Description

201027124 VI. Description of the invention: [Technical field to which the invention pertains] Field of the invention The present invention relates to a liquid helium display device capable of achieving high-speed response of hundreds of "S" levels. The present invention further relates to a type of lens including a display gradation domain, and the above-mentioned high-speed response speed is a constant high-speed liquid, a switchable S- and opaque glasses, and a control device thereof. And a liquid crystal display device capable of selectively viewing one of a stereoscopic image and a plurality of different images. [Former Technology] 3 Invented Background In recent years, especially in North America, 3D movies have been produced and publicly displayed. Can be viewed in the electrical view 3!) _ _ use the projector as a ejector to interactively project the right eye image and the left eye image, and make the projected light transmission using the liquid crystal and polarizing plate parts, *Electricity switching of liquid crystal parts 1±When switching the projector to project the right (four) image and projecting the left-eye image, the light is projected to form a different polarization state, and then the glare is projected, accompanied by polarized light. The glasses can be viewed by viewing the projection images for the right and left eyes. In the future, '3D movies will become more popular, and the demand for home entertainment is the same as that of the 2D movies to date. Under the generally established trend, 3D display devices that meet the requirements of home TV are needed. The system using the projector as in the above-mentioned cinema is particularly limited in setting environment for the home TV, so the title page realizes 3D display with the liquid crystal 201027124 crystal display of the current home TV. In addition, in recent years, home video game consoles have become widely popular. Among them, the game-oriented games are viewed from the individual viewpoints of the players. The focus is on improving the realism and the sense of presence. In fact, the display area of the display is divided and displayed. Or use a plurality of displays in a playground or the like to display a plurality of different views, but the former has a problem that the size of each screen is too small and the interference of adjacent images cannot be avoided, and the latter has to prepare a plurality of displays and is not suitable for Family problems. Therefore, it is necessary to realize a display device that can view different images without dividing a television screen. Heretofore, the 3D display device is known to be capable of interactively switching between displaying the right-eye image and the left-eye image on the CRT display, and using the optical shutter glasses that can be switched between the transparent and the opaque light in synchronization with the right eye. When the image is used, only the optical shutter for the right eye is in a light-transmissive state, and only the right-eye image is viewed with the right eye, and when the left-eye image is displayed, only the left-eye optical shutter is transparent, and only A display device for 3D imaging is realized by viewing the image for the left eye with the left eye (see Patent Document 1 and Patent Document 2). Further, a conventional 3D display device using a liquid crystal display has an optical element disposed in front of the liquid crystal panel in a state in which polarized light emitted through the liquid crystal panel is changed in each line or point of the liquid crystal panel, and includes a polarization direction and The polarized optical lens in which the polarization axes of the optical elements changed are the same. It displays the image for the right eye on an odd-numbered line of the liquid crystal panel, and displays the image for the left eye on the even-numbered line, and changes the polarization state by the optical element to the polarized light emitted by the odd-numbered line of the liquid crystal panel and the even-numbered line 201027124 The polarized light that is emitted, and the right-eye image of the odd-numbered line is viewed only by the right eye, and the left-eye image of the even-numbered line is viewed only by the left eye, by using the polarized glasses of the polarization wheel that has been changed by the optical element. The 3D image is realized (see Patent Document 3, Patent Document 4, and Patent Document 5). However, the above-described method of using a CRT display and an optical shutter glasses, because of the use of a CRT, makes it difficult to increase the face of the 3D image, and is also popular in recent years. In addition, the disclosures of the above-mentioned reference patent documents 1 and 2 do not limit the display to a cRT, but also a liquid crystal display, but currently the active matrix LCD system composed of a large direct-view amorphous germanium film (TFT) or the like is in line sequence. Since the image is updated, it is difficult to achieve a high-speed facet switching required for clearly distinguishing between the right-eye and left-eye images, and it is not possible to ensure a good 3D image during the display of the necessary fixed display image, which is a problem. Moreover, the method of using the optical element and the polarized glasses for changing the polarization state of each line or point of the liquid crystal display as described above is for the right eye and the neon image of each line or ❿, so the image read degree Only half of it is a big problem. As described above, a two-dimensional image forming apparatus capable of high-speed image switching, such as a CRT or a PDP, is generally more capable of high-speed image switching than an LCD, and since the image is emitted, the image is usually formed without random polarization or specific. Linear polarization first. Therefore, even if the light-emitting type is used, the brightness of the face can be kept high. If the active optical shutter is used to switch the linearly polarized light, at least half of the light of the facet = will not be transmitted to the eye to become the actual image display. Light utilization efficiency is not good. In this regard, the LCDS generally emits linearly polarized light from the 201027124 light source, so that the integrated light utilization efficiency of the active optical shutter that can switch linearly polarized light is better, which is an advantage. However, conventional LCDs are slow in important image update time, so even if the light efficiency is not good, a CRT, PDP or the like of a light-emitting type is often used as a two-dimensional image forming apparatus.

