 本发明的最佳实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。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。
本发明涉及一种LCD和LED混合显示屏，包括：LCD显示屏、重叠设置在所述LCD显示屏后侧的LED显示屏，以及用于驱动所述LCD显示屏和所述LED显示屏的驱动装置，所述LED显示屏上设置至少一个LED图案，每个LED图案包括多个笔画，每个笔画对应至少一个LED灯；所述驱动装置用于驱动所述LCD显示屏显示至少一个LCD显示图案和驱动所述LED灯发光，所述LED灯发光形成的LED显示图案和所述LCD显示图案一一对应。在此，一一对应的意思可以是一个位于一个之上，并且彼此重叠或者彼此不重叠。在此，需要说明的是，彼此重叠可以是指大小相同完全重叠，也可以指大小近似，且一者位于另一者之上因此部分重叠。实施本发明的LCD和LED混合显示屏，通过将LCD显示屏和LED显示屏重叠设置，能够兼顾不同环境亮度并且降低功耗。
图1是本发明的LCD和LED混合显示屏的第一优选实施例的组合示意图。如图1所示，所述LCD和LED混合显示屏包括：LCD显示屏100、重叠设置在所述LCD显示屏100后侧的LED显示屏200，以及用于驱动所述LCD显示屏100和所述LED显示屏200的驱动装置300。所述LED显示屏200上设置至少一个LED图案210，每个LED图案210包括多个笔画211，每个笔画211对应至少一个LED灯（参见图2）。所述LCD显示屏100在受到所述驱动装置300驱动通电时会显示至少一个LCD显示图案110。所述LED显示屏200在受到所述驱动装置300驱动时，对应的LED灯会发光，从而形成LED显示图案220。如图1所示，所述LED灯发光形成的LED显示图案220和所述LCD显示图案110一一对应并且彼此重叠，这样LCD显示图案110和LED显示图案220同时组成所述LCD和LED混合显示屏的显示图案。这样通过将LCD显示屏和LED显示屏重叠设置，能够兼顾不同环境亮度并且降低功耗。
优选的，所述LCD显示屏100和 LED显示屏200的尺寸完全相同，并且LCD显示图案110和LED显示图案220也完全相同。当然，在本发明的其他优选实施例中，所述LCD显示屏100和 LED显示屏200的尺寸可以有所不同，并且LCD显示图案110和LED显示图案220也可以有所不同。所述LCD显示屏100和 LED显示屏200可以是由一个LCD显示屏100和一个LED显示屏200重叠构成的一体结构也可以是由两块单独的 LCD显示屏100 LED显示屏200彼此重叠装配形成。
在本发明的优选实施例中，所述LED显示图案210和所述LCD显示图案110为显示数字，例如时间显示数字，温度显示数字等等。在本发明的其他优选实施例中，所述LED显示图案210和所述LCD显示图案110还可以是其他显示内容，比如花瓣，动物图像等等。
在本发明的优选实施例中，所述LCD显示屏100、所述LED显示屏200以及所述驱动模块300可以采用本领域中已知的LCD显示屏，LED显示屏，以及LCD/LED驱动电路、芯片构造。本领域技术人员可以采用任何已知的LCD显示屏、LED显示屏200以及LCD/LED驱动电路或芯片来实现本发明。
图2是图1所示的LCD和LED混合显示屏的LED显示屏的优选实施例的结构示意图。如图2所示，所述LED显示屏200包括PCB板230，设置在所述PCB板230上的多个LED灯240。所述LED图案220为透光结构，例如其每个笔画221由一组透光孔222组成。当然每个笔画221还可以由一个或一组透光缝隙组成，每个缝隙可以对应一个或者多个LED灯240。所述LED显示屏200上设置散射膜270，所述散射膜优选是白色或者浅色，其同时也可以用作LCD显示屏的反射膜。所述散射膜270的大小优选与LED显示屏200的大小相同，也可以不同。
如图2所示，所述LED图案220可以是时间显示数字，其包括至少四个8形时间显示数字，每个8形时间显示数字包括7个笔画211，每个笔画211包括至少一组透光孔222。在发明的一个简化实施例中，其中至少一个所述LED灯240发出光透过所述至少一组透光孔222透射出来。在发明的优选实施例中，每一组透光孔222下都至少设有一个LED灯240以使得所述LED灯240发出的光从所述每一组透光孔222中透射出来。如图所示，每个8形时间显示数字由三横四竖7个笔画211组成，其中每一横包括3个透光孔，每一竖包括4个透光孔，其中每个透光孔22间的距离相等。对应的，所述LCD显示图案110可以与所述LED灯发光形成的LED显示图案220一一对应并且彼此重叠而且大小相同，这样就可以同时LCD显示图案110和LED显示图案220同时组成所述LCD和LED混合显示屏的显示图案。
