Description of the Invention (/) Background of the Invention 1 (1) Prior and Current Technology Levels: So far, the operating principle of polymer dispersed liquid crystal displays is as shown in Figure 2 As shown, the liquid crystal held in the bundle-shaped transparent polymer shows a stable state. 5 Using an external electric field, the refractive index change of the liquid crystal can be controlled, and the refractive index difference between the polymer and the liquid crystal can be adjusted to control the optical transparency and optics of the display. The state of divergence. The polymer-dispersed liquid crystal display devices made by using this principle of action include US Patent No. 4,435,047 from JLFergasori in 1984 and JWDoane et al. Appl. Phys. Lett. The liquid crystal spheres of the linear liquid crystal are arranged in a polymer layer. When there is no external electric field, the equivalent refractive index neff of the liquid crystal does not match the high refractive index ΠP, which makes the display in an optically dispersed state. When there is an external electric field, the equivalent refractive index of the liquid crystal nef f = constant light of the liquid crystal Refractive index n0 = polymer refractive index np, so the refractive indexes of liquid crystal and polymer match each other, so that the display is optically transparent. In addition, in 1991, T. Gotoh et al., On the LCD Conference, page 328, proposed that after mixing the two-line liquid crystal with an optically isotropic ultraviolet Jie resin, the polymer was cured by irradiating ultraviolet rays under an external low-frequency electric field. , And then use high-frequency electric field for driving. Therefore, this reverse display polymer dispersed liquid crystal display can be optically transparent when no external electric field is applied; when it has an external electric field 20, it can be optically three-dimensionally scattered. However, the qualitative problem of Eryu liquid crystal materials has not been solved at present. In addition, pp. 00ker. Et al., 1990, Appl. Phys. Lett, Vol. 57, p. 2529, proposed the use of cholesteric liquid crystals, or the infiltration of chiral liquid crystals into 24 cells, so that This liquid crystal has a selective reflection effect on the wavelength of light, so the 2 K display is installed ------ π ------ t (please read the notes on the back before filling this page) Applicable to China National Standard (CNS > A4 specification (210X297 mm)) Printed by Aberdeen Consumer Cooperative of the Central Bureau of Standard Vehicles of the Ministry of Economic Affairs A7 B7 _ —-------- " V. Description of Invention (I) 1 display color. Also, the concept of this color was also proposed by HSKitzerow et al. In 1992, Appl. Phys · Let · Vol. 60, p. 3093, applied to a rotating layer with fast queue conversion characteristics. (Chiral smetic) high-dispersion pre-dispersed liquid crystal display made by wave crystal. 5 Therefore, polymer-dispersed liquid crystal displays made according to known methods can be divided into two display modes: 液晶 When no external electric field is applied, the liquid crystal It presents a sloppy arrangement and thus produces an optically disordered state; and when an electric field is applied, the liquid crystals are arranged neatly The optically transparent state 10 is generated, and this frequency display method is called polymer dispersed liquid crystal (PDLC). (2) When no external electric field is applied, the liquid crystal queues are neat and optically transparent. And when an electric field is applied, the wave crystals are scattered to produce an optically scattered state. This kind of particle display method is called reverse-mode display polymer dispersed liquid crystal (RPDLC) reverse mode 15 polymer dispersed liquid crystal indicator. In addition, Paul S. Drzaic et al., SPIE, page 41, 1989 proposed the use of guest-host type liquid crystals containing dichroic dyes to make host-guest polymer dispersed liquid crystal displays with both dispersion and absorption effects ( PDLC) 20 and host-guest reverse display polymer dispersed wave crystal display (RPDLC), etc., two types of polymer dispersed liquid crystal display devices. JWDoane et al., 1991 IEEE page 175, proposed the use of linear liquid crystal and踌 Phase transfer of liquid crystal to make a reverse display dispersive liquid crystal display (RPDLC) with the properties of memory. 24 3 This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm)!,- ----- install ------ -------- Tie VI (Please read the notes on the back before filling in this page) Printed by the Central Government Bureau of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, printed A7 _________B7_ V. Description of the Invention (>) 1 (2) This Problems to be solved by the invention: Until now, whether it is a polymer dispersed liquid crystal display (pDLc) or a reverse display polymer dispersed liquid crystal display (RPDLC), the display method of these polymer dispersed liquid crystal displays has existed. The following problems need to be solved: 1. In terms of contrast, polymer dispersed liquid crystal displays such as polymer dispersed plastic liquid crystal display (PDLC) and reverse display polymer dispersed liquid crystal display (RPDLC) *. 90 degree rotating liquid crystal (TH) display or super-angle rotating liquid crystal (STN) display for general commercial products. Therefore, how to improve the contrast is a problem that must be solved urgently. 2. In terms of the sharpness of the transmittance-voltage curve, since the liquid crystal is located between the liquid crystal-polymer interface at unequal intervals, the interface anchor force on the liquid crystal molecules in each liquid crystal region is also It varies with 15 distances between interfaces. Therefore, the initial voltages that cause the liquid crystal molecules to start rotating in each region are also different, which is the reason that the severity of the transmittance-voltage curve is bad. 3. As far as the driving voltage is concerned, in order to make full use of the dispersion effect of the liquid crystal-polymer layer on the liquid crystal display (20 PDLC) and the reverse display dispersive liquid crystal display (RPDLC), the gap between the liquid crystal and the polymer must be increased. The phase separation interface thus relatively increases the anchoring force of the liquid crystal molecules, so that its driving voltage also increases. Therefore, the driving voltage of dispersive plastic liquid crystal display 24 (PDLC) or reverse display liquid crystal display (RPDLC) is far _ 4 1 This paper size uses China National Standard (CNS) A4 specification-U10X297 mm) I n I n I _ I n LK.

