Referring to Fig. 4, the dot structure be arranged on first substrate 11 is described in detail.Can see, the first film transistor 43 and the second thin film transistor (TFT) 44 is also provided with in pixel region, wherein, the grid 431 of the first film transistor 43 is electrically connected with grid line 41, source electrode 432 is electrically connected with the first data line 421, drain electrode 433 electrical connection is positioned at the first pixel electrode 111 of the planar of transmission area, the grid 441 of the second thin film transistor (TFT) 44 is electrically connected with grid line 41, source electrode 442 is electrically connected with the second data line 422, drains 443 and is electrically connected with the second pixel electrode 112 being positioned at the spaced strip in echo area.Like this in energising situation, first data line 421 can apply voltage by the first film transistor 43 to the first pixel electrode 111, second data line 422 can apply voltage by the second thin film transistor (TFT) 44 to the second pixel electrode 112, public electrode (not shown in Fig. 4) provides voltage by public electrode wire, make the first pixel electrode 111 and between the second pixel electrode 112 and public electrode, produce uniform vertically electric field, slit place between second pixel electrode 112 and the just right region of public electrode then can produce the tilting electric field with certain level component, to drive liquid crystal mesogens display panel.
It should be noted that, the first data line 421 and the second data line 422 can be arranged at the optional position in pixel region in parallel to each other.In display panels as shown in Figure 4, the first data line 421 and the second data line 422 lay respectively at the both sides of pixel region.So, the second data line 422 being positioned at current pixel region is closely adjacent with the first data line 421 of adjacent pixel regions, thus without the need to additionally increasing black matrix structure to block the second data line 422, ensure that the aperture opening ratio of display panels.
Further, first data line 421, second data line 422 can apply different voltage respectively to the first pixel electrode 111, second pixel electrode 112, makes the phase-delay quantity through the transmitted light of transmission area outgoing flux matched with the phase delay through the reflected light of echo area outgoing.
In embodiments of the present invention, liquid crystal layer can adopt negative liquid crystal molecule, and when electric field is enough strong, negative liquid crystal molecule will arrange perpendicular to direction of an electric field.
In energising situation, different voltage can be applied respectively to the first pixel electrode, the second pixel electrode by the first data line, the second data line, be correlated with as the determination of magnitude of voltage and the character (as: refractive index properties, dielectric anisotropy character etc.) of negative liquid crystal that are applied to two pixel electrodes.Specifically according to following method of testing for the panel comprising specific a kind of negative liquid crystal, the relation of two magnitudes of voltage can be determined.First, according to manufacturing test panel in advance, above-mentioned specific a kind of negative liquid crystal in this test panel, is filled.Secondly, voltage is applied to the first pixel electrode of transmission area by the first data line, voltage is applied to the second pixel electrode of echo area by the second data line, draw the transmission area of this test panel and V-T (voltage-transmitance) curve characteristic of echo area respectively, analyze the curve characteristic in two regions, and obtain the magnitude of voltage of first, second data line corresponding to the consistent position of each transmitance successively.In embodiments of the present invention restriction is not added to the above-mentioned magnitude of voltage being applied to two pixel electrodes, be as the criterion so that the phase-delay quantity that the transmission area of same pixel region and the light of echo area can be made in actual production to be produced by negative liquid crystal layer is identical.Similar with previous embodiment, in embodiments of the present invention, the width of the second pixel electrode is between 0.5-2 μm, and the spacing between adjacent two described second pixel electrodes is between 5-10 μm.
Adopt a kind of like this display panels of structure, the first pixel electrode is not connected with the second pixel electrode, and this first pixel electrode is powered by the first data line, and the second pixel electrode is powered by the second data line.So, namely effectively can control by the driving voltage changing the first pixel electrode and the second pixel the phase-delay quantity that liquid crystal layer produces, thus considerably increase the dirigibility that display panels controls.
Below, how to realize semi-transparent semi-reflecting display for the above-mentioned display panels provided to be described in detail.
Be structure as a whole for the first pixel electrode 111 and the second pixel electrode 112, Fig. 1 is the structural representation of display panels when not powering up.When not making alive, liquid crystal molecule is all perpendicular to substrate orientation, and liquid crystal molecule layout viewing now as shown in Figure 5.Exemplary, in the display panels shown in Fig. 5, the thickness of liquid crystal cell is preferably 4.4 μm, the width of the second pixel electrode preferably 1 μm, the spacing between adjacent two described second pixel electrodes preferably 8 μm.For so a kind of display panels, can not optically-active be there is in the light of transmission area and echo area through this liquid crystal layer, thus also would not produce phase-delay quantity, if the polarization direction of the first polaroid 115 and the second polaroid 123 is 90 degree of angles, emergent ray can be blocked completely by the first polaroid 115, thus realizes good dark-state display.
Fig. 6 is the structural representation of the display panels shown in Fig. 1 when powering up.Wherein, produce uniform vertically electric field between the first pixel electrode 111 and common electrode layer 121, the negative liquid crystal molecule of transmission area gradually becomes horizontal due to the impact by vertical electric field, produces the phase delay of horizontal direction; In echo area, the negative liquid crystal molecule that second pixel electrode 112 and common electrode layer 121 facing portion are divided gradually becomes horizontal due to the impact by vertical electric field, produce the phase delay of horizontal direction, and be vergence direction arrangement at echo area second pixel electrode 112 and the right partial electric-field line of common electrode layer 121 anon-normal, negative liquid crystal molecule gradually becomes oblique arrangement due to the impact by tilting electric field, produce the phase delay of vergence direction, liquid crystal molecule layout viewing now as shown in Figure 7.Exemplary, in the display panels shown in Fig. 7, the thickness of liquid crystal cell is preferably 4.4 μm, the width of the second pixel electrode preferably 1 μm, the spacing between adjacent two described second pixel electrodes preferably 8 μm equally.Negative liquid crystal can produce larger horizontal phase and postpone Δ n1 under the vertical electric field action in transmission area, and meanwhile, the negative liquid crystal of echo area can produce less horizontal phase and postpone Δ n2 under vertical electric field and tilting electric field acting in conjunction.Therefore, by echo area second pixel electrode spacing or the optimization of voltage between transmission area and echo area, the light through transmission area being produced and postpone than the more horizontal phase in echo area, is namely probably Δ n transmission area=2* Δ n echo area.And the light of echo area is because reflection is equivalent to twice through liquid crystal layer, light path doubles, namely d echo area=2*d transmission area.To sum up, transmission area (Δ n*d)=echo area (Δ n*d) can be obtained, thus achieve the coupling of the phase-delay quantity of transmission area and echo area, and finally reach semi-transparent semi-reflecting display effect.
Can not be connected with the second pixel electrode for above-mentioned the first pixel electrode provided, this first pixel electrode is energized by the first data line, how this second pixel electrode realizes semi-transparent semi-reflecting display by the display panels that the second data line carries out powering with reference to above-mentioned principle, can not add at this and repeats.
