[0057] Figure 4 Show Figure 1 A schematic block diagram of a driving circuit according to an embodiment. Figure 5 Show Figure 1 A schematic circuit diagram of a display unit in a display panel according to an embodiment. Figure 6 Show Figure 5 Schematic diagram of waveforms of various signals in the display unit of the embodiment. Please refer to Figures 4 to 6 The display panel 120 includes a plurality of first scan lines 501 , a plurality of second scan lines 502 , and a plurality of display units 122 . The display units 122 are coupled to the driving circuit 110 through the first scan lines 501 and the second scan lines 502 .

[0058] The display unit 122 is, for example, a pixel circuit on the display panel 120. The display unit 122 includes a plurality of transistor elements T1 to T8, a capacitor element C1, and a light emitting element 510, wherein the transistor element T1 serves as a driving element 520, and the transistor element T7 serves as a reset element 530. The light emitting element 510 is, for example, an organic light emitting diode. Specifically, the light emitting element 510 has a first end and a second end, which are respectively an anode and a cathode of the organic light emitting diode. The first end of the light emitting element 510 is coupled to the first end of the reset element 530, and the second end of the light emitting element 510 is coupled to the first voltage ELVSS. The reset element 530 has a first end, a second end, and a control end. The first end of the reset element 530 is coupled to the first end of the light emitting element 510, and the second end of the reset element 530 is coupled to the reset signal S1. The control end of the reset element 530 is coupled to the corresponding first scan line 501. When the reset element 530 is turned on by the scan signal pScan1, the reset signal S1 can reset the first end of the light emitting element 530. In addition, the connection relationship between other components and signals in the display unit 122 is as follows: Figure 5 shown.

[0059] On the other hand, the driving circuit 110 includes a control circuit 112, a voltage generating circuit 114 and a data output circuit 116. The control circuit 112 can be used to output scanning signals pScan1, pScan2, nScan1, nScan2 and a driving signal EM to corresponding transistor elements to control the conduction state of the corresponding transistor elements. In an embodiment, the scanning signal can be output by a gate on array (GOA) on the display panel 120 according to the control signal of the control circuit 112.

[0060] The voltage generating circuit 114 can be used to output reset signals S1, S2 and bias signals VB to reset corresponding circuit nodes or provide bias to corresponding circuit nodes. Therefore, the driving circuit 110 can be used to output the scan signal pScan1 and the reset signal S1 to the display panel 120. In an embodiment, the bias signal VB is, for example, a positive voltage. The voltage generating circuit 114 further outputs a first voltage ELVSS and a second voltage ELVDD to the display unit 122 as operating voltages, wherein the first voltage ELVSS is a system low voltage and the second voltage ELVDD is a system high voltage. In addition, the data output circuit 116 can be used to output a data voltage VD to write corresponding display data into the display unit 122 in the write frame F1.

[0061] exist Figure 4In the embodiment of the present invention, the control circuit 112 may be a processor with computing capabilities. Alternatively, the control circuit 112 may be designed by hardware description languages ​​(HDL) or any other digital circuit design method familiar to those skilled in the art, and may be a hardware circuit implemented by a field programmable gate array (FPGA), a complex programmable logic device (CPLD), or an application-specific integrated circuit (ASIC). In addition, regarding the hardware structure of the control circuit 112, the voltage generating circuit 114, and the data output circuit 116, sufficient teachings, suggestions, and implementation instructions may be obtained by referring to the common knowledge in the relevant art.

[0062] exist Figure 5 In the embodiment of the present invention, the number of transistors and capacitors is not limited to the present invention. That is to say, the signal compensation method proposed in the embodiment of the present invention is not limited to the application in Figure 5 in the circuit structure.

[0063] Please refer to Figure 6 , Figure 6 The operation sequence of the display unit 122 and the waveforms of various signals are shown. In the writing frame F1, the operation sequence of the display unit 122 can be roughly divided into steps S100 to S140.

[0064] In step S100, transistor elements T3, T7, and T8 are turned on, and transistor elements T2, T4, T5, and T6 are not turned on. The bias signal VB resets the first end S of the transistor element T1, and the reset signal S1 resets the first end A of the light-emitting element 510. Taking an organic light-emitting diode as an example, the reset signal S1 is used to reset the anode voltage of the organic light-emitting diode. In step S100, the scan signal pScan1 is at a low level in the reset interval Trst, which can be used to turn on the transistor element T7, so that the reset signal S1 can reset the first end A of the light-emitting element 510. The level of the scan signal pScan1 in the reset interval Trst is not intended to limit the present invention.

[0065] In step S110, transistor elements T3 and T4 are turned on, and transistor elements T2, T5, T6, T7, and T8 are turned off. The reset signal S2 resets the second terminal D and the control terminal G of the transistor element T1.

[0066] In step S120, transistor elements T1, T2, and T3 are turned on, and transistor elements T4, T5, T6, T7, and T8 are turned off. The data voltage VD can be written into the control terminal G of the transistor element T1.

