Description

Drive device and drive method

The present invention relates to an apparatus and method, and more particularly to a driving apparatus and driving method.

Liquid crystal displays (LCDs) are often used as display devices based on their ability to display high-quality images with a little power. In the liquid crystal display, the liquid crystal molecules have a certain alignment based on their long and flat molecular structures, and the alignment of the liquid crystal molecules has an important role in determining the light transmittance in the liquid crystal cells of the liquid crystal panel.

In general, if a high voltage is supplied between the liquid crystal layers for a certain period of time, the optical transmission characteristics of the liquid crystal molecules will change. The foregoing changes may be permanent changes that may result in deterioration of the display quality of the irreversible liquid crystal display panel. In order to avoid deterioration of the quality of the liquid crystal molecules, the plurality of voltage signals supplied to the liquid crystal cells must be continuously changed. Typically, the source driver is configured according to a polarity inversion method (eg, frame polarity inversion, column polarity inversion, row polarity inversion, point polarity inversion, and two-line polarity inversion) to produce alternating polarity Voltage signal.

In the case of a liquid crystal display using a zigzag configuration, it is possible to employ line polarity inversion. Under this architecture, when the liquid crystal display displays a white or black picture, the power consumption of the liquid crystal display is low. However, when the liquid crystal display displays a solid color or a complementary color picture, the picture has a transition phenomenon, resulting in a transition phenomenon. The power consumption of the liquid crystal display increases.

It can be seen that the above existing methods obviously have inconveniences and defects, and need to be improved. In order to solve the above problems, the relevant fields have not tried their best to find a solution, but for a long time, no suitable solution has been developed.

In order to solve the problem that the power consumption of the display device is increased due to the phenomenon of the pulse transition, the embodiment of the present invention provides a driving device and a driving method, which are described together with the drawings.

FIG. 1 is a schematic diagram of a display device according to an embodiment of the invention. As shown, the display device includes a drive device 100, a data drive 200, and a display panel 500. Further, the driving device 100 includes a clock controller 110 and a gate driver 120 for driving the display panel 500.

In detail, the display panel 500 includes a plurality of pixels 510, 520, ..., a plurality of scanning lines 501 to 508, and a plurality of data lines 531 to 537. Further, the pixel 510 includes sub-pixels 510R, 510G, and 510B, and the pixels 520 include sub-pixels 520R, 520G, and 520B, and the sub-pixels 510R to 520B are arranged in a sub-picture as shown in FIG. Prime array. In addition, the scan lines 501-508 and the data lines 531-537 are electrically coupled to corresponding sub-pixels, respectively. For example, the six paintings on the first column The connection relationship is as follows: the secondary pixels 510R/G/B and 520R/G/B are connected to the first scan line 501, but the data lines connected by each pixel are different, for example, the secondary pixel 510R is connected to the data line 532. The sub-pixel 510G connection data line 533, the sub-pixel 510B connection data line 534, the sub-pixel 520R connection data line 535, the sub-pixel 520G connection data line 536, and the sub-pixel 510B connection data line 537. The six sub-pictures on the second column are as follows: the sub-pixels 510R/G/B and 520R/G/B are connected to the second scan line 502, but the data lines connected to each sub-pixel are different, such as : sub-pixel 510R connection data line 531, sub-pixel 510G connection data line 532, sub-pixel 510B connection data line 533, sub-pixel 520R connection data line 534, sub-pixel 520G connection data line 535 and sub-pixel 510B Connect the data line 536. The last pixel connection relationship of the different columns in the subsequent sequence is connected and analogized according to the above connection manner. For example, the secondary pixels on the third column are all connected to the third scan line 503, and the corresponding data is The line connection relationship uses the first column of pixels and the data line connection mode, and the secondary pixels on the fourth column are connected to the fourth scan line 504, and the second column is used in connection with the corresponding data line. The way the pixels are connected to the data lines, and the sub-pixels on the subsequent columns are analogized. It can be seen from the above that the connection relationship between the sub-pixels on different columns but on the same line and the corresponding data lines (for example, data lines 531 and 532) will appear staggered, that is, zigzag.

When the embodiment of the present invention is implemented, the display panel 500 can be, but not limited to, a liquid crystal display (LCD), a light-emitting diode (LED) panel, and an organic light-emitting diode (Organic). Light-Emitting Diode, OLED) panel, plasma display Panel (Plasma Display Panel, PDP), ..., etc. Any person skilled in the art in the spirit of the embodiments of the present invention can selectively implement the present invention by appropriately adopting appropriate elements in accordance with actual needs.

