Description

具有高穿透率的液晶組合物及其顯示器件 Liquid crystal composition with high transmittance and display device thereof

本發明涉及一種液晶組合物,特別涉及一種電光學目的的用途液晶組合物以及包含該液晶組合物的液晶顯示器,特別涉及包含該液晶組合物有源矩陣定址的顯示器和平面內切換(IPS)類型的顯示器。 The present invention relates to a liquid crystal composition, and more particularly to a liquid crystal composition for electro-optical purposes and a liquid crystal display comprising the liquid crystal composition, and more particularly to a display and an in-plane switching (IPS) type including active matrix addressing of the liquid crystal composition. Display.

液晶顯示器(Liquid Crystal Display,LCD)因其體積小、重量輕、功耗低且顯示品質優異而獲得了飛速發展,特別在可擕式電子資訊產品中獲得廣泛的應用。隨著用於可擕式電腦、辦公應用、視頻應用的液晶螢幕尺寸的增加,為了使液晶顯示器能夠用於大螢幕顯示並最終替代了陰極射線管的顯示器(Cathode Ray Tube,CRT),還有幾個問題需要解決。如改善視角特性和提高回應速度等。LCD的視角比較窄是指在離開垂直於液晶盒法線方向觀察時,對比度明顯下降,對於灰度和彩色顯示,視角大時還會發生灰度和彩色反轉的現象,嚴重影響了LCD的顯示品質。視角問題成為LCD替代CRT技術的一大障礙。 Liquid crystal displays (LCDs) have achieved rapid development due to their small size, light weight, low power consumption and excellent display quality, especially in portable electronic information products. With the increase in the size of LCD screens for portable computers, office applications, and video applications, in order to enable liquid crystal displays to be used for large screen displays and eventually replace cathode ray tube displays (Cathode Ray Tubes, CRTs), Several issues need to be resolved. Such as improving the viewing angle characteristics and improving the response speed. The narrow viewing angle of the LCD means that the contrast is significantly reduced when viewed away from the normal direction of the liquid crystal cell. For grayscale and color display, grayscale and color inversion occur when the viewing angle is large, which seriously affects the LCD. Display quality. The perspective problem has become a major obstacle to LCD replacement of CRT technology.

LCD的視角問題是由液晶的工作原理本身決定的。液晶分子是棒狀的,不同的分子排列方式對應著不同的光學各向異性。入射光和液晶分子夾角越小,雙折射率就越小;反之雙折射率就越大。偏離顯示幕法線方向以不同的角度入射到液晶盒的光線與液晶分子指向矢的夾角不同,因此造成不同視角下,有效光程差△n*d不同。而液晶盒的最佳光程差 是按照垂直於盒的法線方向設計的,對於斜入射的光線,最小透射率隨夾角的增大而增大,對比度就會下降。當夾角足夠大時,甚至會出現對比度反轉的現象。 The viewing angle problem of the LCD is determined by the working principle of the liquid crystal itself. The liquid crystal molecules are rod-shaped, and different molecular arrangements correspond to different optical anisotropies. The smaller the angle between the incident light and the liquid crystal molecules, the smaller the birefringence; on the contrary, the greater the birefringence. The angle between the light incident on the liquid crystal cell at different angles from the normal direction of the display screen is different from the director of the liquid crystal molecules, so that the effective optical path difference Δn*d is different at different viewing angles. And the best optical path difference of the liquid crystal cell It is designed to be perpendicular to the normal direction of the box. For obliquely incident light, the minimum transmittance increases with the increase of the angle, and the contrast decreases. When the angle is large enough, even the contrast inversion occurs.

目前,已經提出了很多種解決視角問題的方法如:光學補償彎曲(Optically Compensated Bend,OCB)模式、共面轉換模式(In-Plane Switching,IPS)、邊緣場開關模式(Free Fall Sensor,FFS)和多疇垂面排列模式(Multi-Domain Vertical Alignment,MVA)等。 At present, many methods for solving perspective problems have been proposed, such as: Optically Compensated Bend (OCB) mode, In-Plane Switching (IPS), and Free Fall Sensor (FFS). And Multi-Domain Vertical Alignment (MVA).

