The revolution in LCD display technology was marked by several groundbreaking advancements. One of the most significant was the transition from passive - matrix to active - matrix technology, which was the core of the TFT - LCD development. Active - matrix technology, with its individual transistors for each pixel, brought about a quantum leap in display performance. It eliminated the problem of ghosting and image retention that was common in passive - matrix LCDs, providing a much clearer and more stable image.
Another revolutionary aspect was the improvement in backlighting technology. Initially, CCFL (Cold - Cathode Fluorescent Lamp) backlights were used in LCDs. However, they had limitations such as high power consumption, large size, and a relatively short lifespan. The introduction of LED (Light - Emitting Diode) backlights was a game - changer. LED backlights consumed less power, were thinner, and had a longer lifespan. They also offered better color accuracy and contrast ratios, especially with the development of local dimming technology, which could control the brightness of different regions of the screen independently, enhancing the black levels and overall image quality.
In addition, the development of high - refresh - rate LCDs revolutionized the gaming and fast - motion video industries. High - refresh - rate displays, starting from 120Hz and going up to 360Hz or even higher, reduced motion blur and provided a smoother visual experience. This was a significant advantage for gamers, as it allowed for more precise aiming and a more immersive gaming experience.
