Description

一种终端及终端显示亮度调节的方法 技术领域
本发明涉及电子设备应用领域，特别涉及一种终端及终端显示亮度调节的方法。
背景技术
随着科技的发展和技术的进步，触控显示面板已经广泛应用在需要人机交互接口的装置中，如工业计算机的操作屏幕、平板计算机、智能手机的触控屏幕等等。当用户接听到电话时，终端屏幕如果还是保持使用状态下的亮度，将导致终端功耗进一步增大，使得终端电量快速耗尽，不利于用户的感官体验。因而在用户接听电话时，对终端的显示亮度自动进行调节就显得尤为必要。
目前，现有技术中对终端的显示亮度进行调节的方式主要有以下几种：
一种是通过增设语音模块的方式，通过声控方式用以替代光感传感器进行终端屏幕的亮度调节。如申请号为“201610511375.3”的申请文件中公开了一种终端，包括微处理器、音频输出单元、声音传感器和显示屏；音频输出单元，用于输出声音信号；声音传感器，用于在采集到音频输出单元输出的声音信号的反射声音信号时，向微处理器发送显示调整指令；微处理器，用于在接收到显示调整指令且确定终端处于通话状态时，对显示屏的亮度进行调节。这个方案一方面要求终端需要额外增设声音传感器，增加终端成本；另一方面依然需要用户通过声音来触发对显示亮度的调节，本质上与用户手动调节差异不是很大，无法实现在用户接听电话时对屏幕显示亮度进行自动调整。
另一种是通过感知终端与遮挡物体之间的距离，来实现对终端亮度的调节。如申请号为“201610627457.4”的申请文件中公开了一种基于近距离传感器实现音量和亮度调节的方法及系统，所述方法包括：移动终端中近距离传感器获取遮挡物体到触摸屏之间的距离，并判断所述距离值是否在预设的距离范围内； 当判断所述距离值在预设的距离范围内时，根据预设的距离范围与移动终端参数的对应关系，将移动终端参数值调节至与所述距离值对应的参数；所述移动终端参数包括：音量、屏幕亮度以及闪光灯亮度。这一方案首先要在终端上增设距离传感器，改变了终端原有的结构且增加了成本；另一方面对于遮挡物体并没有明显的界定，即任何物体只要与终端距离足够近，就会启动对屏幕亮度的调整，这往往容易导致误操作现象，且无法适用于用户在接听电话时麦克风模式需求。
综上所述，提供一种不改变终端原有架构、且无论终端处于何种接听模式下均能自适应调整手机屏幕亮度，以达到节省功耗、提高用户体验效果的方案就显得尤为必要。

采用以上技术方案后的有益效果为：通过在显示单元的特征识别区下方设置传感单元，当终端接收到来电时，只要捕捉到用户的特征信息，并将其与亮度配置信息中的特征信息进行比较，若匹配则其对显示亮度的调整。相较于语音识别的方式，用户只要将靠近特定部位进行特征捕捉，即可对屏幕亮度进行调整，无需用户额外进行输入语音，有效提升了用户感官体验；同时，本发明的显示单元直接设置于显示单元下方，无需额外增设传感器(如距离传感器)有效缩小移动设备的整体厚度，使得移动设备更加轻薄、满足市场的需求。通过捕捉用户的特征信息进行比对的方式来实现对显示亮度的调整，可以避免用户误操作，也提高了屏幕亮度调整的准确度。

具体实施方式
为详细说明本发明的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
请参阅图1，为本发明一实施方式涉及的终端显示亮度调节的方法的流程图。所述方法应用于终端，所述终端为具有触摸显示屏的电子设备，如是手机、平板电脑、个人数字助理等智能移动设备，还可以是个人计算机、工业装备用计算机等电子设备。
