Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
It should be noted that although functional block division is performed in a device diagram and a logic sequence is shown in a flowchart, in some cases, the steps shown or described may be performed in a different order than the block division in the device, or in the flowchart. The terms first, second and the like in the description and in the claims and in the above-described figures, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the application only and is not intended to be limiting of the application.
With the rapid development of Mini LED display technology, the Mini LED display product is applied to super-large screen high-definition display, such as commercial fields of monitoring command, high-definition performance, high-end cinema, medical diagnosis, advertisement display, conference, office display, virtual reality and the like.
Currently, anodes of each row of LEDs in the horizontal direction of a Mini LED display panel are connected together, and cathodes of each column of LEDs in the vertical direction are connected together. When a row driving control signal is added to a row, whether each LED in the row is lit or not is determined by a column driving control signal applied to each column corresponding to the row. That is, the column driving control signals of the columns and the rows are required to control the light emission start time and the light emission end time of the LEDs on each row by switching the high and low levels, resulting in a high switching frequency of the high and low levels in the column driving control signals. For the driving mode of adjusting brightness by controlling the light emitting time of the LEDs through PWM (pulse width modulation) signals, the refresh rate is generally very high, and can easily reach several khz, and at this time, the horizontal switching of the on/off of the LEDs is higher by the column driving control signals, so that a large amount of extra power consumption is caused by parasitic capacitance on each column line of the display panel.
Referring to fig. 1, fig. 1 is a schematic diagram of a driving architecture of a mini LED display panel. As shown in fig. 1, the display panel 200 includes a plurality of row lines 210 and a plurality of column lines 220. Wherein the row line 210 is connected to the anode of each light emitting diode in the direction of the row line 210, and the column line 220 is connected to the cathode of each light emitting diode in the direction of the column line 220. Each row line 210 is input with a corresponding row driving voltage waveform signal. For example, the n-th row line 210 corresponds to the input row driving voltage waveform signal Gn, the n+1-th row line 210 corresponds to the input row driving voltage waveform signal gn+1, and the n+2-th row line 210 corresponds to the input row driving voltage waveform signal gn+2. Each column line 220 is input with a corresponding column driving voltage waveform signal. For example, the n-th column line 220 corresponds to the input column driving voltage waveform signal Sn, the n+1th column line 220 corresponds to the input column driving voltage waveform signal sn+1, and the n+2th column line 220 corresponds to the input column driving voltage waveform signal sn+2.
Referring to fig. 2, fig. 2 is a schematic diagram of a driving timing of a mini LED display panel. As shown in fig. 2, the curve OE is an enable output curve of the row driving voltage waveform signal curve Gn. Only when Gn is high and Sn is low, a voltage difference is formed between the anode and cathode of the light emitting diode on the nth row line and the nth column line, so that the light emitting diode emits light. The luminous intensity is determined by the luminous duration, and the longer the luminous duration is, the brighter the brightness is. Referring to fig. 2, gn outputs a high level category at time T1. At time T2, sn is pulled down to a low level species so that at time T2 Gn and Sn form a voltage differential, the led can emit light. I.e. the led starts to emit light at time T2. At time T3 Sn is pulled up to a high level species so that at time T3 Gn and Sn no voltage difference can be created and the led no longer emits light. I.e. the led ends emitting light at time T3. At time T4, gn is pulled down to a low level category, and the nth row line corresponding to Gn is turned off. As can be seen, for the nth row line, the light emitting diode is controlled to start to emit light by pulling down Sn to the low level type at time T2, and the light emitting diode is controlled to end to emit light by pulling up Sn to the high level type at time T3. That is, the light emission start time and the light emission end time of the n-th row line light emitting diode are both required to be realized by switching the Sn high and low level. Similarly, gn+1 outputs a high level category at time T5. At time T6, sn is pulled down to a low level species so that at time T6 gn+1 and Sn form a voltage differential, the light emitting diode can emit light. I.e. the led starts to emit light at time T6. At time T7 Sn is pulled up to a high level species so that at time T7 gn+1 and Sn no voltage difference can be formed and the led no longer emits light. I.e. the led ends emitting light at time T7. At time T8, gn+1 is pulled down to a low level type, and the n+1-th row line corresponding to gn+1 is turned off. It can be seen that for the n+1th row line, the light emitting diode is controlled to start to emit light by pulling down Sn to a low level type at time T6, and the light emitting diode is controlled to end to emit light by pulling up Sn to a high level type at time T7. That is, the light emission start time and the light emission end time of the n+1th row line light emitting diode are also required to be realized by switching the Sn high and low level. According to curve OE, the T2 and T6 positions are periodically constant, as are the T1 and T4 positions, with the time difference between T2 and T1 being equal to the time difference between T6 and T5.
