Description

图像显示装置及图像显示方法 技术领域
本公开实施例涉及一种图像显示装置及图像显示方法。
背景技术
目前，为了实现大屏幕显示，可以使用由多个独立的显示屏拼接而成的显示装置。
现有的由多个显示屏拼接而成的显示装置在安装过程中，在将多个显示屏组装完成之后，可能会发现显示屏被反向放置，即显示屏的放置方向被旋转180°，例如，如图1a和图1b所示，显示装置由四个独立的显示屏ABCD拼接而成，图1a中的四个显示屏ABCD均正向放置，图1b中的显示屏A和B被反向放置，图1b中的显示屏C和D被正向放置，此时，为了保证图1b所示的显示装置能够正常显示图像，需要将四个显示屏ABCD重新组装，这样，既费时又费力。并且，由于显示屏的上边框的宽度(如图1a和图1b所示的a所示)一般小于下边框的宽度(如图1a和图1b所示的b所示)，因此，为了减小显示屏之间的拼缝以改善显示效果，如图1b所示，需要人为地将显示屏A和B反向放置，这样，又会导致显示装置不能正常显示图像。

各显示屏1，被配置为根据接收的相应图像信息显示图像。
本公开实施例提供的上述图像显示装置，通过重力传感器确定对应的显示屏的放置方向，逻辑电路根据重力传感器确定出的显示屏的放置方向的结果自动调整读取存储器中的图像信息的顺序，并将读取的图像信息输出给对应的显示屏，从而保证图像显示装置在显示屏正向放置和反向放置的情况下都能正常显示图像。
在本公开实施例提供的上述图像显示装置中，如图2所示，每个显示屏1可以包括显示面板11(如图2中虚线框所示的部件)和与显示面板11绑定的印刷电路板12；其中，显示面板11可以为液晶显示面板、有机电致发光显示面板或等离子显示面板等平板显示面板，在此不做限定；印刷电路板12的具体结构与现有的印刷电路板的结构类似，在此不做赘述.。在一些实施例中，如图2所示，可以将重力传感器2集成于对应的显示屏1中的印刷电路板12中，这样，增加的重力传感器2不会影响显示屏1的开口率，并且，便于为重力传感器2提供电源。例如，如图2所示，可以将印刷电路板12绑定 于显示面板11的上边框区域内，因此，重力传感器2也位于显示面板11的上边框区域内。当然，也可以将印刷电路板12绑定于显示面板11的下边框区域内，在此不做限定。
在本公开实施例提供的上述图像显示装置中，逻辑电路3可以为现场可编程逻辑器(Field Programmable Gate Array,FPGA)或其他类似的电路器件。逻辑电路3与各显示屏电性连接，可以通过高清晰度多媒体接口(High Definition Multimedia Interface,HDMI)与各印刷电路板12电性连接，从而逻辑电路3可以将读取的相应图像信息输出给各印刷电路板，各印刷电路板控制对应的显示面板显示待显示的图像。例如，可以在逻辑电路3中设置HDMI_TX元件，该HDMI_TX元件可以将图像信息按照HDMI格式输出给各印刷电路板。
当然，在本公开实施例提供的上述图像显示装置中，逻辑电路3还可以通过其他方式与各印刷电路板电性连接，并按照相应的格式将图像信息输出给各印刷电路板，在此不做限定。
需要说明的是，在本公开实施例提供的上述图像显示装置中，逻辑电路3与各重力传感器2电性连接，例如，逻辑电路3与各重力传感器2可以通过导线直接电性连接。
在本公开实施例提供的上述图像显示装置中，逻辑电路3可以包括：用于读取存储器中的图像信息的远程直接数据存取元件(Remote Direct Memory Access,RDMA)，这样，可以通过逻辑电路3中的RDMA读取存储器中的图像信息。当然，也可以通过在逻辑电路3中设置其他类型的元件来读取存储器中的图像信息，在此不做限定。
在本公开实施例提供的上述图像显示装置中，存储器4可以为，例如，双倍速率同步动态随机存储器(Double Data Rate,DDR)，或者，存储器4也可以为其他类型的存储器，在此不做限定。
