Stereoscopic display driving method

The present invention relates to a driving method, and more particularly to a driving method of a stereoscopic display.

With the advancement and development of science and technology, people's enjoyment of material life and spiritual level has always increased and never decreased. On the spiritual level, in this era of rapid technological change, people hope to achieve the imaginative effect of stereoscopic displays through stereoscopic displays; therefore, how to make stereoscopic images or stereoscopic images become stereoscopic images. Today's stereoscopic display technology is the desired goal.

In the current display technology, the stereoscopic display technology can be roughly divided into a stereoscopic view in which an observer wears special design glasses and an auto-stereoscopic view that is directly viewed by the naked eye. Among them, the glasses-type stereo display technology has been developed and matured, and is widely used in some special applications such as military simulation or large-scale entertainment, but the glasses-type stereo display technology makes such technology due to its convenience and comfort. Not easy to popularize. Therefore, the naked-eye stereoscopic display technology has gradually developed and become a new trend.

A stereoscopic display of the prior art is disposed in front of the liquid crystal display panel by using a fixed grating, so that the observer's left eye and right eye respectively see the image corresponding to the display screen. It is worth noting that when the fixed raster is used as the processing mechanism of the stereo image, the viewer sees the screen as dividing the display screen into left and right eye image display areas, which is a spatial-multiplexed Way, although it can make the LCD panel It has the effect of stereoscopic display, but greatly reduces the resolution of the stereoscopic display.

1A and 1B are diagrams for explaining a display mechanism of another conventional stereoscopic display. Referring first to FIG. 1A, the stereoscopic display 100 is mainly composed of a liquid crystal display panel 110 and a grating 120. The liquid crystal display panel 110 has a plurality of staggered first pixel groups P1 and second pixel groups P2, and the grating 120 has a plurality of first light valve regions G1 and a plurality of second lights arranged in a staggered manner. Valve area G2. The first pixel group P1 and the second pixel group P2 are respectively composed of one pixel P.

As shown in FIG. 1A, in the first time fa (shown in FIG. 1C), the first light valve region G1 of the grating 120 is in a light blocking state, and the second light valve region G2 is in a light transmitting state, so that observation The right eye U _R and the left eye U _L pass through the second light valve area G2 in the light transmitting state, respectively, and respectively view the right eye picture displayed by the second pixel group P2 and the left side displayed by the first pixel group P1. Eye picture.

Next, as shown in FIG. 1B, in the second time fb (shown in FIG. 1C) immediately after the first time fa (shown in FIG. 1C), the first light valve region G1 of the grating 120 is in the light transmission. The second light valve area G2 is in a light blocking state, so that the observer's right eye U _R and left eye U _L pass through the first light valve area G1 in the light transmitting state, respectively, and the first pixel group P1 is viewed. The displayed right eye picture and the left eye picture displayed by the second pixel group P2. Therefore, after experiencing the first time and the second time, the observer can see the complete stereoscopic image due to the effect of persistence of vision.

It is worth mentioning that the switching frequency of the grating 120 can be adjusted according to the screen update frequency of the liquid crystal display panel 110, so that the liquid crystal display panel When the stereoscopic display is presented, the original resolution is maintained. For example, when the display frequency of the liquid crystal display panel 110 is 60 Hz, the operating frequency of the grating 120 may be 120 Hz. In other words, when the frame time of the liquid crystal display panel 110 is one-sixtieth of a second, the first time and the second time can be adjusted to one hundred and twenty-one second, so that the two phases in the liquid crystal display panel 110 During the adjacent frame time, the light transmission state and the light interruption state of the grating are instantaneously switched, so that the observer sees the complete number of pixels P in the original frame time of the liquid crystal display panel 110 to maintain the original analysis. degree. However, such a method easily causes a problem that the reaction time of the pixel P in the stereoscopic display 100 is insufficient, thereby affecting the contrast, brightness, display uniformity, and the like of the stereoscopic display.

