摘要： When displaying moving images by using liquid crystal panels and others, a problem exists in that tail streaks occur, and image degradation is resultantly caused. To solve this problem, an echo suppression circuit divides a video signal into a pair composed of two successive frames for comparison between these two frames in signal level for the purpose of suppressing an echo phenomenon occurring when a liquid crystal panel displays video signals including moving images. If these two frames are not the same in signal level, the signal is accordingly corrected so as to equalize the signal level of these frames. Based on the video signals and others corrected by the echo suppression circuit, a controller operates the liquid crystal panel with AC drive through a source driver and a gate driver. As such, the drive voltage used to operate the liquid crystal panel with AC drive is adjusted so as to be balanced between positive and negative. In this manner, the tail streaks are prevented when displaying moving images.

摘要翻译：当使用液晶面板等显示运动图像时，存在发生尾部条纹的问题，并且导致图像劣化。为了解决这个问题，回波抑制电路将视频信号分成由两个连续的帧组成的对，用于在信号电平的这两个帧之间进行比较，以便抑制当液晶面板显示包括运动图像的视频信号时发生的回波现象。如果这两个帧在信号电平上不相同，则相应地校正信号以使这些帧的信号电平相等。基于视频信号和由回波抑制电路校正的其他信号，控制器通过源极驱动器和栅极驱动器通过AC驱动来操作液晶面板。因此，用于操作具有AC驱动的液晶面板的驱动电压被调节以便在正负之间平衡。以这种方式，当显示运动图像时可以防止尾部条纹。

摘要： A liquid crystal screen display is disclosed which is capable of restraining occurrence of display unevenness. In the display of the invention, a conductive member to which a negative voltage is applied is placed between a substrate and an alignment layer so as to be in partial contact with the alignment layer. Uneven ion distribution attributable to ion generation within broken or pin hole parts of an overcoat film is restrained, for instance, by exposing gate signal lines etc. to the alignment layer so that ions are intentionally generated in the regions of the liquid crystal layer corresponding to the exposed regions.

摘要： The curing, by UV-light irradiation, of a sealing resin after injecting liquid crystal is made reliable. The display characteristics and the like of an in-plane electric field mode liquid crystal element are improved. To resolve these problems, the viscosity of the sealing resin is lowered, while bubbles mixed in the sealing resin are eliminated by ultrasonic waves, for example. Also, a means for eliminating ions and charges in the liquid crystal layer is devised.

摘要： Disclosed is a liquid crystal display capable of ensuring brightness necessary for achieving satisfactory display by increasing ratio of light-emitting time to one frame period. A liquid crystal display is adapted to have a period (non-video signal write period) required for writing non-video signals different from video signals onto all the pixels before a video signal write period. In the non-video signal write period, the non-video signals are written onto the respective pixels, thereby starting response of the liquid crystal before the start of the video signal write period. In the non-video signal write period, a backlight is turned off, and thereby image degradation is prevented even when the non-video signals are written onto the respective pixels.

摘要： A liquid crystal display element driving method or a liquid crystal display device uses a liquid crystal display element having a plurality of pixels constituting a screen; divides a frame period into a plurality of write periods and outputs gate signals to select the pixels sequentially during the write periods; forms each of source signals such that the source signal includes a picture signal and a non-picture signal respectively assigned for the write periods; writes each of the source signals corresponding to the selected pixels to each of the pixels with its polarity being alternated; and displays an image responsive to the source signals on the screen of the liquid crystal display element in such a manner that a transmittivity of liquid crystals of each of the pixels is controlled in accordance with the written source signal, wherein the non-picture signal having a polarity identical to that of the picture signal to be written subsequently is written to the pixels.
