Abstract: This present invention provides a liquid-crystal panel that presents a high-density wiring while maintaining reliability of the wiring. Odd-numbered scanning lines are connected to a first wiring group while even-numbered scanning lines are connected to a second wiring group. Each of the scanning lines is supplied with a scanning signal the polarity of which is inverted every horizontal scanning period. Among wirings forming the first wiring group and the second wiring group, a line-to-line voltage between any adjacent wirings becomes zero volt for a majority of the time. Accordingly, degradation of the wirings due to electrolytic corrosion is controlled even if the spacing between the wirings is narrowed.

Abstract: In an electrooptical apparatus having a function allowing part of a display screen to be in a display state and allowing the other to be in a non-display state, for a non-display region, application voltages for scanning electrodes are fixed at non-selection voltages, and application voltages for signal electrodes are fixed at voltages similar to the case of a full-screen ON-display or a full-screen OFF-display at least in a predetermined period; therefore, power consumption in the partial display state can be reduced.

Abstract: To enhance image quality of a moving image when an electrooptical device presents the image based on an electrooptical change in an electrooptical material. Pixels 120 which are turned on within one horizontal scanning period (1H) are four rows only, while the four rows are successively shifted downward every horizontal scanning period. In this way, the pixels are turned off within a short period of time, thereby reducing a chance of an image being recognized as an after image.

Abstract: A system and method for driving a thin film diode (TFD) inclusive AMLCD or imaging device (e.g. x-ray imager) includes providing each pixel with a pair of select lines and a single data line. Drive schemes are provided which increase the circuits tolerance for spacial and temporal variations in diode (e.g. MIM diode) characteristics, improve response time, increase the circuit's tolerance for RC delays on data lines, and reduces the potential for crosstalk or image retention. In certain embodiments, where each pixel includes a pair of select lines, and a single data line, the select voltage on the first select line alternates between VS+Voffset and VS−Voffset for subsequent frames, while the select voltage on the other select line alternates between −VS+Voffset and −VS−Voffset for subsequent frames, thereby allowing voltage at the common node to be added to the data voltage. Drive schemes herein are used in conjunction with row inversion driving of pixel arrays, and some embodiments are also compatible with column inversion, frame inversion, and/or pixel inversion.
