Patent ID: 11955090
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A display device comprising:
a display panel including a plurality of pixels formed at intersections of gate lines arranged in a row direction and source lines arranged in a column direction;
a controller configured to generate a source control signal based on control signals received from an outside and convert image data received from an outside; and
a source driver configured to convert the image data converted by the controller into an image signal in response to the source control signal received from the controller, and provide the image signal to the source lines,
wherein the source driver includes an operational amplifier configured to amplify an input voltage to generate an output voltage;
a slew-rate compensating circuit including a boosting transistor, the slew-rate compensating circuit configured to generate a compensation current based on a difference between a voltage level of the input voltage and a voltage level of the output voltage and provide the compensation current to the operational amplifier through the boosting transistor; and
a buffer circuit including an offset blocking circuit configured to turn off the boosting transistor in response to the difference between the voltage level of the input voltage and the voltage level of the output voltage being less than a reference voltage level by providing a blocking current to a gate of the boosting transistor.
