显示器用IC

对全彩色、更高分辨率显示技术的需求空前高涨,尤其是家庭娱乐和家庭影院产品,包括投影电视以及LCD TV。在投影领域,高分辨率LCD微显示技术实现了大面积显示配置,例如具有清晰的、高分辨率、全彩色图像、高性价比的背投电视(RPTV)以及家庭影院投影产品。对于LCD TV而言,改进的电源、γ和Vcom解决方案支持全动态视频、改善的图像质量以及较低的成本。为了满足实现新型消费显示产品面临的苛刻成本与性能目标需求,ADI公司开发出DecDriver®系列LCD微显示驱动器产品。DecDriver®系列驱动器通过降低较高分辨率消费类应用的LCD投影仪的驱动电路成本,实现了高质量的LCD数据投影系统。在LCD TV领域,显示面板尺寸的快速增长使得面板制造商在电源、γ基准源以及Vcom驱动IC方面面临着挑战。ADI公司已经开发出满足这些需求、为不同面板尺寸和性能而优化的多种解决方案。
