摘要： A display panel and a driving method for the same are disclosed. The display panel includes gate lines, data lines, gate driver, and data driver. The gate lines and the data lines define multiple pixel areas. Each pixel electrode correspondingly connects with one gate line and one data line. Pixel areas connected with a same gate line allow lights having a same color to pass through. When displaying a picture, the gate driver sequentially drives the multiple gate lines, and the data driver applies a same gamma voltage on the pixel areas connected with the same gate line. The present invention can drive the display panel by a lower hardware cost such that light transmittance rates of sub-pixels corresponding to different colors when same grayscale voltages are applied are the same.
