Description

显示面板、显示器及提高四基色纯色画面显示亮度的方法
本发明要求2015年12月23日递交的发明名称为“显示面板、显示器及提高四基色纯色画面显示亮度的方法”的申请号201510979465.0的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及显示画面处理的方法，尤其涉及一种提高四基色纯色画面显示亮度的方法、显示面板及具有该显示面板的显示器。
背景技术
随着人们节能环保意识的增强以及手机轻薄化的趋势的发展，节能和电池体积轻薄化、续航能力提高的需求越来越被手机品牌制造商以及终端消费者所看重，节能变成手机的重大卖点，RGBW显示面板(基于RGBW(红绿蓝白)四基色显示技术的显示面板)通过增加白像素使得面板的穿透率相较RGB显示面板(基于RGB三基色显示技术的显示面板)有较大的提高,使用子像素共享算法在解析度不变的前提下减少面板1/3的像素数目以降低超高解析度的生产良率风险,同时降低背光功耗40％，又可提高图像对比度的效果。
如图1所示，FHD(Full High Definition，全高清)模式下，RGBW显示面板的cell(单元)开口率为RGB显示面板的1.24倍，在QHD(Quarter High Definition，1/4高清)模式下，RGBW显示面板的cell开口率为RGB显示面板的1.37倍，同时白像素的穿透率接近1，所以采用四基色的面板穿透率是传统面板的1.9～2.0倍。然而，由于RGBW显示面板引入W像素，所以R、G、B的开口率变为原来传统RGB面板的75％，这样RGBW显示面板在显示纯色的R、G或B时亮度没有传统RGB面板亮度高。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图2，为本发明一实施例中的显示面板1的像素阵列示意图。在本实施方式中，该显示面板1为四基色显示面板。该显示面板1包括若干呈阵列式排列的像素单元10，每一像素单元10包括R(红色)像素101、G(绿色)像素102、B(蓝色)像素103、W(白色)像素104四个像素。其中，该显示面板1的W像素104的伽玛值(Gama)设定为第一预设值，该显示面板1的R像素101、G像素102、B像素103设定为小于第一预设值的第二预设值。从而，显示面板1的R像素101、G像素102、B像素103在伽玛中部灰阶的亮度值提高，W像素104的亮度值维持不变，提高了R、G、B像素在亮度上的贡献，提高了显示面板1在显示纯色画面时的亮度。
在本实施方式中，该显示面板1的整个灰阶画面下的伽玛值还设定为第一预设值。从而，该显示面板1的整个灰阶画面下的伽玛曲线符合第一预设值，维持了显示面板1整体显示的较佳效果。
在本实施例中，该第一预设值为2.2，该第二预设值为1.8，显然，该第一预设值和第二预设值也可为其他合适的值，只要能满足第一预设值为显示面板1整体显示的最佳效果值，而第二预设值为低于第一预设值的要求即可。
请一并参阅图3，如图3所示，该R、G、B像素的Gama值从2.2变为1.8后，在伽玛曲线的中部灰阶的亮度值提高，提高了R、G、B像素在亮度上的贡献，提高了显示面板1在显示纯色画面时的亮度。
在本实施方式中，该显示面板1为普通的四基色显示面板经过如下处理步骤后得到：1)在关闭W像素104时，将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值；以及2)在打开W像素104时，将整个显示面板1的灰阶画面调整为第一预设值。其中，由于在对R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值时，W像素 104关闭，因此，W像素104的伽玛值维持为第一预设值不变。
其中，该关闭W像素104指关闭显示面板1上所有的W像素104，该将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值指将显示面板1上所有的R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值。
在一实施方式中，该步骤“在关闭W像素104时，将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值”为：在关闭W像素104时，将R像素101、G像素102、B像素103的伽玛值同时从第一预设值调节为第二预设值。在另一实施方式中，该步骤“在关闭W像素104时，将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值”也可以为：在关闭W像素104时，依次将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值，即，先调节RGB像素中的一种像素，再调节第二种，再调节第三种。
请一并参阅图4，为显示面板1的部分元件示意图。该显示面板1还包括一控制器20以及若干像素电极30，每一像素电极30对应R像素101、G像素102、B像素103、W像素104中的任一个。该控制器20通过调节对应R像素101、G像素102、B像素103的像素电极30的参数将该R像素101、G像素102、B像素103、W像素104的伽玛值从第一预设值调节为第二预设值。
其中，该被调整的像素电极30的参数可为驱动电压等，该控制器20可通过调节该R像素101、G像素102、B像素103对应的像素电极30的驱动电压将该R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值。
其中，关闭W像素104指控制器20控制停止对W像素104施加扫描电压，开启W像素104指控制器20控制对W像素104施加扫描电压。
在本实施方式中，该显示面板1为液晶显示面板，该R像素101、G像素102、B像素103以及W像素104的每一个包括一液晶分子以及对应颜色的滤光片。在其他实施方式中，该显示面板1可为等离子显示面板、电子纸显示面板等。
请参阅图5，为显示器100的模块示意图，该显示器100包括该显示面板 1。该显示器100可为电脑显示屏、手机、电视机等。由于该显示器100采用了该显示面板1，显示器100在显示纯色画面时能够提高显示亮度。
其中，该显示器100也包括其他元件，例如处理芯片、音频芯片等，由于于本发明改进无关，故不在此赘述。
请参阅图6，为本发明一实施例中的提高四基色纯色画面显示亮度的方法的流程图。该方法用于提高显示面板1在显示纯色画面时的显示亮度，包括如下步骤：
关闭显示面板1的W像素104，将显示面板1的R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值(S601)。在一实施方式中，本步骤为将R像素101、G像素102、B像素103的伽玛值同时从第一预设值调节为第二预设值。在另一实施方式中，本步骤为依次将R像素101、G像素102、B像素103的伽玛值从第一预设值调节为第二预设值。其中，在本实施方式中，第一预设值为2.2，第二预设值为1.8。
打开W像素104，将整个显示面板1的灰阶画面调整为第一预设值(S603)。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
