Problems solved by technology

In practice, the size of thin film transistors (TFTs) is usually limited by predetermined design rules
The size of thin film transistors (TFTs) is directly related to the aperture ratio, making it difficult for manufacturers of thin film transistors (TFTs) to increase the size of thin film transistors (TFTs) at will

Embodiment Construction

[0046] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0047] FIG. 3 is a timing chart illustrating a method of driving a liquid crystal display (LCD) according to a first embodiment of the present invention.

[0048] Referring to FIG. 3, a liquid crystal display (LCD) according to a first embodiment of the present invention sequentially applies scan pulse signals (SP1 and SP2) to respective gate lines to allocate a period corresponding to 2 horizontal periods to the first subframe. .

[0049] The scan pulse signals ( SP1 and SP2 ) include a first scan pulse signal SP1 and a second scan pulse signal SP2 . The second scan pulse signal SP2 is separated from the first scan pulse signal SP1 by 2 horizontal periods.

[0050] Scan pulse signals ( SP1 and SP2 ) are ...

Abstract

A method for driving a liquid crystal display (LCD) in which a single frame is divided into a plurality of sub-frames includes applying a first scan pulse signal and a second scan pulse signal to each gate line for each sub-frame, applying a first data signal to a data line by replying to the first scan pulse signal, applying a second data signal to the data line by replying to the second scan pulse signal, and switching on different light sources at each sub-frame, wherein the first and second scan pulse signals are simultaneously applied to different gate lines. Therefore, the LCD can transmit two scan pulse signals to a single gate line, thereby doubling a driving time of each gate line.

Description

technical field [0001] The present invention relates to a liquid crystal display (LCD), and more particularly, to a liquid crystal display (LCD) and a driving method thereof for applying a scan pulse signal twice to a gate line to ensure sufficient data charging time. Background technique [0002] Various flat panel displays with a thickness as thin as several centimeters (cm) have been widely used all over the world. A representative example of the flat panel display is a liquid crystal display (LCD). A liquid crystal display (LCD) has a low operating voltage and low power consumption, and can be used as a mobile device, so that it can be applied to various application fields, such as notebook computers, monitors, spaceships and airplanes, and the like. [0003] A liquid crystal display (LCD) includes a lower substrate, an upper substrate, and a liquid crystal layer formed between the lower substrate and the upper substrate. [0004] The upper substrate includes gate line...