As described above, when implementing the embodiments of the present invention, several different situations are usually generated, and they are respectively controlled by adaptive means, and the above will be described in detail below. In the case that the display panel 500 is used to display a white or black picture, since all the secondary pixels are fully bright or completely dark, if the general gate driver outputs a control signal and sequentially scans the scan lines 501 to 508, the data is When the line transmits data to the number of times of drawing, no pulse conversion phenomenon occurs. However, in the case where the display panel 500 is used to display a solid color or a complementary color picture, if a general gate driver outputs a control signal and sequentially scans the scan lines 501 to 508, the data lines 531 to 537 transmit data to the sub-pixels. In the process, a pulse conversion phenomenon occurs at the intersection of the sub-pixels of the odd-numbered columns and the even-numbered columns (hereinafter referred to as the parity alternating state).

From this, it can be seen that the above-described pulse switching phenomenon occurs when a general gate driver is used and is applied to the scanning lines 501 to 508 as a whole by using a conventional control method. Accordingly, the present invention configures the driving device 100 in the display device, which includes the clock controller 110 and the corresponding gate driver 120, and can control the order of scanning the scan lines 501-508 by adaptive means, respectively. To solve the problem caused by the pulse conversion phenomenon.

Specifically, when an image is to be displayed through the display panel 500, the clock controller 110 determines the image and outputs a first control signal or a second control signal according to the determination result of the image. Therefore, the gate driver 120 can adaptively sweep according to the first control signal. The scan lines 501-508 are traced, or the gate driver 120 can adaptively scan a set of odd scan lines in a first cycle and a set of even scan lines in a second cycle according to a second control signal.

Therefore, the gate driver 120 can sequentially scan the scan lines 501 to 508 without special control to save the control cost of specifically controlling the scan order. However, the gate driver 120 can still be adapted in another case. Sexually, different scanning modes are used in the two cycles, so that in the process of completely scanning the display panel 500, only the pulse switching phenomenon caused by the parity transition condition is present in the data lines 531-537 to reduce the display device. power consumption.

The adaptive control of the gate driver 120 described above includes several different implementations, which are separately explained below.

In an implementation manner, if the clock controller 110 determines that the image is white or black, the clock controller 110 outputs a first control signal according to the image determination result, and then, in this case, the data line 531~ 537 does not generate a pulse conversion. Therefore, the gate driver 120 sequentially scans the scan lines 501 to 508 according to the first control signal, and does not require special manipulation.

Furthermore, if the clock controller 110 determines that the image is a solid color or a complementary color, the clock controller 110 outputs a second control signal according to the image determination result, and then, in this case, the data lines 531 to 537 are transmitted. In the process of data to the number of times of painting, there will be a phenomenon of parity transition occurring, which leads to pulse conversion. At this time, an adaptive control method is needed to control the scanning order of the scanning lines. The upper open scan sequence is exemplarily illustrated in the 2A and the 2B is a diagram showing a waveform of a control signal outputted by the gate driver 120 shown in Fig. 1 of the present invention, and a second diagram showing a pulse transition of the data line shown in Fig. 1 of the present invention. It should be noted that, referring to FIG. 1 and FIG. 2A together, the first scan line 501 outputs the scan signal G1, the second scan line 502 outputs the scan signal G2, the third scan line 503 outputs the scan signal G3, and so on. .

As shown in FIG. 1, when the data driver 200 drives a pure red picture in one picture period, the output data lines 531, 533, and 535 respectively supply the negative pixel data to the corresponding pixels, and output the same. Data lines 532, 534, and 536 provide positive polarity pixel data to corresponding pixels, respectively. Referring to FIG. 2A, the gate driver 120 adaptively outputs the scan signals G1 and G3 in the first period T1 according to the second control signal to scan the first scan line 501 and the third scan line 503 and in the second period. T2 sequentially outputs scan signals G2, G4 to scan the second scan line 502 and the fourth scan line 504.

In this embodiment, in addition to the above condition, the gate driver 120 scans the scan lines in the first period T1 and the second period T2 according to the second control signal, and the gate driver 120 further performs the second control signal according to the second control signal. The scan signals G6, G8 are sequentially output in the third period T3 to scan the sixth scan line 506 and the eighth scan line 508, and the scan signals G5, G7 are sequentially output in the fourth period T4 to scan the fifth scan line 505. And a seventh scan line 507. The first period T1, the second period T2, the third period T3, and the fourth period T4 belong to the same picture period. Referring to FIG. 2B, in accordance with the scanning mode of the gate driver 120, the gate driver 120 is completed. During the scanning of the display panel 500, only a small number of parity transitions occur in the data lines 531-537, resulting in a pulse switching phenomenon, thereby reducing the power consumption of the display device. Further, when the pure red picture is driven, the data lines 532, 534, and 536 are only switched to the second period T2 during the first period T1, and the parity is alternated when the third period T3 is switched to the fourth period T4. The pulse switching phenomenon can reduce the power consumption of the display device. In this way, compared with the gate driver 120, the sequential scanning method is completely adopted, thereby reducing the power consumption of the display device by 50%.

