Description
Technical field
The present invention relates to a kind of LCD, refer to a kind of LCD that promotes aperture opening ratio especially.
Background technology
Function advanced person's display gradually becomes the valuable feature of consumption electronic product now, and wherein LCD has become the display that various electronic equipments such as mobile phone, PDA(Personal Digital Assistant), digital camera, computer screen or the widespread use of mobile computer screen institute have the high-resolution color screen gradually.
LCD comprises two to be had the base material of electrode and is clipped in two liquid crystal layers between base material.Voltage is applied to electrode, makes the liquid crystal molecule quilt in the liquid crystal layer directed again with the control transmittance.Electrode all can be formed on one of base material.One of base material is called " thin-film transistor display panel ", and another base material is called " colour filter (color filter) base material ".Thin-film transistor display panel has plural sweep trace, cross sweep trace and define pixel region data line, be formed on each pixel region and the pixel electrode that is electrically connected to the thin film transistor (TFT) of grid and data line and is electrically connected to thin film transistor (TFT).Storage capacitors is formed on thin-film transistor display panel and is disposed at two liquid crystal between base material so that voltage is applied to stationary mode.For this purpose, the metal wire of storage capacitors can use same metal layer with sweep trace, and itself and pixel electrode are overlapped to form storage capacitors.
See also Fig. 1, Fig. 1 is the partial plan layout of the thin-film transistor display panel 10 of prior art.Thin-film transistor display panel 10 adopts dual-gate polar curve (dual gate) design, when gate drivers (figure does not show) makes the transistor 28 of each row open in regular turn via sweep trace 22 output scanning signals, source electrode driver (figure does not show) then makes it be charged to required separately voltage via the pixel electrode 24 of corresponding data-signal to a permutation of data line 20 outputs simultaneously, to show different GTGs.After same row charging finished, the sweep signal that gate drivers just will be listed as was turn-offed, and then the output scanning signal is charged transistor 28 conductings of next column again by the pixel electrode 24 of source electrode driver to next column.So go down in regular turn, all charge up to all pixel electrodes 24 of thin-film transistor display panel 10 and finish, again since the first row charging.In order to allow pixel electrode 24 when not having sweep signal driving transistors 28, still can show GTG according to data-signal, a storage capacitors electrode wires 26 is set in the corresponding position of pixel electrode 24.Spacing between storage capacitors electrode wires 26 and the pixel electrode 24 is exactly a storage capacitors.Storage capacitors can make pixel electrode 24 maintain fixing voltage till scanning charging next time by the storage data signal.
Yet,, therefore when circuit layout, must consider the restriction of signal coupling (coupling) effect and processing procedure precision though storage capacitors electrode wires 26 is that unlike signal uses same metal level with sweep trace 22.This makes and must keep spacing d1 between storage capacitors electrode wires 26 and the sweep trace 22.Spacing d1 is big more, and the aperture opening ratio of pixel design is more little, and transmitance is lower, and then increases the cost of thin-film transistor display panel 10.

When sweep trace 521 transmitted sweep signal, transistor 581 meeting conductings made can be passed to pixel electrode 61 from data line 50 data-signals.The pixel voltage that pixel electrode 61 received then produces electric field with the voltage difference of the common electrode (not icon) of conducting glass substrate, and drives the liquid crystal molecule rotation of conducting glass substrate and 61 of pixel electrodes.When sweep trace 522 transmitted sweep signal, transistor 582 meeting unlatchings made and can be passed to pixel electrode 62 from data line 50 data-signals.The pixel voltage that pixel electrode 62 received then produces electric field with the voltage difference of the common electrode of conducting glass substrate, and drives the liquid crystal molecule rotation of conducting glass substrate and 62 of pixel electrodes.When sweep trace 523 transmitted sweep signal, transistor 583 meeting unlatchings made and can be passed to pixel electrode 63 from data line 50 data-signals.The pixel voltage that pixel electrode 63 received then produces electric field with the voltage difference of the common electrode of conducting glass substrate, and drives the liquid crystal molecule rotation of conducting glass substrate and 63 of pixel electrodes.When sweep trace 524 transmitted sweep signal, transistor 584 meeting conductings made and can be passed to pixel electrode 64 from data line 50 data-signals.The pixel voltage that pixel electrode 64 received then produces electric field with the voltage difference of the common electrode of conducting glass substrate, and drives the liquid crystal molecule rotation of conducting glass substrate and 64 of pixel electrodes.
In order to allow pixel electrode 61 when not having sweep signal driving transistors 581, still can show GTG according to data-signal, there is the spacing of part overlapping part can form storage capacitors at pixel electrode 61 and the first storage capacitors electrode wires 561 (comprising the first storage capacitors electrode extension line 5611), be used for the storage data signal, make pixel electrode 61 maintain the fixed data voltage of signals till scanning charging next time.The pixel electrode 62 and the second storage capacitors electrode wires 562 (comprising the second storage capacitors electrode extension line 5622) have the spacing of the part that partly weighs can form storage capacitors, be used for the storage data signal, make pixel electrode 62 maintain the fixed data voltage of signals till scanning charging next time.The pixel electrode 63 and the first storage capacitors electrode wires 561 (comprising the 3rd storage capacitors electrode extension line 5613) have the spacing of part overlapping part can form storage capacitors, be used for the storage data signal, make pixel electrode 63 maintain the fixed data voltage of signals till scanning charging next time.The pixel electrode 64 and the second storage capacitors electrode wires 562 (comprising the 4th storage capacitors electrode extension line 5624) have the spacing of part overlapping part can form storage capacitors, be used for the storage data signal, make pixel electrode 64 maintain the fixed data voltage of signals till scanning charging next time.
Because storage capacitors electrode wires 561,562 and sweep trace 521-524 are not to use same metal level not at grade yet, thus need not consider sweep trace 521-524 and storage capacitors electrode wires 561,562 too near and the capacitance coupling effect that causes.On processing procedure, because sweep trace 521-524 and storage capacitors electrode wires 561,562 have the problem of capacitance coupling effect hardly, so (for example between the first storage capacitors electrode extension line 5611 and the sweep trace 522) has less spacing d2 (compared to the spacing d1 of prior art) between tolerable storage capacitors electrode wires 561,562 and the sweep trace 521-524, spacing d2 even can equal 0.So the area of each pixel electrode 61-64 can be bigger, just bigger aperture opening ratio.So can reduce the cost of thin-film transistor display panel 100 and increase usefulness.