所述终端包括显示单元和传感单元，所述显示单元上设置有特征识别区，所述传感单元位于所述特征识别区的下方，用于捕捉用户的特征信息。所述显示单元乃是以有源阵列薄膜晶体管作为扫描驱动与传输数据的显示屏，包括AMOLED显示屏、LCD液晶显示屏、微发光二极管显示屏、量子点显示屏、或是电子墨水显示屏；在其他实施方式中，显示单元也可以为其他具有显示功能的电子元件。所述方法包括以下步骤：
首先进入步骤S101预先设置亮度配置信息。所述亮度配置信息包括用户特征信息与显示亮度的对应关系。在本实施方式中，所述特征信息包括人脸特征信息、指纹特征信息、人耳特征信息、嘴唇特征信息中的一种或多种。优选的，所述人脸特征信息为人脸模板轮廓信息，这样当传感单元捕捉到的图像中具有一大致的人脸头像时，无需进行细节特征的比对，即可完成对屏幕显示亮度的调整，从而使得对显示单元亮度的调整更加便捷，适应自动快速调节的需求。 人耳特征信息、嘴唇特征信息同理可得，此处不再赘述。
亮度配置信息的显示亮度即为用户事先录入存储的显示亮度，每一个用户特征信息对应一显示亮度，每一显示亮度可以与多个用户特征信息相对应。亮度配置信息可以存储于终端的存储单元，如手机的内存、计算机的硬盘中，也可以存储于服务器的存储单元中，当需要获取亮度配置信息时，只需让终端与服务器建立通讯连接，而后再从服务器获取到事先存储的亮度配置信息，所述通讯连接包括有线通讯连接或无线通信连接。
而后进入步骤S102捕捉用户的特征信息。在本实施方式中，传感单元的覆盖的范围与显示单元的大小相适配，优选的，传感单元的形状为矩形，矩形的大小位于显示单元的中心。当然在另一些实施例中，传感单元还可以为多个，只需满足多个传感单元拼接成与显示单元相适配的大小、并置于显示单元的下方即可。
而后进入步骤S103判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配，若是则进入步骤S104将当前终端的显示亮度调整为该亮度配置信息中的特征信息对应的显示亮度，否则进入步骤S105不对终端的显示亮度进行调整。用户特征信息的比对可以通过特征信息识别算法来实现，相关的特征信息识别算法可以事先存储于终端的存储单元中。以特征信息为指纹信息为例，当传感单元获取到特征识别区上的用户的指纹信息后，终端的处理器将调用存储单元中的指纹识别算法，将所获取的指纹信息与亮度配置信息中的指纹信息进行比对，判断两者是否匹配。纹识别算法包括对指纹图像进行预处理、数据特征提取、特征匹配、指纹识别等步骤，可以用多种算法来实现，这些算法都是成熟的现有技术，现已被应用于各个加密解密领域，此处不再展开赘述。
请参阅图2，为本发明另一实施方式涉及的终端显示亮度调节的方法的流程图。所述步骤“预先设置亮度配置信息”包括：
首先进入步骤S201接收用户设置指令，显示特征识别区。设置指令可以通过用户点击屏幕上设置栏中的某一按钮触发，终端接收到设置指令后，将对特 征识别区进行显示，便于用户将待输入的特征信息对准特征识别区以便传感单元捕捉。在本实施方式中，显示特征识别区可以包括：提高特征识别区的亮度或在特征识别区上显示一提示输入框。在某些实施例中，在接收用户设置指令之前，还包括接收用户的账号信息，所述账号信息包括用户ID及密码。用户需要以语音控制、眼球控制、或是按键密码控制等方式输入正确的用户ID及密码，登录用户账号后，才可触发所述设置指令，这样一方面可以提高亮度配置信息设置的安全性，另一方面也可以达到在一个终端上区分不同用户、保存不同的亮度配置信息的效果。
而后进入步骤S202捕捉用户在设置过程中的特征信息并保存。在本实施方式中，所述终端包括存储单元，所述步骤S202包括：判断置过程中所捕捉到的用户特征信息是否已存储于存储单元，当判定为是时提示用户该特征信息已录入；当判定为否时将该特征信息保存至存储单元。这样可以有效避免特征信息的重复录入。