Embodiment 3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described with reference to the drawings as needed. In the following description, the representative ratios of “parts” and “%” are quality standards unless otherwise indicated. (Screen Update of LCD) Before explaining the technical contents of the present invention, a clear definition of the screen update of the LCD of the present invention which is extremely important to the concept of 201027124 will be performed. The update cycle of the display screen is expressed in units of the time to update and display one image, and is called the "screen update cycle". The scanning system updates the display data in the order of the screen as a whole. In one example, when the number of lines of the screen is 240 lines, the time from the 1 line scan to the 240 line is the "scanning time of the entire liquid crystal panel". The time from the start of the 240-line data update (scanning) to the display of the new screen before the start of the new scan is the "picture update period". The time from the start of the "scanning" of the update screen to the display of the next new image, the time during which the display is continued by the charge holding operation of the LCD after the scanning, that is, the "picture update period". In the range of the "picture update period" of one cycle, it is not limited to scanning only the entire screen. It also includes performing multiple scans in the "picture update period" of one cycle without changing the image data (in the same image data). When a uniform fixed screen is displayed after one image, the time for displaying a uniform fixed screen is also included in the "screen update period". "Uniform fixed screen" means that the image data of the same value constitutes the whole picture. An example of this is an image filled with fixed-value data such as "white", "black", and "gray of the same color". The specific display method is to display the "screen update period" of "the display time of the right eye image + the display time of the full black image" when the full-eye image is displayed and the screen is displayed as "black". Two full-screen scans are performed with the same image data, and the third image scan time (before the start of the next new image scan) is the "screen update cycle" when the black image is displayed for the third time. . Furthermore, in fact, one screen is divided into two regions, or divided into three regions or more, and as shown in the first and fourth graphs, when two regions are divided or divided into three regions and are driven by 10 201027124 rows, the driver is not driven. The line is divided into the display signal of the screen amount, and the time for displaying the screen is the screen update time. (Mechanism of 3D image display) The present invention implements the following two basic conditions by using the image for the right eye and the image for the left image as the basic two-time image. This is a high-speed response to the supply of charge to the pixel electrode of the liquid crystal as a load capacitor (high-speed charging of the TFT, giving the potential for driving the liquid crystal), and the high-speed response of the liquid crystal itself. In recent years, the TFT for CDs, which has been rapidly popularized as "liquid crystal τν", has been used for the purpose of manufacturing stability and manufacturing cost. Amorphous 7TFT has advantages over other TFT technologies in the application of large-area glass substrates, so it has been used in LCDs for mobile phones, LCDs for notebook computers, displays for desktop PCs, and so on. TFT-LCD. One of the objects of the present invention is that, in the 3D display device, the application of the amorphous germanium TFT2LCD is naturally derived from the rationality that the medium to large LCD panel has been widely used. In addition, the use of an LCD with an existing amorphous TFT, even in the case of requiring TV applications such as enamel, is based on the premise of realizing a normal two-dimensional image, which lacks the extremely high-speed surface update required for 3D display. Inevitability, the premise of the present invention is to display a 1-inch surface in a time of less than 10 ms, and a high-speed writing of the TFT itself (the charging of the TFT) required for a clear distinction between the right-eye image and the left-eye image. It is also a state of near impossibility. Therefore, the high speed drive of the TFT is one of the important technologies of the present invention. Therefore, two major factors must be resolved. The above two major factors are necessary for the implementation of the concept of the invention. The TFT addressing time (the charging time of the TFT) is substantially shortened, and the other is the reduction of the electrostatic capacitance of the liquid crystal which can shorten the TFT addressing time of the TFT. The high-speed response of the liquid crystal itself corresponding to the high-speed writing of the TFT is also a necessary condition for implementing the present invention. Therefore, when the present invention is implemented, high-speed writing of a TFT and a high-speed response of a liquid crystal which are unprecedented in degree are necessary. The address time or screen update frequency of the TFT is determined by a number of parameters, but is exemplified by SXGA (Super Extended Graphic Array: 1280 x 1024 pixels). As is conventional, the TFT-LCD scans 1024 scan lines in a line-sequence with a frame frequency of 60 Hz (the so-called frame frequency is based on the frequency defined by a general TFT-LCD), and the scan time of each scan line. (equivalent to the charging time of the TFT) is 1 s / 60 / 1024 = 16.3 microseconds, which is almost the charging time of the amorphous germanium TFT known so far. Of course, the amount of static capacitance of the liquid crystal connected to each TFT also has an effect. In the present invention, the defined cut-off screen update frequency is 100 Hz, so the scan time (corresponding to the charging time of the TFT) of each of the above-mentioned pixels and the structure of the TFT is is/i〇〇/i〇 24 = 9.8 microseconds. In the combination of a general amorphous TFT and a conventional nematic liquid crystal, it is extremely difficult to charge a 9.8 microsecond TFT if the capacitance between the transistors, the wiring resistance, the parasitic capacitance, and the like are inconsistent and temperature dependent. There is an improvement in TFT or/and a reduction in the electrostatic capacitance of the liquid crystal. Even when the number of scan lines is increased, that is, when it is required to correspond to a higher-quality picture such as HD, it is inevitable that both the TFT side and the liquid crystal side are improved. In the actual TFT-LCD, the electrode portion to which each TFT is connected is provided with a liquid crystal as a static capacitance and a storage capacitor which can sufficiently maintain a higher electrode potential after the TFT is turned off. In this state, 201027124 is used as the equivalent circuit, as shown in Fig. 11. It can be easily understood from Fig. 11 that if the liquid crystal capacitor (Clc) and the storage capacitor (Cst) are increased, the load capacitance to the TFT will increase, and the charging time of the TFT must be prolonged. Therefore, the actual implementation and implementation of the present invention requires the high-speed charging of the TFT, the introduction of the high-speed response liquid crystal driving mode required for the implementation, and further, the liquid crystal necessary for the high-speed charging of the TFT by the above two-speed response to the liquid crystal driving mode. Reduced static capacitance and reduced storage capacitance.

