Description

显示器、显示系统和数据处理方法 技术领域
本发明涉及显示技术领域，特别涉及一种显示器、一种显示系统和一种数据处理方法。
背景技术
视频的帧率(Frame rate)是用于测量显示帧数的量度，其测量单位为每秒显示帧数(Frames per Second，FPS)或赫兹(Hz)。已知视频信号的帧率如下表1所示：
表1
Figure PCTCN2014085289-appb-000001
表1中，电影类视频信号的帧率为23.976fps，电视类视频信号可包括例如逐行倒相(Phase Alternating Line，PAL)制式视频信号和国家电视标准委员会(National Television Standards Committee，NTSC)制式视频信号，其中，PAL制式视频信号的帧率为25fps，NTSC制式视频信号的帧率为29.97fps。
同时，不同类型的显示器具有不同的刷新频率，刷新频率指的是屏幕刷新的速度。刷新频率越低，图像闪烁、停顿和抖动的就越厉害，眼睛就越容易疲劳。目前，不同类型的显示器的刷新频率如下表2所示：
表2
CRT显示器 液晶显示器 3D显示器
60Hz-85Hz 60Hz-75Hz 120Hz
表2中，显示器可包括：阴极射线管(Cathode Ray Tube，CRT)显示器、液晶显示器和3D显示器，其中，CRT显示器的刷新频率为60Hz-85Hz，液晶显示器的刷新频率为60Hz-75Hz，3D显示器的刷新频率为120Hz。
显示器接收图像处理单元发送的视频信号，并对接收到的视频信号 进行显示。表1所示为图像处理单元接收到的视频信号的帧率，表2所示为显示器屏幕的刷新频率，从表1和表2可以看出，图像处理单元接收到的视频信号的帧率明显低于显示器屏幕的刷新频率，因此，在现有技术中，图像处理单元在将视频信号发送给显示器之前，需要将视频信号转换为帧率与显示器屏幕的刷新频率一致的视频信号。以帧率为30Hz的视频信号和刷新率为60Hz且分辨率为1366*768的显示器为例，图像处理单元在接收到30Hz的视频信号后，将30Hz的视频信号转换为可供显示器显示的60Hz的视频信号，并向显示器输出该60Hz的视频信号，因此，图像处理单元每秒向显示器传输的像素数据量为1366*768*60＝62945280。
综上所述，在现有技术中，由于图像处理单元的数据传输量和处理量较大，因此极大地增加了图像处理单元的负荷，使得图像处理单元容易成为显示系统的性能瓶颈。

具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图对根据本发明的实施例进行详细描述。
图1为根据本发明的第一实施例的一种显示器的结构示意图，如图1所示，该显示器包括：数据处理单元11和显示装置12，显示装置12具有 设定的刷新频率。数据处理单元11用于将原始数据信号转换为显示数据信号，并将该显示数据信号输出至显示装置12，原始数据信号的帧率为原始频率，显示数据信号的帧率为刷新频率，其中，所述原始数据信号是由图像处理单元输出并且可以由显示装置12以原始频率直接显示的信号。显示装置12用于对显示数据信号进行显示。
原始数据信号和显示数据信号可分别包括若干帧的数据。例如：若原始频率为30Hz，则对于原始数据信号来说，每秒可包括30帧数据；若刷新频率为60Hz，则对于显示数据信号来说，每秒可显示60帧数据。由于显示装置12具有设定的刷新频率，例如：该刷新频率为60Hz，则为了使原始数据信号能够在显示装置12上显示，数据处理单元11会将帧率为原始频率的原始数据信号转换为帧率为刷新频率的显示数据信号，例如：数据处理单元11将帧率为30Hz的原始数据信号转换为帧率为60Hz的显示数据信号。
本实施例中，数据处理单元11包括：传输模块111、存储模块112和数据处理模块113，传输模块111分别与存储模块112和数据处理模块113连接，存储模块112与数据处理模块113连接，数据处理模块113还与显示装置12连接。传输模块111用于接收来自图像处理单元的原始数据信号中的任一帧的数据并将原始数据信号中的帧数据分别输出至存储模块112和数据处理模块113。所述存储模块112用于对原始数据信号中的帧数据进行存储并将其输出至数据处理模块113。数据处理模块113用于根据存储模块112输出的原始数据信号中的帧数据生成设定数量的该帧数据，并将传输模块111输出的原始数据信号中的帧数据和生成的设定数量的该帧数据作为显示数据信号输出至显示装置12。
