Segment Reporting [Abstract]  
Segment Information SEGMENT INFORMATION
We operate in one segment: the design, development, marketing and sale of IC solutions for use in electronic display devices. We generate our revenue from two broad product markets: the Mobile market and the Home & Enterprise market. The chief operating decision maker, or CODM, is our CEO. Our CODM evaluates financial performance and allocates resources using financial information reported on a company-wide basis. The Cinema market does not contribute material revenue and is therefore being included in this one segment.
