Abstract
Description
Technical Field
[0001] This application belongs to the field of display, specifically relating to a driving module and a display device. Background Technology
[0002] When an LCD displays an image, the data lines provide data voltage to the pixel electrodes. Reversing the polarity causes the data voltage to alternate, meaning the data voltage can be greater or less than the voltage of the common electrode. The coupling capacitance (Cdc) formed between the data lines and the pixel electrodes causes a shift in the data voltage, resulting in crosstalk and affecting the display quality of the LCD.
[0003] Pulling up the source driver chips in even-numbered columns makes the display areas controlled by these chips polarity symmetrical with those controlled by the odd-numbered columns, forming a polarity-symmetrical mode. This ensures that the data voltage and common voltage coupling directions of adjacent display areas are opposite, thus canceling coupling and improving or eliminating crosstalk. However, in this polarity-symmetrical mode, at the boundary of adjacent display areas, entire columns of pixels may be either entirely positive or negative, while the polarity of sub-pixels in other areas alternates between positive and negative in the row and column directions. This causes the pixel columns at the boundary to be brighter or darker than other areas, forming bright or dark lines, which affects the display panel's display effect.
[0004] In existing technology, liquid crystal displays (LCDs) perform polarity reversal once per frame. Shortening the polarity reversal interval, for example, performing polarity reversal once every two lines, can improve or eliminate bright and dark lines. However, while shortening the polarity reversal interval is effective in compensating for non-full-pixel images, it can easily produce horizontal lines in full-pixel displays, affecting the display quality of the LCD.

[0050] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.
[0051] Example 1
[0052] See Figures 1 to 4 As shown, in this embodiment, the drive module 10 includes multiple source drive chips 100 (including... Figure 1 The display panel 20 includes C1~C4), a timing controller 200 (TCON), and at least one drive module 300. Each drive module 300 controls one display partition 21 of the display panel 20. Each source driver chip 100 is connected to multiple rows of data lines 213 of the display panel 20, i.e., multiple source driver chips 100 form multiple rows.
[0053] The driving module 300 includes a polarity partition control unit 310, a screen detection unit 320, a pixel detection unit 330, a column direction inversion control unit 340, and a row direction inversion control unit 350. The source driver chips 100 of odd-numbered columns are connected to a pull-down power supply 410, which includes a ground terminal. The source driver chips 100 of even-numbered columns are connected to a pull-up power supply 420 via the polarity partition control unit 310, where the voltage of the pull-up power supply 420 is greater than the voltage of the pull-down power supply 410. The polarity partition control unit 310 controls the even-numbered column source driver chips 100 to connect to the pull-down power supply 410 to form a normal polarity mode, or it controls the even-numbered column source driver chips 100 to connect to the pull-up power supply 420 to form a symmetrical polarity mode.
[0054] The screen detection unit 320 is connected to the display partition 21 and the polarity partition control unit 310. The screen detection unit 320 outputs a first control signal S1 to control the polarity partition control unit 310 based on the display screen of the display partition 21. When the crosstalk level of the detected display screen exceeds a set value, the first control signal S1 output by the screen detection unit 320 is a high-level control signal, which controls the polarity partition control unit 310 to switch to a polarity symmetry mode. If the crosstalk level of the detected display screen does not exceed the set value, the first control signal S1 output by the screen detection unit 320 is a low-level control signal, which controls the polarity partition control unit 310 to switch to a normal polarity mode.
[0055] Taking the "Zigzag" architecture display panel 20 as an example, the display panel 20 includes multiple columns of data lines 213 and multiple sub-pixels 214 arranged in an array. Each column of sub-pixels 214 is located between two adjacent data lines 213. That is, there is one more column of data lines 213 than sub-pixels 214. The sub-pixels 214 in odd-numbered rows are connected to the data lines 213 on the first side of the adjacent data lines 213 in their respective columns, and the sub-pixels 214 in even-numbered rows are connected to the data lines 213 on the second side of the adjacent data lines 213 in their respective columns. For example, the first side is the right side and the second side is the left side. The sub-pixels 214 in odd-numbered rows are connected to the data lines 213 on the right side of the adjacent data lines 213 in their respective columns, and the sub-pixels 214 in even-numbered rows are connected to the data lines 213 on the left side of the adjacent data lines 213 in their respective columns. The polarity inversion method of the display panel 20 is dot inversion, that is, the polarity of the sub-pixels 214 alternates between positive and negative in both the row and column directions.
