具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本发明实施例提供一种自发电式触控面板01，如图1所示，包括盖板24，以及设置于所述盖板24上异层设置的触控感应电极10和触控驱动电极11，该触控感应电极10相对于触控驱动电极11而言，更靠近盖板24。其中，触控感应电极10和触控驱动电极11之间设置有弹性部件层，所述弹性部件层包括相互间隔开的多个弹性部件12。
此外，该自发电式触控面板还可以包括透明摩擦层13，透明摩擦层13的一 侧表面与触控感应电极10相接触，另一侧表面与弹性部件12相接触。
需要说明的是，为了提高触控显示面板的触控感应灵敏度，构成上述盖板24的材料可以是介电常数为3.5-3.7的玻璃或树脂材料。
本发明实施例提供的自发电式触控面板，包括盖板以及设置于所述盖板异层设置的触控感应电极和触控驱动电极，触控感应电极相对于触控驱动电极，靠近盖板。触控感应电极和触控驱动电极之间设置有弹性部件。此外该自发电式触控面板还包括透明摩擦层，该透明摩擦层的一侧表面与触控感应电极相接触，另一侧表面与弹性部件相接触。这样一来，在触控的过程中，当手指与自发电式触控面板接触时，上述弹性部会因受力而发生变形，使得透明摩擦层与触控驱动电极接触，而当手指离开触控感应电极后，弹性部件会为了达到形变恢复而进行振动，从而使得透明摩擦层与触控驱动电极在接触的过程中产生摩擦。通过摩擦产生的正电荷能够通过触控感应电极导出，而摩擦产生的负电荷可以通过触控驱动电极导出，以将触控过程中的机械能转换为电能。此外，上述摩擦产生的电能能够对触控驱动电极加载触控驱动信号，并检测触控感应电极通过互电容耦合出的感应电压信号，由于手指接触触控面板时，该互电容的电容值发生变化，从而改变上述感应电压信号，进而根据该感应电压信号的变化，确定触点位置。综上所述，通过该自发电式触控面板能够达到自发电触控显示的目的。
以下对上述自发电式触控面板中各个薄膜层和部件的结构进行详细的举例说明。
为了提高摩擦起电的效果，上述透明摩擦层13的材料可以包括聚氟乙烯类化合物，例如氟化乙烯丙烯共聚物(英文名：Fluorinated Ethylene Propylene，英文简称：FEP)。
此外，上述弹性部件12是在受外力的情况下，该弹性部件12上各点相对位置会发生改变，而在外力撤销后，该弹性部件12又会恢复原状。并且该弹性部件12在恢复原状的过程中会发生多次振动，且振动的幅度依次递减，最终达到静止状态。其中为了在不影响触控的前提下，提高弹性部件12在恢复原状的过程中发生振动的次数，上述弹性部件12的形变率可以为10％-15％，回弹率可以大于等于95％。需要说明的是，弹性部件12的形变率是指弹性部件12在外力作用下发生变形后的长度与该弹性部件12初始状态(不受外力时)的长度的 比值。此外，弹性部件12的回弹率是指弹性部件12在外力解除后能够恢复的长度与该弹性部件12初始状态(不受外力时)的长度的比值。
上述弹性部件12可以由弹性较好的树脂材料构成。例如可以由光刻胶材料构成。其中所述光刻胶材料可以包括50％-90％醚类或酯类的溶剂、5％-20％的丙烯酸酯类单体、5％-7％的丙烯酸酯类聚合物、0.1％-2％的分散剂、0.1％-5％的引发剂。上述材料构成的光刻胶具有较高的弹性。
具体的，可以通过掩膜曝光刻蚀工艺制作上述由光刻胶材料构成的弹性部件12。具体的，首先可以通过喷涂或旋涂的方式在触控驱动电极11上形成光刻胶薄膜层，然后通过真空干燥处理，最终得到厚度在5um～40um之间的光刻胶薄膜层。其中，当光刻胶薄膜层的厚度小于5um时，会导致形成的弹性部件12的变形量太小，从而使其在极短的时间内恢复原状。这样一来，会减小透明摩擦层13与触控驱动电极11之间相互接触和摩擦的次数，从而会导致摩擦生电过程中电荷数量的减小。此外，当光刻胶薄膜层的厚度大于40um时，虽然弹性部件12的变形量会很大，有利于增加透明摩擦层13与触控驱动电极11之间接触和摩擦次数和时间。但是会导致触控面板的厚度增加，不利于显示面板超薄化的设计趋势。
