An analysis of the prosecution and family history of U.S. Patent 7,557,788 B1 ("the '788 patent") reveals the following details regarding its term, related applications, and expiration.

Patent Term Adjustments (PTA) and Extensions (PTE):
There is no record of any Patent Term Adjustment (PTA) or Patent Term Extension (PTE) for the '788 patent. PTA is typically granted to compensate for delays caused by the U.S. Patent and Trademark Office (USPTO) during the examination process. The absence of PTA suggests the application's prosecution proceeded without significant administrative delays attributable to the USPTO.

Application History and Family Members:
The '788 patent is a continuation of an earlier application, which establishes its relationship to a broader patent family.

• Continuation Application: The application for the '788 patent (Ser. No. 11/743,014), filed on May 1, 2007, is a continuation of U.S. patent application Ser. No. 10/746,333, which was filed on December 23, 2003.
• Parent Patent: The parent application (Ser. No. 10/746,333) matured into U.S. Patent No. 7,233,305 B1, also titled "Gamma reference voltage generator."
• Provisional Application: The parent application, in turn, claims priority from U.S. Provisional Application Ser. No. 60/477,680, filed on June 11, 2003.

The '788 patent does not have any divisional applications.

Projected Expiration Date:
The term of a U.S. patent is generally 20 years from the filing date of the earliest U.S. or international (PCT) application to which priority is claimed (excluding provisional applications). For the '788 patent, the relevant priority date is the filing date of the parent application (Ser. No. 10/746,333), which is December 23, 2003.

Therefore, the projected expiration date for US 7,557,788 B1 was December 23, 2023. According to available records, the patent is now expired.
