Description

201205545 x vowo^JXXZlTW 34508twf.doc/n VI. Description of the Invention: [Technical Field] The present invention relates to a driving method of a liquid crystal display panel, and more particularly to a method for driving a precharged liquid crystal display panel . At the same time, it relates to a driving method of a stereoscopic display device. [Prior Art] With the advancement of technology, in the development of display technology, in addition to pursuing the slimness and shortness of display devices, it is more desirable to achieve the goal of displaying stereoscopic aspects. In general, the principle of displaying a stereoscopic face is to send a left-eye image and a right-eye face that can form a stereoscopic face into the left and right eyes of the user, respectively, thereby causing the brain to construct a three-dimensional space. surface. Therefore, how to make a display device to present a stereoscopic image or image has become an extremely desirable target of today's display device technology. As far as the appearance is concerned, stereoscopic display technology can be roughly classified into stereoscopic and auto-stereoscopic. Among them, the glasses-type stereo display can be divided into color filter glasses, polarizing glasses, and shutter glasses. The working principle of the glasses-type stereo display is mainly to use the display device to send the left and right eye images with special information, and the left and right eyes respectively see the left and right eye images through the selection of the glasses matched with them to form stereoscopic vision. Nowadays, stereoscopic display with stereoscopic glasses has matured and is widely used in certain special applications, such as military simulation or large-scale entertainment. FIG. 1 is a schematic diagram of a conventional stereoscopic display device 1 including a display device 20 and glasses 30, and the open glasses 3 are controlled by wired 201205545 ---------^, 1TW 34508twf.doc/n or wirelessly. The right lens 32 (left lens 34) and the left lens 34 (right lens 32) are closed so that only the right eye (left eye) can receive the face, and FIG. 2 is the stereoscopic display device i of FIG. The timing chart of the time, in which the broken line represents the low level and is in the closed state, the solid line represents the operation of each component, and the higher than the dotted line indicates the high level and is in the open state. Referring to FIG. 1 and FIG. 2, the display device 2 can be a liquid crystal display device, including a liquid crystal display panel 22 and a backlight module 24, wherein the liquid crystal display panel 22 changes the arrangement of liquid insects by inputting a voltage. When you go to the position, you can display the correct light penetration and present the correct image. It is assumed that the face data transmitted by a signal source drives the display device 2 to update and display a single eye face in each frame rate T, and the liquid crystal display panel 22 only completes the single eye face in the update time TA. Update. As shown in the timing line of the display panel in Fig. 2, the left eye face is updated first, and the left lens 34 of the glasses 30 is opened in the blanking time TB following the update time TA. At this time, the backlight module 24 of the display device 20 is kept fully turned on, as shown in the timing line of the backlight module in FIG. 2, wherein the timing line is at a high level (solid line), and the backlight module is turned on. The low level (dashed line) represents the state in which the backlight module is off. Taking the single-eye scan frequency as 120 Hz as an example, 'T is 1/120 = 8.33 milliseconds, and the update time TA is 5.64 milliseconds. Since the facet displayed by the liquid crystal display panel 22 during the screen update process is not completely correct, it is not desirable to be seen by the user. Therefore, the right lens 32 and the left lens 34 of the glasses 30 are opaque within 5.64 milliseconds. The state is to prevent the user wearing the glasses 30 from seeing the face of the updated liquid crystal display panel 22 as shown in the right lens and the left lens of FIG. 2, 34508 twf.doc/n 201205545. The timing lines are all at a low level. Disabled. After the liquid crystal display panel 22 completes the updating of the left eyelid surface, the liquid crystal display panel 22 continues to display the updated left eye picture at the blank time TBr, while the backlight module 24 remains fully turned on to provide a backlight. In addition, the left lens 34 of the eyeglasses 30 is switched to the light transmitting state during the blanking time TB so that the left eye face displayed by the display device 20 can reach the left eye of the user. The right lens 32 of the eyeglasses 30 remains opaque during this blanking time TB' to prevent the left eye image displayed by the display device 2 from reaching the user's right eye. Following a similar procedure, the liquid crystal display panel 22 will update and display the right eye face within a frame rate T below the left eye face. The right eye face update is completed in the update time TA, and the updated right eye face is displayed at the subsequent blank time tb, and the backlight module 24 remains fully turned on to provide a backlight. The right lens 32 of the glasses 30 remains opaque during the update time, and is switched to the light transmitting state during the subsequent blanking time TB to enable the updated right eye face displayed by the display blasting 20 to reach the use. The right eye of the person. During the right eyelid update and display time, the left lens 34 of the glasses 30 remains opaque to prevent the right eye image displayed by the display device 20 from reaching the user's left eye. In the above manner, by using the phenomenon of persistence of vision, a user wearing glasses 3 can view a stereoscopic picture. However, since it takes a certain time for the liquid crystal to be reacted in place by the voltage, and the liquid crystal display panel 22 is normally scanned from the top to the bottom of the liquid crystal display panel 22, the liquid crystal under the liquid crystal display panel 22 will be later 201205545. Rv〇v〇7·?