The display unit area 140 may be a display panel for displaying an image, and includes a pixel matrix composed of a plurality of pixels. In the embodiment, when the display unit area 14 is a liquid crystal display (LCD), It is necessary to provide the first polarizer 130 and the second polarizer 132 on the light incident side and the light exit side of the display unit area 140, respectively. In another embodiment, when the display unit area 140 is an organic light emitting diode (OLED), it is only necessary to provide the second polarizer 132 on the light emitting side of the display unit area 140. The light generated by the backlight module 1〇2 is irradiated to the first polarizer 130. The first polarizer 130 has a transmission axis and an absorption axis perpendicular to the transmission axis. When the unpolarized light generated by the backlight module 102 is incident, the light of the polarization axis substantially parallel to the transmission axis of the unpolarized light 201122552 is transmitted, and Light that has a polarization axis that is substantially parallel to the absorption axis is blocked. The first polarizer 130 has about 1% based on the observer side. The transmission axis is set so that the transmission has a view of about 135 seen by the observer. The function of the light of the polarization axis ❶ is as follows. The angle of the polarization axis indicates the angle viewed by the observer side unless otherwise specified. The second polarizer 132 has a height of about 45 on the observer side. The transmission axis is set so that the transmission has a viewing angle of about 45 as viewed by the observer. The function of the light of the polarized axis. The synchronizer 1〇4 is coupled to the backlight module 102, the display unit area 14〇, and the twisted nematic unit layer 163 for synchronously controlling the operation of the display unit area 14〇 and the shutter 160. The pixel of the display unit area 140 displays the image for the right eye when receiving the second data voltage signal R, and displays the image for the left eye when the first data voltage signal L is received. When the right-eye image light or the left-eye image light is incident on the polarizer 132, the light whose two axes of polarization are parallel to the transmission axis of the polarizer 132 will penetrate the polarized light>{132, but parallel to the absorption axis of the polarizer m. The light will be blocked. The twisted nematic unit layer 163 is sandwiched between the two layers of conductive glass layers 166. The conductive glass layer 166 疋 ITO conductive layer, when the conductive glass layer 166 receives a switching signal, the TN liquid crystal molecules in the unit layer is rotated according to the voltage difference of the applied switching signal, and the polarizing film 132 is emitted. After the incoming light passes through the TN unit layer 163, its polarization direction maintains the illusion. Since the angle between the absorption axis of the quarter-wavelength plate 170 and the polarizer 132 is 45 degrees, it becomes a right-handed circularly polarized light after a quarter of the wavelength plate no. If the conductive glass layer 166 does not receive the switching signal, the light incident from the polarizer 132 passes through the tn unit layer 163, and the polarization direction thereof becomes 135 degrees, and then passes through the quarter-wavelength sheet 17 and becomes Left-handed circularly polarized light. Using the above principle, the synchronizer 104 functions to form a right-handed rotation when the display unit area 14 emits the right-eye image light as long as the scale output is turned off to the conductive glass layer 1 so that the right-image light 201122552 passes through the TN unit layer 163. Circularly polarized light; when the display unit area 140 emits image light for the left eye, the 'synchronizer 104 does not output a switching signal to the conductive glass layer 166 so that the left-eye image light passes through the unit cell layer 163 to form left-handed circularly polarized light. The circular lens 200 corresponds to a polarizer having different polarization directions on both sides of the observer's left and right eyes. Therefore, only the right circularly polarized light can be seen through the polarizer on the right lens, and the polarizer on the left lens can only be seen. To the left-handed circularly polarized light. Once the observer wears the circular eccentric glasses 200, as long as the moderate control is the synchronization state of the ΤΝ unit layer 163 and the display unit area 140, the eyes can be divided into different images, so the human brain can perceive that it is seen. 3D image. Referring to Fig. 3, Fig. 3 is a schematic view showing the display unit area 14A and the unit unit layer 163 of the first embodiment of the present invention. The display unit area 14 is scanned in the direction indicated by the arrow 采 in a column by column until the last column is scanned, which is called a picture update frequency. Then continue to scan in the first column. In order to prevent the single eye from feeling a flickering situation, in the present embodiment, the face update frequency of the display unit area 14A is recommended to be 24 inches. The pixel of the display unit area 140 displays the right-eye image when receiving the second data voltage signal R, and displays the left-eye image when receiving the first data voltage signal L. In the nth picture, initially, the pixels of the display unit area 140 display the right-eye image when receiving the second data voltage signal R. At this time, the single layer 163 does not receive the switching signal and is turned off, so the right eye image light Right-handed circularly polarized light is formed through and through the quarter-wavelength plate 170. Therefore, the right eye image is seen through the right eye of the observer through the right eyeglass lens of the polarized glasses. At the N+1th screen, the entire display unit