A high voltage generation circuit for a display driving circuit chip is provided to reduce a manufacturing cost of a display system by outputting a stabilized high voltage without a voltage stabilizing system. A high voltage generation circuit(100) for a display driving circuit chip includes a power voltage input unit(101), an inputted voltage detection unit(103), and a boost circuit unit(105). The power voltage input unit receives a power voltage of a battery. The inputted voltage detection unit detects the inputted power voltage. The boost circuit unit determines a boost ratio according to the detected voltage, boosts the voltage, and outputs the boosted voltage to a panel driving circuit. The boost circuit unit includes a boost ratio determination unit(105-1) and a boost unit(105-2). |
