Description
本發明係有關於一種影像顯示系統，特別是關於一種具有液晶顯示裝置的影像顯示系統。The present invention relates to an image display system, and more particularly to an image display system having a liquid crystal display device.
液晶顯示裝置利用薄型、輕量及低電力消耗之特長，而應用於範圍較廣之領域中。液晶顯示裝置可具備一對基板，基板上設置電極且基板間設置一液晶層，當對設置於基板上的電極適當地施加電壓時，可控制液晶層中所含有之液晶分子的旋轉方向。液晶顯示裝置通常具有設置於基板之液晶層側之表面的液晶配向膜以控制液晶分子之配向方向。The liquid crystal display device is used in a wide range of fields by utilizing the advantages of thinness, light weight, and low power consumption. The liquid crystal display device may include a pair of substrates, and an electrode is provided on the substrate, and a liquid crystal layer is provided between the substrates. When a voltage is appropriately applied to the electrodes provided on the substrate, the rotation direction of the liquid crystal molecules contained in the liquid crystal layer can be controlled. The liquid crystal display device usually has a liquid crystal alignment film provided on the surface of the liquid crystal layer side of the substrate to control the alignment direction of the liquid crystal molecules.
液晶配向膜主要是由聚合材料製成。液晶配向膜扮演導引液晶分子之引向器。當藉由電場之影響移動液晶分子以呈現影像時，液晶配向膜使這些分子在預定方向上定向。一般而言，需要均勻配向液晶分子以便為液晶裝置提供均勻亮度以及高對比率。The liquid crystal alignment film is mainly made of a polymeric material. The liquid crystal alignment film acts as a director for guiding the liquid crystal molecules. When the liquid crystal molecules are moved by the influence of the electric field to present an image, the liquid crystal alignment film orients the molecules in a predetermined direction. In general, it is necessary to uniformly align liquid crystal molecules in order to provide uniform brightness and high contrast ratio to the liquid crystal device.
配向液晶之習知方法包含將諸如聚醯亞胺(polyimide)之聚合物膜塗覆於玻璃基板上，以及用諸如尼龍(nylon)或聚酯之纖維(polyester)在某一方向上摩擦基板之表面。然而，摩擦方法在利用纖維摩擦聚合物膜時所產生之粉塵或靜電放電(electrostatic discharge，ESD)而引起嚴重問題。Conventional methods for aligning liquid crystals include coating a polymer film such as polyimide on a glass substrate, and rubbing the surface of the substrate in a certain direction with a polyester such as nylon or polyester. . However, the rubbing method causes serious problems in dust or electrostatic discharge (ESD) generated when the fiber is rubbed against the polymer film.
為了解決摩擦方法引起之問題，近來業界已研究光輻射配向方法(簡稱光配向)，藉由在膜上照射光來誘導聚合物膜之各向異性，以便將液晶分子配向。已提出之光配向方法係利用具有光官能基之聚合物作為配向膜材料。藉由用偏振光照射使這些聚合物各向異性地光異構化、光交聯或光裂解，以便對表面提供各向異性，從而使其能夠誘導液晶分子在某一方向上配向。In order to solve the problems caused by the rubbing method, the optical radiation alignment method (referred to as photoalignment) has recently been studied in the industry, and the anisotropy of the polymer film is induced by irradiating light on the film to align the liquid crystal molecules. A photoalignment method has been proposed which utilizes a polymer having a photofunctional group as an alignment film material. These polymers are anisotropically photoisomerized, photocrosslinked, or photolyzed by irradiation with polarized light to provide anisotropy to the surface, thereby enabling it to induce alignment of the liquid crystal molecules in a certain direction.
用於液晶配向膜之材料應具有光學穩定性及熱穩定性，以便使其適用於液晶顯示裝置。然而，就此點而言，習知光配向材料所形成之配向膜光學穩定性及熱穩定性不佳，導致配向力不穩定。此外，一般來說，光配向處理法所形成之配向膜其錨定能小於利用摩擦法所形成之配向膜，如此一來會導致回應速度(response speed)的下降或是造成影像留痕。The material used for the liquid crystal alignment film should have optical stability and thermal stability so as to be suitable for use in a liquid crystal display device. However, in this regard, the alignment film formed by the conventional light alignment material has poor optical stability and thermal stability, resulting in unstable alignment force. In addition, in general, the alignment film formed by the photo-alignment processing method has an anchoring energy smaller than that of the alignment film formed by the rubbing method, which may cause a decrease in the response speed or cause image sticking.
基於上述，目前業界亟需一種新穎的光配向方法，來形成具有高穩定性及錨定效果的配向膜，來解決習知技術所目臨的問題。Based on the above, there is a need in the industry for a novel photo-alignment method to form an alignment film having high stability and anchoring effect to solve the problems posed by the prior art.
有鑑於此，本發明提供一種具有液晶顯示裝置之影像顯示系統，其具有改良的光異構化配向層，與傳統光異構化配向法相比，具有較高的配向效果及光學穩定性。此外，本發明亦提供一種影像顯示系統的製造方法，可減少光異構化高分子層的照光時間，並增加配向膜穩定性及錨定效果，達到降低成本以及提高產能的目的。In view of the above, the present invention provides an image display system having a liquid crystal display device, which has an improved photoisomerization alignment layer, which has higher alignment effect and optical stability than the conventional photo isomerization alignment method. In addition, the present invention also provides a method for manufacturing an image display system, which can reduce the illumination time of the photoisomerization polymer layer, increase the stability and anchoring effect of the alignment film, and achieve the purpose of reducing cost and increasing productivity.

The method for manufacturing the liquid crystal display device may include the following steps: first, providing an upper substrate and a lower substrate, wherein the method The upper substrate and the lower substrate are disposed in parallel with each other (step 101). Next, a first photoisomerization polymer layer is coated on the lower surface of the upper substrate, and a second photoisomerization polymer layer is coated on the upper surface of the lower substrate (step 102). The photoisomerized polymer may be an azo polymer such as an aromatic azo polymer. For example, the photoisomerization polymer can be formed by polymerization of an azobenzene monomer having an acrylate group, wherein the azobenzene monomer having an acrylate group can be used. For example, it has the following structure: (wherein R 1 is hydrogen or C 1-6 alkyl). Next, after the coating of the photoisomerization polymer layer is completed, a first energy is applied to the first photoisomerization polymer layer and the second photoisomerization polymer layer to form a first energy The first photoisomerization alignment layer and a second photoisomerization alignment layer (step 103).

When the weight percentage of the non-polar monomer is less than 0.05% by weight, the problem of insufficient photo-alignment ability may be caused; and when the weight percentage of the non-polar monomer is more than 3% by weight, excessive non-polar monomers may cause alignment of the liquid crystal molecules. Disorder. Further, the liquid crystal composition may be injected into a One Drop Filling (ODF) process. Finally, after injecting the liquid crystal composition, the liquid crystal composition is subjected to a second energy (step 105) to polymerize the non-polar monomer in the liquid crystal composition and adhere to the first photo-isomerization. The alignment layer and the second photoisomerization alignment layer are formed with a plurality of protrusions on the surface of the first photoisomerization alignment layer and the second photo isomerization alignment layer to obtain the liquid crystal display device. The second energy may be ultraviolet light having a wavelength of 310-400 nm (which may be general UV light or linear polarized light), and the time for applying the second energy to the liquid crystal composition may be 100-1800 seconds, and the illuminance may be between 5~10mW, and the total exposure can be 0.5J~18J.
