DISPLAY DEVICE: abstract simplified (18114241)

• This abstract for appeared for patent application number 18114241 Titled 'DISPLAY DEVICE'

Simplified Explanation

The abstract describes a display device that consists of a display panel, a control circuit board, cables, an abnormal coupling detector, and a voltage supply controller. The control circuit board has a power management circuit that supplies a driving voltage to the display panel. The first cable connects the power management circuit to the first wiring of the display panel, and the second cable connects it to the second wiring. The abnormal coupling detector is connected between the first and second wirings and generates protection signals based on the voltage difference between them. The voltage supply controller counts these protection signals and sends a shutdown signal to the power management circuit, causing it to stop supplying the driving voltage.

Original Abstract Submitted

A display device includes: a display panel including first and second wirings; a control circuit board spaced apart from the display panel and including a power management circuit which provides a driving voltage to the first and second wirings; a first cable coupled to the control circuit board and electrically connecting the power management circuit and the first wiring; a second cable coupled to the control circuit board and electrically connecting the power management circuit and the second wiring; an abnormal coupling detector connected between the first and second wirings and generating first and second protection signals based on a difference between a first voltage of the first wiring and a second voltage of the second wiring; and a voltage supply controller counting the first and second protection signals, and providing a shutdown signal to the power management circuit such that the power management circuit stops providing the driving voltage.