Heretofore, it has been known that the optical response of the liquid crystal of the PSS-LCD is sufficient for implementing the south speed response of the present invention, but the charging of the TFT at a high speed is particularly necessary to reduce the electrostatic capacitance and storage capacitance of the liquid crystal, and the inventors have also explicitly stated It. For example, the electrostatic capacitance of the liquid crystal of Fig. 11 is more precisely, that is, the electrostatic valley C' of the pixel is a typical example of a conventional nematic liquid crystal, and the details thereof are as follows. (Example of calculation of static capacitance C of nematic liquid crystal) Average dielectric constant of liquid crystal: ε = 15 Dielectric coefficient of vacuum: eO = 8.854xl (T12F/m General electrode area of LCD for TV (RGB sub-pixel): S =300pmxl00pm Inter-pixel gap (panel gap): (1=3.50111 and £εΟ S/d, so C=1.14Pf=(Clc)--<l> and then 'storage capacitance (Cst) in general TFT design Then, it is Cst=1.0Clc to 2.0Clc...<2> Therefore, the capacitance of the actual TFT as a load is 2.28~3.42pF. Of course, the pixel capacitance calculated by the above calculation may also be used with the TFT-LCD. The design guidelines are different. The above is only the case where the TFT is amorphous 13 201027124. It is not limited to the above calculated values. In particular, tft is not amorphous, but low temperature polycrystalline 11 and high temperature. Polycrystalline (4), the mobility of electrons of tft will be much higher than that of amorphous chips, so even if the digits of the above calculated values are large, the charging of the transistor can be achieved. Conversely, the amorphous TFTs are constructed with pixels. Different uses may require the pixel capacitance to be reduced or decreased compared to the above. To the extent, as described above, the actual TFT There is also a so-called parasitic capacitance in the wiring room, etc. However, the purpose of this discussion is to fully discuss the above-mentioned capacitance, 2.28~3.42PF. The static capacitance applied to each TFT as a load is calculated as described above. 2.28 to 3.42 pF, but with respect to this value, if the gate length of the TFT is sufficient and the electron mobility of the transistor is insufficient, it is difficult to charge each TFT at the above-described high speed, such as each row line 1〇 In the case of the above-mentioned TFT, if the gate length of the TFT is sufficient, the TFT writing of each row line of 10 microseconds or less can be realized, but the above-mentioned high speed is performed with the capacitance of 3 pF for each pixel described above. When writing, the gate length must be designed to a sufficient length. If the gate length is increased, the light blocking portion of the LCD will increase, and as a result, there is a disadvantage that the aperture ratio is lowered and the brightness is remarkably lowered. High-speed line writing into the TFT-LCD requires that the electrostatic capacitance applied to the TFT be reduced to a conventional one-third, that is, 0.8pF to 1.lpF. In the PSS-LCD known so far, the typical pixel is Liquid crystal static For Clc=0.53pF ( ε =4 ' d=2pm), set the same storage capacitor (Cst) 'The static capacitance of each TFT will be l.〇6pF~1.59pF, and both exceed IpF, which will hinder Charging of TFTs 14 201027124 Therefore, in the present invention, in particular, the object of the present invention has been considered, and it has been conceived that no storage capacitor (Cst) is provided in the PSS-LCD. The usual TFT LCD2 storage capacitor (Cst) is necessary to maintain a certain potential of each pixel during the writing period of each frame. In the PSS-LCD, the necessity is the same. However, the present inventors focused on the result of driving the update of the frame of the speed of one of the important elements of the present invention, and found that the TFT is driven even without using the storage capacitor (Cst). In the high-speed driving necessary for the present invention, the influence of the decrease in the pixel luminance caused by the decrease in the pixel potential can be ignored. Therefore, in the case of the update of the frame speed, it has been found that in the pSS_LCD type, the pixel capacitance can be greatly reduced from 2 28 to 3 42 pF of the conventional TFT_LCD to Clc = 0.53 pF. According to the above invention, if an amorphous X-ray TFT is used, the speed-up TFT writing for the purpose of the present invention and the high-speed image update of ιοο or more can be realized. If the generalization of the above is made, the allowable pixel capacitance of each pixel of the TFT-LCD, which is an important component of the present invention, can be expressed as follows. (4) The area of each pixel of TFT-LCD: vertical and horizontal with claws (b) Panel gap of TFT-LCD: 2μηι (c) Dielectric coefficient of vacuum: e〇=8.854xl〇-uF/m (D) PSS liquid crystal Electric coefficient: ε : 4S ε $8 (e) Pixel capacitance of each TFT: c

