Adoption of New Accounting Pronouncements |

| New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
| Adoption of New Accounting Pronouncements | Adoption of New Accounting Pronouncements New Accounting Pronouncements Adopted in Fiscal Year 2019 Effective January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, which provides guidance for lease accounting. The new guidance contained in the ASU stipulates that lessees will need to recognize a right-of-use ("ROU") asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. Treatment in the consolidated statements of income will be similar to the historical treatment of operating and capital leases. The adoption of this standard did not have a material impact on the Company's consolidated balance sheet or consolidated income statement. Disclosures are now required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. New Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The standard requires a change in the measurement approach for credit losses on financial assets measured on an amortized cost basis from an incurred loss method to an expected loss method, thereby eliminating the requirement that a credit loss be considered probable to impact the valuation of a financial asset measured on an amortized cost basis. The standard requires the measurement of expected credit losses to be based on relevant information about past events, including historical experience, current conditions, and a reasonable and supportable forecast that affects the collectability of the related financial asset. The Company will be required to adopt ASU 2016-13 as of January 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-13 on the Company’s consolidated financial statements.

| Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill represents the cost of an acquisition in excess of the fair values assigned to identifiable net assets acquired. The Company recorded Goodwill of $307.4 million as part of the HomeLink® acquisition. The carrying value of Goodwill as of December 31, 2018 and March 31, 2019 was $307.4 million. In addition to annual impairment testing, which is performed as of the first day of the fourth quarter, the Company continuously monitors for events and circumstances that could negatively impact the key assumptions in determining fair value thus resulting in the need for interim impairment testing, including long-term revenue growth projections, profitability, discount rates, recent market valuations from transactions by comparable companies, volatility in the Company's market capitalization, and general industry, market and macroeconomic conditions. No such events or circumstances in the most recently completed quarter indicated the need for interim impairment testing. The patents and intangible assets and related change in carrying values are set forth in the tables below: As of March 31, 2019:
As of December 31, 2018:
Amortization expense on patents and intangible assets was approximately $5.6 million during the three ended March 31, 2019, compared to approximately $5.7 million for the same period ended March 31, 2018, . Excluding the impact of any future acquisitions, the Company continues to estimate amortization expense for each of the years ended December 31, 2019, 2020, and 2021 to be approximately $22 million annually, approximately $21 million for 2022, and approximately $19 million for the year ended December 31, 2023.

| Investments | The Company follows the provisions of ASC 820, “Fair Value Measurements and Disclosures” for its financial assets and liabilities, and for its non-financial assets and liabilities subject to fair value measurements. ASC 820 provides a framework for measuring the fair value of assets and liabilities. This framework is intended to provide increased consistency in how fair value determinations are made under various existing accounting standards that permit, or in some cases, require estimates of fair-market value. This standard also expanded financial statement disclosure requirements about a company’s use of fair-value measurements, including the effect of such measurement on earnings. The cost of securities sold is based on the specific identification method. The Company determines the fair value of its government securities, municipal bonds, and corporate bonds by utilizing monthly valuation statements that are provided by its broker. The broker determines the investment valuation by utilizing the bid price in the market and also refers to third party sources to validate valuations, and as such are classified as Level 2 assets. The Company's certificates of deposit have remaining maturities of less than one year and are considered as Level 1 assets. These investments are carried at cost, which approximates fair value. The Company will also periodically make technology investments in certain non-consolidated third-parties for ownership interests of less than 20%. These investments do not have readily determinable fair values, and the Company has not identified any observable events that would cause adjustment of the valuation to date, and therefore these investments were held at cost at a total of $4.1 million and $3.85 million as of March 31, 2019 and December 31, 2018, respectively. These investments are classified within Long-Term Investments in the consolidated balance sheet. Assets or liabilities that have recurring fair value measurements are shown below as of March 31, 2019 and December 31, 2018: As of March 31, 2019
As of December 31, 2018