它們都有各自的優缺點,多疇垂面排列模式具有高對比和快速回應的特點,但是它需要一個雙軸補償膜和兩個橢圓偏振片,因此成本較高,OCB模式很難用交流電壓來保持穩定控制,對R、G、B三種單色光的穿透率不一樣,另外在無場的情況下,液晶盒內的分子是按平行於基板的方向排列的,為了實現彎曲排列,需在盒上加幾秒電壓進行預置,然後可以在較低的電壓下維持這種排列方式,這對使用帶來不便。共面轉換模式僅需要線偏振片而不需要補償膜,只是它的回應速度太慢,不能顯示快速運動的畫面。由於IPS模式和FFS模式的製作簡單並且有很寬的視角,它們成了能夠改善視角特性並實現大面積顯示的最有吸引力的辦法。 They all have their own advantages and disadvantages. The multi-domain vertical arrangement mode has high contrast and fast response characteristics, but it requires a two-axis compensation film and two ellipses, so the cost is high, and the OCB mode is difficult to use AC voltage. In order to maintain stable control, the transmittances of three kinds of monochromatic lights of R, G, and B are different. In addition, in the absence of field, the molecules in the liquid crystal cell are arranged in a direction parallel to the substrate, in order to achieve a curved arrangement, It takes a few seconds to pre-set the voltage on the box, and then this arrangement can be maintained at a lower voltage, which is inconvenient for use. The coplanar conversion mode requires only a linear polarizer without the need for a compensation film, but its response speed is too slow to display a fast moving picture. Since the IPS mode and the FFS mode are simple to manufacture and have a wide viewing angle, they are the most attractive way to improve the viewing angle characteristics and achieve large-area display.

上世紀70年代初,已經對均勻排列的和扭曲排列的、向列液晶IPS模式的基本的電光特性進行了實驗性的研究,其特點是一對電極3製作在同一基板2上,而另一個基板2上沒有電極3,通過加在這一電極3間的橫向電場5來控制液晶分子4的排列,因此也可以稱這種模式為橫向場模式。在IPS模式中向列液晶分子4在兩基板2間均勻平行排列,兩偏振片1正交放置。其顯示原理如圖1所示,IPS模式在不加電場5時,入射 光被兩個正交的偏振片1阻斷而呈暗態。如圖2所示,加電場5時液晶分子4發生轉動造成延遲,於是光從兩個正交的偏振片1射出。 In the early 1970s, experimental studies were conducted on the basic electro-optical properties of uniformly aligned and twisted, nematic liquid crystal IPS modes, characterized in that a pair of electrodes 3 were fabricated on the same substrate 2, and the other There is no electrode 3 on the substrate 2, and the arrangement of the liquid crystal molecules 4 is controlled by the transverse electric field 5 applied between the electrodes 3. Therefore, this mode can also be referred to as a transverse field mode. In the IPS mode, the nematic liquid crystal molecules 4 are uniformly arranged in parallel between the two substrates 2, and the two polarizing plates 1 are placed orthogonally. The display principle is shown in Figure 1. The IPS mode is incident when no electric field is applied. The light is blocked by two orthogonal polarizing plates 1 to be in a dark state. As shown in FIG. 2, when the electric field 5 is applied, the liquid crystal molecules 4 are rotated to cause a delay, and thus light is emitted from the two orthogonal polarizing plates 1.

