[embodiment]
Fig. 1 has illustrated the picture element array structure of one embodiment of the invention.Please with reference to Fig. 1, picture element array structure 100 comprises many first sweep traces 112, many second sweep traces 114, many first data lines 122, many second data lines 124 and a plurality of dot structure 130.Each first sweep trace 112 is walked crosswise (column) direction R along one and is extended, and second sweep trace, 114 parallel first sweep traces 112, and first sweep trace 112 and second sweep trace 114 are alternately arranged.Each first data line 122 extends along perpendicular row (row) direction C, and second data line, 124 parallel first data lines 122, and first data line 122 and second data line 124 are alternately arranged.130 ranks of dot structure are arranged between these staggered sweep traces and data line, and n walks crosswise dot structure 130 between n bar first sweep trace 112 and n bar second sweep trace 114, and wherein n is a positive integer.That is to say that the same dot structure of walking crosswise 130 is to be driven by two sweep traces, and picture element array structure 100 is a kind of topological design of dual scanning line.
Each dot structure 130 comprises one first driving component 132, one second driving component 134 and a pixel electrode 136.First driving component 132 side by side is connected pixel electrode 136 with second driving component 134.Each dot structure 130, the first driving components 132 are electrically connected corresponding first scanning line 112.One of them is electrically connected first driving component 132 first data line 122 and second data line 124.Second driving component 134 is electrically connected corresponding second sweep trace 114, and wherein another of first data line 122 and second data line 124 is electrically connected second driving component 134.In other words, first driving component 132 in the same dot structure 130 must be connected in different sweep traces with second driving component 134.With present embodiment, first driving component 132 of the perpendicular row of 2n-1 (the perpendicular row of odd number) dot structure 130 all is electrically connected first sweep trace 112, and first driving component 132 of the perpendicular row of 2n (the perpendicular row of even number) dot structure 130 is electrically connected second sweep trace 114.
In addition, in order to drive these dot structures 130, picture element array structure 100 also includes first grid driver 110a, second grid driver 110b, the first source electrode driver 120a and the second source electrode driver 120b.With present embodiment; First grid driver 110a and second grid driver 110b lay respectively at dot structure 130 in the both sides of walking crosswise on the direction R, and first grid driver 110a and second grid driver 110b are respectively in order to scan first sweep trace 112 and second sweep trace 114.The first source electrode driver 120a and the second source electrode driver 120b then lay respectively at the both sides of dot structure 130 on perpendicular column direction C, and the first source electrode driver 120a and the second source electrode driver 120b are respectively in order to input signal to the first data line 122 and second data line 124.
What deserves to be mentioned is that the setting of the first source electrode driver 120a is in order to export the needed picture signal of display image.Therefore, the GTG that shown of each dot structure 130 for example all mainly decides according to the picture signal of first source electrode driver 120a output.But, picture element array structure 100 has the design of double scanning line.Under identical frame rate, the time that each dot structure 130 can be recharged in the picture element array structure 100 shortens (generally speaking, the duration of charging of dual scanning line design can shorten half the approximately) and causes display quality not good than the design of single scanning line.So in the present embodiment, the second source electrode driver 120b makes the not good situation of display quality in order to export a difference complement signal to improve the duration of charging deficiency.
Explanation for ease, in all diagrams, the sign of G1～G5 is expressed as among the figure the 1st first sweep trace 112 respectively to the 5th first sweep trace 112.In addition, G1-1～G4-1 is expressed as among Fig. 1 the 1st second sweep trace 114 respectively to the 4th second sweep trace 114.That is to say that the Gi in the diagram representes i bar first sweep trace 112, and Gi-1 all representes i bar second sweep trace 114.In addition, the Di in the diagram representes i bar first data line 122, and Di-1 all representes i bar second data line 124.