C= ε ε 0 S/d=4.427ab ε xlO_18F In the above formula, the dielectric constant of the liquid crystal of PSS-LCD is in the range of 4 to 8 'Therefore, the pixel capacitance of each TFT is i7.708abxl〇-isF~35 416abx 10_18F. The pixel size of the pss-LCD screen of the general 40-degree degree: a, b points 15 201027124 is not 300μιηχ100μπι degree, so the pixel capacitance of each TFT pixel is 匸1 (:=0.53 mouth?~€=1. 〇6 port?, and is a very small pixel capacitance. Further, the following is an example of other procedures for implementing the present invention, but it is not limited to these methods. One is to configure a plurality of transistors for one pixel, and to drive at high speed ( Charging) the plurality of transistors, so at least the same number of data lines as the number of transistors arranged in one pixel must be arranged. By configuring a plurality of data lines, the TFTs can be shortened in proportion to the number of data lines. Charging time. The above type has been disclosed as a liquid crystal TV user for the existing two-dimensional image.

Ultra Definition LCD Using New Driving Scheme and Advanced Super PVA Technology : SID(Society for 〇

Information Display) 2008 Digest pp. 196-pp. 199, Paper number : 16.1· For high-speed charging of TFTs required to implement the present invention, it is necessary to further reduce the electrostatic capacitance of the liquid crystal as much as possible to reduce the connection of the source of the TFT. As the electrostatic capacitance of the load, and shorten the charge injection time of the TFT itself. Therefore, the so-called nematic liquid crystal type which has hitherto been marketed is difficult to achieve a trade-off between the response time of the liquid crystal and the electrostatic capacitance of the liquid crystal. That is, in order to shorten the response time, it is necessary to increase the driving torque of the liquid crystal. Therefore, it is generally necessary to use a liquid crystal material having a large electrostatic capacitance. However, if a liquid crystal having a large electrostatic capacitance is used, the load on the charge injection of 16 201027124 TF T will increase and the charging time will be prolonged, and as a result, the high-speed TFT charging required by the present invention cannot be achieved. In addition to shortening the charging time of the TFT itself, a smaller driving torque is required, so a smaller electrostatic capacitance must be introduced into a liquid crystal display mode capable of responding at a high speed (liquid crystal driving mode). One of the above requirements can be realized, that is, PSS- LCD type (for details of the PSS-LCD, refer to, for example, Japanese Patent Publication No. 2006-515935.) PSS-LCD can achieve extremely high speed response (300 microseconds) compared with the conventional nematic liquid crystal TFT-LCD. ), a very large angle of view, and a small static capacitance, so it contributes to the high-speed response of the TFT of one of the basic elements of the present invention, and the response of the liquid crystal itself is also high speed, so that other basic elements can also be satisfied. Method for measuring the capacitance of the pixel of the present invention There are several possible methods for measuring the electrostatic capacitance of the pixel of the present invention. The most general measurement method is as follows: A transparent electrode having a protective electrode of 20 mm is provided (the protective electrode is 20 mm in diameter) A glass substrate of 50 mm x 50 mm x 0.7 mm (thickness) of a concentric shape of 3 mm in size, and an empty panel is produced in accordance with the thickness (gap) of the liquid crystal to be measured. The method is the same as that of a general liquid crystal panel, and is prepared according to the liquid crystal driving mode. Here, a TN (twisted nematic) liquid crystal panel will be described as an example. The concentration of the solid portion of the commercially available polyimine for LCD is 2°. /〇, after coating by spin coating, drying on a hot plate, and then baking at 200 ° C for 1 hour. After falling to room temperature, the surface of the polyimide is ground in one direction. The rubbing direction and the rubbing direction of the other substrate paired with each other are 85 degrees. After the grinding, the plastic gap ball having an average particle diameter of 4.2 μm is spread on the substrate 17 201027124 by dry processing. The scattering density is an average of 1 square. 30 mm each. After spreading the gap ball, two pieces of glass are attached. The bonding is applied to the periphery of the square substrate by applying a thermosetting epoxy resin around the square substrate, and then temporarily hardened on the hot plate. Then, by means of lamination and hot pressing, the weight of each square centimeter is pressurized to a weight of 2 kg, and then the heat is solidified by the enthalpy of the entanglement. After being lowered to room temperature, it is injected into the market by the usual atmospheric pressure difference. Nematic mixture The composition is cleaned and the liquid crystal around the injection port is removed to form a sample. In this measurement, the sealing of the liquid crystal injection port is not required. The sample panel prepared above is used, and the load of the sample panel is measured using a CR bridge circuit. The CR bridge circuit is, for example, a commercially available precision LCR meter (manufactured by Agilent). The measurement of the sample panel is performed by using the detection frequency lKh and the peak-to-peak voltage lv, and the load of the sample panel is measured. The value is calculated using the electrode area and the gap of the sample panel (as the distance between the electrodes of the parallel plate capacitor), and the equation "1" and "2" of the calculation example of the electrostatic capacitance C of the nematic liquid crystal are used. Static capacitance c. The present invention encompasses such aspects as the representative aspects.

