Abstract: A semiconductor device includes plural electrode pads arranged in an active region of a semiconductor chip, and wiring layers provided below the plural electrode pads wherein occupation rates of wirings arranged within the regions of the electrode pads are, respectively, made uniform for every wiring layer. To this end, in a region where an occupation rate of wiring is smaller than those in other regions, a dummy wiring is provided. On the contrary, when the occupation rate of wiring is larger than in other regions, slits are formed in the wiring to control the wiring occupation rate. In the respective wirings layers, the shapes, sizes and intervals of wirings below the respective electrode pads are made similar or equal to one another.

Abstract: In conventional liquid crystal display controllers, 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 includes a drive duty selection register capable of being rewritten by a microprocessor, and a drive bias selection register. When the display is changed from the whole display on a liquid crystal display panel 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 translation: 在传统的液晶显示控制器中，显示器在待机状态下被降低，但是液晶显示器的占空比不改变，即使扫描不产生显示器的行的公共电极，并且电力的消耗 在待机状态下没有降低到足够的程度。 液晶显示控制器包括能够由微处理器重写的驱动占空比选择寄存器和驱动偏置选择寄存器。 当显示器从液晶显示面板上的整个显示器改变到仅部分行上的部分显示时，驱动占空比选择寄存器和驱动偏置选择寄存器的预设值被改变，使得显示器 在低负载驱动下以低电压选择性地在液晶显示面板的一部分上产生。
