    摘要: A scaling-up control method and a scaling-up control apparatus are used in a display device. The display device includes a scaler for converting an original image signal into an output image signal by performing a linear interpolation. Moreover, by utilizing a global locking mechanism and a local locking mechanism to perform the linear interpolation to determine the actual position of the interpolated pixel, the position error of the pixel position is largely reduced. Since the difference between the calculated pixel value and the ideal pixel value is reduced, the imaging quality of the output image signal is enhanced.

    摘要: A pixel of the LCD is driven according to a precharge pixel value and a compensation pixel value both being generated from a pixel value during a precharge field and a compensation field respectively. A precharge driving voltage corresponding to the precharge pixel value, and a compensation driving voltage corresponding to the compensation pixel value is then determined and used to drive the pixel. The lightness of the pixel driven according to the precharge pixel value and the compensation pixel value is substantially the same as the lightness of the pixel if driven according to the pixel value. The precharge field comes before the compensation field when the precharge pixel value is larger than the compensation pixel value, and the compensation field comes before the precharge field when the compensation pixel value is larger than the precharge pixel value.

The method comprises the step of providing a gray level mapping table, which maps the signal gray levels from 0 to N into mapped gray levels from 1 to N−1 level. Thereafter, the mapped data is fed into over-voltage compensation circuit. The over-voltage compensation circuit then implements process of the gray level ascending or gray level descending while the previous frame turns into current frame with a varied gray level.
