Description

立体显示装置及其显示控制方法
【技术领域】
本发明涉及显示技术领域，特别是涉及一种立体显示装置及其显示控制方法。
【背景技术】
近几年，立体显示技术发展迅速，成为业界研究的热点。立体显示技术在医疗、广告、军事、展览、游戏等领域有重要的应用。请参阅图1，图1是一种现有技术的立体显示装置的示意图。如图1所示，立体显示装置主要包括液晶显示器10和快门眼镜13。液晶显示器10主要包括液晶显示面板11以及背光模组12。液晶显示面板11可在背光模组12提供照明的情况下交替显示左眼画面和右眼画面。
快门眼镜13包括左眼镜片131以及右眼镜片132。左眼镜片131以及右眼镜片132分别包括两片偏光片（图未示）以及位于两片偏光片中间的液晶层（图未示）。通过向对应的液晶层提供电压，可以分别控制左眼镜片131以及右眼镜片132的开启和关闭。在立体显示过程中，当液晶显示面板11显示左眼画面时，左眼镜片131开启，右眼镜片132关闭，此时左眼画面传送至用户的左眼，用户的右眼看到黑画面。在液晶显示面板11显示右眼画面时，左眼镜片131关闭，右眼镜片132开启，此时右眼画面传送至用户的右眼，用户的左眼看到黑画面。即：由用户的左眼和右眼分别接收到的左眼画面和右眼画面在用户大脑内合成立体画面，进而产生立体显示效果。
请参见图2，图2是图1所示的立体显示装置的工作时序图。如图2所示，该工作时序图的纵坐标表示液晶显示面板11的上下位置，横坐标表示时间。由于现有技术中的背光模组12从上往下分成多个水平区域，因此背光模组12的扫描方式是由上往下依序控制各水平区域开启和开启时间。具体而言，如图2中，背光模组12包括区域S1、S2、S3、S4以及S5共五个水平区域。液晶显示面板11交替显示左眼画面帧和右眼画面帧，其中左眼画面帧的时间为T1，右眼画面帧的时间为T2，T1和T2各代表一个画面帧的时间。在驱动时，信号是依序由上而下向各水平区域相对应的液晶显示面板11提供驱动信号，而液晶像素在收到驱动电压充电后，液晶才开始反应，因此，由于像素设计以及液晶的粘滞特性，需要一段时间L0反应达到稳定。配合全区域S1、S2、S3、S4以及S5信号驱动，由于左眼镜片131开闭时间晚，区域S1的驱动信号已经由左眼画面帧换成了下一个信号右眼画面帧，由于液晶像素存在反应时间L0，造成区域S1同时存在左眼画面帧和右眼画面帧，进而区域S1会看到残影。另外，左眼镜片131开启时间较早，同时向区域S1、S2、S3、S4以及S5提供驱动信号，由于液晶像素存在反应时间L0，区域S1、S2、S3、S4以及S5会不同程度受到上一个右眼画面帧的影响，会出现残影。
承上所述，现有技术立体显示装置中，左右眼信号存在串扰（crosstalk），造成残影，影响立体显示效果。
因此，需要提供一种立体显示装置及其显示控制方法，以解决上述问题。

