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, 2016. The Condensed Consolidated Balance Sheet at December 31, 2016 is derived from the December 31, 2016 audited financial statements. There have been no material changes in our significant accounting policies during the six months ended June 30, 2017 from the significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016. Recent Accounting Pronouncements: In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-07, Compensation – Retirement Benefits (Topic 715). ASU 2017-07 improves the presentation of net periodic pension cost and net periodic postretirement benefit cost. Public business entities should apply the amendments in ASU 2017-07 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years (i.e., January 1, 2018), 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. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350). ASU 2017-04 simplifies the test for goodwill impairment. Public business entities should apply the amendments in ASU 2017-04 for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years (i.e., January 1, 2020), 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. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230). ASU 2016-18 modifies the presentation of Restricted Cash on the Statement of Cash Flows. Public business entities should apply the amendments in ASU 2016-18 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years (i.e., January 1, 2018), 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. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019), early application is permitted. The Company is in the process of evaluating this pronouncement but has not yet determined the effect of the adoption of this standard on the Company’s consolidated financial position and results of operations. In August 2015, the FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) by one year. As a result, the ASU is now effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which for the Company is the first quarter of 2018. Earlier application is permitted for fiscal years beginning after December 15, 2016, including interim reporting periods within those years, which for the Company is the first quarter of 2017. The Company is in the process of evaluating this pronouncement but does not expect the adoption of this standard to have a material effect 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.
