LIQUID CRYSTALLINE MEDIUM

Description

[0001] The invention relates to a liquid crystalline medium comprising the compound of formula I, and additionally contains one or more biphenyls of formulas B-1 to B-4. Such media are particularly suitable for electro-optical displays with active matrix addressing based on the ECB effect, as well as for IPS (in-plane switching) or FFS (fringe field switching) displays.

[0002] The principle of electrically controlled birefringence, the ECB effect (electrically controlled birefringence) or DAP effect (deformation of upright phases), was first described in 1971 (MF Schieckel and K. Fahrenschon, "Deformation of nematic liquid crystals with vertical orientation in electrical fields", Appl. Phys. Lett. 19 (1971), 3912). This was followed by work by J.F. Kahn (Appl. Phys. Lett. 20 (1972), 1193) and G. Labrunie and J. Robert (J. Appl. Phys. 44 (1973), 4869).

[0003] The work of J. Robert and F. Clerc (SID 80 Digest Techn. Papers (1980), 30), J. Duchene (Displays 7 (1986), 3), and H. Schad (SID 82 Digest Techn. Papers (1982), 244) has shown that liquid crystal phases must exhibit high values ​​for the ratio of the elastic constants K3 / K1, high values ​​for the optical anisotropy Δn, and values ​​for the dielectric anisotropy of Δε ≤ -0.5 in order to be used for highly informative display elements based on the ECB effect. Electro-optical display elements based on the ECB effect have a homeotropic edge orientation (VA technology = Vertically Aligned). Dielectrically negative liquid crystal media can also be used in displays that employ the so-called IPS or FFS effect. Displays that utilize the ECB effect have become known as VAN (Vertically Aligned Nematic) displays, for example in the MVA (Multi-Domain Vertical Alignment) form factor, e.g.: Yoshide, H. et al., Lecture 3.1: "MVA LCD for Notebook or Mobile PCs ...", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book I, pp. 6 to 9 and Liu, CT et al., Lecture 15.1: "A 46-inch TFT-LCD HDTV Technology ...", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 750 to 753), PVA (Patterned Vertical Alignment, e.g.: Kim, Sang Soo, Lecture 15.4: "Super PVA Sets New State-of-the-Art for LCD-TV", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 760 to 763), ASV- (Advanced Super View, e.g.: Shigeta, Mitzuhiro and Fukuoka, Hirofumi, Lecture 15.2: "Development of High Quality LCDTV", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 754 to 757) Displays, next to IPS (. In Plane Switching) (e.g., Yeo, SD, Lecture 15.3: "A LC Display for the TV Application", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book II, pp. 758 & 759) has established the long-established TN (Twisted Nematic) displays as one of the three most important new types of liquid crystal displays, especially for television applications. In general terms, the technologies are compared, for example, in Souk, Jun, SIDSeminar 2004, Seminar M-6: "Recent Advances in LCD Technology", Seminar Lecture Notes, M-6 / 1 to M-6 / 26 and Miller, Ian, SIDSeminar 2004, Seminar M-7: "LCD-Television", Seminar Lecture Notes, M-7 / 1 to M-7 / 32. Although the switching times of modern ECB displays have already been significantly improved by overdrive control methods, e.g.: Kim, Hyeon Kyeong et al., Lecture 9.1: "A 57-in. Wide UXGA TFT-LCD for HDTV Application", SID 2004 International Symposium, Digest of Technical Papers, XXXV, Book I, p.106 to 109, achieving video-compatible switching times, especially when switching between grayscale levels, is still a problem that has not been satisfactorily solved.

[0004] For the technical application of this effect in electro-optical display elements, FK phases are required that must meet a wide range of requirements. Particularly important are chemical resistance to moisture, air, and physical influences such as heat, radiation in the infrared, visible, and ultraviolet ranges, and static and alternating electric fields.

[0005] Furthermore, technically usable FK phases require a liquid crystalline mesophase in a suitable temperature range and a low viscosity.

[0006] None of the known series of compounds with liquid-crystalline mesophases has a single compound that meets all these requirements. Therefore, mixtures of two to 25, preferably three to 18, compounds are typically prepared to obtain substances suitable as liquid-crystalline phases. However, optimal phases could not be easily produced in this way, as no liquid crystal materials with significantly negative dielectric anisotropy and sufficient long-term stability were previously available.

[0007] Matrix liquid crystal displays (MCDs) are well-known. Nonlinear elements for individually switching the individual pixels can be, for example, active elements (i.e., transistors). This is then referred to as an "active matrix," and two types can be distinguished: 1. MOS (Metal Oxide Semiconductor) transistors on a silicon wafer as a substrate. 2. Thin-film transistors (TFT) on a glass plate as a substrate.

