Abstract
A display panel and a compensation circuit are provided. The display panel has a periphery region and a display region. The display panel includes pixel columns and a threshold voltage compensation circuit. The pixel columns are disposed in the display region. The threshold voltage compensation circuit is disposed in the periphery region. The threshold voltage compensation circuit receives a compensation voltage, outputs threshold voltage information of a compensation transistor based on the compensation voltage, and generates compensated display data based on the threshold voltage information and display data.