In the driving method shown in fig. 2, the light emitting start time and the light emitting end time of the light emitting diodes on each row line need to be realized by switching the Sn high and low levels, so that the switching frequency of the high and low levels in the column driving control signal is high. For the driving mode of adjusting the brightness by controlling the light emitting time of the LEDs through the PWM signal, the refresh rate is generally very high, and can easily reach several khz, and at this time, the horizontal switching of the on/off of the LEDs is higher by the column driving control signal, so that a large amount of extra power consumption is caused by the parasitic capacitance on each column line of the display panel.
Based on the above, the embodiment of the application provides a driving method of a display panel. The method aims at controlling the light-emitting start time and the light-emitting end time of each LED on each row line through the row driving control signal and the column driving control signal, so that the switching frequency of high and low levels in the column driving control signal can be reduced while the row driving control signal is not changed, and the power consumption can be effectively reduced.
Referring to fig. 3, fig. 3 is a schematic block diagram of a driving apparatus for a display panel according to an embodiment of the present application. As shown in fig. 3, the display panel 200 includes row lines 210 and column lines 220, and the driving apparatus 100 includes a timing control module 110 and a driving module 120, wherein the driving module 120 is electrically connected to the timing control module 110, and the driving module 120 is electrically connected to the row lines 210 and the column lines 220 in the display panel 200.
In the embodiment of the present application, the driving module 120 can convert the row driving control signal sent by the timing control module 110 into the row driving voltage waveform signal Gn recognizable by the display panel 200, and simultaneously convert the column driving control signal sent by the timing control module 110 into the column driving voltage waveform signal Sn recognizable by the display panel 200. Accordingly, a corresponding row driving voltage waveform signal Gn may be input to the row line 210 of the display panel 200, and a column driving voltage waveform signal Sn corresponding to each column line 220 may be input to each column line 220 of the display panel 200. So that whether or not each light emitting diode on each row line 210 is turned on and the duration of the light emitting diode on each row line 210 can be determined by the row driving voltage waveform signal Gn corresponding to the row line 210 and the column driving voltage waveform signal Sn corresponding to each column line 220 on the row line.
It should be noted that, the row driving voltage waveform signal Gn is periodically and constantly changed, and the row driving voltage waveform signal Gn is simultaneously input from the left and right sides of the row line 210, so that it is possible to avoid the situation that the voltage at the anodes of the light emitting diodes on the same row line 210 is not equal due to the voltage loss caused when the voltage flows into the row line 210 from one end to the other end far from the inflow end.
It is understood that the display panel 200 is driven row by row, and when a row driving voltage waveform signal is input to the uppermost row line 210 of the display panel 200, a corresponding column driving voltage waveform signal is simultaneously input to each column line 220 on the row line 210. Thus, the lighting and the lighting time period of each led on the row line 210 can be controlled by inputting the row driving voltage waveform signal of the row line 210 and the column driving voltage waveform signal corresponding to each column line 220 on the row line 210. After the driving of the uppermost row line 210 of the display panel 200 is completed, the light emitting diodes on the next row line 210 are driven in the same manner.
Referring to fig. 4, fig. 4 is a flowchart of a driving method performed by a timing control module according to an embodiment of the present application. As shown in fig. 4, the driving method is performed by the timing control module 110 in the driving apparatus 100 shown in fig. 3, including but not limited to steps S410 to S430.
