![]() ![]() The first production flat-panel display was the Aiken tube, developed in the early 1950s and produced in limited numbers in 1958. But GE did not continue with the R&D required and never built a working flat panel at that time. The publication of their findings gave all the basics of future flat-panel TVs and monitors. The first engineering proposal for a flat-panel TV was by General Electric in 1954 as a result of its work on radar monitors. On the other hand, static flat-panel displays rely on materials whose color states are bistable, such as displays that make use of e-ink technology, and as such retain content even when power is removed. liquid-crystal displays (LCD)), and can only show an image when it has power. The former requires that pixels be periodically electronically refreshed to retain their state (e.g. For example, modern smartphone displays often use OLED panels, with capacitive touch screens.įlat-panel displays can be divided into two display device categories: volatile and static. In many cases, flat-panel displays are combined with touch screen technology, which allows the user to interact with the display in a natural manner. Most LCD screens are back-lit with color filters used to display colors. Most 2010s-era flat-panel displays use LCD or light-emitting diode (LED) technologies, sometimes combined. As of 2016, flat-panel displays have almost completely replaced CRT displays. In the 2010s, portable consumer electronics such as laptops, mobile phones, and portable cameras have used flat-panel displays since they consume less power and are lightweight. While the highest resolution for consumer-grade CRT televisions was 1080i, many flat-panel displays in the 2020s are capable of 1080p and 4K resolution. They are usually less than 10 centimetres (3.9 in) thick. It is present in consumer, medical, transportation, and industrial equipment.įlat-panel displays are thin, lightweight, provide better linearity and are capable of higher resolution than typical consumer-grade TVs from earlier eras.
