本公开使用的所有术语(包括技术术语或者科学术语)与本公开所属领域的普通技术人员理解的含义相同,除非另外特别定义。还应当理解,在诸如通用字典中定义的术语应当被解释为具有与它们在相关技术的上下文中的含义相一致的含义,而不应用理想化或极度形式化的意义来解释,除非这里明确地这样定义。

发明人经过研究发现,在相关技术中,光学传感器与显示面板直接接触。在用户在进行触控操作的情况下,在显示面板与光学传感器直接接触的接触面上会形成压痕。所形成的压痕会影响显示面板的性能。
为此,本公开提出一种有效避免在显示面板表面产生压痕的方案。
图1是根据本公开一个实施例的显示模组的结构示意图。
如图1所示,显示模组包括显示面板1、光学传感器2和散热层3。光学传感器2设置在显示面板1的出光侧的对侧,散热层3设置在显示面板1和光学传感器2之间。散热层3上设有通孔阵列,光线通过通孔阵列中的通孔31到达光学传感器2中的光学识别器件21。
在一些实施例中,散热层3的面积可与显示面板1的面积相同。在另一些实施例中,散热层3的面积可小于显示面板1的面积。
在一些实施例中,散热层3的面积可与光学传感器2的面积相同,以确保通过散热层3中的通孔31的光线被光学传感器2中的光学识别器件21有效接收。
在一些实施例中,显示面板1可为柔性显示面板,或者其它类型的显示面板。由于光学传感器并不会与显示面板直接接触,因此有效避免在显示面板的表面上形成压痕,保证显示面板稳定工作。
在一些实施例中,散热层3的材料包括金属材料。通过采用金属材料,可有效进行散热。例如,散热层3可采用铜、铝等金属材料,或者适当的合金材料。在一些实 施例中,散热层3可采用铜箔制成。
在本公开上述实施例提供的显示模组中,通过将散热层设置在显示面板和光学传感器之间,散热层上设有通孔阵列以实现小孔成像。从而光学传感器无需与显示面板直接接触,有效避免了在显示面板的表面上形成压痕。此外,散热层还能将显示面板和光学传感器在工作时所产生的热能及时散掉,以确保显示面板和光学传感器稳定工作。
图2是根据本公开另一个实施例的显示模组的结构示意图。图2与图1的不同之处在于,在图2所示实施例中,光学传感器2还包括透镜阵列,以便对通过通孔31的光线进行汇聚。
如图2所示,透镜阵列中的每个透镜22设置在光学识别器件2的靠近散热层3的一侧,并且与通孔阵列中的通孔31一一对应。即,通孔阵列中的每个通孔与透镜阵列中唯一的一个透镜相对应,透镜阵列中的每个透镜也与通孔阵列中唯一的一个通孔相对应。
在一些实施例中,透镜22的光轴穿过对应通孔31。通过上述设置,可使通过通孔31的光线尽可能多地到达对应的透镜22。在另一些实施例中,透镜22的光轴与对应通孔31的中心轴重合。
图3是根据本公开又一个实施例的显示模组的结构示意图。
如图3所示,用户将手指4按压在显示面板1的表面,相应的光线通过通孔31后,通过对应透镜22到达光学识别器件21。光学传感器2通过汇总各光学识别器件所形成的指纹图像,以获得用户手指4的指纹信息。
由于光学传感器能够识别指纹,因此用户通过触摸显示面板,就可实现指纹识别。
图4是根据本公开一些实施例的散热层的结构示意图。
如图4所示,散热层3上设有通孔阵列。在一些实施例中,为了确保光线能够穿过通孔31,并且还能避免外界干扰,通孔31的孔径为6μm~12μm。例如,通孔31的孔径可设为6.5μm。
在一些实施例中,通孔31的形状可为圆形、方形或其它有利于形成小孔成像的形状。
本公开实施例还提供了一种显示装置,其包括上述任一种显示模组。该显示装置可以为:LCD(Liquid Crystal Display,液晶显示器)、LED(Light Emitting Diode,发光二极管)显示器、OLED(Organic Light Emitting Diode,有机发光二极管)显 示器、手机、平板电脑、电视机、显示器、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。
在上述显示装置中,由于光学传感器不与显示面板直接接触,有效避免了在显示面板的表面上形成压痕。此外,散热层还能将显示面板和光学传感器在工作时所产生的热能及时散掉,以确保显示面板和光学传感器稳定工作。
图5是根据本公开一个实施例的显示模组制备方法的流程示意图。
在步骤501,在显示面板的出光侧设置散热层。
在一些实施例中,显示面板为柔性显示面板。
在一些实施例中,通过对散热材料层进行图案化,以得到具有通孔阵列的散热层。
在一些实施例中,散热层的材料包括金属材料,因此可有效进行散热。例如,散热层可采用铜、铝等金属材料,或者适当的合金材料。在一些实施例中,散热层可采用铜箔制成。
在一些实施例中,为了确保光线能够穿过通孔阵列中的通孔,并且还能避免外界干扰,通孔阵列中的通孔孔径为6μm~12μm。例如,通孔的孔径可设为6.5μm。
在一些实施例中,通孔阵列中的通孔的形状可为圆形、方形或其它有利于形成小孔成像的形状。
在步骤502,在散热层的远离显示面板的一侧设置光学传感器。
由于散热层上设有通孔阵列,因此光线能够通过通孔阵列中的通孔到达光学传感器中的光学识别器件。
在一些实施例中,光学传感器被配置为识别指纹。由此,用户通过触摸显示面板,就可实现指纹识别。
在一些实施例中,在光学识别器件的靠近散热层的一侧设置透镜阵列。透镜阵列中的透镜与通孔阵列中的通孔一一对应。在一些实施例中,透镜的光轴穿过对应通孔。通过上述设置,可使通过通孔的光线尽可能多地到达对应的透镜。例如,透镜的光轴与对应通孔的中心轴重合。
在本公开上述实施例提供的显示模组制备方法中,通过将散热层设置在显示面板和光学传感器之间,散热层上设有通孔阵列以实现小孔成像。从而光学传感器无需与显示面板直接接触,有效避免了在显示面板的表面上形成压痕。此外,散热层还能将显示面板和光学传感器在工作时所产生的热能及时散掉,以确保显示面板和光学传感器稳定工作。
在一些实施例中,通过将显示面板、散热层和光学传感器进行压合,从而得到显示模组成品。
图6是根据本公开一个实施例的显示模组成品的结构示意图。
如图6所示,显示模组包括显示面板1、光学传感器2和散热层3。散热层3设置在显示面板1的出光侧,光学传感器2设置在散热层3的远离显示面板1的一侧。散热层3上设有通孔阵列,光线通过通孔阵列中的通孔31到达光学传感器2中的光学识别器件21。
至此,已经详细描述了本公开的实施例。为了避免遮蔽本公开的构思,没有描述本领域所公知的一些细节。本领域技术人员根据上面的描述,完全可以明白如何实施这里公开的技术方案。
虽然已经通过示例对本公开的一些特定实施例进行了详细说明,但是本领域的技术人员应该理解,以上示例仅是为了进行说明,而不是为了限制本公开的范围。本领域的技术人员应该理解,可在不脱离本公开的范围和精神的情况下,对以上实施例进行修改或者对部分技术特征进行等同替换。本公开的范围由所附权利要求来限定。