在本公开实施例提供的上述图像显示装置中，重力传感器2是根据压电效应的原理来工作的。例如，压电效应是指对于不存在对称中心的异极晶体，施加到晶体上的外力除了可以使晶体发生形变以外，还可以改变晶体的极化状态，从而在晶体的内部建立电场，进而产生电压。重力传感器就是利用加速度使晶体发生形变，晶体形变产生电压，从而将加速度转化成电压输出。 由于显示屏在不同的放置状态下会产生不同的加速度从而会使重力传感器产生不同的电压，因此，可以根据重力传感器输出的电压确定显示屏的放置方向。例如，第一控制信号可以为高电平信号，第二控制信号可以为低电平信号，即重力传感器在确定显示屏的放置方向为正向时，向逻辑电路3输出高电平信号；重力传感器在确定显示屏的放置方向为反向时，向逻辑电路3输出低电平信号。又例如，第一控制信号可以为低电平信号，第二控制信号可以为高电平信号，本公开在此不作限定。
在本公开实施例提供的上述图像显示装置中，逻辑电路被配置为：在接收重力传感器输出的第一控制信号时(即重力传感器确定显示屏的放置方向为正向时)，按照由上到下的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由左向右的顺序逐个读取，例如，如图2所示的显示屏EF被正向放置，逻辑电路读取存储器中与显示屏EF对应的图像信息的顺序为由各显示屏的左上方指向该显示屏的右下方(如图2上方所示的箭头所示)。逻辑电路还被配置为：在接收重力传感器输出的第二控制信号时(即重力传感器确定显示屏的放置方向为反向时)，按照由下到上的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由右向左的顺序逐个读取，例如，如图2所示的显示屏GH被反向放置，逻辑电路读取存储器中与显示屏GH对应的图像信息的顺序为由各显示屏的右下方指向该显示屏的左上方(如图2下方所示的箭头所示)。
当然，在本公开实施例提供的上述图像显示装置中，逻辑电路在接收重力传感器输出的第一控制信号时，也可以按照由下到上的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由右向左的顺序逐个读取；而逻辑电路在接收重力传感器输出的第二控制信号时，按照由上到下的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由左向右的顺序逐个读取。或者，逻辑电路在接收重力传感器输出的第一控制信号时，可以按照由上到下的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由右向左的顺序逐个读取；而逻辑电路在接收重力传感器输出的第二控制信号时，按照由下到上的顺序逐行读取存储器中的图像信息，每行图像信息按照由左向右的顺序逐个读取。或者，逻辑电路在接收重力传感器输出的第一控制信号时，还可以按照由下到上的顺序逐行读取存储器中的相应图像信息，每行图像信 息按照由左向右的顺序逐个读取；而逻辑电路在接收重力传感器输出的第二控制信号时，按照由上到下的顺序逐行读取存储器中的相应图像信息，每行图像信息按照由右向左的顺序逐个读取。只需保证在显示屏的放置方向为正向和反向时，对应的图像信息的读取顺序相反即可，本公开对于图像信息的读取方式不做限定。
在本公开实施例提供的上述图像显示装置中，逻辑电路还被配置为对读取的相应图像信息进行同步、放大、画质调整处理，将处理后的相应图像信息输出给对应的显示屏。例如，逻辑电路对各显示屏对应的图像信息进行同步处理，可以保证图像显示装置中的各显示屏同步显示图像。逻辑电路对各显示屏对应的图像信息进行放大处理，例如，可以将各显示屏对应的图像信息放大至所需的分辨率和所需的帧频。例如，在图像显示装置的分辨率为1920×1080，帧频为60Hz时，可以将各显示屏对应的图像信息放大至1920×1080@60Hz。逻辑电路对各显示屏对应的图像信息进行画质调整处理，可以改善图像显示装置中的各显示屏显示图像的品质。
本公开实施例还提供了一种图像显示方法，如图3所示，包括如下步骤：
S301、确定拼接的多个显示屏中各显示屏的放置方向(例如，该多个显示屏可以包括：放置方向被确定为正向的一或多个第一显示屏和/或放置方向被确定为反向的一或多个第二显示屏)；对于放置方向被确定为正向的第一显示屏，执行步骤S302；对于放置方向被确定为反向的第二显示屏，执行步骤S303；
