For example, the image of the original image is 128*160. The left eye will see the group of 64x160 elements, and the right. The eye will see another set of 64 χ 16 〇昼 patterns; when the display frequency is in the time domain of even frequency, the grating 1 (·) is turned off (transparent) and the illuminating 2 (TN2) is activated (shading) 'the left eye at this time Only the sub-salm on the right side of each notch of the grating 2 (TN) can be seen, while the right eye can only see the sub-alliment on the left side of each notch of the grating 2 (ΤΝ2), grating • 2 ( 2) The arrangement of the sub-forms seen in the left and right eyes is the state shown in Figure 2, taking a picture with an original image of 128*160 pixels as an example, and the left eye will see a set of 64x160 pixels. The right eye will see another set of 64χ16〇昼 patterns. Since the grating 1 (ΤΝ1) and the grating 2 (ΤΝ2) are complementary and staggered, the left and right eyes are respectively seen at the even frequency, just like The left and right eyes are adjacent to the odd-numbered frequencies of %%. In other words, in one display period, the left and right eyes will respectively see two different sets of adjacent 64-inch 16-cell graphics. Under the effect of the visual temporary edge, the human eye's visual experience is equivalent to seeing a set of morphological figures. Moreover, since the left and right eye systems respectively see different independent images, they will present 128 under naked eye vision. *160 昼 3D image. As can be seen from Fig. 3, in different grating 1 (Τ1) and grating 2 (Τ2) time, the fixed sub-pixel will change to the left eye or the switching time of the grating 1 and the grating 2 It is the display material for viewing by the right eye. Figure 4 is a conventional 3D stereo display. It can be seen that the grating 1 (Τ1) and the grating 2 (τ2). The opening and closing time is kept at 8.3ms, and the odd-numbered box (in this Field) and the even-numbered box (Even 200812368 • ) are not scanned in the gate. Finished, so during the odd and even frame scans, there is a _ need to turn off the backlight, and then wait for the LCD steady state (ITD fematlon) time, this part is after scanning the last sweep line (with line) Waiting for the time required for the liquid crystal to complete, after completion, the backlight is activated, and the human eye can receive the correct 3D image. However, this driving method will cause the brightness of the overall 3D display to decrease. SUMMARY OF THE INVENTION The problem of a decrease in the luminance of the overall 3D display is caused by the conventional driving method. The main object of the present invention is to provide a driving method for enhancing the 3D stereo head shell degree without loss of resolution, comprising the following steps: providing two display panels, one of which is a single-axis grating panel, and the other is an active matrix panel, an active matrix The panel defines the gate line as the longitudinal driver, the source line (s〇urce line) as the lateral drive (r〇w Drivers), and the scan shutter through the single-axis raster panel (Scan Shutter). Sequential scanning is performed in synchronization with the onescan line of the active matrix panel; and a backlight is always turned on, so that the naked eye presents a 3D stereoscopic display effect. The features and implementations of the present invention are described in detail with reference to the preferred embodiments.

A single-axis grating panel 30 scans for an active matrix panel that defines a different direction of the gate line & source line than the conventional one, because the definition of the post-ranking is only considered to switch to color (2D). ·· RGB ; 3D : Take GGBB). Figure 6 is a schematic diagram of the driving method for enhancing the brightness of 3D stereoscopic display of the present invention. The scanning rate is 120 Hz, and the display frequency is 6 〇Ήζ, each of which is QVGA. For example, the resolution of (240xRGBx320) is 1/120x320/320 for each frame (Fra_). The switching time of the data is ι/ΐ2〇χι/32〇, and the data of 200812368 is 1/120x319. /320, the enhanced no-resolution loss of the present invention 3 The D display technology is achieved by the concept of Temporal Division Multiplex (TDM) and Spatial Division Multiplex (SDM). The sequential scanning is turned on and off, and the time division multiplexing and separation are performed. The multiplexed system controls the data output by the data driving chip, and the sequential scanning system scans sequentially in the longitudinal direction. Taking the present invention as an example, the switching of the opening and closing of the specific grating (Shutter) is sequentially performed from right to left. The mechanism will make the backlight always on, without waiting for a full page scanning, so as to maintain the brightness performance in 3D display, and solve the disadvantage that the conventional driving method leads to a decrease in the brightness of the overall 3D display. The preferred embodiments are disclosed above, but are not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