αλΖ 1TW 34508twf.doc/n drive, so it will happen that the glasses have been turned on 3 but the liquid crystal below the liquid crystal display panel 22 has not been reflected in place, so that the user may see the blank time ΤΒ β To the wrong image, that is, the residual image phenomenon (c-plane·_. Figure 3 shows the relationship between the scan line drive time and the liquid crystal reaction time, the first, the N/2th, and the nth scan line wait The time driven by the scan pulse signal P1 is tG, t1, and t2, respectively (t2 > u > (9), and after the scan pulse signal P1 is input and before the blank time TB, each of the scan lines is driven by the voltage and the liquid crystal is reactive. The lengths of time are in the order of TR0, TR1 and TR2. It can be seen from Fig. 3 that the later the scanned line is shorter due to the shorter response time, the liquid crystal cannot be transferred to the positioning time in the blanking time TB, so the silk is expressed. The present invention provides a method for driving a liquid crystal display panel, which can improve the image sticking phenomenon of the liquid crystal display panel. The present invention provides a driving method for a liquid crystal display panel. The liquid crystal display panel includes a scan line and a plurality of pixels, and Μ is a positive integer, and each scan line is connected to at least one pixel. The target gray scale value is driven by the first target voltage value.

In the embodiment of the present invention, the second leg is driven simultaneously during the second period. In the embodiment of the present invention, the scan line to the scan line are sequentially driven in the partial region 3 of the second portion. In the embodiment, wherein The step of driving the 扫描 scan line to the 昼 条 知 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到 到The default grayscale value. In an embodiment of the invention, the preset grayscale value is determined by the position of the scan line to which the reference pixel 34508twf.doc/n is connected and the first target grayscale value of the pixel. In an embodiment of the invention, the second target electric bunker value of the second picture of the liquid crystal display panel is further searched according to the second overdrive. In an embodiment of the invention, the second target pressure value of the second pupil is determined by reference to a preset grayscale value of each pixel and a second threshold value of the second pupil plane. In the embodiment of the present invention, the driving side of the liquid crystal display panel includes a liquid crystal display panel_light source in addition to the second period (4) of the partial section. In an embodiment of the invention, wherein the viewing device comprises two viewing windows, the driving method of the liquid crystal display panel further comprises controlling one of the viewing windows of the viewing device to be transparent during the second period of the partial interval. Light. In an embodiment of the invention, the first side surface and the second screen form a stereoscopic surface. Based on the above, the present invention utilizes the charging of the pixels of the liquid crystal display panel to the preset grayscale value in advance during the precharging of the kneading surface after the first screen is displayed, so as to reduce the time required for the liquid crystal to go to the positioning when the second kneading surface is displayed. Improve the image sticking phenomenon of the liquid crystal display panel. The above described features and advantages of the present invention will become more apparent from the description of the appended claims. [Embodiment] Referring to Figure 4, there is shown a schematic view of a stereoscopic display of an embodiment of the present invention. The stereoscopic display device 40A includes a liquid crystal display device 4〇2 and a controllable viewing device 4〇4 (for example, shutter glasses), wherein the liquid crystal display 201205545 * vwu^vXXZlTW 34508twf.doc/n device 402 further includes a liquid crystal display The panel 4〇3 and a backlight (not shown), wherein the viewing device 404 includes two viewing windows wi, W2, and the architecture of the liquid crystal display panel 403 is the same as that of the prior art, and details are not repeated herein. Fig. 5 is a flow chart showing a method of driving a stereoscopic display device and a liquid crystal display panel 403 according to an embodiment of the present invention. Fig. 6 is a timing chart showing the use of the driving method of Fig. 5 to display a stereoscopic surface, wherein the level of the timing diagram of Fig. 6 indicates whether or not the pixel data is fed into the pixel. The liquid crystal display panel 403 driven by the driving method comprises a plurality of scanning lines and a plurality of pixels, wherein each scanning line is connected to at least one element, and the first side surface representing the left eye face and the right eye side face are sequentially displayed. The second side of the face is matched with the viewing device 404, and the left and right eyelid faces can be sequentially transmitted to the corresponding eyes of the user, thereby allowing the user to construct