具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结 合附图对本公开提供的一种显示面板、显示装置和虚拟现实设备进行详细描述。
本公开中的显示面板特别适用于VR设备或AR设备中的显示面板。在本公开中，术语“实际分辨率”是指显示面板的物理分辨率，术语“显示分辨率”是指显示面板在进行画面显示时采用的分辨率，其中显示分辨率小于或等于实际分辨率。
图1为本发明实施例提供的一种显示面板的结构示意图。如图1所示，显示面板1包括中间显示区域101和环绕中间显示区域101的外围显示区域102。该显示面板1在进行画面显示时，驱动显示面板1使得中间显示区域101的显示分辨率大于外围显示区域102的显示分辨率。
在用户使用VR/AR设备时，用户对显示面板1中间显示区域101的注意力最集中，而对于外围显示区域102的注意力相对分散。考虑到上述现象，本公开的技术方案打破现有技术中的显示面板上各位置的显示分辨率均相等的常规设定，对显示面板1的显示区域进行划分，且使得中间显示区域101的显示分辨率大于环绕中间显示区域101的外围显示区域102的显示分辨率，以适应人眼观看习惯，从而能有效提升用户的体验质量，同时在保证低功耗的条件下保证了显示效果。
需要说明的是，本发明实施例中的显示面板1既可以为平面显示面板，也可以为曲面显示面板。可选地，显示面板1为曲面显示面板。显示面板可由柔性材料制成，例如可以采用PET(Polyethylene terephthalate，聚对苯二甲酸乙二醇酯)等柔性材料。可选地，曲面显示面板的弯曲弧度采用人眼最大视野弧度，可以保证完美的临场感。
可选地，显示面板的外围显示区域的显示分辨率随着远离中间显示区域而减小
图2为本发明实施例提供的一种显示面板的结构示意图。如图2所示，在本实施例中，环绕中间显示区域101的外围显示区域102包括多个外围显示子区域1021、1022和1023，中间显示区域101的显示分辨率大于各外围显示子区域1021、1022和1023的显示分辨率。
可选地，对于所述外围显示子区域中的任意两个相邻的外围显示子区域，距离中间显示区域较远的外围显示子区域围绕距离所述中间显示区域较近的外围显示子区域。可选地，对于任一外围显示子区域1021、1022和1023，其显示分辨率大于位于其远离中间显示区域101一侧的其他外围显示子区域的显示分辨率。
考虑到在从显示面板1的中心点指向显示面板1的边缘的方向上，用户的注意力会逐渐下降的特性，本公开通过使得各外围显示子区域1021、1022和1023的显示分辨率随着远离中间显示区域101而逐渐减小，可更佳的匹配人眼观看习惯，从而能进一步地提升用户的体验质量。
作为一种可选方案，各外围显示子区域1021、1022和1023均为环形。如图2所示，外围显示子区域的数量为三个，并且所述三个外围显示子区域从靠近中间显示区域101的一侧到远离中间显示区域101的一侧包括：第一外围显示子区域1021、第二外围显示子区域1022和第三外围显示子区域1021。
本实施例中，显示面板1对应一观看基准点，观看基准点为位于经过显示面板1的中心点的法线上且与中心点的之间的距离等于预设观看距离(人眼和显示面板1之间的距离，一般为5cm)的点；经过观看基准点并且经过显示面板在其平面图(参见图1和图2)中的左侧边缘的中点和右侧边缘的中点的水平平面为基准水平平面，经过观看基准点并且经过显示面板在其平面图(参见图1和图2)中的上侧边缘的中点和下侧边缘的中点的竖直平面为基准竖直平面。基准水平平面上经过观看基准点且与经过显示面板的中心点的法线垂直的直线定义为水平转轴线，基准竖直平面上经过观看基准点且与经过显示面板的中心点的法线垂直的直线定义为竖直转轴线。
