液晶电视3D显示技术的探讨与设计

摘要

With the rapid development of 3D display technology and product line gradual y mature, 3D TV has replaced the 2D TV common become the primary choice of the consumers, in a variety of display systems, shutter type 3D liquid crystal display system with the stereo effect is prominent, picture high resolution LCD module, low cost advantages are widely recognized by the market.And drive 3D LCD TV backlight design, this paper mainly studies the shutter, including the control power supply design, software control and the LED light source of three parts, including design, hardware design including the booster module and constant current source design, software control comprises the backlight lamp current, duty cycle to control time sequence. 3D LED series and is adjusted each lamp brightness, delay and voltage to realize the control of the LED backlight scanning sequence.%随着3D显示技术的飞快发展和产品线的逐渐成熟，家用3D电视已经逐步取代普通的2D电视成为广大消费者的首要选择，在种类繁多的显示系统中，快门式3D液晶显示系统以其立体效果突出、画面分辨率高、液晶模组成本低等优势得到了市场的广泛认可。本文主要研究快门3D液晶电视背光源设计和驱动，包括电源设计、软件控制和LED光源的控制三大部分，其中硬件设计包括升压模块的设计和恒流源的设计，软件控制包含背光灯条电流、占空比以及时序的控制。3D LED串并联通过调节各个灯条的亮度、延时以及电压大小实现对LED背光扫描时序的控制。
