Abstract
示例性实施方式涉及光吸收隐私膜。例如,隐私膜可包括隐私门,当隐私膜与显示面板相邻时,该隐私门至少部分阻挡由显示面板所显示的内容。隐私膜还可包括光吸收材料以吸收来自所述内容的光。
Description
背景技术
计算设备可以包括允许用户查看内容的显示设备和/或可以与允许用户查看内容的显示设备通信。一些显示设备可为允许用户提供触摸输入的触摸屏显示设备。例如,用户可以用他们的手指和/或手写笔在屏幕上提供触摸输入从而操控屏幕上的内容。
附图说明
结合下述附图,描述了本申请的一些实施例:
图1为用于提供隐私和吸收光的示例性隐私膜的方块图;
图2为示例性显示设备的方块图,该显示设备包括用于提供隐私和吸收光的隐私膜;和
图3为示例性显示设备的方块图,该显示设备包括用于提供隐私和吸收光的永久隐私膜。
具体实施方式
如上所述,计算设备可以包括允许用户查看内容的显示设备和/或可以与允许用户查看内容的显示设备通信。这些设备的例子包括智能手机、平板电脑、笔记本电脑、监控器等。由于这些设备的使用已经很普遍,因此在使用这些设备的同时保护用户的隐私已成为人们关注的问题。此外,长期使用这些显示设备可能给用户带来健康问题,比如用户的眼睛不适、眼睛损伤和/或疾病、眼睛过早老化等。
本文所讨论的实施例提供了通过使用光吸收隐私膜提供了紫外线(UV)和/或蓝光吸收的技术。例如,隐私膜可包括隐私门,从而当隐私膜与显示面板相邻时,至少部分阻挡由显示设备的显示面板所显示的内容。隐私膜还可包括光吸收材料,从而吸收可从内容发射的光(例如,UV光和/或蓝光)。在一些实施例中,光吸收材料可包括、包含在隐私膜中的每个隐私门中和/或是隐私膜中的每个隐私门的一部分。在其他实施例中,光吸收材料可以围绕隐私膜中的隐私门。
现在参考附图,图1为提供隐私和吸收光的示例性隐私膜100的方块图。隐私膜100的外部可由任何合适的材料制成。在一些实施例中,隐私膜100的外部可为塑料基板,比如聚丙烯酸酯(polyacrylic)、聚(甲基丙烯酸甲酯)(PMMA)、聚碳酸酯、环烯烃共聚物(COC)、聚对苯二甲酸乙二醇酯(PET)等。
隐私膜100包括任何适当数量的隐私门102。隐私门102可由任何合适的材料制成,当隐私膜100与显示面板相邻时,所述材料能够至少部分阻挡可由显示设备的显示面板所显示的内容。隐私门102可具有任何合适的梯度水平和/或密度(例如,隐私门102的数量)以控制内容被阻挡的程度和/或通过隐私门102所显示的程度。
在一些实施例中,多个隐私门102可以各自相对于隐私膜102的表面以特定角度倾斜,其中特定角度可以决定通过隐私门102显示的内容的量和/或被隐私门102阻挡的内容的量。
隐私膜100还包括区域104,其为围绕隐私门102的区域。区域104可以允许来自显示设备的显示面板的内容通过隐私门102至少部分被显示。
隐私膜100还可包括光吸收材料,以吸收来自显示设备的显示面板所显示的内容的光。光吸收材料可为吸收UV和/或蓝光的任何合适的材料,比如,透明和/或半透明蓝光吸收剂、UV吸收剂等。透明和/或半透明蓝光吸收剂的例子包括铁氧化物、NiTiO3、叶黄素、硫化铬酸铅黄、亚锑酸铅黄、铅-锡-锑黄、二芳基化物(diarylide)、芳基化物、双乙酰乙酰芳基化物、苯并咪唑酮等。UV吸收剂的例子包括苯甲酮、邻氨基苯甲酸盐、二苯甲酰甲烷、PABA衍生物、水杨酸盐、肉桂酸盐、樟脑衍生物(例如,290-400nm)等。UV和/或蓝光吸收的程度可以由光吸收材料的密度控制。在一些实施例中,光吸收材料在每个隐私门102内。在其他实施例中,光吸收材料围绕隐私门102(例如,在区域104内)。
图2为示例性显示设备200的方块图,显示设备200包括用于提供隐私和吸收光的隐私膜202。隐私膜202可与图1的隐私膜100类似。
显示设备200还可包括显示面板208以显示内容。显示面板208可为任何合适类型的显示面板,比如液晶显示器(LCD)、有机发光二极管(OLED)显示器、聚合物发光二极管(PLED)显示器、等离子体显示器、双稳态显示器(例如,胆甾型显示器、胆甾型LCD、基于微电子机械系统(MEMS)的显示器、电子油墨显示器等)等。
图2的隐私膜202可与显示面板208相邻(例如,靠近、接触等),并且可包括任何合适数量的隐私门204(例如,类似于图1的隐私门102)以及光吸收材料。隐私膜202还可包括围绕隐私门204的区域206,类似于图1的区域104。隐私膜202中的光吸收材料可在每个隐私门204内或围绕隐私门204(例如,在区域206中)。
在一些实施例中,隐私膜202可以永久性地粘贴至显示面板208(例如,使用粘合剂)。在其他实施例中,隐私膜202能够从显示面板208上移除。
图3为示例性显示设备300的方块图,显示设备300包括用于提供隐私和吸收光的永久性隐私膜302。隐私膜302与图1的隐私膜100和图2的隐私膜202类似。
显示设备300包括显示面板308,其与图2的显示面板208类似。隐私膜302可与显示面板308相邻,并且可包括任何数量的隐私门304(例如,与图1的隐私门102和图2的隐私门204类似)。隐私膜302还可包括光吸收材料,该光吸收材料可在每个隐私门304内或在区域306内,区域306为围绕隐私门304的区域(例如,与图1的区域104和图2的区域206类似)。在一些实施例中,隐私门302还可包括硬涂层310,其可为任何合适的硬涂层以保护隐私膜302。
在图3的实施例中,隐私膜302可以使用任何合适的粘合剂永久性地粘贴至显示面板308,比如光学透明粘合剂(OCA)312和/或光学透明树脂(OCR)(例如,聚丙烯酸酯、PMMA、聚碳酸酯、COC、PET等)。
隐私膜302还可包括塑料离型膜314,塑料离型膜314可用于防止隐私膜302粘附至显示面板308。塑料离型膜314可由任何合适的材料(例如,PET)制成,并且当准备将隐私膜302永久性地粘附至显示面板308时,能够移除塑料离型膜314。
