In the practical application, the number of this temperature range is greater than 1 less than a round values of 256, and to be five equilibrium or non-five equilibrium-20 ℃ obtain to 70 ℃ temperature range this temperature range.In this application, temperature sensor is a prior art.
The driving pulse that row-column electrode applied on the display screen be can be low-frequency high-voltage positive negative pulse stuffing and/or high-frequency and high-voltage positive negative pulse stuffing.For example, when display screen is carried out the initialization cls, to the after-applied low-frequency high-voltage positive negative pulse stuffing of row-column electrode elder generation, the high-frequency and high-voltage positive negative pulse stuffing of display screen.Again for example, if the original state of display screen is vaporific lucifuge state, when then display screen shows piece image, to display screen row-column electrode applied is the high-frequency and high-voltage positive negative pulse stuffing.When practical application, the frequency of this low-frequency high-voltage positive negative pulse stuffing is more than or equal to 1Hz and smaller or equal to 100Hz, and its voltage magnitude is more than or equal to 30v and smaller or equal to 150v, and its pulse is more than or equal to 1 and smaller or equal to 500 to number; The frequency of this high-frequency and high-voltage positive negative pulse stuffing is more than or equal to 1kHz and smaller or equal to 50kHz, and its voltage magnitude is more than or equal to 30v and smaller or equal to 150v, and its pulse is more than or equal to 1 and smaller or equal to 1000 to number.
In the reality, when image is shown, can adopt the existing type of drive of sequential scanning line by line (can be referring to Chinese invention patent " driving circuit for smectic state LCD display ", the patent No. is ZL200710304409.2) or other turntable driving modes.No matter adopt which kind of turntable driving mode, show that with display screen piece image is an example under vaporific lucifuge original state, the concrete steps of output driving pulse are on each row electrode 151 of the column electrode 141 of first conductive electrode layer 14 and second conductive electrode layer 15: in a Preset Time, on a column electrode 141 of first conductive electrode layer 14, load a high-frequency and high-voltage positive negative pulse stuffing (Fig. 3 B shows an example of high-frequency and high-voltage positive negative pulse stuffing), on the remaining row electrode 141 of first conductive electrode layer 14, load 0V voltage, simultaneously, on each the row electrode 151 on second conductive electrode layer 15, load a high-frequency and high-voltage positive negative pulse stuffing, wherein: according to the image of smectic liquid crystal display screen needs demonstration, need the high-frequency and high-voltage positive negative pulse stuffing frequency of loading on this column electrode 141 of the high-frequency and high-voltage positive negative pulse stuffing that loads on the row electrode 151 on second conductive electrode layer 15 of driven pixel correspondence and first conductive electrode layer 14 identical on these column electrode 141 positions of first conductive electrode layer 14, voltage magnitude is identical, phase place is opposite, does not need the high-frequency and high-voltage positive negative pulse stuffing frequency of loading on this column electrode 141 of the high-frequency and high-voltage positive negative pulse stuffing that loads on the row electrode 151 on second conductive electrode layer 15 of driven pixel correspondence and first conductive electrode layer 14 identical on these column electrode 141 positions of first conductive electrode layer 14, voltage magnitude is identical, phase place is identical.The pulse of this high-frequency and high-voltage positive negative pulse stuffing is determined according to the temperature range of the current environment temperature correspondence of living in of display screen number and/or voltage magnitude.The voltage magnitude of this high-frequency and high-voltage positive negative pulse stuffing is less than threshold voltage magnitude (U
Threshold), and the voltage magnitude of this high-frequency and high-voltage positive negative pulse stuffing of twice is greater than threshold voltage magnitude.For example, for the waveform shown in Fig. 3 B, then be U
m＜U
Threshold, and 2U
m＞U
Threshold
For example, pulse shown in Fig. 3 B is for regulating the pulse of determining according to environment temperature, the pixel that x column electrode and y row electrode are constituted need be driven, and the pixel that x column electrode and y+1 row electrode are constituted does not need to be driven, so, on x column electrode, load the pulse shown in Fig. 3 B, the pulse of pulse inversion position shown in loading and Fig. 3 B on y row electrode loads on y+1 row electrode and the synchronous pulse of pulse shown in Fig. 3 B (promptly with the pulse together of pulsion phase shown in Fig. 3 B).
Because x column electrode is opposite with impulse phase on y the row electrode, the pulse voltage amplitude that obtains after the superimposed pulses on x column electrode and y the row electrode is 2U
m, and 2U
m＞U
ThresholdSo,, the arrangement form of the smectic phase liquid crystal molecule 131 that x column electrode and y row electrode pair are answered changes, and the pixel that x column electrode and y row electrode are constituted is driven.Specifically, when a pair of frequency identical, voltage magnitude is identical, the high-frequency and high-voltage positive negative pulse stuffing that phase place is opposite is loaded into x column electrode respectively, (this frequency control to the high-frequency and high-voltage positive negative pulse stuffing can make smectic phase liquid crystal molecule 131 that the high-frequency range of regularly arranged form takes place on y the row electrode, its pulse is determined according to the temperature range of the current environment temperature correspondence of living in of display screen number and/or voltage magnitude), and behind this positive negative pulse stuffing effect one Preset Time, the smectic phase liquid crystal molecule 131 that x column electrode is corresponding with the pixel place that y row electrode constituted becomes regularly arranged form, as shown in Figure 6, at this moment, the long optical axis of smectic phase liquid crystal molecule 131 is perpendicular to the conductive electrode layer plane, the ray refraction of each smectic phase liquid crystal molecule 131 of incident does not produce acute variation, light can freely see through x column electrode and y the pixel that the row electrode is constituted, therefore, x column electrode and y the pixel that the row electrode is constituted are crossed in the complete transmission of light, on macroscopic view, the pixel that x column electrode and y row electrode are constituted is the bright state of a kind of full impregnated by vaporific shading state-transition.
