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显示基板，包括：衬底基板10(在图2或图4示出)，以及如图1所示，位于上述衬底基板10上的用于测试环境压力的压力传感结构20，该压力传感结构可以包括相对设置的第一压敏电极201和第二压敏电极202，以及位于第一压敏电极201和第二压敏电极202之间的多个间隔设置的绝缘支柱203。并且，第一压敏电 极201与衬底基板10相接触。
需要说明的是，上述衬底基板10为透明基板，具体地可以由玻璃或者树脂构成，用于在该基板上制作各种薄膜层。例如，当上述显示基板应用于液晶显示装置时，该显示基板可以为彩膜基板，从而能够在上述衬底基板10上制备黑矩阵和彩色膜层的图案；或者上述显示基板可以为阵列基板，从而在上述衬底基板10上一次制备薄膜晶体管阵列。此外，当上述显示基板应用于OLED(Organic Light Emitting Diode，有机发光二极管)显示装置时，上述衬底基板10可以为封装盖板，从而对OLED阵列基板进行封装。又或者，当显示基板用于制作柔性显示面板时，上述衬底基板10还可以由柔性透明树脂材料构成。
为了容易对其进行区分，将与衬底基板10相接触的压敏电极称为第一压敏电极201，与第一压敏电极201相对设置的另一个压敏电极称为第二压敏电极202。第一压敏电极201并不是必须如图1所示相对于第二压敏电极202，总是更靠近显示装置的出光显示侧。当压力传感结构20设置于不同类型的显示基板时，第一压敏电极201与第二压敏电极202之间的相对位置可以有所不同。例如，如图2所示，当该显示基板为彩膜基板时，由于彩膜基板的衬底基板10位于显示装置的出光显示侧，因此与衬底基板10相接触的第一压敏电极201，相对于第二压敏电极202而言，更靠近显示装置的出光显示侧。又例如，如图7所示，当显示基板为阵列基板时，由于阵列基板的衬底基板10位于显示装置远离出光显示侧的一侧，因此与衬底基板10相接触的第一压敏电极201相对于第二压敏电极202而言，更远离显示装置的出光显示侧。
上述构成第一压敏电极201或第二压敏电极202的材料可以包括一些透明导电材料，例如石墨烯、碳纳米管、纳米银以及氧化铟锡、氧化铟锌中的至少一种。由于石墨烯或碳纳米管的压敏性能较高，因此优选地可以采用石墨烯或碳纳米管中的至少一种。此外，构成上述绝缘支柱203的材料可以选用绝缘的树脂材料，例如在显示领域常用的光刻胶材料，或者还可以根据显示基板的不同，在绝缘支柱203的制备过程中采用制备该显示基板时采用的树脂材料。
第一压敏电极201和绝缘支柱203的图案可以通过构图工艺在衬底基板10上依次形成。然而由于第一压敏电极201和第二压敏电极202 的支架需要通过绝缘支柱203形成一定的间距。因此在制备压力传感结构20的过程中，需要将已经制备好的第二压敏电极202的薄片(film)结构贴附于绝缘支柱203，从而使得第一压敏电极201和第二压敏电极202之间能够形成电容。
由于环境压力作用于显示基板的第一压敏电极201时，第一压敏电极201的整个表面都会受到上述环境压力的作用。而当用户的手指触摸显示基板时，用户施加的压力只作用于第一压敏电极201的局部表面。因此可以针对第一压敏电极201的受力面积的不同，设置相应的算法，以使得显示基板能够区分出环境压力和用户触控时产生的压力，从而避免用户触控时产生的压力对环境压力测试结果的影响。
本发明实施例所述的构图工艺可包括光刻工艺，或，包括光刻工艺以及刻蚀步骤，同时还可以包括打印、喷墨等其他用于形成预定图形的工艺。光刻工艺是指包括成膜、曝光、显影等工艺过程的利用光刻胶、掩模板、曝光机等形成图形的工艺。可根据本发明中所形成的结构选择相应的构图工艺。
本发明实施例中的一次构图工艺是以通过一次掩膜曝光工艺形成不同的曝光区域，然后对不同的曝光区域进行多次刻蚀、灰化等去除工艺最终得到预期图案为例进行说明。
本发明实施例提供的显示基板包括衬底基板，以及用于测试环境压力的压力传感结构，压力传感结构包括相对设置的第一压敏电极和第二压敏电极，以及位于第一压敏电极和第二压敏电极之间的多个间隔设置的绝缘支柱；第一压敏电极与衬底基板相接触。
