Embodiments of the present application disclose a method and a device of detecting a low voltage differential signal output to a liquid crystal display panel. In the method, the low voltage differential signal is decoded into a pixel color data signal; and then blanking signals of the pixel color data signal are counted.

Method and device for detecting low voltage differential signal

Provided are a common voltage adjustment circuit for a display panel and a display apparatus. The adjustment circuit comprises: a filter unit () configured to filter a PWM signal provided externally and provide a DC voltage signal obtained through the filtering to a first voltage clamp unit; a first voltage clamp unit () configured to adjust the DC voltage signal to obtain a first adjusted signal and provide the first adjusted signal to a feedback amplification unit; a feedback amplification unit () configured to amplify the first adjusted signal to obtain a first amplified signal and provide the first amplified signal to a second voltage clamp unit; and a second voltage clamp unit () configured to adjust the first amplified signal to output a second adjusted signal and provide the voltage value of the second adjusted signal to the display panel. The adjustment circuit can rapidly and precisely adjust the common voltage of the display panel to reduce the flicker phenomenon during the displaying of the display panel.
