A driving method of the display panel and a driving apparatus are provided. The method includes: during a display period of one frame, acquiring an actual charge grayscale of a pixel unit of an Nth row and a target grayscale of a pixel unit of an N+1th row, wherein the pixel unit of the Nth row and the pixel unit of the N+1th row are connected to a same data line; according to the actual charge grayscale of the pixel unit of the Nth row and the target grayscale of the pixel unit of the N+1 th row, acquiring an over drive grayscale of the pixel unit of the N+1 th row; and driving the pixel unit of the N+1 th row using the over drive grayscale. Thus, the over drive grayscale of the pixel unit of the N+1 th row is more accurate, thereby increasing a charge rate of the pixel unit.

A multi-wavelength single-frequency optical fiber laser source for a laser radar system includes a resonant cavity composed of a high-reflectivity chirped optical fiber grating, a high gain optical fiber and a low-reflectivity chirped optical fiber grating, a single-mode semiconductor pump laser served as a pump light source, an optical wavelength division multiplexer, an optical coupler, an optical isolator, an optical circulator, an optical filter module, and a semiconductor optical amplifier. The pump light source performs optical fiber core pumping with respect to the high gain optical fiber. A portion of the wide-spectrum laser is filtered by the optical filter module to obtain a wavelength corresponding to a specific central frequency. Multi-wavelength laser lasing with a narrow linewidth and single longitudinal mode is implemented by combining a short linear resonant cavity structure and the optical filter module.