In step S410, data to be displayed is obtained, and a row driving control signal is generated according to the data to be displayed, wherein the row driving control signal carries a first light-emitting end time of an odd-numbered row line in the display panel and a second light-emitting start time of an even-numbered row line in the display panel.
In the embodiment of the present application, the timing control module 110 first obtains the data to be displayed, and then generates the corresponding row driving control signal by analyzing the data to be displayed. The row driving control signals mainly include a CPV (row driving conversion clock) signal, an STV (row driving start pulse) signal, and a OEV (gate row driving output enable) signal. The switching control of the TFT (thin film transistor) can be realized by changing the timing of the CPV signal, the STV signal, and the OEV signal, thereby controlling the display of an image. The generated row driving control signal may carry a first light emitting end time of an odd row line in the display panel 200 and a second light emitting start time of an even row line in the display panel. The LED is controlled to be non-conductive by switching the voltage from high to low, so that the light-emitting end time of each odd-numbered row line can be controlled. Meanwhile, the voltage difference between the anode and the cathode of the LED can be controlled by switching the voltage from low to high, so that the light-emitting starting time of each even row line can be controlled.
In step S420, a column driving control signal is generated according to the data to be displayed and the row driving control signal, where the column driving signal carries a first light-emitting start time of the odd-numbered row lines and a second light-emitting end time of the even-numbered row lines.
In the embodiment of the present application, after the timing control module 110 generates the row driving control signal according to the data to be displayed, the column driving control signal may be further generated according to the data to be displayed and the row driving control signal. The column driving control signals mainly include a CPH (column driving switching clock) signal, an STH (column driving start pulse) signal, and a OEH (column driving output enable) signal. Display control of the image can be achieved by changing the timing of the CPH signal, OEH signal, and STH signal.
It should be noted that, when the timing control module 110 generates the row driving control signal, the light emitting end time of each odd row line may be determined, so that the timing control module 110 may first obtain the corresponding light emitting duration according to the display data corresponding to each odd row line, and thus may reversely infer the light emitting start time of each odd row line according to the light emitting end time and the corresponding light emitting duration of each odd row line. Similarly, the timing control module 110 may determine the light emission start time of each even row line according to the generated row driving control signal, so that the timing control module 110 may first obtain the corresponding light emission time according to the display data corresponding to each even row line, so as to derive the light emission end time of each even row line according to the light emission start time and the corresponding light emission time of each even row line.
It should be noted that, after the timing control module 110 sends the row driving control signal to the driving module 120, the driving module 120 converts the row driving control signal into a row driving voltage waveform signal recognizable by the display panel 200, and then inputs the row driving voltage waveform signal to each row line 210 of the display panel 200. Similarly, after the timing control module 110 sends the column driving control signal to the driving module 120, the driving module 120 converts the column driving control signal into a column driving voltage waveform signal recognizable by the display panel 200, and then inputs the column driving voltage waveform signal to each column line 220 of the display panel 200.
