具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开实施例提供了一种压力检测装置100，如图1所示，包括：电容检测模块14以及设置在衬底基板10上的第一电极11、第二电极12以及绝缘层13，其中，绝缘层13由弹性材料制成并且位于第一电极11和第二电极12之间；第一电极11和第二电极12位置相对，即第一电极11和第二电极12交叠设置，电容检测模块14分别与第一电极11和第二电极12连接，用于检测第一电极11和第二电极12之间的电容。图1中以第一电极11、第二电极12、绝缘层13设置在衬底基板10上为例进行说明。
需要说明的是，绝缘层由弹性材料制成，即绝缘层在受到压力作用下能够发生形变(例如厚度减小)且在压力去除后可恢复原来形状。例如，绝缘层可以是PET(聚对苯二甲酸乙二酯)薄膜。由电容的计算公式可知，第一电极和第二电极的电容与第一电极和第二电极的距离成反比，因此，压力越大，绝缘层形变越大，第一电极和第二电极的距离越近，第一电极和第二电极之间的电容越大；反之，压力越小，绝缘层的形变越小，第一电极和第二电极的距离越远，第一电极和第二电极之间的电容越小。电容检测模块检测第一电极和第二电极之间的电容，则该电容的大小可以反映出压力的大小，即可以检测压力的大小变化。
例如，在本公开的实施例中，电容检测模块通过连接线分别与第一电极和第二电极连接，本公开的实施例不对电容检测模块的位置进行具体限定。例如，如图1所示的第一电极11、第二电极12以及绝缘层13设置在衬底基板10的同一侧，电容检测模块14可以设置在衬底基板10的另一侧，且分别 与第一电极11和第二电极12连接。或者，压力检测装置还包括电路绑定区域，该线路绑定区域专用于绑定线路板等，电容检测模块设置在该电路绑定区域。该电容检测模块可以是电容检测电路，可以包括晶体管、放大器、电阻等器件。例如，该电容检测电路将激励信号输入待测电容，并测量该待测电容电压的变化，进而检测出该待测电容的电容值。
本公开实施例提供的一种压力检测装置，第一电极和第二电极之间设置有绝缘的弹性材料层，弹性材料在压力的作用下发生压缩形变，第一电极和第二电极的距离减小，压力越大，第一电极和第二电极的距离越小，电容越大；压力越小，第一电极和第二电极的距离越大，电容越小，从而可以通过检测电容的大小确定压力的大小。
例如，压力检测装置中的第一电极、第二电极以及绝缘层可以采用透明或者不透明材料形成，但若压力检测装置应用于显示装置，则本公开实施例中压力检测装置中的第一电极、第二电极以及绝缘层均采用透明材料形成，例如，第一电极和第二电极由透明导电材料制成，例如ITO(铟锡氧化物)。
例如，压力检测装置检测第一电极和第二电极之间的电容，则第一电极和第二电极的形状可以是具有交叠区域的任意形状，例如第一电极是面状电极、第二电极也是面状电极，或者，第一电极是条状电极、第二电极是面状电极等。
例如，第一电极和第二电极的交叠区域呈矩阵(例如，多点阵列)排布。第一电极和第二电极在交叠区域处形成电容，第一电极和第二电极的交叠区域呈矩阵排布，则在检测第一电极和第二电极的电容时，还可以确定压力(例如，触摸产生的压力)作用的位置。
下面列举几种第一电极和第二电极的相对位置呈矩阵排布的情况。
实施例一：
例如，第一电极包括多个呈矩阵或阵列排布且彼此绝缘(例如，互不接触)的块状电极，第二电极为面状电极并与第一电极对应。或者，第二电极包括多个矩阵或阵列排布且彼此绝缘(例如，互不接触)的块状电极，第一电极为面状电极并与第二电极对应。
例如，如图2所示，以第一电极11包括多个呈矩阵或阵列排布且互不接触的块状电极，第二电极12为面状电极并与第一电极11对应为例进行说明。 如图2所示，每个第一电极中的块状电极具有二维(x,y)位置坐标(例如，以每个第一电极中的块状电极中心位置的坐标作为位置坐标)，则通过例如逐个或逐行扫描的方式电容检测模块不仅可以获取第一电极和第二电极之间的电容值以确定压力大小，还可以通过电容检测模块或其他电路模块获取第一电极的位置坐标，以确定触摸位置。
或者，例如，第二电极包括多个阵列排布且互不接触的块状电极，第一电极为面状电极并与第二电极对应。具体可以参照上述第一电极为多个阵列排布且互不接触的块状，第二电极为面状的描述，二电极为多个阵列排布且互不接触的块状而第一电极为面状的情况下，其确定触摸位置的原理与上述相同，在此不作赘述。
实施例二：
