具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
随着显示技术的发展，激光投影被广泛应用于商业、教学等领域。激光投影使用投影显示设备实现在屏幕上的投影显示，例如激光电视。投影显示设备中最主要的工作模块为图像显示模块，该模块包括数字微镜器件，数字微镜器件上紧密排列了80万至100万个镜片，每个镜片都可以独立向正负方向翻转，光源通过这些镜片反射到屏幕上直接形成图像，其中，一个镜片表示一个像素，也即一个镜片反射的光即为最终形成的图像的一个像素点。在屏幕尺寸固定的情况下，图像的像素点越多，图像的分辨率(单位面积中的像素点数量)越高，投影显示的画质也就越好。
但是，随着人们对投影屏幕的尺寸的需求不断提高，采用相关技术中的投影显示设备进行投影，图像的像素点数量不变，但是单位面积中的像素点数量，也即分辨率变低，因此导致投影显示的画质无法满足显示需求。
本申请提供的投影显示设备、方法及系统，旨在解决相关技术的如上技术问题。

控制装置100也可以是智能设备，如移动终端100B、平板电脑、计算机、笔记本电脑等，其可以通过本地网(LAN，Local Area Network)、广域网(WAN，Wide Area Network)、无线局域网(WLAN，Wireless Local Area Network)或其他网络与激光电视200之间通信，并通过与激光电视200相应的应用程序实现对激光电视200的控制。例如，使用在智能设备上运行的应用程序控制激光电视200。该应用程序可以在与智能设备关联的屏幕上通过直观的用户界面(UI，User Interface)为用户提供各种控制。

在一些实施例中，控制装置100可是一种智能设备。如：控制装置100可根据用户需求安装控制激光电视200的各种应用。

图3中示例性示出了根据示例性实施例中激光电视200的硬件结构示意图。为了便于说明，图3中激光电视200以激光投影设备和可升降屏幕分离设置为例进行示意。

本申请中，除了激光投影设备和可升降屏幕分离设置的方式，为了减小占用空间，另一种设置方式中，将激光投影设备1和可升降屏幕2做成一体。作为示例，激光电视200将激光投影设备和可升降屏幕集成在电视柜体中。
实施例一
在投影屏幕的尺寸增大时，为了提高投影显示画质，需要提高图像的分辨率，因此可以在投影显示设备中设置多个数字微镜器件。图4为本申请实施例提供的一种投影显示设备的结构示意图，如图4所示，本实施例提供的投影显示设备包括图像处理模块11、多个显示控制模块12、多个数字微镜器件13、多个透镜14以及合成棱镜15。其中，多个显示控制模块12和多个数字微镜器件13一一对应连接。多个透镜14位于合成棱镜15和多个数字微镜器件13之间，和多个数字微镜器件13一一对应设置。合成棱镜15对应多个透镜14设置。
在本实施例中，由于设置了多个数字微镜器件13以及与其一一对应连接的多个显示控制模块12，因此，相应地，需要对待显示图像的图像数据进行分解，并分别发送给多个显示控制模块12。
具体地，图像处理模块11可以对待显示图像的图像数据进行分解处理，并将分解获得的多个子图像的图像数据分别发送给多个显示控制模块12。其中，子图像的数量与显示控 制模块12的数量一致。
在一个示例中，图像处理模块11可以包括现场可编程逻辑门阵列(Field Programmable Gate Array，简称FPGA)。由于FPGA的硬件结构比较特殊，因此可以利用事先编辑的逻辑结构文件调整内部结构，利用约束的文件来调整不同逻辑单元的连接和位置，妥善处理好数据线路径，具有很好的灵活性和适应性，方便开发和应用。尤其在处理图像数据时，FPGA可以有效保证数据的分解速度。
接下来，为了输出子图像的显示信号，需要控制数字微镜器件13的镜片进行翻转，因此需要将子图像的图像数据转化为控制信号。
具体地，多个显示控制模块12，均与图像处理模块11连接，可以将接收到的子图像的图像数据转化为控制信号，并将控制信号发送给与其对应连接的数字微镜器件13，从而数字微镜器件13可以根据对应的显示控制模块12输出的控制信号，控制镜片进行翻转，输出子图像的显示信号。
其中，显示信号可以为用于投影显示的光信号。一个显示信号中包含多个像素。
在一个示例中，显示控制模块12可以为专用集成电路(Application Specific Integrated Circuit，简称ASIC)。其体积小、可靠性高，能够实现数据的快速转化。
最后，透镜14可以将对应的数字微镜器件13输出的子图像的显示信号透射后，传输至合成棱镜15。合成棱镜15将经多个透镜14透射后的多个子图像的显示信号，合成待显示图像的显示信号。其中，待显示图像的显示信号用于投影显示待显示图像。
