Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 – Basis of Presentation As used in this report, “Trans-Lux,” the “Company,” “we,” “us,” and “our” refer to Trans-Lux Corporation and its subsidiaries. Financial information included herein is unaudited, however, such information reflects all adjustments (of a normal and recurring nature), which are, in the opinion of management, necessary for the fair presentation of the Condensed Consolidated Financial Statements for the interim periods. The results for the interim periods are not necessarily indicative of the results to be expected for the full year. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with rule 10-01 of Regulation S-X promulgated by the Securities and Exchange Commission (the “SEC”) and therefore do not include all information and footnote disclosures required under accounting principles generally accepted in the United States of America (“GAAP”). The Condensed Consolidated Financial Statements included herein should be read in conjunction with the Consolidated Financial Statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The Condensed Consolidated Balance Sheet at December 31, 2015 is derived from the December 31, 2015 audited financial statements. There have been no material changes in our significant accounting policies during the nine months ended September 30, 2016 from the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2015. Recent Accounting Pronouncements: In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-09, Compensation-Stock Compensation (Topic 718). ASU 2016-09 simplifies the recording and reporting of stock based compensation. Public business entities should apply the amendments in ASU 2016-09 for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years (i.e., January 1, 2017), early application is permitted. The Company has not yet determined the effect of the adoption of this standard on the Company’s consolidated financial position and results of operations. Reclassifications: Certain reclassifications of prior years’ amounts have been made to conform to the current year’s presentation.