这样一来，第一压敏电极和第二压敏电极之间会形成一个电容。当气压或水压作用于衬底基板，会使得上述衬底基板发生微量变形。在此情况下，与衬底基板相接触的第一压敏电极会在上述微量变形的作用下发生变形，从而使得第一压敏电极与第二压敏电极之间的间距发生变化，导致第一压敏电极和第二压敏电极之间的电容值发生变化。通过对上述电容值进行采集和换算即可以得出相应的压力数值。
此外，由于上述压力传感结构集成于显示基板中，而显示基板在一些便携式显示装置领域的应用非常广泛，因此，当将该显示基板应用于上述显示装置时，可以通过显示装置将通过压力传感结构检测得到的压力数值进行显示，或者将上述压力数值与已设定的压力阈值进 行比较，当上述压力数值超过上述阈值时显示提示信息。从而该技术方案能够在便于用户携带的基础上，对外界的气压或水压进行检测。
以下通过具体的实施例对设置有上述压力传感结构20的显示基板进行详细的说明。
实施例一
本实施例以上述显示基板为彩膜基板01为例进行说明。
在此情况下，如图2所示，显示基板包括位于衬底基板10上的黑矩阵11，而压力传感结构20位于黑矩阵11与衬底基板10之间。其中，上述彩膜基板01还包括黑矩阵11和彩色膜层12。该彩色膜层12由第一颜色图案、第二颜色图案以及第三颜色图案构成。上述第一颜色、第二颜色和第三颜色可以分别为构成三原色的红色、绿色和蓝色，或者还可以为青色、品红、黄色。本发明对此不做限定。但以下实施例均是以第一颜色为红色(R)，第二颜色为绿色(G)，第三颜色为蓝色(B)为例进行说明。
此外，当上述显示基板(彩膜基板01)应用于TN(Twist Nematic，扭曲向列)型显示装置时，如图2所示，该显示基板还包括彩色膜层12以及位于该彩色膜层12远离衬底基板10一侧的公共电极层13。在此情况下，显示基板如图3所示，可以包括显示区域101(即AA区，英文：Ative Area，中文：有效显示区域)以及位于显示区域101周边的非显示区域102。由于如图2所示，在显示基板的非显示区域102处，公共电极层13和第二压敏电极202之间无需设置彩色膜层12和黑矩阵，因此为了防止第二压敏电极202对公共电极层13造成信号干扰，可以在第二压敏电极202与公共电极层13之间设置绝缘层14。
需要说明的是，上述TN型显示装置是采用垂直电场原理的液晶显示器，通过被相对布置在彩膜基板01上的公共电极13和在阵列基板02上的像素电极(图中未示出)之间形成垂直电场来驱动扭转向列模式的液晶03。垂直电场液晶显示器具有大孔径比的优点。
此外，为了提高显示基板的透过率，还可以将压力传感结构20设置于非显示区域102。由于非显示区域102设置于显示区域101的四周。因此当压力传感结构20设置于非显示区域102时，可以在显示区域101的至少一侧，例如左侧或右侧设置上述压力传感结构20。
以下实施例将以显示基板为彩膜基板01并且压力传感结构20被 设置于非显示区域102为例对显示基板的结构进行详细的说明。其中，当显示基板为彩膜基板01时，该彩膜基板01包括黑矩阵11、彩色膜层12以及公共电极层13。该彩色膜层12由第一颜色图案(R)、第二颜色图案(G)以及第三颜色图案(B)构成。
实施例二
本实施例中，上述显示基板为彩膜基板01，且压力传感结构20设置于非显示区域102。
具体地，如图4所示，公共电极层13与第二压敏电极202之间包括构成第一颜色图案(R)、第二颜色图案(G)和第三颜色图案(B)中的至少一个的材料。此外，绝缘支柱203可以与黑矩阵11具有相同材料并且位于同一层或利用同一构图工艺形成。