[0067] In step S130 , transistor elements T7 and T8 are turned on, and transistor elements T2 , T3 , T4 , T5 , and T6 are turned off. The bias signal VB resets the first end S of the transistor element T1 again, and the reset signal S1 resets the first end A of the light emitting element 510 again.

[0068] In step S140, transistor elements T1, T5, and T6 are turned on, and transistor elements T2, T3, T4, T7, and T8 are turned off. The driving current of transistor elements T1, T5, and T6 can drive the light emitting element 510 to emit light.

[0069] exist Figure 6 In the embodiment of FIG. 1 , since the scan signal pScan1 may include a plurality of reset intervals Trst when driving the entire display panel 120, the reset interval Trst may turn on the transistor element T7. When the reset interval Trst of the scan signal pScan1 is transmitted in the non-display area of ​​the display panel 120, the display panel 220A may have the following Figure 3A The dark band 300 is shown. The non-display area here is, for example, a porch area or a blanking area of ​​the display panel 120.

[0070] Therefore, if the driving circuit 110 does not compensate the reset signal S1, for example, only provides a fixed low-level reset signal S1, then the voltage of the reset signal S1 will change with the change of the impedance of the first end A of the light-emitting element 510, thereby affecting the effect of the reset signal S1 on resetting the first end A of the light-emitting element 510.

[0071] Therefore, in the embodiment of the present invention, when the reset interval Trst of the scan signal pScan1 is transmitted in the non-display area of ​​the display panel 120, the driving circuit 110 compensates the reset signal S1 and outputs the compensated reset signal S1 to reset the first end A of the light emitting element 510. That is, taking an organic light emitting diode as an example, the signal compensation method of the embodiment of the present invention can dynamically compensate the anode voltage of the organic light emitting diode.

[0072] Figure 7 FIG. 2 is a schematic diagram showing a waveform of a reset signal according to an embodiment of the present invention. Figure 7 ,exist Figure 7 In the embodiment, the reset signal S1′ is an uncompensated reset signal, and the reset signal S1 is a reset signal compensated by the signal compensation method of the embodiment of the present invention.

[0073] The uncompensated reset signal S1' is, for example, a fixed low-level voltage signal. The compensated reset signal S1 includes, for example, a plurality of compensation intervals Tcomp. The driving circuit 110 can determine the position and width of the compensation interval Tcomp according to the position and width of the reset interval Trst of the scan signal pScan1. In the present embodiment, the compensated reset signal S1 is a step signal 700 in the compensation interval Tcomp. The waveform of the step signal 700 is only used for illustration and is not intended to limit the present invention.

[0074] The following describes how the driving circuit 110 compensates the reset signal S1 to determine the position and width of the compensation interval Tcomp and the waveform of the step signal 700 .

[0075] Figure 8 FIG. 2 is a schematic diagram showing a waveform for driving a display panel according to an embodiment of the present invention. Figure 1 , Figure 2 and Figure 8 , Figure 8 The embodiment shown is that when the reset interval Trst of the scan signals pScan1_m, pScan1_(m+1), pScan1_(m+2), pScan1_(m+3), pScan1_(m+4) enters the non-display area PA of the display panel 120, the driving circuit 110 compensates for the reset signal S1.

[0076] Specifically, in Figure 8 , the scanning signal pScan1_0 is a scanning signal output from the driving circuit 110 to the display panel 120. The scanning signal pScan1_0 includes a plurality of reset intervals Trst. The scanning signals pScan1_m, pScan1_(m+1), pScan1_(m+2), pScan1_(m+3), and pScan1_(m+4) (hereinafter simply labeled as pScan1) are scanning signals transmitted on five different adjacent scanning lines 501 on the display panel 120, respectively, wherein a portion of each scanning signal pScan1 corresponds to the display area DA of the display panel 120, and another portion corresponds to the non-display area PA of the display panel 120. Each scanning signal pScan1 also includes a plurality of reset intervals Trst.

[0077] On the other hand, the reset signal S1 is a compensated reset signal. The compensated reset signal S1 includes a plurality of compensation intervals Tcomp. The compensation interval Tcomp includes a high level interval Tpa and the width of the step signals 800A and 800B.

[0078] Figure 8The waveform of the scanning signal pScan1 transmitted on different scanning lines 501 is shown. As the scanning signal pScan1 is transmitted to the front end portion close to the non-display area PA, the reset interval Trst of the scanning signal pScan1 begins to enter the non-display area PA of the display panel 120, as shown in the dashed frame portion 801. At this time, in the display area DA, corresponding to the position of the reset interval Trst of the scanning signal pScan1, as shown in the dashed frame portions 802 and 803, the driving circuit 110 will compensate the reset signal S1, for example, gradually increase the voltage level of the reset signal S1 so that it has a waveform of the step signal 800A in the compensation interval Tcomp. Then, the reset signal S1 will be maintained at a high level for an interval Tpa, and the width of this interval Tpa is substantially equal to the width of the non-display area PA. In other words, the driving circuit 110 can determine the width of the interval Tpa according to the width of the non-display area PA of the display panel 120, thereby determining the width of the compensation interval Tcomp. Afterwards, the driving circuit 110 also uses a step adjustment method to gradually adjust the voltage level of the reset signal S1 back to a low level, as shown by the waveform of the step signal 800B.