a stereoscopic image. Referring to FIG. 4 to FIG. 6, the driving method of the liquid crystal display panel 403 includes the following steps. First, in step S502, in the first period TRE1, a plurality of scan lines on the liquid crystal display panel 403 are sequentially driven and input first target voltage values representing different gray scale values to drive the pixels on the respective scan lines. To the first φ target gray scale value to be displayed, a first picture is displayed on the liquid crystal display panel 403. However, since the process of the first facet conversion does not want to be seen by the user, the backlight of the liquid crystal display panel 403 is in the closed state during the first period TRE1, and the two viewing windows of the viewing device 404 are W2 is controlled in an opaque state. Next, in step S504, the second period THP of the subsequent first period TRE1 is entered, including a hold picture period τη and a precharge buffer period TP. During the holding period TH of the second period THP, the pixel voltage of each pixel on the liquid crystal display 9 34508 twf.doc/n 201205545 panel 403 will be maintained at the first of the first target gray scale value in the first period TRE1 The target voltage value is such that the liquid crystal display panel 403 continuously displays the first pupil face. While maintaining the kneading period τη, the backlight of the liquid crystal display panel 403 will be turned into an open state, and is turned on through the viewing window W2 of the viewing device 404, so that the user can see each of the liquid crystal display panels 403. A display surface composed of halogens having different gray scale values. For example, when the first screen is displayed on the liquid crystal display panel 403 and the first screen is the left-eye plane, the viewing window W1 corresponding to the left eye in the viewing device 404 is controlled to be in a light-transmissive state so that the left eye of the user can be The left eyelid surface is received, and the viewing window W2 corresponding to the right eye in the viewing device 404 is controlled to be in an opaque state to block the user's right eye from receiving the left eye image. Next, in step S506, the pixels on the liquid crystal display panel 403 are driven to a preset gray scale value in a partial interval in the second period THP, that is, in the precharge buffer period TP'. Then, in step S508, the third period TRE3 of the second period THP is further entered, and in the third period TRE3, the plurality of scan lines on the liquid crystal display panel 403 are sequentially driven and input with the values representing different gray scale values. a second target voltage value for driving the pixels on each scan line to the second target gray scale value to be displayed, and then displaying a second surface on the liquid crystal display panel 403, wherein the viewing device is in the third period TRE3 The two viewing windows of the 404 are controlled to be in an opaque state to prevent the conversion process from being seen by the user. Thus, the time required for the pixel to be charged to the second target gray scale value can be saved when the third period TRE3 of the second period THP is continued. During the pre-charging period TP, the backlight of the liquid crystal display panel 403 is turned off, and the two views of the viewing device 404 201205545. * v«w^JXXZlTW 34508twf.doc/n Windows W Bu W2 is also Controlled in an opaque state to avoid the process of conversion being seen by the user. Therefore, when the liquid crystal display panel 403 is applied to display a stereoscopic image, the first pupil plane and the second pupil plane may be the left eye pupil plane and the right eye pupil plane, respectively, and the viewing window W2 of the viewing device 404 is also respectively turned on. The user can view the left eye and the right eye in sequence to construct a stereoscopic image. Moreover, the pre-power-free picture period TP is preferably close to the third period TRE3 and maintains the picture period TH from the first period TRE1. For example, assuming that the gray scale value of the pixel on the liquid crystal display panel 403 can be 0 to 255, τρ can drive the gray scale value of the pixel to 128 during the precharged plane. In this way, when the gray scale value of the pixel has too large a transition (for example, 0-255 or 255-0), the liquid crystal display panel 403 has a residual image because the pixel cannot display the target grayscale value. The phenomenon. In this embodiment, although the preset grayscale value of the pixel is set to 128, the user can adjust the preset grayscale value according to the actual situation, for example, according to the range of the grayscale value or the overall display screen. Brightness adjusts the size of the preset grayscale value as long as it is not 0. It should be noted that, in this embodiment, the backlight of the liquid crystal display panel 403 is turned off during the first period TRE1, the pre-charging buffer period TP, and the third period TRE3 to prevent the user from seeing the grayscale value of the liquid crystal during the two periods. The process of conversion. Of course, it is also possible to simultaneously close the two viewing windows W1, W2 of the viewing device 404 to achieve the same effect. For example, when the liquid crystal display panel 403 using shutter glasses is used in the stereoscopic display technology, the backlight of the liquid crystal display panel 403 may be turned on in the first period TRE1, the second period THP, and the third period TRE3. At the same time, the shutter glasses are opened iZITW 34508twf.d〇c/n 201205545 and closed, so that the left and right eyes are