[0056] The default state is the normal polarity mode. The pull-down power supply 410 outputs a low-level control signal to the odd-numbered column source driver chips 100, and the polarity of the first display sub-area 211 controlled by the odd-numbered column source driver chips 100 is "+-+-". The polarity partition control unit 310 controls the even-numbered column source driver chips 100 to disconnect from the pull-up power supply 420, and the pull-down power supply 410 outputs a low-level control signal to the even-numbered column source driver chips 100, and the polarity of the second display sub-area 212 controlled by the even-numbered column source driver chips 100 is "+-+-", such as... Figure 2 As shown.
[0057] In polarity symmetry mode, the polarity of the first display sub-area 211 controlled by the source driver chip 100 of the odd-numbered columns remains unchanged. The polarity partition control unit 310 controls the source driver chip 100 of the even-numbered columns to be connected to the pull-up power supply 420. The pull-up power supply 420 outputs a high-level control signal to the source driver chip 100 of the even-numbered columns. The polarity of the second display sub-area 212 controlled by the source driver chip 100 of the even-numbered columns becomes "-+-+". The adjacent display sub-areas of the display panel 20 are polarity symmetrical, such as... Figure 3As shown. It should be understood that the adjacent first display sub-region 211 and second display sub-region 212 are polar symmetrical, and the data voltage and common voltage of the first display sub-region 211 and the second display sub-region 212 are coupled in opposite directions, which can cancel the coupling and improve or eliminate crosstalk.
[0058] See Figure 3 As shown, in the polarity symmetry mode, the pixel column at the junction of the first display sub-area 211 and the second display sub-area 212 will have the entire column being either positive or negative polarity. Meanwhile, the row and column direction sub-pixels 214 in other areas of the first display sub-area 211 and the second display sub-area 212 will have alternating positive and negative polarities, causing the pixel column at the junction to become brighter or darker than other areas, thus forming a bright-dark line, which affects the display effect of the display panel 20.
[0059] To reduce or eliminate bright and dark lines, this embodiment also includes a pixel detection unit 330, a column direction inversion control unit 340, and a row direction inversion control unit 350, which are used to control the polarity inversion interval of the column and row directions of the display partition 21.
[0060] The pixel detection unit 330 is connected to the display partition 21, the column direction inversion control unit 340, and the row direction inversion control unit 350. The pixel detection unit 330 outputs a second control signal S2 to control the column direction inversion control unit 340 and the row direction inversion control unit 350 based on the display screen of the display partition 21. When the pixel detection unit 330 detects that the display screen is not a full-pixel screen, the second control signal S2 output by the pixel detection unit 330 is a high-level control signal; when the display screen is a full-pixel screen, the second control signal S2 output by the pixel detection unit 330 is a low-level control signal. A full-pixel screen means that the red sub-pixel (R), green sub-pixel (G), and blue sub-pixel (B) are all illuminated; a non-full-pixel screen means that at least one of the red, green, and blue sub-pixels, 214, is not illuminated.
[0061] The column orientation inversion control unit 340 is connected to the timing controller 200, the screen detection unit 320, the pixel detection unit 330, and all the source driver chips 100 of the display partition 21. When the displayed screen is not a full-pixel screen, the pixel detection unit 330 controls the column orientation inversion control unit 340 to work, so that the polarity of the display partition 21 is reversed every two rows, that is, the polarity of each column of sub-pixels 214 alternates between "++--" (V2line).