In detail, Fig. 2 A and Fig. 2 B have illustrated the scanning step sequential chart of the picture element array structure of one embodiment of the invention at a m frame time.Please be simultaneously with reference to Fig. 1,2A and 2B; Picture element array structure 100 can adopt following manner to drive: in a m frame time; First step F1 is shown in Fig. 2 A, in regular turn through first sweep trace 112 (for example being denoted as the sweep trace of G1, G2...Gi) transmission one scan signal.Simultaneously, by first data line, 122 images signals and by second data line, 124 transmission difference complement signals.That is to say that among the first step F1 of m frame time, first grid driver 110a can carry out scanning motion, simultaneously, the first source electrode driver 120a is with all first data lines 122 that are transferred to of picture signal correspondence.And the second source electrode driver 120b will differ from all second data lines 124 that are transferred to of complement signal correspondence.At this moment, the dot structure 130 of the perpendicular row of 2n-1 (the perpendicular row of odd number) all is transfused to picture signal, and the dot structure 130 of the perpendicular row of 2n (the perpendicular row of even number) all is transfused to poor complement signal.
Then; Second step F 2 in the m frame time; Shown in Fig. 2 B; Transmit another sweep signal through second sweep trace 114 (for example being denoted as the sweep trace of G1-1, G2-1...Gi-1) in regular turn, and simultaneously by first data line, 122 images signals and by second data line, 124 transmission difference complement signals.That is to say that in second step F 2 in the m frame time, second grid driver 110b can carry out scanning motion, simultaneously, the first source electrode driver 120a equally with picture signal corresponding be transferred to all first data lines 122.And the second source electrode driver 120b will differ from all second data lines 124 that are transferred to of complement signal correspondence too.At this moment, the dot structure 130 of the perpendicular row of 2n (the perpendicular row of even number) all is transfused to picture signal, and the dot structure 130 of the perpendicular row of 2n-1 (the perpendicular row of odd number) all is transfused to poor complement signal.That is to say that Fig. 2 A and the represented driving method of Fig. 2 B can be described as the driving method of a kind of hurdle counter-rotating (column inversion).
Under such type of drive, all dot structures 130 can in turn be transfused to picture signal and difference complement signal in first and second step F 1 of m frame time, F2.When dot structure 130 can't picture signal intactly be write because of the duration of charging is not enough fashionable, the display voltage that the poor complement signal among next step F1, the F2 can compensation pixel structure 130.Therefore, under same frame rate, the demonstration GTG that dot structure 130 is appeared will be approaching even consistent with preset state, and help to promote display quality.
Certainly, one of ordinary skill in the art will readily recognize that picture element array structure of the present invention is not limited to the layout type that Fig. 1 illustrates.For instance, as long as first driving component of a part connects first sweep trace, first driving component of another part connects the design that second sweep trace just can meet dual scanning line in several first driving components of same row dot structure.That is to say that several first driving components of same row dot structure do not need alternately to connect first sweep trace and second sweep trace.Therefore, a kind of embodiment does not need alternately to connect first sweep trace and second sweep trace with several first driving components of dot structure that same row are described state is below proposed.But, following embodiment is merely schematic explanation, is not in order to limit layout type of the present invention.
Fig. 3 has illustrated the picture element array structure of another embodiment of the present invention.Please with reference to Fig. 3, the topological design of picture element array structure 200 is different from picture element array structure 100, but both employed assemblies are all identical, so these identical assemblies are all with identical symbology.In addition, in order to simplify drawing, will no longer illustrate gate drivers and source electrode driver in the present embodiment.That is to say that gate drivers among Fig. 1 (110a, 110b) and source electrode driver (120a, 120b) in fact also can be disposed in the picture element array structure 200 of Fig. 3.
Particularly; The layout type of picture element array structure 200 is to make the perpendicular row of 4n-3 be electrically connected first sweep trace 112 with first driving component 132 of the perpendicular row dot structure 130 of 4n, and the perpendicular row of 4n-1 are electrically connected second sweep trace 114 with first driving component 132 of the perpendicular row dot structure 130 of 4n-2.That is to say that under such layout type, same first driving component of walking crosswise 132 is two and is connected to first sweep trace 112, next two are connected to second sweep trace 114, and two that follow are connected to the first sweep trace 112... again by that analogy again.In addition, first driving component 132 in each dot structure 130 and 134 of second driving components equally are one and are connected to first sweep trace 112 and another is connected to second sweep trace 114.That is to say that in the same dot structure 130, first driving component 132 can be connected to different sweep traces with second driving component 134.