优选地，设定数量为一个或者多个。其中，数据处理模块113可通过预先设定的数据处理规则，根据存储模块112输出的原始数据信号中的帧数据生成设定数量的该帧数据。所述数据处理规则为在传输模块111输出的原始数据信号中的帧数据之后插入设定数量的该帧数据。具体地，若数据处理规则为在传输模块111输出的原始数据信号中的帧数据之后插入一个该帧数据，则数据处理模块113根据存储模块112输出的原始数据信号中的帧数据生成一个该帧数据；若数据处理规则为在传输模块111输出 的原始数据信号中的帧数据之后插入多个该帧数据，则数据处理模块113根据存储模块112输出的原始数据信号中的帧数据生成多个该帧数据。当设定数量为多个时，数据处理模块113生成设定数量个该帧数据具体方法可包括：数据处理模块113复制出设定数量的该帧数据。
下面通过一个具体的示例对数据处理单元11的工作过程进行详细描述，具体地，以原始频率为30Hz以及刷新频率为60Hz为例进行描述。图2为第一实施例的数据传输的示意图，如图1和图2所示，在显示帧率为30Hz的原始数据信号的情况下，图像处理单元会首先接收帧率为30Hz的原始数据信号。原始数据信号可包括若干帧的数据，假设将帧率为30Hz的原始数据信号中的每一帧的数据定义为：F1、F2、……、F29、F30；显示数据信号可包括若干帧的数据，假设将帧率为60Hz的显示数据信号中的每一帧的数据定义为：f1、f2、f3、f4、……、f57、f58、f59、f60。根据本发明，当图像处理单元接收到帧率为30Hz的原始数据信号时，通过程序(例如，软件、固件、应用程序、代码、指令等)使得图像处理单元不对原始数据信号中的各帧数据进行帧率变换的处理(例如，插值处理)，而是将帧率为30Hz的原始数据信号直接输出给传输模块111。具体地，图像处理单元向传输模块111依次输出原始数据信号中的帧数据F1、F2、……、F29、F30。传输模块111接收到F1之后，将F1分别输出至存储模块112和数据处理模块113。存储模块112对F1进行存储并将F1输出至数据处理模块113。根据预先设定的处理规则(例如，设定数量为一个)，数据处理模块113根据存储模块112输出的F1生成一个F1，此时，显示数据信号中的f1可以为传输模块111输出的F1，显示数据信号中的f2可以为数据处理模块113生成的F1。之后，数据处理模块113将显示数据信号中的f1和f2依次输出至显示装置12。同样地，传输模块111接收到F2之后，将F2分别输出至存储模块112和数据处理模块113。存储模块112对F2进行存储并将F2输出至数据处理模块113。数据处理模块113根据存储模块112输出的F2生成一个F2，此时，显示数据信号中的f3可以为传输模块111输出的F2，显示数据信号中的f4可以为数据处理模块113生成的F2。数据处理模块113将显示数据信号中的f3和f4依次输出至显示装置12。数据处理模块113按照上述对F1和F2的数据处 理方式，依次处理F3至F30，以得出f5至f60，从而使得数据处理单元11将帧率为30Hz的原始数据信号转换为帧率为60Hz的显示数据信号。在上述过程中，由于图像处理单元在接收到原始数据信号后直接将原始数据信号输出至显示器的数据处理单元11，因此图像处理单元每秒向显示器的数据处理单元11传输的像素数据量为1366*768*30＝31472640。与现有技术相比，图像处理单元每秒向显示器传输的像素数据量降低了一半，从而降低了图像处理单元的数据传输量和处理量。
本实施例中，原始数据信号可以为视频信号或者操作指令信号。例如，操作指令信号可以为打开WORD文档的指令信号。在实际应用中，原始数据信号还可以为其他类型的数据信号，此处不再一一列举。
优选地，传输模块111为行缓冲器(Line Buffer)，存储模块112为只读存储器(Read-Only Memory，ROM)。
在本实施例中，数据处理单元11包括在显示器中，但是数据处理单元11可单独地设置。
