本申请要求享有于2014年8月14日提交的名称为“无边框显示器”的中国专利申请CN201410399879.1的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本发明涉及液晶显示领域，特别涉及液晶显示器。
背景技术
目前，市售的电视或者显示器主要有以下几种类型：CRT(阴极射线管)电视或显示器、液晶电视或显示器，OLED(有机发光二极管)电视或显示器。
随着客户对美观的追求，超窄边框的液晶电视或显示器已经是大势所趋。CRT电视或显示器中需要很宽的边框进行显像管的固定，所以CRT电视或显示器的边框非常宽。随着液晶显示技术不断完善，液晶电视或显示器的边框已经越来越窄。液晶电视或显示器的边框包括治具部分和黑色矩阵。治具部分通常由金属边框构成以起到固定作用，黑色矩阵用来遮挡液晶屏边缘，防止漏光等。目前，业界最窄边框包括5mm宽的治具部分和3mm宽的黑色矩阵。
为了达到最大的较佳的美观性，需要一种无边框显示器。
发明内容
针对上述问题，本发明提出了一种无边框显示器。这种无边框显示器实现了真正的无边框，具有较好的美观性。
根据本发明，提出了一种无边框显示器，包括：显示器主体和设置在显示器主体的显示面之外的透明放大体，透明放大体能够将显示面放大，显示器主体包括围绕显示面的边框，透明放大体包括完全覆盖显示器主体的显示面的接收区和与接收区正对的显示区，透明放大体的显示区大于或等于边框的外沿限定的区域。
根据本发明的无边框显示器，由于透明放大体的显示区大于或等于边框的外沿限定的区域。在使用这种无边框显示器显示画面时，从视觉上来看，完全看不到显示器的边框，从而达到了较好的美观性。
在一个实施例中，透明放大体能将显示面等比放大。在本申请中，用语“等比放大”是指在透明放大体的显示区所显示的画面与显示器主体的显示面所显示的画面内容相同，仅是大小发生了变化。通过使用这种类型的透明放大体，在透明放大体的显示区所显示的画面没有失真，具有良好的显示品质，使用者也完全不会感觉到有透明放大体的存在。
在一个实施例中，透明放大体呈四棱台形，透明放大体的小端为接收区，大端为的显示区，并且接收区平行地朝向显示器主体的显示面。边框凸出到显示面之外，边框的内表面从显示面朝向边框的顶部向外倾斜，内表面的倾斜度与透明放大体的侧壁的倾斜度相同。通过这种结构的透明放大体和边框，来自显示面的光线以某一入射角度从透明放大体的接收区射入到透明放大体中并发生折射，然后从透明放大体的显示区以某一出射角度射出。由于透明放大体的折射率大于空气的折射率，因此该出射角度会大于入射角度，从而增大了出射光的范围，并由此实现在透明放大体的显示区上布满了画面而完全看不到显示器主体的边框，实现无边框显示器效果。这种放大方式所使用的部件很少，简化了显示器的生产并且降低了生产成本。此外，由于这里仅使用了光的折射作用，实质上是光线发生了平移，从而在透明放大体的显示区所显示的画面与显示器主体的显示面所显示的画面内容相同，仅是大小发生了变化，即实现了等比放大。
在一个实施例中，透明放大体对光的折射率在1.5到1.6之间。在一个优选的实施例中，透明放大体为水晶玻璃。透明放大体的轴截面为等腰梯形，梯形的较短的底与腰之间的第一夹角为150度。
在一个优选的实施例中，透明放大体通过其侧壁与边框的内表面的固定连接而与显示器主体固定相连，接收区落入边框的内表面围成的区域内，显示区与边框的顶部齐平或凸出到边框的顶部之外。在一个优选的实施例中，透明放大体的侧壁与边框的内表面之间通过透明粘合剂固定相连。若显示区与边框的顶部齐平，从外观上完全看不出来设置有透明放大体，提高了无边框显示器的美观性。此外，通过控制显示区凸出到边框的顶部之外的距离，能够实现将显示器主体的显示面放大到不同的比例，从而制造成不同尺寸的无边框显示器。在另一个优选 的实施例中，透明放大体的处于边框的内表面围成的区域内的部分的厚度与透明放大体的凸出到边框的顶部之外的部分的厚度之比在1∶1到1∶2之间。这种尺寸的透明放大体能达到适中的放大功能，并且其安装稳定性也较好。