Description of the Invention (4) 1 Higher than the liquid crystal display device driven by the simple matrix method, and higher than the liquid crystal display device driven by the active matrix method. It is extremely difficult to manufacture the driving circuit. In addition, the phase transfer of linear liquid crystal and cholesteric liquid crystal is used to make a reverse display dispersive liquid crystal display (RPDLC) with a memorable quality of 5. Due to the addition of rotational free energy The driving voltage is higher and the practicality is more difficult. The present invention is used to improve or solve the above problems and achieve the following failures: 10 1. Increase the contrast: The present invention uses methods such as friction and external electric field. Polymer The mixture of the driver, liquid crystal, and dye is processed to make the orientation changes of the liquid crystal molecules scattered in the two-dimensional space plane of the parallel substrate surface, and the methods such as ultraviolet light, heating, and solvent evaporation are used to form the alignment plus dyes. The molecular plane disperses the liquid crystal display. Compared with the past, the orientation change of the gray crystal molecules 15 is scattered in a three-dimensional space plane. In the scattered state of the present invention, due to the absorption of light by the dye molecules, and sufficient The mismatch between the refractive index of the polymer and the liquid crystal is brought into play, so that the transmittance of the polymer dispersed liquid crystal display is greatly reduced; while in the transparent state, the transmittance of the present invention is theoretically equal to that of the polymer dispersed liquid crystal display in the past. The penetration ratio. The contrast ratio of 20 degrees is the penetration ratio between the bright state and the scattered state, so the contrast of the present invention can be higher than the contrast ratio of the polymer dispersion liquid crystal display in the past. Severity • · Because the voltage that causes the highest or lowest point penetration rate is the starting voltage or saturation voltage, respectively, the penetration rate of the paper Standards apply to Zhongguanjia County (CNS) A4 «iS · (21GX297 male g '~~' — ------- k installed ------ ix-; ---- line (please read first Note on the back, please fill in this page again.)

Description of the invention (;) , Divided by the difference between the starting voltage and the saturation voltage. Therefore, in the case of no torsional free energy, the starting or saturation voltage of the present invention is theoretically equal to the starting or saturation voltage of a polymer dispersed liquid crystal display in the past. The voltage difference between the two is equal; but the penetration 5 rate is due to the sharp reduction of the transmittance in the scattered state of the present invention, which results in an increase in the difference in transmittance, which also makes the transmittance-voltage curve of the present invention Urgency. Higher than the previous polymer dispersed wave crystal display. 3. Decrease the driving voltage: because the higher the interface anchoring force 10 (liquid crystal force) the liquid crystal molecules are, the harder it is for the liquid crystal molecules to rotate, and the driving voltage will increase accordingly. In the case of torsional free energy, the present invention uses friction, an external electric field, and other methods to cause torsional alignment, and generates additional torsional free energy. The additional torsional free energy and the intrinsic free energy of the liquid crystal molecules cancel each other, so that the total elastic free energy is reduced, and the driving voltage is also reduced accordingly. Conversely, in the past 15, polymer dispersed liquid crystal display devices made of chiral smetic liquid crystals, or phase transfer of linear liquid crystals and cholesteric liquid crystals have been used to make them. The polymer-dispersed liquid crystal displays all increase the total free energy due to the pile of liquid crystal molecules and the inherent torsional free energy, thereby increasing the driving voltage. 20 (3) The technical domain of the present invention: The present invention is a polymer flat-dispersed liquid crystal display used in watch display, self-service display, and projector display. 24__ __6 _ This paper is suitable for CNS Standard (CNS) Ya 4 threats (21〇 × 297 public envy) '(Please read the precautions on the back before filling out this page) " Binding_ Order .4 I A7

Trends in 15 planes. The polymer planar dispersed liquid crystal of the present invention may also be a linear liquid crystal and an optically anisotropic polymer. By using the alignment process on the substrate, the orientation of the liquid crystal molecules and the polymer precursors has a tendency of being distributed in a two-degree space plane parallel to the surface of the substrate, and the orientation of the liquid crystal molecules and the polymer precursors is in the two-degree space plane.

