- fingerprint recognition technology has been widely used in terminal equipment.
- the optical fingerprint recognition technology is especially favored by manufacturers due to its excellent recognition performance. Therefore, more and more terminal devices are equipped with optical fingerprint modules.
- the light emitted by the display screen 101 passes through the optical adhesive layer 102 and then exits through the transparent cover plate 103. Due to the difference in the optical refractive index between the skin 104 and the air, between the skin 104 and the transparent cover plate 103 The reflectivity is low, and the interface between the air and the light-transmitting cover 103 has a high reflectivity.
- the above-mentioned light with different reflectivity can be captured by the optical fingerprint module 105 to form a fingerprint image.
- the brightness of the display screen 101 is insufficient, especially in a high-brightness environment, the light reflected by the skin 104 of the finger to the optical fingerprint module 105 is weak, which affects the fingerprint recognition performance, resulting in optical fingerprints
- the recognition speed of the module 105 is slow, or even cannot be recognized.
- the present disclosure discloses a terminal device to solve the problem that fingerprint recognition is slow or even unrecognizable due to poor display brightness of the terminal device.
- a terminal device includes a display screen, a light-transmitting light supplement device, and an optical fingerprint module
- the display screen includes a fingerprint recognition area
- the display screen is arranged on the optical fingerprint module
- the optical fingerprint module is connected to
- the fingerprint identification area is arranged oppositely
- the light-transmitting and supplementary light device is arranged opposite to the fingerprint identification area.
- the terminal device disclosed in the embodiment of the present disclosure adds a light-transmitting light-filling device, and the light-transmitting light-filling device is arranged opposite to the fingerprint recognition area. Therefore, it can project the light fill light to the fingerprint recognition area, and the light fill light will be emitted from the display screen itself.
- the light superimposed on the fingerprint recognition area can increase the brightness of the fingerprint recognition area. Therefore, during the recognition process, the light projected by the fingerprint recognition area can be more obviously reflected by the skin of the finger, and then be sensed by the optical fingerprint module. Avoiding the problem that the brightness of the fingerprint identification area is small and the environment with high brightness is greatly affected, and ultimately the speed of fingerprint identification can be improved.

