Embodiment 1
[0034] This embodiment provides a gate driving device, including a shift register unit, one end of each row of gate lines is connected to one of the shift register units, the other end of the gate line is connected to an auxiliary drive circuit, and one of the rows is connected to the A gate line of an auxiliary driving circuit, the auxiliary driving circuit compensates the row gate line with a control signal through the control of other row gate lines connected thereto.
[0035] Wherein, the control signal is mainly used to charge the current row of gate lines at the time when the operating voltage is turned on, and at the same time to charge the current row of gate lines at the time when the operating voltage is turned off. Of course, in the intermediate time period, the control signal can also charge the current row of gate lines. The charge is maintained to reduce the signal delay at both ends of the gate line. The control signal can directly use the clock control signal of t...
Embodiment 2
[0038] This embodiment provides a gate driving device, such as figure 2 As shown, it includes: a substrate 1, a plurality of rows of gate lines 14 arranged on the substrate 1, a plurality of shift register units 13, and an auxiliary driving circuit 15, respectively transmitting a plurality of clock control signals CK1, CK2, CK3, CK4 The multiple clock control signal lines 2 (that is, this embodiment takes 2 groups of 4 lines as an example).
[0039] Each shift register unit 13 in this embodiment is directly fabricated on the substrate through an array process.
[0040] Such as figure 2 As shown, the input end of each shift register unit 13 is connected to the corresponding clock control signal line 2, while its output end is connected to one end of the corresponding gate line 14, and the other end of the gate line 14 is connected to the auxiliary drive circuit 15. .
[0041] Preferably, the other end of each row of gate line 14 is connected to the clock control signal 2 through tw...
Embodiment 3
[0055] This embodiment provides a display device, which includes:
[0056] The gate driving device in any one of the above embodiments.
[0057] Of course, the display device of this embodiment may also include other known components such as a color filter substrate, a power supply unit, and a backlight, which will not be described in detail here.
[0058] Since the display device of this embodiment has the above-mentioned gate drive device, its circuit is simple and the gate drive circuit occupies a small space. Therefore, the effective display area can be increased without changing the characteristics of the existing gate signal. , And provide the possibility to realize the narrow frame of the display device, making the display device more beautiful.
