Abstract
The present disclosure provides a pixel circuit and a display panel. The pixel circuit controls a conduction time of the driving module according to a connected triangle-wave analog signal, a time controlling analog signal, and a brightness control analog signal connected through an analog comparator, and controls a conduction degree of the driving module according to a brightness control analog signal connected through the analog comparator; thus a light-emitting time and/or luminous brightness of a light-emitting module is controlled, and multi-gray-scale display with a simpler pixel circuit structure is realized.