Because x column electrode is identical with impulse phase on y+1 the row electrode, the pulse voltage amplitude that obtains after the superimposed pulses on x column electrode and y+1 the row electrode is 0, and 0＜U
ThresholdSo, the arrangement form of the smectic phase liquid crystal molecule 131 that x column electrode is corresponding with the pixel place that y+1 row electrode constituted does not change, the pixel that x column electrode and y+1 row electrode are constituted is not driven, the vaporific shading state of (display screen init state) when keeping display image not.The microscopic pattern of the vaporific shading state during the display screen init state as shown in Figure 5, smectic phase liquid crystal molecule 131 is out of order arrangement form.Particularly, when a pair of frequency identical, voltage magnitude is identical, (Fig. 3 A shows an example of low-frequency high-voltage positive negative pulse stuffing to the low-frequency high-voltage positive negative pulse stuffing that phase place is opposite, this frequency control to the low-frequency high-voltage positive negative pulse stuffing can make the smectic phase liquid crystal molecule that the low-frequency range of out of order arrangement form takes place, its pulse is determined according to the temperature range of the current environment temperature correspondence of living in of display screen number and/or voltage magnitude) be loaded into first respectively, second conductive electrode layer 14, on 15, and behind this positive negative pulse stuffing effect first setting-up time, smectic phase liquid crystal molecule 131 in the mixolimnion 13 just twists, and forms out of order arrangement form shown in Figure 5.Because each of smectic phase liquid crystal molecule 131 (promptly passed through the long optical axis difference of each liquid crystal to diversity owing to incident ray, the anaclasis angle difference of each liquid crystal, thereby the refractive index difference of each liquid crystal), make the ray refraction of each smectic phase liquid crystal molecule 131 of incident exist very big difference, promptly in the mixolimnion 13 of this meagre thickness, optical index is producing violent variation, thereby strong scattering has taken place in light, present astigmatic effect, on macroscopic view, smectic liquid crystal display screen presents a kind of as the vaporific shading state as the acute-matte.And, though each row electrode all has pulse to load,, except x column electrode load pulses, because other column electrodes all connect 0V voltage, therefore, it is U that all pixels on other column electrode positions all are in amplitude
mPulse action under, these pixels can not be driven.
In the present invention, threshold voltage is smectic phase liquid crystal molecule 131 to be driven the magnitude of voltage that arrangement form changes takes place, and it is to determine according to the composition of mixolimnion 13 and thickness, is generally more than the 50V.In addition, in the present invention, a direct impulse in the low-frequency high-voltage positive negative pulse stuffing adds a negative-going pulse, and to be called as a pulse right, and in the same manner, a direct impulse in the high-frequency and high-voltage positive negative pulse stuffing adds a negative-going pulse and is called as a pulse to (for example shown in Fig. 3 A and Fig. 3 B).Corresponding time span can be calculated according to the frequency and the pulse that load the low-frequency high-voltage positive negative pulse stuffing to number, in the same manner, corresponding time span can be calculated to number according to the frequency and the pulse that load the high-frequency and high-voltage positive negative pulse stuffing.
In the reality, according to showing needs, also can be mixed with a certain amount of dichroic dye in the mixolimnion 13, like this, smectic liquid crystal display screen 1 just can switch between the bright and coloured shading of full impregnated.For the smectic liquid crystal display screen 1 that has mixed dichroic dye, the smectic liquid crystal display screen identical (its image Display Realization principle is similar to the smectic liquid crystal display screen of above-mentioned unmixed dichroic dye) of its driving method and above-mentioned unmixed dichroic dye here repeats no more.In addition, can make the arrangement form of smectic phase liquid crystal molecule 131 that the part distortion take place by pulse voltage amplitude size, frequency and the time that control is applied on two conductive electrode layers 14 and 15, produce astigmatic effect in various degree, at the multiple progressive state that shows as the different gray scales rank between vaporific and bright two states of full impregnated on the macroscopic view, as translucent etc.
The present invention has advantage: the inventive method has the characteristic of temperature self-adaptation, when environment temperature changes, the present invention can regulate the voltage magnitude of driving pulse and/or pulse to number according to the variation of environment temperature, the deflection that the smectic phase liquid crystal molecule can be expected under the driving of the driving pulse after the adjusting, thus make image can reach the display effect of expection.The present invention can make smectic liquid crystal display screen stably show under different environment temperatures, and the display effect of image is not subjected to the influence of environment temperature.
The above is preferred embodiment of the present invention and the know-why used thereof; for a person skilled in the art; under the situation that does not deviate from the spirit and scope of the present invention; any based on conspicuous changes such as the equivalent transformation on the technical solution of the present invention basis, simple replacements, all belong within the protection domain of the present invention.
