Description

显示装置
技术领域
本发明涉及一种显示装置。
背景技术
随着网络技术的发展和社会的进步,电脑已日渐深入人们日常工作、生活和学习等各领域。人们使用电脑来进行文字编辑、购买和出售股票、上网了解各种信息等。电脑通常包括一显示器、主机和键盘,显示器用于给用户提供一个显示界面,以显示文字和图像等信息。主机为一中央处理设备,用于接收键盘输入信息并在处理该输入信息后将信息传递到显示器上,通过显示器将信息展示给用户。
现有的显示器包括阴极射线管显示器(Cathode Ray Tube,CRT)、液晶显示器(Liquid Crystal Display,LCD)、等离子显示器(Plasma Display Panel,PDP)等。然而,上述显示器在未使用时,其显示屏均裸露在外,很容易被外界的硬物划伤其表面,从而对显示屏造成一定程度的损坏,降低其显示效果。
发明内容
有鉴于此,有必要提供一种可保护显示屏的显示装置。
一种显示装置,包括壳体、收容于壳体中的显示屏及屏幕保护装置。壳体上位于所述显示屏顶部设置有收容部,收容部上开设有开口。屏幕保护装置包括动力传动机构及保护幕,动力传动机构设置于收容部中,保护幕穿过开口固定于动力传动机构上。保护幕用于在所述动力传动机构的驱动下卷绕于动力传动机构上或从动力传动机构上展开以遮盖所述显示屏。
一种显示装置,包括壳体、收容于壳体中的显示屏及固定于壳体上的屏幕保护装置。壳体具有收容部。屏幕保护装置包括动力传动机构及保护幕,动力传动机构设置于收容部中,保护幕固定于动力传动机构上。保护幕在动力传动机构的驱动下卷绕于所述动力传动机构上或从动力传动机构上展开以遮盖所述显示屏。
上述显示装置,通过在其壳体内设置屏幕保护装置,保护幕可展开以遮盖显示屏。如此,可防止显示屏被硬物刮伤。
附图说明
图1为一较佳实施方式的显示装置的结构示意图。
图2为图1所示显示装置的使用状态图。
图3为图1中显示装置的功能模块图。
具体实施方式
请参阅图1及图2,一较佳实施方式的显示装置100包括壳体10、用于支撑该壳体10的底座20、收容于壳体10中的显示屏12以及屏幕保护装置30。
壳体10远离底座20的上边缘102具有一水平的收容部120。收容部120上水平开设有一长条形的凹槽122,收容部120形成凹槽122的结构上开设有一长条形的开口124。凹槽122的宽度大于开口124的宽度。
屏幕保护装置30包括动力传动机构302、止挡件304、以及保护幕306。动力传动机构302设置于收容部120中,其包括驱动轴312及马达314。马达314固定于收容部120内。驱动轴312的一端可旋转地安装于收容部120内,另一端与马达314连接在一起。
保护幕306为软性材料制成。保护幕306成方形,其一边缘穿过开口124固定于动力传动机构302的驱动轴312上,与之相对的另一边缘与止挡件304连接在一起。保护幕306在显示装置100的背光开启时卷绕于驱动轴312上,止挡件304收容于凹槽122中。在本实施方式中,止挡件304的尺寸大于开口124的宽度。
请一并参阅图3,显示装置100包括处理单元320、背光模组322及设定单元324。在本实施方式中,显示装置100为液晶显示器。处理单元320用于侦测到背光模组322的背光关闭时,产生第一电信号传送给马达314。马达314根据第一电信号产生动力以带动驱动轴312正向旋转,保护幕306在驱动轴312正向旋转的传动力作用下产生向下推动力。止挡件304在自身重力和保护幕306的向下推动力作用下滑出凹槽122,保护幕306在自身重力和驱动轴312正向旋转的传动力作用下向远离动力传动机构302的方向移动。设定单元324用于接受用户预先设定马达314旋转的时间,所述设定方式可为通过控制显示装置100的遥控器(图未示)或设置于显示装置100上的按键(图未示)设定。处理单元320用于计算马达314正向旋转的时间,并将正向旋转时间与预设时间进行比较。当正向旋转时间与预设时间相等时,处理单元320即控制马达314停止旋转。如此,当马达314停止旋转时,保护幕206展开以遮盖保护显示屏14,如图2所示,可防止显示屏14沾染灰尘或被外界的硬物划伤其表面。
在其他实施方式中,设定单元324还可用于接受用户预先设定马达314旋转的圈数,处理单元320用于计算马达314旋转的圈数,并将旋转圈数与预设圈数进行比较。当旋转圈数与预设圈数相等时,处理单元320即控制马达314停止旋转。
处理单元320还用于侦测到背光模组322的背光开启时,产生第二电信号传送给马达314。马达314根据第二电信号产生动力以带动驱动轴312反向旋转,保护幕306在驱动轴312反向旋转的传动力作用下向靠近动力传动机构302的方向移动,并产生向上牵引力。处理单元320用于计算马达314反向旋转的时间,并将反向旋转时间与预设时间进行比较。当反向旋转时间与预设时间相等时,处理单元320即控制马达314停止旋转。如此,当马达314停止旋转时,保护幕306卷绕于驱动轴312上,止挡件304收容于凹槽122中,如图1所示。由于止挡件304的尺寸大于开口124的宽度,可防止止挡件304在保护幕306的向上牵引力作用下穿过开口124。
本实施方式通过在显示装置100上设置屏幕保护装置30,当显示装置100的背光关闭时,保护幕306可展开遮盖显示屏12。如此,既可防止显示屏14被外界的硬物划伤其表面,又可防止显示屏14沾染灰尘或污物。当显示装置100的背光开启时,保护幕306可回缩卷绕于驱动轴312上,止挡件304收容于凹槽122中。如此,用户可以通过显示屏14观看视频节目及图像等。
本技术领域的普通技术人员应当认识到,以上的实施方式仅是用来说明本发明,而并非用作为对本发明的限定,只要在本发明的实质精神范围之内,对以上实施例所作的适当改变和变化都落在本发明要求保护的范围之内。