Referring to fig. 5, fig. 5 is a diagram illustrating a driving timing of a display panel according to an embodiment of the present application. As shown in fig. 5, the curve OE is an enable output curve of the row driving voltage waveform signal curve Gn. The curve Gn is a row driving voltage waveform signal curve corresponding to the n-th row line, gn+1 is a row driving voltage waveform signal curve corresponding to the n+1th row line, and gn+2 is a row driving voltage waveform signal curve corresponding to the n+2th row line. Curve Sn is the column driving voltage waveform signal curve corresponding to the nth column line. Fixedly, gn outputs a high level category at time T1 and Gn is pulled down to a low level category at time T3. That is, the light emitting diode is turned off at time Gn, and the light emission of the n-th row line is ended. I.e. for the nth row line the light emitting end time of the light emitting diode is controllable by Gn. Therefore, the light-emitting starting time of the light-emitting diode on the nth row line can be reversely deduced only according to the light-emitting time of the data to be displayed and the light-emitting ending time. For example, by reversely pushing the light emitting diode on the nth row line to have the light emitting start time T2, the light emitting diode is pulled down to be of a low level type at the time Sn of T2, so that the anode and the cathode of the light emitting diode on the nth row line form a voltage difference, and the light emitting diode starts to emit light. Similarly, gn+1 outputs a high level type at time T4 and is pulled down to a low level type at time T6. That is, at time T4, gn+1 is high, sn is low, gn+1 and Sn form a voltage difference, and the light emitting diode starts to emit light. That is, for the n+1th row line, the light emission start timing of the light emitting diode can be controlled by gn+1. Therefore, the light emitting end time of the light emitting diode on the n+1th row line can be deduced only according to the light emitting time of the data to be displayed and the light emitting start time. For example, by pushing out that the light emitting end time of the light emitting diode on the n+1th row line is T5, the light emitting diode is pulled up to be of a high level type at the time Sn of T5, so that the anode and the cathode of the light emitting diode on the n+1th row line cannot form a voltage difference, and the light emitting diode ends. Wherein the time interval in which the voltage is switched from high to low or from low to high is periodically constantly changing for the row driving voltage waveform signal.
Step S430, a row driving control signal and a column driving control signal are sent to the driving module, so that the driving module performs light-emitting driving on each light emitting diode on each odd row line and each even row line in the display panel according to the row driving control signal and the column driving control signal.
In the embodiment of the present application, the timing control module 110 sends the row driving control signal and the column driving control signal to the driving module 120 after generating the row driving control signal and the column driving control signal. The driving module 120 may generate a row driving voltage waveform signal recognizable by the display panel 200 according to the row driving control signal. Meanwhile, the driving module 120 may generate column driving voltage waveform signals corresponding to each column line identifiable by the display panel 200 according to the column driving control signals. The driving module 120 transmits the row driving voltage waveform signals to each row line of the display panel 200 and transmits each column driving voltage waveform signal to each corresponding column line, so as to realize the light emitting driving of each light emitting diode on each odd row line and each even row line in the display panel 200.
In the embodiment of the present application, the timing control module 110 is configured to receive data to be displayed, and generate a row driving control signal that varies periodically and constantly according to the data to be displayed. The row driving control signal controls the light emission end time of each odd-numbered row line to be periodically constant, and the light emission start time of each even-numbered row line to be periodically constant. The timing control module 110 also generates a column driving control signal according to the data to be displayed and the row driving control signal, wherein the generated column driving control signal can control the light emitting start time of each odd-numbered row line and the light emitting end time of each even-numbered row line. Thus, after the timing control module 110 sends the row driving control signal and the column driving control signal to the driving module 120, the driving module 120 may generate a corresponding row driving voltage waveform signal according to the row driving control signal, and the driving module 120 may generate a column driving voltage waveform signal corresponding to each column line according to the column driving control signal, so that the driving module 120 may transmit the row driving voltage waveform signal to each row line of the display panel 200, and transmit each column driving voltage waveform signal to each corresponding column line, so as to implement light-emitting driving on each light-emitting diode on each odd row line and each even row line in the display panel 200.
In one embodiment of the present application, referring to fig. 6, fig. 6 is a flowchart of steps for generating column driving control signals according to data to be displayed and row driving control signals according to an embodiment of the present application. Is executed by the timing control module 110, including but not limited to steps S610 to S630.
Step S610, determining a first light emitting duration of each odd row line and a second light emitting duration of each even row line according to the data to be displayed;
step S620, determining a first lighting start time of each odd-numbered line according to the first lighting time and the first lighting end time of each odd-numbered line, and determining a second lighting end time of each even-numbered line according to the second lighting time and the second lighting start time of each even-numbered line;
in step S630, corresponding column driving control signals are generated according to the first light-emitting start time of each odd-numbered row line and the second light-emitting end time of each even-numbered row line.