举例来说，在实际应用中，若每个数字微镜器件可以输出的子图像的显示信号包含的像素为2048×2192个，也即每个子图像的像素点为2048×2192个，若数字微镜器件的数量为n个，则最终合成的待显示图像的显示信号包含的像素为n×2048×2192个，也即待显示图像的像素点为n×2048×2192个，相应地，单位面积的像素点数量，也即分辨率，相比于只使用一个图像显示模块时提升了n倍。
图5为本申请实施例提供的合成待显示图像的显示信号的光路示意图，如图5所示，多个透镜14位于合成棱镜15和多个数字微镜器件13之间，和多个数字微镜器件13一一对应设置。合成棱镜15对应多个透镜14设置。
实际应用中，透镜14可以将对应的数字微镜器件13输出的子图像的显示信号透射后，传输至合成棱镜15。然后，合成棱镜15可以对经多个透镜14透射后的多个子图像的显示信号的光传输路径进行调节，如图5所示，当子图像的显示信号为两个时，合成棱镜15可以保持其中一个显示信号的光传输路径不变，而将另一个显示信号通过一个反射界面对光传输路径进行调节，使其与保持不变的一个显示信号的光传输路径相一致，从而可以将两个子图像的显示信号，合成为待显示图像的显示信号。
在一个示例中，透镜14可以为全内反射(Total Internal Reflection，简称TIR)透镜， 合成棱镜15可以为偏振分光棱镜(Polarization Beam Splitter，简称PBS)。TIR透镜采用全反射原理，可以对光进行收集，因此可以将子图像的显示信号更好地传输给合成棱镜，有效避免透射损失。PBS是一种用于分离光线的水平偏振和垂直偏振的光学元件，具有应力小、消光比高、成像质量好、光束偏转角小等特点，因此可以很好地应用于本申请实施例中的光传输路径调节。
图6为本申请实施例提供的又一种投影显示设备的结构示意图，如图6所示，在上述实施例一的基础上，本实施例提供的投影显示设备还包括信号接收模块16和编解码模块17。
在一种可能的应用场景中，待投影显示的内容为视频，基于投影显示的基本原理，需要将待显示视频的视频数据，转化为一帧帧的待显示图像的图像数据。
具体地，可以使用信号接收模块16接收信号源发送的待显示视频的视频数据，并将其发送给与其相连接的编解码模块17，编解码模块16可以对视频数据进行编码和解码处理，获得待显示图像的图像数据，该待显示图像的图像数据可以为差分信号，并将该待显示图像的图像数据发送给与其相连接的图像处理模块11，以备图像处理模块11对待显示图像的图像数据进行分解处理。
在一个示例中，编解码模块16可以为系统级芯片(System on Chip，简称SOC)。SOC为一体化的控制器，体积小、处理速度快，从而能够快速实现对视频数据的编解码处理。本实施例提供的投影显示设备，包括图像处理模块、多个显示控制模块、多个数字微镜器件、多个透镜以及合成棱镜。图像处理模块可以对待显示图像的图像数据进行分解处理，并将分解获得的多个子图像的图像数据分别发送给多个显示控制模块，显示控制模块将接收到的子图像的图像数据转化为控制信号，以使数字微镜器件基于该控制信号，输出子图像的显示信号，接下来，合成棱镜将多个子图像的显示信号，合成用于投影显示待显示图像的，待显示图像的显示信号。也就是说，本申请实施例采用多个数字微镜器件，输出多个子图像的显示信号，再采用合成棱镜将其合成待显示图像的显示信号，用于投影显示，由于投影显示的分辨率由数字微镜器件决定，因此采用多个数字微镜器件可以提升投影显示的分辨率，从而实现高分辨率显示，进而有效提高投影显示画质。
实施例二
在上述实施例一的基础上，在一种实施方式中，为了进一步提高投影显示的分辨率，还可以对每帧子图像进一步做分帧处理。相应地，显示控制模块可以包括分帧模块和处理模块。
其中，分帧模块与图像处理模块连接，可以对接收到的每帧子图像的图像数据进行分帧处理，获得子图像对应的多帧图像数据。举例来说，图7为本申请实施例提供的分帧处 理的示意图，如图7所示，左侧为分帧处理前的子图像，子图像中每个小格代表一个像素点，分帧处理时，会将每个像素点分为多个子像素点，例如A、B、C、D，即可获得右侧图所示的子图像对应的多帧图像。该多帧图像包含了由全部的A像素点构成的子图像，由全部的B像素点构成的子图像，由全部的C像素点构成的子图像，以及由全部的D像素点构成的子图像。也就是说，通过如图所示的分帧处理，可以将分辨率提高4倍。
相应地，为了输出子图像的显示信号，处理模块与分帧模块连接，可以针对每帧子图像，将子图像对应的多帧图像数据转化为对应的控制信号，并将该多个控制信号发送给与其相连接的数字微镜器件，数字微镜器件可以根据该多个控制信号，按照预定的输出时序，输出子图像的显示信号。
