Embodiment Construction

[0027] Reference will now be made in detail to preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0028] Recently, in order to overcome the disadvantages of the CCFL or the EEFL, active research has been conducted on a method of using a light emitting device (LED) as a backlight unit. LEDs increase color representation and increase the brightness of monochromatic light emission. In addition, LEDs have a fast response due to their fast response characteristics. Figure 3A with 3B The structure of a liquid crystal display device according to an embodiment of the present invention in which LEDs are used in a backlight unit is shown. Figure 3A is an exploded stereogram, Figure 3B yes Figure 3A disassembled sectional view.

[0029] Such as Figure 3A with 3B As shown, a liquid crystal display device according to an embodiment of the present invention includes a liquid crystal display panel 110 in which full-color display ...

Abstract

A liquid crystal display device includes a liquid crystal display panel, a light source having red, green and blue light emitting devices for supplying light to the liquid crystal display panel, the light source being divided into a plurality of regions, and a driving unit for separately driving red, green and blue light emitting devices in each region.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more specifically, to a liquid crystal display device and a driving method thereof. Background technique [0002] With the recent development of various portable electronic devices such as mobile phones, personal digital assistants (PDAs), and notebook computers, there is a demand for light-weight, thin-profile, and small-sized flat-panel display devices that can be used as displays in these devices is increasing. Research is being conducted on flat panel display devices, including liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, and vacuum fluorescent display (VFD) devices. Among these various devices, the LCD device is being most actively developed because of its simple mass production technology and its simple driving system that enables the product to provide high-quality display. [0003] Such a liquid crystal disp...
