Description

距离感测基板、显示装置、显示系统和分辨率调整方法 技术领域
本发明涉及显示技术领域，具体而言，涉及距离感测基板、显示装置、显示系统和分辨率调整方法。
背景技术
高PPI(Pixels Per Inch，每英寸的像素数目)一直是显示领域的一个重要目标，一度成为手机，电视等产品的重要卖点。然而，高PPI带来观看效果好等优点的同时，也带来一些弊端。高PPI会导致GPU(Graphics Processing Unit，图形处理芯片)处理数据增多，从而导致电池耗电大。
实际上人眼的分辨率并不是一成不变的，一般会根据距离，环境，以及图像的运行速度而随时变化。其中一个重要理论就是苹果公司提出的“视网膜”标准，当观看者距离显示屏10-12英寸(约25-30厘米)时，显示屏的分辨率只要达到300ppi(每英寸300个像素点)以上，观看者的视网膜就无法分辨出像素点了，也即不会感觉到颗粒感。
所以当人眼距离手机距离很近时，为了使消费者看不到显示屏的小瑕疵，尽力展现完美的图像，可以用手机本身的高分辨率。但是当屏幕距离用户较远时，即使分辨率不满足上述分辨率，用户也不会分辨出像素点，因此没有必要始终保持显示屏处于一个较高的分辨率而造成过多的电量消耗。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
如图1所示，根据本发明一个实施例的距离感测基板10，包括：
粒子发射器11，用于向观看者发射第一粒子束；
粒子接收器12，用于接收观看者反射的第一粒子束；以及
处理单元13，用于获取发射的第一粒子束的能量密度和接收的第一粒子束的能量密度。
本实施例中的距离感测基板10可以设置在显示装置20的显示屏21上。一般用户观看显示屏21时，人眼距离显示屏21较近(例如观看手机显示屏时一般距离在20cm左右)。由于发射粒子的速度极快，若通过检测发射粒子和接收粒子的时间差来判定距离，该时间差极难确定，因此计算出的距离也不够精确。本实施例通过检测发射的第一粒子束的能量密度和接收的第一粒子束的能量密度来判定距离，相对于检测发射粒子和接收粒子的时间差来判定距离，可以极大地提高判定距离的精确度。
本实施例可以根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度来判断观看者距离显示屏21的观看距离的数值范围，进而根据观看距离所处的数值范围对显示屏21的分辨率进行调整。在用户观看距离较大时，可以适当降低显示屏21的分辨率，这样在保证用户观看效果的前提下降低显示屏的耗电量。
如图2和图3所示，粒子接收器11可以包括：
多条沿第一方向设置的第一导线111和多条沿第二方向设置的第二导线112，多条第一导线111和多条第二导线112交叉界定多个接收区域，其中，多条第一导线111逐条传输扫描信号，每个接收区域包括：
接收电极113，用于接收粒子束，生成激励电流；
开关薄膜晶体管114，在相应的第一导线111传输扫描信号时将接收电极113与相应的第二导线导通，以使接收电极113生成的激励电流传输至相应的第二导线112。
在本实施例中，粒子接收器12的结构与显示装置20中阵列基板的结构相似，粒子接收器12可以为平面状，以便接收入射的粒子束。
如图4所示，所述距离感测基板还可以包括：
多条栅线和多条数据线，多条栅线和多条数据线交叉界定多个像素区域，每个像素区域包括驱动薄膜晶体管24。
在本实施例中，距离感测基板10除了能够发射和接收第一粒子束来实现距离检测的相关功能，还可以通过栅极、数据线和驱动薄膜晶体管等结构实现显示驱动的功能。当将距离感测基板10设置在显示装置20中时，距离感测基板10一方面可以作为显示装置20的距离传感器实 现距离检测的相关功能，另一方面可以作为显示装置20的阵列基板实现显示驱动的相关功能，从而提高了距离感测基板10中相关功能模块的集成度。
多条第一导线111与多条栅线在距离感测基板10基底的投影重合，多条第二导线112与多条数据线在距离感测基板10基底的投影重合，开关薄膜晶体管114与驱动薄膜晶体管24在距离感测基板10基底的投影重合。
本实施例中，当距离感测基板10同时实现显示驱动和距离检测的相关功能时，可以使得多条第一导线111和多条第二导线112不会对像素区域造成遮挡，从而不会对像素区域的开口率造成影响。