图3为示出人眼在水平方向上的可视范围的示意图，图4为人眼示出人眼在竖直方向上的可视范围的示意图。根据上述定义，图3所示平面即为基准水平面，图4所示平面即为基准竖直平面。如图3和图4所示，当人体处于自然状态时，人眼视线与基准竖直平面平行，同时，人眼视线与基准水平平面呈15°且视线向下延伸(参见图4)。 在该情况下，人眼在水平方向上的最大可视视角为190°，即人眼视线左侧95°的范围和人眼视线右侧95°的范围，如图3所示；人眼在竖直方向上的最大可视视角为150°，即人眼视线下侧60°范围和人眼视线上侧90°范围，如图4所示。
为适应人眼在水平方向上以及竖直方向上的最大可视视角，在本发明实施例中，以基准竖直平面为分界，显示面板1在基准竖直平面的一侧(例如，图3中基准竖直平面的上侧)的可视视角为95°，在基准竖直平面另一侧(例如，图3中基准竖直平面的下侧)的可视视角为95°；以基准水平平面为分界，显示面板1在基准水平平面的一侧(例如，图4中基准水平平面的上侧)的可视视角为75°，显示面板1在基准水平平面的另一侧(例如，图4中基准水平平面的下侧)的可视视角为75°。
可选地，显示面板1在其平面图中的上(下)侧边缘的长度M和左(右)侧边缘的长度N的比值为8∶3，即位于基准竖直平面的一侧的显示画面的长宽比为4∶3，位于基准竖直平面的另一侧的显示画面的长宽比为4∶3，长宽比为4∶3的显示画面具有最小失真的画面。
显示面板可以包括如下四个显示区域：
1)中间显示区域101：
基准水平平面以水平转轴线为转轴进行顺时针旋转第一角度过程中，显示面板1上被扫过的区域为第一区域。
基准竖直平面以竖直转轴线为转轴进行顺时针旋转第二角度过程中，以及基准竖直平面以竖直转轴线为转轴进行逆时针旋转第二角度过程中，显示面板1上被扫过的区域为第二区域。
中间显示区域101为第一区域和第二区域的交叠区域。
可选地，第一角度为30°，第二角度为15°。
2)第一外围显示子区域1021：
基准水平平面以水平转轴线为转轴进行顺时针旋转第三角度过程中，以及基准水平平面以水平转轴线为转轴进行逆时针旋转第四角度过程中，显示面板1上被扫过的区域为第三区域；其中，第三角度 大于第一角度。
基准竖直平面以竖直转轴线为转轴进行顺时针旋转第五角度过程中，以及基准竖直平面以竖直转轴线为转轴进行逆时针旋转第五角度过程中，显示面板1上被扫过的区域为第四区域；其中，第五角度大于第二角度。
第一外围显示子区域1021为第三区域和第四区域的交叠区域中位于中间显示区域101之外的区域。
可选地，第三角度为35°，第四角度为25°，第五角度为35°。
3)第二外围显示子区域1022：
基准水平平面以水平转轴线为转轴进行顺时针旋转第六角度过程中，以及基准水平平面以水平转轴线为转轴进行逆时针旋转第七角度过程中，显示面板1上被扫过的区域为第五区域；其中，第六角度大于第三角度，第七角度大于第四角度。
基准竖直平面以竖直转轴线为转轴进行顺时针旋转第八角度过程中，以及基准竖直平面以竖直转轴线为转轴进行逆时针旋转第八角度过程中，显示面板1上被扫过的区域为第六区域；其中，第八角度大于第五角度。
第二外围显示子区域1022为第五区域和第六区域的交叠区域中位于中间显示区域101和第一外围显示子区域1021以外的区域。
可选地，第六角度为60°，第七角度为55°，第八角度为90°。
4)第三外围显示子区域1023：
基准水平平面以水平转轴线为转轴进行顺时针旋转第九角度过程中，以及基准水平平面以水平转轴线为转轴进行逆时针旋转第十角度过程中，显示面板1上被扫过的区域为第七区域；其中，第九角度大于第六角度，第十角度大于第七角度。
基准竖直平面以竖直转轴线为转轴进行顺时针旋转第十一角度过程中，以及基准竖直平面以竖直转轴线为转轴进行逆时针旋转第十一角度过程中，显示面板1上被扫过的区域为第八区域；其中，第十一角度大于第八角度。