而后进入步骤S203显示一显示亮度信息列表，接收用户对显示亮度信息的选择指令，建立所选中的显示亮度信息与所捕捉的用户在设置过程中的特征信息的对应关系并保存。选择指令可以通过用户点击勾选、双击等方式触发。所述显示亮度信息列表中包含着一个或多个显示亮度对信息，每一显示亮度信息对应一显示亮度值，显示亮度信息可以以文字或图片的形式予以显示，还可以是通过滑动横条的方式予以呈现，当接收到用户对横条的滑动指令时，可以随即调整终端的显示亮度，以便用户直观设置当前录入的特征信息所要调整的显示亮度。
在某些实施例中，当终端处于接听模式时，所述特征信息为人耳特征信息，所述人耳特征信息包括耳朵轮廓信息。所述接听模式是区别于麦克风模式而言，未进行外放音量的听筒模式。在接听模式下，用户一般是通过将终端靠近耳部以接听来电者的音频。所述步骤“捕捉用户的特征信息，判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”包括：捕捉用户耳朵轮廓信息，判 断捕捉到的耳朵轮廓信息与亮度配置信息中的耳朵轮廓信息是否匹配。当终端靠近人体耳部时，置于显示单元之下的传感单元可以捕捉到耳部图像或者识别到由远及近、逐渐变大的耳朵轮廓的多帧图像，通过将传感单元所捕捉的图像与预设的耳朵轮廓信息进行匹配，以判断当前用户是不是处于接听模式，若是则可以对当前终端的屏幕显示亮度进行调整。优选的，所述“对当前终端的屏幕显示亮度进行调整”包括：尽可能地将当前终端的显示亮度调暗，以达到节省功耗的目的。
在某些实施例中，当终端处于麦克风模式时，所述特征信息为指纹特征信息，所述麦克风模式通过用户点击第一按钮触发。所述麦克风模式即为音量外放模式。目前，终端在接收到来电或语音时，通常会在显示屏上显示出多个操作按钮，当用户点击第一按钮(如屏幕上显示的“扬声器”按钮)，则触发麦克风模式。所述步骤“捕捉用户的特征信息，判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”包括：接收到用户对所述第一按钮的点击指令时，捕捉用户的指纹特征信息，判断捕捉到的指纹特征信息与亮度配置信息中的指纹特征信息是否匹配。由于传感单元设置在显示屏的下方，因而当接收到用户对第一按钮点击时，可以同步采集用户的指纹信息，从而实现在麦克风模式下对终端显示亮度的调整，达到节省功耗的目的。
在另一些实施方式中，当终端处于麦克风模式时，所述特征信息还可以为人脸特征信息或嘴唇特征信息，所述人脸特征信息包括人脸特征轮廓信息，所述嘴唇特征信息包括嘴唇特征轮廓信息。用户可以在终端处于麦克风模式时，将人体脸部或嘴唇部位对准屏幕，以触发传感单元对人脸特征轮廓信息或嘴唇特征轮廓信息的采集，进而在采集到的信息匹配成功后执行对终端显示亮度的调整，以达到节省麦克风模式下功耗的目的。
在某些实施例中，所述“判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”包括：判断捕捉到的特征信息与亮度配置信息中的特征信息的匹配度是否达到预设百分比，若是则判定为相匹配，否则判定为不匹配。所述 特征信息包括多个特征项，所述匹配度可以通过对不同的特征项设置不同的权重值，并进行累加计算得出。以特征信息为人脸信息为例，对人脸识别除了识别出人脸轮廓，还包括眼睛、嘴唇等部位的定位识别。在实际应该过程中，可以将人脸轮廓的权重值设置的较大，而眼睛、嘴唇等部位的权重值设置较小，将各个特征项(人脸轮廓、眼镜、嘴唇等)的匹配度(与预设值比相差程度越小，匹配度越高，可以用一数值界定)乘以各个特征项对应的权重值，得到最终特征信息对应的匹配度，并将匹配度与预设百分比进行比较，进而判断出当前特征信息是否与亮度配置信息中的特征信息相匹配。
