ABSTRACT:
An exemplary liquid crystal display (LCD) (20) includes: a gate driving integrated circuit (IC) (22) for scanning an LCD panel (24) of the LCD; a data driving IC (23) for providing a plurality of gradation voltages to the LCD panel; a primary control circuit board (21) configured for providing the operation voltage to the data driving IC; and a flexible printed circuit board (25) connected between the LCD panel and the primary control circuit board. The data driving IC includes a voltage detecting circuit (230), which detects an operation voltage applied to the gate driving IC and is configured to provide an all-scanning signal to the gate driving IC.