[0062] The horizontal direction inversion control unit 350 is connected to the timing controller 200, the screen detection unit 320, the pixel detection unit 330, and all the source driver chips 100 of the display partition 21. When the display screen is a full-pixel screen, the pixel detection unit 330 controls the horizontal direction inversion control unit 350 to work, so that the polarity of the data lines 213 of the display partition 21 is reversed every two columns, that is, the polarity of each row of sub-pixels 214 alternates between "++--" (H-2dot).
[0063] The image detection unit 320 outputs a high-level control signal, switching display partition 21 to polarity symmetry mode. If the displayed image is not a full-pixel image, the pixel detection unit 330 outputs a high-level control signal, and the column direction inversion control unit 340 controls the display partition 21 to perform polarity inversion every two rows, that is, the polarity of each column of sub-pixels 214 alternates between "++" and "--", and the pixel columns at the boundary will show alternating positive and negative polarities, such as... Figure 4 As shown, this can weaken or eliminate the light and dark lines.
[0064] The column orientation reversal control unit 340 controls the display partition 21 to reverse the polarity every two rows. This provides good compensation for non-full-pixel images, but it can easily produce horizontal lines for full-pixel displays, affecting the display effect of the LCD. Therefore, if the displayed image is a full-pixel image, the pixel detection unit 330 outputs a low-level control signal to control the row orientation reversal control unit 350 to reverse the polarity of the data lines 213 of the display partition 21 every two columns. That is, the polarity of each row of sub-pixels 214 alternates between "++--", in order to reduce or eliminate horizontal lines and improve the display effect of the LCD.
[0065] It should be noted that although this embodiment uses a "Zigzag" architecture and a dot inversion method for polarity reversal in the display panel 20 for illustration, the driving module 10 in this embodiment can also be used to drive display panels 20 with other architectures and inversion methods. As long as there are display panels 20 with the same positive or negative polarity in the entire column of pixels at the boundary of adjacent display sub-areas in the polarity symmetry mode, the driving module 10 disclosed in this embodiment can be used for driving.
[0066] In this embodiment, the driving module 10 includes multiple source driver chips 100, a timing controller 200, and at least one driving module 300. Each source driver chip 100 is connected to multiple rows of data lines 213 of the display panel 20. The driving module 300 includes a polarity partition control unit 310, a screen detection unit 320, a pixel detection unit 330, a column direction inversion control unit 340, and a row direction inversion control unit 350. The screen detection unit 320 controls the polarity partition according to the crosstalk severity of the display partition 21 of the display panel 20. The control unit 310 operates to form a normal polarity mode and a polarity symmetry mode. In the polarity symmetry mode, if the displayed image is not a full-pixel image, the pixel detection unit 330 controls the column direction reversal control unit 340 to reverse the polarity of every two rows of the display partition 21, so as to reduce or eliminate bright and dark lines. If the displayed image is a full-pixel image, the pixel detection unit 330 controls the row direction reversal control unit 350 to reverse the polarity of every two columns of the data lines 213 of the display partition 21, so as to reduce or eliminate horizontal lines and improve the display effect of the display panel 20.
[0067] In some embodiments, under normal polarity mode, the pixel detection unit 330 controls the row direction inversion control unit 350 to operate, so that the polarity of each column of data lines 213 in the display partition 21 is inverted. Simultaneously, the pixel detection unit 330 controls the column direction inversion control unit 340 to operate, so that the polarity of each frame in the display partition 21 is inverted. For example, in the current frame, the polarity of the data signals output by multiple data lines 213 in the row direction is sequentially "+-+-", and in the next frame, the polarity of the data signals output by multiple data lines 213 in the row direction is sequentially "-+-+".
[0068] The polarity of each column of data lines 213 in display partition 21 is reversed. The polarity reversal method of display partition 21 is dot reversal, which can better suppress screen flicker. At the same time, the polarity of all sub-pixels 214 is reversed once every frame, alternating the direction of the electric field, which can effectively avoid the polarization of liquid crystal molecules.
