Abstract: PURPOSE: A display driving circuit and a display device including the same are provided to reduce size by varying the layout of devices. CONSTITUTION: A logic control part(100) is formed at the central part of a semiconductor die(90). The logic control part controls a display driving circuit based on a control signal. Grayscale voltage generation parts(200a,200b) are formed at the edge part of the semiconductor die. The grayscale voltage generation part generates multiple grayscale voltages based on input voltage. Driving parts(300a,300b) are formed at the semiconductor die positioned between the logic control part and the grayscale voltage generation part. The driving part generates multiple driving voltages based on multiple grayscale voltages and data. [Reference numerals] (AA) First direction; (BB) Second direction

Abstract: PURPOSE: A power supply device for preventing latch-up of a charge pump and a method thereof are provided to adjust an inrush current for preventing latch-up by controlling a pulse width to reflect the result of comparing an input signal and a selection reference voltage. CONSTITUTION: An internal power supply(100) includes a primary voltage generator(150) and a pulse generator(500). The primary voltage generator generates a primary voltage and a feedback signal. The pulse generator generates a pulse from the feedback signal to operate a switch. A charge pump(200) generates a secondary voltage by using the primary voltage. An inrush current controller(300) is connected between the charge pump and the internal power supply. The inrush current controller controls pulse width modulation using a pulse width modulation control signal.
