所述目标分辨率为在一定距离处能够满足人眼观看清晰度要求的分辨率。观看一定距离处的画面时人眼的清晰度要求，可以根据人机工程学的实践，从大量实验数据中确定。
进一步的，本实施例中，控制器12可以根据预设距离与所述目标分辨率的对应关系，确定所述距离所对应的所述目标分辨率，并生成具有所述目标分辨率的所述目标显示内容。具体的，控制器12可以预先配置有所述预设距离与所述目标分辨率的映射关系。当接收到所述距离时，控制器12可以将所述距离与所述预设距离对比，当判断所述距离为其中一个所述预设距离时，则可以确定与此预设距离(或所述距离)对应的目标分辨率。此种方式中，控制器12能够针对每一个所述距离，生成具有相应目标分辨率的所述目标显示内容，并控制显示屏13进行显示。由此能够实现实时、灵活的画面显示，满足用户的各种使用场合。
或者，进一步的，本实施例中，控制器12可以根据预设距离范围与所述目标分辨率的对应关系，确定所述距离所对应的所述目标分辨率，并生成具有所述目标分辨率的所述目标显示内容。具体的，控制器12可以预先配置有所述预设距离范围与所述目标分辨率的映射关系。当接收到所述距离时，控制器12可以判断所述距离位于哪个所述预设距离范围内。当判断所述距离落入其 中一个所述预设距离范围时，则可以确定与此预设距离范围(或所述距离)对应的目标分辨率。例如，控制器12判断距离d1落入第一预设距离范围，而所述第一预设距离范围对应的满足所述清晰度要求的分辨率720*1080作为所述目标分辨率。同样的，控制器12判断距离d2落入第二预设距离范围，而所述第二预设距离范围对应的满足所述清晰度要求的分辨率1080*1920作为所述目标分辨率。
此种方式中，控制器12能够针对同属一个距离区间的若干所述距离进行相同目标分辨率的画面显示，由此可以无需对任一所述距离都调整显示屏13的画面精度，避免了显示屏13的画面抖动，保证观看体验。
本实施例中，所述目标分辨率与所述距离呈反比关系，即所述距离越近，所述目标分辨率越高。由此能够满足人眼对近处图像细节的分辨能力较强，对远处图像细节的分辨能力较弱的特性，提高观看体验。例如，距离d1>距离d2，目标分辨率720*1080<目标分辨率1080*1920。
特别的，当所述距离远时，可以通过使得所述目标分辨率小于显示屏13的屏幕分辨率，因此可以减小图像数据量，从而降低显示屏13的功耗。
本实施例的终端设备10，根据人眼到显示屏13的所述距离，调整所述待显示内容的原始分辨率以得到所述目标显示内容，并控制显示屏13全屏显示所述目标显示内容。由于所述目标显示内容的所述目标分辨率与所述距离成反比，在所述距离远时，所述目标分辨率可以较小；在所述距离近时，所述目标分辨率可以较大，由此可以满足人眼对近处图像细节的分辨能力较强，对远处图像细节的分辨能力较弱的特性，符合人机工程学原理，提高了观看体验。并且，当所述距离远时，可以通过使得所述目标分辨率小于所述显示屏的屏幕分辨率，因此可以减小图像数据量，从而降低所述显示屏的功耗。
本实施例中，所述待显示内容的所述原始分辨率可以是大于、等于或小于显示屏13的屏幕分辨率。优选的，本实施例中，所述原始分辨率可以小于或等于显示屏13的屏幕分辨率。即所述目标分辨率可以小于显示屏13的屏幕分辨率。由此，控制器12仅需要向显示屏13发送分辨率小于所述屏幕分辨率的目标显示内容，使得所显示的图像数据量更小，由此进一步的降低了显示屏13的功耗。
本实施例中，优选的，控制器12可以采用Upscaling(图像像素放大)技术来实现显示屏13的全屏显示。例如，对于具有目标分辨率720*1080的所述目标显示内容，采用2.0倍的Upscaling倍增，可以在屏幕分辨率1440*2560的显示屏13上全屏显示。或者，对于具有目标分辨率1080*1920的所述目标显示内容，采用1.3倍的Upscaling倍增，可以在屏幕分辨率1440*2560的显示屏13上全屏显示。Upscaling技术的数据处理速度快、高效，使用成熟。在其他实施例中，还可以采用其他方式实现全屏显示。
本实施例中，距离感测器11可以是红外传感器。红外传感器的红外信号穿透力强，信号失真小，有利于所述距离的精确测定。在其他实施例中，距离感测器11还可以是其他能够测定所述距离的传感装置。

本实施例的显示方法100，根据人眼到显示屏13的所述距离，调整所述待显示内容的原始分辨率以得到所述目标显示内容，并控制显示屏13全屏显示所述目标显示内容。由于所述目标显示内容的所述目标分辨率与所述距离成反比，在所述距离远时，所述目标分辨率可以较小；在所述距离近时，所述目标分辨率可以较大，由此可以满足人眼对近处图像细节的分辨能力较强，对远处图像细节的分辨能力较弱的特性，符合人机工程学原理，提高了观看体验。并且，当所述距离远时，可以通过使得所述目标分辨率小于所述显示屏的屏幕分辨率，因此可以减小图像数据量，从而降低所述显示屏的功耗。
本实施例的显示方法100中，所述待显示内容的所述原始分辨率可以是大于、等于或小于所述显示屏的屏幕分辨率。优选的，所述原始分辨率可以小于或等于所述显示屏的屏幕分辨率。即所述目标分辨率可以小于所述显示屏的屏幕分辨率。由此，仅需要向所述显示屏发送分辨率小于所述屏幕分辨率的的目标显示内容，使得所显示的图像数据量更小，由此进一步的降低了所述显示屏的功耗。
进一步的，在S130中，所述在所述显示屏上全屏显示所述目标显示内容包括：通过图像像素放大Upscaling技术将所述目标显示内容全屏显示在所述显示屏上。例如，对于具有目标分辨率720*1080的所述目标显示内容，采用2.0倍的Upscaling倍增，可以在屏幕分辨率1440*2560的所述显示屏上全屏显示。或者，对于具有目标分辨率1080*1920的所述目标显示内容，采用1.3倍的Upscaling倍增，可以在屏幕分辨率1440*2560的所述显示屏上全屏显示。Upscaling技术的数据处理速度快、高效，使用成熟。在其他实施例中，还可以采用其他方式实现全屏显示。
进一步的，S120中的所述根据所述距离确定所述待显示内容的目标分辨率，并将所述待显示内容的原始分辨率调节为所述目标分辨率，以生成具有所述目标显示分辨率的目标显示内容可以包括：
