摘要： A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.

摘要： The present invention discloses a method for compensating a brightness error of a flat panel display that compensates the input gray levels under a fixed sustain frequency by an error diffusion compensation circuit. After the gray levels are inputted to the flat panel display, the brightness will be outputted and measured to obtain an actual output brightness, and an ideal output brightness corresponding to the input gray level is calculated according to the linear proportional relation between the input gray level and its ideal output brightness, and then a look up table is created according to the actual output brightness and the ideal output brightness, such that the look up table can be used to overcome the gray level error as well as the error between the actual output brightness and the ideal output brightness of the flat panel display.

摘要： A driving electrode structure of a plasma display panel is described. The driving electrode structure has a driving electrode located in one luminant cell of each pixel. The driving electrode is formed on a transparent electrode and separated by a distance from the side of the transparent electrode adjacent to the edge of the luminant cells. The driving electrode has two branches coupled to a main electrode or a side electrode at the side of the transparent electrode adjacent to the edge of luminant cells. The driving electrode approximates the discharge center of the luminant cell to improve the driving characteristic.
