The present invention relates to a navigation apparatus and method for a vehicle on which a traffic lane guide image is displayed so that an optimal traffic lane can be selected based on road information of a next section when a vehicle is driven. According to an aspect of the present invention, the shortest route between a current location of a vehicle and a desired destination is determined. When the vehicle turns left or right at the intersection, etc., an optimal traffic lane can be decided in advance. Accordingly, there is an advantage in that when a driver drives a vehicle, driving convenience can be improved.

A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.

A color filter array is provided that is capable of implementing full color with improved light-emitting efficiency and color coordinate values from a mixed light of blue and red, and an organic light-emitting display device using the same. A color filter array receiving a mixed light of blue wavelength light and red wavelength light to implement full color according to an embodiment of the invention comprises a red filter, a green filter, and a blue filter. The red filter includes a first color conversion material for converting the blue wavelength light into green light and red light and a green blocking material for blocking the green light. The green filter includes a second color conversion material for converting the blue wavelength light into green light and red light and a red blocking material for blocking the red light. The blue filter includes a red blocking material for blocking the red wavelength light.

Disclosed are a negative C-type compensation film and a method of preparing the same. The negative C-type compensation film includes a) a base layer, and b) a polymer layer comprising polyarylate prepared by a method comprising the step of copolymerizing divalent phenols, divalent aromatic carboxylic acid halides, and allyl bisphenol derivatives, the base layer and the polymer layer being sequentially layered. The compensation film is capable of being used for the negative C-type compensation film without a stretching process, significantly reduces the thickness of the compensation film, and has significantly improved interlayer adhesion force in a multilayer structure.

The present invention relates to a catalyst for the decomposition of exhausted perfluoro-compounds (PFCs) and a catalytic decomposition method of PFCs by using the same. More particularly, the present invention relates to a PFC decomposition catalyst prepared in such a manner that a surface of aluminum oxide is loaded with phosphorous (P) component at a aluminum/phosphorous mole ratio of 10 to 100 and a decomposition method of PFCs by using the catalyst. The present catalyst can be decomposed PFCs at 100% rate exhausted from semiconductor manufacturing industry and thus prevent the release of PFCs having high global warming potential into atmosphere.

Provided are a method and apparatus for driving a PDP for widening a driving margin and improving contrast. The method for driving a PDP includes a first step of forming wall charges in cells with a set-up discharge using a set-up signal in a first sub-field and erasing the wall charges with a set-down discharge using a first set-down signal to initialize the cells, and a second step of erasing the wall charges with a set-down discharge generated using a second set-down signal different from the first set-down signal in a second sub-field, to initialize the cells. The method and apparatus for driving a PDP uniformly initialize sub-fields to widen the driving margin of PDP and remove a set-up discharge in at least one sub-field to improve the contrast of PDP.

Disclosed herein is a method and apparatus for driving a plasma display panel, which improves contrast characteristics and preventing a low discharge making a cell non-luminous at a specific gray scale. The method for driving a plasma display panel includes the steps of initializing a cell by supplying a first write voltage and an erase voltage to a scanning electrode during a reset interval of the n-th sub-field; initializing the cell by supplying the erase voltage and a second write voltage which is higher than a sustaining voltage and lower than the first write voltage to the scanning electrode during a reset interval of the (n+1)-th sub-field; selecting the cell by supplying the scanning voltage to the scanning electrode and supplying a data voltage to an address electrode during an address interval of each of the n-th and (n+1)-th sub-fields; and alternatively supplying the sustaining voltage to the scanning and sustaining electrodes during a sustaining interval of each of the n-th and (n+1 )-th sub-fields.
