liquid crystal display A Brief History of its Mark
1.1 The Dawn of LCD Technology
Liquid crystal displays (LCDs) have a history dating back to the early 20th century, when scientists first discovered the properties of liquid crystals. However, it wasn't until the 1960s that researchers began to explore their potential for use in electronic devices. In 1964, George Heilmeier and his team at RCA developed the first LCD capable of displaying images.
1.2 Early Applications and Challenges
In the following years, LCD technology was applied in various fields such as watches and calculators due to its low power consumption and thin profile. Despite these advantages, early LCD screens had limited viewing angles and were not suitable for large-scale applications like television sets.
2 The Rise of Color Displays
The development of color LCD technology marked a significant milestone in its market introduction journey. In 1972, Thomas Pearsall invented a method to create full-color images using liquid crystals with different orientations responding to polarized light filters.
3 First Generation TVs: Passive Matrix Displays
The first generation of commercial liquid crystal displays used passive matrix addressing techniques which allowed them to be manufactured more cheaply than active matrix displays but suffered from slower response times leading to blurry images.
4 Second Generation TVs: Active Matrix Displays
Active matrix addressing resolved many issues faced by passive matrix displays including faster response times resulting in clear image quality suitable for television viewing experiences.
5 Liquid Crystal Display's Market Debut
With improvements made over several decades through advancements in materials science and electronics engineering, liquid crystal display technology became commercially viable enough for mass production by major manufacturers such as Sharp Corporation who released their first LC TV set called "LC-TVT-700" on June 25th, 1990 marking an important milestone along this journey towards widespread adoption across consumer markets worldwide!
6 Technological Advancements Post-Market Debut
Since then numerous technological advancements have continued shaping this industry; one notable example is the transition from CCFL backlighting found typically used inside older models toward edge-lit LED lighting systems offering improved contrast ratios better color gamut efficiency while reducing energy usage further solidifying lcd tvs place within modern living spaces!
