具体实施方式
本发明提供了一种高对比度透明显示设备及其控制方法，为使本发明的目的、技术方案及效果更加清楚、明确，以下对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供了一种高对比度的透明显示设备，其中，如图9所示，所述透明显示设备包括一透明LED显示屏100，设置在所述透明LED显示屏100背光侧的薄膜晶体管液晶显示屏200，以及用于控制所述透明LED显示屏100以及薄膜晶体管液晶显示屏200的控制器300；所述控制器300与所述透明LED显示屏100以及薄膜晶体管液晶显示屏200分别电连接，所述控制器300用于控制所述薄膜晶体管液晶显示屏200关闭以阻止环境光射入所述透明LED显示屏100，从而实现透明LED显示屏100的高对比度显示。
具体来讲，在本发明中，所述薄膜晶体管液晶显示屏(TFT-LCD)与所述透明LED显示屏平行设置，且所述薄膜晶体管液晶显示屏设置在所述透明LED显示屏的背光侧，通过所述控制器可对薄膜晶体管液晶显示屏发送关闭信号，所述薄膜晶体管液晶显示屏接收到关闭信号后，能够对环境中的光进行阻挡，从而避免环境光进入到透明LED显示屏的显示区域。
也就是说，所述薄膜晶体管液晶显示屏在关闭状态的时候对光的透过率极小，约为0.001％左右，能够起到非常好的光阀的作用，薄膜晶体管液晶显示屏后方的环境光不能进入到透明LED显示屏的显示区域，即可有效提升本发明透明显示设备的对比度。
作为其中一实施方式，所述薄膜晶体管液晶显示屏包括薄膜晶体管基板、滤光片基板以及设置在所述薄膜晶体管基板和滤光片基板之间的液晶材料，所述滤光片基板包括玻璃基片及设置在玻璃基片上的无颜色光阻的滤光层。具体来讲，常用的薄膜晶体管液晶显示屏中通常采用的是具有红绿蓝颜色光阻的滤光层，而本发明为了降低混色、漏光等风险，采用了无颜色光阻的滤光层，如图10所示；也就是说，本发明所采用的薄膜晶体管液晶显示屏仅能够显示黑白灰阶，不能显示彩色，这在一定程度上也提升了透明显示设备的对比度。
优选地，在本实施方式的薄膜晶体管液晶显示屏中，在所述无颜色光阻的滤光层之间还设置有黑色矩阵材料，所述黑色矩阵材料沉积在所述玻璃基片上，以防止漏光，所述黑色矩阵材料可以是有机材料，也可以是无机材料。
进一步地，通过在所述玻璃基片上沉积黑色矩阵材料以及采用无颜色光阻滤光层，使得本发明中的TFT-LCD开口率较大，透过率也更高。
更优选地，本发明还可根据需求对透明显示设备的透明度以及对比度进行选择平衡，若本发明要求更高的透明度，则可牺牲掉一定的对比度，不使用黑色矩阵材料。
作为其中一实施方式，所述透明LED显示屏包括透明基板、均匀设置在所述透明基板上的若干LED元件以及用于对所述LED元件进行封装的透明封装结构。
优选地，所述透明LED显示屏还包括与所述LED元件一一对应设置的匀光元件，所述匀光元件用于将LED元件发出的亮度不均匀的光处理为亮度均匀的光。
进一步地，如图11所示，所述单个LED元件对应薄膜晶体管液晶显示屏中多个像素点。例如，所述单个LED元件可对应薄膜晶体管液晶显示屏中4个、6个、8个、10个或12个等多个像素点，但不限于此。所述薄膜晶体管液晶显示屏中的每个像素点均由单个开关分别单独控制，通过控制像素点关闭的数量，能够对所述透明显示设备的对比度进行调控。
在一具体实施方式中，若单个LED元件对应薄膜晶体管液晶显示屏中8个像素点，在所述LED元件开启时，若8个像素点均为关闭状态，此时该LED元件所对应的显示区域对比度最高；若8个像素点中只有4个为关闭状态，此时显示屏后方的环境光部分会透射到LED显示屏的显示区域，此时该LED元件所对应的显示区域对比度较低。
基于上述高对比度透明显示设备，本发明还提供一种高对比度透明显示设备的控制方法，其中，如图12所示，包括步骤：
S10、通过控制器向所述透明LED显示屏发送开启信号，使所述透明LED显示屏中的LED元件发光；
S20、通过控制器向所述薄膜晶体管液晶显示屏发送关闭信号，使所述发光的LED元件对应的薄膜晶体管液晶显示屏中的若干像素点选择性关闭，实现对透明显示设备的对比度进行控制。
具体来讲，在本发明高对比度透明显示设备中，所述薄膜晶体管液晶显示屏 设置在所述透明LED显示屏的背光侧，所述薄膜晶体管液晶显示屏用于对其后方的环境光进行管控，避免环境光透射到透明LED显示屏的显示区域，从而提升透明显示设备的对比度。
作为其中一实施方式，薄膜晶体管液晶显示屏具有多种驱动模式，本实施方式以常黑薄膜晶体管液晶显示屏为例，通过控制器向所述透明LED显示屏发送开启信号，使所述透明LED显示屏中的LED元件发光；然后通过控制器向所述薄膜晶体管液晶显示屏发送关闭信号，使所述发光的LED元件对应的薄膜晶体管液晶显示屏中的若干像素点选择性关闭，所述薄膜晶体管液晶显示屏在像素点处于关闭状态时对光的透过率极小，能够起到光阀作用，这样薄膜晶体管液晶显示屏后方的环境光就不能够透射到透明LED显示屏的显示区域，从而提高透明显示设备的对比度。进一步地，若透明LED显示屏非显示图像像素下方对应的薄膜晶体管液晶显示屏像素均为打开状态，则此非显示图像区域为透明状态。
有益效果：本发明提供的一种高对比度透明显示设备及其控制方法，所述高对比度透明显示设备包括一透明LED显示屏，设置在所述透明LED显示屏背光侧的薄膜晶体管液晶显示屏，以及用于控制所述透明LED显示屏以及薄膜晶体管液晶显示屏的控制器，通过控制器控制所述薄膜晶体管液晶显示屏关闭以阻止环境光射入所述透明LED显示屏，从而实现透明LED显示屏的高对比度显示。本发明提供的透明显示设备在保持透明的基础上还能极大提升对比度，对比度是显示效果中非常重要的因素，高对比度的显示设备比低对比度显示设备具有更佳的视觉效果，本发明可使透明显示成像效果得到极大提升。
应当理解的是，本发明的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本发明所附权利要求的保护范围。
