Description
Technical field
The present invention is particularly to a kind of single layer optical film that has polarisation and orientation function concurrently that is applied to LCD relevant for a kind of monolayer polarizing and orientation function conformity membrane.
Background technology
Flat liquid crystal display extensively is applied to every hyundai electronics product, as personal computer, notebook, digital camera, mobile phone, individual digital assistant (PDA) and LCD TV etc.Traditional LCD as shown in Figure 6, comprise a pair of upper and lower light polarizing film 103,104, be located at the outside of upper substrate 101 and infrabasal plate 102 respectively, 105,106 of alignment films are arranged between the upper and lower base plate, folder is established liquid crystal layer 110, makes liquid crystal molecule regularly arranged.
Light polarizing film is the optical module that a kind of natural light of will not have polarization characteristic is transformed into the polarisation with polarization characteristic, and it has many usability on industry, for example is applied on the LCD, and light polarizing film shows on the effectiveness at it plays the part of critical role.In addition, light polarizing film also can be used for optical mirror slip, and for example: the polariscope of camera, snowfield all have great commercial exploitation with glasses or the like.
Traditional light polarizing film manufacture method; the method that disclosed for No. 2237567 and No. 2454515 of United States Patent (USP) for example; it utilizes high-molecular organic materials such as polyvinyl alcohol (PVA) (PVA) or derivatives thereof absorption iodine and makes 3～5 times of uniaxial tensions; to cause wherein optical anisotropy composition for example to contain the crystal generation rule arrangement of I; make the light inject light polarizing film be absorbed and produce polarisation at the electric-field vector of certain specific direction; yet this light polarizing film is not good to the anti-patience of envirment factors such as moisture and heat; therefore can't under hot and humid environment, use; and this polaroid diaphragm of generally still needing; as the protection of Triafol T (TAC) film, and this suitable TAC film is difficult for obtaining.In addition, this method for making needs very accurate drawing process, and is very inconvenient in the making.
Another kind of dyestuff is light polarizing film then has preferred moisture and heat compared to iodine polarizing film an anti-patience, but its shortcoming is the injury that degree of polarization is lower and be easy to be subjected to UV light and mechanical friction, simultaneously it utilizes that impregnation, heating, multiple tracks are accurate to stretch and multiple tracks technologies such as applying are made, during production costs and complexity.
In addition, when making LCD, also need to do liquid crystal molecule regularly arranged according to design, traditional alignment technique is brushing orientation (rubbing process) method, but this method is in brushing technology, and it all is the disappearance that is difficult to overcome that the dirt bits that friction film caused pollute (dust), static residual (static charge), brush mark defective (rubbingdefect) etc.In addition, currently used alignment materials is the polyimide series macromolecular, it can be divided into polyamic acid (polyamic acid) and soluble polyimide (soluble PI) two classes, the former toasts for a long time with high temperature in technology, be cracked into micromolecule during preservation easily, long preservation is not good; Therefore the latter is insoluble in the common organic solvents usually because polyimide has been state of polymer, and coating is not easy regulation and control, and synthetic difficulty is higher, will face the predicament that can't overcome so make LCD alignment in a conventional manner.
Single blooming can't satisfy the demand of display to all characteristics of light, therefore often need other various blooming of collocation, in LCD, in order to reach the demonstration purpose, several membranes materials such as light polarizing film, alignment film on need in substrate, inserting or be coated with, except that must establishing the multiple film material of produce in factory in addition, also need multiple tracks technology just can finish, quite complicated on technology.
Therefore, industry is needed a kind of multi-functional conformability film of individual layer badly, to improve the shortcoming that needs to use multiple film material in traditional liquid crystal display.
