于第一距离阈值，第三距离阈值大于第二距离阈值，第四距离阈值大于第一距离阈值，第四距离阈值大于第二距离阈值。
示例性的，如图11所示，压力传感器的四个电阻按照走线连接关系分为相邻和相对；相邻的两个电阻直接由电阻小的导线层或像素电极层形成的导线连接，如R1分别与R2和R4相邻；相对的两个电阻之间没有直接的连接关系，如R1和R3相对，R2和R4相对；按照相对关系将四个电阻分为两组，R1和R3一组，R2和R4一组，在压力传感器内部各个电阻之间的摆放关系为：相对的电阻内部两个电阻摆放靠近，而这两组相对电阻之间则摆放远离；例如：相对电阻R1和R3之间距离为L1，相对电阻R2和R4之间距离为L2，两组相对电阻组之间距离为L3，则有L1与L2相等或近似，L3则大于L1和L2。压力传感器的四个电阻在同一受力点的作用下电阻变化不一致，在设计上将相对的电阻内部两个电阻摆放靠近，而这两组相对电阻之间则摆放远离可以将电阻间的电阻变化差异最大化，增强信号灵敏度。此外，显示模组包括至少两个压力传感器，当至少两个压力传感器设置于显示模组的同一边框的非显示区时，至少两个压力传感器中相邻的两个传感器间隔预定间距。该间隔距离可以根据经验设置，例如：需要多个压力传感器共同作用时，其间隔的预定距离应该使得按压范围能够同时触及。参照图12所示，在一种示例中，示出了一种显示模组的尺寸，其中，显示模组长度L4为150mm,显示模组宽度W1为75mm,非显示区域(如图所示右侧边框区域)宽度W2为2mm；在显示模组左右两侧的边框区域中自上而下各分布多个压力传感器(例如可以是4个)，压力传感器之间的间距Z为10mm,压力传感器宽度y为100um,压力传感器的长度x为400um。
此外，本申请对压力传感器中的电阻的形式不作限定，参照图13-图17提供了几种典型的电阻的图形。
如图13所示，电阻采用的电阻丝按照正交的方向依次延伸。电阻图形1为正交式的电阻图案设计，电阻的图案设计中电阻丝的走线按照正交的两个方向依次延伸而成。压敏电阻采用这种图形时，由于按压点与压力传感器存在一定的角度关系，所以存在当每次按压点与压力传感器的方位关系不一致时会出现压力传感器输出信号之间存在压差。图14-图16电阻采用的电阻丝呈螺旋线状。具体的，图14所示的电阻图形2为正多边形或类(近似)正多边形(图示为正八边形，其他正多边形或类(近似)正多边形也包含在内)。电阻图形由多圈电阻丝由内而外依次连接而成，内圈至外圈的每一段直线电阻丝的长度呈现内圈小外圈大且两段直线电阻丝之间角度(60°～180°)固定。图15所示的电阻图形3为圆形或类(近似)圆形。电阻图形由多圈电阻丝由内而外依次连接而成，内圈至外圈的每一段弧形电阻丝的半径呈现内圈小外圈大。图16 所示的电阻图形4为椭圆形或类(近似)椭圆形。电阻图形由多圈电阻丝由内而外依次连接而成，内圈至外圈的每一段电阻丝呈现椭圆的弧形，且椭圆弧形的弧长呈现内圈小外圈大。图17所示的电阻采用直导线段串联形成，其中相邻的直导线段的夹角为固定值。具体的，电阻图形5为多段直线电阻丝以固定的角度依次连接而成(角度介于0～90°)。其中，电阻图形2～电阻图形5共同的特征在于沿着其对称轴(或近似对称轴)及其正交的两个方向上都有较大的分量。压敏电阻采用这种图形时，即使按压点与压力传感器的角度发生变化时也可以保证整体的变化总量接近，可以用来消除按压点与压力传感器的方位关系导致的信号偏差问题，可以消除应变单向敏感性，使各个方向应变趋向均匀。
此外，第一电阻、第二电阻、第三电阻以及第四电阻采用相同的图形；或者，第一电阻与第三电阻采用相同的图形，第二电阻与所述第四电阻采用相同的图形。如图18所示，R1-R4均采用电阻图形1，当然R1-R4也可以全部采用其他任意一项电阻图形。如图19-图24，其中R1与R3采用同一种电阻图形，R2-R4采用同一组电阻图形，以上附图仅是示例。除此之外上述电阻图形之间的其他组合也在本发明的保护范围之内。此外需要说明的是，以上对于相对的电阻，例如电阻R1与R3、R2与R4仅限定两者之间的电阻图形相同，可以理解的是这样做可以保证按压前后电阻变化差异的最大化，以提高发生按压时传感器的灵敏性。本申请并不限定相对的电阻之间角度的差异，例如，R1的电阻图形可以时相对R3的电阻图形旋转一定角度后的电阻图形。如图24中，R2的电阻图形为R4的电阻图形旋转180°的电阻图形。
本申请的实施例还提供一种电子设备的控制方法，该电子设备包含上述的显示模组，包括如下步骤：
101、向压力传感器输入驱动信号，采集压力传感器输出的传感器信号。
102、根据传感器信号生成预定功能的控制信号。
