Display panel driving circuit and method for capturing driving circuit error information thereof

摘要

The invention provides a display panel driving circuit and a method for capturing error information thereof. The display panel driving circuit includes a driving circuit, a pixel circuit and a timing controller circuit. The method includes: obtaining LED error information indicating errors caused by an LED of the pixel circuit; driving the LED by the drive circuit to obtain LED and driving circuit error information; obtaining driving circuit error information according to the two error information. The timing controller circuit records the error information and compensates LED attenuation by using the error information.