第三外围显示子区域1023为第七区域和第八区域的交叠区域中 位于中间显示区域101、第一外围显示子区域1021和第二外围显示子区域1022以外的区域。
可选地，第九角度为75°，第十角度为75°，第十一角度为95。
在本实施例中，为便于显示面板1的制备，各外围显示子区域和中间显示区域101的实际分辨率均相等。进一步地，为保证用户在预设观看距离(一般为5cm)观看显示面板1时，显示面板1的显示质量达到视网膜显示(Retina Display)的水平，可使得各外围显示子区域和中间显示区域101的实际分辨率均大于2000ppi。与此同时，考虑到实际分辨率过大时，会导致成本升高、工艺难度提升的问题，本发明实施例中可使得各外围显示子区域和中间显示区域101的实际分辨率在2000ppi～2100ppi之间。
作为本实施例中的一种可选显示方案，假定中间显示区域101的显示分辨率为a，a取值在2000ppi～2100ppi之间。
可选地，第一外围显示子区域1021的显示分辨率可在a*Cos2(35°)～a之间取值(可以取值为a*Cos2(35°)，不可取值为a)。
可选地，第二外围显示子区域1022的显示分辨率可在0～a*Cos2(35°)之间取值(不可取值为0和a*Cos2(35°))。
可选地，第三外围显示子区域1023的显示分辨率小于第二外围分辨率且趋近于0。
作为一种具体方案，各外围显示子区域和中间显示区域101的实际分辨率为2100ppi，中间显示区域101的显示分辨率为2000ppi。
由上述内容可见，本发明实施例提供的显示面板1进行画面显示时，至少各外围显示子区域中存在未进行显示的像素，这些未显示的像素可作为备选像素以供用户进行操作。此外，由于显示面板上部分像素未进行显示，因而可有效降低显示面板的整体功耗。
需要说明的是，上述在实现各显示区域的显示分辨率不等时，显示面板上各显示区域的实际分辨率相等的情况，为本公开中的优选方案，其不会对本公开技术方案产生限制。本领域技术人员应该知晓的是，本发明实施例中的显示面板上各显示区域的实际分辨率可以不 完全相等，仅需保证各显示区域的实际分辨率大于等于显示分辨率即可。在本公开的一个或多个实施例中，显示面板的中间显示区域的实际分辨率大于外围显示区域的实际分辨率。
为适应显示的高实际分辨率需求，本实施例中选用微LED作为显示面板1上构成像素的发光元件，微LED的尺寸目前最小为1um，可以适应显示的高实际分辨率需求。在本公开的一个或多个实施例中，显示面板的中间显示区域和外围显示区域分别具有不同像素密度的微LED。
需要说明的是，上述外围显示子区域的形状为环形的情况，仅起到示例性作用，本发明实施例中的外围显示子区域也可以为方形等其它任意形状，另外环形可以为连续的也可以包括独立的几个部分。此外，本发明实施例中的“环绕”并不限于外围显示区域(或外围显示子区域)从上、下、左、右四个方向对中间显示区域进行包围以形成一个封闭图形的情况，而是可以包括外围显示区域(或外围显示子区域)位于中间显示区域的至少一侧。
图5为本发明实施例中提供的又一种显示面板的结构示意图，如图5所示，外围显示子区域1021a/1021b/1022a/1022b/1023a/1023b的形状为长条形，外围显示子区域的数量为6个，6个外围显示子区域对称设置于中间显示区域的两侧。其中，外围显示子区域1021a/1022a/1023a环绕于中间显示区域101的左侧，外围显示子区域1021b/1022b/1023b环绕于中间显示区域101的右侧。外围显示子区域1021a/1022a/1023a与外围显示子区域1021b/1022b/1023b关于显示面板的中线对称。
