Moreover traditional FLC display panel utilizes the photoelectricity bistable characteristic (photoelectrically bistable behavior) of the liquid crystal of stratose liquid crystal layer to do demonstration, and its GTG display mode has three, and division is as follows.
First kind of mode is the elemental area split plot design, and its shortcoming is that to cut apart sub-pixel many more, and the yield of production (yield) is just low more.
The second way is the image time split plot design, and its shortcoming is to need driving circuit at a high speed, with the cutting GTG.
The third mode is the driving voltage split plot design, and its shortcoming is to utilize voltage swing to drive to have the display panels of photoelectricity bistable characteristic, and it is very complicated that driving voltage waveform and driving circuit all become.

Please be simultaneously with reference to Fig. 1～2A, Fig. 1 illustrates the schematic top plan view according to the circuit framework of the display panels of embodiments of the invention one, and Fig. 2 A illustrates the synoptic diagram of the cut-away section structure of the display panels of being looked along the profile line 2A-2A ' of Fig. 1.In Fig. 1～2A, display panels 10 comprises active matrix 15, first electrode 17, second electrode 18, the first vertical orientation film 19, the second vertical orientation film 22 and stratose liquid crystal layer (smectic liquid crystal layer) 13.Active matrix 15 has one or more switch modules and one or more pixel, is arranged on first substrate 11.Each pixel by be arranged at two adjacent on first substrate 11 sweep traces (scan line, or gate line) and adjacent two data lines (data line, or source line) at interval institute define and form.In the present embodiment, active matrix 15 is that example explains with pixel P1, pixel P1 by the first adjacent sweep trace S1 and the second sweep trace S2 and the adjacent first data line D1 and the second data line D2 at interval institute define and form.Switch module 16 is arranged at pixel P1 in the mode that is positioned on first substrate 11, and switch module 16 and the first sweep trace S1 and first data line D1 electric connection.Switch module 16 can be a transistor, for example be thin film transistor (TFT) (thin film transistor, TFT).
First electrode 17 is arranged at pixel P1 in the mode that is arranged on first substrate 11, and electrically connects with switch module 16.First electrode 17 has one or more first electrode connecting portion 17a and several first electrode part 17b that is parallel to each other.At this, electrically connecting with the first electrode connecting portion 17a and these first electrode part 17b is that example explains, this first electrode connecting portion 17a and vertical connection of these first electrode part 17b.Second electrode 18 is arranged at pixel P1 in the mode that is arranged on first substrate 11, and has one or more second electrode connecting portion 18a and several second electrode part 18b that is parallel to each other.At this, electrically connecting with the second electrode connecting portion 18a and these second electrode part 18b is that example explains, this second electrode connecting portion 18a and vertical connection of these second electrode part 18b.Wherein, the first electrode connecting portion 17a and the second electrode connecting portion 18a are parallel to each other, these second electrode part 18b and these first electrode part 17b are parallel to each other and are spaced, and each second electrode part 18b is with a set interval d and the first adjacent electrode part 17b parallel arranged.Each first electrode part 17b is with this set interval d and adjacent second electrode part 18b arrangement.Set interval d scope is essentially 5 microns (μ m)～50 microns (μ m).In the present embodiment, first electrode 17 and second electrode 18 are just like as being spaced face-to-face as two comb shape structures.By applying alternating voltage in first electrode 17 and second electrode 18, changing the polarity of first electrode 17 and second electrode 18, and arbitrary adjacent first electrode part 17b and the formed transverse electric field direction of the second electrode part 18b surface that is parallel to first substrate 11.
The first vertical orientation film 19 is arranged on first substrate 11, and covers first electrode 17 and second electrode 18.The second vertical orientation film 22 is arranged on second substrate 12.
Stratose liquid crystal layer 13 is arranged between first substrate 11 and second substrate 12, and between the first vertical orientation film 19 and the second vertical orientation film 22.Stratose liquid crystal layer 13 has a plurality of liquid crystal molecule 13a.In the phase transition process of the liquid crystal molecule 13a of stratose liquid crystal layer 13, by applying the transverse electric field that this alternating voltage is produced in first electrode 17 and second electrode 18, the liquid crystal molecule 13a orientation of auxiliary stratose liquid crystal layer 13.
When first electrode 17 and second electrode 18 were not applied to voltage, when promptly not producing transverse electric field between first electrode 17 and second electrode 18, the average optical axis makes of stratose liquid crystal layer 13 was in fact perpendicular to the first vertical orientation film 19 and the second vertical orientation film 22.When first electrode 17 and second electrode 18 were applied in voltage, when promptly producing transverse electric field between first electrode 17 and second electrode 18, the average optical axis makes of the liquid crystal molecule 13a of stratose liquid crystal layer 13 tilted with the transverse electric field direction.
