Abstract
Description
Technical Field
[0001] This application belongs to the field of display technology, and in particular relates to a GOA driving unit, a GOA driving circuit and a display device. Background Technology
[0002] Integrating gate driver on array (GOA) circuitry onto a glass substrate involves integrating the gate driver circuitry of the display panel onto the glass substrate, forming a scanning drive for the display panel. Compared to traditional gate chip-based driving technologies, GOA driving technology can significantly reduce manufacturing costs and reduce the left and right bezels of the display panel. A GOA driving circuit typically includes cascaded multi-stage GOA driving units. Each stage of the GOA driving unit drives one row of pixel units on the display panel. By cascading multiple stages of GOA driving units, line-by-line scanning of the display panel can be achieved.
[0003] In existing GOA driver units, the output of the inverting module is entirely controlled by the pull-up control node. When the potential of the pull-up control node changes from low to high, the inverting module begins to convert its output pull-down control signal from high to low. However, if the pull-down control signal changes slowly, the transistor it controls may not turn off in time, continuously pulling the potential of the pull-up control node low. This makes it difficult to pull the pull-up control node high, preventing the GOA driver unit from completing its driving operation correctly and reducing its operational stability.

[0036] This application first provides a GOA driving circuit, which may include cascaded multi-level GOA driving units. Each level of GOA driving unit can be used to drive a row of pixels on the display panel. The cascading of multiple levels of GOA driving units enables line-by-line scanning of the display panel.
[0037] This application also provides a GOA driving unit. Please refer to [link / reference]. Figure 1 This is a schematic diagram of the structure of a GOA driving unit provided in an embodiment of this application. Figure 1 As shown, in one optional implementation, the GOA driver unit may include a pull-up control module 10, a pull-up module 20, a pull-down module 30, an inverting module 40, a pull-down sustaining module 50, and a reset module 60. Wherein:
[0038] The pull-up control module 10 can be connected to the pull-up control node Qn. The pull-up control module 10 can be used to receive the first input signal G(nk) and output a high-level pull-up control signal to the pull-up control node Qn according to the high-level first input signal G(nk).
[0039] Pull-up module 20 can be connected to pull-up control node Qn. Pull-up module 20 can be used to receive scan clock signal CLK, and output gate drive signal G(n) from output node Rn according to pull-up control signal and scan clock signal. For example, pull-up control module 20 can output high-level gate drive signal G(n) from output node Rn according to high-level pull-up control signal and high-level scan clock signal. Gate drive signal G(n) can be used to drive a row of pixel units corresponding to the current GOA driving unit, or it can be used as an input signal for other GOA driving units.
[0040] The pull-down module 30 can be connected to the pull-up control node Qn. The pull-down module 30 can be used to receive a second input signal G(n+j) and, based on the second input signal G(n+j), pull the pull-up control node Qn down to a low level VSS. For example, the pull-down module 30 can pull the pull-up control node Qn down to a low level VSS based on the high-level second input signal G(n+j).
[0041] The inverting module 40 can be connected to the pull-up control node Qn and the pull-down control node Kn. The inverting module 40 can be used to receive the first input signal G(nk) and the preset high-level signal VGH, invert the pull-up control signal according to the high-level first input signal G(nk) and the preset high-level signal VGH, and output the corresponding inverted signal to the pull-down control node Kn.
[0042] The pull-down sustaining module 50 can be connected to the pull-up control node Qn, the pull-down control node Kn, and the output node Rn. The pull-down sustaining module 50 can be used to maintain the pull-up control node Qn and the output node Rn at a low level VSS based on an inverted signal. For example, the pull-down sustaining module 50 can maintain the pull-up control node Qn and the output node Rn at a low level VSS based on an inverted high signal.
[0043] The reset module 60 can be connected to the pull-up control node Qn and the output node Rn. The reset module 60 can be used to pull down the pull-up control node Qn and the output node Rn according to a reset signal. For example, the reset module 60 can pull down the pull-up control node Qn and the output node Rn to a low level VSS according to a high-level reset signal.
[0044] Wherein, the first input signal G(nk) can be the gate drive signal output by the k-th stage GOA drive unit, and the second input signal G(n+j) can be the gate drive signal output by the j-th stage GOA drive unit, where k and j are positive integers. k and j can be determined according to the number of cycles of the scan clock signal connected to the pull-up module 20.
[0045] Figure 2 This is a waveform diagram of various signals received by a GOA driving unit during operation, provided in an embodiment of this application. Figure 3 This diagram illustrates the voltage level changes of the pull-up and pull-down control nodes in the GOA driver unit. Figure 3 (a) in the diagram is a schematic diagram of the level changes of the pull-up control node and pull-down control node in the existing GOA driver unit. Figure 3 (b) is a schematic diagram of the level changes of the pull-up control node and the pull-down control node in a GOA driving unit provided in an embodiment of this application.
[0046] The following combination Figure 2and Figure 3 The working principle of the GOA driving unit will be explained.