area 14 receives a black signal, so the picture is completely black. In the N+2 picture, the pixels in the display unit area 14〇 display the left-eye image when receiving the first data signal L. At this time, the other unit layer (6) receives the switching signal and turns on, so the left eye image light can be The left-handed circularly polarized light is formed through and through the quarter-wavelength Μ 201122552. Therefore, through the left eye lens of the circular lens 200, the left eye of the observer can see the image for the left eye. Finally, in the N+3 face, the entire display unit area 14〇 receives a black signal “so the black face is completely black. The display unit (10) is interspersed between the display left image and the right eye image. The black signal, so there will be no occurrence of the first-long voltage signal l and the second material voltage 峨R simultaneously entering the display list · 14G. Moreover, the left-eye image and the right-eye image are separated by 6 New Zealand, so there is no problem of painting. Please refer to FIG. 4'. FIG. 4 is a schematic view showing the display unit area (10) of the second embodiment of the present invention, the single-turn layer I63 and the backlight module 1〇2 being actuated. In order to prevent the single eye from feeling the flicker φ, it is suggested that the fresher unit cell 14G_ face is more than 120 Hz. The ride of the display unit area M0 receives the second long-ray signal R_showing the right_image, and displays the left-eye image when receiving the first-data voltage signal L. In the Nth picture, the damaged pixel of the display unit area 140 displays the right eye image when receiving the second data voltage signal R, and some pixels display the left eye image when receiving the first data voltage signal L. The unit layer 163 does not receive the switching signal and turns off. However, the backlight module (10) is turned off and does not provide light. Therefore, the observer cannot see the image for the right eye and the image for the left eye, so there is no vision. Question # on the question. Until all pixels of the entire display private area 14G receive the second mixed voltage signal r, that is, the N+1th gold surface, the backlight module 1〇2 will turn on to provide light, and the grab unit layer 163 does not receive the off signal. And off' so the right eye image light can pass through and form a right-handed polarized light via the quarter-wavelength plate 170. Therefore, the right eye image can be seen through the right eye of the right eyeglass viewer of the rounded pair of glasses. Next, the entire display unit area 14〇 is updated to display the left-eye image. Therefore, when the N+2 is in the N-th surface, some pixels display the right-different when receiving the second data voltage signal r, and some pixels are connected. (4) - Wei voltage signal [time_left eye shadow 12 201122552 image 'but at this time the backlight module 102 is off and does not provide light, so the observer can not see the left eye image and can not see the right eye image, So there will be no visual problems. Until all the pixels of the entire display unit area 140 receive the first data voltage signal ,, that is, the N+3 昼 plane, the driving module 102 turns on to provide light, and the χΝ unit layer 163 receives the switching signal and turns on. Therefore, the left-eye image light passes through and forms a left-handed circularly polarized light via the quarter-wavelength plate 1?. Therefore, the left eye image is seen by the left eye of the observer through the left eye lens of the rounded pair of glasses. Since the backlight module 102 is turned off between the display left-eye image and the right-eye image in the display unit area 14 without providing light, the observer does not see the first data voltage signal and the first data at the same time. When the voltage signal R is simultaneously input to the display unit area 14〇, and the interval between the left-eye image and the right-eye image is 6QHz, the problem of flickering of the screen does not occur. Referring to FIG. 5, FIG. 5 is a schematic diagram of the display unit area 14A, the other unit layer 163, and the backlight module 1〇2 of the third embodiment of the present invention. The display unit area i4 is scanned in the direction indicated by the arrow B in a row-column manner until scanning to the last __ column, which is referred to as a face-to-face update frequency. Then continue to scan in the first column. In order to prevent a single eye from feeling awkward, the embodiment in which the picture update frequency of the display unit area 14G of the present embodiment is 120 HZ or less will be described with a face update frequency of 120 Hz. Actually, the picture update frequency is not The optical module 1G2 includes a first optical component (10) and a second light source group 120 ′. Preferably, the first light source group 11 〇 and the second light source group 12 占 respectively occupy the light emitting area of the backlight module ι 2 The half "display unit area 14" includes - the first display area (4), and the second display area recognizes the first display area 143. The pixel of the display unit area 14〇 displays the right eye image when receiving the second data voltage signal R and the left eye image when receiving the first material touch field L. Please - see also 6@, Figure 6 is a flow chart of the method of the present invention. As shown in step 6〇2, 13 201122552 firstly 'when scanning to the second display area 142', the first display area 141 and the second display area 142 receive the first-bee voltage signal L' and the third display area 143 The second bedding voltage sfl number R' received by the front-surface is maintained, and the TN cell layer 163 is turned on, and the first light source group 110 receives the first-start signal to generate the first light. Therefore, the first display area (4) and the second display area 142 display the image according to the first wire, because the second light source group 12 () is closed, the third display area 143 receives the second data voltage signal R, but the light is Insufficient, so the human eye cannot see the image displayed in the second display area 143. Next, as in step 6〇4. When the first display area (4) receives the second data voltage signal R, the second display area M2 and the third display area 143 receive the first data voltage signal l (10) the unit layer 163 receives the switching signal 'and the second light source group 12 touches The second start signal generates a second light. The second display area 142 and the third display area 143 display an image according to the second light. Simultaneously,