进一步地，还可以设置开关薄膜晶体管114与驱动薄膜晶体管24在距离感测基板10基底的投影重合，使得开关薄膜晶体管114不会对像素区域的开口率造成影响。
每个像素区域还可以包括像素电极25，
多条第一导线111形成在多条栅线之上，多条第二导线112形成在多条数据线之上，开关薄膜晶体管114形成在驱动薄膜晶体管24之上，接收电极113形成在像素电极25之上。
在本实施例中，可以在形成驱动薄膜晶体管24和像素电极25之后，继续形成多条第一导线111、多条第二导线112、开关薄膜晶体管114以及接收电极113，使得距离感测基板10实现显示驱动相关功能的结构层和实现距离检测相关功能的结构层能够形成在一个整体的结构中，从而提高了距离感测基板10的集成度，降低了距离感测基板10的厚度。
当然，也可以根据需要分别制作实现显示驱动相关功能的结构层和实现距离检测相关功能的结构层，然后将两部分结构层进行贴合。
第一粒子束可以为红外光。
通过发射和接收红外光线测距，一方面由于红外光线为不可见光，可以避免对用户的观看造成干扰；另一方面由于红外光线相对于紫外光对人体损伤要小得多，因此可以在完成测距判定的同时保证对人体损伤最小化。
第一粒子束可以为电子束。
通过发射和接收电子束测距，一方面由于人眼无法观测到电子束，可以避免对用户的观看造成干扰；另一方面由于电子束的能量密度较 大，在经过观看者面部反射后仍能够具有较高的能量密度，便于接收以及提高后续计算精度。
如图5所示，本发明还提出了一种显示装置20，包括显示屏21，还包括：
上述距离感测基板10；
调整单元22，根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度调整显示屏21的分辨率。
本实施例可以根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度来判断观看者距离显示屏21的观看距离的数值范围，进而根据观看距离所处的数值范围对显示屏21的分辨率进行调整。在用户观看距离较大时，可以适当降低显示屏21的分辨率，从而在保证用户观看效果的前提下降低显示屏的耗电量。
处理单元13根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度，获得观看者距离显示屏的观看距离。
调整单元22根据观看距离调整显示屏的分辨率。
例如接收的第一粒子束的能量密度为I，I＝AI0e-μH。
其中，I是第一粒子束在介质中传播后入射到显示屏11的能量密度，I0是出射的粒子束的能量密度；e是自然对数的底数；μ是光子的线性衰减系数，H是观看距离。
从而可以得出H＝-(1/μ)*ln(I/AI0)。
如图6所示，处理单元13还用于获取第一粒子束的出射位置以及第一粒子束在显示屏上的入射位置，以获得出射位置到入射位置的第一距离，根据第一粒子束衰减的能量密度获得第一粒子束传播的第二距离，根据第一距离和第二距离获得观看距离。
处理单元13还用于根据传输扫描信号的第一导线111和传输激励电流的第二导线112确定第一粒子束的入射位置。
粒子束的出射位置可以根据粒子发射器11的位置确定。粒子束的出射位置、入射位置和粒子束在观看者面部的反射点可以构成一个三角形，并且一般在观看者正视显示屏21时，电子束出射点到反射点的距离和反射点到入射点的距离近似相等。
也即上述三角形一般情况下可以近似为等腰三角形，其中第一距离D为等腰三角形的底边长度，第二距离L为等腰三角形两条腰的长度之 和，而观看距离H则为等腰三角形的高。根据勾股定理可以得到H2+(D/2)2＝(L/2)2，进而可以得出观看距离H。
根据本实施例计算得出的观看距离是用户距离显示屏21的垂直距离，更接近用户距离显示屏21的实际距离。
处理单元13根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度，获得第一粒子束衰减的能量密度，
若衰减的能量密度大于第一预设值，则判定观看距离大于第一数值，
若衰减的能量密度小于第二预设值，则判定观看距离小于第二数值，
调整单元22根据观看距离调整显示屏的分辨率。
本实施例无需计算出具体的观看距离，可以直接根据第一粒子束衰减的能量密度来判断观看距离与第一数值和第二数值的关系，从而进行调整操作，简化了计算步骤，提高了判断速度。
