Description

视频数据显示装置及其显示方法 技术领域
本发明关于一种视频数据显示装置,尤其是在由多个显示面板所构成的显示系统中,利用一组视频数据驱动多个显示面板进行显示的装置。本发明还涉及此视频数据显示装置的显示方法。
背景技术
当显示系统中存在多个显示面板时,为了让各个显示面板能够分别显示不同的画面,一般而言需要使用多组不同的视频数据来驱动不同的显示面板。为此,显示系统除了必须为每个显示面板设置各自的显示驱动电路外,还必须为每个显示面板设置各自的视频数据处理器,以利用视频数据处理器分别接收并处理不同的显示讯号,进而提供给不同的显示驱动电路来驱动各个显示面板。
然而,设置多个视频数据处理器必然会增加显示系统的成本。况且,显示系统可能还需要对显示讯号进行各种前处理(例如:分辨率调整),来形成并提供多组不同的显示数据以驱动各个显示面板,这同样也会造成显示系统的成本增加。尤其在车用电子、物联网或智能家庭等领域时常需要应用仅显示简单信息的多个显示面板,在这些领域为了驱动多个显示面板所耗费的成本俨然为业界亟需解决的问题。
鉴于此,本发明提供一种视频数据显示装置,其可以让多个显示面板透过一组视频数据来显示,故可解决上述问题。
发明内容
本发明的目的,在于提供一种视频数据显示装置及其显示方法,其中虽使各个显示驱动电路虽然由同一个视频数据处理器接收相同视频数据,然而透过各个显示驱动电路的数据变换器分别对该视频数据进行变换,即可分别形成不同的子视频数据。据此,仅需要一组视频数据搭配一个数据处理器即可驱动数个显示面板显示不同的画面,而且不需要对显示讯号进行分辨率调整等前处理,能够有效降低显示系统的整体成本。
本发明关于一种视频数据显示装置,其包含一视频数据处理器及数个显示驱动电路。该视频数据处理器输出一视频数据。该些显示驱动电路分别耦接于该视频数据处理器以接收该视频数据。各该显示驱动电路包含一数据变换器及一驱动讯号产生器。该数据变换器对该视频数据进行变换以形成一子视频数据并传输至该驱动讯号产生器。该数据变换器对该视频数据进行以下三种处理的至少一种:将该视频数据的数据进行取代、产生与该视频数据不同的空白间隙信息、产生新的空白间隙信息插入该视频数据中。

具体实施方式
为了使本发明的结构特征及所达成的功效有更进一步的了解与认识,特用较佳的实施例及配合详细的说明,说明如下:
在说明书及权利要求当中使用了某些词汇指称特定的组件,然而,所属本发明技术领域中具有通常知识者应可理解,制造商可能会用不同的名词称呼同一个组件,而且,本说明书及权利要求并不以名称的差异作为区分组件的方式,而是以组件在整体技术上的差异作为区分的准则。在通篇说明书及权利要求当中所提及的“包含”为一开放式用语,故应解释成“包含但不限定于”。再者,“耦接”一词在此包含直接及间接的连接手段。因此,若文中描述一第一装置耦接一第二装置,则代表第一装置可直接连接第二装置,或可透过其他装置或其他连接手段间接地连接至第二装置。
请参阅图1,其为本发明实施例的视频数据显示装置1的架构图。如图所示,视频数据显示装置1包含一视频数据处理器(Video Processor)11及数个显示驱动电路(Display Driver Circuit)12。该视频数据处理器11分别耦接各该显示驱动电路12。该视频数据处理器11可输出一视频数据VD,并由各该显示驱动电路12接收该视频数据VD。该视频数据显示装置1可供应用于包含数个显示面板21、22、23的显示系统中,各该显示驱动电路12分别耦接各该显示面板21、22、23,以驱动各该显示面板21、22、23显示画面。