根据上述实施例的描述，由于压力控制器能够向压力传感器输入驱动信号，并且接收压力传感器输出的传感器信号，因此当压力传感器受到按压时，可以根据此时的传感器信号确定压力传感器被按压，进而生成预定功能的控制信号。例如，每个压力传感器被预先配置为控制一个功能，或者多个压力传感器联合被配置为控制一个功能。则当压力传感器被按压时，可以根据压力传感器生成的传感器信号生成预定功能的控制信号，控制该功能进行对应的操作。步骤102具体包括：根据传感器信号确定压力传感器的按压时间或按压力度；根据压力传感器的按压时间或按压力度生成预定功能的控制信号。例如，当侦测到有按压发生时由压力控制器通过读取各压力传感器的输出的传感器信号来判断哪一功能模块对应压力传感器并且通过按照有按压时间长短或者按照按压力度的大小来执行对应功能。例如：若对应的功能模块需要划分为多阶(如音量调整操作、亮度调整操作等)，则需要对应的将按压力度分成多阶或将按压时间分成多阶，并将受力的分阶或按压时间的分阶与对应功能的分阶建立映射关系和查找表。在该方案中，电子设备的控制装置可以根据压力传感器的按压时间或者按压力度生成不同的控制信号，丰富了电子设备的控制形式。如图25所示，当确定压力传感器被按压时，在n个压力传感器中确定被按压传感器对应的预定功能，根据传感器信号生成该预定功能的控制信号，例如，根据压力传感器的按压时间或按压力度生成预定 功能的控制信号，对预定功能进行控制。例如：预定功能包括音量控制功能；根据压力传感器的按压时间或按压力度生成控制音量增加或减小的控制信号。预定功能包括电源键功能；在确定压力传感器的按压时间T＜T1时，确定电源键功能为不响应；确定压力传感器的按压时间T1＜T＜T2时，生成休眠信号；确定压力传感器的按压时间T＞T3时，生成关机或重启信号，其中，T1＜T2＜T3。预定功能包括快捷键功能；根据传感器信号生成调用预定应用的调用信号。
在另一个示例中，当显示模组与触摸屏结合时，显示模组上设置有触控装置，或者显示模组中集成有触控功能膜层，此时可以通过触摸屏的定位方式确定按压发生的部位是否落在非显示区域具有压力传感器的区域，然后根据按压落在区域对应的压力传感器执行相应的功能。此时该方法还包括：确定预定触摸区域的压力传感器，其中预定触摸区域的压力传感器被配置为对应预定功能。若预定触摸区域没有压力传感器，则执行触摸相关功能。参照图26所示，首先，确定预定触摸区域；然后，确定预定触摸区域具有压力传感器；当确定压力传感器被按压时，确定被按压传感器对应的预定功能，根据传感器信号生成该预定功能的控制信号，例如，根据压力传感器的按压时间和/或按压力度生成预定功能的控制信号，对预定功能进行控制。如图26所示，压力传感器的功能包括音量加(增加)、音量减(减小)、电源键功能、快捷键功能(例如快速调用APP功能)以及其他对应的功能，其中在电源键功能的压力传感器的侦测以及执行中可以根据侦测按压时间长短来判别休眠、关机或重启，例如按压时间T＜T1时，确定电源键功能为不响应；按压时间T1＜T＜T2时，确定电源键功能为休眠；按压时间T＞T3时，确定电源键功能为关机或重启，其中，T1＜T2＜T3。
在另一种示例中，步骤102具体可以为根据至少两个压力传感器生成的所述传感器信号生成预定功能的控制信号。在该方案中，电子设备的控制装置可以根据多个压力传感器传感器信号的组合生成不同的控制信号，丰富了电子设备的控制形式。具体为：压力控制器可以侦测多组压力传感器的输出信号之间的关系来判断操作媒介(手指等)滑动方向。如图27所示，当确定多个压力传感器被按压时，根据压力传感器生成的传感器信号确定操作媒介(手指等)滑动方向；根据滑动方向来执行相应的功能；如可以在通过压力传感器判断滑动方向向上或向下来执行音量是增加或减小。当然，以上仅仅是提供了一种根据多个压力传感器的输出信号来判断滑动方向的示例，可以理解的是也可以有其他根据传感器信号生成预定功能的控制信号的方式，例如侦测到两个特定传感器同时输出传感器信号超过预定时长时，生成执行截屏、关机等功能。以下结合图28对本申请通过侦测多个压力传感器输出信号来判断滑动方向的具体方式进行说明如下。
压力传感器在显示模组的边框区域按照压力传感器1、压力传感器2、……、压力传感器n-1、压力传感器n的自上而下的顺序排列；手指在压力传感器附近滑动时，sensor输出与手指离压力传感器的长度在数学上呈现反相关；手指按压点在压力传感器中间时，压力传感器输出量最大；手指按压点远离压力传感器时，压力传感器输出量变小；当手指在显示模组的边框区域上单向滑动时，记录各个时间点各个压力传感器的输出，通过各个压力传感器输出的传感器信号的峰值的时间和压力传感器间信号的相对大小可以判别手指滑动方向；记各压力传感器1～压力传感器n峰值点出现 时间点位T1～Tn,若T1<T2<……<Tn,则判定为下滑，如图29所示；若T1>T2>……>Tn,则判定为上滑，如图30所示。另一种情况是，根据两个时刻(T0、T1)各个压力传感器的输出值，选择T0时刻输出值最大的两个压力传感器记为压力传感器m和压力传感器m+1(1≤m≤n),其对应的输出值记为S[m,T0]和S[m+1,T0],再记录下一个侦测时间点T1时刻其对应的输出S[m,T1]和S[m+1,T1],若S[m,T0]>S[m,T1]且S[m+1,T0]<S[m+1,T1]；或S[m,T0]<S[m,T1]且S[m+1,T0]<S[m+1,T1]且S[m,T0]>S[m+1,T0]；或S[m,T0]>S[m,T1]且S[m+1,T0]>S[m+1,T1]且S[m,T0]<S[m+1,T0]；则为下滑；反之则为上滑；压力传感器按照其他方式排列或者在其他区域排列，判别方式一致，滑动趋势则依照对应压力传感器排列的相互关系确定。
