Description
This case is to be on March 28th, 2007 applying date, and application number is 200710091582.9, and denomination of invention is divided an application for " driving method of field order type liquid crystal display device " application for a patent for invention.
Technical field
The invention relates to a kind of driving method of display, particularly have the driving method of the field order type liquid crystal display device of interleaved type scanning relevant for a kind of driving.
Background technology
Along with making rapid progress of science and technology, the science and technology universalness, all desktop computers, notebook computer, mobile phone, personal digital assistant, LCD TV and digital still camera etc. all must will use LCD, hence one can see that, and LCD has just like become an indispensable ring among the human lives.That LCD has is thin, light, low power consumption, radiationless pollution and can be compatible etc. with the manufacture of semiconductor technology characteristic.For continuing to keep the competitive edge of LCD, LCD is developed field sequence type (field-sequential) technology, this technology is improved the bottleneck of conventional liquid crystal really, as elevator system colour gamut and saturation degree, reduction material cost etc., especially more can increase substantially the electric light conversion usefulness of about 40% panel system.
Field order type liquid crystal display device now adopts the type of drive of data line and sweep trace in the active-matrix collocation LCD mostly, wherein the most extensive utilization for to utilize thin-film transistor circuit to reach the switch motion of each pixel.Because the action such as the same switch of thin film transistor (TFT), the effect of liquid crystal cell such as same electric capacity, the On/Off action by thin film transistor (TFT) is to write/to keep action to the stored magnitude of voltage of liquid crystal cell.When input one scan signal, thin film transistor (TFT) presents the conduction impedance (resistance-on as opening; RON), because of conduction impedance has very low resistance value, data-signal to display can write liquid crystal cell to be sent on each pixel via described thin film transistor (TFT).Otherwise, when described thin film transistor (TFT) presents not conduction impedance (resistance-off as closed condition; ROFF) time,, can prevent that data-signal from leaking and this data-signal is remained on each pixel from liquid crystal cell, make each pixel have the action of memory, and wait for next time and driving because of conduction impedance not has very high resistance value.The gate electrode of same row is connected to the sweep trace in the LCD in the thin-film transistor circuit, is connected to data line in the LCD with the source electrode of delegation, no matter therefore be that sweep trace or data line are only respectively by single driver drives.
In other words, be that sweep trace in the LCD is by a gate driver drive, described these data lines are by the one source pole driver drives, because be subject to the driving force of single driver, the direction of transfer of described these data-signals and the direction of scanning of sweep trace only can be single direction.The scan pattern of the field order type liquid crystal display device of prior art is P-SCAN from top to bottom, after data line writes data-signal, liquid crystal cell according to signal that sweep trace provided to determine whether data signal produces brightness and color to pixel, wherein because of being subjected to the influence of the reaction velocity of liquid crystal cell own, cause pixel to manifest with having between the sweep velocity mistiming, this time is worse than the bottom especially severe of LCD.In other words, when promptly producing brightness and color when the zone on the LCD top end of scan and on pixel, the preceding a collection of data-signal that is positioned at the LCD bottom also is not transformed into the position that will produce brightness and color, and the zone that therefore is positioned at the LCD bottom can produce tangible colour mixture (color mixed) phenomenon.Therefore, a kind of effective desalination of current needs is because of the method for the not enough mixed color phenomenon that causes of reaction velocity.
Summary of the invention
Purpose of the present invention is for a kind of driving method of field order type liquid crystal display device is provided, in the scanning process of field order type liquid crystal display device, can be by the interleaved type scanning mode with desalination because of the not enough mixed color phenomenon that is caused of reaction velocity.
Driving method according to disclosed field order type liquid crystal display device, in order to drive liquid crystal panel, this liquid crystal panel has complex data line and plural sweep trace, described method comprises the following step: drive first grid driver and second grid driver, to transmit plural signal respectively to described these sweep traces; And according to described these signals, drive first source electrode driver and second source electrode driver, transmitting the complex data signal respectively to described these data lines, in wherein said these data lines in the direction of transfer of the data-signal of odd data line and described these data lines the direction of transfer of the data-signal of even data line be reverse direction parallel to each other or the alternate directions that crosses one another.
The present invention by controlling described these data lines respectively transmission direction and the direction of scanning of sweep trace, can effectively reach the effect that desalination results from the mixed color phenomenon in liquid crystal panel four side zone.
