Description

V. Description of the invention (1) Field of invention:

This article is about a kind of polarizer and a polarizing system, especially about using a large-sized polarizer and a polarizing system. Conventional technical description: Generally σ 'Liquid Crystal Display Device' (abbreviated as LCD) is formed by filling a liquid crystal between substrates facing the upper and lower layers. The upper and lower substrates have electrodes and a specific pattern to be displayed on the substrate surface. There is an alignment layer between the electrodes so that the LCD can be implanted at a tilt angle. To calibrate the alignment layer, a rubbing method photo-alignment method or the like can be used. The polishing method is to place an alignment material on the substrate, such as polyshang ^ Asia〗 ^ polyimide (PI), and rub the substrate with a rubbing cloth to implant in the liquid crystal—

Inclination. Using this method, a large-size liquid crystal display can be manufactured and the alignment layer D can be calibrated very quickly. However, during the above-mentioned friction process, microgrooves defects will be generated in the alignment layer. These microgrooves will cause Light scattering and light phase are randomly distorted (distortin). In addition, dust particles and electrostatic charges will be generated on the alignment layer, so that thin filE transistors on the substrate will be damaged, which will reduce production benefits.

d453 8 1 5 'Explanation of the invention (2) Another light alignment method uses ultraviolet rays to irradiate a substrate with a light alignment layer to implant a tilt angle in the liquid crystal. Compared with the friction method, this light alignment method has no dust particles and electrostatic charges, which can avoid the problem of reduced production benefits. Moreover, this light alignment method can simultaneously control the inclination angle on this alignment layer, and evenly arrange the molecules of the liquid crystal. Therefore, the light alignment method has many advantages, including preventing light from being randomly distorted or light scattering caused by micro grooves. At this time, a 'light polarizer' polarizes the light to obtain linearly or partially polarized ultraviolet light. In particular, 'The characteristics of this optical polarizer are as large as possible' is the use of the ultraviolet wavelength band, so that it has the ability to withstand high temperature and high light transmittance < = However, 'the conventional polarizer is smaller in size' is more difficult to respond The light alignment method of the display is in process. At the same time, from the recognition of V and J, the durability of the optical polarizer due to the addition of the South polymer (polymer) and the deterioration of the high temperature resistance, and the wavelength of the incident light are reduced, resulting in durability. Summary of the invention: The purpose is to display on large LCDs. Provide a large-sized polarizer to ensure uniform light alignment process. Another object of the present invention is to provide-polarized "moonlight to simplify the process and drive the polarizer, including other large-sized polarizers. The purpose and advantages will be part of the system. And, part will be learned from the implementation of the present invention.

In Figs. 2B and 2C, Θ represents the vertical normal vector of the quartz substrate portion 1 and the central angle of the incident light. The Brewster θB angle at this time is described below. When the polarized light irradiates the Brewster (b) angle of the incident light under the quartz substrate portion 1, the vibration direction of the electric field vector of the reflected light is perpendicular to the incident surface, and is linearly polarized. The transmitted light is partially polarized ^!

As described above, when the incident light can be linearly polarized to obtain a linear polarization or part, Fig. 4A is a large-size polarizer of the present invention, "square" and the polarizer quartz substrate part 15. Each quartz substrate is polarized in line with the incident light.

Compared with the polarizer, the fixed-inch LCD monitor has a large size. The cutting line of the polarizer I-11 The quartz substrate portion 15 is a multi-layered quartz substrate portion transmitted by the incident light with the surface of a Bruce straight holder 1 3. The light is a linearly polarized angle ΘB, and the transmitted light is only P-polarized light. Ip shows that the light reflected from the multi-layered quartz substrate portion n is also transparent when the number of layers of the quartz substrate portion whose reflected light is only s-polarized at a Brewster angle ΘB exceeds a certain number. Therefore, the layers of the quartz substrate portion are controlled. The polarized transmitted light can be divided into several numbers.

The material included in the holder 13 transmitted through the semi-permanent quartz substrate portion 15 and the plate portion 15. The quartz substrate portion 1 5 is a large-scale substance of the present invention which requires a certain number of layers of light by the light alignment method. The reflective part of the part can be obtained by the number of layers of the radiation-level receiver. The multi-layer part can use a polarizer with a durability of 15 compared to the normal angle of the holder. 3. The beam is split at an unpolarized parallel incidence. It will be absorbed by the holder 1 3; it will be incident on the calibration layer 50 (see FIG. 5A) and preferably includes a light absorption ratio on the large-size polarizer 10 to obtain the required degree of polarization. To obtain linear polarization, the quartz substrate needs Shiyang substrate section. If you only want to obtain a single layer or any number of quartz-based substrates, and the conventional polarizer does not choose an absorption mode, you can choose it without wavelength dependence. As shown in Figure 4B, for the large-size polarizer 1 〇, due to fixed ^ 丨, the position of the calibration layer 50 is not uniform for the transmitted light of the large-sized polarizer.

The substrate phase 5 疋 is composed of—or a multi-layered quartz substrate portion, and the stone substrate portions are connected in one direction. Based on the above-mentioned angular-shaped composition structure, the large-sized polarizer 100 Kossa scans along the X axis to obtain uniform illumination. For example, although scanning along the χ axis: L length, the illumination effect of the edge of the quartz substrate portion (area bounded by the width in 圊 6) is equally obtained over the entire area, and because the fixture 10 is not light-lit, The area is also uniformly covered.

For example, although the length “L” along the X-axis is obtained equally over the entire area of the quartz substrate, the lighting effect of the invention description (9) (the area with the width W in FIG. 6), and The area illuminated by radiation is evenly covered. In addition, compared with the triangular quartz substrate portion 105 in FIG. 6, the quartz substrate portion 11 5 in a parallelogram structure is easier to set. 8 The large-sized polarizers in FIG. 6 and FIG. 7 are used. The light emitted from the light source 7 is reflected by the cold mirror 61 to the small-sized polarizer 20, focused by the fly-eye lens 31, and transmitted through another small-sized polarizer 40. The light is reflected by a mirror 63 to a collimating lens 30. After collimating and focusing, the light becomes unpolarized parallel light. This unpolarized parallel light enters a quartz substrate portion of a large-size polarizer 100 (or 110) (see Figs. 6 and 7) placed at a Brewster ΘB angle. A part of the light is reflected and a part of the light is transmitted through a mask 80 and then radiated on the base 75 to the calibration layer 50 on the substrate 70.
