Description
本文涉及但不限于投影显示技术，尤指一种实现多屏显示的方法及装置。
投影仪是日常会议和多媒体资源分享的主要工具。常用的投影仪一般包含客户端显示屏和投影显示屏；其中，客户端显示屏一般是用户执行投影操作时的显示窗口，投影显示屏通过投影仪的投影装置放大显示与客户端显示屏相同的文件内容。当用户需要进行其他文件内容的显示时，需要客户端显示屏结束显示或暂停当前显示的文件内容的操作的情况下，通过客户端显示屏打开新的需要显示的文件内容的路径，实现新的文件内容的显示。
上述投影显示的方法，投影仪的客户端显示屏和投影显示屏上显示的文件内容相同；在查看其它文件内容时，需要通过客户端显示屏进行显示文件内容切换的操作，客户端显示屏和投影显示屏根据切换的文件内容同时显示新的文件内容；用户在投影显示屏显示文件内容过程中，如果需要从投影仪上获取其他需要的文件内容，用户对客户端显示屏的操作会造成投影显示屏同时切换，影响了投影仪的工作效率和用户体验；另外，用户在投影仪上执行当前投影显示屏的投影时，用户无法在客户端显示屏上查看其他文件内容，也无法提前准备投影显示屏下一次显示的内容，切换投影的文件内容需要等到当前投影结束或中断当前的投影才可以进行，同样影响投影仪的工作效率和用户体验。