In addition, the anchoring energy of vertical orientation film (anchoring energy) is relevant with the driving voltage of display panels.When the anchoring energy of vertical orientation film strong more, be that the vertical orientation film provides strong anchoring energy (strongly anchoring energy) for the liquid crystal molecule that approaches the vertical orientation film in the liquid crystal layer, display panels then needs big more driving voltage, can rotate liquid crystal molecule.Otherwise, when the anchoring energy of vertical orientation film weak more, be that the vertical orientation film provides a weak anchoring energy (weakly anchoring energy) for the liquid crystal molecule that approaches the vertical orientation film in the liquid crystal layer, display panels only needs more little driving voltage, can the brilliant molecule of hydrodynamic.In view of this, based on keeping under the prerequisite of vertical orientation film for the liquid crystal molecule vertical orientation,, just can reduce the driving voltage of display panels if can weaken the anchoring energy of vertical orientation film.In the present embodiment, the first vertical orientation film 19 provides first anchoring energy for the liquid crystal molecule 13a near the first vertical orientation film 19 in the stratose liquid crystal layer 13, the second vertical orientation film 22 provides second anchoring energy for the liquid crystal molecule 13a near the second vertical orientation film 22 in the stratose liquid crystal layer 13, and first anchoring energy and second anchoring energy are inequality.Wherein, first anchoring energy and second anchoring energy are the matched combined of a strong anchoring energy and a weak anchoring energy, and strong anchoring can be greater than weak anchoring energy.For example, first anchoring energy and second anchoring energy are respectively a strong anchoring energy and a weak anchoring energy.Or first anchoring energy and second anchoring energy are respectively a weak anchoring energy and a strong anchoring energy.At this, the first vertical orientation film 19 and the second vertical orientation film 22 are to have a strong anchoring energy respectively and a weak anchoring energy is that example explains.Wherein, the second vertical orientation film 22 with weak anchoring energy can be finished after vertical orientation film process friction (rubbing) method with strong anchoring energy, and rubbing manipulation can be weak friction (soft rubbing) method.
The difference decision of strong rubbing manipulation and weak rubbing manipulation in orientation with the size that press down strength of the flannelette on the roller on alignment film.If orientation with the flannelette on the roller on alignment film to press down strength bigger, the groove on the alignment film can be darker, this is to belong to strong rubbing manipulation.Wherein, the mean level alignment film is used strong rubbing manipulation and is finished.If orientation with the flannelette on the roller on alignment film to press down strength less, the groove of alignment film can be more shallow, this is to belong to weak rubbing manipulation.Wherein, the vertical orientation film of present embodiment is used weak rubbing manipulation, so the degree of depth of the groove of the depth ratio mean level alignment film of the groove that produces after the weak rubbing manipulation of the vertical orientation film of present embodiment process is also shallow.
As for the arranging situation of liquid crystal molecule 13a when two vertical orientation films have the strong anchoring energy, as follows at this description of drawings.Please refer to Fig. 2 B, its illustrate liquid crystal molecule in the first vertical orientation film and the second vertical orientation film have strong anchoring can the time the synoptic diagram of ordered state.In Fig. 2 B, stratose liquid crystal layer 13 is arranged between the first vertical orientation film 19 and the second vertical orientation film 22a, and the second vertical orientation film 22a provides a strong anchoring energy for the liquid crystal molecule 13a near the second vertical orientation film 22a in the stratose liquid crystal layer 13.Therefore, when not applying driving voltage in the first electrode part 17b and the second electrode part 18b, liquid crystal molecule 13a has arrangement situation difference in the different anchoring energies in two vertical orientation films, especially is adjacent to the arrangement situation of that one deck liquid crystal molecule of two vertical orientation films.The major axis of that one deck liquid crystal molecule 13a that is adjacent to the second vertical orientation film 22a is almost perpendicular to the surface of the second vertical orientation film 22a, and the major axis of that one deck liquid crystal molecule 13a that is adjacent to the second vertical orientation film 22 is a little with respect to the surface tilt of the second vertical orientation film 22a.
Please be simultaneously with reference to Fig. 3～4, it illustrates first electrode of Fig. 2 A and two synoptic diagram that second electrode is applied in the formed transverse electric field distribution of alternating voltage.Wherein, Fig. 3 also can be expressed as first electrode of Fig. 2 B and the part synoptic diagram that second electrode is applied in the formed transverse electric field distribution of alternating voltage.Shown in Fig. 3～4, first electrode 17 and second electrode 18 are applied in alternating voltage in the phase transition process of the liquid crystal molecule 13a of stratose liquid crystal layer 13, to change the polarity of first electrode 17 and second electrode 18.If first electrode 17 and second electrode 18 are respectively positive polarity and negative polarity in first during applying voltage, then first electrode 17 and second electrode 18 are respectively negative polarity and positive polarity in second during applying voltage, first electrode 17 and second electrode 18 apply during the voltage with first and second apply the mode that replaces during the voltage and be applied in alternating voltage, with switch polarity.Therefore, formed transverse electric field direction all is parallel to the surface of first substrate 11 between these first electrode part 17b and these the second electrode part 18b.And each first electrode part 17b and the adjacent formed transverse electric field direction of the second electrode part the 18b first electrode part 17b and the adjacent formed transverse electric field direction of another second electrode part 18b therewith are opposite.For the adjacent first electrode part 17b and the second electrode part 18b, the first electrode part 17b of first electrode part 17b of positive polarity and the second electrode part 18b of negative polarity formed transverse electric field direction and negative polarity during first voltage applies and the second electrode part 18b formed transverse electric field direction during second voltage applies of positive polarity are opposite.
