Abstract

The present application provides a motor control circuit, a driving device and a display device. By arranging a protection circuit between the control circuit and the motor, the switch circuit is connected to the protection circuit at the same time; The signal output by the switch tube in the protection circuit to the motor is the signal corresponding to the motor entering the sliding state. Using the above circuit design, when the moving parts driven by the motor are in place, the switch circuit is triggered, so that the motor can directly enter the coasting state, without the need for the control circuit to issue a signal to control the motor to stop, thereby solving the software control method. Low safety factor, complex control logic and control delay.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201910498039.3 and the title of the invention "motor control circuit, driving device and display device" submitted to the China Patent Office on June 10, 2019, the entire contents of which are incorporated herein by reference Applying. technical field [0002] The embodiments of the present application relate to the field of circuit technology, and more specifically, to a motor control circuit, a driving device, and a display device. Background technique [0003] At present, since the display device can provide users with playback images such as audio, video, and pictures, it has attracted widespread attention from users.
