Embodiment Construction

[0017] Exemplary embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, this invention may be embodied in various different forms and should not be construed as limited to the embodiments set forth herein.

[0018] FIG. 1 is a block diagram showing a driving device according to an exemplary embodiment of the present invention.

[0019] Referring to FIG. 1 , the driving device 100 includes: a timing controller 110 , a memory 120 , a phase synchronization loop 130 , a data driver 140 and a gate driver 150 .

[0020] The timing controller 110 receives a vertical sync signal Vsync, a first horizontal sync signal Hsync1, a first clock (clock, also referred to as a clock signal) CK1 and a first image data signal Data1 from an external device (not shown). In one embodiment, the timing controller 110 and the external device communicate with each othe...

Abstract

A display device includes a timing controller, a data driver and a gate driver. The timing controller receives a first clock and an image data signal and outputs a second clock having a lower frequency than that of the first clock and the image data signal. The data driver receives the image data signal in synchronization with the second clock and converts the image data signal into a pixel voltage in response to a data control signal. The gate driver outputs a gate voltage in response to a gate control signal generated based on the second clock.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 2006-71625 filed on July 28, 2006, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The invention relates to a driving device and a display with the driving device, more specifically, to a driving device capable of increasing charging rate and reducing electromagnetic interference. Background technique [0004] A liquid crystal display includes a liquid crystal display panel having two display substrates and a liquid crystal layer interposed between the two substrates. The liquid crystal display panel applies an electric field to the liquid crystal layer and adjusts the strength of the electric field to control the transmittance of light passing through the liquid crystal layer, thereby displaying desired images on the liquid crystal display panel. [0005] The liquid crystal display panel is provided wi...