其中，子图像的显示信号包括子图像对应的多个子显示信号。也即，由全部的A像素点构成的子图像对应的子显示信号，由全部的B像素点构成的子图像对应的子显示信号，由全部的C像素点构成的子图像对应的子显示信号，以及由全部的D像素点构成的子图像对应的子显示信号。
举例来说，图8(a)、图8(b)、图8(c)、以及图8(d)为本申请实施例提供的子图像对应的子显示信号的图像示意图，按照预定的输出时序，先后输出由全部的A像素点构成的子图像对应的子显示信号，由全部的B像素点构成的子图像对应的子显示信号，由全部的C像素点构成的子图像对应的子显示信号，以及由全部的D像素点构成的子图像对应的子显示信号，即可获得如图8(a)、图8(b)、图8(c)、以及图8(d)所示的四个图像示意图。
接下来，合成棱镜可以对经多个透镜透射后的多个子图像的显示信号的光传输路径进行调节，合成待显示图像的显示信号。其中，待显示图像的显示信号包括待显示图像对应的多个子显示信号，待显示图像对应的每个子显示信号由多个数字微镜器件在同一时刻下输出的子图像对应的子显示信号合成获得。
图9(a)、图9(b)、图9(c)、以及图9(d)为本申请实施例提供的待显示图像的子显示信号的图像示意图，如图9(a)、图9(b)、图9(c)、以及图9(d)所示，若数字微镜器件为两个，则待显示图像对应的每个子显示信号，由该两个数字微镜器件在同一时刻下输出的子图像对应的子显示信号合成获得，也即由该两个数字微镜器件输出的由全部的A或B或C或D像素点构成的子图像对应的子显示信号合成获得，相应地，即可获得如图9(a)、图9(b)、图9(c)、以及图9(d)所示的图像示意图。
需要说明的是，图10为本申请实施例提供的视觉呈现的待显示图像的示意图，虽然用于合成待显示图像的显示信号的子显示信号是按照预定的输出时序进行输出的，获得的待显示图像也会按照预定的时序进行显示，但由于整个输出过程是连续且快速的，由于人眼具有视觉暂留，因此最终视觉呈现出的待显示图像为包含A、B、C、D全部像素点的叠加 显示的待显示图像，如图10所示。
通过上述方式，进一步提高了投影显示的分辨率。
在上述实施例的基础上，由于进行分帧处理后，在子图像对应的多帧图像中，每帧图像的像素点的位置有所不同，举例来说，将子图像中每个像素点分为A、B、C、D四个子像素点时，每个子像素点的位置有所不同，如图7所示，A像素点的位置在左上角，B像素点的位置在右上角、C像素点的位置在右下角、D像素点的位置在左下角。
因此，分别由全部的A、B、C、D像素点构成的子图像之间的相对位置也会有所不同。例如，由全部的B像素点构成的子图像，相对于由全部的A像素点构成的子图像，在其右侧的位置，由全部的C像素点构成的子图像，相对于由全部的B像素点构成的子图像，在其下方的位置。相应地，合成获得的各待显示图像之间的相对位置也会有所不同。因此，为了保证每个待显示图像的全部像素点均能被投影显示，需要对应合成棱镜设置振镜模块。振镜模块可以基于每帧待显示图像的显示信号的输出时序，执行对应的角度旋转，以使子图像对应的多个子显示信号，经由振镜模块透射输出子图像对应的经过抖动处理的多个子显示信号。
在一个示例中，振镜模块可以为4-way振镜，该4-way振镜可以通过旋转，使每帧待显示图像产生左右、上下的相对位置的变化，也即抖动处理。
图11为本申请实施例提供的振镜模块抖动处理的示意图，如图11所示，若每帧待显示图像的显示信号的输出时序为，先后输出由全部的A像素点构成的待显示图像的子显示信号，由全部的B像素点构成的待显示图像的子显示信号，由全部的C像素点构成的待显示图像的子显示信号，以及由全部的D像素点构成的待显示图像的子显示信号，则振镜模块18可以根据该输出时序，在输出由全部的A像素点构成的子图像对应的子显示信号之后，执行对应的角度旋转，使由全部的B像素点构成的子图像对应的子显示信号，经过抖动处理，透射输出，位置相对于由全部的A像素点构成的子图像对应的子显示信号向右变化的子显示信号。
相应地，在输出由全部的B像素点构成的子图像对应的子显示信号之后，振镜模块18执行对应的角度旋转，使由全部的C像素点构成的子图像对应的子显示信号，经过抖动处理，透射输出，位置相对于由全部的B像素点构成的子图像对应的子显示信号向下变化的子显示信号。相应地，对由全部的D像素点构成的子图像对应的子显示信号，也进行相应的抖动处理。需要说明的是，针对不同子显示信号，其输出方向可以基于子像素之间的相对位置确定，例如，上述举例的B子像素相对位于A子像素的右侧，故做抖动处理时，将B子像素对应的子显示信号向右平移。
本实施例提供的投影显示设备，采用分帧模块对子图像进行分帧处理，进一步提高了投影显示的分辨率，此外，采用振镜模块对子图像的子显示信号进行抖动处理，从而可以 保证每个待显示图像的全部像素点均能被投影显示，保证了图像的完整且显示正常。
