Abstract: A backlight driving method and a display panel are provided. The backlight driving method provided by the present application uses pulse width modulation technology to modulate a low-level pulse width of a scan signal. By increasing a low-level pulse width to increase the pulse period, a number of high-level pulses is reduced, thereby reducing a high-level pulse time. Therefore, a time for a TFT to receive a high-level voltage is also reduced, thereby improving a stability of the TFT and also improving a problem of a threshold voltage drift of the TFT.

Abstract: A method and system for displaying a street view map are provided. The method includes: acquiring a site scene image of a street view; determining that the site scene comprises a three-dimensional model, acquiring the attribute information of the three-dimensional model and the stereoscopic information of the site scene; in the position coordinates of the real object in the site scene relative to the site scene, identifying and utilizing the position coordinates of the real object relative to the site scene identical to the position coordinates corresponding to the three-dimensional model contained in the attribute information of the three-dimensional model as position coordinates of the three-dimensional model relative to the site scene; and loading the three-dimensional model to render the site scene image.
