摘要： In a display device of the present invention, a total fluctuation calculation portion (23) included in a display control circuit (200) calculates total amounts of potential fluctuations of drive video signals to be applied to video signal lines during one frame period based on external display data signals (DATs). For a pixel formation portion to be provided with a display data signal (DATp) (corresponding to the next display row of the previous frame) received from frame memory (22), a data correction portion (24) performs correction to compensate for impact to be caused by potential fluctuations of an opposite video signal line adjacent but not connected to the pixel formation portion. As a result, the instant delta-arrangement color display device allows horizontal streaks, which are caused by potential fluctuations of opposite video signal lines as mentioned above, to be reduced or eliminated using a simplified configuration.

摘要： In one embodiment of the present invention, a liquid crystal display device groups video signal lines SL1 to SLn every 12 video signal lines in order of arrangement and drives video signal lines in each group in a time division manner during a horizontal scanning period. The order of driving video signal lines in each group varies between an even frame and an odd frame, and for each line, in one of the frames, even-numbered video signal lines are driven earlier and in the other one of the frames, odd-numbered video signal lines are driven earlier. The first and last video signal lines to be driven correspond to blue. Accordingly, the numbers of times the video signal lines are influenced by push-up are limited to two for the even frame and zero for the odd frame and vice versa, whereby vertical streaks that occur at low temperatures are prevented, and insufficient charge is caused to occur only in video signal lines corresponding to blue, which makes it difficult for humans to recognize degradation in image quality aue to insufficient charge.

摘要： Provided is a display apparatus wherein a sustain capacitance wire is shared between two rows of pixels to prevent the reduction in aperture ratio and the reduction in yield, and further the capacitive coupling drive can be performed. The display apparatus comprises: pixels arranged in a matrix of n rows and m columns (where n and m represent integers equal to or greater than two); m source lines and n gate lines provided in a grid pattern; and a sustain capacitance unit formed in a boundary area between odd-numbered and even-numbered rows of pixels. The sustain capacitance unit comprises: a sustain capacitance wire shared between the odd-numbered and even-numbered rows of pixels; an insulating film; an opposite electrode used for the odd-numbered row of pixels; and an opposite electrode used for the even-numbered row of pixels. The odd-numbered row of pixels each have a pixel electrode electrically connected to the opposite electrode used for the odd-numbered row of pixels, and the even-numbered row of pixels each have a pixel electrode electrically connected to the opposite electrode used for the even-numbered row of pixels. The polarity of the potential of the pixel electrode is reversed for every two rows of pixels sharing the sustain capacitance wire, while the potential of the sustain capacitance wire is varied to vary the potentials of the pixel electrodes of the two rows of pixels, thereby performing the capacitive coupling drive.

摘要： The subject invention discloses a scanning direction control circuit, which includes a bidirectional shift register in which shifting direction is switched in accordance with a switching signal L/R, which is step-upped by a level shifter when having lower amplitude than the driving voltage. The scanning direction control circuit includes a latch circuit between the level shifter and the bidirectional shift register, and a control circuit causes the latch circuit to carry out latching operation after shifting operation of flip-flops constituting the bidirectional shift register is completed in response to output signals of the flip-flops. The control circuit brings the level shifter into active state in a period before, at and after the latching timing, and brings the level shifter into inactive state in the remaining period. With this arrangement, the switching signal L/R can be supplied at a predetermined timing regardless of external input timing thereof, with low power consumption.