其中，立体显示装置还包括快门眼镜，快门眼镜包括左眼镜片和右眼镜片，左眼镜片和右眼镜片交替开启，以交替透射左眼画面帧和右眼画面帧。

图5是本发明的立体显示装置的显示控制方法的流程图。
【具体实施方式】
请参见图3，图3是本发明立体显示装置一优选实施例的示意图。如图3所示，本发明的立体显示装置包括液晶显示器20以及快门眼镜23。液晶显示器20进一步包括液晶显示面板21以及背光模块22。其中，液晶显示面板21设置于背光模块22和快门眼镜23之间，并由背光模块22提供照明。
液晶显示面板21用于交替显示左眼画面帧和右眼画面帧。其中，液晶显示面板21划分为从两侧向中间依序连续分布的多个显示区域，在本实施例中，液晶显示面板21划分为五个显示区域。五个显示区域分别为显示区域S11、S12、S13、S14以及S15，显示区域S11和S15为液晶显示面板21的最外侧显示区域，显示区域S12和S14为液晶显示面板21的次外侧显示区域，显示区域S13为液晶显示面板21的中间显示区域。
其中，液晶显示面板21的扫描方式为从液晶显示面板21的中间向两侧的扫描方式依序驱动显示区域S13、S12和S14以及S11和S15。即，首先驱动显示中间显示区域S13，然后驱动显示次外侧显示区域S12和S14，最后驱动显示最外侧显示区域S11和S15。
背光模块22包括多个分别与液晶显示面板21的多个显示区域一一对应的背光单元。在本实施方式中，背光模块22包括背光单元S1、S2、S3、S4以及S5。其中，背光单元S1、S2、S3、S4以及S5分别与液晶显示面板21的显示区域S11、S12、S13、S14以及S15一一对应。背光单元S1、S2、S3、S4以及S5开启的时序配合显示区域S11、S12、S13、S14以及S15的扫描方式进行，先开启中间的背光单元S3，接着开启背光单元S2、S4，最后开启两侧的背光单元S1和S5，以使背光模块22中的各背光单元在其对应的显示区域接收到一画面帧的驱动信号且显示区域的液晶像素反应后才开启，并且在显示区域开始接收另一画面帧的驱动信号时关闭。此外，在本实施方式中，背光单元S1、S2、S3、S4以及S5的开启维持时间相同。
快门眼镜23包括左眼镜片231和右眼镜片232，并可通过红外信号、蓝牙信号或者其他通讯方式与液晶显示面板21进行同步。左眼镜片231和右眼镜片232可根据液晶显示面板21产生的同步信号交替开启，以交替透射左眼画面帧和右眼画面帧。
请参见图4，图4是图3所示的立体显示装置的一工作时序图。如图4所示，本实施例的液晶显示面板21交替显示左眼画面帧和右眼画面帧。其中，左眼画面帧的时间为T1，右眼画面帧的时间为T2，T1和T2各代表一个画面帧的时间。
在左眼画面帧的时间T1中，首先驱动显示中间显示区域 S13，待显示区域S13的液晶像素反应后才开启背光单元S3，在显示区域S13开始接收右眼画面帧的驱动信号时关闭背光单元S3。然后驱动显示次外侧显示区域S12和S14，待显示区域S12和S14的液晶像素反应后才开启背光单元S2和S4，在显示区域S12和S14开始接收右眼画面帧的驱动信号时关闭背光单元S2和S4。最后驱动显示最外侧显示区域S11和S15，待显示区域 S11和S15的液晶像素反应后才开启背光单元 S1和S5，在显示区域S11和S15开始接收右眼画面帧的驱动信号时关闭背光单元S1和S5。其中，液晶像素反应时间为L。
其中，左眼镜片231的开始时间始于液晶显示面板21中最先扫描的显示区域S13的液晶像素接收到左眼画面帧的驱动信号并达到稳定时刻，结束于最后扫描的显示区域S11和S15的液晶像素开始接收右眼画面帧的驱动信号的时刻。而右眼镜片232的开启时间开始于液晶显示面板21的最先扫描的显示区域S13的液晶像素接收到右眼画面帧的驱动信号并达到稳定的时刻，结束于最后扫描的显示区域 S11和S15的像素开始接收左眼画面帧的驱动信号的时刻。
相比于现有技术中立体显示装置，本实施例的立体显示装置通过从液晶显示面板21的中间向两侧的扫描方式依序驱动显示区域S13、S12和S14以及S11和S15，降低了液晶显示面板21的扫描时间，进而增加了背光单元S1、S2、S3、S4以及S5的开启维持时间，此外，背光单元S1、S2、S3、S4以及S5在液晶像素反应后才开启，由此最大化了各背光单元开启的时间，使得本发明的立体显示装置不需要大电流驱动便可减少立体显示装置产生的串扰，进而降低残影的产生，以最少的功率消耗实现立体显示装置显示品质的改善，提升了用户的体验效果。
值得注意的是，前文以液晶显示面板21和背光模块22划分为5个区域为例进行说明，然而在本发明的其他实施例中，液晶显示面板21也可以划分成偶数个显示区域，例如，以六个显示区域为例。六个显示区域分别为显示区域S21、S22、S23、S24、S25以及S26，其中，显示区域S21和S26为液晶显示面板21的最外侧显示区域，显示区域S22和S25为液晶显示面板21的次外侧显示区域，显示区域S23和S24为液晶显示面板21的中间显示区域。
同理，背光模块22此时也配合划分为与显示区域S21、S22、S23、S24、S25以及S26分别一一对应的六个背光单元。并且，液晶显示面板21和背光模块22包括偶数个区域及背光单元时，其工作方式和前述的实施方式相同，在此不再赘述。
请参见图5，图5是本发明的立体显示装置的显示控制方法的流程图。如图5所示，本发明的显示控制方法包括以下步骤：
步骤501：控制液晶显示面板21交替显示左眼画面帧和右眼画面帧；其中，液晶显示面板21划分为从两侧向中间依序连续分布的多个显示区域，并依照从液晶显示面板21的中间向两侧的扫描方式依序驱动多个显示区域；
步骤502：设置多个背光单元，多个背光单元分别与多个显示区域一一对应，控制多个背光单元依序开启，使得各背光单元在其对应的显示区域接收到一画面帧的驱动信号且显示区域的液晶像素反应后才开启，并在显示区域开始接收另一画面帧的驱动信号时关闭；
步骤503：控制快门眼镜23的左眼镜片231和右眼镜片232交替开启，以交替透射左眼画面帧和右眼画面帧。
以上步骤的相关技术细节可参阅上文的详细描述，因此于此不再赘述。
综上所述，本发明的立体显示装置及其显示控制方法，通过从液晶显示面板的中间向两侧的扫描方式依序驱动各显示区域，降低了液晶显示面板的扫描时间，此外，各背光单元在液晶像素反应后才开启，由此最大化了各背光单元开启的时间，降低立体显示装置的功率消耗需求，使得本发明的立体显示装置不需要大电流驱动便可减少立体显示装置产生的串扰，进而降低残影的产生，以低功率消耗实现立体显示装置显示品质的改善。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