例如，如图3所示，第一电极11包括多个沿x轴平行排列(即与y轴平行)的条状电极，第二电极12包括多个沿y轴平行排列(即与x轴平行)的条状电极，第一电极11和第二电极12部分交叠，在交叠区域，第一电极11和第二电极12相对设置，第一电极11和第二电极12的交叠区域呈矩阵或多点阵列排布。如图3所示，则第一电极可以确定触摸位置的x轴坐标，第二电极可以确定触摸位置的y轴坐标，因此，通过电容检测模块不仅可以获取第一电极和第二电极形成电容值以确定压力大小，还可以通过电容检测模块或其他电路模块确定触摸位置。
例如，第一电极和第二电极交叠可以是如图3所示的第一电极11和第二电极12相互垂直，也可以是第一电极和第二电极为具有任意夹角(例如夹角大于零)交叠。
需要说明的是，第一电极和第二电极的交叠区域呈矩阵或多点阵列排布也不局限于上述方式，本公开实施例仅以上述为例进行说明。
例如，绝缘层包括多个互不接触的绝缘图案，绝缘图案位于第一电极和第二电极的交叠区域。
例如，以图2为例，相对于图1所示的截面示意图，图4所示的截面示意图中绝缘层包括绝缘图案131，第一电极11包括矩阵或阵列排布且互不接触的块状电极，第二电极12为面状电极，绝缘图案131位于第一电极11的下面，例如第一电极11的下面是指第一电极面对第二电极的一侧。从而可以 消除弹性材料层的边缘的刻蚀痕迹，消除了对显示的影响。
本公开实施例提供了一种光栅300，如图5所示，包括：光栅盒200以及设置在光栅盒200上的压力检测装置100。
例如，光栅300不仅包括上述光栅盒200和压力检测装置100，其还包括驱动光栅盒形成光栅的驱动电路等，由于驱动光栅盒(例如光栅盒中的液晶)的驱动电路等与本公开的发明不直接相关，本公开实施例仅示例出与本公开的发明相关的结构。而电容检测模块可以是集成设置在光栅的驱动电路上，也可以是单独设置在光栅的其他位置，本公开实施例对其具体位置不作限定。因此，图5仅列出了各层电极之间的层级设置关系，未示出压力检测装置的电容检测模块。
例如，本公开实施例提供的光栅，不仅可以形成光栅条纹，还可以检测压力大小，且在压力检测装置的第一电极和第二电极的相对位置呈矩阵或多点阵列排布时还可以进一步检测触控位置。该光栅可应用于3D显示面板，则显示装置可以是根据用户施加压力的大小调整显示参数，以提高用户体验。
例如，如图5所示，光栅盒200包括：对盒的第一基板21和第二基板22；
例如，第一电极11、绝缘层13、第二电极12设置于第一基板21远离第二基板22的一侧，第一基板21靠近第二基板22的一侧设置有第三电极31，第二基板22靠近第一基板21的一侧设置有第四电极41，第三电极31和第四电极41用于形成光栅。图5中以光栅盒200为液晶光栅为例进行说明，则第三电极31和第四电极41之间还设置有液晶30。液晶光栅的形成原理为：当向第三电极31和第四电极41加载电压时，液晶30在电场的驱动下发生偏转，通过控制向第三电极31和第四电极41加载电压的大小，控制液晶30的偏转角度，以形成光栅。以图5所示的光栅盒200为例，在第三电极31和第四电极41不形成电场的情况下，光栅可以为完全透光，则在第三电极31和第四电极41加载电压，在第三电极31和第四电极41的相对位置处或交叠区域的液晶30偏转不透光，相邻的两个第四电极41之间的位置处液晶30不发生偏转依然透光，从而可以形成明暗相间的条纹。
例如，如图5所示的光栅，第三电极31和第四电极41形成光栅。第三电极为条状电极，第四电极为面状电极并与多个第三电极对应；或者，第三 电极为条状电极，第四电极为条状电极，第三电极与第四电极位置对应；或者，若第三电极为面状电极，则第四电极为条状电极，第三电极与多个第四电极对应。即第三电极和/或第四电极为条状电极，以能够实现光栅。图5中以第三电极31为面状电极，第四电极41为条状电极为例进行说明。
或者，例如，如图6所示，光栅盒200包括：对盒的第一基板21和第二基板22；
例如，第一电极11和绝缘层13设置于第一基板21远离第二基板22的一侧，第二电极12设置于第一基板21靠近第二基板22的一侧，第二基板22靠近第一基板21的一侧设置有第四电极41，第二电极12和第四电极41用于形成光栅。图6中以光栅盒200为液晶光栅为例进行说明，则第二电极12和第四电极41之间还设置有液晶30。即图6所示的光栅300中，第二电极12不仅用于与第一电极11形成电容，以便于检测压力的大小；第二电极12还用于与第四电极41形成光栅。相对于图5所示的光栅，减少了一层图层，简化了制作工艺、降低了生产成本。