Please note that the _ signal, the second start 峨 and the first start The frequency of the signal is equal to the scan-half of the display device. In the embodiment, the display device has a feeding frequency of 120 Hz′ and the frequency of the switching signal is 60 Hz, the second activation signal and the first activation signal. The frequency of the county is 12 Hz. The synchronizer 1G4 can be used to accurately output the off signal, the second start signal and the first start signal. Thus, when the viewer views the image displayed by the display unit area 14 Not only will the resolution not decrease, There is also no display problem of different data signal voltages on the same display unit layer 14 . Please refer to FIGS. 7A and 7B , and FIGS. 7A and 7B are diagrams showing the display unit area 140 of the fourth embodiment of the present invention. The TN unit layer 163 and the backlight module 1〇2 are schematic diagrams when the operation is performed. The display unit area 140 is scanned in the direction indicated by the arrow B until the last column is scanned, and this period is called The frequency is updated for a picture. Next, the first column continues to select the picture. In order to prevent the single eye from feeling the flicker, the face update frequency of the display unit area 14〇 is recommended to be 120 Hz. The following embodiment will be The update frequency is 12 Hz for the description. Actually, the face update frequency is not the ship. The backlight 102 includes the first group UG, the second light source group 120, the second light source group 112, and the fourth light source group 122'. Preferably, the first light source group 110, the second light source group 120, the third light source group 112, and the fourth light source group 122 respectively occupy one quarter of the light emitting area of the backlight module 1〇2. The display unit area 140 includes a first a display area ι41, a second display area m2, 15 201122552 The three display areas 143 and a fourth gs-r, the display area 144. Preferably, the display areas (4), 142, 143, 144 occupy an area of four _ of the display unit area 14 。. The display unit area 〇 The pixel displays the right image when receiving the second data voltage, and the left eye image is displayed when the first data signal L is transmitted. As shown in Fig. 7A, first, |^ a scan to the third display area At 143, the first display area (4), the second display area 142, and a portion of the scanned flute-first display area 3 receive the first data voltage signal L, and a portion of the third display area 丄43 that has not been scanned yet The fourth display area 144 maintains the second data voltage signal R received by the previous side. The object unit layer 163 receives the switching signal and turns on, and the first light source group U0 connects (4) to the start signal to generate light. Therefore, the first display area (4) displays an image in accordance with the light of the first light source group 11G. At the same time, since the light source groups m, 12G, and 122 are turned off, the partial (four) three display 143 and the fourth display area 144 receive the second data voltage signal R, but the second display area 142 cannot be seen by the human eye due to insufficient light. The images displayed by the third display area 143 and the fourth display area 144. Next, the broom is continued. When scanning to the fourth display area M4, the first display area (4), the second display area 142, the third display area 143, and the partially scanned fourth display area 144 receive the first data. The second light source voltage signal R R is received by the second light source group 120, and the second light source group 120 receives the second start signal. And produce light. Therefore, the second display area 142 displays an image according to the light of the second light source group 120. At the same time, since the light source groups 112, 12A, 122 are turned off, the first display area 141, the third display area 143, and the fourth display area 144 are not visible to the human eye, so the human eye cannot see the first display area 141 and the third display area. The images displayed by 143 and fourth display area 144. 201122552, when the second display area 142, the third display area I43, the fourth display area 144, and the partially scanned first display area 141 receive the first data voltage signal L, The second data source signal R is received by the first display area 141. The TN unit layer 163 receives the switching signal and turns on, and the third light source group 112 receives the third activation signal to generate light. Therefore, the third display area 143 displays an image according to the light of the third light source group 120. At the same time, since the light source groups 110, 112, and 122 are turned off, the first display area 141, the second display area 142, and the fourth display area 144 cannot see the displayed image by the human eye due to insufficient light. When scanning to the second display area 142, the first display area 142 and the partially scanned second display area 142 receive the second data voltage signal R, and the second display area M2 and the third portion that are still not scanned. The display area 143 and the fourth display area 144 