这样一来，在上述彩膜基板01的制备过程中，就可以完成压力传感结构20的制备。具体地，首先，在衬底基板10的表面对应非显示区域102的位置通过构图工艺形成第一压敏电极201，然后在衬底基板10和第一压敏电极201上均涂覆一层薄膜层，该薄膜层的材料与构成黑矩阵11的材料相同；然后通过一次掩膜曝光、刻蚀工艺在衬底基板10的表面形成黑矩阵11图案的同时，在第一压敏电极201的表面形成绝缘支柱203的图案，从而使得绝缘支柱203与黑矩阵11同层并且具有相同材料。上述同层，可以是指绝缘支柱203与黑矩阵11位于同一水平面，或者还可以是指绝缘支柱203与黑矩阵11通过一次构图工艺同时形成。接下来，将已经制作好的薄片状的第二压敏电极202贴附于绝缘支柱203的表面，从而完成了感应电极结构20的制备。具体地，例如可以通过机械手将已经制作好的薄片状的第二压敏电极202放置于绝缘支柱203的表面，然后通过热压工艺将第二压敏电极202固定于绝缘支柱203的表面。
当然，公共电极层13与第二压敏电极202之间还可以包括由其它绝缘材料制成的具有绝缘功能的薄膜层。
在此基础上，通过构图工艺依次形成第一颜色图案(R)、第二颜色图案(G)以及第三颜色图案(B)的同时，可以在第二压敏电极202的表面形成由构成第一颜色图案(R)、第二颜色图案(G)和第三颜色图案(B)中的至少一个的材料依次叠加而成的堆叠结构。然后在形成有上述结构的表面制备一层公共电极层13。这样一来，对于将公共 电极层13制备于彩膜基板01上的TN型显示装置而言，无需单独增加制备绝缘层的步骤，以避免第二压敏电极202对公共电极层13的影响。由于构成彩色膜层12的材料为具有绝缘性能的树脂材料，因此，可以在制备彩色膜层12的过程中，形成由构成第一颜色图案(R)、第二颜色图案(G)以及第三颜色图案(B)的材料依次叠加而成的堆叠结构作为第二压敏电极202与公共电极层13之间的绝缘层。
实施例三
本实施例中，上述显示基板为彩膜基板01，且压力传感结构20设置于非显示区域102。与实施例二不同之处在于，构成绝缘支柱203的材料不同，且可以将公共电极层13与第二压敏电极202复用。
具体地，如图5所示，第二压敏电极202与公共电极层13同层并且具有相同材料。该绝缘支柱203由构成黑矩阵11、第一颜色图案(R)、第二颜色图案(G)和第三颜色图案(B)中的至少一个的材料依次叠加而成。
这样一来，在上述彩膜基板01的制备过程中，同样可以完成压力传感结构20的制备。具体地，首先，在衬底基板10的表面对应非显示区域102的位置通过构图工艺形成第一压敏电极201，然后在衬底基板10上通过构图工艺依次形成黑矩阵11、第一颜色图案(R)、第二颜色图案(G)以及第三颜色图案(B)，与此同时，可以在第一压敏电极201上依次形成由构成黑矩阵11、第一颜色图案(R)、第二颜色图案(G)和第三颜色图案(B)中的至少一个的材料堆叠而成的绝缘支柱203。接下来，在形成上述结构的基板表面，将已经制作好的薄片状的透明导电层贴附于其上，从而在对应显示区域101位置形成公共电极层13，而在对应非显示区域102的位置形成第二压敏电极202，使得第二压敏电极202与公共电极层13同层并且具有相同材料。这实现了公共电极层13与第二压敏电极202的复用，其中为了使得形成的公共电极层13能够具有与黑矩阵11和彩色膜层12的较好贴合度，可以选择柔韧性较高的碳纳米管材料构成上述透明导电层。
相比于实施例二提供的方案而言，本实施例中，当第二压敏电极202与公共电极层13相连接时，第一压敏电极202和公共电极层13可以为同一层薄膜层，因此该薄膜层既可以作为第一压敏电极202使用，也可以作为公共电极层13使用，使得公共电极层13与第二压敏电极 202能够复用。这样一来在制备过程中无需特殊工艺或步骤将公共电极层13与第二压敏电极202断开，从而可以简化制作工艺。
综上所述，上述实施例均是以显示基板为彩膜基板01为例进行的说明。当然该显示基板还可以是应用于液晶显示装置的阵列基板02，或者还可以是应用于OLED显示装置的阵列基板02。
其中，当上述显示基板为阵列基板02时，如图6a或图6b所示，阵列基板包括横纵交叉的多条栅线GATE和数据线DATA，栅线和数据线交叉界定出多个呈矩阵形式排列的像素单元Pixel。每个像素单元内设置有一个薄膜晶体管TFT，从而在阵列基板02的衬底基板10上形成了TFT阵列。并且每个TFT的漏极与像素电极210相连接。