[0069] In some embodiments, the polarity partition control unit 310 includes a first transistor 311 and a resistor 312. A first terminal of the first transistor 311 is connected to a pull-up power supply 420, and a second terminal of the first transistor 311 is connected to a pull-down power supply 410 via the resistor 312. The control terminal of the first transistor 311 is connected to the image detection unit 320. The first transistor 311 includes an N-type field-effect transistor.
[0070] When the crosstalk level of the detected display screen exceeds a set value, the screen detection unit 320 outputs a high-level control signal, the first transistor 311 turns on, and the voltage output of the pull-up power supply 420 is sent to the even-numbered source driver chips 100, thus pulling up the even-numbered source driver chips 100; when the crosstalk level of the detected display screen does not exceed the set value, the screen detection unit 320 outputs a low-level control signal, the first transistor 311 turns off, and the voltage output of the pull-down power supply 410 is sent to the even-numbered source driver chips 100, thus pulling down the even-numbered source driver chips 100.
[0071] Switching between conventional polarity mode and polarity symmetry mode is achieved by using a transistor and a resistor 312, which simplifies the structure of the polarity partition control unit 310 and reduces the manufacturing cost of the drive module 10.
[0072] In some embodiments, the screen detection unit 320 is a waveform recognition unit, which is connected to the common electrode and polarity partition control unit 310 of the display partition 21. The waveform recognition unit controls the polarity partition control unit 310 to switch to a polarity symmetry mode when the voltage of the common electrode exceeds a preset range. When the voltage of the common electrode does not exceed the preset range, the waveform recognition unit controls the polarity partition control unit 310 to switch to a normal polarity mode.
[0073] Crosstalk causes data voltage shifts, which can lead to voltage fluctuations in the common electrode (Vcom). The waveform recognition unit sets a range based on the common electrode voltage (Vcom), i.e., sets positive and negative trigger values m1 and m2, respectively. Figure 5 As shown, when the voltage Vcom of the common electrode is detected to exceed the preset range (greater than m1 or less than m2, indicating severe crosstalk and poor image quality), a high-level control signal is output to the source driver chip 100 of the even-numbered column. Display partition 21 switches to polarity symmetry mode, and the data voltages of adjacent first display sub-regions 211 and second display sub-regions 212 are coupled in opposite directions to the common voltage, thereby canceling the coupling and improving or eliminating crosstalk. Conversely, when the voltage Vcom of the common electrode does not exceed the preset range, display partition 21 is in normal polarity mode.
[0074] When the display panel 20 displays special images, such as Excel images (images resembling Excel spreadsheets), alternating black and white columns, and TXT text documents, crosstalk can easily occur. The image detection unit 320 can also detect the severity of crosstalk based on parameters such as the type of image displayed and the area of the image prone to crosstalk. Furthermore, the image detection unit 320 can be an additional detection unit, but it is not limited to this; the image detection unit 320 can also be integrated into the timing controller 200, depending on the specific circumstances.
[0075] The image detection unit 320 is a waveform recognition unit. The waveform recognition unit judges the severity of crosstalk based on the voltage fluctuation of the common electrode, which reduces the difficulty of recognizing the severity of crosstalk.
[0076] In some embodiments, the column direction inversion control unit 340 includes a second transistor 341, a third transistor 342, and a frequency converter 343. The second transistor 341 includes an N-type field-effect transistor, and the third transistor 342 includes a P-type field-effect transistor. The control terminals of the second transistor 341 and the third transistor 342 are both connected to the pixel detection unit 330.

[0077] The horizontal direction inversion control unit 350 includes a fourth transistor 351, a fifth transistor 352, and an inverter 353. The fourth transistor 351 includes an N-type field-effect transistor, and the fifth transistor 352 includes a P-type field-effect transistor. The control terminals of the fourth transistor 351 and the fifth transistor 352 are both connected to the pixel detection unit 330.