In detail, FIG. 1C is a schematic diagram of driving waveforms of the pixels of the stereoscopic display 100 during display, wherein the pixels P can be used to respectively represent the first pixel group P1 and the second group used in FIG. 1A and FIG. 1B. Picture group P2. Referring to FIG. 1C, when each pixel P of the stereoscopic display 100 performs stereoscopic image display, the frame time F for displaying a stereoscopic image may be divided into three sub-frame times f1, f2, and f3, wherein the first sub-frame The time f1 is mainly the data input time. In the first sub-frame time f1, the scan lines S corresponding to the pixels P of the liquid crystal display panel 110 are sequentially input with the turn-on voltage Vgh, and the data voltages Vd are borrowed. Each pixel P is input from the corresponding data line D such that the pixel P has the pixel voltage Vp, and at this time, the backlight B assumes a closed state. Then, the second sub-frame time f2 is mainly the reaction time of the liquid crystal molecules. In the second sub-frame time f2, the liquid crystal molecules (not shown) located above the respective pixels P are different according to the pixel voltage Vp. Cheng The rotation of the degree, and at this time, the backlight B remains in the off state.

The third sub-frame time f3 is the image display time. In the third sub-frame time f3, a voltage V _{on is} input to the backlight B to illuminate the backlight B. Moreover, at least the state of the grating 120 is switched during the third sub-frame time f3, for example, the first light valve region G1 in FIGS. 1A and 1B is converted from a light blocking state to a light transmitting state, or a second light. The valve area G2 is converted into a light blocking state by a light transmitting state. In other words, the third sub-frame time f3 of the two adjacent frame times F is set to a first time fa and a second time fb, respectively, to be in the two adjacent frame times F. The stereo image presented in the third sub-frame time f3.

In order to further improve the display quality of the stereoscopic display, in the conventional driving method of the stereoscopic display, the third sub-frame time f3 is increased by shortening the first sub-frame time f1 and the second sub-frame time f2. In other words, in the conventional driving method, the display time of the image is increased by shortening the data input time and the reaction time of the liquid crystal molecules, so as to improve the contrast, brightness, and display uniformity of the stereoscopic display.

However, as the resolution of the stereoscopic display and the frequency of image update increase, the above-mentioned conventional technique of shortening the data input time of each pixel to increase the image display time will make it impossible for the pixel to complete the input corresponding data in a limited time. The problem of voltage means that it is easy to cause a problem that the charging rate of the pixel is insufficient. In detail, the efficiency of the pixel input data voltage is limited by the carrier mobility of the corresponding thin film transistor, so that the pixel cannot complete the input of the data voltage within a limited data input time, thereby affecting the stereoscopic display. Display quality, such as contrast reduction, brightness is not Just wait.

Referring to FIG. 2 and FIG. 3 simultaneously, the stereoscopic display 200 includes a liquid crystal display panel 210, a grating 220, and a backlight B. In this embodiment, the liquid crystal display panel 210 is disposed between the grating 220 and the backlight B. In other embodiments, The grating 220 may be disposed between the liquid crystal display panel 210 and the backlight B.

(not shown) electrical connection.

2 and FIG. 3, the pixel P is divided into a first pixel group P1 and a second pixel group P2 which are arranged in a staggered manner. In this embodiment, the first pixel group P1 and the second pixel group P2 are respectively composed of a single pixel P. In other embodiments, the first pixel group P1 and the second pixel group P2 may also be They are composed of three pixels P, such as red pixels, green pixels, and blue pixels, and the present invention is not limited thereto. In addition, the grating 220 has a plurality of first light valve regions G1 and second light valve regions G2 corresponding to the pixels P, wherein the first light valve region G1 and the second light valve region G2 may respectively exhibit a light blocking state or light passing through status. It is worth mentioning that the size and the number of the first light valve area G1 and the second light valve area G2 can be adjusted according to the distance between the grating 220 and the liquid crystal display panel 210, so that the user can pass the light through the presentation. The image of the corresponding first pixel group P1 and the second pixel group P2 is observed in the first light valve area G1 or the second light valve area G2 of the state.

In addition, in the embodiment, the light blocking state or the light passing state of the first light valve area G1 and the second light valve area G2, the user can determine the first light valve area G1 and the second light valve area through circuit control. G2's light blocking state or light passing state. In this embodiment, when the first light valve area G1 and the second light valve The region G2 is defined as the first grating state when it is in the light passing state and the light passing through the blocking state, respectively. Moreover, when the first light valve region G1 and the second light valve region G2 are respectively in a light blocking state and a light passing state, it is defined as a second grating state, and the state of the grating 220 shown in FIG. 2 is a second grating state.

