Benefits of technology
[0025]An object of the present invention is to provide an LCD module and driving apparatus thereof having an improving display quality.
Problems solved by technology
In addition, wavelengths of other colors in addition to the colors of red R, green G, and blue B are produced, thereby deteriorating color purity, as shown in FIG. 5.
However, if the thickness of the color filter layer 25a is increased in order to increase the color purity, then the brightness of the LCD panel 6 is lowered by an amount of about 10%˜about 20%, which results in a deteriorated display quality of the LCD module 1.
Thus, display quality deteriorates.
In addition, since the number of data ICs increases as the number of color pixels increases, production costs for the LCD module 1 increases.
Moreover, since processes for forming the color filter layers 25b and 25c are complicated, low yield of the LCD module 1 results.

Abstract
A liquid crystal display module includes a liquid crystal display panel, a plurality of lamps for irradiating a first light onto the liquid crystal display panel, and a back light unit including a plurality of light emitting diode arrays, each of the light emitting diode arrays having a plurality of light emitting diodes arranged between the lamps to irradiate a second light onto the liquid crystal display panel.
Description
[0001]The present invention claims the benefit of Korean Patent Application No. P2003-43808 filed in Korea on Jun. 30, 2003, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a display module and a driving apparatus thereof, and more particularly, to a liquid crystal display module and a driving apparatus thereof.[0004]2. Description of the Related Art[0005]In general, liquid crystal display (LCD) devices are commonly used in display devices because of their light weight, thin profile, and low power consumption. For example, the LCD device are commonly used in office automation devices and audio / video devices. The LCD device displays images by adjusting light transmissivity according to image signals supplied to a plurality of control switches arranged in a matrix configuration.[0006]Generally, LCD devices include an LCD module and a driving circuitry for driving the LCD module. The LCD module c...
