Exemplarily, the liquid crystal display panel generally includes an upper substrate and a lower substrate which are aligned as well as liquid crystal molecules packaged between the upper substrate and the lower substrate. When a picture is displayed, since a voltage difference is between a data voltage loaded to a pixel electrode of each sub-pixel and a common electrode voltage on a common electrode, and the voltage difference may form an electric field, the liquid crystal molecules deflect under the action of the electric field. Since the liquid crystal molecules have different deflection degrees due to electric fields of different intensities, the sub-pixels have different transmittance, so that the sub-pixels achieve brightness at different gray scales, thereby achieving picture display. Of course, the display panel in the embodiment of the present disclosure may be an OLED display panel, which is not limited here.


The gray scale is that brightness change between the darkest and the brightest is divided into a plurality of parts to facilitate screen brightness control. For example, displayed images are composed of red, green and blue, each color may present different brightness levels, and red, green and blue of different brightness levels may be combined to form different colors. For example, the gray scale bits of the liquid crystal display panel is 6 bits, the three colors, red, green and blue, each have 64 (i.e. 26) gray scales, and values of these 64 gray scales are 0-63 respectively. The gray scale bits of the liquid crystal display panel is 8 bits, the three colors, red, green and blue, each have 256 (i.e. 28) gray scales, and values of these 256 gray scales are 0-255 respectively. The gray scale bits of the liquid crystal display panel is 10 bits, the three colors, red, green and blue, each have 1024 (i.e. 210) gray scales, and values of these 1024 gray scales are 0-1023 respectively. The gray scale bits of the liquid crystal display panel is 12 bits, the three colors, red. green and blue, each have 4096 (i.e. 212) gray scales, and values of these 4096 gray scales are 0-4095 respectively.


Taking one sub-pixel as an example, Vcom represents the voltage on the common electrode. When the data voltage input to the pixel electrode of the sub-pixel is greater than the voltage Vcom on the common electrode, the liquid crystal molecules at the sub-pixel may have a positive polarity, and the polarity corresponding to the data voltage in the sub-pixel is the positive polarity. When the data voltage input to the pixel electrode of the sub-pixel is less than the voltage Vcom on the common electrode, the liquid crystal molecules at the sub-pixel may have a negative polarity, and the polarity corresponding to the data voltage in the sub-pixel is the negative polarity. For example, the voltage on the common electrode may be 8.3 V, and if a data voltage of 8.8 V to 16 V is input to the pixel electrode of the sub-pixel SPX, the liquid crystal molecules at the sub-pixel SPX may have a positive polarity, and the data voltage of 8.8 V to 16 V is the data voltage corresponding to the positive polarity. If a data voltage of 0.6 V to 7.8 V is input to the pixel electrode of the sub-pixel SPX, the liquid crystal molecules at the sub-pixel SPX may have a negative polarity, and the data voltage of 0.6 V to 7.8 V is the data voltage corresponding to the negative polarity. Exemplarily, taking the 0-255 gray scale of 8 bits as an example, if the data voltage of 16 V is input to the pixel electrode of the sub-pixel SPX, the sub-pixel SPX may adopt the data voltage of the positive polarity to achieve the brightness with the maximum gray scale value (i.e. the gray scale value of 255). If the data voltage of 0.6 V is input to the pixel electrode of the sub-pixel SPX, the sub-pixel SPX may adopt the data voltage of the negative polarity to achieve the brightness with the maximum gray scale value (i.e. the gray scale value of 255). It should be noted that, the data voltage with the gray scale value 0 and the voltage on the common electrode may have a voltage difference, for example, the voltage on the common electrode is 8.3 V, the data voltage of the positive polarity corresponding to the gray scale value 0 may be 8.8 V. and the data voltage of the negative polarity corresponding to the gray scale value 0 may be 7.8 V. In this way, by controlling the polarity corresponding to the sub-pixels, the display panel may achieve a frame inversion manner, a column inversion manner, a row inversion manner, a point inversion manner and the like.


