Abstract
The present invention relates to increasing the driving reliability of a flat panel display by including a protector in the power supply control unit that provides a driving voltage to the display panel. The protector prevents unexpected sequence mode transition of the memory by preventing transmission of an abnormal voltage caused by applied stress while providing a supplied voltage to the memory during normal driving.
Claims9
A driving circuit of a flat panel display comprising:
- a memory that operates in first and second sequence modes, and is set to the second sequence mode as a control terminal for selecting a sequence mode is grounded and outputs data corresponding to a driving voltage;
- a controller whose output terminal is coupled to the control terminal, and which determines the sequence mode of the memory;
- and
- a protector that electrically couples the output terminal and the control terminal in the second sequence mode, and prevents the memory from malfunctioning in the first sequence mode as an abnormal voltage is applied to the control terminal by decoupling the output terminal and the control terminal.