In the embodiment of the present application, the timing control module 110 may determine the first light emitting duration corresponding to each light emitting diode on each odd-numbered row line and the second light emitting duration corresponding to each light emitting diode on each even-numbered row line by processing and analyzing the data to be displayed. The first light-emitting end time of each light-emitting diode on each odd-numbered row line can be determined through the row driving voltage waveform signals, so that the first light-emitting start time corresponding to each light-emitting diode on each odd-numbered row line can be reversely pushed according to the first light-emitting end time and the first light-emitting duration. Similarly, the second light-emitting starting time of each light-emitting diode on each even-numbered row line can be determined by the row driving voltage waveform signal, so that the second light-emitting ending time corresponding to each light-emitting diode on the even-numbered row line can be deduced according to the second light-emitting starting time and the second light-emitting duration. Thereby generating corresponding column driving control signals according to the deduced first light emitting start time of each odd-numbered row line and the deduced second light emitting end time of each even-numbered row line. So that the generated column drive control signals can be used to control the first light emission start times for each odd row line and the second light emission end times for each even row line.
For example, a high-frequency gray scale clock signal represents a gray scale, if the light emitting data in the data to be displayed is 10 bits, the total of 0-1023 gray scales is 1024 gray scales, the time is 1023 gray scale clocks, the rising of the row driving voltage waveform signal Gn is divided into 1023 parts, the rising of the row driving voltage waveform signal Gn is used as the light emitting starting time of the even row line, and the falling of the row driving voltage waveform signal Gn is used as the maximum time of the light emitting diode on the even row line. The column driving voltage waveform signal Sn is pulled down to a low level at the same time when the rising of the even row line up driving voltage waveform signal Gn starts. Then, according to the light emission data value, for example, 500, the column driving voltage waveform signal Sn is pulled high to a high level at a position of 500 gray scale clocks after the row driving voltage waveform signal Gn rises to end light emission. If the odd-numbered row lines need to convert the light-emitting data and emit light 500, the row driving voltage waveform signal Sn can be reversely pushed to pull down the row driving voltage waveform signal Gn to a low level at 523 gray scale clock positions after the row driving voltage waveform signal Gn rises, so that light emission starts at 523 gray scale clock positions, and when 500 gray scale clocks are passed, the row driving voltage waveform signal Gn is pulled down to a low level, so that light emission ends. Therefore, in the example of fig. 5, although the column driving voltage waveform signal Sn outputs a low voltage from the time T3 to the time T4, the light emitting diode cannot be turned on because the row driving voltage waveform signal Gn is turned off, and thus no power consumption is generated.
The embodiment of the application generates the corresponding column driving control signals through the data to be displayed and the pre-generated row driving control signals with periodical constant change, so that the light-emitting start time and the light-emitting end time of each light-emitting diode on each row line can be controlled by the row driving control signals and the column driving control signals together while the row driving control signals are not changed, the switching frequency of high and low levels in the column driving control signals can be reduced, and the power consumption can be effectively reduced.
In one embodiment of the present application, after transmitting the row driving control signal and the column driving control signal to the driving module, the driving method shown in fig. 4 further includes:
and sending a scanning control signal to the driving module so that the driving module can identify the odd-numbered row lines and the even-numbered row lines according to the scanning control signal.
In the embodiment of the present application, because the mini LED display panel is driven row by row in a line scanning manner from top to bottom or from bottom to top, after the timing control module 110 sends the row driving control signal and the column driving control signal to the driving module 120, the driving module 120 also needs to send the scanning control signal at the same time, so that the driving module recognizes the odd-numbered row lines and the even-numbered row lines according to the scanning control signal.
In the embodiment of the present application, since the driving module 120 can identify whether the current row line to be driven is an odd-numbered row line or an even-numbered row line according to the scan control signal, after outputting the row driving voltage waveform signal with a periodic constant variation, the corresponding column driving voltage waveform signal can be accurately generated according to the identified parity of the current row line to be driven according to the column driving control signal sent by the timing control module 110.
