Description
Technical field
The present invention about a kind of image element driving method, especially in regard to a kind of image element driving method of liquid crystal indicator.
Background technology
Liquid crystal display (LiquidCrystalDisplay, LCD) device is low with its power consumption, thermal value is few, lightweight and non-radiation type etc. advantage, be used in electronic product miscellaneous, and little by little replace traditional cathode-ray tube (CRT) (CathodeRayTube, CRT) display device.
Generally speaking, liquid crystal indicator mainly comprises a display panels (LCDPanel) and a backlight module (BacklightModule).Wherein, display panels mainly has a thin film transistor base plate, a colored optical filtering substrates and is located in liquid crystal layer between two substrates, and two substrates and liquid crystal layer form the pixel that several array is arranged.The uniform light of one light source can be distributed to display panels by backlight module, and forms a pattern via each pixel display color.But, because the voltage between each pixel-penetrance curve can watch the angle (such as just seeing and side is seen) of display panels and different along with user, therefore the phenomenon of colour cast will be had to produce when different visual angles viewing display panel.
For improving color offset phenomenon, existing multiple known technology is developed, wherein most technical characteristic is that single pixel is divided into a clear zone and a dark space again, different through voltage-penetrance curve that twoth district are just being seen and side is seen thus, and there is the effect mutually compensated, to reach the object of low colour cast (LowColorShift, LCS).
In low colour cast technology, each pixel additionally has a building-out capacitor, in one first image duration (frametime), when next sweep trace activation of this pixel, the data-signal (being called the first data-signal) of this pixel is passed to building-out capacitor.Then, in one second image duration, when data line writes data-signal (being called the second data-signal) again to this pixel, the first data-signal and the second data-signal can reach charge balance and form dark space.Certainly, in this situation, for same pixel, the data-signal of its write is required to be positive polarity, negative polarity, positive polarity ... in sequential, and the arrangement of alternate polarisation just can reach the effect of charge balance.
But above-mentioned low colour cast technology can have problems when being applied to 3D display.In 3D display technique, same pixel needs sequentially to write right eye viewing data, left eye viewing data, right eye viewing data ... in the sequential of image duration, and right eye and left eye watch the arrangement of data interlace, form 3D image with activation beholder.And 3D technology is when coordinating low colour cast technology, do not have 3D display effect good and produce two kinds of situations such as image residue.
In the first case, the polarity of the data-signal that such as same pixel writes in sequential is+(right eye 1) ,+(left eye 1) ,-(right eye 2) ,-(left eye 2) ,+(right eye 3) ,+(left eye 3) ,-(right eye 4) ,-(left eye 4) ... arrangement, wherein+representing positive polarity ,-representing negative polarity.For the sequential corresponding to right eye 3, the data-signal (+polarity) of right eye 3 and the data-signal of left eye 2 (-polarity) form charge balance and produce dark space effect.For the sequential of left eye 3, the data-signal of left eye 3 and the data-signal of right eye 3 form charge balance, but left eye 3 is all positive polarity with the data-signal of right eye 3.As a result, for same pixel, the effect of its low colour cast is different, causes 3D display effect not good.
In the second situation, the polarity of the data-signal that such as same pixel writes in sequential is+(right eye 1) ,-(left eye 1) ,+(right eye 2) ,-(left eye 2) ,+(right eye 3) ,-(left eye 3) ,+(right eye 4) ,-(left eye 4) ... arrangement.But right eye can be caused in this kind of situation to watch data and be all positive polarity, left eye viewing data are all negative polarity, make to there is an internal electric field in liquid crystal cells, thus the phenomenon such as electron-collection so that image residue (imagesticking) occurs.
Therefore, how to improve the image element driving method of liquid crystal indicator, make low colour cast technology can more suitably be applied to 3D display technique, and then promote display usefulness, real is one of current important topic.