可选地，外围显示子区域1021a/1021b的显示分辨率大于外围显示子区域1022a/1022b的显示分辨率，外围显示子区域1022a/1022b的显示分辨率大于外围显示子区域1023a/1023b的显示分辨率。在图5所示情况中，可以根据预先实验来设定中间显示区域101以及各外围显示子区域1021a/1021b/1022a/1022b/1023a/1023b的显示分辨率。
当然，本发明实施例中还可以采用其他的区域划分方式，此处 不再一一举例。
图6至图9为本发明实施例中显示面板内的驱动模块的四种不同结构示意图。如图6至图9所示，本发明实施例中的显示面板的左、右两侧均具备独立的驱动模块，用于分别驱动显示面板显示左侧画面和右侧画面。驱动模块包括：栅驱动器2和源驱动器3，栅驱动器2用于向显示面板中的栅线(未示出)输出扫描信号，源驱动器3用于向显示面板中的数据线(未示出)输出数据信号。
可选地，栅驱动器可采用GOA(Gate Driver On Array)驱动电路(图6和图8中所示)来实现，或者采用若干个栅极驱动芯片IC(图7和图9中所示)来实现。
在一个或多个实施例中，栅极驱动器可包括两个独立的驱动部分，分别用于驱动显示面板的左侧部分和右侧部分进行显示。
可选地，源驱动器包括若干个源驱动子电路DR，全部源驱动子电路DR位于显示面板的一侧(图6和图7所示)或者相对两侧(图8和图9所示)。当全部源驱动子电路DR位于显示面板的一侧时，数据线的一端与对应的源驱动子电路连接，数据线被单向驱动；当全部源驱动子电路DR位于显示面板的相对两侧时，数据线的两端均与对应的源驱动子电路DR连接，数据线被双向驱动。双向驱动方式可有效提高驱动效率。
需要说明的是，对于栅驱动器2和源驱动器3进行配合，以实现画面显示的具体过程，此处不进行详细描述。

图11为利用本发明实施例中的显示装置对显示分辨率进行调整的示意图。如图11所示，当用户需要提升显示面板某区域的显示分辨率时，用户可通过诸如鼠标等输入装置选定待调整区域，区域选定单元4识别出用户选定的待调整区域，分辨率调整单元5对该待调整区域进行清晰化处理，并驱动该待调整区域内更多的像素进行画面显示。需要说明的是，本发明实施例中所使用的清晰化处理算法可为现有的任意一种低分辨率转化为高分辨率的图像处理算法。当然，本发明实施例中也可根据用户需求对待调整区域的显示分辨率进行调低处理，具体过程此处不进行详细描述。
需要说明的是，用户在观看画面时，可通过输入装置选中画面中不清晰的部分并调整该部分的显示分辨率，直到显示面板1上各位置的显示质量均满足用户的需求。
可选地，该显示装置还包括：存储单元(存储器)8，存储单元8用于相关联地存储待调整区域的位置信息和待调整区域被调整后的显示分辨率信息。通过存储单元存储用户的历史设置，在用户下次使用时，可方便用户直接进行调用。
可选地，显示装置还包括第二处理器(如芯片)，该第二处理器起到像素选定单元6和备选像素确定单元7的作用。像素选定单元6用于选择显示面板1上的异常像素，备选像素确定单元7用于确定异常像素周边的未进行显示的备选像素，并驱动未进行显示的备选像素进行显示。
图12为利用本发明实施例中的显示装置对异常像素进行补偿的示意图。如图12所示，当用户发现某个像素显示异常时，则可通过输入装置(如鼠标)选定该异常像素，像素选定单元6识别出用户选定的异常像素，备选像素确认单元7查找并确定距离该异常像素最近的备选像素，并驱动所确定的备选像素进行显示，同时关闭该异常像素。
本发明实施例还提供了一种虚拟现实设备，该虚拟现实设备包括显示装置，该显示装置采用上述实施例中提供的显示装置，具体描述可参见上述实施例中的内容，此处不再赘述。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