请一并参照图2所示,在本实施例中,各该显示驱动电路12分别包含一数据接收器121、一数据变换器122及一驱动讯号产生器123。该数据接收器121由该视频数据处理器11接收该视频数据VD。并且,该数据接收器121可以对该视频数据VD的接口标准格式进行转换。举例而言,若该视频数据VD原先为高画质多媒体接口(High Definition Multimedia Interface,HDMI)、低电压差动讯号传输(Low Voltage Differential Signaling,LVDS/LDI)、OpenLDI或Serial R/G/B等格式,该数据接收器121可以将其转换为RGB格式。其中,接口标准格式的种类繁多,故该数据接收器121转换前后的接口标准格式并不以上述范例为限。
该数据变换器122耦接于该数据接收器121,以接收经由该数据接收器121处理后的视频数据VD’。然而,在本发明部分实施例中,若该视频数据VD的接口标准格式不需要被转换,亦可省略该数据接收器121,直接由该数据变换器122接收该视频数据VD。该数据变换器122对该视频数据VD’进行变换,所述变换至少包含以下三种处理的至少一种:将该视频数据VD’的数据进行取代、产生与该视频数据VD’不同的空白间隙(Blanking)信息、产生新的空白间隙信息插入该视频数据VD’中。该数据变换器122完成变换该视频数据VD’后,系形成一子视频数据VS并传输至该驱动讯号产生器123。
该驱动讯号产生器123耦接于该数据变换器122,该数据变换器122完成变换该视频数据VD’后,系形成一子视频数据SVD并传输至该驱动讯号产生器123。该驱动讯号产生器123可接收该子视频数据SVD,并依据该子视频数据SVD产生驱动显示面板所需的驱动讯号DS(例如源极驱动讯号,甚至包含闸极驱动讯号或公共驱动讯号等)。藉此,驱动讯号DS即可用来驱动各该显示面板21、22、23显示该子视频数据SVD。此外,在本发明部分实施例中,该驱动讯号产生器123还可以依据该子视频数据SVD产生驱动显示面板时所需的控制讯号(例如源极时序信号或门极时序信号等)。
请参照图3所示,该显示面板21耦接于该显示驱动电路12,因此,该驱动讯号产生器123所生成的驱动讯号DS(在部分实施例中还可以包含控制讯号)即可用来驱动显示面板21,以显示子视频数据SVD。在本实施例中由于存在三个显示面板21、22、 23,藉由各该显示驱动电路12的数据变换器122分别对该视频数据VD’进行变换,即可分别形成不同的子视频数据SVD,故得以驱动各该显示面板21、22、23显示不同的画面。
以下将对该数据变换器122所执行的三种变换进行详细说明:
请参照图4所示,其为一实施例的数据变换器122对该视频数据VD’所执行的变换。该视频数据VD’包含一画面数据DD及一空白间隙区域BA,其中该画面数据DD即为欲在显示面板上显示的内容,该空白间隙区域BA则不具有显示数据,但为各种接口标准格式都需要的缓冲区域。在本发明中,各该显示面板21、22、23可供显示完整或一部分的画面数据DD,例如该显示面板21就用来在一显示区域DA1中显示一部分的画面数据DD。该数据变换器122接收该视频数据VD’后,可以将该视频数据VD’于显示区域DA1以外的数据进行取代,以舍弃位于显示区域DA1以外的画面数据DD及/或空白间隙区域BA。据此,只有一部分的画面数据DD会保留在显示区域DA1中。
另一方面,在本实施例中,由于在显示区域DA1右侧(依图面而言)会保有被截断的画面数据DD,而通常接口标准格式会需要留有一空白间隙进行缓冲才能正常显示,因此该数据变换器122还可以产生与该视频数据VD’不同的空白间隙信息,并且置换在显示区域DA1右侧的画面数据DD。据此,经由该数据变换器122变换所形成的子视频数据SVD1亦包含一子画面数据DD1及一空白间隙区域BA1,该子画面数据DD1为该视频数据VD’一部分的画面数据DD,且该空白间隙区域BA1会围绕该子画面数据DD1,使得该驱动讯号产生器123能够正确依据该子视频数据SVD1驱动该显示面板21进行显示。
