Abstract

The invention provides a voltage converting unit including a converting module part, a temperature compensating part, a first gate driving signal generating part and a second gate driving signal generating part, whereby an image display quality is improved. The converting module part generates a gate driving pulse based on an externally provided voltage. The temperature compensating part generates a reference voltage based on a primary reference voltage with respect to a temperature. The first gate driving signal generating part generates a first gate driving signal based on the gate driving pulse and the reference voltage. The second gate driving signal generating part generates a second gate driving signal based on the gate driving pulse and a ground voltage.

Description

technical field [0001] The present disclosure relates to a voltage conversion device and a display device having the voltage conversion device. More particularly, the present disclosure relates to a voltage conversion device that is not affected by temperature changes, and a display device having the voltage conversion device that can improve image display quality. Background technique [0002] The display device displays images using electrical signals processed by the information processing device. A flat panel display device is a display device having various characteristics such as small size, light weight, and high resolution among display devices. [0003] A liquid crystal display (LCD) device is a flat panel display device that uses the photoelectric properties of liquid crystals to display images among flat panel display devices. [0004] The LCD device includes a display panel assembly and a backlight assembly. The display panel assembly i...
