Some LCD panels have native fiber-optic inputs in addition to DVI and HDMI. [156] Many LCD monitors are powered by a 12 V power supply, and if built into a computer can be powered by its 12 V power supply. Can be made with very narrow frame borders, allowing multiple LCD screens to be arrayed side by side to make up what looks like one big screen.
By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add ...
For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well.

The calculator took advantage of an effect of pulsed LED operation where very brief pulses of light are perceived as brighter than a longer pulse of light with the same time-integral of intensity. A keyboard matrix circuit has a very similar arrangement as a multiplexed display, and has many of the same advantages.
Having supplanted passive-matrix LCDs in general use, in common vernacular, an active-matrix LCD is also simply referred to as a LCD. As of 2025, the term "AMLCD" is uncommon as a matter of technical jargon ; instead, due to their ubiquity, different types of active-matrix liquid crystal displays are usually specified — TFT LCD , IPS LCD ...