在此情况下，可以如图6a所示，将压力传感结构20设置于上述像素单元Pixel所对应的区域。或者如图6b所示将压力传感结构20设置于像素单元Pixel所对应的区域以外的区域。基于此，可以在每个像素单元Pixel内均设置一个压力传感结构20，也可以选择性地在几个像素单元Pixel内设置一个压力传感结构20。此外，还可以如图3所示，将压力传感结构20设置于非显示区域101中。本发明对此不作限制。
由于TFT可以分为底栅型TFT和顶栅型TFT。以下实施例将根据TFT的不同类型，对将压力传感结构20集成于阵列基板20的方案进行描述。
实施例四
本实施例中，显示基板为阵列基板02，且阵列基板02上的TFT为底栅型TFT。具体地，如图7所示，栅极211与衬底基板10相接触，栅极绝缘层212覆盖栅极211。因此栅极211相对于栅极绝缘层212而言，更靠近衬底基板10，从而构成了底栅型TFT。
在此情况下，压力传感结构20中的第一压敏电极201可以与薄膜晶体管TFT的栅极211同层并且具有相同材料，绝缘支柱203可以与覆盖栅极211的栅极绝缘层212同层并且具有相同材料。这样一来，在制作TFT的过程中，就可以完成压力传感结构20的第一压敏电极201和绝缘支柱203的制备。
具体地，首先可以在衬底基板10上沉积一层栅极金属层，然后通过一次构图工艺同时形成栅极211和第一压敏电极201的图案。然后，在形成有上述图案的基板表面涂覆一层栅极绝缘层，接下来通过构图 工艺在栅极绝缘层的对应第一压敏电极201的位置形成多个间隔设置的绝缘支柱203。然后，将已经制备好的薄片(film)状第二压敏电极202贴附于绝缘支柱203的表面，从而完成了压力传感结构20的制备。接下来通过后续的构图工艺依次在栅极绝缘层212的表面形成半导体有源层213以及TFT的源漏极214等。
实施例五
本实施例中，显示基板为阵列基板02，且阵列基板02上的TFT为顶栅型TFT。具体地，如图8所示，因此栅极211相对于栅极绝缘层212而言，更远离衬底基板10，从而构成了顶栅型TFT。且为了防止光线照射到TFT的沟道区域，可以在衬底基板10的表面，对应TFT沟道区域的位置设置金属遮光层215。从而可以避免光线直接照射到TFT的沟道区域，使得TFT的漏电流减小。此外，由于金属遮光层215采用金属材料制备，因此还需要在金属遮光层215的表面覆盖一层具有绝缘性能的缓冲层216。
在此情况下，压力传感结构20中的第一压敏电极201可以与金属遮光层205同层并且具有相同材料，绝缘支柱203与缓冲层216同层并且具有相同材料。这样一来，在制作TFT的过程中，就可以完成压力传感结构20的制备。其具体的制作过程可以参考实施例四。此处不再赘述。
此外，本实施例中的TFT结构采用双栅极，即有两个栅极211。这样一来可以增加TFT区域沟道的长度，而该沟道的长度与TFT的漏电流成反比。因此上述结构可以进一步减小TFT的漏电流。
综上所述，实施例四和实施例五是以显示基板为阵列基板02为例进行的说明。此外，当显示基板包括OLED发光元件时。压力传感结构20的具体设置方式可以如以下实施例所述。
实施例六
如图9所示，该显示基板包括电极绝缘层30，该电极绝缘层30设置于第二压敏电极202远离衬底基板10的一侧，并且该第二压敏电极与电极绝缘层30相接触。而第一压敏电极201与衬底基板10相接触。此外，该电极绝缘层30远离衬底基板10的一侧设置有OLED发光元件31。其中该OLED发光元件31可以包括依次位于电极绝缘层30表面的第一电极层310、电子注入层311、电子传输层312、有机发光层 313、空穴传输层314、空穴注入层315以及第二电极层316。需要说明的是，第一电极层310可以为阴极，第二电极层316可以为阳极。由于OLED发光元件31可以分为顶发射型和底发射型。对于顶发射型OLED发光元件31而言，上述第一电极层310为透明电极，第二电极层316可以为不透明的。对于底发射型OLED发光元件31而言，第一电极层310为不透明电极，而第二电极层316可以为透明电极。
在此基础上，压力传感结构20可以位于衬底基板10与电极绝缘层30之间，并且，第一压敏电极201与衬底基板10相接触，第二压敏电极202与电极绝缘层30相接触。从而可以将压力传感结构20集成于OLED显示面板中。