在某些实施例中，所述方法还包括步骤：当判定捕捉到的特征信息与亮度配置信息中的特征信息不匹配时，发出提示信息。所述提示信息包括声音提示信息、图像提示信息、光线提示信息、视频提示信息中的一种或多种。所述声音提示信息包括提示用户“当前捕捉到的特征信息与亮度配置信息中的特征信息不匹配”的语音提示信息，所述图像提示信息包括提示用户“当前捕捉到的特征信息与亮度配置信息中的特征信息不匹配”的弹窗提示信息，所述视频提示信息包括提示再次将特征信息部位对准屏幕以使传感单元可以捕捉到用户特征信息的动画提示信息，光线提示信息包括改变屏幕亮度或者让显示屏发出不同颜色的光线等。
为了进一步节省功耗，不仅可以在终端响应某一事件(如接听到来电)时，对终端的屏幕亮度进行调整，还可以相应地适当降低音量大小。因而在某些实施例中，所述方法还包括步骤：预先设置音量配置信息，所述音量配置信息包括用户特征信息与音量大小的对应关系，所述步骤“判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”之后还包括：若是则将当前终端的音量调整为该音量配置信息中的特征信息对应的音量大小，否则不对终端的音量进行调整。
在某些实施例中，所述传感单元包括光侦测感应层，所述光侦测感应层用于在接收到光源触发信号时，自显示单元的显示像素发出预设图案的光源，以 及用于在接收到侦测触发信号时，处于光信号侦测状态，并接收用户特征部位反射的影像信号以捕捉用户的特征信息。所述预设图案可以根据当前终端接收到的某一事件来触发，例如事件为来电，则显示屏上可以显示一电话或听筒图案呈现给用户。进一步地，传感单元的开启或关闭，可以依据终端是否正在响应一事件而确定，例如可以在终端接收到来电提醒时，将传感单元开启；而在终端未接收到来电提醒时，将传感单元关闭。从而有效避免用户误操作现象。
如图5所示，在某些实施例中，所述传感单元包括TFT影像感测阵列薄膜，所述光侦测感应层为光敏二极管所形成的阵列。液晶显示(LCD)面板或有机发光二极管(OLED)显示面板，皆是以TFT结构驱动扫描单一像素，以实现面板上像素阵列的显示功能。形成TFT开关功能的主要结构为金属氧化物半导体场效晶体管(MOSFET)，其中熟知的半导体层材料主要有非晶硅、多晶硅、氧化铟镓锌(IGZO)、或是混有奈米碳材料之有机化合物等等。由于光感测二极管的结构亦可采用此类半导体材料制备，且生产设备也兼容于TFT阵列的生产设备，因此近年来TFT光侦测二极管开始以TFT阵列制备方式进行生产。本实施方式所述的TFT影像感测阵列薄膜即为上述提到的TFT光侦测二极管(如图4中的光感测二极管区域部分)，具体结构可以参考美国专利US6943070B2、中华人民共和国专利CN204808361U中对传感单元结构的描述。TFT影像感测阵列薄膜的生产工艺与显示面板TFT结构不同的是：原本在显示面板的像素开口区域，在生产工艺上改为光感测区域。其TFT制备方式可以采用薄型玻璃为基材，亦可采用耐高温塑性材料为基材，如美国专利US6943070B2所述。
为了使得在黑暗环境下也可以实现对终端屏幕亮度的调整，在某些实施例中，所述光敏二极管为红外光敏二极管，所述红外光敏二极管包括红外感应层，所述红外感应层可用于感知红外信号，以便传感单元在黑暗环境下也可以捕捉到用户的特征信息，进而实现对终端屏幕亮度的调整。图5所示的传感单元易受周围环境光或者显示屏像素所发出的可见光的反射、折射等因素影响，造成光学干扰，严重影响内嵌于显示面板下方的TFT影像感测阵列薄膜的信号噪声 比(SNR)，为了提高信号噪声比，可以对图5所示的传感单元的基础上做了进一步改进，使得TFT影像感测阵列薄膜可以侦测识别用户特征信息的红外信号。
