1973 - Sharp produced the first pocket-sized LCD calculator, the Sharp EL-805, which also combined the display and electronics on a single glass substrate, known as 'COS'. More details of these developments are given below.

But as a result of untiring efforts by Sharp R&D staff, the world's first LCD application was born. In 1973, Sharp released the first ever calculator with an LCD display.

But through the unrelenting efforts of Sharp's engineers, the company succeeded in 1973 in introducing a calculator with the world's first practical LCD unit. The electronic calculator that incorporated this breakthrough, the EL-805, was a COS type unit in which the LCD, CMOS-LSI circuitry and wiring were all accommodated on a single glass panel.

The EL-805 COS-type pocket calculator introduced in 1973 was the first product on the market to use LCDs. In December 2005, the EL-805 was one of the calculators recognized with a prestigious IEEE Milestone *1 from the IEEE *2.

The Sharp EL-805 of 1973 was the first pocket-sized calculator with a Liquid Crystal display (LCD) and used Sharp's 'COS' (variously 'Crystal on Substrate' or 'Calculator on Substrate') technology, as illustrated in the photographs below.

It was on May 15, 1973 that Sharp released the EL-805 LCD calculator, starting a revolution in electronics. Until then, calculators used fluorescent character display tubes or light-emitting diodes. Using LCD for the number display meant that power consumption was cut dramatically - to a mere 1/100th of previous calculators.

Aug 4, 2019 · The Sharp QT-8D, also known as the "micro Compet", has the distinction of being recognized as the first electronic calculator to have its calculating logic implemented entirely with MOS (Metal-Oxide Semiconductor) large-scale integrated circuitry.

Sharp's first calculator using the yellow-screen FEM-type display was the EL-8020 and its memory counterpart, EL-8120. These models first appeared in early 1976, but had been preceded by Casio's Pocket LC, which was released in late 1975.

Sharp EL-805, released May 15, 1973, this is the first Sharp LCD calculator and one of the first LCD calculators ever. The first is the Lloyd's Accumatic 100, produced by Rockwell in 1972, according to Vintage Calculators .

The Sharp EL-805, introduced in 1973, was the first pocket-sized LCD calculator. This is a featured calculator . The Sharp EL-805 also pioneered the integration of the LCD display and electronics on a single glass circuit board.
