Abstract: A source driver module, a display device and a method for driving a display panel are provided. The method for driving a display panel is applicable to the source driver module, which includes a source driver circuit, a first switch coupled between the source driver circuit and a first end of a first data line, and a second switch coupled between the source driver circuit and a second end of the first data line. The method for driving the display panel includes: when the display panel displays a first image, the source driver circuit outputs a first voltage signal to the first end of the first data line through the first switch, and when the display panel displays a second image after displaying the first image, the source driver circuit outputs a second voltage signal to the second end of the first data line through the second switch.

Abstract: A display apparatus including a voltage buffer, a display panel and a pixel loading compensation circuit is disclosed. The voltage buffer is used to receive a ramp voltage and output an output current. The display panel includes pixel switches and pixel capacitors. The pixel switches are arranged in parallel and coupled to the voltage buffer. The pixel capacitors are coupled between the pixel switches and ground. The pixel loading compensation circuit includes compensation switches and compensation current sources. The compensation switches corresponding to the pixel switches are arranged in parallel and coupled to the voltage buffer. The compensation current sources are coupled between the compensation switches and ground. The operation of the compensation switches is opposite to the operation of the corresponding pixel switches.

Abstract: A display apparatus and a voltage calibration method are disclosed. The display apparatus includes a ramp voltage generator, a ramp counter and a timing controller. The ramp voltage generator is configured to generate a ramp voltage. The ramp counter is coupled to the ramp voltage generator and configured to start counting when the ramp voltage generator generates the ramp voltage. The timing controller is coupled to the ramp voltage generator and the ramp counter respectively. When the ramp voltage is increased to be equal to a reference voltage, the timing controller compares an instant count value of the ramp counter with a default value and selectively calibrates a rising slope of the ramp voltage generated by the ramp voltage generator according to a comparing result of the instant count value and the default value.

Abstract: An amplifier circuit and a buffer amplifier are provided. The amplifier circuit includes an operational amplifier stage, an output stage, a first compensation capacitor, and a first decoupling circuit. The operational amplifier stage is coupled between a first input terminal, a second input terminal, a first control node, and a second control node. The first compensation capacitor is coupled between the output terminal and the first control node. The first decoupling circuit has a first switch, a first current source and a first ground terminal. The first switch is coupled to the first control node, and the first current source is connected between the first switch and the first ground terminal. The decoupling circuit is used for providing a discharging path for the first coupling current of the first compensation capacitor.