IPS模式可以使用正性液晶或負性液晶,因為透光率飽和電壓隨△ε的絕對值的增大而減小,所以正性液晶的透光率飽和電壓要比負性液晶的低,並且響應速度更快,但是負性液晶要比正性液晶的透光率要好些。原因如圖3和圖4所示,主要是由於正負液晶在電場下的轉動不同所致。 The IPS mode may use a positive liquid crystal or a negative liquid crystal because the transmittance saturation voltage decreases as the absolute value of Δε increases, so the transmittance saturation voltage of the positive liquid crystal is lower than that of the negative liquid crystal, and The response speed is faster, but the negative liquid crystal is better than the positive liquid crystal. The reason is shown in Fig. 3 and Fig. 4, mainly due to the difference in the rotation of the positive and negative liquid crystals under the electric field.

三星電子在2008年2月20日申請的專利CN101270287A曾經公開過一種正負性液晶混配的方案,但是只是提到在負性液晶中加入正性成分,液晶整體仍然為負性。智索株式会社在2000年11月21日申請專利JP2002156619A中也曾經公開過一種正負液晶混配的實驗方案,以上兩個方案均沒有詳細提到正性液晶中參雜少量負性液晶單體對IPS液晶顯示的穿透率的提升效果。 The patent CN101270287A, which was applied by Samsung Electronics on February 20, 2008, has disclosed a scheme of positive and negative liquid crystal compounding, but only mentions that a positive component is added to the negative liquid crystal, and the liquid crystal as a whole is still negative. Chisso Co., Ltd. also disclosed an experimental scheme for positive and negative liquid crystal compounding in the patent application JP2002156619A on November 21, 2000. The above two schemes do not mention in detail the small amount of negative liquid crystal monomer pairs in the positive liquid crystal. The improvement of the transmittance of the IPS liquid crystal display.

本發明的目的是提供一種應用於IPS模式中的液晶組合物,所述液晶組合物將一種或者多種負性液晶單體參雜在正介電各向異性的IPS液晶中,令人驚奇的發現,通過此種參雜模式,能夠在維持△ε不變的情況下,增大液晶的ε和ε,其中△ε=ε,△ε為介電各向異性,ε為平行於分子軸方向上的介電常數,ε為垂直於分子軸方向上的介電常數,△ε>0的液晶稱為正性液晶,△ε<0的液晶稱為負性液晶。 It is an object of the present invention to provide a liquid crystal composition for use in an IPS mode in which one or more negative liquid crystal monomers are doped in a positive dielectric anisotropic IPS liquid crystal, surprisingly found Through this doping mode, ε and ε 液晶 of the liquid crystal can be increased while maintaining Δ ε , where Δ ε = ε - ε , Δ ε is dielectric anisotropy, ε In order to be parallel to the dielectric constant in the molecular axis direction, ε is a dielectric constant perpendicular to the molecular axis direction, a liquid crystal having Δ ε>0 is referred to as a positive liquid crystal, and a liquid crystal having Δ ε<0 is referred to as a negative liquid crystal.

根據IPS模式的穿透率公式transmittance(穿透率)△ε/ε(“□”表示“反比例”關係)。通過將上述負性液晶單體摻雜正介電各向 異性的IPS液晶中,可以使得到的液晶組合物在保持正性IPS液晶的快響應,低驅動電壓、較高的清亮點、較低的旋轉黏度、合適的光學各向異性以及合適的介電各向異性等優點的同時,還極大地提高液晶顯示的穿透率,與現有的正介電各向異性的IPS液晶相比穿透率可提高5~20%。 Transmittance formula based on IPS mode. Transmittance △ ε / ε ("□" means "inverse proportion" relationship). By doping the above negative liquid crystal monomer into the positive dielectric anisotropy IPS liquid crystal, the obtained liquid crystal composition can maintain a fast response of the positive IPS liquid crystal, a low driving voltage, a high clearing point, and a low The rotational viscosity, suitable optical anisotropy, and suitable dielectric anisotropy, while greatly improving the transmittance of the liquid crystal display, and penetrating compared with the existing positive dielectric anisotropic IPS liquid crystal. The rate can be increased by 5~20%.