与现有技术相比，本发明的优点在于：(1)本发明的无边框显示器包括显示器主体和设置在显示器主体的显示面之外的透明放大体。由于透明放大体的显示区大于或等于边框的外沿限定的区域，因此从视觉上来看，完全看不到显示器的边框，从而达到了显示器的美观性。(2)透明放大体的材质和形状通过使光线在接收区和显示区这两个界面处发生适当折射，而实现了对显示面等比放大。这种等比放大方式所使用的部件很少，简化了生产并且降低了生产成本。
附图说明
在下文中将基于实施例并参考附图来对本发明进行更详细的描述。其中：
图1显示了根据本发明的无边框显示器的侧视图。
图2是图1中I部分的放大视图。
图3是图1的A向视图。
图4是根据本发明的透明放大体的放大原理图。
在附图中，相同的部件使用相同的附图标记。附图并未按照实际的比例。
具体实施方式
下面将结合附图对本发明作进一步说明。
图1示意性地显示了根据本发明的无边框显示器100结构。如图1所示，无边框显示器100包括显示器主体10和设置在显示器主体10之外的透明放大体30。显示器主体10包括显示面13和围绕在显示面13的边框14，透明放大体30具有放大作用，并且透明放大体30的接收区31完全覆盖了显示面13，而透明放大体30的显示区32大于或等于边框14的外沿限定的区域，即透明放大体30的显示区32完全覆盖了边框14，在图1中示意性地显示了显示区32大于边框14的外沿限定的区域。这样，从无边框显示器100的正面，即图1中A向看去(如图3所示)，完全看到不到边框14，在视觉上实现了无边框显示器，使得无边框显示器100具有较好的美观性。
如图2所示，边框14凸出到显示器主体10的显示面13之外，并且边框14 的内表面15从显示面13朝向顶部16向外倾斜。如果没有设置透明放大体30，则边框14会显示出来而使得显示器主体10不具有美观性。
为了将透明放大体30安装到边框14上，并且使透明放大体30具有等比放大的效果以避免画面变形失真，可将透明放大体30制造为四棱台形，其轴截面为等腰梯形，如图4所示。透明放大体30的小端为接收区31、大端为显示区32并且透明放大体30的侧壁的倾斜度与边框14的内表面15的倾斜度相同。在安装状态中，透明放大体30的小端平行地朝向显示器主体10的显示面。如图4所示，从显示器主体10的显示面13射出的光线50从透明放大体30的接收区31射入到透明放大体30内，然后从透明放大体30的显示区32射出。光线在接收区31和显示区32两个界面处发生折射，由于透明放大体30的折射率大于空气的折射率，因此该出射角度会大于入射角度，从而增大了出射光的范围，并由此实现在透明放大体的显示区上布满了画面而完全看不到显示器主体的边框，实现无边框显示器效果。此外，由于这里仅使用了光的折射作用，实质上是光线发生了平移，从而在透明放大体30的显示区所显示的画面与显示器主体的显示面所显示的画面内容相同，仅是大小发生了变化，即实现了等比放大。这种等比放大方式所使用的主要部件仅透明放大体30，从而简化了无边框显示器100的生产并且降低了生产成本。在一个实施例中，透明放大体30的侧壁与边框14的内表面15之间通过透明粘合剂固定相连。
透明放大体30可选择对光的折射率在1.5到1.6之间的材料。在一个具体的实施例中，透明放大体30为水晶玻璃，其折射率为1.52。在这种情况下，从透明放大体30的等腰梯形的轴截面来看，透明放大体30可构造为：梯形的较短的底与腰之间的第一夹角α1为150度，梯形的较长的底与腰之间的夹角为30度。在这种实施例中，边框14的内表面15与显示器主体10的显示面13形成的夹角为150度。这样，通过使用这种形状的透明放大体30，来自显示器10的显示面13的所有的光会射入到透明放大体30内并经折射后从显示区32射出，提高了无边框显示器100的显示品质。
此外，还将透明放大体30构造为：透明放大体30处于边框14的内表面15围成的区域内的部分的厚度D1与透明放大体30的凸出到边框14的顶部之外的部分的厚度D2之比在1∶1到1∶2之间。这种尺寸的透明放大体30能达到适中的放大功能，并且其安装稳定性也较好。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