The present invention will be specifically described below by way of example. [Embodiment] Fig. 1 is a view showing a mode configuration of the present invention - an embodiment, in which a liquid crystal display device is shown. In the first picture, la backlight, lb system LCD panel, lc system data driver, ld system sweeping cat driver, u system optical shutter glasses, if optical fast eyeglass lens control circuit, lg liquid crystal display and optical shutter glasses synchronization Signal, lh is the optical shutter glasses control signal. The backlight la can be used for illuminating the liquid crystal panel 11 and using a cold cathode tube or a led light as a light source, and an optical film such as an expansion plate or a cymbal, a power source for a light source, or the like. 23 201027124 The liquid crystal panel 1b is composed of a glass substrate and a counter electrode substrate which are formed of the same TFT as the normal active matrix type, and a data driver (LSI) capable of driving the data electrode and a gate driver capable of driving the scan electrode ( ISI) is mounted on the TFT substrate directly or via a film substrate. The liquid crystal element constitutes the aforementioned PSS-LCD. The data driver lc and the scan driver Id are circuits for applying a predetermined voltage to each pixel of the liquid crystal panel 1b to display an image on the liquid crystal panel 1b according to the image data. The optical shutter glasses can transmit and block the image ® light from the liquid crystal panel lb, so that the left eye or the right eye can only view a specific image. Hereinafter, an example of the structure of an embodiment of an optical shutter will be described with reference to Fig. 2. In the figure, 2A of (A) is an incident side polarizing plate, 2b is a liquid crystal lattice, and 2c is a medium polarizing plate. The arrows attached to the incident side polarizing plate 2a and the intermediate polarizing plate 2c respectively represent the transmission axes of the polarizing plates. The transmission axis of the incident side polarizing plate 2a is adjusted to coincide with the direction of the polarization axis of the polarized light of the outgoing image light of the liquid crystal panel 1b of Fig. 1. (B) is a structure in which two liquid crystal lattices are used in order to reduce the amount of light leaked at the time of blocking and to increase the contrast ratio between the transmission and the blocking of light. 2a is an incident side offset 振 vibration plate ' 2b and 2d is a liquid crystal lattice, 2c is a middle polarizing plate, and 2e is an outgoing side polarizing plate. The arrows attached to the incident side polarizing plate 2a, the intermediate polarizing plate 2c, and the exit side polarizing plate 2e represent the transmission axes of the individual polarizing plates. The transmission axis of the incident side polarizing plate 2a is adjusted to coincide with the polarization axis direction of the outgoing polarized light of the liquid crystal panel 1b of Fig. 1. Hereinafter, the operation of the optical shutter glasses will be described with reference to Figs. 3 and 4 . Fig. 3 is a description of the operation of Fig. 2(A). In the figure, the same as the one shown in Fig. 2, Fig. 24, 201027124, which is denoted by the same reference numeral, 3a is used to drive the AC power supply of the liquid crystal cell 2b, and the 3b system is used. The polarization axis direction '3c of the outgoing polarized light of the liquid crystal panel 1b of Fig. 1 is the polarization direction of the polarized light which is emitted through the liquid crystal cell 2b, and 3d is the polarization direction of the polarized light which is emitted by the intermediate polarizing plate 2c. In the figure, (a) shows the state of the photoresist. First, the direction of the polarization axis of the outgoing polarized light of the liquid crystal panel 1b of Fig. 1 coincides with the transmission axis of the incident side polarizing plate 2a, so that the image light from the liquid crystal panel is transmitted. Next, a high voltage is applied to the liquid crystal cell 2b so that the arrangement of the liquid crystal molecules in the liquid crystal lattice is optically isotropic. Therefore, even if the liquid crystal lattice is transmitted, the polarization state is not changed, and the liquid crystal lattice emits polarized light 3c. Then, the polarization direction of the outgoing polarized light of the incident side polarizing plate 2a (the transmission axis direction of the incident side polarizing plate) is the same. Finally, the transmission axis of the exit-side polarizing plate 2c is set to be perpendicular to the polarization direction 3c of the liquid crystal lattice outgoing polarized light, so that the polarized light incident on the exit-side polarizing plate 2c is absorbed by the exit-side polarizing plate and blocked. (B) is a description of the light transmission state. The image light is transmitted through the incident side polarizing plate 2a and is incident on the liquid crystal cell 2b, and is the same as (A). A low voltage is applied to the liquid crystal cell 2b, and is set to have an optical λ/2 wave plate function. Therefore, the polarized light transmitted through the liquid crystal lattice will rotate the polarization direction of the polarized light by 90° due to the liquid crystal lattice. For example, the liquid crystal lattice exits the polarized light polarization axis direction 3c. The transmission axis of the exit-side polarizing plate 2c coincides with the direction in which the liquid crystal lattice exits the polarization axis direction 3c of the polarized light, so that it can be emitted as the image light 3d and viewed by the naked eye. Fig. 4 is a description of the operation of Fig. 2(B). In the figure, the same reference numerals '4a and 4b' are used to drive the AC power supplies of the liquid crystal cells 2b and 2d, respectively, as shown in Fig. 2. 