[0079] Therefore, the driving circuit 110 compensates the reset signal S1 according to the position of the reset interval Trst. For example, the driving circuit 110 determines the position of the compensation interval Tcomp according to the position of the reset interval Trst, and makes the position of the compensation interval Tcomp correspond to the position of the reset interval Trst. In this way, the driving circuit 110 can prevent the display panel 120 from having a dark band by resetting the first end A of the light emitting element 510 using the compensated reset signal S1.

[0080] In an embodiment, the width of the reset interval Trst of the scan signal pScan1 corresponds to the number of signal lines (e.g., data lines) of the display panel 120. For example, the width of each reset interval Trst of the scan signal pScan1 corresponds to four signal lines. Therefore, when the reset interval Trst of the scan signal pScan1 begins to enter the non-display area PA of the display panel 120, the drive circuit 110 gradually increases the voltage level of the reset signal S1. Therefore, the number of steps of the step signal 800A is four, which is equal to the number of signal lines corresponding to the width of the reset interval Trst. In other words, the drive circuit 110 can determine the width of the step signals 800A and 800B according to the width of the reset interval Trst, thereby determining the width of the compensation interval Tcomp.

[0081] Fig. 9 FIG. 2 is a waveform diagram showing another embodiment of the present invention for driving a display panel. Figure 1 , Figure 2 and Fig. 9 , Fig. 9The embodiment shown is that when the reset interval Trst of the scan signals pScan1_m, pScan1_(m+1), pScan1_(m+2), pScan1_(m+3), pScan1_(m+4) leaves the non-display area PA of the display panel 120, the driving circuit 110 compensates for the reset signal S1.

[0082] Specifically, Fig. 9 The waveform of the scanning signal pScan1 transmitted on different scanning lines 501 is shown. As the scanning signal pScan1 is transmitted to the rear end portion close to the non-display area PA, the reset interval Trst of the scanning signal pScan1 is ready to leave the non-display area PA of the display panel 120, as shown in the dashed frame portion 901. At this time, in the display area DA, corresponding to the position of the reset interval Trst of the scanning signal pScan1, as shown in the dashed frame portions 902 and 903, the driving circuit 110 will compensate the reset signal S1, for example, gradually increase the voltage level of the reset signal S1 so that it has the waveform of the step signal 900A in the compensation interval Tcomp. Then, the reset signal S1 will be maintained at a high level for an interval Tpa, and the width of this interval Tpa is substantially equal to the width of the non-display area PA. Afterwards, the driving circuit 110 also uses the step adjustment method to gradually adjust the voltage level of the reset signal S1 back to a low level, as shown in the waveform of the step signal 900B.

[0083] Therefore, the driving circuit 110 can compensate the reset signal S1 according to the position of the reset interval Trst. For example, the driving circuit 110 determines the position of the compensation interval Tcomp according to the position of the reset interval Trst, and makes the position of the compensation interval Tcomp correspond to the position of the reset interval Trst. In this way, the driving circuit 110 can prevent the display panel 120 from having a dark band by resetting the first end A of the light emitting element 510 using the compensated reset signal S1.

[0084] exist Figure 8 and Fig. 9 In the embodiment of the present invention, the number of steps of the step signals 800A, 800B, 900A, 900B and the number of signal lines corresponding to the width of the reset interval Trst are only used for illustration and are not intended to limit the present invention.

[0085] exist Figure 8 and Fig. 9In the embodiment, the driving circuit 110 determines the position, width and waveform of the step signal of the compensation interval Tcomp according to the scan signal pScan1 transmitted on the display panel 120, but the present invention is not limited thereto. In the embodiment, since the scan signal pScan1 can be generated by the scan signal pScan1_0, the driving circuit 110 can also determine the position, width and waveform of the step signal of the compensation interval Tcomp according to the scan signal pScan1_0 outputted by itself.

[0086] Fig.10 A circuit diagram of a display unit in a display panel according to another embodiment of the present invention is shown. Fig.10 The display unit 1022 is another embodiment of the pixel circuit on the display panel 120. In this embodiment, the display unit 122 includes seven transistor elements T1 to T7, a capacitor element C1 and a light emitting element 1010. For the operation of the display unit 1022, please refer to Figure 5 The embodiments provide sufficient guidance, suggestions and implementation instructions. Figure 5 The number of transistors and capacitors does not limit the present invention. The signal compensation method proposed in the embodiment of the present invention can also be applied to Fig.10 in the circuit structure.

[0087] In summary, in the embodiment of the present invention, the driving circuit can determine the position, width and signal waveform of the compensation interval of the reset signal according to the scanning signal to dynamically compensate the terminal voltage of the light-emitting element. In this way, dark bands can be avoided on the display panel, thereby improving the display quality.