如图6所示，为了将TFT影像感测阵列薄膜能够识别的光信号波长从可见光范围扩展至红外光范围，对图5的TFT影像感测阵列薄膜进行改进，具体是采用红外光敏二级管替换图5中TFT影像感测阵列薄膜的光二极管层，红外光敏二极管包括微晶硅光电二极管或非晶硅化合物光电二极管。
实施例一：将非结晶硅p型/i型/n型光电二极管结构(图5中的光二极管层)改由微晶硅p型/i型/n型光电二极管结构。在此实施例中，光电二极管的微结晶程度主要是在化学气象沉积过程中，以适当氢气浓度混入气体硅烷(SiH4)去控制氢原子键结非晶硅之悬空键(dangling bond)，以实现微晶硅p型/i型/n型光电二极管结构之镀膜。藉由调整化学气象沉积的氢气浓度，微晶光电二极管的操作波长范围可以扩展到光波长600nm到1000nm的范围。
在采用微晶光电二极管之实施例中，为了进一步地提高光电转换之量子效率，微晶硅光电二极管也可采用双结以上p型/i型/n型结构串接形成。该光电二极管第一结层p型/i型/n型材料仍然为非结晶结构，第二结层以上p型/i型/n型材料可以为微晶结构、多晶结构。
实施例二：将非结晶硅p型/i型/n型光电二极管结构(图5中的光二极管层)改为掺有可扩展光敏波长范围之非结晶硅化合物之p型/i型/n型光电二极管结构，优选之化合物实施例为非晶硅化锗。在此实施例中，光电二极管的本质层(i型)在以化学气象沉积镀膜过程中，通以气体锗烷(GeH4)混入硅烷(SiH4)，以实现非结晶硅化锗p型/i型/n型光电二极管之光敏范围达到光波长600nm到1000nm的范围。
在采用非结晶硅化合物光电二极管之实施例中，为了提高光电转换之量子效率，非晶硅光电二极管也可采用双结以上p型/i型/n型结构串接形成。该光电二极管第一结层p型/i型/n型材料仍然为非晶硅结构，第二结层以上p型/i型/n型材料可以为微晶结构、多晶结构或是掺有可扩展光敏波长范围之化合物 材料。
当红外感应层为红外光敏二级管所形成的阵列时，在实际应用过程中，可藉由TFT作扫描驱动外加一偏压(包括正向偏压，或零偏压或负偏压)在p型/i型/n型光电二极管之间，实现TFT影像感测阵列薄膜发出红外光功能，
在某些实施例中，第一触发信号可以通过在p型/i型/n型红外光敏二极管之间施加正向偏压触发，第二触发信号可以通过在p型/i型/n型红外光敏二极管之间施加零偏压或负偏压触发。例如红外光敏二极管所形成的阵列假设有10列(假设编号为1-10)，那么可以对编号为奇数的像素点阵列施加正向偏压，以使得奇数列像素点阵列可发出红外光信号，并对编号为偶数的像素点阵施加零偏压或负偏压，以使得偶数列像素点阵列处于侦测红外光状态，以捕捉用户特征信息所在的部位反射回的红外光并转换为红外图像加以输出。当然，在另一些实施例中，第一触发信号可以通过在p型/i型/n型红外光敏二极管之间施加零偏压或负偏压触发，第二触发信号可以通过在p型/i型/n型红外光敏二极管之间施加正向偏压触发。所述第一触发信号可以为光源触发信号，所述第二触发信号可以为侦测触发信号；当然，第一触发信号也可以为侦测触发信号，所述第二触发信号可以为光源触发信号。
在某些实施例中，还可以交替在p型/i型/n型红外光敏二极管之间施加正向偏压，或零偏压或负偏压，以触发所述第一触发信号或第二触发信号。同样以红外光敏二极管所形成的阵列有10列像素点阵为例，在第一周期内对p型/i型/n型红外光敏二极管施加正向偏压，使得10列像素点阵均处于发出红外光状态；在第二周期内对p型/i型/n型红外光敏二极管施加零偏压或负偏压，使得10列像素点阵均处于红外光侦测状态，用于捕捉用户特征信息部位反射回的红外光信息，并生成相应的红外图像输出；在第三周期内又对p型/i型/n型红外光敏二极管施加正向偏压，使得10列像素点阵均处于发出红外光状态，反复交替，以此类推。光源触发信号(第一触发信号)与侦测触发信号(第二触发信号)交替切换，并符合一预设频率。相邻的周期之间的时间间隔可以根据实际 需要而设置，优选时间间隔可以设置为TFT阵列驱动扫描每一帧(Frame)红外光敏二极管阵列至少能接收到一帧完整的影像信号所需的时间，即预设频率为每经过上述时间间隔进行一次切换。
