They aren't as crisp or fast as active-matrix (TFT) displays, however they're a lot cheaper to produce. HPA was used some years ago in entry level notebooks, but now it's practically disappeared as TFTs are less expensive. LCD redirects here. ...

HPA features many unique courses and activities (marine science field studies, sea turtle research, scuba certification, and more) that make use of Hawaii's geographical setting and give students a strong sense of Hawaii and its culture.
Each year, HPA graduates are some of the most selective universities in the United States, including Stanford, Yale, MIT, Cornell, Wellesley, and more, as well as public universities on the U.S. mainland and international colleges.
HPA provides a variety of software, including the Microsoft Office Suite, graphic arts, browsers, and e-mail, and digital media classes are available to students on both campuses.
Major saltwater activities requiring an HPA include, but are not limited to: construction of bulkheads, fills, boat launches, piers, dry docks, artificial reefs, dock floats, and marinas; placement of utility lines; pile driving; and dredging.
JARPA is used to apply for an HPA and also for Water Quality Certifications or Modifications from the Department of Ecology, Aquatic Resource Use Authorizations from the Department of Natural Resources, Army Corps of Engineers permits, and Shoreline Management Act Permits from participating local city or county agencies.
HPA applications are assigned to a Department of Fish and Wildlife Area Habitat Biologist.
