Abstract

The invention provides a protection device for live hot swapping of lasers, including a load module, a signal module and a control module, the signal module is electrically connected to the load module, and the signal module is used to input preset signals to the load module, wherein, in the present invention, the Electrically connect the control module to the load module to obtain the working parameters of the load module, and if the control module judges that the working parameter is less than the threshold parameter, then control the current flowing into the load module to be 0, so that the load module is in a power-off state, which can avoid the load The module is still in the energized state when the circuit is disconnected, thereby avoiding the instantaneous "hot swap" action of the load module from disconnection to connection, and reducing the risk of damage to the load module.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the field of display panel manufacturing technology, and in particular to a protection device for hot plugging and unplugging of lasers. Background technique [0002] Laser has become an ideal light source for optical communication due to its good directionality, coherence and high brightness. With the development of optical communication technology, the application of laser is becoming more and more common. [0003] Among them, the laser is driven by a constant current source to emit light; however, during the working process of the constant current source, due to the reliability of the laser connection and the inevitable mechanical jitter and other issues, the moment the laser as the load is converted from an open circuit to an open circuit, That is, the "hot plug" action causes a huge current to flow through the laser, causing damage to the laser. [0004] Therefore,...
