摘要： The memory interface circuit converts an input data signal into multi-scan data signals used for a multi-scan type liquid crystal display. The memory interface circuit includes: a memory for storing one frame of the input data signal corresponding to the display panel, and a control circuit for controlling write/read operations for the memory so that the input data signal is sequentially written in the memory in a single-scan manner, and that data stored in the memory is read out as first and second multi-scan signals in a multi-scan manner. The control circuit controls timing of read operations so that a read operation for the second multi-scan signal is started a predetermined time after that for the first multi-scan signal is started, the predetermined time being equal to a delay time of a write operation of the input data corresponding to the second portion with respect to that corresponding to the first portion.

摘要： An optical semiconductor assembly including a metal stem, a hermetic glass substrate fixed to the stem, and a conductive float pad formed on the hermetic glass substrate. The first to third leads are mounted to the stem so as to be insulated from the stem and pass through the stem. An optical semiconductor element is mounted on a lead head of the third lead, and a bare chip IC is mounted on the stem. By using the float pad, screening of the optical semiconductor element is performed during assembly. After completing the assembly, the characteristics of the assembly are checked to thereby perform screening of the bare chip IC. Thus, two independent steps of screening are performed, so that improvement in yield of the completed products can be expected.