4c is the polarization axis direction of the outgoing polarized light 25 201027124 of the liquid crystal panel 1b of FIG. 1 , 4 (and the polarization direction of the polarized light which is emitted through the liquid crystal lattice hole and 2{1 respectively), 4f is the exit side The polarization direction of the polarized light emitted from the polarizing plate 2e. In the figure, (A) illustrates the state of the photoresist. First, the polarization axis direction of the outgoing polarized light of the liquid crystal panel ib of Fig. 1 and the transmission of the incident side polarizing plate 2a. Since the axes are the same, the image light from the liquid crystal panel will be transmitted. The person applies a high voltage to the liquid crystal cell 2b, so as described above, even if the liquid crystal lattice is transmitted, the polarization state is not changed, and the liquid crystal lattice is emitted. The polarized light 4d is the same as the polarization direction of the outgoing polarized light of the incident side polarizing plate 2a (the transmission axis direction of the incident side polarizing plate). Second, the transmission axis of the intermediate polarizing plate 2c © is set to the polarization direction of the polarized light emitted from the liquid crystal lattice. Like the direction of the vertical, so The polarized light incident on the middle polarizing plate will be absorbed by the middle polarizing plate and blocked. However, the absorption of the polarizing plate is not 1%, and will be leaked and transmitted by about several %. The slightly leaked and transmitted polarized light is followed by Since a high voltage is applied to the liquid crystal cell 2d, even if the liquid crystal lattice is transmitted, the polarization direction of the polarized light is not changed, and the liquid crystal lattice is emitted in the direction of 4e. Here, the transmission axis of the exit-side polarizing plate 2e is finally transmitted. The polarized light incident on the exit-side polarizing plate is absorbed by the exit-side polarizing plate and blocked by the direction perpendicular to the polarization direction 4e of the polarized light emitted from the liquid crystal cell 2d. The structure of the second (B) is blocked. The absorption process of the polarizing plate including the transmission axis perpendicular to the polarization axis of the incident polarized light is performed twice, so that the amount of light that is not absorbed by the polarizing plate and leaks is reduced to two compared with the structure of the second (A) figure. (B) indicates the light transmission state. The image light is transmitted through the incident side polarizing plate 2& and before entering the liquid crystal cell 2b, it is the same as (A). The liquid crystal lattice 2b is applied 26 201027124

As described above, the polarized light transmitted through the liquid crystal lattice will rotate the polarization direction of the polarized light by 9 因 due to the liquid crystal lattice. And, as the liquid crystal lattice is out - the direction of polarization of the polarized light is 4d. The transmission axis of the intermediate polarizing plate 2c coincides with the direction in which the liquid crystal lattice exits the polarization axis direction 3c, so that the image light is transmitted. Next, a low voltage is applied to the liquid crystal cell 2d. As described above, the polarized light transmitted through the liquid crystal lattice rotates the polarization direction of the polarized light by 90 due to the liquid crystal lattice. However, as the liquid crystal lattice exits the polarized light, the polarization axis direction is φ. Finally, the transmission axis of the exit-side polarizing plate coincides with the direction of the polarization axis direction 4e of the liquid crystal lattice exiting polarized light, so that it will be emitted as if it were imaged and can be viewed by the naked eye. (The timing of switching between image update and optical shutter glasses) - The image update of the crystal panel and the transmission, resistance, and absolute switching timing of the optical glasses. The fifth and eighth diagrams illustrate the state of one embodiment (eight). In the figure, the symbol 5a in Fig. 5 represents the direction in which the liquid crystal panel image data is updated. In the figure, (4) shows the time on the horizontal axis, and G% shows the image written on the LCD panel, the relationship between the image and the time when the image is updated, and the switching timing of the optical shutter glasses. Here, Fig. 5B is a view for explaining the case where the SXGA (1280 x 12 像素 24 pixels) image is driven by the screen update period of 8 times. In Fig. 5B, two scans of the same-image data are performed during the screen update period. During the update of the scan for the left eye image 1, the previous frame will update the image for the right eye in sequence, so that the display image of the liquid crystal panel before the end of the broom period presents the state of coexistence between the right eye and the left eye. , the right eye, the left eye are not 27 201027124 law to watch. During the above-mentioned broom, the broom time of the screen is maintained at a certain driving time of the screen, which is 1/2 of the time of the screen update period. However, the above description is only an example, and