Explanation of the invention (ο) 1 The contrast ratio is indeed higher than the dispersion type liquid crystal display (PD1X) known by f. When the polarizing direction of the incident light is perpendicular to the alignment direction of the sample, its characteristics such as 403, the lowest light transmittance is similar to 401, but the lowest transmittance is higher than 401, which can prove that the polymer plane of the present invention The 5 molecules of liquid crystal of the dispersed liquid crystal display (PPDLC) are subjected to the effect of alignment treatment. Therefore, if the light source is linear polarized aurora, when the polarized direction of the incident light is parallel to the alignment direction of the polymer flat dispersion liquid crystal display (PPDLC) of the present invention, the contrast of the monitor is better than the conventional polymer dispersed liquid crystal display. (PDLC). 10 [Example 2] Isotropic polymer + rotating alignment liquid crystal Please read the cross-sectional view of a polymer flat dispersion liquid crystal display (PPDLC) according to the present invention as shown in FIG. 1. Using the same material, the method of producing and broadcasting according to Example 1 was followed by plating an electrode with an alignment film PVA (j > 〇lyVinyl alch〇h〇l) 15 and using a cloth to rub unidirectionally on the electrode surface for orientation treatment. The electrode surfaces of the two substrates are opposite to each other, the alignment directions are perpendicular to each other, and the thickness of the sample is taken as un to form an empty sample. At 100 t: the same mixture was sealed in the gap between the empty samples. This sample was slowly cooled to 50, and the liquid crystal molecules in the mixture were rotated in a 20-degree row from the lower base to the upper substrate along the alignment direction. The step of making Buddha is continued. After the polymer and liquid crystal are phase-separated, a polymer planar dispersion liquid crystal (ppj ^ c) display of the present invention is completed as shown in FIG. 1. Before the electric field was applied, the sample was in a state of scattered white turbid light, and the electric field was in a transparent state.

Description of the invention (/ in) 1 Polymers are indeed optically isotropic. The same material is used to eliminate the alignment treatment, and a conventionally known type of polymer dispersed liquid crystal display (PDLC) sample is prepared. The photoelectric characteristics of the two are measured. When natural light is incident perpendicularly to the PDLC of the known type and the PPDLC sample of the present invention, the relationship between the transmittance and the ac voltage is shown in FIG. 5. 501 represents the photoelectric characteristics of a conventional type of polymer dispersed liquid crystal (PDLC) display sample, and 502 represents the photoelectric characteristics of the polymer planar dispersed liquid crystal (PPDLC) display device sample of the present invention. Because the orientation of the liquid crystal molecules in each liquid crystal region of the polymer-dispersed liquid crystal (PDLC) display sample of the known type is three-dimensionally spaced, the 10 liquid crystal molecules in each liquid crystal region of the sample of the present invention are oriented at two degrees. The space is scattered randomly, so the lowest transmittance of the polymer flat dispersion liquid crystal display (PPDLC) sample of the present invention is lower than the past. The lowest transmittance of the pre-dispersed liquid crystal (PDLC) display sample is lower, and the lowest Light transmittance is similar. It can be seen that the contrast ratio of the polymer planar dispersed liquid crystal (PPDLC) display of the present invention is indeed higher than that of the polymer dispersed wave crystal (pdlc) 15 display known by f. It can also be seen from Fig. 5 that the severity of the photoelectric characteristic curve of the present invention is higher than that of the conventional one. In terms of driving voltage, although the starting voltage of the present invention is higher than that of f, the saturation voltage is lower than that of f. In addition, the optical characteristics of the two samples of the polymer flat dispersion liquid crystal display (PPDLC) of the present invention are the rotation 20 alignment (Example 2) and parallel alignment (Example 1), as shown in Figures 502 and 囷 4, 402 and 403. The maximum light transmittance is about the same, but the minimum transmittance is 402 minimum, 502 times, and 403 maximum. Therefore, when the light source is linearly polarized aurora, the parallel alignment of Example 1 of the present invention can be used to improve the contrast; when the light source is "For Natural Light", the rotation of Example 2 of the present invention is adopted. _15 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) II ^ 丨 .----- k-pack -------- Order—: ---. 丨 Girl (please read the precautions on the back before filling this page) A7 B7 5 V.

Comparative Example 2 Optoelectronic characteristics 502 of the unpigmented polymer planar dispersive liquid crystal (PPDLC) display sample of the present invention and optoelectronic characteristics 702 of the dyed polymer planar dispersive liquid crystal 15 display device sample. Since JLWest et al. When the external light intensity is adjusted to the optimal value, the contrast of the polymer dispersed wave crystal (PDLC) display with dye is of course greater than that of the spin-dispersed liquid crystal (PDLC) display without dye; however, the dye is added. The contrast of the sample is not greater than that of the sample without dye in Example 2, because the UV intensity in this example has not been adjusted to the optimal value, that is, the scattering effect is not maximized. 24 17.- --------------- ding • I -s (Please read the notes on the back before filling out this page) t The paper size applies to the ten national standards (CNS) A4 specifications (210X297 mm )