[0078] The image detection unit 320 outputs a low-level control signal, switching display partition 21 to normal mode. The second transistor 341 is turned off and the third transistor 342 is turned on. The first polarity inversion control signal S3 generated by the timing controller 200 is directly output to all source driver chips 100 of display partition 21, causing display partition 21 to invert polarity every frame. At the same time, the fourth transistor 351 is turned off and the fifth transistor 352 is turned on.

[0079] The image detection unit 320 outputs a high-level control signal, and the display partition 21 switches to polarity symmetry mode. If the displayed image is not a full-pixel image, the pixel detection unit 330 outputs a high-level control signal, the second transistor 341 turns on and the third transistor 342 turns off. The first polarity reversal control signal S3 generated by the timing controller 200 is frequency-converted by the frequency converter 343, generating a first polarity reversal control signal S3 with increased frequency, which is output to all source driver chips 100 of the display partition 21, causing the polarity of the display partition 21 to be reversed every two rows. At the same time, the fourth transistor 351 turns on and the fifth transistor 352 turns off, and the second polarity reversal control signal S4 generated by the timing controller 200 is directly output to all source driver chips 100 of the display partition 21, causing the polarity of the data lines 213 of the display partition 21 to be reversed every column.

[0081] Both the column direction reversal control unit 340 and the row direction reversal control unit 350 are implemented with two transistors, which simplifies the structure of the drive module 300 and reduces the manufacturing cost of the drive module 10.
[0082] In some embodiments, see Figure 6As shown, the horizontal direction inversion control unit 350 also includes a sixth transistor 354, a seventh transistor 355, and an eighth transistor 356. Both the sixth transistor 354 and the eighth transistor 356 are N-type field-effect transistors, and the seventh transistor 355 is a P-type field-effect transistor. The control terminal of the sixth transistor 354 is connected to the pixel detection unit 330. The first terminal of the sixth transistor 354 is connected to the second terminal of the fourth transistor 351, and the second terminal of the sixth transistor 354 is connected to all the source driver chips 100 of the display partition 21. The control terminal of the seventh transistor 355 is connected to the screen detection unit 320. The first terminal of the seventh transistor 355 is connected to the timing controller 200, and the second terminal of the seventh transistor 355 is connected to all the source driver chips 100 of the display partition 21.

The first terminal of the eighth transistor 356 is connected to the second terminal of the fifth transistor 352, and the second terminal of the eighth transistor 356 is connected to the inverter 353.
[0083] The image detection unit 320 outputs a low-level control signal, switching display partition 21 to normal mode. The second transistor 341 is turned off and the third transistor 342 is turned on. The first polarity inversion control signal S3 generated by the timing controller 200 is directly output to all source driver chips 100 of display partition 21, causing display partition 21 to invert polarity every frame. At the same time, the fourth transistor 351, the sixth transistor 354, and the eighth transistor 356 are all turned off, and the seventh transistor 355 is turned on. The second polarity inversion control signal S4 generated by the timing controller 200 is directly output to all source driver chips 100 of display partition 21, causing the polarity of each column of data lines 213 of display partition 21 to invert polarity.
[0084] The image detection unit 320 outputs a high-level control signal, and the display partition 21 switches to polarity symmetry mode. If the displayed image is not a full-pixel image, the pixel detection unit 330 outputs a high-level control signal, the second transistor 341 turns on and the third transistor 342 turns off. The first polarity reversal control signal S3 generated by the timing controller 200 is frequency-converted by the frequency converter 343, generating a first polarity reversal control signal S3 with increased frequency, which is output to all source driver chips 100 of the display partition 21, causing the polarity of the display partition 21 to be reversed every two rows. At the same time, the fifth transistor 352 and the seventh transistor 355 turn off, and the fourth transistor 351 and the sixth transistor 354 turn on. The second polarity reversal control signal S4 generated by the timing controller 200 is directly output to all source driver chips 100 of the display partition 21, causing the polarity of the data lines 213 of the display partition 21 to be reversed every column.
