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. The CODM assesses performance for the operating segment and decides how to allocate resources based on net income (loss) that is also reported on the condensed consolidated statements of operations.
The CODM regularly reviews the condensed consolidated statements of operations and a disaggregation of operating expenses, of which the significant expenses are related to employee base compensation. Employee base compensation included in operating expenses was $13,285 and $16,373 for the nine months ending September 30, 2025 and 2024, respectively. Other segment items include outside services, depreciation and amortization, non-recurring engineering expense, accounting and legal fees, and other expenses. Other segment items included in operating expenses was $19,336 and $25,813 for the nine months ending September 30, 2025 and 2024, respectively. The CODM does not regularly review segment assets to make decisions regarding the allocation of resources, and as such the Company has not included assets.