Of course, the data voltage with the gray scale value 0 and the voltage on the common electrode may also be the same. In practical applications, it may be determined according to requirements of practical applications, which is not limited here.


In some embodiments of the present disclosure, the display panel may further include a plurality of clock signal lines, and the plurality of clock signal lines are coupled with the gate driving circuit. In this way, a corresponding clock signal may be input to the gate driving circuit through the clock signal lines so as to load a signal to the gate lines. Exemplarily, as shown in FIG. 3, the display panel may further include 12 clock signal lines CK1-CK12, and the 12 clock signal lines CK1-CK12 are coupled with the gate driving circuit 120. Exemplarily, if the display panel adopts the design of a single gate driving circuit, the gate driving circuit may be coupled with the 12 clock signal lines CK1-CK12. If the display panel adopts the design of double gate driving circuits, each gate driving circuit may be coupled with the 12 clock signal lines CK1-CK12. It should be noted that FIG. 3 only makes illustration by taking an example of the 12 clock signal lines, and in practical applications, the specific quantity of the clock signal lines may be determined according to the requirements of the practical applications, which is not limited here. for example, the clock signal lines may have other quantities which is an integral multiple of 2, such as, 2, 4, 6, 8 and 10 clock signal lines and so on.


In some embodiments of the present disclosure, the original display data of the current display frame may be obtained, and when it is determined to adopt a second driving mode, second gate scanning signals may be loaded to the gate lines in the display panel, and a data voltage is loaded to the data lines directly according to the original display data to charge each sub-pixel in the display panel with the data voltage. Starting time points of effective pulses of the second gate scanning signals loaded to every two adjacent gate lines have the same difference. Exemplarily. the controller 400 may input a plurality of different second clock signals to the gate driving circuit in the display panel through the clock signal lines so as to load effective pulses in the second clock signals as effective pulses of the second gate scanning signals to the gate lines, so that the gate lines in the display panel may be driven row by row so as to turn on the transistors in the sub-pixels row by row. The controller 400 may obtain the original display data of the picture to be displayed in the current display frame (the original display data includes digital signal forms of the data voltages, with the corresponding gray scale values, corresponding to the sub-pixels one to one. In this way, the gray scale value corresponding to each sub-pixel may be determined according to the display data of the sub-pixel. In this way, a target data voltage corresponding to each sub-pixel may be obtained according to the determined gray scale value.) and send the original display data to the source driving circuit 120, so that the source driving circuit 120 loads the data voltage to the data lines in the display panel according to the received original display data, and thus the sub-pixels are charged, and are charged with the corresponding target data voltages to achieve the picture display function.


In some embodiments of the present disclosure, the controller 400 may include a timing controller 200 and a system controller 300. The system controller 300 may obtain the original display data of the picture to be displayed in the current display frame (the original display data includes the digital signal forms of the data voltages, which are provided with the gray scale values corresponding to the data voltages, corresponding to the sub-pixels one to one), and send. when it is determined to adopt the second driving mode, the original display data (that is, the original display data includes the digital signal forms of the data voltages, which are provided with the gray scale values corresponding to the data voltages, corresponding to the sub-pixels one to one) to the timing controller 200. The timing controller 200 may input the plurality of different second clock signals to the gate driving circuit in the display panel through the clock signal lines so as to load the effective pulses in the second clock signals as the effective pulses of the second gate scanning signals to the gate lines, so that the gate lines in the display panel may be driven row by row so as to turn on the transistors in the sub-pixels row by row. The timing controller 200 sends the original display data to the source driving circuit 120, so that the source driving circuit 120 loads the data voltage to the data lines in the display panel according to the received original display data, and thus the sub-pixels are charged, and are charged with the corresponding target data voltages to achieve the picture display function.