In addition, referring to FIG. 2B, when driving the pure red picture, the data line 531 provides a low-level negative data signal 201 in the first to fourth periods T1 to T4. The data line 532 provides a high level positive polarity data voltage 202 to the pixels corresponding to the first scan line 501 and the third scan line 503 in the first period T1, and the data line 532 provides the low level positive level in the second period T2. The data voltage 202 is given to the pixels corresponding to the second scan line 502 and the fourth scan line 504, and the data line 532 provides the low level positive data voltage 202 to the sixth scan line 506 and the third period T3. The pixels of the eight scan lines 508, and the data lines 532 provide the high-level positive data voltage 202 to the pixels corresponding to the fifth scan line 505 and the seventh scan line 507 in the fourth period T4.

Next, the data line 533 provides a low level negative data signal 203 in the first to fourth periods T1 to T4. The data line 534 provides a low-level positive data voltage 204 to the pixels corresponding to the first scan line 501 and the third scan line 503 in the first period T1, and the data line 534 provides a high-level positive electrode in the second period T2.

The negative polarity data voltage 205 of the bit is given to the pixels corresponding to the second scan line 502 and the fourth scan line 504, and the data line 535 provides the negative polarity data voltage 205 of the low level to the sixth scan line in the third period T3. 506 and the pixels of the eighth scan line 508, and the data line 535 provides a high-level negative data voltage 205 to the pixels corresponding to the fifth scan line 505 and the seventh scan line 507 in the fourth period T4.

In addition, the data line 536 provides a low level positive polarity data signal 206 in the first to fourth periods T1 to T4. The data line 537 provides a low-level negative data voltage 207 to the pixels corresponding to the first scan line 501 and the third scan line 503 in the first period T1, and the data line 537 provides a high-level negative electrode in the second period T2. The data voltage 207 is given to the pixels corresponding to the second scan line 502 and the fourth scan line 504, and the data line 537 provides the high-level negative data voltage 207 at the third period T3 to correspond to the sixth scan line 506 and the first The pixels of the eight scan lines 508, and the data lines 537 provide the low-level negative data voltage 207 to the pixels corresponding to the fifth scan line 505 and the seventh scan line 507 in the fourth period T4.

In another implementation, if the clock controller 110 determines that the image is white or black, the clock controller 110 outputs a first control signal according to the image determination result, and similarly, no special manipulation is required.

Furthermore, if the clock controller 110 determines that the image is a solid color (for example, red, green, or blue) or a complementary color (for example, magenta, cyan, or yellow), the clock controller 110 outputs the image according to the image determination result. The second control signal, similarly, because in this case, the data lines 531-537 are in the process of transmitting data to the number of times of painting, there will be a parity transition phenomenon that causes a pulse conversion phenomenon, and at this time, adaptive control is required.

In detail, referring to FIGS. 1 and 3A, the first scan line 501 outputs the scan signal G1, the second scan line 502 outputs the scan signal G2, the third scan line 503 outputs the scan signal G3, and so on.

As shown in FIG. 3A, the gate driver 120 adaptively outputs the scan signals G1, G3, G5, and G7 in the first period T1 according to the second control signal to scan the first scan line 501 and the third scan line 503. The fifth scan line 505 and the seventh scan line 507 sequentially output the scan signals G2, G4, G6, and G8 in the second period T2 to scan the second scan line 502, the fourth scan line 504, the sixth scan line 506, and the Eight scan lines 508, wherein the first period T1 and the second period T2 belong to the same picture period. Subsequently, please refer to FIG. 3B, in accordance with the adaptive scanning mode of the gate driver 120 described above, the gate driving In the process of completely scanning the display panel 500, when the pure red picture is driven, the data lines 532, 534 and 536 will only have a parity transition when the data lines 532, 534 and 536 are switched to the second period T2 during the first period T1, resulting in a pulse conversion phenomenon. Thus, compared with the gate driver 120, the sequential scanning method is completely adopted, thereby reducing the power consumption of the display device by 75%.

In addition, the embodiment of the present invention further provides a driving method for driving the display panel 500 as shown in FIG. 1. In order to make the driving method easier to understand, please refer to FIG. 1 together. The driving method includes the following steps.

Therefore, the driving method can sequentially scan the scanning lines 501 to 508 without special control, thereby saving the control cost of specifically controlling the scanning order. However, the driving method can still be adaptively used in another case. In the process of completely scanning the display panel 500, there is only a pulse conversion phenomenon caused by the parity alternating condition in the data lines 531~537, so as to reduce the power consumption of the display device. .
