详述
为使本公开的目的、技术方案和优点更加清楚明白，下文中将结合附图对本公开的实施例进行详细说明。注意，实施方式可以以多个不同形式来实施。所属技术领域的普通技术人员可以很容易地理解一个事实，就是方式和内容可以在不脱离本公开的宗旨及其范围的条件下被变换为各种各样的形式。因此，本公开不应该被解释为仅限定在下面的实施方式所记载的内容中。在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。为了保持本公开实施例的以下说明清楚且简明，本公开省略了部分已知功能和已知部件的详细说明。本公开实施例附图只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计
本公开中的附图比例可以作为实际工艺中的参考，但不限于此。例如：沟道的宽长比、各个膜层的厚度和间距、各个信号线的宽度和间距，可以根据实际需要进行调整。显示基板中像素单元的个数和每个像素单元中子像素的个数也不是限定为图中所示的数量，本公开中所描述的附图仅是结构示意图，本公开的一个方式不局限于附图所示的形状或数值等。
本说明书中的“第一”、“第二”、“第三”等序数词是为了避免构成要素的混同而设置，而不是为了在数量方面上进行限定的。
在本说明书中，为了方便起见，使用“中部”、“上”、“下”、“前”、“后”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示方位或位置关系的词句以参照附图说明构成要素的位置关系，仅是为了便于描述本说明书和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。构成要素的位置关系根据描述各构成要素的方向适当地改变。因此，不局限于在说明书中说明的词句，根据情况可以适当地更换。
在本说明书中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解。例如，可以是固定连接，或可拆卸连接，或一体地连接；可以是机械连接，或电连接；可以是直接相连，或通过中间件间接相连，或两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
在本说明书中，晶体管是指至少包括栅电极、漏电极以及源电极这三个端子的元件。晶体管在漏电极(漏电极端子、漏区域或漏电极)与源电极(源电极端子、源区域或源电极)之间具有沟道区域，并且电流能够流过漏电极、沟道区域以及源电极。注意，在本说明书中，沟道区域是指电流主要流过的区域。
在本说明书中，第一极可以为漏电极、第二极可以为源电极，或者第一极可以为源电极、第二极可以为漏电极。在使用极性相反的晶体管的情况或电路工作中的电流方向变化的情况等下，“源电极”及“漏电极”的功能有时互相调换。因此，在本说明书中，“源电极”和“漏电极”可以互相调换。
在本说明书中，“电连接”包括构成要素通过具有某种电作用的元件连接在一起的情况。“具有某种电作用的元件”只要可以进行连接的构成要素间的电信号的授受，就对其没有特别的限制。“具有某种电作用的元件”的例子不仅包括电极和布线，而且还包括晶体管等开关元件、电阻器、电感器、电容器、其它具有各种功能的元件等。
在本说明书中，“平行”是指两条直线形成的角度为-10°以上且10°以下的状态，因此，也包括该角度为-5°以上且5°以下的状态。另外，“垂直”是指两条直线形成的角度为80°以上且100°以下的状态，因此，也包括85°以上且 95°以下的角度的状态。
在本说明书中，“膜”和“层”可以相互调换。例如，有时可以将“导电层”换成为“导电膜”。与此同样，有时可以将“绝缘膜”换成为“绝缘层”。
在本说明书中，所采用的“同层设置”是指两种(或两种以上)结构通过同一次图案化工艺得以图案化而形成的结构，它们的材料可以相同或不同。例如，形成同层设置的多种结构的前驱体的材料是相同的，最终形成的材料可以相同或不同。
本说明书中三角形、矩形、梯形、五边形或六边形等并非严格意义上的，可以是近似三角形、矩形、梯形、五边形或六边形等，可以存在公差导致的一些小变形，可以存在导角、弧边以及变形等。
本公开中的“约”，是指不严格限定界限，允许工艺和测量误差范围内的数值。
全面屏手机包括：透光显示区和正常显示区，目前全面屏手机的透光显示区没有触控功能，随着摄像头区域所占的面积的增大，没有触控功能的透光显示区影响全面屏手机的使用，降低了全面屏手机的可靠性。