Illustratively, the clock control module 110 sends a 500 gray scale clock signal to the driving module 120, at this time, for even row lines, the column driving voltage waveform signal Sn is pulled high to end the light emission at 500 gray scale clocks after the row driving voltage waveform signal Gn rises. For the odd row lines, it indicates that the column driving voltage waveform signal Sn needs to be pulled down to a low level 500 gray scale clock positions after the row driving voltage waveform signal Gn rises, thereby starting light emission at 500 gray scale clock positions. It can be seen that for even row lines, the 500 gray scale clock signal transmitted by the timing control module 110 refers to pulling the column driving voltage waveform signal Sn high at the position of 500 gray scale clocks to end the light emission. For the odd-numbered row lines, the 500 gray scale clock signal transmitted by the timing control module 110 refers to pulling down the column driving voltage waveform signal Sn to a low level at a position of 500 gray scale clocks to start light emission.
Referring to fig. 7, fig. 7 is a flowchart of a driving method performed by a driving module according to an embodiment of the present application. As shown in fig. 7, the driving method is performed by the driving module 120 in the driving apparatus 100 shown in fig. 3, including but not limited to steps S710 to S740.

step S720, generating a row driving voltage waveform signal according to the row driving control signal;
step S730, generating column driving voltage waveform signals corresponding to the column lines according to the column driving control signals;
step S740, driving the light emitting diodes on each odd-numbered row line and each even-numbered row line of the display panel according to the row driving voltage waveform signal and the column driving voltage waveform signal corresponding to each column line.
In the embodiment of the present application, the execution body is the driving module 120, and after receiving the row driving control signal and the column driving control signal sent by the timing control module, the driving module 120 generates a row driving voltage waveform signal identifiable by the display panel 200 according to the row driving control signal, and generates a column driving voltage waveform signal corresponding to each column line identifiable by the display panel 200 according to the column driving control signal. Thus, the light emitting diodes on the odd-numbered row lines and the even-numbered row lines in the display panel 200 can be driven to emit light according to the row driving voltage waveform signal and the column driving voltage waveform signal corresponding to the column lines.
In the embodiment of the present application, the driving module 120 drives the display panel 200 mainly according to the row driving control signal and the column driving control signal sent by the timing control module 110. The driving module 120 further converts the row driving control signal into a row driving voltage waveform signal identifiable by the display panel 200, and converts the column driving control signal into a column driving voltage waveform signal corresponding to each column line identifiable by the display panel 200. Illustratively, when the timing control module 110 sends a row driving start pulse signal to the driving module 120, the driving module 120 generates a row driving voltage waveform signal that pulls up the level to a high level when the row driving start pulse signal is received, and the driving module 120 generates a row driving voltage waveform signal that pulls down the level to a low level when the row driving off command signal is received. Likewise, the driving module 120 may generate the column driving voltage waveform signal when receiving a 500 gray scale clock signal, and pull the voltage level high to the high level when receiving the 500 gray scale clock signal, so as to end the light emission. Alternatively, the driving module 120 may generate the column driving voltage waveform signal when receiving a 500 gray scale clock signal by pulling the voltage level low to start emitting light when receiving the 500 gray scale clock signal.

At this time, the driving module 120 inputs the row driving voltage waveform signal G1 to the 1 st row line, and simultaneously inputs the column driving voltage waveform signal S1 corresponding to the 1 st column line, the column driving voltage waveform signal S2 corresponding to the 2 nd column line, the column driving voltage waveform signal S3 corresponding to the 3 rd column line, and the column driving voltage waveform signal Sn corresponding to the nth column line. Namely, all n column lines on the 1 st row line are respectively corresponding column driving voltage waveform signals are input to the corresponding column lines so as to realize the light-emitting driving of all the light-emitting diodes on the 1 st row. And then shifting, inputting a row driving voltage waveform signal to the row line of the 2 nd row, and inputting column driving voltage waveform signals corresponding to all the column lines of the n columns on the row line of the 2 nd row to the corresponding column lines so as to realize the light-emitting driving of all the light-emitting diodes on the row line of the 2 nd.
