Description of drawings
The reader will become apparent various aspects of the present invention after the reference accompanying drawing has been read the specific embodiment of the present invention.Wherein,
Figure 1A illustrates the polarity of voltage distribution figure that each pixel under the prior art mid point inversion driving mode loads;
Figure 1B illustrates the polarity of voltage distribution figure that each pixel under row counter-rotating (2V counter-rotating) type of drive loads in the prior art; And
Fig. 2 illustrates the polarity of voltage distribution figure that each pixel loads in the picture element array structure of the present invention.
Embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention is described in detail.
At first, briefly introduce relative theory about Thin Film Transistor-LCD.Known as us, when not powering up between the upper and lower base plate of liquid crystal panel, liquid crystal is arranged according to 90 degree directions, and light revolved along the liquid crystal molecule direction and turn 90 degrees propagation this moment, because polaroid also is vertical 90 degree direction settings down, light just in time can pass through.When powering up, because the orientation of liquid crystal molecule changes, light can not pass through, and is shown as blank screen.Usually, the tft liquid crystal screen is divided into two glass substrates up and down, the below is a tft array substrate, usually along continuous straight runs is provided with grid (being also referred to as scan electrode), source electrode (being also referred to as show electrode) vertically is set, place, point of crossing at grid and source electrode is provided with thin film transistor (TFT), and its grid and source electrode correspond respectively to scan electrode and show electrode.
For the mode of memory capacitance Cs, when the voltage of show electrode is higher than this common electrode voltage, be called positive polarity with the common electrode voltage cabling; And when the voltage of show electrode is lower than this common electrode voltage, be called negative polarity.By reversal of poles, can effectively eliminate the flip-flop in the liquid crystal, prevent that liquid crystal from being decomposed by direct current, the ion that suppresses in the glass migrates to liquid crystal and prevents that scintillation from appearring in liquid crystal panel.
Figure 1A illustrates the polarity of voltage distribution figure that each pixel under the prior art mid point inversion driving mode loads; And Figure 1B illustrates the polarity of voltage distribution figure that each pixel under row counter-rotating (2V counter-rotating) type of drive loads in the prior art.In Figure 1A and 1B, each the sub-pixel size size in the picture element array structure is all identical, and is ordered in the effective coverage of liquid crystal panel up and down alignedly.According to corresponding test result, when adjusting Vcom under the situation of image flicker, the size of sub-pixel is big more, and the area in winking zone is also big more, and then flicker level also becomes more and more serious.
Because Figure 1A adopts an inversion driving mode, and Figure 1B adopts capable inversion driving mode, thereby the flicker level under Figure 1B type of drive is understood even worse compared to Figure 1A, because during the row counter-rotating, the region area of identical polar increases (shown in the frame of broken lines among Figure 1B), very easily causes image flicker and the imaging of rhombus network occurs.
In order effectively to address this problem, the present invention proposes a kind of improved picture element array structure.Fig. 2 illustrates the polarity of voltage distribution figure that each pixel loads in the picture element array structure of the present invention.As previously mentioned, this picture element array structure comprises a plurality of pixels, and each pixel has Red sub-pixel, Green sub-pixel, Blue sub-pixel (being the RGB three primary colors), with reference to Fig. 2, the size of at least a portion Red sub-pixel in this structure, Green sub-pixel and Blue sub-pixel has nothing in common with each other, and staggered being ordered in the effective coverage of liquid crystal panel.
Specifically, shown in the frame of broken lines among Fig. 2, the sub-pixel in this zone is not that image pattern 1A or Figure 1B are such, is ordered in the effective coverage up and down alignedly, but staggered regularly arranged.For example, neighbouring sub-pixel may be not to align one by one at vertical direction.In addition, in conjunction with Figure 1B and Fig. 2, in identical region area, the same polarity zone of Figure 1B accounts for 4 grids of this area, and the same polarity zone of Fig. 2 only accounts for 2.5 grids of this area, that is to say, adopt staggered regularly arranged sub-pixel setting, can reduce the region area of identical polar effectively, and then improve the film flicker phenomenon, improve visual effect.
In addition, from Fig. 2, it can also be seen that in delegation or same row, to have a pair of adjacent opposite polarity that sub-pixel loaded at least.And, when the different type of drive of the collocation of a plurality of sub-pixels in this structure, can dwindle the area in same polarity zone.
In one embodiment, the area size of staggered regularly arranged sub-pixel be the normal-sub pixel area (as the size of Fig. 2 medium square demonstration) 1/2.Yet, those of ordinary skill in the art is to be understood that, these staggered regularly arranged sub-pixels can also form other ratio of normal-sub pixel, and have more than half that is confined to its size, and the different sizes between the dimensions of all these sub-pixels and a plurality of sub-pixel is included in the scope of the present invention.
In addition, for the sub-pixel that size has been dwindled, a kind of electric connection mode is to be, these staggered two regularly arranged adjacent same polarity sub-pixels vertically are tapped into a data line up and down.And another kind of electric connection mode is, these staggered two regularly arranged adjacent same polarity sub-pixels are controlled the switch and the charging sequential of thin film transistor (TFT) separately by two gate lines respectively.
Adopt picture element array structure of the present invention, the parton Pixel Dimensions of the effective coverage of liquid crystal panel is reduced, and the staggered pel array that is ordered in, meanwhile, different pixel drive modes or the polarity of arranging in pairs or groups distributes, thereby can dwindle the area in identical polar zone, use problems such as improving film flicker and the imaging of rhombus network, visual effect is better.
Above, describe the specific embodiment of the present invention with reference to the accompanying drawings.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also do various changes and replacement to the specific embodiment of the present invention.These changes and replace all drop in claims of the present invention institute restricted portion.
