The flicker of a CRT monitor can cause various symptoms in those sensitive to it such as eye strain, headaches [9] in migraine sufferers, and seizures in epileptics. [10]As the flicker is most clearly seen at the edge of our vision there is no obvious risk in using a CRT, but prolonged use can cause a sort of retinal shock where the flickering is seen even when looking away from the monitor.
From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. Since 2010, the typical display aspect ratio of both televisions and computer monitors changed from 4:3 to 16:9 [ 1 ]
The Connection Machine, a 65 536-processor parallel computer designed in the mid-1980s, was a black cube with one side covered with a grid of red blinkenlights; the sales demo had them evolving Conway's Game of Life patterns. [1] The two CPU load monitors on the front of BeBoxes were also called "blinkenlights". [3]

The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
In diffused lens LEDs, this circuit is visible as a small black dot. Most flashing LEDs emit light of one color, but more sophisticated devices can flash between multiple colors and even fade through a color sequence using RGB color mixing. Flashing SMD LEDs in the 0805 and other size formats have been available since early 2019. Flickering
In software design, the blinking twelve problem [1] is when features in software or computer systems are rendered unusable to most users by the complexity of the interface to them. The usage emanates from the 'clock' feature provided on many VCRs manufactured in the late 1980s or early 1990s. The clock could be set by using a combination of ...
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