[0047] like Figure 2 As shown, during stage A to B, the first input signal G(nk) is high, while the scan clock signal CLK and the second input signal G(n+j) are low. Based on this, as... Figure 3 As shown in (a) of this embodiment, the inverting module 40 can quickly pull down the pull-down control Kn to a low level according to the high-level first input signal G(nk), thereby enabling the pull-up control module 10 to quickly pull up the pull-up control node Qn to a first high level according to the high-level first input signal G(nk). Figure 3 As can be seen, by synchronously inputting the high-level first input signal G(nk) to the pull-up control module 10 and the inverting module 40, the time for the pull-up control node Qn to transition from low to high level can be significantly shortened in this embodiment. Furthermore, since the pull-up control node Qn is pulled up to the first high level and the scan clock signal CLK is low, the pull-up module 20 outputs a low-level signal to the output node Rn, making the output node Rn low. Because the second input signal G(n+j) is low, the pull-down module 30 is turned off.
[0048] During stages B to C, the scan clock signal CLK is high, and both the first input signal G(nk) and the second input signal G(n+j) are low. At this time, both the pull-up control module 10 and the pull-down module 30 are off. Due to the presence of the bootstrap capacitor in the pull-up module 20, the pull-up control node Qn is maintained at a second high level. This second high level is greater than the first high level. The inverting module 40 inverts the high-level pull-up control signal according to the preset high-level signal VGH and outputs a low-level inverted signal to the pull-down control node Kn, making Kn low. Since both the scan clock signal CLK and the pull-up control node Qn are high, the pull-up control module 20 outputs a high-level gate drive signal G(n) based on the high-level scan clock signal CLK and the pull-up control signal, making the output node Rn high.
[0049] During stages C to D, the scan clock signal CLK, the first input signal G(nk), and the second input signal G(n+j) are all at low levels. At this time, both the pull-up control module 10 and the pull-down module 30 are off, and the pull-up control node Qn remains at the first high level. The inverting module 40 inverts the high-level pull-up control signal according to the preset high-level signal VGH and outputs a low-level inverted signal to the pull-down control node Kn, making the pull-down control node Kn low. Since the pull-up control node Qn is high and the scan clock signal CLK is low, the pull-up control module 20 outputs a low-level signal to the output node Rn, making the output node Rn low.
[0050] During stages D to E, the second input signal G(n+j) is high, while the first input signal G(nk), the scan clock signal CLK, and the reset signal Reset are all low. At this time, the pull-down module 30 pulls the pull-up control node Qn low. Since both the pull-up control node Qn and the scan clock signal CLK are low, the pull-up module 20 outputs a low-level signal to the input node Rn, pulling the gate drive signal G(n) low. The inverting module 40 inverts the low-level pull-up control signal according to the preset high-level signal VGH and outputs a high-level inverted signal to the pull-down control node Kn, making the pull-down control node Kn high.
[0051] During stages F to G, the reset signal Reset is high, while the first input signal G(nk), the second input signal G(n+j), and the scan clock signal CLK are all low. At this time, the reset module 60 pulls the pull-up control node Qn down to low and pulls the output node Rn down to low, keeping the gate drive signal G(n) low.
[0052] As can be seen from the above, by synchronously inputting a high-level first input signal to the inverting module and the pull-up control module, the inverting module can quickly pull the potential of the pull-down control node down while the pull-up control module starts to pull the pull-up control node to a high level. This effectively reduces the potential pull phenomenon between the pull-up control node and the pull-down control node, allowing the pull-up control node to be pulled up to a high level more quickly and reliably, thereby improving the working stability of the GOA driver unit.
[0053] Please see Figure 4 This is a schematic diagram of the circuit structure of a GOA driving unit provided in an embodiment of this application. For ease of explanation, only the parts related to the embodiment of this application are shown, and are described in detail below:

[0055] The pull-up module 20 may include a second transistor T2 and a first capacitor C1. The gate of the second transistor T2 may be connected to the pull-up control node Qn along with the first terminal of the first capacitor C1. The source of the second transistor T2 may be used to connect to the scan clock signal CLK, and the drain of the second transistor T2 may be connected to the output node Rn along with the second terminal of the first capacitor C1. For example, the first capacitor C1 may be a bootstrap capacitor.
[0056] The pull-down module 30 may include a third transistor T3. The gate of the third transistor T3 can be used to connect to the second input signal G(n+j), the source of the third transistor T3 can be connected to the pull-up control node Qn, and the drain of the third transistor T3 can be connected to a low-level terminal. The low-level terminal is used to provide a low level VSS.
[0057] The inverting module 40 may include a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, and a seventh transistor T7. The gate and source of the fourth transistor T4 and the source of the sixth transistor T6 can be connected to a preset high-level signal VGH. The drain of the fourth transistor T4 and the source of the fifth transistor T5 can be connected to the gate of the sixth transistor T6. The gate of the fifth transistor T5 can be connected to the pull-up control node Qn. The gate of the seventh transistor T7 can be connected to the first input signal G(nk). The drains of the fifth transistor T5 and the seventh transistor T7 can be connected to a low-level terminal. The drain of the sixth transistor T6 and the source of the seventh transistor T7 can be connected to the pull-down control node Kn.
