The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 40 character lines.
LCD Smartie is open-source software for Microsoft Windows which allows a character LCD to be used as an auxiliary display device for a PC. Supported devices include displays based on the Hitachi HD44780 LCD controller , the Matrix Orbital Serial/USB LCD, and Palm OS devices (when used in conjunction with PalmOrb).
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.

NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing large-screen LCDs having acceptable visual performance for flat-panel computer monitors and television screens. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD ...
The documentation for the notable example of a display driver IC given in this article, the Hitachi HD44780 LCD controller, calls it a "dot-matrix liquid crystal display controller and driver LSI". I assume that LSI means large scale integration, i.e., a type of integrated circuit.
HD44780 is not the only character LCD drivers, Samsung KS0066 and EPSON SED1278 are also popular compatible alternatives. Pedantically incorrect is incorrect. All academic sources, I have listed 3, and most of the external links provided specifically calls it the Hitachi HD44780 driver and not the HD44780 modules. So the renaming was correct.
No practical application of this concept for projection purposes is known. However, a similar concept was used for print heads without an LCD. The first experiments with a direct-driven, transmissive matrix-addressed LCD using a converted slide projector by Peter J. Wild working at Brown Boveri Research in Switzerland were