本发明实施例提供一种显示装置，其包括如上所述的任意一种显示基板。该显示装置具有与前述实施例提供的显示基板相同的有益效果。由于前述实施例已经对显示基板的结构和有益效果进行了详细的描述，此处不再赘述。
需要说明的是，在本发明实施例中，显示装置具体可以包括液晶显示装置，例如该显示装置可以为液晶显示器、液晶电视、数码相框、手机或平板电脑等任何具有显示功能的产品或者部件。
本发明实施例提供一种压力检测系统，如图10所示，该压力检测系统包括如上所述的显示装置40，还包括压力信号采集器50、数据处理器60。
具体地，压力信号采集器50与显示装置40的压力传感结构20中的第一压敏电极201、第二压敏电极202以及数据处理器60相连接，用于采集第一压敏电极201和第二压敏电极202之间的电容值，并将采集结果输出至数据处理器60。
该数据处理器还连接显示装置40，用于将上述压力信号采集器50采集到的电容值转换成压力值，并输出至显示装置40，使得该显示装置40显示所述压力值。
这样一来，通过压力检测系统，可以对外界的气压或水压进行检测，并将检测结果进行显示，从而方便用户随时对外界的气压或水压有所了解，从而可以判断出外界的环境是否与身体适应能力相符。
在此基础上，上述压力检测系统还包括存储器70以及比较器80。
其中，比较器70与数据处理器60、存储器80以及显示装置40相 连接，用于接收数据处理器60输出的压力值，并将该压力值与存储器80中存储的压力阈值进行比较，当数据处理器60输出的压力值大于该压力阈值时，向显示装置40发送提示信号，使得显示装置40根据所述提示信号显示提示消息。在此情况下，无需人为对压力值与自身身体状况是否相适应进行判断，而是通过压力检测系统将检测得到的压力值与压力阈值进行判断，当检测得到的压力值超出阈值时通过显示装置显示提示消息，从而达到警示用户的作用。这样一来，避免了用户自行判断失误导致对身体健康造成不良的影响。
需要说明的是，上述压力阈值可以用户在医疗场所测试后，得到的与自身能够承受的外界压力极限值。当压力值超过上述极限值时，可能会对用户的身体造成不良的影响。或者，上述压力阈值还可以根据用户自身的需求进行设定。例如，对于一些钓鱼爱好者而言，可以根据鱼在水中分层及活跃性对上述阈值进行设定，从而根据显示装置40显示的提示信号进行钓鱼，这可以便于用户钓到鱼。当然上述仅仅是对压力阈值设定的举例说明。
本发明实施例提供一种利用上述显示装置检测压力的方法，如图11所示，该检测方法包括以下步骤：
S101、采集显示装置40中第一压敏电极201和第二压敏电极202之间的电容值。具体地，可以通过压力信号采集器50采集第一压敏电极201和第二压敏电极202之间的电容值，并将采集结果输出至数据处理器60；
S102、将该电容值转换成压力值。具体地，例如通过数据处理器60将压力信号采集器50采集到的电容值转换成压力值，并输出至显示装置40；
S103、将该压力值在显示装置40上进行显示。具体地，例如通过显示装置40将该压力值进行显示。
这样一来，通过上述压力检测方法，可以对外界的气压或水压进行检测，并将检测结果进行显示，从而方便用户随时对外界的气压或水压有所了解，从而可以判断出外界的环境是否与身体适应能力相符。
在此基础上，上述方法还包括以下步骤：
将该压力值与压力阈值进行比较，当压力值大于压力阈值时，显示装置40根据所述提示信号进行显示提示消息。具体地，例如比较器 70接收数据处理器60输出的压力值，并将所述压力值与存储器80中存储的压力阈值进行比较，当数据处理器60输出的压力值大于压力阈值时，向显示装置41发送提示信号。然后，该显示装置40根据所述提示信号进行显示。
在此情况下，无需人为对压力值与自身身体状况是否相适应进行判断，而是通过压力检测系统将检测得到的压力值与压力阈值进行判断，当检测得到的压力值超出阈值时通过显示装置显示提示信号，从而达到警示用户的作用。这样一来，既方便了用户，又避免了用户自行判断失误导致对身体健康造成不良的影响。