ASC 320, “Accounting for Certain Investments in Debt and Equity Securities”, as amended, provides guidance on determining when an investment is other than temporarily impaired. No investment losses were considered to be other than temporary during the periods presented. The Company has the intention and current ability to hold its debt investments until the amortized cost basis has been recovered. Fixed income securities as of March 31, 2019 have contractual maturities as follows:

| Earnings Per Share | Earnings Per Share The Company has unvested share-based payment awards with a right to receive non-forfeitable dividends, which are considered participating securities under ASC Topic 260, Earnings Per Share. The Company allocates earnings to participating securities and computes earnings per share using the two-class method. Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, net income is allocated to both common shares and participating securities based on their respective weighted average shares outstanding for the period. The following table sets forth the computation of basic and diluted net income per common share under the two-class method for the three months ended March 31, 2019 and March 31, 2018, respectively:

| Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stock-Based Compensation Plans | Stock-Based Compensation Plans As of March 31, 2019, the Company had four equity incentive plans, which include two stock option plans, a restricted stock plan and an employee stock purchase plan. Those plans and any prior material amendments thereto have previously been approved by shareholders. In February 2019, the Company's Compensation Committee and Board of Directors approved the Gentex Corporation 2019 Omnibus Incentive Plan or 2019 Omnibus Plan, subject to shareholder approval. The 2019 Omnibus Plan provides for the potential awards to: i) employees; and ii) nonemployee directors of the Company or its subsidiaries, which awards may be stock options, both incentive stock options and non-qualified stock options, appreciation rights, restricted stock, restricted stock units, performance shares awards and performance units, and other awards that are stock-based, cash-based or a combination of both. The 2019 Omnibus Plan is intended to replace the Company's shareholder approved Employee Stock Option Plan, Second Restricted Stock Plan, and Amended and Restated Non-Employee Director Stock Option Plan (the "Prior Plans"), upon shareholder approval, though first quarter 2019 grants to non-officer employees were made under the Prior Plans since the 2019 Omnibus Plan has not yet been approved by Shareholders. Any existing awards previously granted under the Prior Plans, including those made to non-officers in the first quarter of 2019, will continue to remain outstanding in accordance with their terms and be governed thereby. If, however, the 2019 Omnibus Plan is approved by the shareholders, all future awards thereafter will be made under the 2019 Omnibus Plan, including those made to officers in the first quarter of 2019. If the 2019 Omnibus Plan is not approved by shareholders, it will not be adopted and the Company will continue to operate under the Prior Plans until their expiration. Readers should refer to Note 5 of the consolidated financial statements in the Company's Annual Report on Form 10-K for the calendar year ended December 31, 2018, for additional information related to the Prior Plans. The Company recognized compensation expense for share-based payments of $4,786,794 for the three months ended March 31, 2019, and $3,901,316 for the three months ended March 31, 2018. Compensation cost for share based payment awards capitalized as part of inventory as of March 31, 2019 and March 31, 2018 was $295,973 and $258,651, respectively. Employee Stock Option Plan The Company has an employee stock option plan covering 24,000,000 shares of common stock. The purpose of the plan is to provide an opportunity to use stock options as a means of recruiting new managerial and technical personnel and as a means for retaining certain employees of the Company by allowing them to purchase shares of common stock of the Corporation and thereby having an additional incentive to contribute to the prosperity of the Company. The fair value of each option grant in the employee stock option plan was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions for the indicated periods:
1.Represents the Company’s estimated cash dividend yield over the expected term of option grant. 2.Amount is determined based on analysis of historical price volatility of the Company’s common stock. The expected volatility is based on the daily percentage change in the price of the stock over a period equal to the expected term of the option grant. 3.Represents the U.S. Treasury yield over the expected term of the option grant. 4.Represents the period of time that options granted are expected to be outstanding. Based on analysis of historical option exercise activity, the Company has determined that all employee groups exhibit similar exercise and post-vesting termination behavior. Under the employee stock option plan, the option exercise price equals the stock’s market price on the date of grant. The options vest after one to five years, and expire after five to ten years. As of March 31, 2019, there was $7,650,472 of unrecognized compensation cost related to share-based payments, which is expected to be recognized over the remaining vesting periods. Non-employee Director Stock Option Plan The Company has a non-employee director stock option plan covering 1,000,000 shares of common stock. As of March 31, 2019, there was $4,302 of unrecognized compensation cost under the non-employee director plan related to share-based payments. The Company has granted options on 483,940 shares under the non-employee director plan through March 31, 2019. Under the non-employee director plan, the option exercise price equals the stock’s market price on the date of grant. The options vest after six months, and expire after ten years. Employee Stock Purchase Plan The Company has an employee stock purchase plan covering 2,000,000 shares of common stock. Under the plan, the Company sells shares at 85% of the stock’s market price at date of purchase. Under ASC 718, the 15% discounted value is recognized as compensation expense. As of March 31, 2019, the Company has granted 1,026,404 shares under this plan. Restricted Stock Plan The Company has a restricted stock plan covering 9,000,000 shares of common stock. The purpose of the restricted stock plan is to permit grants of shares, subject to restrictions, to employees of the Company as a means of retaining and rewarding them for performance and to increase their ownership in the Company. Shares awarded under the restricted stock plan entitle the shareholder to all rights of common stock ownership except that the shares may not be sold, transferred, pledged, exchanged or otherwise disposed of during the restriction period. The restriction period is determined by the Compensation Committee, appointed by the Board of Directors, but may not exceed ten years under the terms of the plan. As of March 31, 2019, the Company had unearned stock-based compensation of $36,944,099 associated with these restricted stock grants. The unearned stock-based compensation related to these grants is being amortized to compensation expense over the applicable restriction periods. Amortization expense from restricted stock grants in the three months ended March 31, 2019 was $2,723,579, and for the three months ended March 31, 2018 was $1,643,060. 2019 Omnibus Incentive Plan The Omnibus Incentive Plan will cover 45,000,000 shares of common stock, if approved by the shareholders (thereby replacing the Prior Plans). The purpose of the 2019 Omnibus Incentive Plan is to attract and retain directors, officers, and other employees of the Company and its subsidiaries and to motivate and provide such persons incentives and rewards for performance.