需要说明的是，上述实施例中距离感测基板10发射和接收粒子束，以及计算能量密度的操作可以按照预设周期进行，避免频繁计算而导致过多电量消耗。
调整单元22可以在观看距离大于第一数值时，降低显示屏的分辨率。
当观看距离较大时(大于第一距离)，用户对于像素点的分辨能力会降低，因此可以将显示屏21的分辨率降低，从而在保证用户观看效果的前提下实现节约电能。
调整单元22可以在观看距离小于第二数值时，提高显示屏的分辨率。
当观看距离较小时(小于第二距离)，用户对于像素点的分辨能力会提高，因此可以将显示屏21的分辨率提高，从而保证用户的观看效果。
需要说明的是，第二距离小于第一距离。当观看距离在第二距离至第一距离之间时，可以维持显示屏21以正常分辨率显示图像。
显示装置还可以包括：
人脸识别单元23，用于识别观看者的面部是否朝向显示屏，
其中，调整单元22在观看者的面部没有朝向显示屏时降低显示屏 的分辨率。
当观看者没有面向显示屏11时，说明用户没有观看显示屏，或者正侧视显示屏11。若用户没有观看显示屏11，则可以降低分辨率以节约电能，若用户侧视显示屏11，相对于正视显示屏11时对像素点的分辨能力也会降低，因此也可以降低分辨率来节约电能。
如图7所示，本发明还提出了一种显示系统30，包括上述显示装置20，还包括：
穿戴设备31，在粒子发射器11未发射第一粒子束时，用于向显示装置20发射第二粒子束，
其中，处理单元13还用于检测接收的第二粒子束的能量密度，调整单元还用于根据接收的第二粒子束的能量密度调整显示屏21的分辨率。
用户可以穿戴与显示装置20配套的穿戴设备31。通过该穿戴设备31向显示装置发射第二粒子束，无需显示装置20自身发射第一粒子束，进一步提高显示装置20的续航能力。其中穿戴设备31可以是智能眼镜、智能头环、智能耳机等。
上述实施例中的显示装置20可以为：电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
如图8所示，本发明还提出了一种基于上述显示装置的分辨率调整方法，包括：
S1，向观看者发射第一粒子束；
S2，接收观看者反射的第一粒子束；
S3，根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度调整显示屏的分辨率。

S312，根据第一粒子束衰减的能量密度获得第一粒子束传播的第二距离；
S313，根据第一距离和第二距离获得观看距离。
如图11所示，根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度调整显示屏的分辨率包括：
S31’，根据发射的第一粒子束的能量密度和接收的第一粒子束的能量密度，获得第一粒子束衰减的能量密度，
S32’，若衰减的能量密度大于第一预设值，则判定观看距离大于第一数值，
S33’，若衰减的能量密度小于第二预设值，则判定观看距离小于第二数值。
调整显示屏的分辨率可以包括：
在观看距离大于第一数值时，降低显示屏的分辨率。
调整显示屏的分辨率可以包括：
在观看距离小于第二数值时，提高显示屏的分辨率。
分辨率调整方法还可以包括：
识别观看者的面部是否朝向显示屏，在观看者的面部没有朝向显示屏时降低显示屏的分辨率。
如图12所示，本发明还提出了一种基于上述显示系统的分辨率调整方法，包括：
A1，向显示装置发射第二粒子束；
A2，显示装置检测接收的第二粒子束的能量密度；
A3，根据接收的第二粒子束的能量密度调整显示屏的分辨率。
以上结合附图详细说明了本发明的技术方案，考虑到现有技术中，显示图像时始终保持在一个较高的分辨率，造成电量的浪费。通过本发明的技术方案，可以根据观看者距离显示屏的观看距离来调整显示屏的分辨率，在用户观看距离较大时，适当降低显示屏的分辨率，从而在保证用户观看效果的前提下降低显示屏的耗电量。
在本发明中，术语“第一”、“第二”仅用于描述目的，而不应当理解为指示或暗示相对重要性。术语“多个”指两个或两个以上，除非 另有明确的限定。
以上所述仅为本发明的优选实施例，并不用于限制本发明。对于本领域的技术人员来说，本发明可以有各种修改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
