摘要
目前已经相当普及的液晶(LCD)电视需要背光。当前主要采用LED背光,在该背光控制中用一个MCU控制LED驱动以产生背光。随着技术的发展,3D电视在市场占有率不断提升,在3D电视中,也需要一个MCU来发射3D眼镜同步信号。基于此,提出一种基于一颗高性能单片机MSP430G2553实现3D电视的背光扫描和3D眼镜同步信号控制方法,3D眼镜同步信号产生采用红外发射来产生,该设计方案具有低功耗、成本低、性能可靠的优点。
Liquid Crystal Display （LCD） TVS have become common. LCD display require backlight. At present LED backlighting is mainly used. In the backlight control used an MCU to control LED drive in order to produce backlight. Along with technology development, 3D TVS in the market share rising, it needs a MCU to send 3D glasses sync signal. Based on above, a new method which uses one high perform single chip MSP430G2553 implemented 3D TVS backlight scan and sent 3D glasses sync signal is pro- duced. It used infrared emission to generate 3D glasses sync signal. This design had low power,low cost,reliable performance advantages.