In the present embodiment; The driving component that has no is arranged at first sweep trace 112 and 2n-1 bar (odd number bar) second data line 124 intersects part, and has no driving component to be arranged at second sweep trace 114 and 2n bar (even number bar) second data line 124 crossing parts.So when scanning first sweep trace 112, second data line 124 of 2n-1 bar (odd number bar) need not transmit any signal, and when scanning second sweep trace 114, second data line 124 of 2n bar (even number bar) need not transmit any signal.Therefore, the type of drive of picture element array structure 200 is different with aforesaid driving method.
For example, Fig. 4 A and Fig. 4 B have illustrated the scanning step sequential chart of the picture element array structure of another embodiment of the present invention at a m frame time.Please be simultaneously with reference to Fig. 3, Fig. 4 A and Fig. 4 B; In the first step F1 of m frame time; The driving method of present embodiment for example is in regular turn through scanning first sweep trace 112 transmission one scan signals; And simultaneously by first data line, 122 images signals and by second data line, the 124 images signals of n bar, and by second data line, 124 transmission outputs, the one difference complement signal of n+1 bar.At this, when the n bar was the even number bar, the n+1 bar was the odd number bar, and the n bar is when being the odd number bar, and the n+1 bar is the even number bar.
Then, in second step F 2 of m frame time, in regular turn through second sweep trace, 114 another sweep signals of transmission.Simultaneously, first data line 122 transmission one picture signals and by second data line, 124 transmission, one picture signal of n+1 bar, and by second data line, 124 transmission outputs, the one difference complement signal of n bar.In other words, the driving method of present embodiment is that first sweep trace 112 is scanned at the first step F1 of m frame time, and second sweep trace 114 is scanned in second step F 2 of m frame time.In addition, in the first step F1 of m frame time, the difference complement signal is only by 124 transmission of n bar second data line, and the difference complement signal is only by 124 transmission of n+1 bar second data line in second step F 2 of m frame time.
Under such type of drive, the scanning motion each time can make same second two second set driving components 134 of data line 124 both sides open simultaneously.Therefore, the dot structure 130 that is connected in same second data line 124 both sides can be transfused to poor complement signal simultaneously so that the display quality of picture element array structure 200 obtains to promote.
Certainly, picture element array structure 200 can also drive according to other mode.Fig. 5 A and Fig. 5 B have illustrated the scanning step sequential chart of the picture element array structure of another embodiment of the present invention at a m frame time.Please be simultaneously with reference to Fig. 3, Fig. 5 A and Fig. 5 B, the type of drive difference of the driving method of present embodiment and Fig. 4 A, 4B is the scan mode of sweep trace.In detail; In the present embodiment, when the first step F1 of m frame time, in a m frame; Through article one sweep trace 112 transmission one scan signals and in regular turn through 2N bar and first and second sweep trace 112,114 transmission one scan signals of 2N+1 bar, wherein N is an even number in regular turn; And when second step F 2 of m frame time, in regular turn through first and second sweep trace 112,114 transmission sweep signals of 2M bar and 2M+1 bar, wherein M is an odd number.
In addition, the driving method of present embodiment also comprises makes first data line, 122 transmission, one picture signal, and second data line 124 is alternate transmission one picture signal and a difference complement signal in two steps then.Thus, the dot structure 130 with delegation will alternately obtain the difference complement signal in different steps.So such driving method can be called the driving method of a kind of some counter-rotating (dot inversion).
The layout type collocation Fig. 4 A of Fig. 3 and the driving method of 4B or Fig. 5 A and 5B can make picture element array structure 200 under the prerequisite that does not change frame rate, improve the efficient that dot structure 130 is written into picture signal.Therefore, even the duration of charging of first driving component 132 is very short, each pixel electrode 136 equally can be written into enough voltage to present preset GTG value.In other words, though picture element array structure 200 has the design of dual scanning line, still can have good signal and write efficient and present desirable display quality.
In sum, the present invention under the basis of dual scanning line pixel array structure extra be provided with second data line and second driving component with the transmission bucking voltage to each dot structure.Therefore, under high frame rate,, still can reach desirable charge volume though the duration of charging of each dot structure is limited.That is to say that picture element array structure of the present invention can be promoted the display quality of dual scanning line product.
Though embodiments of the invention have disclosed as above; Right its is not in order to limit the present invention; Any those skilled in the art are not breaking away from the spirit and scope of the present invention, when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
