Description
Technical field
The present invention is about a kind of liquid crystal indicator, particularly relevant for a kind of liquid crystal indicator of eliminating ghost, configuration time thin film transistor (TFT) (TFT) in pixel, the grid of this thin film transistor (TFT) connects last sweep trace, and the source electrode of this thin film transistor (TFT) connects adjacent data line, be beneficial to loss pixel institute stored charge, and effectively eliminate image residue.
Background technology
Along with the progress of optics science and technology with semiconductor technology, liquid crystal indicator has been widely used on the electronic product display device.Advantages such as LCD has that high image quality, volume are little, in light weight, low voltage drive, low consumpting power and applied range, it has replaced the mainstream technology that traditional cathode-ray tube (CRT) becomes display.
Generally speaking, liquid crystal indicator (LCD) comprises two substrates and has liquid crystal to be sealed in therebetween, pixel electrode and thin film transistor (TFT) (TFT) are set on the substrate, and are set on another substrate with respect to the common electrode that the color filter film and of each pixel electrode is shared on each pixel.Color filter film comprises red (R), green (G), blue (B) three kinds, and can be provided with a kind of filter coating in these three kinds of colors in each pixel.The mutual neighbour of red, green, blue color pixel establishes and constitutes a pixel together.
In addition, industry has had multi partition vertical orientation (the Multi-domainVertical Alignment of preferable viewing angle characteristic; MVA) formula LCD, this technology also is applied on the liquid crystal display television (LCD-TV), and technical characterictic is that it cuts apart a pixel is four subregions (4domain).The LCD of MVA technology manufacturing has advantages such as high contrast, wide viewing angle and large scale compatibility, but its LCD screen is in the comparison of forward sight and side-looking, can find still that side-looking produces to appear in one's mind in vain resembles (color washout), and response time is slower, and this will reduce the quality of image of MVA pattern.Reduce colour cast, the method for full blast can adopt octant (8 domain) technology to solve, and promptly pixel partitions number (doma ins) is increased to 8 numbers of partitions or more from 4 numbers of partitions.It can utilize capacitive coupling type (Capacitance Coupling type, C-C type), Double Data or double-gate type (T-T type) and common voltage swing (common voltageswinging, Com-swing) technology and produce 8 number of partitions pixels.Wherein therefore swing (Com-swing) Technology Need extra integrated circuit (ICs) and electronic package of Double Data or double-gate type (T-Ttype) and common voltage increased whole manufacturing cost.Though capacitive coupling type (CC-type) technology can not increase manufacturing cost, because its floating electrode from the electric capacity that is coupled can cause serious image residue.Shown in figure one left side, traditional capacitive coupling type (CC-type) pixel design, it is to utilize the mode of metal capacitance induction to make pixel be divided into two zones 60,61, wherein zone 60 signal is to utilize data-signal (for example 5 volts) directly to import and make Clc-1 electric capacity produce the voltage identical with data-signal, the signal in 1 zone 61 is to utilize Clc-2 capacitances in series Cx electric capacity in addition, the induction that sees through Cx electric capacity makes and becomes a ratio with Clc-2 by the capacitance Clc-1 in two districts (for example Clc-1 is 5 volts, Clc-2 is 3 volts), the result makes two zones 60,61 briliancy difference.In addition, figure one the right is the equivalent circuit diagram of capacitive coupling type (CC-type) pixel design.And the mode of this design can produce residual charge at the metal level of induction and cause serious image retention (image sticking).With reference to figure two, after (left side picture comprises zone 65 and zone 66) did and burn attached test under the gridiron pattern picture, picture (the right picture comprises zone 65 and zone 67) can't recover back normal pictures.That is the picture in the zone 67 still has GTG and can't recover back the normal pictures in zone 65.

SubAnd Clc
SubBe respectively storage capacitors and LC electric capacity in time district, Cx is a coupling capacitance, and Vmain is the voltage in primary area, and Isub is the charging current for inferior thin film transistor (TFT) (sub-TFT) 81.Therefore, by Cx and Isub in the simple modifications pixel design, Vsub can optimization resembles and need not increase the high price electronic package to reduce to appear in one's mind in vain.Blanket speech, additional renewal technology (ART) is at one thin film transistor (TFT) (sub-TFT) of pixel indoor design, gives an ac small signal in time pixel electrode place of floating, to prevent remaining electric charge accumulation.
By prior art as can be known, the additional renewal technology (ART) of the multi partition vertical alignment mode (AMVA mode) that strengthens, increase thin film transistor (TFT) (sub-TFT) one time, thin film transistor (TFT) (sub-TFT) the grid sweep trace connection of pixel therewith this time, the stored charge of time pixel electrode of floating can be through the data line dissipation of pixel thus, and wherein main thin film transistor (TFT) (main-FTT) and time thin film transistor (TFT) (sub-TFT) employed be identical sweep trace and data line.When opening, its grid,, so can increase the time of liquid crystal display so sub-pixel (sub-pixel) just can charge after needing earlier remaining electric charge to be removed synchronously with its store charge dissipation.
Therefore, the invention provides a kind of ghost that is better than known technology and suppress method and apparatus, it is the incomparable person of known technology, and can increase liquid crystal display usefulness effectively.