接下来，可以通过设置有预设图案的掩膜版对光刻胶薄膜层进行掩膜曝光。其中，当该光刻胶材料为正性光刻胶时，在之后的显影步骤中，可以将感光部分的光刻胶溶解掉，以形成上述弹性部件12。或者，当该光刻胶材料为负性光刻胶时，在之后的显影步骤中，可以将未感光部分的光刻胶溶解掉，以形成上述弹性部件12。其中上述掩膜版上预设图案的形状不同，得到的弹性部件12横截面的形状也不同，例如上述横截面形状可以是圆形、矩形、三角形等。该横截面平行于盖板24与相接触的表面。此外，为了提高弹性部件12的稳定性，可以将弹性部件12的纵向截面的图形如图1所示，设置为梯形。所述纵向截面与所述横向截面垂直。
在此基础上，为了增加上述光刻胶材料的韧性，使其在受压力时发生剪切屈服，吸收大量塑性形变能，在上述高弹性光刻胶材料中，还可以添加亚克力颗粒和无机填料颗粒中的至少一种。所述无机填料颗粒为粒径可以为1um-11um的碳酸钙、粒径为0.09um的超细陶瓷或粒径为3um-10um的硅球。
此外，上述触控感应电极10，如图2所示可以为多个沿第一方向X设置的 条状电极，触控驱动电极11为多个沿第二方向Y设置的条状电极。其中，第一方向X和第二方向Y交叉设置。这样一来，触控感应电极10和触控驱动电极11之间形成了互电容；在触控阶段，对触控驱动电极11加载触控驱动信号时，检测触控感应电极10通过互电容耦合出的感应电压信号，在此过程中，有人体接触该触控面板时，人体电场就会作用在互电容上，使互电容的电容值发生变化，从而改变触控感应电极10通过互电容耦合出的感应电压信号，进而根据该感应电压信号的变化，确定触点位置。当然本发明触控感应电极10和触控驱动电极11的形状不做限定，例如触控感应电极10和触控驱动电极11的形状还可以为块状，且触控感应电极10和触控驱动电极11之间无交叠区域。这样一来当位于同一行的块状的触控感应电极10可以沿第一方向X相连接，位于同一列的块状的触控驱动电极11可以沿第二方向Y相连接时，同样能够实现触控。
需要说明的是，第一、优选的上述第一方向X可以与第二方向Y垂直设置。
第二、构成触控感应电极10和触控驱动电极11的材料可以包括透明导电材料，例如氧化铟锡(英文名称：Indium Tin Oxides，英文缩写ITO)或者氧化铟锌(英文名称：Indium Zinc Oxides，英文缩写IZO)。
本发明实施例提供一种显示装置，如图3所示，包括上述任意一种自发电式触控面板01以及显示面板20，其中，自发电式触控面板01设置于显示面板20的显示侧。所述显示面板20可以为TFT-LCD(Thin Film Transistor Liquid Crystal Display，薄膜晶体管-液晶显示面板)或者有机发光二极管(Organic Light Emitting Diode，OLED)显示面板等具有显示功能的平板装置。本发明对此不做限定。
需要说明的是，当该显示面板20为LCD显示面板时，由于LCD显示面板需要设置两个偏振方向垂直的偏光片，可以将其中一个偏光片设置于LCD显示面板的阵列基板与背光模组之间。另一个可以设置于盖板24与触控感应电极10之间。此外，为了提高显示效果还可以在盖板24与触控感应电极10之间设置光学胶片，例如防反射层。
本发明实施例提供的显示装置，包括自发电式触控面板以及显示面板。其中，自发电式触控面板设置于显示面板的显示侧。这样一来，在触控的过程中，当手指与自发电式触控面板接触时，上述弹性部会因受力而发生变形，使得透明摩擦层与触控驱动电极接触，而当手指离开触控感应电极后，弹性部件会为 了达到形变恢复而进行振动，从而使得透明摩擦层与触控驱动电极在接触的过程中产生摩擦。通过摩擦产生的正电荷能够通过触控感应电极导出，而摩擦产生的负电荷可以通过触控驱动电极导出，以将触控过程中的机械能转换为电能。此外，上述摩擦产生的电能能够对触控驱动电极加载触控驱动信号，并检测触控感应电极通过互电容耦合出的感应电压信号，由于手指接触触控面板时，该互电容的电容值发生变化，从而改变上述感应电压信号，进而根据该感应电压信号的变化，确定触点位置。综上所述，通过该自发电式触控面板能够达到自发电触控显示的目的。
