摘要： A swash plate type compressor has a rotary shaft, an inclined swash plate for rotation with the shaft, and a plurality of pistons connected to the swash plate. Each piston defines at both ends thereof a pair of working chambers. The piston reciprocates while being subjected to a swing motion concomitant with the rotation of the swash plate, to suck a fluid into the working chambers for compression. The swash plate is mounted on the shaft through a support unit which serves to selectively vary the inclination of the swash plate and shift the center of rotation of the swash plate along the shaft. The fluid is introduced from a suction passage through and around the swash plate to suction chambers formed adjacent the working chambers. A bypass passage is formed to directly communicate the suction passage with the suction chamber on one side of the shaft while bypassing the swash plate. When the inclination of the swash plate is decreased and the rotational center position thereof is shifted so that substantially no compression of fluid is completed in the working chambers on the one side of the shaft to decrease the displacement of the compressor, the fluid flows in the one side suction chamber through the bypass passage responsively to the flow of fluid toward another side working chambers to lubricate and cool sliding parts for the shaft.

摘要： Overdrive over multiple frames is made more efficient in a display device drive circuit that drives a display device so slow in response that target brightness is not reached even after overdrive is performed for one frame. When a display gray scale is changed from a first gray scale to a second gray scale, a display driving device varies overdrive driving voltage according to the number of frames since the point of time of the change. This makes it possible to obtain high-speed luminance response. When the number of frames for which an identical image is continuously displayed is known beforehand, the number of frames is set in a display pattern setting register and a function of detecting timing of a change of images is provided. This enables efficient overdrive. At low temperature, further, a display image is updated once for several frames according to temperature information. This enhances the visibility of the image.

摘要翻译： 在显示设备驱动电路中，即使在一帧执行过驱动之后，在显示设备驱动电路中对驱动显示设备如此慢的响应也不会达到目标亮度，因此在多个帧上进行过载。 当显示灰度级从第一灰度级变为第二灰度级时，显示驱动装置根据从改变的时间点开始的帧数来改变过驱动驱动电压。 这使得可以获得高速亮度响应。 当预先知道连续显示相同图像的帧数时，在显示模式设置寄存器中设置帧数，并且提供检测图像改变定时的功能。 这样可以实现高效的超速运行。 此外，在低温下，显示图像根据温度信息更新一次数帧。 这增强了图像的可视性。

摘要： In a display device such as a liquid crystal display, a processing for compressing a range of display data (grayscale) to a low grayscale side (a grayscale range where response is fast) except for a high grayscale side (a grayscale range where response is slow) at a predetermined compression ratio to conduct display according to response characteristic of transition between grayscales and a temperature state and a processing for increasing a light amount of a backlight to compensate for luminance change due to the compression are performed, for example, in a liquid crystal panel of TN liquid crystal. Thereby, response can be made fast even at a low temperature time.

摘要： In a display device and a display driver, when a grayscale of a display image is equal to or lower than a specific grayscale value obtained from a histogram of the display image, a display grayscale is extended with a linear function. On the other hand, when a grayscale of a display image is equal to or higher than the specific grayscale value, histogram equalization of a part higher than the specific grayscale value is performed, and the display grayscale is extended with a non-linear function obtained from the histogram equalization.