[0085] The image detection unit 320 outputs a high-level control signal, switching display partition 21 to polarity symmetry mode. If the displayed image is a full-pixel image, the pixel detection unit 330 outputs a low-level control signal, the second transistor 341 is turned off and the third transistor 342 is turned on. The first polarity inversion control signal S3 generated by the timing controller 200 is directly output to all source driver chips 100 of display partition 21, causing display partition 21 to invert polarity every frame. At the same time, the sixth transistor 354 and the seventh transistor 355 are turned off, and the fourth transistor 351 and the eighth transistor 356 are turned on. The second polarity inversion control signal S4 generated by the timing controller 200 is output to all source driver chips 100 of display partition 21 through inverter 353, causing the data lines 213 of display partition 21 to invert polarity every two columns.
[0086] Adding a sixth transistor 354, a seventh transistor 355, and an eighth transistor 356 enables polarity reversal for each column of the data lines 213 of the display partition 21 in the normal polarity mode.
[0087] In some embodiments, the pixel detection unit 330 includes a first detection converter 331 and a ninth transistor 332, the ninth transistor 332 being an N-type field-effect transistor. The first detection converter 331 outputs a high-level control signal when it detects that the displayed image is not a full-pixel image, and outputs a low-level control signal when it detects that the displayed image is a full-pixel image. The control terminal of the ninth transistor 332 is connected to the first detection converter 331, the first terminal of the ninth transistor 332 is connected to the image detection unit 320, and the second terminal of the ninth transistor 332 is connected to the column direction inversion control unit 340 and the row direction inversion control unit 350.
[0088] When the screen detection unit 320 outputs a high-level signal and the display partition 21 is in polarity symmetry mode, the ninth transistor 332 turns on and uses the output signal of the screen detection unit 320 as the second control signal S2 to control the column direction reversal control unit 340 and the row direction reversal control unit 350, which can avoid the column direction reversal control unit 340 and the row direction reversal control unit 350 switching control signals in the normal polarity mode.
[0089] It should be noted that the control terminal of the ninth transistor 332 is connected to the first detection converter 331, the first terminal of the ninth transistor 332 is connected to the screen detection unit 320, and the second terminal of the ninth transistor 332 is connected to the column direction inversion control unit 340 and the row direction inversion control unit 350. However, it is not limited to this. The control terminal of the ninth transistor 332 is connected to the screen detection unit 320, the first terminal of the ninth transistor 332 is connected to the display partition 21, and the second terminal of the ninth transistor 332 is connected to the column direction inversion control unit 340 and the row direction inversion control unit 350 through the first detection converter 331.
[0090] The ninth transistor 332 controls whether the first detection converter 331 performs detection. The first detection converter 331 outputs a control signal as the second control signal S2 to control the column direction reversal control unit 340 and the row direction reversal control unit 350, which can avoid the column direction reversal control unit 340 and the row direction reversal control unit 350 switching control signals in the normal polarity mode.
[0091] In some embodiments, see Figure 7 As shown, the driving module 300 includes an anomaly detection unit 360, which includes a second detection converter 361 and a tenth transistor 362. The tenth transistor 362 includes an N-type field-effect transistor. The second detection converter 361 is connected to the display partition 21. The second detection converter 361 can determine the degree of brightness and darkness of the bright and dark lines based on the brightness and / or refresh rate of the display partition 21. When the degree of brightness and darkness of the bright and dark lines of the display partition 21 exceeds a preset value, the second detection converter 361 outputs a high-level control signal; when the degree of brightness and darkness of the bright and dark lines of the display partition 21 does not exceed the preset value, the second detection converter 361 outputs a low-level control signal. The control terminal of the tenth transistor 362 is connected to the second detection converter 361. The first terminal of the tenth transistor 362 is connected to the display partition 21, and the second terminal of the tenth transistor 362 is connected to the pixel detection unit 330.