[0008] In Type 1 displays, the electro-optical effect typically used is dynamic scattering or the guest-host effect. The use of single-crystal silicon as the substrate material limits the display size, as the modular composition of different sub-displays also leads to problems at the joints.

[0009] In the more promising type 2, which is preferred, the TN effect is usually used as the electro-optical effect.

[0010] Two technologies are distinguished: TFTs made from compound semiconductors such as CdSe, and TFTs based on polycrystalline or amorphous silicon. The latter technology is the subject of intense research worldwide.

[0011] The TFT matrix is ​​applied to the inside of one glass plate of the display, while the other glass plate carries the transparent counter electrode on its inner surface. Compared to the size of the pixel electrode, the TFT is very small and hardly interferes with the image. This technology can also be extended to fully color-capable image displays, with a mosaic of red, green, and blue filters arranged so that each filter element is opposite a switchable pixel.

[0012] The term MFK displays here encompasses any matrix display with integrated non-linear elements, i.e., in addition to the active matrix, also displays with passive elements such as varistors or diodes (MIM = metal-insulator-metal).

[0013] Such MFK displays are particularly suitable for TV applications (e.g., pocket televisions) or for highly informative displays in automotive or aircraft manufacturing. Besides problems regarding the angle dependence of the contrast and switching times, MFK displays also suffer from difficulties due to an insufficiently high specific resistance of the liquid crystal mixtures [TOGASHI, S., SEKIGUCHI, K., TANABE, H., YAMAMOTO, E., SORIMACHI, K., TAJIMA, E., WATANABE, H., SHIMIZU, H., Proc. Eurodisplay 84, Sept. 1984: A 210-288 Matrix LCD Controlled by Double Stage Diode Rings, p. 141 ff, Paris; STROMER, M., Proc. Eurodisplay 84, Sept. 1984: Design of Thin Film Transistors for Matrix Addressing of Television Liquid Crystal Displays, p. 145 ff, Paris]. As resistance decreases, the contrast of an MFK display deteriorates.Since the specific resistance of the liquid crystal mixture generally decreases over the lifetime of an MFK display due to interaction with the internal surfaces of the display, a high (initial) resistance is very important for displays that must maintain acceptable resistance values ​​over a long operating period.

[0014] There is therefore still a great need for MFK displays with fast switching times, a wide operating temperature range, and low threshold voltage, which can be used to generate different shades of gray.

[0015] The disadvantage of the commonly used MFK-TN displays lies in their comparatively low contrast, the relatively high viewing angle dependency and the difficulty of generating grayscale levels in these displays.

[0016] VA displays offer significantly better viewing angle stability and are therefore primarily used for televisions and monitors. However, there is still a need to improve response times, especially for use in televisions with frame rates (refresh rates) above 60 Hz. At the same time, other properties such as low-temperature stability must not be compromised.

[0017] The invention is based on the objective of providing liquid crystal mixtures, particularly for monitor and TV applications based on the ECB, IPS, or FFS effect, that do not exhibit the aforementioned disadvantages or only to a lesser extent. In particular, it must be ensured that monitors and televisions operate even at extremely high and extremely low temperatures, while simultaneously exhibiting very low switching times and improved reliability, especially no or significantly reduced image sticking after extended operating times.

[0018] Liquid crystal media for IPS displays, for example, are described in EP 2 292 720 A1, EP 2 921 545 A2 or EP 2 657 318 A1.

[0019] Surprisingly, it is possible to reduce the ratio of rotational viscosity γ 1 and the elastic constant K 33 (γ 1 / K 33 ) and thus improve switching times by using the compound of formula I in liquid crystal mixtures, especially in LC mixtures with negative dielectric anisotropy, preferably for VA, IPS and FFS displays, and also for PM (passive matrix) VA displays.

[0020] Surprisingly, the compound of formula I exhibits both a very low rotational viscosity and a high absolute value of dielectric anisotropy. Therefore, liquid crystal mixtures, preferably VA, IPS, and FFS mixtures, can be produced that exhibit very low switching times, good phase properties, and good low-temperature behavior.

[0021] The invention thus relates to a liquid crystalline medium according to claim 1, which contains the compound of formula and additionally one or more biphenyls of formulas B-1 to B-4.

[0022] The mixtures according to the invention preferably exhibit very broad nematic phase ranges with clearing points ≥ 68 °C, preferably ≥ 70 °C, very favorable values ​​for the capacitive threshold, relatively high values ​​for the holding ratio, and simultaneously very good low-temperature stability at -20 °C and -30 °C, as well as low rotational viscosities and short switching times. The mixtures according to the invention are further characterized by the fact that, in addition to improving the rotational viscosity γ1, relatively high values ​​of the elastic constant K33 are observed, thus improving the switching times.

