Abstract: A resetting period of organic EL elements is divided to a discharge period for discharging residual charges of the organic EL elements and a precharge period for pre-charging the organic EL elements to predetermined potentials. First switch circuits provided for each of R (red), G (green) and B (blue) display colors are turned ON in the discharge period to discharge residual charges of the organic EL elements and second switch circuits provided for each of R, G and B display colors are turned ON in the precharge period to precharge the EL elements to a precharge potential lower than a light emission voltage of the organic EL elements. Values of finally set precharge voltages for R, G and B display colors are made different from each other.

Abstract: The present invention details a system for tracking writing motions internally to the pen (or other instrument) and communicating such motions to a general or specific purposes computer systems. In a preferred embodiment the present invention uses multiple tubes with electrically active material with viscosity surfaces in order to generate the necessary signals to determine the motion of the device in a targeted number of degrees. The data on movement is either supplemented with or oriented with magnetically-active thin film material which generates signals when the device is rotated. The data is then filtered and optionally processed and stored. The data then can be downloaded to a computer or other processing device to determine the motion of the pen or other tracking device.

Abstract: In conventional liquid crystal display controllers such as for portable telephone sets, the display is reduced in the stand-by state but the liquid crystal display duty is not changed, i.e., even the common electrodes of the rows that are not producing display are scanned, and the consumption of electric power is not decreased to a sufficient degree in the stand-by state. A liquid crystal display controller (2) includes a drive duty selection register (34) capable of being rewritten by a microprocessor (1), and a drive bias selection register (32). When the display is changed from the whole display on a liquid crystal display panel (3) to a partial display on part of the rows only, the preset values of the drive duty selection register and of the drive bias selection register are changed, so that the display is selectively produced on a portion of the liquid crystal display panel at a low voltage with a low-duty drive.

Abstract: A hold-type display apparatus is more likely to suffer the deterioration in the visibility of moving images due to the blur effect, compared to an impulse-type display apparatus. A single frame period is divided into a first period and a second period. Pixel data to be written to a pixel are written in a concentrated manner in the first period during a frame period. At this time, a write value for the pixel is set to twice a value of the image data in order not to lower the brightness of the images as a whole. However, only if the doubled value exceeds a range that can be displayed, the remaining pixel data are written in the second period. Thus, the change in display brightness approximates the impulse-type display apparatus, so that the visibility of moving images is improved.

LDD regions 15a through 15d of a switching TFT 201 formed in a pixel are formed such that they do not overlap gate electrodes 19a and 19b to provide a structure which is primarily intended for the reduction of an off-current. An LDD region 22 of a current control TFT 202 is formed such that it partially overlaps a gate electrode 35 to provide a structure which is primarily intended for the prevention of hot carrier injection and the reduction of an off-current. Appropriate TFT structures are thus provided depending on required functions to improve operational performance and reliability.

In the method, at least one pixel block each of which includes at least two data lines within the liquid crystal panel is set. The adjacent pixels in a gate line direction within the pixel block respond to data signals having the same polarity. The pixels within the other pixel areas except for the pixel block respond to data signals having a polarity contrary to the adjacent pixels at the left and right sides thereof. Accordingly, a current amount charged in the adjacent pixels having a large brightness difference is supplied always equally, so that the brightness difference between the adjacent pixels can be reduced to eliminate a noise pattern in the vertical direction.