the scanning period of the left-eye image i and the scanning process of the right-eye image 2 need not be the same. If you view an image that coexists with the image for the right eye and the image for the left eye, crosstalk will occur and the 3D image quality will be significantly reduced. Therefore, both the left-eye optical shutter and the right-eye optical shutter are in a state of absolute state. After the scanning of the left-eye image 1 is completed, the right-eye t/image 2 (the same image as the left-eye image i) is displayed in the scanning period, and only the left-eye image is displayed on the liquid crystal panel, so only The left eye optical shutter is made transparent. However, after the image data for the left eye has been electrically input, the liquid crystal will not respond and the optical change will be slower, so the response time of the response of the PSS-LCD in the interval of 1 〇〇μ8 to lms (the first touch map). During the update scan of the right eye image 1, the previous image has been written to the left eye image. Therefore, before the end of the scanning interval, the display image of the liquid crystal panel is in a state in which the right eye and the left eye coexist. As described above, the right eye and the left eye cannot be viewed. Therefore, both the left-eye optical shutter and the right-eye optical shutter © are blocked. After the scanning period of the left-eye image 1 is completed, in the scanning period of the right-eye image 2 (the same image as the right-eye image), the liquid crystal panel displays only the right-eye image, so only the right-eye optical is made. The shutter is in a light transmitting state. Here too, the response waiting time is set. If the control is performed according to the present embodiment, the right eye can only view the right eye image, and the left eye can only view the left eye image, so that the 3D display can be realized. Fig. 6 is a diagram showing other embodiments (B) and aspects [9]. In the left eye shadow 28 201027124 image and right eye (4) update _ period, the distribution line broom. During the update scan of the left-eye image, the previous frame has been written with a black image, so the right (four) image will not be stored in the above-mentioned sweeping room. In addition, in the left eye image update scan _ between the money, although the black image update scan = but the current period of money does not coexist with the right eye image. Therefore, the above-mentioned left eye use = update scan _ and the black image of money turn more _ between, the left eye is light-transparent, and the right-eye optical shutter is blocked. Right eye 〇 上: During the update of the broom, the previous frame has been written with a black image. Therefore, during the 晦 period, the left eye image will not be saved. χ, the image for the right eye, after the end of the cat period, although the black image update broom, but the left eye image is not coexisted during this period. Therefore, the above-mentioned image for the right eye is updated during the scanning of the cat and the black image of the towel, and the right eye is fast (4) through the green state, and the Wei optical fast is in a state of resistance. Here, the time to write the black image is also set to wait for the time (Fig. 66). If the control is performed according to the embodiment, the right eye only views the right (four) image, and the left eye only views the left eye image, so that it can be displayed 3 times. And the right figure illustrates other embodiments (C) and aspects [ίο]. Left-eye image 1 time limit image update scan period is set to be shorter than the update period for each update scan period in the individual image update period. During the period of the image for the left eye, the 'previous frame has been written to the image for the right eye. Therefore, the display image of the liquid crystal panel before the end of the field is displayed in the state where the right eye and the left eye coexist, so as described above. Eyes and left eyes are unable to view. Both the left-eye optical shutter and the right-eye optical shutter are blocked. 29 201027124 After the scanning period for the left-eye image ends, the right-eye image scanning period starts, the LCD panel displays only the left-eye image, so only the left-eye optical shutter is transparent. During the update scan of the right-eye image, the previous frame has been written to the left-eye image. Therefore, before the end of the scanning period, the display image of the liquid crystal panel is in a state in which the right eye and the left eye coexist. The left-eye optical shutter and the right-eye optical shutter are all blocked. Right eye After the scan period of the image is finished, the liquid crystal panel displays only the image for the right eye before the start of the image scan period for the left eye, so only the right eye optical shutter is in a light transmitting state. Here, after the left (or right) image is written, a response, etc., is set in the middle (p. 7B). If the control is performed according to the embodiment, the right eye can only view the right eye image, and the left eye can only view the left eye image, so that the 3D display can be realized. Figure 8 is a view showing an embodiment (D) and aspect [12] of the present invention. During the update scan of the image AU), the previous frame has been written to the image B. Therefore, before the end of the scanning period, the display image of the liquid crystal panel shows the state in which the image A and the image B coexist, so the glasses for the image A are worn. The audience and the viewers wearing the glasses b can not watch. Therefore, the glasses for the image A and the glasses for the image b are blocked. After the scanning period of image A (l) is finished, the image A (2) (the same image as the image A (l)) is scanned during the scanning period. 