Seeing also Fig. 1, is a kind of electrical block diagram of prior art display panels.This display panels 1 comprises the m bar pixel electrode 13 of at interval sweep trace 11, n bar space and the data line 12 vertical with this sweep trace 11, a plurality of m of being * n (m>1, n>1) arranged and a plurality of and this pixel electrode 13 thin film transistor (TFT) 14 one to one that is parallel to each other.The drain electrode of each thin film transistor (TFT) 14 (not indicating) is electrically connected to corresponding pixel electrode 13.(grid of the thin film transistor (TFT) 14 that the pixel electrode 13 of the row of 1≤i≤m) is electrically connected (indicating) is electrically connected to i bar sweep trace 11, and (source electrode (indicating) of the thin film transistor (TFT) 14 that the pixel electrode 13 of row of 1≤j≤n) is electrically connected is electrically connected to j bar data line 12 to be positioned at j to be positioned at i.
This display panels 1 also comprises a plurality of data drivers 15 and a plurality of scanner driver 16.This data driver 15 is connected to these many data lines 12 in regular turn and is used to provide gray scale voltage, and this scanner driver 16 is connected to this multi-strip scanning line 11 in regular turn and is used to provide sweep signal.
During this display panels 1 work, this scanner driver 16 scans this multi-strip scanning line 11 in regular turn.Being driven the thin film transistor (TFT) 14 that the sweep trace 11 of device 16 scanning connected by this scanning all opens, meanwhile this data driver 15 inputs to corresponding pixel electrode 13 with the source drain of gray scale voltage by this many data lines 12 and this thin film transistor (TFT) that is opened 14, has realized the loading of one-row pixels electrode 13 gray scale voltages.So repeat, with this m bar sweep trace 11 all scanned in regular turn after, just realized the demonstration of a frame picture.
But not only the demand of large scale liquid crystal TV suddenly increases at present, and " full HD (Full High Definition, Full HD) " LCD TV has become the high-end product in TV market.So-called " full HD " is meant that vertical resolution is 1920 * 1080.Yet the increase of resolution certainly will cause this display panels 1 sweep trace 11 and the quantity m of data line 12, the increase of n.Because each scanner driver 16 and data driver 15 lead-out terminals are limited, so this display panels 1 needs as realizing that high definition then needs more scanner driver 16 and data driver 15 to drive the sweep trace 11 and the data line 12 of increase.
Seeing also Fig. 2, is the electrical block diagram of the display panels of another kind of prior art.This display panels 2 comprises 2m bar be parallel to each other at interval sweep trace 21, n/2 bar space and data line 22, a plurality of be n * m (m>1 vertical with this sweep trace 21, n>1, and n is an even number) pixel electrode 23 of arranged and a plurality of and this pixel electrode 23 thin film transistor (TFT) 24 one to one.The drain electrode of each thin film transistor (TFT) 24 (not indicating) is electrically connected to corresponding pixel electrode 23.((thin film transistor (TFT) 24 grids (indicating) that the pixel electrode 23 of row of 1≤j≤n/2) is electrically connected are electrically connected to 2i-1 bar sweep trace 21 to the row 2j-1 of 1≤i≤m) to be positioned at i; Be positioned at thin film transistor (TFT) 24 grids that the pixel electrode 23 of the capable 2j of i row is electrically connected and be electrically connected to 2i bar sweep trace 21; The source electrode (indicating) that is positioned at the thin film transistor (TFT) 24 that is electrically connected of pixel electrode 23 of 2j-1 and 2j row is electrically connected to j bar data line 22 simultaneously.Change a kind of saying, each row pixel electrode 23 is divided into a plurality of pixel electrodes to 29, each pixel electrode comprises two adjacent pixel electrodes 23 to 29, each pixel electrode is connected to same data line 22 via different thin film transistor (TFT) 24 respectively to 29 two pixel electrodes 23, and this pixel electrode is connected to different sweep trace 21 (being generally and two sweep traces 21 of this pixel electrode to 29 adjacent both sides) to this two pixel electrode 23 of 29 via this two thin film transistor (TFT) 24.
This display panels 2 also comprises a plurality of data drivers 25 and a plurality of scanner driver 26.This data driver 25 is connected to these many data lines 22 in regular turn and is used to provide gray scale voltage, and this scanner driver 26 is connected to this multi-strip scanning line 21 in regular turn and is used to provide sweep signal.