In some embodiments of the present disclosure, in the second driving mode, a signal sequence diagram corresponding to the gate driving circuit shown in FIG. 3 is as shown in FIG. 4. ck1_2 represents a second clock signal input to the clock signal line CK1, ck2_2 represents a second clock signal input to the clock signal line CK2, ck3_2 represents a second clock signal input to the clock signal line CK3, ck4_2 represents a second clock signal input to the clock signal line CK4, ck5_2 represents a second clock signal input to the clock signal line CK5, ck6_2 represents a second clock signal input to the clock signal line CK6, ck7_2 represents a second clock signal input to the clock signal line CK7, ck8_2 represents a second clock signal input to the clock signal line CK8, ck9_2 represents a second clock signal input to the clock signal line CK9, ck10_2 represents a second clock signal input to the clock signal line CK10, ck11_2 represents a second clock signal input to the clock signal line CK11, and ck12_2 represents a second clock signal input to the clock signal line CK12.


A signal ga1_2 represents the second gate scanning signal output to the gate line GA1 by the gate driving circuit 110, a signal ga2_2 represents the second gate scanning signal output to the gate line GA2 by the gate driving circuit 110, . . . , a signal ga10_2 represents the second gate scanning signal output to the gate line GA10 by the gate driving circuit 110, a signal ga11_2 represents the second gate scanning signal output to the gate line GA11 by the gate driving circuit 110, and a signal ga12_2 represents the second gate scanning signal output to the gate line GA12 by the gate driving circuit 110. Taking an example that a pulse corresponding to a high level is the effective pulse of each second gate scanning signal, a difference value between the starting time points of the effective pulses of the second gate scanning signals ga1_2 and ga2_2 is the same as a difference value between the starting time points of the effective pulses of the second gate scanning signals ga2_2 and ga3_2. The difference value between the starting time points of the effective pulses of the second gate scanning signals ga2_2 and ga3_2 is the same as a difference value between the starting time points of the effective pulses of the second gate scanning signals ga3_2 and ga4_2. A difference value between the starting time points of the effective pulses of the second gate scanning signals ga4_2 and ga5_2 is the same as a difference value between the starting time points of the effective pulses of the second gate scanning signals ga5_2 and ga6_2. The remaining is analogized and will not be repeated here.


The gate driving circuit includes a plurality of shifting register circuits; each of the shifting register circuits has clock signal output terminals; and the clock signal output terminals are coupled with the clock signal lines to receive the second clock signals. Exemplarily, the gate driving circuit 110 outputs the first high level of the second clock signal ck1_2 to the gate line GA1 to generate a high level in the signal ga1_2. The gate driving circuit 110 outputs the first high level of the second clock signal ck2_2 to the gate line GA2 to generate a high level in the signal ga2_2. . . . The gate driving circuit 110 outputs the first high level of the second clock signal ck10_2 to the gate line GA10 to generate a high level in the signal ga10_2. The gate driving circuit 110 outputs the first high level of the second clock signal ck11_2 to the gate line GA11 to generate a high level in the signal ga11_2. The gate driving circuit 110 outputs the first high level of the second clock signal ck12_2 to the gate line GA12 to generate a high level in the signal ga12_2. That is, a pulse corresponding to the high level of each second clock signal may be an effective pulse thereof, and a pulse corresponding to a low level may be an ineffective pulse thereof. Of course, when a shifting register outputs the low level of the second clock signal to generate a low-level signal, in the signals, for controlling the transistor to be turned on, the pulse corresponding to the low level of the second clock signal may be used as the effective pulse thereof, and the pulse corresponding to the high level may be used as the ineffective pulse thereof.

