LCD Uhr Texas Instruments mit pseudoanalogem Display

Among the technology “firsts” for this watch were: 1) Use of low-voltage liquid-crystal material for a multiplexed LCD; 2) Use of a lithium-manganese dioxide cell; 3) Use of an I2L (integrated injection logic) chip to drive the LCD; 4) Use of only 26 contacts for 120 display elements using two-way multiplexing. The watch was manufactured until 1981 when TI closed out all watch activity.

It is part of the Smithsonian collection and of the Dt. Museum in Munich.