Referring to FIG. 3, the present invention displays a frame time F of a stereoscopic image to define a plurality of sub-frame time f, and each pixel P can provide the same drive multiple times in different sub-frame times f. The voltage causes the first pixel group P1 and the second pixel group P2 to perform a plurality of charging procedures in a plurality of sub-frame times f, respectively, in other words, each pixel P is segmented in a plurality of sub-frame times f The method gradually approaches the data voltage of each pixel. Moreover, during the last sub-frame time f, a voltage Von is simultaneously supplied to illuminate the backlight B. In addition, in order to enable the stereoscopic display 200 to present a stereoscopic image, at least one first grating state time fG1 and at least one second grating state time fG2 are further defined in the last sub-frame time f by switching the first light valve region. The state of G1 and the second light valve area G2 allows the user to see a stereoscopic image during the last sub-frame time f. After that, turn off backlight B again.

In detail, referring to FIG. 3, in the present embodiment, the frame time F is divided into three sub-frame times f1, f2, and f3, and the same is applied to each of the sub-frame times f1, f2, and f3. The first data voltage V1 and the same second data voltage V2 to the first pixel group P1 and the second pixel group P2, such that the first pixel voltage Va of the first pixel group P1 and the second pixel group P2 The second pixel voltage Vb gradually approaches the first data voltage V1 and the second data voltage V2 in a segmented manner in the three sub-frame times f1, f2, and f3, respectively. For example, in the first sub-frame time f1, sequentially apply The voltage Vgh is turned to the scan line, as shown by the scan lines S1 to Sn in FIG. 3, and the first data voltage V1 and the second data voltage V2 are sequentially input into the first column in different columns by the corresponding data lines D1 and D2, respectively. The pixel group P1 and the second pixel group P2 are such that the first pixel voltage Va and the second pixel voltage Vb are Va1 and Vb1 respectively after the first sub-frame time f1, and then the shutdown voltage is sequentially applied. Vg1 to scan line S1~Sn, complete the first sub-frame time f1. At this time, the liquid crystal molecules in the liquid crystal layer 212 (shown in FIG. 2) start to rotate to different degrees according to the corresponding first pixel voltage Va1 and the second pixel voltage Vb1, respectively.

Then, in the second sub-frame time f2 immediately after the first sub-frame time f1, the turn-on voltage Vgh is sequentially applied to the scan lines S1 to Sn, and the same first data voltage V1 is sequentially and again The same second data voltage V2 continues to input the first pixel group P1 and the second pixel group P2 in different columns by the corresponding data lines D1 and D2, respectively, so that the first pixel voltage Va1 and the second pixel are The voltage Vb1 is further boosted to Va2 and vb2 respectively by the recharging process, wherein the first pixel voltage Va2 and the second pixel voltage Vb2 will be closer to the first data voltage V1 and the second data input corresponding to the data lines D1 and D2. Voltage V2. Thereafter, the off voltage Vg1 is sequentially applied to the scan lines S1 to Sn. At this time, the liquid crystal molecules in the liquid crystal layer 212 (shown in FIG. 2) continue to rotate to different degrees according to the corresponding first pixel voltage Va2 and the second pixel voltage Vb2, respectively.

Then, at the third sub-frame time f3, the turn-on voltage Vgh is sequentially applied to the scan lines S1 to Sn, so that the same first data voltage V1 and the same second data voltage V2 are sequentially continued by the data lines. Input bit The first pixel group P1 and the second pixel group P2 in different columns are caused to have the first pixel voltage Va3 and the second pixel voltage Vb3 substantially equal to the first data voltage V1 and the second data via a recharging procedure. After the voltage V2, the turn-off voltage Vg1 is sequentially applied to the scan lines S1 to Sn. At this time, the liquid crystal molecules in the liquid crystal layer 212 (shown in FIG. 2) are in a substantially stable state according to the corresponding first pixel voltage Va3 and the second pixel voltage Vb3.

In this way, when the backlight B is simultaneously illuminated at the third sub-frame time f3, the user does not see the image presented by the liquid crystal molecules during the rotation process, thereby preventing the user from seeing the picture blur. . On the other hand, since the first pixel group P1 and the second pixel group P2 respectively undergo a plurality of charging procedures, the first pixel voltage Va3 and the second pixel voltage Vb3 can be more advanced than conventional ones. The first data voltage V1 and the second data voltage V2 are input near the original, thereby increasing the contrast of the stereoscopic display 200. It is worth mentioning that the user can further adjust the sub-frame time f number divided in the frame time F or the sub-frame time f1, f2, f3 depending on the carrier mobility of the thin film transistor and the type of liquid crystal molecules. The length is such that the first pixel group P1 and the second pixel group P2 after the multiple charging process have better display quality.

