Description

避免立体显示装置亮度不均的方法 技术领域
本发明涉及立体显示装置，特别是涉及一种避免立体显示装置亮度不均的方法。
 背景技术
随着液晶显示装置的发展，能够呈现立体影像的立体显示装置（3D display device）已逐渐进入市场并将成为下一世代液晶显示装置的发展方向。
快门式眼镜（shutter glasses）为一种主动快门式立体显示技术。快门式眼镜的频率通常固定为60赫兹（Hertz；Hz），而液晶显示装置的屏幕刷新率（screen Shutter Glasses）为120赫兹或240赫兹。
由于液晶显示装置的响应时间较慢（＞3毫秒），且液晶显示装置的驱动方式通常采用的是保持型（holding type），因此快门式立体显示技术通常需要搭配背光扫描（backlight scanning）技术或背光闪烁（backlight blinking）技术。
请参阅图1至图3，图1为现有快门式立体显示技术中白色影像（即灰阶L255）作为左眼影像，黑色影像（即灰阶L0）作为右眼影像的示意图，图2为图1中灰阶L0的电压示意图，图3为图1中灰阶L255的电压示意图。
图1的快门式立体显示技术采用一图框级性转换（1 frame polarity inversion）驱动，亦即每一图框变换极性一次，因此左眼影像（包括图框1、图框3、图框5、图框7以及图框9）皆为正极性电压驱动，右眼影像（包括图框2、图框4、图框6以及图框8）皆为负极性电压驱动。如图2所示，灰阶L0的正极性电压V+与共同电压VCOM的电压差以及灰阶L0的负极性电压V-与共同电压VCOM的电压差小。如图3所示，灰阶L255的正极性电压V+’与共同电压VCOM的电压差以及灰阶L255的负极性电压V-’与共同电压VCOM的电压差大。由于左眼影像（包括图框1、图框3、图框5、图框7以及图框9）皆为正极性电压驱动，右眼影像（包括图框2、图框4、图框6以及图框8）皆为负极性电压驱动，使得液晶显示装置的固定位置都维持相同极性电压驱动，造成立体影像残留（3D image sticking）。
请参阅图4，图4为避免上述立体影像残留采用的快门式立体显示技术。图4的快门式立体显示技术采用两图框级性转换（2 frame polarity inversion）驱动，亦即每两图框变换极性一次，因此如图4所示，左眼影像（包括图框1、图框3、图框5、图框7以及图框9）由正极性电压及负极性电压轮流驱动，右眼影像（包括图框2、图框4、图框6以及图框8）也由正极性电压及负极性电压轮流驱动，可避免立体影像残留。
请参阅图5，图5为图4中白色影像（即灰阶L255）作为左眼影像及右眼影像时一画素在各图框的亮度示意图。由于图5采用两图框级性转换驱动中且为低色偏设计（low color washout），当一图框与前一图框为相同极性电压驱动时，则画素的亮度为亮，如图框2、图框4、图框6以及图框8，当一图框与前一图框为相反极性电压驱动时，则画素的亮度为暗，如图框1、图框3、图框5、图框7以及图框9。因此，两图框级性转换在显示立体影像时虽然能解决立体影像残留的问题，但会造成不同图框亮度不一致的问题。
因此需要对现有技术中两图框级性转换驱动在显示立体影像时亮度不一致的问题提出解决方法。

 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。
请同时参阅图6及图7，图6为根据本发明实施例的避免立体显示装置亮度不均的方法流程图，图7为白色影像（即灰阶L255）作为左眼影像及右眼影像时一个画素在各图框的亮度示意图。
所述立体显示装置采用两图框级性转换（2 frame polarity inversion）驱动，亦即每两图框变换极性一次，因此如图7所示，显示左眼影像的图框1、图框3、图框5、图框7以及图框9由正极性电压及负极性电压轮流驱动，显示右眼影像的图框2、图框4、图框6以及图框8也由正极性电压及负极性电压轮流驱动，因次可避免图1立体影像残留的问题。更明确地说，立体显示装置用于轮流显示左眼影像以及右眼影像，于本实施例中，奇数图框显示左眼影像，偶数图框显示右眼影像。
于步骤S600中，根据一珈玛电压曲线（gamma voltage curve）产生多组珈玛电压。所述多组珈玛电压的数量小于立体显示装置所能显示的灰阶数量。于图7之实施例中，灰阶数量为256。
于步骤S610中，接收一原始灰阶资料。所述原始灰阶资料为左眼影像或右眼影像欲显示之灰阶，于图7之实施例中，灰阶值可以为灰阶L0至灰阶L255之其中一者。
于步骤S620中，判断所述原始灰阶资料为一左眼影像的灰阶资料或一右眼影像的灰阶资料。当判断所述原始灰阶为左眼影像的灰阶资料时，执行步骤S630，当判断所述原始灰阶为右眼影像的灰阶资料时，执行步骤S640。
于步骤S630中，根据所述原始灰阶资料从一第一白平衡追踪查找表（white tracking look-up table）查找多个颜色的灰阶。执行步骤S650。
于步骤S640中，根据所述原始灰阶资料从一第二白平衡追踪查找表查找多个颜色的灰阶。执行步骤S650。
所述多个颜色的灰阶至少包括一第一颜色的灰阶、一第二颜色的灰阶以及一第三颜色的灰阶。于一实施例中，所述第一颜色为红色，所述第二颜色为绿色，所述第三颜色为蓝色。于另一实施例中，所述多个颜色可以为其他颜色。
于步骤S650中，根据所述多个颜色的的灰阶显示一对应所述原始灰阶资料的灰阶。
如上所述，由于所述多组珈玛电压的数量小于立体显示装置所能显示的灰阶数量，所以所述第一白平衡追踪查找表以及所述第二白平衡追踪查找表用于根据所述多组珈玛电压，储存所述原始灰阶资料与多个颜色的灰阶的对应关系，更明确地说，所述第一白平衡追踪查找表以及所述第二白平衡追踪查找表能使珈玛电压进行分压以对应至所能显示的灰阶数量。
本发明的避免立体显示装置亮度不均的方法只需要一组珈玛电压曲线（步骤S600），通过使用两组白平衡追踪查找表分别调节左眼影像与右眼影像的电压分配，使得立体显示装置不仅能解决立体影像残留的问题，也能解决不同图框时亮度不一致的问题。更明确地说，珈玛电压通过白平衡追踪查找表进行分压以使立体显示装置能显示256阶。
请参阅图8，图8为一白平衡追踪查找表的例子，白平衡追踪查找表用于调整各灰阶的色度，举例来说，当要显示灰阶L235时，红色灰阶为243，绿色灰阶为238，蓝色灰阶为219，不仅能使画面具有良好的色度，也能使各图框显示的画面具有均匀的亮度。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
