Problems solved by technology

However, the problem with related technologies is that if the FFC is plugged and unplugged in a power-off state, the Takt Time of the switching power supply is easy to ignore; if the FFC is plugged and unplugged in a power-off state, it will often lead to disordered PIN sequence connection and short circuit. Cause irreversible damage to the Panel, unable to light up, affecting the yield to a certain extent

Abstract

The invention discloses a display device and its plug-in protection device. The plug-in protection device includes: at least one first interface component; at least one second interface component; at least one connector, and the first end of each connector is connected to the corresponding The first interface assembly is adapted, and the second end of each connector is adapted to the corresponding second interface assembly; the protection module, the protection module passes at least one first interface assembly, at least one second interface assembly, at least one The connectors constitute a protection circuit, and the protection circuit generates a preset electrical signal when the first end of each connector is connected to the corresponding first interface component and the second end of each connector is connected to the corresponding second interface component; the power supply The control module, the power control module is connected to the protection module and the power module of the display device respectively, and the power control module controls the power module to output the first preset power according to the preset electrical signal, thereby preventing the PIN sequence caused by plugging and unplugging the connector with power. Disorder and short circuit.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a plug-in protection device for a display device and a display device having the same. Background technique [0002] The flexible flat cable FFC is indispensable as a bridge connecting Panel and T-Con. In the related art, a large number of FFC plugging and unplugging operations are required in the panel production process and module detection. However, the problem existing in the related art is that if the FFC is plugged and unplugged in a power-off state, the Takt Time of the switching power supply is easily ignored; if the FFC is plugged and unplugged in an uninterrupted state, the PIN sequence connection will be disordered and a short circuit will occur. As a result, the Panel is irreversibly damaged and cannot be lit, which affects the yield to a certain extent. SUMMARY OF THE INVENTION [0003] The present invention aims to solve one of the technical proble...
