Title:
DRIVING CIRCUIT, DISPLAY DRIVING CHIP, DISPLAY DEVICE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/012453
Kind Code:
A1
Abstract:
The present invention relates to a driving circuit, a display driving chip, a display device, and an electronic device. The driving circuit comprises a first-stage circuit, a second-stage circuit, and an auxiliary circuit; the first-stage circuit is used for receiving a first input signal and a second input signal and amplifying same to obtain a first output signal and a second output signal and output same to the second-stage circuit; the second-stage circuit is used for outputting a third output signal according to the first output signal and the second output signal so as to drive a load; the second-stage circuit is also connected to the first-stage circuit by means of a Miller capacitor; and the auxiliary circuit is connected to the first-stage circuit and the second-stage circuit and is used for reducing the output impedance of the first-stage circuit. The driving circuit, as a driving circuit for Miller compensation, can satisfy the requirements for connection to any load capacitor and smooth transient response.