例如，如图6所示的光栅，第二电极12和第四电极41形成光栅。第二电极为条状电极，第四电极为面状电极并与多个第二电极对应；或者，第二电极为条状电极，第四电极为条状电极，第二电极与第四电极位置对应；或者，第二电极为面状电极，第四电极为条状电极，第二电极与多个第四电极对应。即第二电极和/或第四电极为条状，以能够实现光栅。图6中仅以第二电极为面状，则第四电极41为条状为例进行说明。
需要说明的是，图6中的液晶光栅的形成原理与图5中相同，在这里不作赘述。当然，光栅盒也不局限与图5、图6所示的液晶光栅，例如图5、图6中的液晶还可以由电致变色材料层替换，电致变色材料在没有电场的区域或位置处透光，在有电场的区域或位置处颜色发生变化而不透光，从而形成光栅。
例如，图5、图6中，第一电极11、第二电极12以及绝缘层13均形成在第一基板21上，则第一基板21相当于图1、图4中的衬底基板10。
本发明实施例的光栅不限于上述液晶光栅，还可以为其他类型的光栅。例如，如图7A所示，光栅300’包括衬底基板10，在衬底基板10的一侧上形成通过不透光材料形成光栅条纹50，该不透光材料可以为金属材料、金属 氧化物材料、树脂材料等。当在该光栅300’上形成根据本发明实施例的压力检测装置时，压力检测装置可以与光栅条纹形成在衬底基板的不同侧上，如图7A所示，压力检测装置的第一电极11、第二电极12和绝缘层13位于衬底基板10上；或者，如图7B所示，压力检测装置的第一电极11和绝缘层13位于衬底基板10上与光栅条纹50的不同侧上，而压力检测装置的第二电极12位于衬底基板上与光栅条纹50的相同侧上。
例如，本公开实施例提供了一种显示装置400，如图8所示，显示装置400包括显示面板500以及位于显示面板500出光侧的本公开任一实施例提供的光栅300。
需要说明的是，若光栅仅可以检测压力大小而不能检测触控位置，则显示装置还可以进一步包括触摸面板，以检测触控位置。若光栅不仅可以检测压力大小，还可以检测触控位置，则显示装置中无需再设置触摸面板。
本公开实施例提供的一种显示装置，光栅可以实现3D显示，且还可以进一步检测压力大小，以及触控位置，可以将压力大小应用于触控中，例如，可以根据压力的大小调整显示画面的色彩、饱和度，或者根据压力的大小设置显示比例等，这样，用户施加的压力大小将影响显示装置的显示效果，以提高用户体验。
该显示装置除上述光栅之外，还包括显示面板，该光栅设置在显示面板的显示侧以与显示面板合作实现3D显示。例如该显示面板可以为液晶显示面板、有机发光二极管显示面板、电子纸显示面板等。当光栅采用液晶光栅时，显示装置可以方便地实现2D显示与3D显示的切换。
例如，显示装置还包括电路绑定区域，该区域设置有驱动显示面板显示的驱动芯片等，本公开实施例中压力检测装置的电容检测模块例如集成在该电路绑定区域。
本公开实施例提供了一种显示装置的显示方法，包括：
步骤101、获取电容检测模块检测的第一电极和第二电极之间的电容值以及触控位置。
其中，获取电容值以及触控位置可以是通过本公开实施例提供的压力检测装置获取，还可以是通过压力检测装置获取电容检测模块的电容值，通过触控面板获取触控位置。
步骤102、根据电容值和触控位置调节显示装置的显示参数和/或显示装置的音量。例如，显示参数可以是显示亮度、颜色、色彩饱和度、显示比例等。例如，可以根据压力的大小调整显示画面的颜色，这样，用户施加的压力大小将影响显示装置的显示效果，以提高用户体验。
例如，在显示装置应用于进行绘图等操作中，触控的位置以及压力大小对绘图效果产生的影响。如图9所示，可以设置压力小画笔较细，压力大画笔较粗。
例如，在形成触控路径的过程中，获取触控路径上每个触控位置处第一电极和第二电极之间的电容值，根据该触控位置处的电容值调节对应于该触控位置的画笔大小。以显示装置为画板为例进行说明，用户利用显示装置进行书法练习时，可以通过控制压力大小以调整笔画粗细，参照图10所示，从左至右压力变大则笔画变粗。或者，在进行书法练习时，参照图10所示，还可以是从左至右压力变大墨水浓度越高等。这样使得用户在显示装置上实现书法的联系更接近于实际的着笔练习，提高用户体验。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
本专利申请要求于2015年10月30日递交的中国专利申请第201510729202.4号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