| Income Taxes | Income TaxesThe effective tax rate was 16.5% in the three months ended March 31, 2019 compared to 15.6% for the same period in 2018. Generally, effective tax rates for these periods differ from statutory federal income tax rates, due to provisions for state and local income taxes, permanent tax differences, and the foreign-derived intangible income tax deduction. The increase in the effective tax rate for the three months ended March 31, 2019 compared to the same period of 2018 was primarily due to a decrease in discrete tax benefits related to stock-based compensation in the current year. |

Adoption of New Accounting Pronouncements (Policies) |
3 Months Ended |

| New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
| Adoption of New Accounting Pronouncements | New Accounting Pronouncements Adopted in Fiscal Year 2019 Effective January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, Leases, which provides guidance for lease accounting. The new guidance contained in the ASU stipulates that lessees will need to recognize a right-of-use ("ROU") asset and a lease liability for substantially all leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. Treatment in the consolidated statements of income will be similar to the historical treatment of operating and capital leases. The adoption of this standard did not have a material impact on the Company's consolidated balance sheet or consolidated income statement. Disclosures are now required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. New Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The standard requires a change in the measurement approach for credit losses on financial assets measured on an amortized cost basis from an incurred loss method to an expected loss method, thereby eliminating the requirement that a credit loss be considered probable to impact the valuation of a financial asset measured on an amortized cost basis. The standard requires the measurement of expected credit losses to be based on relevant information about past events, including historical experience, current conditions, and a reasonable and supportable forecast that affects the collectability of the related financial asset. The Company will be required to adopt ASU 2016-13 as of January 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2016-13 on the Company’s consolidated financial statements.