During these display panels 2 work, this scanner driver 26 scans this multi-strip scanning line 21 in regular turn.When this scanner driver 26 is scanned up to 2i-1 bar sweep trace, the thin film transistor (TFT) 24 that odd number during i is capable (promptly be positioned at 2j-1 row) pixel electrode 23 is connected is opened, this data driver 25 inputs to corresponding pixel electrode 23 with the source drain of gray scale voltage by this many data lines 22 and this thin film transistor (TFT) that is opened 24, has realized the loading of odd pixel electrode 23 gray scale voltages in this row; Next, when this scanner driver 26 is scanned up to 2i bar sweep trace, the thin film transistor (TFT) 24 that even number during i is capable (promptly be positioned at 2j row) pixel electrode 23 is connected is opened, this data driver 25 inputs to corresponding pixel electrode 23 with the source drain of gray scale voltage by this many data lines 22 and this thin film transistor (TFT) that is opened 24, has realized the loading of even pixel electrode 23 gray scale voltages in this row.So repeat, treat with this m bar sweep trace 21 all scanned in regular turn after, just realized the demonstration of a frame picture.
This shows, this display panels 2 has reduced half quantity data line 22 compared to this display panels 1, therefore the sweep trace 21 of the quantity that doubles can reduce half quantity data driver 25, the scanner driver 26 of the quantity that doubles.Because each pixel comprises three sub-pixel R, G, B in order to realize full-color demonstration, therefore, for example resolution is actual 5760 data lines and 1080 sweep traces of comprising of display panels of 1920 * 1080.So, adopt the structure such as display panels 2 can reduce by 2880 data lines and only increase by 1080 sweep traces, the data driver quantity that then can reduce is greater than the scanner driver quantity that increases, thus this display panels 2 less cost.
But this scanner driver 26 is expensive, and this scanner driver 26 of a large amount of uses still causes these display panels 2 costs higher.
Seeing also Fig. 3, is the electrical block diagram of the display panels of another prior art.This display panels 200 comprises m/2 bar be parallel to each other at interval sweep trace 210, n bar space and data line 220, a plurality of be n * m (m>1 vertical with this sweep trace 210, n>1, and m is an even number) pixel electrode 230 of arranged and a plurality of and this pixel electrode 230 thin film transistor (TFT) 240 one to one.The drain electrode of each thin film transistor (TFT) 240 (not indicating) is electrically connected to corresponding pixel electrode 230.Being positioned at 2i-1, capable (thin film transistor (TFT) 240 grids that 1≤i≤m/2) and the capable pixel electrode 230 of 2i are electrically connected (indicating) are electrically connected to i bar sweep trace 210; (source electrode (indicating) of the thin film transistor (TFT) 240 that the pixel electrode 230 of 1≤j≤n) is electrically connected is electrically connected to j bar data line 220 simultaneously to be positioned at j row.Wherein, be positioned at the thin film transistor (TFT) 240 that the capable pixel electrode of 2i-1 230 is electrically connected and be P type channel thin-film transistor, be positioned at the thin film transistor (TFT) 240 that the capable pixel electrode of 2i 230 is electrically connected and be N type channel thin-film transistor.Change a kind of saying, each row pixel electrode 230 transmits gray scale voltage by a corresponding data line 220, and per two row pixel electrodes 33 are by the 31 corresponding controls of a sweep trace, and odd-numbered line thin film transistor (TFT) 34 is a P type raceway groove, and even number line thin film transistor (TFT) 34 is a N type raceway groove.
During these display panels 3 work, this scanner driver 36 scans this multi-strip scanning line 31 in regular turn.When this scanner driver 36 is scanned up to i bar sweep trace, this scanner driver 36 offers these i bar sweep trace 31 1 negative pulses earlier opens the thin film transistor (TFT) 34 of the P type raceway groove that the capable pixel electrode 33 of 2i-1 connected, this data driver 35 inputs to corresponding pixel electrode 33 with the source drain of gray scale voltage by this many data lines 32 and this thin film transistor (TFT) that is opened 34, has realized the loading of capable pixel electrode 33 gray scale voltages of 2i-1; Next, this scanner driver 36 offers these i bar sweep trace 31 1 positive pulses opens the thin film transistor (TFT) 34 of the N type raceway groove that the capable pixel electrode 33 of 2i connected, this data driver 35 inputs to corresponding pixel electrode 33 with the source drain of gray scale voltage by this many data lines 32 and this thin film transistor (TFT) that is opened 34, realized 2i capable in the loading of even pixel electrode 33 gray scale voltages.So repeat, treat with this m/2 bar sweep trace 31 all scanned in regular turn after, just realized the demonstration of a frame picture.
As seen, this display panels 3 has further reduced the sweep trace 31 of half quantity compared to this display panels 2, so can further reduce the scanner driver 36 of half quantity.
But general data driver inner structure wants complicated a lot of compared to scanner driver, so the price of data driver also exceeds much compared to scanner driver.The quantity that this display panels 3 can't further reduce data driver 35 makes that these display panels 3 costs are still higher.And, on describe in detail, the quantity of the data line of general display panels is all far more than the quantity of sweep trace, and data line and sweep trace are generally made by lighttight metal material, so the quantity that this display panels 3 can't further reduce data line 32 makes that the opening of this display panels 3 is still lower.
