Design of LCD Multi Line Selection Driver IC

MLS driving mode could increase the display of passive dr iving by virtue of low power consuming, high contrast, rapid responding time, le ss crosstalk, low manufacturing cost and wide operating temperature range. Taking Hadmoard matrix as basic orthodoxy func tion, system structure of 4 line MLS dri ving integrated circuit was given out. T he key part of segment driving integrate d circuit-encoding transfer module was d esigned with dynamic decoding array stru cture. The simulation results obtained b y UMC 0.6 μm process show that the delay time in 5V was 11ns, the max. operating frequency was over 20 MHz and the functi onal and parametric performance could me et the demand of practical design and ap plication.