在某些实施例中，当所述显示单元为LCD液晶显示屏时，所述传感单元的下方还设置有背光单元，所述传感单元设置于背光单元和LCD液晶显示屏之间。由于LCD液晶显示屏不属于自发光元件，因而在安装时需要在传感单元的下方增加背光单元。背光单元可以为LCD背光模组，也可以为其他具有自发光功能的电子元件。在另一些实施例中，当所述显示单元为AMOLED显示屏时，由于OLED显示屏属于自发光元件，因而无需设置背光单元。通过上述两种方案的设置，可以有效满足不同厂家的生产需求，提高终端的适用范围。
在某些实施例中，所述特征识别区包括多个特征识别子区域，每一特征识别子区域的下方对应设置一传感单元。所述终端还包括传感单元控制电路，所述方法还包括：接收用户对特征识别子区域的启动指令，传感单元控制电路开启所述特征识别子区域的下方的传感单元，以及接收用户对特征识别子区域的关闭指令，传感单元控制电路关闭所述特征识别子区域的下方的传感单元。
以光侦测感应区的数量为两个为例，两个光侦测感应子区域可以一上一下或一左一右均匀分布于屏幕中，也可以以其他排列方式分布于屏幕中。下面对具有两个光侦测感应子区域的终端的应用过程做具体说明：在使用过程中，接收用户触发的启动信号，将两个光侦测感应子区域下方的光侦测器件都设置成开启状态。优选的实施例中，两个光侦测感应子区域构成的范围覆盖了整个显示屏，这样可以保证当两个光侦测感应子区域下方的光侦测器件都设置成开启状态时，进入显示屏的光信号可以被下方的TFT影像感测阵列薄膜(即光侦测器件)所吸收，从而捕捉到用户的特征信息。
在其他实施例中，两个光侦测感应子区域构成的范围也可以占整个显示屏面积的2/3、3/4等。当然，用户也可以根据自身喜好，设置某一个光侦测感应子区域下方的光侦测器件开启，另一个光侦测感应子区域下方的光侦测器件关闭。 在不需要对终端进行操作时，还可以将两个光侦测感应子区域下方的光侦测器件均设置为关闭状态。简言之，各个光侦测感应子区域下方的光侦测器件下方处于开启或关闭，可以根据用户自身喜好进行设置。
请参阅图3，为本发明一实施方式涉及的终端的示意图。所述终端包括显示单元101和传感单元102，所述显示单元101上设置有特征识别区，所述传感单元102位于所述特征识别区的下方，用于捕捉用户的特征信息；所述终端还包括配置信息设置单元104、判断单元107和处理单元106；

所述传感单元102用于捕捉用户的特征信息，所述判断单元107用于判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配，若是则处理单元106用于将当前终端的显示亮度调整为该亮度配置信息中的特征信息对应的显示亮度，否则处理单元106不对终端的显示亮度进行调整。所述特征信息包括人脸特征信息、指纹特征信息、人耳特征信息、嘴唇特征信息中的一种或多种。在某些实施例中，所述终端还包括操作指令接收单元105，所述“配置信息设置单元用于预先设置亮度配置信息”包括：所述操作指令接收单元105用于接收用户设置指令，显示特征识别区；所述传感单元102用于捕捉用户在设置过程中的特征信息并保存；所述显示单元101用于显示一显示亮度信息列表，所述操作指令接收单元用于接收用户对显示亮度信息的选择指令，所述处理单元106用于建立所选中的显示亮度信息与所捕捉的用户在设置过程中的特征信息的对应关系并保存。亮度配置信息可以存储于终端的存储单元108，如手机的内存、计算机的硬盘中，也可以存储于服务器的存储单元中，当需要获取亮度配置信息时，只需让终端与服务器建立通讯连接，而后再从服务器获取到事先存储的亮度配置信息，所述通讯连接包括有线通讯连接或无线通信连接。