[0029] Another object of the invention is an electro-optical display with active matrix addressing based on the ECB, VA, PS-VA, PVA, PM-VA, SS-VA, IPS, PS-IPS, FFS effect, in particular UB-FFS, or PS-FFS effect, characterized in that it contains as a dielectric a liquid crystalline medium according to one or more of claims 1 to 14.

[0030] The liquid crystalline medium according to the invention preferably has a nematic phase from ≤ -20 °C to ≥ 70 °C, particularly preferably from ≤ -30 °C to ≥ 80 °C, and most preferably from ≤ -40 °C to ≥ 90 °C.

[0031] The term "exhibiting a nematic phase" here means, on the one hand, that at low temperatures, no smectic phase or crystallization is observed at the corresponding temperature, and on the other hand, that no clarification occurs upon heating from the nematic phase. The investigation at low temperatures is carried out in a flow viscometer at the corresponding temperature and verified by storage in test cells with a layer thickness appropriate to the electro-optical application for at least 100 hours. If the storage stability at a temperature of -20 °C in a suitable test cell is 1,000 h or more, the medium is considered stable at this temperature. At temperatures of -30 °C and -40 °C, the corresponding times are 500 h and 250 h, respectively. At high temperatures, the clarification point is measured in capillaries using standard methods.

[0032] Preferably, the liquid crystal mixture has a nematic phase range of at least 60 K and a flow viscosity v 20 of a maximum of 30 mm 2< . s -1< at 20 °C.

[0033] The values ​​of the birefringence Δn in the liquid crystal mixture are generally between 0.07 and 0.16, preferably between 0.08 and 0.13.

[0036] For the purposes of the present invention, the term "threshold voltage" refers to the capacitive threshold (V 0 ), also called the Freedericksz threshold, unless explicitly stated otherwise.

[0037] Furthermore, the liquid crystal media according to the invention exhibit high values ​​for the Voltage Holding Ratio in liquid crystal cells.

[0038] As a rule, liquid crystal media with a low drive voltage or threshold voltage exhibit a lower voltage holding ratio than those with a higher drive voltage or threshold voltage, and vice versa.

[0039] For the purposes of the present invention, the terms "dielectrically positive compounds" mean compounds with a Δε > 1.5, "dielectrically neutral compounds" mean those with -1.5 ≤ Δε ≤ 1.5, and "dielectrically negative" compounds mean those with Δε < -1.5. The dielectric anisotropy of the compounds is determined by dissolving 10% of the compounds in a liquid crystal host and measuring the capacitance of the resulting mixture in at least one test cell each with a 20 µm layer thickness, both with homeotropic and homogeneous surface orientations, at 1 kHz. The measurement voltage is typically 0.5 V to 1.0 V, but it is always lower than the capacitive threshold of the respective liquid crystal mixture under investigation.

[0040] All temperature values ​​given for the present invention are in °C.

[0041] The mixtures according to the invention are suitable for all VA-TFT applications, such as VAN, MVA, (S)-PVA, ASV, PSA (polymer sustained VA), SS (surface-stabilized)-VA and PS-VA (polymer stabilized VA). Furthermore, they are suitable for IPS ( I n plane switching) and FFS ( F rings f field switching), especially UB-FFS, with negative Δε suitable.

[0042] The nematic liquid crystal mixtures in the displays according to the invention generally contain two components A and B, which in turn consist of one or more individual compounds.

[0043] Component A exhibits a significantly negative dielectric anisotropy and imparts a dielectric anisotropy of ≤ -0.5 to the nematic phase. It preferably contains, in addition to one or more compounds of formula I, the compounds of formulas IIA, IIB and / or IIC, and also compounds of formula III.

[0044] The proportion of component A is preferably between 45 and 100%, particularly between 60 and 100%.

[0045] For component A, preferably one (or more) individual compound(s) is chosen that has a value of Δε ≤ -0.8. This value must be more negative the smaller the proportion of A in the total mixture.

[0046] Component B exhibits pronounced nematogenicity and a flow viscosity of no more than 30 mm²·s⁻¹, preferably no more than 25 mm²·s⁻¹, at 20 °C.

[0047] A wide variety of suitable materials are known to experts from the literature. Compounds of formula III are particularly preferred.

[0048] Particularly preferred individual compounds of component B are extremely low viscosity nematic liquid crystals with a flow viscosity of no more than 18, preferably no more than 12 mm²·s⁻¹ at 20 °C.

[0049] Component B is monotropic or enantiotropic nematic, exhibits no smectic phases, and can prevent the formation of smectic phases in liquid crystal mixtures down to very low temperatures. For example, if a smectic liquid crystal mixture is mixed with various materials of high nematogenousness, the nematogenousness of these materials can be compared by the degree of smectic phase suppression achieved.

