Abstract
A pixel circuit, a display panel and a method for improving low gray-level uniformity for a display panel are provided. A feedthrough effect can be effectively reduced by increasing resistance value of a resistor line between a source of a switching thin-film transistor and a gate of a driving thin-film transistor. Low gray-level uniformity of the display panel is improved. Quality of the display panel is enhanced.