In some embodiments of the present disclosure, the original display data of the current display frame may be obtained, and when it is determined to adopt the first driving mode, a data voltage may be loaded to the data lines in the display panel according to the original display data corresponding to the sub-pixels in odd rows at the present display frame to charge each sub-pixel in the display panel with the data voltage. The same data voltage is input to the same column of sub-pixels in two adjacent rows. For example, taking the sub-pixels coupled with the data line DA2 as an example, as shown in FIG. 7, the data voltage D1 represents the target data voltage corresponding to the red sub-pixel R12, the data voltage D2 represents the target data voltage corresponding to the red sub-pixel R11, the data voltage D5 represents the target data voltage corresponding to the red sub-pixel R32, and the data voltage D6 represents the target data voltage corresponding to the red sub-pixel R31.

Exemplarily, the obtained original display data may include digital signal forms of data voltages, which are provided with gray scale values corresponding to the data voltages, corresponding to sub-pixels one to one. In this way, the gray scale value corresponding to each sub-pixel may be determined according to display data of the sub-pixel. In this way, a target data voltage corresponding to each sub-pixel may be obtained according to the determined gray scale value.

    • S200, when it is determined to adopt a first driving mode, first gate scanning signals are loaded to gate lines in the display panel, and a data voltage is loaded to data lines in the display panel according to target display data obtained by removing a part of data from the original display data, so as to charge each sub-pixel in the display panel with the data voltage.

Exemplarily, in combination with FIG. 11, a signal ga1_1 represents the first gate scanning signal loaded to the gate line GA1, a signal ga2_1 represents the first gate scanning signal loaded to the gate line GA2, a signal ga3_1 represents the first gate scanning signal loaded to the gate line GA3, a signal ga4_1 represents the first gate scanning signal loaded to the gate line GA4, a signal ga5_1 represents the first gate scanning signal loaded to the gate line GA5, a signal ga6_1 represents the first gate scanning signal loaded to the gate line GA6, a signal ga7_1 represents the first gate scanning signal loaded to the gate line GA7, and a signal ga8_1 represents the first gate scanning signal loaded to the gate line GA8. A high level is an effective pulse of the first gate scanning signal. Exemplarily, for the gate line GA2, the high level of the signal ga2_1 has a first overlapping duration t11 with the high level of the signal ga1_1, the high level of the signal ga2_1 has a second overlapping duration t21 with the high level of the signal ga3_1, and the first overlapping duration t11 and the second overlapping duration t21 corresponding to the gate line GA2 are different. For the gate line GA3, the high level of the signal ga3_1 has a first overlapping duration t12 with the high level of the signal ga2_1, the high level of the signal ga3_1 has a second overlapping duration t22 with the high level of the signal ga4_1, and the first overlapping duration t12 and the second overlapping duration t22 corresponding to the gate line GA3 are different.

For the gate line GA5, the high level of the signal ga5_1 has a first overlapping duration t14 with the high level of the signal ga4_1, the high level of the signal ga5_1 has a second overlapping duration t24 with the high level of the signal ga6_1, and the first overlapping duration t14 and the second overlapping duration t24 corresponding to the gate line GA5 are different. The remaining is in the same way. which is not repeated here.


In the driving method for the display panel provided by the embodiment of the present disclosure, when it is determined to adopt the first driving mode, target display data may be obtained by removing a part of data from the original display data, and the data voltage is loaded to the data lines in the display panel according to the target display data, so as to charge each sub-pixel in the display panel with the data voltage. In this way, a refresh frequency may be increased. the display smoothness is improved, and especially for a product with a high resolution, this driving mode may increase the charging rate of the display panel. By making the first overlapping duration and the second overlapping duration different, dislocation generated by the data voltage may be lowered, and the display effect is improved.

The system controller may obtain the original display data of the current display frame; and send, when it is determined to adopt the first driving mode, the target display data obtained by removing a part of data from the original display data to the timing controller. The timing controller may send the received target display data to a source driving circuit. The source driving circuit may load the data voltage to the data lines in the display panel according to the received target display data. In this way, the transmission amount of the display data may be reduced, the power consumption is lowered, and the transmission rate is increased.
