Title: Control method of contrast ratio of pdp tv
Inventor: YU SANG WOOK
IPC: H04N5/57
Filed: 1998-12-30
Abstract: PURPOSE: A control method of contrast ratio of PDP TV is provided to prevent the degradation of image quality due to overvoltage by reducing preset contrast ratio when an APL(Average Picture Level) input voltage is over a threshold value. CONSTITUTION: A control method of contrast ratio of PDP TV comprises steps of: calculating corresponding APL input voltage and comparing the calculated APL input voltage with preset APL threshold value; A/D converting the calculated APL input voltage if the voltage is over the threshold value; calculating the reduced amount of contrast ratio on the basis of the voltage excess level of the converted APL input voltage and a preset contrast ratio; generating updated contrast ratio obtained by subtracting the preset contrast ratio by the reduced amount to output the ratio to a driver for scan/sustain; repeating the second to forth steps until the calculated APL input voltage becomes less than the preset APL threshold value; and recovering the updated contrast ratio to the preset contrast ratio if the voltage becomes less than the threshold value.

Title: Optical disk with rewritable area and read-only area
Inventor: ISHIDA TAKASHI
IPC: G11B7/00
Filed: 1997-06-24
Abstract: PURPOSE: An optical disc is provided whereby positioning conditions for the border area between rewritable area and read-only area are defined so that mixing data from both areas does not occur, and the rewritable area and the read-only area are positioned substantially adjacent, or via a land having a predetermined width, so that the efficiency of using the optical disc does not deteriorate. CONSTITUTION: An optical disc is disclosed to have rewritable area(2), read-only area(3) and rewritable area(4) near the transition line(26). The transition line(26) is an imaginary line defining the transition between land(11) and groove(12). And a rewritable track always begin with a groove and always end with a groove. The pitch(Pa) between land(11) and the adjacent groove(12), i.e., the distance between the center line of land(11) and the center line of groove(12), is 0.74 micro meter. This means that the pitch between lands(11), and between grooves(12), is twice the track pitch or 1.48 micro meter. The surface level of the land is the same as the level of the read-only area side of the boundary line. As a result, the boundary line between the rewritable area and the read-only area will never contact the groove. And the transition from the end track land(11) and the beginning of the read-only area(3) following thereafter also occurs at this transition line(26). The transition between the rewritable area and the read-only area thus always occurs at transition line(26). So the mixing data from both areas does not occur.
