Description

一种手持设备及与电视同步显示的方法 技术领域
本发明涉及一种手持设备及其显示实现的方法，尤其涉及一种手持设备及与电视同步显示的方法。
 背景技术
现有手持设备的显示分辨率大部分都远远低于标清的标准，更难达到高清的标准，而用户经常会将手持设备的数据传输到电视屏幕上播放，以获得更好的感官体验。而将一个低分辨率的数据传输到高分辨率的显示设备去显示时，必然会产生拉伸、变形等不良的视觉效果。
目前，市场上已有的手持设备与电视屏幕同步显示的技术都是通过硬件的方式来实现。它们通过多个数据通路的方式，将手持设备输出的数据转换为两路或两路以上输出信号分别输出到手持设备和电视上实现同步显示。其数据通路实现的方式包括两种：模拟信号输出方式和数字信号的输出方式。前者较后者在硬件成本上要大大降低，但是其在电视屏幕上的显示效果比较差，而后者的成本将大幅提高，增加了用户的使用成本。同时这两者都有一个严重的缺陷，由于分辨率不同，低分辨率的手持设备输出的显示数据输出到电视屏幕后会被拉伸以配合电视的大屏幕显示，而这种显示方式分辨率并未提高，仍然保持手持设备原有的分辨率，这大大降低了用户了使用的体验效果。

并且在所述步骤301之前还包括：所述手持设备与电视屏幕相连接，所述手持设备通过HDMI线与电视连接，以获取电视的分辨率信息，所述手持设备选择双屏显示模式，所述手持设备获取所述电视屏幕的标准显示分辨率信息，并按照所述标准显示分辨率信息初始化所述手持设备。
手持设备与电视屏幕相连接并进入双屏显示模式，手持设备准备向电视屏幕传输的相关显示数据，同时手持设备开始初始化流程，即所述手持设备将所述输出显示数据的EGL数据库销毁并关闭帧缓冲驱动204。然后再次初始化所述EGL数据库，按照所述电视屏幕的标准显示分辨率初始化所述EGL数据库并打开所述帧缓冲驱动204，得到标准显示分辨率的输出显示数据，并在所述电视屏幕上显示；同步的所述帧缓冲驱动204将所述输出显示数据传输到模数转换芯片203，所述模数转化模块203将所述输出显示数据压缩为适合手持设备显示器件分辨率的手持显示数据，并在所述手持设备显示器件上同步显示。保证了在手持设备与电视屏幕上清晰的同步显示的同时，提高了电视屏幕上播放的清晰度，降低了手持设备的制造成本。
应当理解的是，上述针对较佳实施例的描述较为详细，并不能因此而认为是对本发明专利保护范围的限制，本领域的普通技术人员在本发明的启示下，在不脱离本发明权利要求所保护的范围情况下，还可以做出替换、简单组合等多种变形，这些均落入本发明的保护范围之内，本发明的请求保护范围应以所附权利要求为准。