'The liquid crystal panel only displays the image A, so only the image A is transparent with the glasses. Light state. During the update of the image B(l), the previous frame has been written with the image A'. Therefore, before the end of the scanning period, the display image of the liquid crystal panel shows the state in which the image A and the image B coexist, so the image a is worn. Viewers who use glasses and viewers who wear glasses for image B are not able to watch. 30 201027124 Therefore, 'image A glasses and image glasses are blocked. After the end of the sweeping period, the image B (7) (the same period as the image is _ 'the liquid day and day panel only displays the image B, so only the image b is in the light transmission state. If the embodiment is switched, the control is performed. Can be equipped with ^

Like A, the audience with glasses can watch the image, while wearing the image Qiu I can view the image B. Fig. 9 is a view showing another embodiment (6) and aspects. In image A and

After image B updates the broom, the black image update broom will be performed separately. The image A's update scan _ between the 'previously' has written a black image, so the image B will not coexist during the above-mentioned sweeping period. Further, after the image A is updated, the black image update_ is performed, but the image B is not coexisted in the _. Therefore, during the update of the black image during and after the scan of the image A, the image A is in a light-transmissive state, and the image B is in a blocked state. During the image B update scan, the previous frame has been written to the black image. During the above-mentioned sweeping period, the image A will not coexist. In addition, after the image B is updated, the broom period = the end of the process, the black image is updated to sweep the cat, but during the period, the image is not stored in the same period, and the image B is updated during the sweeping period. 'Image B glasses are in a light-transmissive state, and image A glasses are blocked. If (4) is carried out according to the embodiment of the present embodiment, the viewer who wears the image A with the glasses can view the image A, and the viewer who wears the image b can view the image B with the viewer of the glasses. The first drawing illustrates another embodiment (F) and the aspect [14]. The image a and the image B are updated during the scanning of the cats in the individual images (four) periods, and the period during the update of the cats is set shorter than the update period. During the update of the image A, during the scanning of the cat 31, the previous image of the image has been written to the image B. Therefore, before the end of the broom period, the display image of the liquid crystal panel shows the state in which the image A and the image B coexist, so the glasses for the image A are worn. The audience and the audience wearing the image B secret mirror are unable to watch. Therefore, both the image A glasses and the image B lens are blocked. After the brooming period of the image A is finished, the liquid crystal panel displays only the image A before the start of the image B scanning period, so only the image A is in a light transmitting state with the glasses. During the update of the image B, the previous frame has been written with the image a. Therefore, before the end of the scanning I* field period, the display image of the liquid crystal panel shows the state in which the image A and the image B coexist, so that the image is worn. The audience, the audience wearing the image b and the eyeglasses are unable to watch. Therefore, both the image A glasses and the image B glasses are in a blocked state. After the brooming period of the image B is completed, before the start of the image A scanning period, the liquid crystal panel displays only the image B, so only the image b is in a light transmitting state with the glasses. If the control is performed according to the embodiment, the viewer who wears the image-A glasses can view the image a, and the viewer who wears the image B can view the image B. First Comparative Example A model test was conducted on an amorphous germanium TFT line drive having a pixel size of 300 μηι χ 100 μΓη and a pixel electrostatic capacitance of 8 pF. The analog gate length is 4 μm, and the result of the time before the TFT is charged from 0 V to 5 V is 99.8% with respect to 5, that is, the time to charge to 4.99 V is 30.8 μsec. In other words, when the pixel is driven by the TFT, the number of lines of one line of the object of the present invention is driven by a frame rate of 1 〇〇ΗΖ or more, and the charging time for each line is 1/1000>; 1/100=10 (microseconds) or less, the required charging time is shorter than 30.8 microseconds, and it is determined that sufficient charging cannot be achieved. 32 201027124 The second comparative example uses a so-called liquid crystal TV driven by a commercially available 120 Hz frame rate, and divides the frame into 60 Hz and 60 Hz, and forms a right-eye image in the front 60 Hz (16.7 ms), and at the rear. A 3-dimensional image was confirmed by forming a left-eye image 'and synchronizing with the switching of the liquid crystal optical shutter glasses of the first application of the present invention in 6 Hz (16.7 ms). As a result, the switching between the left and right images is not sufficient, and the crosstalk of the so-called left and right images is apparent.