simultaneously shielded, so that the user cannot see the process of gray scale value conversion of the liquid crystal, and by controlling the two glasses The order of opening and closing allows the user's eyes to receive corresponding pictures and construct a stereoscopic picture. In detail, the manner in which the pixels on the liquid crystal display panel 403 are precharged to the preset gray scale value in the above step S506 is, for example, simultaneously driving all the scan lines on the liquid crystal display panel 403 to simultaneously drive the respective scan lines. The morpheme, and adjust all the morphemes to the preset grayscale value. In other embodiments, the scan lines may be driven one by one to pre-charge the corresponding pixels on each scan line to a preset gray scale value. In order to avoid this kind of adjustment, some of the scan lines are late, so that the corresponding pixels can be charged to the preset gray level value at the pre-charged surface, which is charged at different time points. The pixel on the driven scan line is based on the first target gray scale value of the first screen (that is, the display screen during the hold period) = the same as the different overdrive voltage (〇ver Driving button (4), borrowed The relatively driving voltage causes the pixels on the liquid crystal display panel to be pre-charged, and the TP can be pre-charged to the preset grayscale value. In addition to the first target grayscale value of the first surface. In addition to the pre-charging, the driver 2 adjusts the voltage of t according to the second picture displayed by the third period TRE3. For example, when the second side is a brighter picture, the TP is desired during the pre-filling period. The preset gray scale value is increased. In contrast, if the face is a darker face, the preset gray scale value established during the precharged face is lowered. Among them, the drive time is different. Pre-charging of pixels on the scan line to pre-2012 201205545 tvov/o^jXXZITW 34 508twf.doc/n Set the grayscale value (4) The overvoltage value can be determined according to the Over Driving Look Up Table. As shown in Figure 7A, the overdrive lookup table has the left stop position indicating The first target gray scale value of the pixel in the picture, the upper block indicates the position of each scan line, where M is a positive integer, and varies with the resolution of the liquid crystal display panel 403. The Full-HD is For example, Μ is 108 (^ according to the first target grayscale value of each pixel in the first picture and the position of the corresponding scan line, the preset of each pixel being charged in the TP during the precharged picture period can be determined. Grayscale value. § During the third period, TRE3 can also use another overdrive lookup table to determine the overdrive voltage required to charge the pixel to the second side. The overdrive lookup table as shown, on the left The block indicates the preset grayscale value driven by the TP during the precharge screen, and the upper field indicates the second target grayscale value of the pixel, which can be determined based on the overdrive lookup table. Each of the pixels on the liquid crystal display panel 403 is charged to the third period TRE3 to The second target voltage value required for the two target gray scale values. It can be seen from the above that the TP and the third period TRE3 are applied to the halogen during the precharged rake period through the overdrive lookup table of FIG. 7A and FIG. 7B. The over-voltage of the liquid crystal display panel 403 can be charged and displayed on the pre-charge screen period TP and the third period TRE3. The phenomenon of image sticking occurs, and the display quality of the liquid crystal display panel 403 is lowered. The above embodiment is a method of pre-charging the pixels on all the scanning lines on the liquid crystal display panel 403 to avoid the occurrence of image sticking on the back surface. Not limited to this. In some embodiments, the pixel corresponding to the first scan line 13 201205545 rvowo^^^ZlTW 34508twf.doc/n may have sufficient reaction time to make the liquid crystal go to the preset gray scale value, so It is necessary to precharge the τρ during the precharge screen, and only the step of precharging the scan line having insufficient reaction time (that is, the scan line driven later in the first period TRE1) is required. For example, FIG. 8 is a timing chart showing a stereoscopic face when a driving method according to another embodiment of the present invention is used. It is assumed that the liquid crystal display panel 403 has 1024 scan lines, wherein the first 250 scan lines have sufficient reaction time when updating the display screen, so that the liquid crystal can be turned to the target gray scale 榼 state, and the later driven 774. The scanning line lacks sufficient reaction time. Therefore, during the pre-charging process, only the 774 scanning lines that are driven later are subjected to the above-described pre-charging step, and the detailed pre-charging method has been taught in the above embodiment, and therefore will not be described again. In summary, the present invention charges the pixels of the liquid crystal display panel to a preset gray scale value in a partial interval of the second period to reduce the time required for the liquid crystal to go to the positioning, and improve the image sticking phenomenon of the liquid crystal display panel. . The precharged pixel can be selectively defined as a pixel corresponding to a later driven scan line on the liquid crystal display panel to improve the power saving efficiency of the liquid crystal display panel. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