receive the first data voltage signal [wherein the TN unit layer 163 receives the switching signal and turns on, and the fourth light source group 122 receives the fourth activation signal to generate light. Therefore, the fourth display area 144 displays an image according to the light of the fourth light source group 122. At the same time, since the light source groups 110, 112, and 120 are turned off, the first display area 141, the second display area 142, and the third display area 143 cannot see the displayed image because the light is insufficient. As shown in Figure 7B. When scanning to the third display area 143, the first display area (4), the second display area 142, and the third display area 143 of the portion (four) receive the first thermal voltage signal l, and the third display portion has not been scanned. The area 143 and the second display area 144 maintain the second data voltage signal R received by the front picture, and the W unit layer 163 does not receive the switching signal and is turned off, and the first light source group no receives the first start signal to generate light. . The first display area (4) displays an image according to the light of the first-light source group U0. At the same time, because the light source groups 112, 12G, 122 are closed, some of the third display area 143 and the first display area 144 receive the second data electric ship, and the mosquitoes are insufficiently lighted, so the human eye cannot see the second display area. 142. The image β displayed by the third display area 143 17 201122552 and the fourth display area 144 continues to scan downward. When scanning to the fourth display area 144, the first display area 141 and the second display area 142, The third display area 143 and the partially scanned fourth display area 144 receive the first data voltage signal L' and the fourth display area 144 that has not been scanned remains the second data voltage signal R received by the previous writing. At this time, the W unit layer 163 does not receive the switching signal and is turned off, and the second light source group 120 receives the second activation signal to generate light. Therefore, the second display area 142 displays an image according to the light of the second light source group 120. At the same time, since the light source groups 112, 12A, 122 are turned off, the first display area 141, the third display area 143, and the fourth display area 144 cannot see the first display area 141 and the third because the light is not light enough. The images displayed by the display area 143 and the fourth display area 144. When the second display area 141, the second display area 142, the third display area 143, and the fourth display area 144 are scanned, the first data voltage signal L is received. The first display area 141, which is still not scanned, receives the second data voltage signal R', and the TN unit layer I63 does not receive the switching signal, and the third light source group 112 receives the third activation signal to generate light. Therefore, the third display area (4) displays an image according to the light and line parameters of the third light source group (9). At the same time, since the light source groups 11A, 112, and 122 are turned off, the first display area M1, the second display area 142, and the fourth display area 144 cannot be seen by the human eye because of insufficient light. When scanning to the second display area 142, the first display area 142 and the partially scanned second display area 142 receive the second data voltage signal r, and the first unscanned first display area ι41, the third The display area 143 and the fourth display area 144 receive the first data voltage signal L, and the first display area 141 receives the second data voltage signal R. At this time, the coffee unit layer 163 does not receive the switching signal and the 18 201122552 is turned off and the fourth The light source group 122 receives the fourth start signal to generate light. Therefore, the fourth display area I44 displays an image according to the light of the fourth light source group 122. At the same time, since the light source groups 11A, 112, 120 are turned off, the first display area 14 and the second display area 142 and the third display area 143 cannot be seen by the human eye because of insufficient light. Please note that the frequency of the switching signal is equal to half the scanning frequency of the display device. Taking the embodiment as an example, the scanning frequency of the display device is 12 Hz, and the frequency of the switching signal is 60 Hz, but the frequency of each light source group is 12 〇H2^ in this order. When viewing the image displayed by the display unit area 140, not only the resolution is not reduced, but also the display problem that different data signal voltages are seen by the user on the same display unit layer 140. The main advantage of the display unit area 14〇 and the backlight module 102 being divided into four areas is that the brightness distribution of the backlight module 102 at the boundary of each two light source groups is not very bright and dark, but continuous, so the backlight When the bright area of the module 102 is very close to the display area being scanned, it is easy to cause crosstalk. Therefore, after the backlight module 1〇2 is divided into four regions, the distance between the bright region of the backlight module 102 and the display region being scanned can be increased to reduce the interference. The display device of the present invention may be a display device capable of simultaneously displaying different images. For example, a stereoscopic image display device which can be used for the parallax of the money eye can display the display device which can observe different images by the left and right observers. More specifically, it can be used for a liquid crystal television, a liquid crystal display, a plasma display, a projector, a medical display device, or the like.