请参照图5所示,类似地,另一个数据变换器122在接收同一个视频数据VD’后,也可以将该视频数据VD’于显示区域DA2以外的数据进行取代,而保留在该显示区域2中的画面数据DD和保留在前述显示区域DA1中的画面数据DD是画面数据DD的不同部分。然而,除了产生与该视频数据VD’不同的空白间隙信息来置换位在显示区域DA1左、右两侧的画面数据DD外,虽然显示区域DA2下侧(依图面而言)本已保有空白间隙,该数据变换器122仍然可以利用与该视频数据VD’不同的空白间隙信息来置换位在显示区域DA2下侧的画面数据DD。据此,经由该数据变换器122变换所形成的子视频数据SVD2会包含更小范围的一子画面数据DD2。
请参照图6所示,相较于前述图5的实施例,倘若该子视频数据SVD2需要显示于尺寸较大的显示面板22,然而所需显示的子画面数据DD2并未增加时,该数据变换器122仅需简单透过框选较大的显示区域DA2,再利用与该视频数据VD’不同的空白间隙信息来置换不需要的显示数据DD,即可形成具有相同子画面数据DD2及较大空白间隙区域BA1的适当子视频数据SVD2。
请参照图7所示,其为另一实施例的数据变换器122对该视频数据VD’所执行的变换。该数据变换器122除了执行前述变换外,还可以产生新的空白间隙信息插入该视频数据VD’中。举例而言,该数据变换器122将该视频数据VD’于显示区域DA1以外的数据进行取代后,可以直接产生新的空白间隙信息插入在显示区域DA1右侧(依图面而言)。据此,经由该数据变换器122变换所形成的子视频数据SVD1会具有更大的显示区域DA1’,在显示区域DA1’中亦包含一子画面数据DD1及围绕该子画面数据DD1的空白间隙区域BA1,使得该驱动讯号产生器123能够正确依据该子视频数据SVD1驱动该显示面板21进行显示。
实际上,由于本发明实施例的数据变换器122能够进行将该视频数据VD’的数据进行取代、产生与该视频数据VD’不同的空白间隙信息、产生新的空白间隙信息插入该视频数据VD’中等三种处理的一种或多种,实际应用于显示系统中时,无论数个显示面板21、22、23的尺寸或所应显示的内容为何,各该数据变换器122都能轻易产生 对应的子视频数据SVD来让驱动讯号产生器123驱动各该显示面板21、22、23。如图8所示,该数据变换器122将该视频数据VD’于显示区域DA2以外的数据进行取代后,除可以以利用与该视频数据VD’不同的空白间隙信息来置换位在显示区域DA2左侧、下侧的画面数据DD,还可以再产生新的空白间隙信息插入在显示区域DA2右侧(依图面而言),以产生对应具有更大的显示区域DA2’的子视频数据SVD2来让驱动讯号产生器123驱动该显示面板22。
值得注意的是,各该数据变换器122如何变换该视频数据VD’的模式,可以预先储存于非挥发性内存中,且可以储存多组不同的变换模式,而得以经由一外部控制讯号选用各该数据变换器122的变换模式,使得应用本发明各实施例的视频数据显示装置1的产品设计灵活度更高。此外,前述子画面数据的分辨率会小于或等于该视频数据的画面数据的分辨率,举例而言,当该视频数据的画面数据的分辨率为600x200,前述子画面数据的分辨率可以为200x200。
综上所述,藉由实施本发明的视频数据显示装置,各个显示驱动电路虽然由同一个视频数据处理器接收视频数据,然而透过各个显示驱动电路的数据变换器分别对该视频数据进行变换,即可分别形成不同的子视频数据,以驱动各该显示面板显示不同的画面。据此,相较于现有技术需要设置多个视频数据处理器以使用多组不同的视频数据来驱动不同的显示面板,采用本发明视频数据显示装置仅需要一组视频数据搭配一个数据处理器即可达到相同效果,而且不需要对显示讯号进行分辨率调整等前处理,能够有效降低显示系统的整体成本。
上文仅为本发明的较佳实施例而已,并非用来限定本发明实施的范围,凡依本发明权利要求范围所述的形状、构造、特征及精神所为的均等变化与修饰,均应包括于本发明的权利要求范围内。