此外，为了使得自发电式触控面板01能够提供持续稳定的电能，所述显示装置还可以包括压力采集器30、驱动器31以及振动器32。
在此情况下，压力采集器30与自发电式触控面板01和驱动器31相连接，用于对自发电式触控面板01上的触控压力进行采集，并将采集信号发送至驱动器31。
所述驱动器31还连接振动器32，用于根据采集信号驱动振动器32进行振动。例如当压力采集器30采集到自发电式触控面板01上的触控压力较大时，其向驱动器31发出的采集信号较强，这样一来驱动器31可以控制振动器32以较高频率进行振动。当压力采集器30采集到自发电式触控面板01上的触控压力较小时，其向驱动器31发出的采集信号较弱，这样一来驱动器31可以控制振动器32以较低频率进行振动。
此外，所述振动器32还连接自发电式触控面板01，这样一来在驱动器31的驱动下，振动器32可以进行持续的振动，从而带动自发电式触控面板01中的弹性部件12进行持续的振动，从而使得透明摩擦层13与触控驱动电极10相互接触并持续产生摩擦，从而在摩擦的过程中产生持续稳定的电荷，以提供给该自发电式触控面板用于实现触控显示。
进一步的，如图4所示，自发电式触控面板01的四周通过胶合层21与显示面板20相粘合，该胶合层21的厚度可以为0.4mm-0.6mm。由于胶合层21只将自发电式触控面板01的四周与显示面板20的四周进行粘合，因此可以在自发电式触控面板01与显示面板20之间形成厚度为0.4mm-0.6mm的空气间隙。通过该空气间隙能够减小显示面板20对自发电式触控面板01的辐射噪声和寄生电容。
此外，为了更好地阻隔显示面板20产生的干扰杂讯对自发电式触控面板01的不良影响。如图4所示，在自发电式触控面板01与显示面板20之间可以设置相互接触的绝缘层22和屏蔽层23。该绝缘层22还与自发电式触控面板01相接触，屏蔽层23还与胶合层21相接触。
本发明实施例提供一种显示装置的控制方法。所述显示装置如图3所示包括自发电式触控面板01、显示面板20、压力采集器30、驱动器31以及振动器32。如图5所示，所述方法可以包括：
S101、自发电式触控面板01接收触控信号。
S102、压力采集器30根据触控信号对自发电式触控面板01上的触控压力进行采集，并将采集信号发送至驱动器31。
S103、驱动器31根据采集信号驱动振动器32进行振动。
S104、自发电式触控面板01中的弹性部件12在振动器32的带动下发生变形，使得自发电式触控面板01中的透明摩擦层13与触控驱动电极10相互摩擦产生电荷。
本发明实施例提供的显示装置的控制方法包括，首先自发电式触控面板接收触控信号；接下来压力采集器根据触控信号对自发电式触控面板上的触控压力进行采集，并将采集信号发送至驱动器；然后，驱动器根据采集信号驱动振动器进行振动；接下来，自发电式触控面板中的弹性部件在振动器的带动下发生变形，使得自发电式触控面板中的透明摩擦层与触控驱动电极相互摩擦产生电荷，以将触控过程中的机械能转换为电能。这样一来，上述摩擦产生的电能能够对触控驱动电极加载触控驱动信号，并检测触控感应电极通过互电容耦合出的感应电压信号，当手指接触该触控面板时，该互电容的电容值发生变化，从而改变触控感应电极通过互电容耦合出的感应电压信号，进而根据该感应电压信号的变化，确定触点位置。综上所述，通过该显示装置的控制方法能够达到自发电触控显示的目的。
以上所述，仅为本发明的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
