Description

Technical Field

[0001] This invention relates to the field of display technology, and more particularly to a driving circuit, driving method, and display device. Background Technology

[0002] The application of OLED (Organic Light Emitting Diode) displays has gradually expanded from small and medium-sized watches, mobile phones, and tablets to PCs (Personal Computers) and monitors. These applications are characterized by high PPI (Pixels Per Inch) but high absolute resolution. Due to the diverse usage scenarios faced by PCs, the requirements for refresh rates vary greatly. For example, text reading or power-saving modes generally require refresh rates below 10Hz, while web browsing and video playback require 48Hz to 60Hz. Gaming and other scenarios require refresh rates of 120Hz to 144Hz or even above 240Hz. This necessitates good display performance across refresh rates ranging from a few Hz to 200Hz to 300Hz.

[0003] In related technologies, a pixel structure is employed that separates the threshold voltage compensation and data voltage writing operations. Because this structure separates data voltage writing and threshold voltage compensation, the threshold voltage compensation time can be set to be longer according to display needs (compensation effect, afterimage effect, etc.). The related driving circuit uses an alternating output of off and on voltages for convenient pulse width control. However, an additional bootstrap structure is required to pull the output voltage low or high. Therefore, the falling or rising edge width of the driving method provided by the driving circuit reaches the time of one line, which carries the risk of causing mura (display unevenness).

[0143] During the input phase, ROUT provides a first voltage signal. Under the control of the first clock signal provided by the first clock signal terminal CK1, the third node control circuit 13 controls the connection between the third node N3 and the first output control terminal ROUT. Under the control of the potential of the third node N3, the second output circuit 16 controls the connection between the first output clock signal terminal CKO1 and the drive output terminal AZOUT.

[0144] In the first output stage, the second output circuit 16, under the control of the potential of the third node N3, controls the connection between the first output clock signal terminal CKO1 and the drive output terminal AZOUT. The potential of the first output clock signal provided by the first output clock signal terminal CKO1 jumps from the second voltage to the first voltage, so that the potential of the drive signal provided by the drive output terminal AZOUT jumps from the second voltage to the first voltage.

[0145] In related technologies, data writing and threshold voltage compensation are performed by the same circuit structure. This results in the inability to fully compensate for the threshold voltage within a very short line time (high-frequency frames). Simultaneously, the non-uniformity of the driving transistor characteristics amplifies the impact on pixel data writing, leading to a significant degradation in display quality. Therefore, alternative threshold voltage compensation methods are needed to improve the accuracy of pixel data writing and the threshold voltage compensation time, thereby enhancing image quality. To address these issues, a pixel structure that separates threshold voltage compensation and data voltage writing is adopted. Because this pixel structure separates data voltage writing and threshold voltage compensation, the threshold voltage compensation time can be set to be longer according to display needs (compensation effect, image retention effect, etc.).

[0146] like Figure 5As shown, at least one embodiment of the pixel circuit may include an organic light-emitting diode O1, a first display control transistor M1, a second display control transistor M2, a third display control transistor M3, a fourth display control transistor M4, a fifth display control transistor M5, a sixth display control transistor M6, a seventh display control transistor M7, an eighth display control transistor M8, a ninth display control transistor M9, a first display control capacitor Cx1, and a second display control capacitor Cx2.

[0160] Figure 5 In at least one embodiment of the pixel circuit shown, threshold voltage compensation is controlled by AZOUT and data voltage writing is controlled by GOUT during operation.

[0161] exist Figure 5 In at least one embodiment of the pixel circuit shown, T2 can be a p-type transistor, and the low-voltage pulse time of the drive signal provided by the drive output terminal AZOUT needs to be adjustable. Traditional drive circuits use an alternating output of the turn-off voltage and the turn-on voltage Vgl because it is convenient to control the pulse width. However, since the voltage at the gate of the output transistor is also the turn-on voltage Vgl when the turn-on voltage Vgl is output, the limit of the output voltage is Vgl-Vth, where Vth is the threshold voltage of the output transistor. Therefore, it is impossible to reduce the output voltage to Vgl within one line time. An additional pull-down bootstrap structure is required to pull the output voltage down to Vgl. As a result, the falling edge width reaches the time of one line, which poses a risk of mura (display inhomogeneity).

[0162] Based on this, in this embodiment of the invention, the first output control terminal ROUT controls the potential of the third node, and then the second output circuit, under the control of the potential of the third node, controls the connection or disconnection between the first output clock signal terminal and the drive output terminal, thereby pulling down the potential of the drive signal provided by the drive output terminal AZOUT, reducing the fall time of the drive signal, and enabling the pulse width of the drive signal to be adjustable.
