AI Technical Summary

Technical Problem

In existing technologies, operational amplifier (OP) compensation schemes cannot be flexibly started and stopped, resulting in wasted power consumption in normal scenes where compensation is not required, and poor compensation effect in some special scenes.

Method used

The screen detection module detects the degree of screen anomalies in real time. The first and second control branches are used to connect the ICA compensation module and the OP compensation module respectively, and connect them to the downstream load to realize on-demand activation and collaborative work, avoiding redundant operation.

Benefits of technology

It achieves intelligent compensation mode switching based on the degree of image anomaly, reduces system power consumption, and obtains the best compensation effect under severe anomalies, thereby improving the overall performance of the display panel and user experience.

Abstract

The application belongs to the technical field of display driving, and particularly relates to a control circuit and a display panel. The control circuit comprises a picture detection module configured to detect an abnormality degree of a current display picture and output a corresponding detection voltage according to the abnormality degree; a first control branch configured to turn on a signal path of the ICA compensation module and the rear-stage load when the detection voltage is in a first preset interval; and a second control branch configured to turn on a signal path of the OP compensation module and the rear-stage load when the detection voltage is in a second preset interval. Therefore, through the cooperative work of the picture detection module, the first control branch and the second control branch, the application realizes multiple compensation modes of only ICA compensation, only OP compensation and ICA and OP joint compensation according to the picture abnormality degree, avoids the redundant operation of the compensation function on the premise of improving the picture compensation effect, and reduces the system power consumption.