根据本发明的第二实施例，显示器还可包括：时序控制器(Timing Controller)。本实施例中，优选地，数据处理单元11与时序控制器集成，例如，将数据处理单元11集成于时序控制器中。所述时序控制器可用于对显示装置的显示过程进行控制。本实施例中，时序控制器可采用传统的时序控制器，此处对时序控制器不再具体描述。
图3为根据本发明的第二实施例的显示器的应用示意图，如图3所示，该显示器包括：时序控制器1和显示装置，其中，数据处理单元11与时序控制器1集成，时序控制器1分别与图像处理单元2和显示装置连接。如图3所示，显示装置可包括：栅极驱动器121、源极驱动器122和显示面板123，其中，显示面板123分别与栅极驱动器121和源极驱动器122连接，源极驱动器122与数据处理单元11连接。栅极驱动器121用于向显示面板123输出栅极扫描信号；源极驱动器122用于接收数据处理单元11输出的显示数据信号并将其输出至显示面板123；显示面板123用于在栅极扫描信号的控制下对显示数据信号进行显示。
根据本发明的第二实施例的的显示器包括数据处理单元和显示装置，数据处理单元可将原始数据信号转换为显示数据信号，该原始数据信 号的帧率为原始频率，该显示数据信号的帧率为显示装置的刷新频率，在本实施例中，图像处理单元仅需将原始数据信号直接传输给显示器的数据处理单元，因此，极大地降低了图像处理单元的数据传输量和处理量，从而降低了图像处理单元的负荷，进而提高了显示系统的性能。同时，在本实施例中，由设置在显示器中的数据处理单元对原始数据信号进行处理(即，将原始数据信号转换为显示数据信号)，由此增强了显示器的数据处理能力。
根据本发明的第三实施例，提供了一种显示系统，该显示系统可包括：图像处理单元和显示器。图像处理单元用于向显示器输出原始数据信号。其中，显示器可采用上述实施例提供的显示器，此处省略其详细描述。
在根据本发明的第三实施例的显示系统中，显示器包括数据处理单元和显示装置，数据处理单元可将原始数据信号转换为显示数据信号，该原始数据信号的帧率为原始频率，该显示数据信号的帧率为显示装置的刷新频率。在本实施例中，图像处理单元仅需将原始数据信号直接传输给显示器的数据处理单元，因此极大的降低了图像处理单元的数据传输量和处理量，从而降低了图像处理单元的负荷，进而提高了显示系统的性能。同时，在本实施例中，由设置在显示器中的数据处理单元对原始数据信号进行处理(即，将原始数据信号转换为显示数据信号)，由此增强了显示器的数据处理能力。
图4为根据本发明的第四实施例的一种数据处理方法的流程图，如图4所示，该方法包括以下步骤：
步骤101：通过数据处理单元将原始数据信号转换为显示数据信号，并将该显示数据信号输出至显示装置，其中，显示装置具有设定的刷新频率，原始数据信号的帧率为原始频率，显示数据信号的帧率为刷新频率。
步骤102：通过显示装置对显示数据信号进行显示。
本实施例中，参考图1所示，所述数据处理单元包括：传输模块、存储模块和数据处理模块，传输模块分别与存储模块和数据处理模块连接，存储模块与数据处理模块连接，数据处理模块还与显示装置连接。
因此，步骤101可以包括如下步骤：
(1)通过传输模块接收原始数据信号中的任一帧数据并将该帧数据 分别输出至存储模块和数据处理模块。
(2)通过存储模块对原始数据信号中的帧数据进行存储并将该帧数据输出至数据处理模块。
(3)通过数据处理模块根据存储模块输出的原始数据信号中的帧数据生成设定数量的该帧数据，并将传输模块输出的原始数据信号中的帧数据和所生成的设定数量的该帧数据作为显示数据信号输出至显示装置。
其中，设定数量为一个或者多个。
本实施例提供的数据处理方法可通过上述实施例提供的显示器实现，对显示器的具体描述可参见上述实施例，此处不再赘述。
在根据本发明的第四实施例的数据处理方法中，显示器的数据处理单元可将原始数据信号转换为显示数据信号，该原始数据信号的帧率为原始频率，该显示数据信号的帧率为显示装置的刷新频率。根据本发明的数据处理方法，图像处理单元仅需直接将原始数据信号传输给显示器的数据处理单元，因此极大的降低了图像处理单元的数据传输量和处理量，从而降低了图像处理单元的负荷，进而提高了显示系统的性能。在本实施例中，由设置在显示器中的数据处理单元对原始数据信号进行处理(即，将原始数据信号转换为显示数据信号)，由此增强了显示器的数据处理能力。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也属于本发明的保护范围。
