摘要： In a liquid crystal display apparatus, a set of write-in voltages are generated corresponding to a horizontal line signal of an input video frame so that they appear at end points of the column lines of a LCD panel. The row lines of the LCD panel are successively selected and the write-in voltages are supplied from the end points of the column lines to the liquid crystal cells of the selected row line for a variable write-in period. In order to compensate for shades-of-gray differences between the top and bottom of the LCD panel, the write-in period is increasingly varied as a function of the geometric distance from the selected row line to the end points of the column lines. The write-in period may be increasingly variable from a nominal value, or from a less-than-nominal value to the nominal value, or a combination of both.

摘要： A display apparatus is composed of a pseudo gray level data processor generating pseudo gray level data having m bits based on input gray level data having n bits. The pseudo gray level data processor includes a state variable generator generating a state variable data having n−m bits, based on lower n−m bits of the input gray level data, an adder calculating a sum of the lower n−m bits of the input gray level data and the state variable data to output a carry bit representative of carry-over of the sum, and a pseudo gray level data calculator generating the pseudo gray level data based on the input gray level data and the carry bit. The pseudo gray level data calculator defines the pseudo gray level data such that the pseudo gray level data equals upper m bits of the input gray level data in a first case when the carry bit is “0” and the input gray level belongs to first gray levels of the 2n gray levels, and such that upper m−1 bits of the pseudo gray level data equals upper m−1 bits of the input gray level data and LSB (least significant bit) of the pseudo gray level data is selected from “0” and “1” in a second case when the carry bit is “1” and the input gray level data belongs to the first gray levels.

摘要： A liquid crystal display control circuit receives a data enable signal DE in synchronization with per-line based display data from a computer, and thereby controls a liquid crystal display. A gate drive signal outputted from a gate driver 23 is generated according to a vertical clock signal VCK in synchronization with a rise of the signal DE. In order to avoid a variation in the period of charging the pixel electrodes which is caused by a delay in the rise timing of the signal DE and a delay in the signal VCK after the last line, a gate enable signal generation circuit 10 is provided in the liquid crystal display control circuit 1, whereby the extended output of the pulse of the gate drive signal caused by the above-mentioned delays is inhibited. This avoids display inhomogeneity caused by a variation in the data enable signal and the like.