在本发明的另一优选实施例中，采用12时计时，也就是说，从1点到12点计时。在该实施例中，表示小时的十位只用显示0和1。因此在该实施例中，所述LED图案220包括三个8形时间显示数字和一个1形时间显示数字，其中每个8形时间显示数字包括7个笔画211，每个笔画211包括至少一组透光孔222。该1形时间显示数字可包括一个较长的笔画211或是两个较短的笔画211，每个笔画211包括至少一组透光孔222。在本发明的再一优选实施例中，采用24时计时，也就是说，从0点到24点计时。在该实施例中，表示小时的十位只用显示0、1和2。因此在该实施例中，所述LED图案220设有三个8形时间显示数字和一个己形时间显示数字。其中每个8形时间显示数字包括7个笔画211，每个笔画211包括至少一组透光孔222，每个己形时间显示数字包括6个笔画211，每个笔画211包括至少一组透光孔222。在发明的其他实施例中，也可选用其他的表示方法来表示各个数字。
在本发明的其他优选实施例中，所述LED图案220可以是温度显示数字，其可以包括至少三个由7个笔画组成的8 形显示数字和至少一个由至少一个笔画组成的1 形显示数字，或者至少三个由7个笔画组成的8 形显示数字和至少一个由六个笔画组成的已形显示数字，或者至少四个由7个笔画组成的8 形显示数字。
在图1所示的优选实施例中，所述LCD显示屏100为负显示LCD显示屏。在负显示LCD显示屏中，显示内容的颜色就要浅于背景颜色，比如蓝底白字（蓝屏），黑底白字屏（VA段码屏），此类屏相对来说对比度较高，在室内的显示效果要优于正显示LCD显示屏。针对该实现方式，优选采用图3所示的驱动模块。如图3所示，所述驱动模块300包括数显模块310、LCD显示控制模块320和LED显示控制模块330。所述数显模块310用于生成数字显示控制信号。所述LCD显示控制模块320与所述数显模块310电连接，从而接收所述数字显示控制信号，并基于所述数字显示控制信号驱动所述负显示LCD显示屏100生成显示数字的所述LCD显示图案110。同时，所述LED显示控制模块330同样与所述数显模块310电连接，从而接收所述数字显示控制信号，并基于所述数字显示控制信号驱动所述LED图案210中对应笔画211的LED灯240发光，从而生成显示数字的所述LED显示图像220。在本优选实施例中，所述LCD显示图案110可以与所述LED灯发光形成的LED显示图案220一一对应并且彼此完全重叠，这样LCD显示图案110和LED显示图案220同时组成所述LCD和LED混合显示屏的显示图案。在另一优选实施例中， LCD显示图案110和LED显示图案220可以彼此部分重叠，比如LCD显示图案110和LED显示图案220的各个笔画大体上彼此重叠，但是其粗细或者大小上有些微差别。本领域技术人员知悉，在此可以采用本领域中已知的任何处理器、芯片、电路和模块构建上述数显模块310、LCD显示控制模块320和LED显示控制模块330。
在本发明的优选实施例中，所述负显示LCD显示屏100的底色为深色，所述LCD显示图案110为透明或者半透明。这样，所述LCD和LED混合显示屏的显示图案的颜色将与LED灯发出的光的颜色相同。优选地，所述LED显示屏200上设置散射膜270，所述散射膜优选是白色，其同时也可以用作LCD显示屏100的反射膜。
在本发明的优选实施例中，该数显模块310可以是任何已知的时钟模块，也可以是温度检测模块，湿度检测模块等等任何可以生成数字显示控制信号从而控制LCD显示控制模块320和LED显示控制模块330进行数字显示的电路，芯片，或者模块。
本发明的LCD和LED混合显示屏弥补了普通的液晶显示屏在黑暗环境下无法查看，以及LED显示屏在光亮环境下对比度降低，可视效果变差的缺点。实现了在各种环境亮度下，都可以轻松查看的目的，并且可以低功耗进行工作。这使得使用这种混合显示屏的产品可以使用电池供电即可实现长时间续航成为可能。本发明的LCD和LED混合显示屏实际上结合了综合发光和不发光显示屏的优点，进行优势互补，避开他们的缺点。并且降低功耗，使得使用这种显示屏的产品可以在仅由电池供电的模式下是长时间工作成为可能。因此可以应用在仅使用电池的就进行长时间工作的便携产品上。
图4是本发明的LCD和LED混合显示屏的第二优选实施例的组合示意图。如图1所示，所述LCD和LED混合显示屏包括：LCD显示屏100、重叠设置在所述LCD显示屏100后侧的LED显示屏200，以及用于驱动所述LCD显示屏100和所述LED显示屏200的驱动装置300。所述LED显示屏200上设置至少一个LED图案210，每个LED图案210包括多个笔画211，每个笔画211对应至少一个LED灯。所述LCD显示屏100在受到所述驱动装置300驱动通电时会显示至少一个LCD显示图案110。所述LED显示屏200在受到所述驱动装置300驱动时，对应的LED灯会发光，从而形成LED显示图案220。

因此，本发明可以通过硬件、软件或者软、硬件结合来实现。本发明可以在至少一个计算机系统中以集中方式实现，或者由分布在几个互连的计算机系统中的不同部分以分散方式实现。任何可以实现本发明方法的计算机系统或其它设备都是可适用的。常用软硬件的结合可以是安装有计算机程序的通用计算机系统，通过安装和执行程序控制计算机系统，使其按本发明方法运行。
虽然本发明是通过具体实施例进行说明的，本领域技术人员应当明白，在不脱离本发明范围的情况下，还可以对本发明进行各种变换及等同替代。另外，针对特定情形或材料，可以对本发明做各种修改，而不脱离本发明的范围。因此，本发明不局限于所公开的具体实施例，而应当包括落入本发明权利要求范围内的全部实施方式。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
