    • The deterioration (darkness) of image quality due to a reduction in the brightness of a single color as a result of the conversion from RGB pixels to RGBW pixels is prevented and a reduction in the power is achieved. A processing portion for conversion from RGB to RGBW 106 is formed of a W generating circuit 201, which is the same as in the prior art, a sub-pixel rendering circuit 202, a W intensity calculating portion 203 which transmits a W intensity setting value 205 to a W generating circuit 201, and a low power backlight control circuit 204 which expands data on the basis of the RGBW pixels generated by the sub-pixel rendering portion 202 and lowers the backlight in accordance with the amount by which the data is expanded. The inputted RGB data is used as the RGBW data with the W intensity calculated by the W intensity calculating portion 203. A backlight control signal is generated in accordance with the amount of data expansion in the sub-pixel rendering portion 202.
    • 由于由RGB像素转换为RGBW像素而导致的单色亮度降低导致的图像质量的恶化(黑暗)被防止并且能够实现功率的降低。 用于从RGB转换为RGBW 106的处理部分由与现有技术相同的W发生电路201形成为子像素渲染电路202,W强度计算部分203,其发送W强度设定值 205到W发生电路201,以及低功率背光控制电路204,其根据由子像素渲染部分202生成的RGBW像素扩展数据,并根据数据扩展的量降低背光 。 输入的RGB数据被用作由W强度计算部分203计算的W强度的RGBW数据。根据子像素渲染部分202中的数据扩展量来生成背光控制信号。

    • 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.
    • 斜盘式压缩机具有旋转轴,用于与轴一起旋转的倾斜斜盘和连接到斜盘的多个活塞。 每个活塞在其两端限定一对工作室。 活塞在与旋转斜盘的旋转同时进行摆动运动的同时往复运动,将流体吸入工作室进行压缩。 旋转斜盘通过支撑单元安装在轴上,支撑单元用于选择性地改变斜盘的倾斜度并沿着轴移动斜盘的旋转中心。 流体从吸入通道通过旋转斜盘周围引入到邻近工作室形成的吸入室。 旁路通道形成为在旁路旋转斜盘时将抽吸通道与轴的一侧上的吸入室直接连通。 当斜盘的倾斜减小并且其旋转中心位置移动时,使得在轴的一侧的工作室中基本上没有完成流体的压缩以减小压缩机的位移,则流体在 一侧抽吸室通过旁路通道,响应于流体流向另一侧工作室,以润滑和冷却用于轴的滑动部件。

    • A display drive circuit of the invention has: an initial-color-gamut-apex-coordinate-storing unit capable of storing initial color gamut apex coordinates; a user-target-color-gamut-apex-coordinate-storing unit capable of storing user target color gamut apex coordinates; a saturation-expansion-coefficient-deciding unit for deciding expansion coefficients of saturation data based on the initial and user target color gamut apex coordinates; and an expansion unit for expanding saturations of display data based on the saturation expansion coefficients. The expansion coefficients of saturation data are decided based on the initial and user target color gamut apex coordinates, and saturations of display data are expanded according to the expansion coefficients. Thus, the degree of expanding the saturations can be controlled for each color gamut or each of R, G and B color properties of an LC display panel.