[0050] Optionally, the mixture can also contain a component C, which is a compound with a dielectric anisotropy of Δε ≥ 1.5. These so-called positive compounds are typically present in a mixture with negative dielectric anisotropy in amounts of ≤ 20 wt.% of the total mixture.

[0051] If the mixture according to the invention contains one or more compounds with a dielectric anisotropy of Δε ≥1.5, these are preferably one or more compounds of formulas P-1 and / or P-2, wherein Straight-chain alkyl, alkoxy or alkenyl with 1 or 2 to 6 carbon atoms respectively, and XF, Cl, CF3, OCF3, OCHFCF3 or CCF2 CHFCF3, preferably F or OCF3 mean.

[0052] Preferably, the compounds P-1 and / or P-2 are used in concentrations of 0.5-10 wt.%, in particular 0.5-8 wt.%, in the mixtures according to the invention.

[0054] In addition, these liquid crystal phases can also contain more than 18 components, preferably 18 to 25 components.

[0055] Preferably, the phases contain, in addition to one or more compounds of formula I, 4 to 15, in particular 5 to 12, and particularly preferably < 10, compounds of formulas IIA, IIB and / or IIC and optionally III.

[0056] In addition to compounds of formula I and the compounds of formulas IIA, IIB and / or IIC and optionally III, other components may also be present, e.g. in an amount of up to 45% of the total mixture, preferably, however, up to 35%, in particular up to 10%.

[0057] The other components are preferably selected from the nematic or nematogenic substances, in particular the known substances, from the classes of azoxybenzenes, benzylidene anilines, biphenyls, terphenyls, phenyl or cyclohexyl benzoates, cyclohexane carboxylic acid phenyl or cyclohexyl esters, phenylcyclohexanes, cyclohexyl biphenyls, cyclohexylcyclohexanes, cyclohexylnaphthalenes, 1,4-bis-cyclohexyl biphenyls or cyclohexyl pyrimidines, phenyl or cyclohexyl dioxanes, optionally halogenated stilbenes, benzyl phenyl ethers, tolanes and substituted cinnamic acid esters.

[0058] The most important compounds that may be components of such liquid crystal phases can be characterized by formula IV, R 20< -LGER 21< IV, wherein L and E each represent a carbo- or heterocyclic ring system from the group formed from 1,4-disubstituted benzene and cyclohexane rings, 4,4'-disubstituted biphenyl, phenylcyclohexane and cyclohexylcyclohexane systems, 2,5-disubstituted pyrimidine and 1,3-dioxane rings, 2,6-disubstituted naphthalene, di- and tetrahydronaphthalene, quinazoline and tetrahydroquinazoline.

[0059] In most of these compounds, R20< and R21< are different, with one of these substituents usually being an alkyl or alkoxy group. Other variations of the intended substituents are also common. Many such substances, or mixtures thereof, are commercially available. All of these substances can be prepared using methods known from the literature.

[0060] It is self-evident to the person skilled in the art that the VA, IPS or FFS mixture according to the invention may also contain compounds in which, for example, H, N, O, Cl, F are replaced by the corresponding isotopes.

[0061] The mixtures according to the invention can further be supplemented with polymerizable compounds, so-called reactive mesogens (RMs), for example such as

[0062] Disclosed in US 6,861,107, these mixtures are added in concentrations preferably of 0.01 to 5 wt.%, particularly preferably 0.2 to 2% based on the mixture. Optionally, these mixtures can also contain an initiator, as described, for example, in US 6,781,665. The initiator, e.g., Irganox-1076 from BASF, is preferably added to the mixture containing polymerizable compounds in amounts of 0 to 1%. Such mixtures can be used for so-called Polymer Stabilized VA (PS-VA) or PSA (Polymer Sustained VA) modes, in which polymerization of the reactive mesogens is to take place in the liquid crystal mixture. A prerequisite for this is that the liquid crystal mixture itself does not contain any polymerizable components that would also polymerize under the conditions in which the compounds of formula M polymerize.

[0063] The polymerization is preferably carried out under the following conditions: The polymerizable components are polymerized in a cell using a UV-A lamp of defined intensity for a defined period and applied voltage (typically 10 to 30 V AC, frequencies in the range of 60 Hz to 1 kHz). A metal halide lamp or a high-pressure mercury lamp with an intensity of < 50 mW / cm² is typically used as the UV-A light source. These are conditions where, for example, liquid crystalline compounds with an alkenyl or alkenyloxy side chain, such as the compounds of the formula [formula missing in original text], are suitable for polymerization. polymerize with n = 2, 3, 4, 5 or 6.