在某些实施例中，当终端处于接听模式时，所述特征信息为人耳特征信息，所述人耳特征信息包括耳朵轮廓信息；“传感单元用于捕捉用户的特征信息，所 述判断单元用于判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”包括：传感单元用于捕捉用户耳朵轮廓信息，所述判断单元用于判断捕捉到的耳朵轮廓信息与亮度配置信息中的耳朵轮廓信息是否匹配。

在某些实施例中，所述“判断单元用于判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配”包括：判断单元用于判断捕捉到的特征信息与亮度配置信息中的特征信息的匹配度是否达到预设百分比，若是则判定为相匹配，否则判定为不匹配。
在某些实施例中，所述处理单元还用于在判断单元判定捕捉到的特征信息与亮度配置信息中的特征信息不匹配时，发出提示信息。所述提示信息包括声音提示信息、图像提示信息、光线提示信息、视频提示信息中的一种或多种。
在某些实施例中，所述配置信息设置单元还用于预先设置音量配置信息，所述音量配置信息包括用户特征信息与音量大小的对应关系；所述判断单元还用于判断捕捉到的特征信息与亮度配置信息中的特征信息是否匹配，若是则处理单元用于将当前终端的音量调整为该音量配置信息中的特征信息对应的音量大小，否则处理单元不对终端的音量进行调整。
在某些实施例中，所述传感单元包括光侦测感应层，所述光侦测感应层用于在接收到光源触发信号时，自显示单元的显示像素发出预设图案的光源，以及用于在接收到侦测触发信号时，处于光信号侦测状态，并接收用户特征部位反射的影像信号以捕捉用户的特征信息。优选的，所述传感单元包括TFT影像 感测阵列薄膜，所述光侦测感应层为光敏二极管所形成的阵列。光源触发信号与侦测触发信号交替切换，并符合一预设频率。
在某些实施例中，所述显示单元乃是以有源阵列薄膜晶体管作为扫描驱动与传输数据的显示屏，包括AMOLED显示屏、LCD液晶显示屏、微发光二极管显示屏、量子点显示屏、或是电子墨水显示屏。如图4所示，当所述显示单元为LCD液晶显示屏时，所述传感单元的下方还设置有背光单元，所述传感单元设置于背光单元和LCD液晶显示屏之间。
在某些实施例中，所述特征识别区包括多个特征识别子区域，每一特征识别子区域的下方对应设置一传感单元。所述终端还包括传感单元控制电路，所述操作指令接收单元用于接收用户对特征识别子区域的启动指令，所述传感单元控制电路用于开启所述特征识别子区域的下方的传感单元，以及所述操作指令接收单元用于接收用户对特征识别子区域的关闭指令，所述传感单元控制电路用于传感单元控制电路关闭所述特征识别子区域的下方的传感单元。
本发明的有益效果为：通过在显示单元的特征识别区下方设置传感单元，当终端接收到来电时，只要捕捉到用户的特征信息，并将其与亮度配置信息中的特征信息进行比较，若匹配则其对显示亮度的调整。相较于语音识别的方式，用户只要将靠近特定部位进行特征捕捉，即可对屏幕亮度进行调整，无需用户额外进行输入语音，有效提升了用户感官体验；同时，本发明的显示单元直接设置于显示单元下方，无需额外增设传感器(如距离传感器)有效缩小移动设备的整体厚度，使得移动设备更加轻薄、满足市场的需求。通过捕捉用户的特征信息进行比对的方式来实现对显示亮度的调整，可以避免用户误操作，也提高了屏幕亮度调整的准确度。