In addition, it is worth noting that, in order to enable the stereoscopic display 200 to present a stereoscopic image, in the third sub-frame time f3, at least one first raster state time f _G1 and at least one second grating are further defined. Status time f _G2 . By switching the first raster state of the grating 220 and the second raster state, the user sees the stereoscopic image during the third sub-frame time f3. 4A and FIG. 4B are schematic diagrams showing a display state of the stereoscopic display using the driving method of FIG. 3, wherein FIG. 4A and FIG. 4B respectively represent the stereoscopic display 200 at the first raster state time f _G1 and the second raster state time f _{G2 .} Schematic diagram of the display mechanism.

Referring to FIG. 4A, the grating 220 is in the first grating state. In other words, the first light valve region G1 and the second light valve region G2 are respectively in a light passing state and a light blocking state, so that the light provided by the backlight B passes through the first a pixel group P1 and a first light valve region G1 transmit the left eye image to the left eye U _{L of the} user, and cause the light provided by the backlight B to pass through the second pixel group P2 and the first light valve region G1. Pass the right eye image to the user's right eye U _R .

Next, referring to FIG. 4B, the grating 220 is in the second grating state, in other words, the first light valve region G1 and the second light valve region G2 are respectively in a light blocking state and a light passing state, so that the light provided by the backlight B is provided. The right eye picture is transmitted to the right eye U _{R of the} user through the first pixel group P1 and the second light valve area G2, and the light passes through the second pixel group P2 and the first light valve area G1 to transmit the left eye picture. To the user's left eye U _L . Next, backlight B is turned off. Therefore, referring to FIG. 3 simultaneously, after undergoing an adjacent first grating state time f _G1 and a second grating state time f _G2 , the left eye U _{L of the} user will see the complete result due to the effect of the visual persistence. The left eye picture, while the right eye U _R will see the full right eye picture. After combining the images seen by the left eye U _L and the right eye U _R , the user can see a stereoscopic image.

It should be noted that the switching frequency of the light blocking state and the light passing state of the grating 220 can be adjusted according to the screen update frequency of the liquid crystal display panel 210. In this embodiment, the switching period of the grating 220 and the last sub-frame time are adjusted. f (for example, sub-frame time f3) is synchronized, wherein the switching period is, for example, the same as the length of the first raster state time f _G1 or the second raster state time f _G2 , so that the stereoscopic display 200 can maintain the original when presenting the stereoscopic image Resolution. For example, when the picture update frequency of the liquid crystal display panel 210 is 60 Hz, the third sub-frame time f3 is, for example, 180 Hz, and the state switching frequency of the grating 220 is operable at 60 Hz. In other words, when the picture update period of the stereoscopic image of the liquid crystal display panel 210 is substantially one-sixth of a second, the sub-frame times f1, f2, and f3 are, for example, substantially one hundred and eighty-one seconds. The state switching period of the time grating 220 may be synchronized with the sub-frame time f1, f2, f3. In other words, the state switching period of the grating 220 may be adjusted to one-sixtieth of a second, and the state switching period of the grating 220 is in FIG. For the first raster state time f _G1 , the state switching period of the raster 220 is the second raster state time f _G2 in the next frame time F, so that the user has the last sub-frame time of the two adjacent frames at time F In f3, the light passing state and the light blocking state of the grating 220 are instantaneously switched. For example, the grating 220 located above in FIG. 3 presents a light passing state before the first grating state time f _G1 , and the grating 220 located below is further The light passing state is presented in the second raster state time f _G2 , so that after the user experiences the first frame time F and the second frame time F, the observer can see the complete stereo image due to the effect of the visual persistence. . And maintain the resolution of the stereo image.

Based on the above, the present invention can solve the problem that the data voltage input efficiency is limited by the carrier mobility caused by the carrier mobility in the prior art, in other words, the pixels in the stereoscopic display are multi-charged by the driving method of the present invention. The effect is that the image presented by the stereoscopic display approaches the original data voltage setting value, so the invention has the advantages of avoiding distortion of the stereoscopic display screen and improving the contrast of the stereoscopic display. In addition, the backlight The lighting time is selected in the third sub-frame time when the liquid crystal molecules are in a stable state, so that the problem of blurring of the screen can be solved, and the display quality of the stereoscopic display can be improved.

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.
