20090174698PRE-CHARGE SYSTEM FOR ON GLASS LCD DRIVING CIRCUIT - A driving circuit and a method of driving a liquid crystal display having an array of liquid crystal cells connected to a common line, a plurality of gate lines and a plurality of signal lines, each gate line being arranged to selectively enable a respective set of the liquid crystal cells such that signal lines connected to respective liquid crystal cells of a set can be used to charge respective liquid crystal cells of that set when that set is enabled by the respective gate line. The common line is driven with a common signal having selectively one of a first level and a second level. The gate lines are driven so as to selectively enable the respective sets of liquid crystal cells. Liquid crystal cells are charged with video signal levels varying between a minimum level and a maximum level wherein, when the common signal has the first level, the minimum level is the first level and the maximum level is the second level and, when the common signal has the second level, the minimum level is the second level and the maximum level is the first level. At least some of the signal lines are selectively driven with the maximum level and the voltage on the at least some of the signal lines is monitored such that driving of the at least some of the signal lines with the maximum level ceases when the monitored voltage reaches a predetermined target value intermediate the minimum level and the maximum level. A control circuit is configured to pre-charge liquid crystal cells prior to charging those liquid crystal cells according to the video signal levels by driving those liquid crystal cells with the maximum level until the monitored voltage reaches the predetermined target value.07-09-2009