随着人们信息安全保护意识的不断提高, 指纹识别技术已经广泛地应用 在终端设备上。 其中, 光学指纹识别技术以其优良的识别性能, 尤其受到制 造商的青睞, 因此越来越多的终端设备配置有光学指纹模组。
相关技术中, 用户对终端设备的屏占比要求较高, 为了增大终端设备的 屏占比, 屏下指纹识别技术较多地出现在终端设备上, 即将光学指纹模组安 装在显示屏的下方, 当然此种设计需要显示屏具备良好的光透过率。
请参考图 1, 显示屏 101 发出的光线经过光学胶层 102后透过透光盖板 103射出, 由于皮肤 104与空气的光学折射率的差异, 在皮肤 104与透光盖 板 103之间的反射率较小, 而空气与透光盖板 103之间的界面反射率较大, 上述存在反射率差异的光线能够被光学指纹模组 105获取, 进行形成指纹图 像。
但是在实际的使用过程中, 显示屏 101 的亮度不足, 特别是在亮度较高 的环境中, 经过手指的皮肤 104反射到光学指纹模组 105的光线较弱而影响 指纹识别性能, 导致光学指纹模组 105的识别速度较慢, 甚至无法识别。 发明内容

本公开采用的技术方案能够达到以下有益效果:
本公开实施例公开的终端设备通过增加透光补光装置, 并使得透光补光 装置与指纹识别区域相对设置, 因此能够向指纹识别区域投射补光光线, 补 光光线会与显示屏本身发出的光线叠加,从而能够增大指纹识别区域的亮度, 因此在识别的过程中, 指纹识别区域投射出的光线能够较为明显地在被手指 的皮肤反射后, 再被光学指纹模组感应, 进而能够避免由于指纹识别区域的 亮度较小而受亮度较高环境影响较大的问题, 最终能够提高指纹识别的速度。 附图说明

以下结合附图, 详细说明本公开各个实施例公开的技术方案。
请参考图 2 -图 3, 本公开实施例公开一种终端设备, 所公开的终端设备 包括显示屏 100、 透光补光装置 200和光学指纹模组 300。
本公开实施例中, 终端设备包括壳体和显示模组, 显示模组安装在壳体 上。 具体的, 显示模组可以包括透光盖板和显示屏 100, 透光盖板可以通过光 学胶层粘接固定在显示屏 100上, 从而实现对显示屏 100的覆盖防护。 本公 开实施例中, 显示屏 100包括指纹识别区域 110, 指纹识别区域 110指的是能 够供用户手指放置,并能够使得手指的指纹被光学指纹模组 300识别的区域。
为了方便操作, 可选的方案中, 指纹识别区域 110通常可以位于显示屏 100靠近其边緣的部位上。 例如, 指纹识别区域 110可以位于显示屏 100的 底端。 当然, 本公开实施例不限制指纹识别区域 110的具体位置。
显示屏 100设置在光学指纹模组 300上, 即光学指纹模组 300位于显示 屏 100覆盖的空间中。 光学指纹模组 300与指纹识别区域 110相对设置, 此 处的相对设置, 指的是用户的手指放置在指纹识别区域 110上就能够被光学 指纹模组 300感应的位置关系。 光学指纹模组 300的工作过程和工作原理均 为相关技术, 在此不再赞述。
透光补光装置 200 能够起到补光的作用。 本公开实施例中, 透光补光装 置 200与指纹识别区域 110相对设置, 进而能向指纹识别区域 110投射补光 光线。 透光补光装置 200能够透光, 进而不影响光线被手指反射后被光学指 纹模组 300的识别。 在指纹识别的过程中, 透光补光装置 200发出的补光光 线和显示屏 100本身发出的光线叠加, 从而能够使得指纹识别区域 110的亮 度较高,进而能够较为明显地被用户的手指皮肤反射后再被光学指纹模组 300
识别。
本公开实施例公开的终端设备通过增加透光补光装置 200, 并使得透光 补光装置 200 与指纹识别区域 110相对设置, 因此能够向指纹识别区域 110 投射补光光线, 补光光线会与显示屏 100本身发出的光线叠加, 从而能够增 大指纹识别区域 110的亮度, 因此在识别的过程中, 指纹识别区域 110投射 出的光线能够较为明显地在被手指的皮肤反射后, 再被光学指纹模组 300感 应, 能够避免由于指纹识别区域 110 的亮度较小而受亮度较高环境影响较大 的问题, 最终能够提高指纹识别的速度。
更为可选的方案中, 透光补光装置 200的亮度可以大于显示屏 100的亮 度, 此种情况下, 即便在显示屏 100处于未亮屏状态, 单单透光补光装置 200 发出的补光光线仍然会比单独显示屏 100 本身的亮度高, 仍然能够提高指纹 识别速度。 当然, 在显示屏 100处于亮屏状态, 更能够进一步提高指纹识别 速度。
本公开实施例中, 透光补光装置 200与指纹识别区域 110相对设置, 进 而能够向指纹识别区域 110投射补光光线, 终端设备内只要能够达到上述要 求的位置均可以用来安装透光补光装置 200。 例如, 透光补光装置 200 可以 设置在显示屏 100与光学指纹模组 300之间。
本公开实施例中, 显示屏 100可以包括上玻璃层 120、 下玻璃层 130 以 及依次设置在上玻璃层 120与下玻璃层 130之间的阴极层 140、 第一发光层 150和阳极层 160。 阴极层 140、 阳极层 160与第一发光层 150进而形成供电 回路, 进而确保第一发光层 150能够发光。 通常情况下, 上玻璃层 120朝向 透光盖板的一侧可以设置有偏光片 400。
