Embodiment Construction

[0024] Hereinafter, exemplary embodiments of the present invention are explained in detail with reference to the accompanying drawings.

[0025] figure 1 The block diagram of is showing a liquid crystal display device according to an exemplary embodiment of the present invention.

[0026] see figure 1 , the liquid crystal display device 500 includes a liquid crystal display panel 100 , a gate driving circuit 210 , a data driving circuit 220 , a controller 300 , an external interface 400 and an internal interface 450 .

[0027] The liquid crystal display panel 100 includes gate lines GL1 to GLn (where n represents a positive integer), data lines DL1 to DLm (where m represents a positive integer) intersecting the gate lines GL1 to GLn, and A plurality of pixels are formed at a pixel region defined by GLn and the data lines DL1 to DLm. Each pixel has a thin film transistor (Tr) and a liquid crystal capacitor (Clc). In the first pixel region, the gate of the thin film transist...

Abstract

In a display apparatus, a display part displays images in response to driving signals, and a driving part outputs the driving signals to the display part in response to control signals. A control part includes circuits outputting the control signals to the driving part. Circuits of the control part are connected to an interface for a data communication between the circuits. Thus, the circuits may generate flexible data because the master electrically connected to the digital interface controls the circuits.

Description

technical field [0001] The invention relates to a display device. In particular, the present invention relates to a display device with improved productivity. Background technique [0002] Generally, a liquid crystal display device includes a liquid crystal display panel for displaying an image in response to a data signal and a gate signal, a data driver for outputting the data signal, and a gate driver for outputting the gate signal. The liquid crystal display device also includes a timing controller, a nonvolatile memory, and a DC-DC converter for driving a data driver and a gate driver. [0003] The timing controller receives image data and various external control signals, and applies internal control signals to the data driver and the gate driver. The DC-DC converter changes an externally supplied power supply voltage into a driving voltage to drive the data driver and the gate driver. [0004] The liquid crystal display device also includes a common voltage generat...
