附图说明
下面结合附图，通过对本发明的具体实施方式详细描述，将使本发明的技术方案及其他有益效果显而易见。
附图中，
图1为人眼聚焦时对画质的要求示意图；
图2为现有显示装置基本架构示意图；
图3为本发明低功耗智能显示装置一较佳实施例的基本架构示意图。
具体实施方式
参见图3，其为本发明低功耗智能显示装置一较佳实施例的基本架构示意图。本发明的低功耗智能显示装置主要包括：触控显示模块31，驱动模块32以及系统模块33，该触控显示模块31与驱动模块32连接，该驱动模块32与系统模块33连接，该驱动模块32包括显示驱动模块321和触控驱动模块322；该系统模块33根据待显示的显示图像产生显示数据，该显示驱动模块321根据系统模块33产生的显示数据驱动触控显示模块31进行显示，该触控驱动模块322驱动触控显示模块31检测触控位置信息以及反馈触控位置信息给系统模块33；当该触控驱动模块322检测到有手指触摸发生时，将触摸发生的坐标反馈至该系统模块33，该系统模块33根据手指触摸发生的坐标位置确定人眼的聚焦区域及非聚焦区域，该系统模块33根据待显示的显示图像产生显示数据时对应于该非聚焦区域降低单位时间内显示数据量；当该触控驱动模块322检测到无手指触摸发生时，该系统模块33根据待显示的显示图像正常产生显示数据。
下面结合大屏幕手机来具体说明本发明，系统模块33可以为手机系统端，触控驱动模块322可以为触控芯片，显示驱动模块321可以为显示芯片，触控显示模块31可以为手机触控显示屏，手机系统端产生对应于1440*2560分辨率RGB模式的显示图像的显示数据，显示芯片根据显示数据驱动手机触控屏显示1440*2560分辨率RGB模式的显示图像，触控IC检测到手机触控屏上有手指触摸发生时，将触摸发生的坐标反馈至手机系统端。在此较佳实施例中，聚焦区和非聚焦区的划分方式可以预先规定，图3中以较为简易方式进行划分，以手指所在区域为聚焦区，沿虚线将触控显示模块31左右划分为聚焦区和非聚焦区。也可以采用上下划分或其他适合的划分方式。
当触控IC检测到无手指触摸发生时，手机系统端则进行正常的数据更新。对应于待显示的1440*2560分辨率RGB模式的显示图像，手机系统端按照正常的方式产生显示数据，并提供给显示芯片来驱动手机触控显示屏进行高画质显示1440*2560分辨率RGB模式的显示图像。
当触控IC检测到有手指触摸发生时，将触摸发生的坐标反馈至手机系统端，手机系统端根据坐标位置判断人眼的聚焦区域，当系统端获得触摸发生的区域时则判断此区域范围即为人眼所聚焦的部分(基于手指触摸时，人眼会同步聚焦于触摸的位置的特点)，此部分对显示数据要求的清晰度较高，数据需保持正常的更新；而其它不被人眼聚焦的部分，对数据要求的清晰度较低，数据则不需要更新或保持较低的频率进行更新。

停止对应于该非聚焦区域的显示数据的更新；
降低对应于该非聚焦区域的显示图像的画质，例如降低亮度；
降低对应于该非聚焦区域的显示数据的更新频率，也就是非聚焦区域的显示数据为低频数据；
降低对应于该非聚焦区域的显示数据的灰阶，也就是非聚焦区域的显示数据为低Bit数据。
本发明适用于LCD显示行业，尤其涉及一种根据触控位置降低部分画面的画质或频率或Bit数的新型低功耗智能显示装置。
本发明还提供了相应的低功耗智能显示装置的显示方法，包括：
步骤10、当触控驱动模块检测到有手指触摸发生时，将触摸发生的坐标反馈至系统模块，该系统模块根据手指触摸发生的坐标位置确定人眼的聚焦区域及非聚焦区域；
步骤20、该系统模块根据待显示的显示图像产生显示数据时对应于该非聚焦区域降低单位时间内显示数据量；
步骤30、当该触控驱动模块检测到无手指触摸发生时，该系统模块根据待显示的显示图像正常产生显示数据。
下面结合大屏幕手机来说明该方法，对于步骤10，当触控IC检测到有手指触摸发生时，并将触摸发生的坐标反馈至手机系统端，手机系统端根据手指触摸发生的坐标位置，判断人眼的聚焦区域(基于手指触摸时，人眼会同步聚焦于触摸的位置的特点)，并进一步确定非聚焦的区域及要进行低画质或低频数据或低Bit数据更新的部分。
对于步骤20，因人眼所聚焦的部分，此部分对数据要求的清晰度较高，数据需保持正常的更新；而其它不被人眼聚焦的部分，对数据要求的清晰度较低，数据则不需要更新或保持较低的低画质或低频数据或低Bit数据进行更新，以达到节省功耗却不影响视觉效果的目的。
对于步骤30，当触控IC检测到手指停止触摸时，手机系统端则恢复正常的数据更新。
综上，本发明的低功耗智能显示装置及其显示方法能够在不影响显示效果的前提下降低大显示屏显示装置的功耗。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形 都应属于本发明后附的权利要求的保护范围。
