 背景技术
随着电子技术的发展，如手机、平板电脑等电子设备已经成为人们日常生活和工作中不可或缺的一部分，用户对显示面板的外观设计要求越来越高。
在现有显示面板中，为提高屏占比，减小边框的尺寸，通常采用端子弯曲技术(pad bending)，其通过将显示面板的柔性PI(Polyimide，聚亚酰胺)基板的伸出端弯折到显示器的背面，从而实现非显示区域的窄边框化；但在现有显示面板在与前框配合过程中，由于弯折部的存在，因此前框必须设置一预留空间，并收纳弯折部至预留空间内，因此通常设置所述前框顶面所在的水平面高度大于所述显示部顶面所在的水平面高度（约2mm），当用户对所述显示装置进行滑屏操作时，手指会与前框边缘相互触碰，从而发生运动干涉等不良影响。

其中，在所述显示模组10出光侧的方向上，所述封装结构700的顶面所在的水平面高度大于或等于所述前框20的顶面所在的水平面高度。
需要说明的是，目前，随着电子技术的发展，如手机、平板电脑等电子设备已经成为人们日常生活和工作中不可或缺的一部分，用户对显示面板100的外观设计要求越来越高；在机发光二极管(Organic Light Emitting Diode，OLED)技术中，为提高屏占比，减小边框的尺寸，通常采用端子弯曲技术(pad bending)，如图1所示，为现有技术的一种显示装置的结构示意图，其中，所述显示装置1包括前框20和位于所述前框20内的显示模组10，所述显示模组10包括层叠设置的支撑层200、散热层400、显示面板100、功能膜层600以及封装结构700，其中，所述显示面板100包括显示区A、远离所述显示区A一侧的绑定区C及位于所述显示区A与所述绑定区C之间的弯曲区B，所述显示面板100包括位于所述显示区A内的平坦显示部110、位于所述弯曲区B内的弯曲部120以及位于所述绑定区C内且与所述平坦显示部110相对设置的绑定部130。

在本实施例中，所述显示面板100还包括沿所述平面显示部111远离所述第一弧面显示部112方向延伸的第二弧面显示部113；所述支撑层200包括沿所述第一支撑子部210远离所述第二支撑子部220方向延伸的第三支撑子部230，所述第三支撑子部230与所述第二弧面显示部113对应设置，所述第三支撑子部230的形状与所述第二弧面显示部113的形状相匹配；所述前框20还包括位于所述底框21靠近所述第二弧面显示部113一侧的第二边框23，所述第二边框23垂直于所述底框21；其中，在垂直于所述显示面板100的方向上，所述第二边框23的顶面所在的水平面高度小于或等于所述封装结构700的顶面所在的水平面高度；优选地，在本实施例中，所述第二边框23的顶面所在的水平面高度与所述封装结构700的顶面所在的水平面高度的间距为H 2。

进一步地，在本实施例中，所述底框21包括滑动连接的第一底框21A和第二底框21B，所述第一底框21A在垂直于所述显示模组10方向上的正投影与所述第二底框21B在垂直于所述显示模组10方向上的正投影至少部分重叠；所述第一边框22位于所述第一底框21A靠近所述第一弧面显示部112的一侧，所述前框20还包括位于所述第二底框21B靠近所述卷轴30一侧的第二边框23，所述第二边框23垂直于所述第二底框21B；其中，在垂直于所述显示面板100的方向上，所述第二边框23的顶面所在的水平面高度小于或等于所述封装结构700的顶面所在的水平面高度；需要说明的是，本实施例中对所述第一底框21A和所述第二底框21B滑动链接的方式不做具体限制。
可知理解的是，本实施例通过设置所述第一底框21A和所述第二底框21B滑动链接，所述第一底框21A在垂直于所述显示模组10方向上的正投影与所述第二底框21B在垂直于所述显示模组10方向上的正投影至少部分重叠从而避免所述前框20对所述显示面板100的收卷或展开造成影响；并且，通过在垂直于所述显示面板100的方向上，所述第一边框22的顶面所在的水平面高度小于或等于所述封装结构700的顶面所在的水平面高度，所述第二边框23的顶面所在的水平面高度小于或等于所述封装结构700的顶面所在的水平面高度，进而消除现有技术中滑屏时手指与所述前框20边缘相互触碰而导致运动干涉等不良现象的发生；优选地，在本实施例中，所述第一边框22的顶面所在的水平面高度与所述封装结构700的顶面所在的水平面高度地间距为H 1，所述第二边框23的顶面所在的水平面高度与所述封装结构700的顶面所在的水平面高度地间距为H 2。
进一步地，在本实施例中，所述显示装置1还包括与所述绑定部130连接的绑定元件800，及位于所述绑定部130和所述第一支撑子部210之间的支撑构件500，其中，在由所述第二边框23指向所述第一边框22的方向上，所述支撑构件500的厚度逐渐增大，从而增大了所述绑定元件800与所述第一底框21A之间的距离，能避免所述绑定元件800与所述底框21之间直接接触，减少了绑定元件800的磨损，提高了所述显示模组10的使用寿命。