[0092] In polar symmetry mode, not all images will produce bright and dark lines, and the brightness and darkness of the bright and dark lines produced by different images are different. For example, pure color low grayscale images are prone to producing bright and dark lines, and the higher the refresh rate of display zone 21, the more obvious the bright and dark lines are. The brightness and refresh rate are used to determine the brightness and darkness of the bright and dark lines. When the brightness is lower than the set value and / or the refresh rate is higher than the set value, the tenth transistor 362 is turned on. This can prevent the column direction inversion control unit 340 and the row direction inversion control unit 350 from switching control signals when no obvious bright and dark lines are produced.
[0093] In some embodiments, see Figure 8 and Figure 9 As shown, the drive module 10 includes multiple drive modules 300. The column direction inversion control unit 340 of each drive module 300 is connected to all the source drive chips 100 it controls via a first signal line 430. The timing controller 200 is connected to the column direction inversion control unit 340 via a second signal line 440. The row direction inversion control unit 350 of each drive module 300 is connected to all the source drive chips 100 it controls via a third signal line 450. The timing controller 200 is connected to the row direction inversion control unit 350 via a fourth signal line 460.
[0094] The drive module 10 includes multiple selectors 500 and a selection controller 600. Each selector 500 includes an eleventh transistor 510 and a twelfth transistor 520. The eleventh transistor 510 includes a P-type field-effect transistor, and the twelfth transistor 520 includes an N-type field-effect transistor.
[0095] The first and second terminals of the eleventh transistor 510 of the partial selector 500 are respectively connected to the first signal line 430 of the adjacent display partition 21, and the first and second terminals of the eleventh transistor 510 of the partial selector 500 are respectively connected to the third signal line 450 of the adjacent display partition 21. The first and second terminals of the twelfth transistor 520 of the partial selector 500 are respectively connected to the second signal line 440 of the adjacent display partition 21, and the first and second terminals of the twelfth transistor 520 of the partial selector 500 are respectively connected to the fourth signal line 460 of the adjacent display partition 21. One of the second signal lines 440 is connected to the timing controller 200, and one of the fourth signal lines 460 is connected to the timing controller 200.
[0096] The control terminals of the eleventh transistor 510 and the twelfth transistor 520 are both connected to the selection controller 600. The selection controller 600 can output a high-level control signal or a low-level control signal to control each display partition 21 individually by a drive module 300 or to control all display partitions 21 uniformly by a drive module 300.
[0097] When most display zones 21 are full-pixel or non-full-pixel images, the multiple display zones 21 of the entire display panel 20 can be uniformly controlled by a single drive module 300 to reduce the power consumption of the drive module 10; when the display zones 21 with full-pixel images are similar to those with non-full-pixel images, each display zone 21 is independently controlled by a single drive module 300 to achieve a better display effect.
[0098] In some embodiments, the driving module 10 includes at least three driving modules 300. A selection controller 600 is connected to the pixel detection unit 330 of each driving module 300. When the number of received high-level control signals or low-level control signals is greater than a preset value, the selection controller 600 outputs a high-level control signal to control all display zones 21 to be uniformly controlled by one driving module 300; otherwise, it outputs a low-level control signal so that each display zone 21 is controlled by one driving module 300 respectively. For example, the driving module 10 includes three driving modules 300. When the number of received high-level control signals or low-level control signals is greater than or equal to 2, the selection controller 600 outputs a high-level control signal to control all display zones 21 to be uniformly controlled by one driving module 300.
[0099] By determining whether to control uniformly or separately based on the control signal output by the pixel detection unit 330, the complexity of selecting the controller 600 can be reduced, and the manufacturing cost of the drive module 10 can be reduced.

The polarity partition control unit 310 operates to form a normal polarity mode and a polarity symmetry mode. In the polarity symmetry mode, if the displayed image is not a full-pixel image, the pixel detection unit 330 controls the column direction reversal control unit 340 to reverse the polarity of every two rows of the display partition 21, so as to reduce or eliminate bright and dark lines. If the displayed image is a full-pixel image, the pixel detection unit 330 controls the row direction reversal control unit 350 to reverse the polarity of every two columns of the data lines 213 of the display partition 21, so as to reduce or eliminate horizontal lines and improve the display effect of the display panel 20 and the display device.
