Abstract

The invention discloses a driving method and device of a liquid crystal display (LCD) panel and a time controller of the LCD panel, aiming to eliminate image blur while not changing the commercial standard driver, in particular eliminate sample and hold artifact. The time controller of the invention is used to control a plurality of source drivers and gate drivers on a LCD panel module. The time controller of the invention contains a data processing module and a control signal generating module, wherein the data processing module is used to generate a data signal containing image data and black data; and the control signal generating module is used to generate a plurality of initial level signals, a first gate activating signal and a second gate activating signal, wherein the initial level signal series is used to input the data signal in the source drivers, the first gate activating signal and the second gate activating signal correspond to different activating times, and the first gate activating signal and the second gate activating signal are selectively output to the gate drivers.

Description

technical field [0001] The present invention relates to a solution to motion image blur of a hold type display device, in particular to a method and device for driving a liquid crystal panel and a related time controller. Background technique [0002] For hold type display devices, such as active matrix liquid crystal displays (AMLCDs), motion image blur is a widely discussed issue. Causes of moving image blur include: slow liquid crystal response time, pixel capacitance changes, and so-called "sample and hold artifacts." [0003] According to the conventional technology, the former two can be solved by utilizing voltage overdrive (voltage overdrive) and other methods. However, the latter is relatively difficult to deal with because it is a combination of the sampling characteristics of these active matrix liquid crystal displays and the smooth motion tracking characteristics of the user's visual system, so it still widely exists in the liquid crystal displays on the market...
