The invention provides a mobile terminal writing tactile rendering method and device based on double-motor combined vibration, and belongs to the field of tactile feedback. In the data acquisition stage, acceleration, speed and normal force during interaction with a real material are acquired, main frequency and amplitude information of the acceleration are extracted and stored in a memory, and in the tactile rendering stage, the mobile terminal displays a writing application, receives a material type and roughness selected in the writing application and the type of a pen, and displays the received material type and roughness and the type of the pen. The on-pen processor inquires the memory according to the selected material type and the type of the pen and generates driving voltage to drive the on-pen motor to vibrate, and the in-panel processor drives the in-panel motor to vibrate by utilizing a material roughness adjusting rendering algorithm according to the selected material roughness. The method has the
