The TI ViewScreen panel connects with a cable to the Texas Instruments Graphing calculators. Placing the panel on the overhead projector enlarges the image of the handheld screen so that each student can follow along. Don't miss the US Patent Application U.S. Pat. No. 5,168,294 with the title “Display demonstration system for providing enlarged projected image of calculator display” filed already in September 27, 1991.
The TI ViewScreen 92 was introduced in 1995 with first deliveries in Spring 1996 and connects to the TI-92. It was delivered either as the ViewScreen panel package with the power supply and a carrying case or as part of the ViewScreen system including the Graphing calculator.
In 2008 four different ViewScreen panels were available for TI's Graphing calculators:
|• Panel 1:
TI-73 VSC, TI-73 Explorer VSC,
TI-82 VSC, TI-83 VSC,
TI-83 Plus VSC, TI-83 Plus Silver Edition VSC, TI-84 Plus VSC,

this TI ViewScreen 92 with
Date code 0396 manufactured in March 1996 by
Texas Instruments in their Rieti, Italy, facility
reveals no surprises and looks similar to the TI ViewScreen 82 introduced in
October 1993 but changed the display drivers to accommodate the larger pixel
count of the TI-92 compared to the TI-82. A large, transmissive LCD panel is connected to
T6A39 and T6A40 display driver known already
from the TI-81 introduced in 1992. The reminder
of the electronics resembles the receivers of the signals from the connected ViewScreen Calculator, contrast adjustment of the screen and power supply for
The arrangement of three Toshiba T6A39 column drivers and two T6A40 row drivers found in the TI ViewScreen 92 is not really obvious from the very complex layout of the printed circuit board (PCB).
The Presentation Link Adapter connects the student versions of the TI-89 Titanium family to the ViewScreen panel using the calculator's USB port.
With the phase out of the overhead projectors from the daily life, Texas Instruments developed with the TI-Presenter a perfect replacement for the ViewScreen panels based on modern video technology.