[0058] The pull-down sustaining module 50 may include an eighth transistor T8 and a ninth transistor T9. The gate of the eighth transistor T8 and the gate of the ninth transistor T9 may be connected to the pull-down control node Kn, the source of the eighth transistor T8 may be connected to the pull-up control node Qn, the source of the ninth transistor T9 may be connected to the output node Rn, and the drain of the eighth transistor T8 and the drain of the ninth transistor T9 may be connected to a low-level terminal.
[0059] The reset module 60 may include a tenth transistor T10 and an eleventh transistor T11. The source of the tenth transistor T10 may be connected to the pull-up control node Qn, and the source of the eleventh transistor T11 may be connected to the output node Rn. The gates of the tenth transistor T10 and the eleventh transistor T11 may be used to receive the reset signal Reset, and the drains of the tenth transistor T10 and the eleventh transistor T11 may be connected to a low-level terminal.
[0060] The following combination Figure 2 and Figure 3 The working principle of the GOA driving unit will be further explained.
[0061] During phase A to B, the first input signal G(nk) is high, while the scan clock signal CLK, the second input signal G(n+j), and the reset signal Reset are all low. At this time, the seventh transistor T7 in the inverter module 40 and the first transistor T1 in the pull-up control module 10 are synchronously turned on, thereby quickly pulling down the pull-down control node Kn to a low level, thus enabling the pull-up control node Qn to be pulled up to the first high level. According to... Figure 3 As can be seen, by synchronously inputting the high-level first input signal G(nk) to the pull-up control module 10 and the inverting module 40, the time for the pull-up control node Qn to transition from low to high level can be significantly shortened in this embodiment. Furthermore, since the pull-up control node Qn is pulled up to the first high level and the scan clock signal CLK is low, the second transistor T2 in the pull-up module 20 is turned on, and the pull-up module 20 outputs a low-level signal to the output node Rn, making the output node Rn low. Since the second input signal G(n+j) is low, the third transistor T3 in the pull-down module 30 is turned off, thereby turning off the pull-down module 30.
[0062] During stages B to C, the scan clock signal CLK is high, and both the first input signal G(nk) and the second input signal G(n+j) are low. At this time, the first transistor T1 in the pull-up control module 10 is off, thus turning off the pull-up control module 10. The third transistor T3 in the pull-down module 30 is off, thus turning off the pull-down module 30. Due to the presence of the bootstrap capacitor in the pull-up module 20, the pull-up control node Qn is maintained at a second high level, which is greater than the first high level. The fourth transistor T4, the fifth transistor T5, and the sixth transistor T6 in the inverter module 40 are on, and the seventh transistor T7 is off, enabling the inverter module 40 to output a low-level inverted signal to the pull-down control node Kn, making the pull-down control node Kn low. Since both the scan clock signal CLK and the pull-up control node Qn are high, the second transistor T2 in the pull-up control module 20 is on, outputting a high-level gate drive signal G(n), making the output node Rn high.
[0063] During stages C to D, the scan clock signal CLK, the first input signal G(nk), and the second input signal G(n+j) are all at low levels. Since the first input signal G(nk) is low, the first transistor T1 in the pull-up control module 10 is off, thus turning off the pull-up control module 10. The third transistor T3 in the pull-down module 30 is off, thus turning off the pull-down module 30, and the pull-up control node Qn remains at a high level. The fourth transistor T4, the fifth transistor T5, and the sixth transistor T6 in the inverter module 40 are on, and the seventh transistor T7 is off, enabling the inverter module 40 to output a low-level inverted signal to the pull-down control node Kn, making the pull-down control node Kn low. Since the pull-up control node Qn is high and the scan clock signal CLK is low, the second transistor T2 in the pull-up module 20 is on, outputting a low-level signal to the output node Rn, making the output node Rn low.
[0064] During stages D to E, the second input signal G(n+j) is high, while the first input signal G(nk), the scan clock signal CLK, and the reset signal Reset are all low. At this time, the third transistor in pull-down module 30 is on, pulling the pull-up control node Qn low. Since both the pull-up control node Qn and the scan clock signal CLK are low, the second transistor T2 in pull-up module 20 is off, and pull-up module 20 outputs a low-level signal to input node Rn, pulling the gate drive signal G(n) low. The fourth transistor T4 and the sixth transistor T6 in inverter module 40 are on, while the fifth transistor T5 and the seventh transistor T7 are off, enabling inverter module 40 to output a high-level inverted signal to pull-down control node Kn, making pull-down control node Kn high.
[0065] During stages F to G, the reset signal Reset is high, while the first input signal G(nk), the second input signal G(n+j), and the scan clock signal CLK are all low. At this time, the tenth transistor T10 and the eleventh transistor T11 in the reset module 60 are both turned on, thereby pulling the pull-up control node Qn down to a low level and pulling the output node Rn down to a low level.