可选的方案中, 透光补光装置 200可以与阴极层 140、 第一发光层 150和 阳极层 160形成的整体叠置, 也就是说, 透光补光装置 200可以设置在显示 屏 100的内部。例如, 透光补光装置 200可以叠置在阴极层 140、 第一发光层 150和阳极层 160形成的整体朝向上玻璃层 120的一侧; 再例如, 透光补光 装置 200也可以叠置在阴极层 140、 第一发光层 150和阳极层 160形成的整 体朝向下玻璃层 120 的另一侧。 此种设置方式无疑能够将透光补光装置 200 集成在显示屏 100内, 进而能够减小占用空间。
更为可选的方案中, 透光补光装置 200可以设置在阳极层 160与下玻璃 层 130之间, 此种结构不但能够减小占用空间, 而且还能够避免对显示屏 100 显示的影响。
本公开实施例中, 显示屏 100 需要具有良好的透光能力, 能够确保指纹 识别工作的进行。 透光补光装置 200可以采用多种发光设备, 只要能够向指 纹识别区域 110 投射补光光线即可。 请再次参考图 3, 一种具体的实施方式 中, 透光补光装置 200可以为 Micro LED发光层。 具体的, 可以采用半导体 制备工艺在显示屏 100内形成一层 Micro LED发光层。 Micro LED发光层可 以为由纳米级的发光二级光材料制成的发光层, Micro LED 发光层的发光效 率高于显示屏 100的发光效率,相同的发光面积内可实现 10倍左右的亮度提 升, 同时 Micro LED发光层的材料寿命较高, 因此能够更好地解决指纹识别 区域 110的亮度问题, 进而能够使得反射到光学指纹模组 300的光强增大, 从而进一步提高光学指纹模组 300的识别速度。
具体的, 透光补光装置 200可以包括第二发光层 210和电极层 220, 第 二发光层 210和电极层 220可以依次设置在阳极层 160与下玻璃层 130之间。 电极层 220与第二发光层 210电连接, 进而能够为第二发光层 210供电, 当 然, 电极层 220需要与终端设备的供电侧电连接。
为了避免透光补光装置 200与显示屏 100之间发生短路, 更可选的方案 中, 透光补光装置 200还可以包括透光绝緣层 230, 透光绝緣层 230可以设 置在第二发光层 210与阳极层 160之间。 具体的, 透光绝緣层 230可以为二 氧化硅层, 进而能够实现更大的透光率。 当然, 透光绝緣层 230还可以采用 其它能够透光的绝緣材料制成, 本公开实施例不限制透光绝緣层 230的具体 材质。
由于透光补光装置 200可以透光, 而显示屏 100也具备良好的透光性, 因此第二发光层 210受第一发光层 150的影响以及光学指纹模组 300受第二 发光层 210的影响均比较小, 此种情况下, 第二发光层 210可以在与指纹识 别区域 110相对的区域内铺设较大的面积, 有利于进一步提高指纹识别区域 110的亮度。
本公开实施例中, 第一发光层 150可以包括呈阵列分布、 且分散设置的
第一发光单元, 例如红色发光单元 151、 绿色发光单元 152和蓝色发光单元 153。 第二发光层 210可以包括呈阵列分布、 且分散设置的第二发光单元, 例 如红色发光单元 211、 绿色发光单元 212和蓝色发光单元 213。
具体的, 第二发光单元与第一发光单元可以错位分布, 也就是说, 第二 发光单元与相邻的两个第一发光单元之间形成的空间相对设置,此种情况下, 第二发光单元不会受第一发光单元的遮挡, 进而能够使得补光光线的透过性 更好, 达到更高的补光亮度。 上述红色发光单元、 绿色发光单元和蓝色发光 单元无疑能够使得第一发光层 150或第二发光层 210具备更优的调色能力, 能够发出多种颜色的光线。
如上文所述, 第一发光层 150和第二发光层 210的相互影响较小, 应该 更多考虑对指纹识别的影响, 基于此, 更为可选的方案中, 相邻的两个第一 发光单元和相邻的两个第二发光单元之间均可以形成透光孔, 透光孔的设置 更有利于反射光线的通过, 能够进一步提高指纹识别的速度。
为了进一步提高透光性, 可选的方案中, 电极层 220 可以为氧化铟锡 (Indium tin oxide, ITO) 走线层。 当然, 电极层 220还可以为其它透明材料 制成的电极层 220。 本公开实施例不限制电极层 220的具体种类。
本公开实施例公开的终端设备还可以包括控制器, 控制器与显示屏 100 和透光补光装置 200相连, 控制器用于控制显示屏 100和透光补光装置 200 切换点亮。 具体的操控过程可以如下: 当显示屏 100处于工作状态时, 显示 屏 100通常处于亮屏状态, 控制器可以控制透光补光装置 200不点亮; 当进 行指纹识别时, 显示屏 100通常处于未亮屏的状态, 此时需要指纹解锁, 控 制器可以控制透光补光装置 200点亮。 上述方案能避免透光补光装置 200 出 现不必要的开启, 进而能够降低终端设备的能耗。
本公开实施例中, 控制器可以为终端设备的中央处理器, 也可以为单独 的控制模块或控制软件。 本公开实施例公开的终端设备中, 显示屏 100可以 为有源矩阵有机发光二极体 ( Active-matrix organic light-emitting diode, AMOLED) 屏, 还可以为其它透光性良好、 而且适合设计屏下指纹识别功能 的显示屏, 本公开实施例不限制显示屏 100的具体种类。
本公开实施例公开的终端设备可以是手机、 平板电脑、 电子书阅读器、
游戏机、 可穿戴设备(例如智能手表)等终端设备, 本公开实施例不限制终端 设备的具体种类。
本公开上文实施例中重点描述的是各个实施例之间的不同, 各个实施例 之间不同的优化特征只要不矛盾, 均可以组合形成更优的实施例, 考虑到行 文简洁, 在此则不再赘述。
以上所述仅为本公开的实施例而已, 并不用于限制本公开。 对于本领域 技术人员来说, 本公开可以有各种更改和变化。 凡在本公开的精神和原理之 内所作的任何修改、 等同替换、 改进等, 均应包含在本公开的权利要求范围 之内。
