CUSIP No. 007422306 5 Schedule 13D Page 4 of 7

Item 1. Security and Issuer.

This Amendment No. 20 to Schedule 13D relates to the common stock, $0.001 par value (the “Common Stock”), of Advance Display Technologies, Inc. (the “Issuer”), whose principal place of business is located at 42230 Zevo Drive, Temecula, California 92590.

Item 2. Identity and Background.

The persons filing this Schedule 13D (collectively, the “Reporting Persons”) are:

a. Lawrence F. DeGeorge, an individual, whose address is 140 Intracoastal Pointe Drive, Suite 410, Jupiter, Florida 33477.  Mr. DeGeorge is the Chief Executive Officer of LPL Group, Inc., LPL Investment Group, Inc., LPL Management Group, Inc. and DeGeorge Holdings Ltd.  The principal office of each of these companies is 140 Intracoastal Pointe Drive, Suite 410, Jupiter, Florida 33477, and their principal business is investment management.  Mr. DeGeorge is a citizen of the United States of America.

b. DeGeorge Holdings Three LLC (“DH3”) is  Delaware limited liability company, whose address is 140 Intracoastal Pointe Drive, Suite 410, Jupiter, Florida 33477.  DH3 is an affiliate of Mr. DeGeorge.  The principal business of DH3 is investment management.

During the last five years, none of the Reporting Persons have been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors).  During the last five years, none of the Reporting Persons have been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction making such Reporting Person subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

See Item 4.

Item 4. Purpose of Transaction.

As previously disclosed, the Issuer and DH3 entered into a Senior Secured Revolving Credit Agreement, dated November 6, 2008 (the “Agreement”), which was subsequently amended on June 15, 2009 (the “Amendment”).  The Agreement was ratified and approved by the Issuer’s shareholders on November 5, 2008.  Under the amended Agreement, DH3 agreed to make available to the Issuer $15,000,000 in revolving credit with a maturity date of December 31, 2010; provided, however, that all amounts owed would become immediately due and owing upon an Event of Default, including but not limited to the insolvency of the Issuer.  The Issuer’s obligations under the Agreement, as amended, are secured by substantially all of the Issuer’s tangible and intangible assets (the “Collateral”). In addition, pursuant to the Agreement, the Issuer executed a promissory note (the “Note”) in favor of DH3, which is convertible upon its terms and the terms of the Agreement into shares of Series D Preferred Stock at a rate of $0.084per common share equivalent.

In May 2010, the Issuer determined that, in addition to the impending risk that it would not meet the Sales Condition by July 1, 2010, its continuing solvency was dependent on the extension of additional credit under the Agreement, which extension DH3 was not obligated to make.  In light of the increasing risk that DH3 would declare an Event of Default under the Agreement, on May 17, 2010, the Issuer and DH3 jointly engaged an independent appraisal firm to determine the fair market value of the Issuer’s collateral under the Agreement (the “Appraisal”).

CUSIP No. 007422306 5 Schedule 13D Page 5 of 7

On June 23, 2010, the Appraisal was delivered, estimating the Issuer’s total value at approximately $7.6 million, substantially less than the approximately $14.2 million borrowed to date under the Agreement.

On June 28, 2010, DH3 notified the Issuer of its intent to exercise its foreclosure rights under the Agreement on the grounds that there was an Event of Default under the Agreement because the Issuer was insolvent.  Also on June 28, 2010, the Issuer and DH3 executed an Agreement to Accept Collateral in Partial Satisfaction of Obligations (the “Foreclosure Agreement”), by which the Issuer consented to a strict foreclosure by DH3 on the Collateral in accordance with the provisions of Section 4-9-602(a) of the Colorado Uniform Commercial Code and other applicable law (the “Foreclosure”).  Pursuant to the Foreclosure Agreement, the Issuer transferred the Collateral to ADTI Media, LLC, a Delaware limited liability company and wholly-owned subsidiary of DH3 (“ADTI Media”).  Upon this transfer, the Issuer’s obligations to DH3 under the Agreement were discharged in the amount of $8.8 million, and the total amount outstanding under the Agreement was decreased to $6,662,869, which is convertible under the Agreement.

The foregoing is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the actual text of the documents.  The Agreement and the Amendment were attached as exhibits to the Issuer’s Forms 8-K filed November 13, 2008, and June 19, 2009, respectively.  The Foreclosure Agreement was attached as an exhibit to the Issuer’s Form 8-K filed July 2, 2010.

Item 5. Interest in Securities of the Issuer.

a. As of the date of the filing of this Schedule 13D, Mr. DeGeorge is deemed to beneficially own 222,079,187 shares of Common Stock of the Issuer.  Mr. DeGeorge’s beneficial ownership represents 90% of the issued and outstanding Common Stock of the Issuer, assuming (i) conversion by DH3 of the Note into shares of Series D Preferred Stock and subsequent conversion of the resulting Series D Preferred Stock into shares of Common Stock, (ii) conversion by DH3 of Warrants convertible into shares of Series D Preferred Stock, which are in turn convertible on a one-to-one basis into shares of Common Stock, and (iii) conversion by Mr. DeGeorge of his own shares of Series D Preferred Stock into shares of Common Stock.

b. Assuming full conversion as discussed above, Mr. DeGeorge would have the sole power to vote and has sole dispositive rights with regard to 141,948,756shares of Common Stock, and shared power to vote and shared dispositive rights with regard to 80,130,431 shares of Common Stock held by DH3, for total voting and dispositive power of 222,079,187 shares of Common Stock.

c. See Item 4.

d. Not applicable.

e. Not applicable.

Except as described in Item 4, none of the Reporting Persons have effected any additional transactions with respect to the Common Stock of the Issuer during the past 60 days.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

See Item 4.

Item 7. Material to Be Filed as Exhibits.
