Abstract: A data bus structure, a driver therewith, and a display with a driver capable of low power consumption are provided herewith. In the proposed structure, data lines of the data bus corresponding to a plurality of output channels are divided by alternatively inserting isolating elements. By controlling these isolating elements, current will be alternatively isolated from a portion of the bus and power consumption is significantly reduced. In the proposed structure, different function and settings can be determined in advance in consideration of where data is taken into the bus line.

Abstract: Disclosed is a package for housing semiconductor elements, which comprises an insulating substrate having in the interior thereof a cavity for attaching and housing semiconductor elements and a lid member covering said cavity, wherein the insulating substrate is composed of a mullite sintered body comprising 70 to 95% by weight of mullite and 5 to 30% by weight, as the total content, of silica (SiO.sub.2) and at least one member selected from the group consisting of magnesia (MgO) and calcia (CaO), and SiO.sub.2, MgO and CaO are present in the following composition expressed by % by weight based on the three components:100>SiO.sub.2 .gtoreq.60,40.gtoreq.MgO.gtoreq.O and40.gtoreq.CaO.gtoreq.O.
