Abstract:
An LCD(Liquid Crystal Display) is provided to realize the reduction of size, by disposing a gate driving integrated circuit and a data driving integrated circuit at the same side of an LCD panel, thereby producing a compact display device. An LCD panel(200) displays an image. A plurality of data driving integrated circuits(DIC) are disposed at a first side of the LCD panel to drive data lines of the LCD panel. A gate driving integrated circuit(GIC) is disposed at the first side of the LCD panel. A plurality of signal transmission lines(299) are formed at a second side of the LCD panel, and electrically connected to the gate driving integrated circuit. A plurality of connection lines(280) connect the signal transmission lines and the gate lines respectively.

Abstract:
PROBLEM TO BE SOLVED: To provide a gate driver which increases picture quality by eliminating deterioration in stages, and also permits long-life driving. SOLUTION: The gate driver relating to this invention is provided with two or more stages which sequentially output shifted signals. Each of the two or more stages comprises: a 1st control part 21 to control a 1st node in response to a 1st scan signal and a 2nd scan signal; a 2nd control part 23 to control a 2nd node and a 3rd node in response to the 1st scan signal and the voltage on the 1st node; and an output part 25 to selectively output any of a 1st power source voltage and two or more clock signals in response to the voltages on the 1st through the 3rd node. Switching is carried out between a 2nd power source voltage and a 3rd power source voltage which are different from each other and supplied to the 2nd node and the 3rd node, respectively.

PROBLEM TO BE SOLVED: To provide a gate driver comprising stages of shift registers capable of improving reliability, a driving method for the gate driver, and a display device equipped with the same. SOLUTION: A gate driver comprises [N+2] cascade-connected stages (N: a positive number of ≥2) of shift registers configured to output signals sequentially such that an [n]th shift register (1≤n≤N) is reset by an [n+2]th output signal of an [n+2]th shift register which is two stages behind. In the present invention, a reset point of time is delayed and the output signal is speedily discharged to suppress defects in image quality due to malfunction, thereby improving a reliability of the product.
