LCDLEDTFTnäytöillä

LCDLEDTFTnäytöillä refers to displays that combine Liquid Crystal Display (LCD) technology with Light Emitting Diode (LED) backlighting and Thin-Film Transistor (TFT) control. This combination has become a prevalent standard for modern screens found in televisions, computer monitors, smartphones, and tablets.

LCD technology works by passing light through a polarizing filter, a layer of liquid crystals, and another polarizing filter. The liquid crystals, when subjected to an electrical voltage controlled by TFTs, can twist or untwist, thereby controlling the amount of light that passes through. This manipulation of light creates the image. TFT technology allows for precise control of individual pixels on the screen. Each pixel has its own transistor, enabling faster refresh rates, improved contrast, and reduced image smearing compared to older LCD technologies.

LED backlighting has largely replaced older CCFL (cold cathode fluorescent lamp) backlights. LEDs are more energy-efficient, provide a wider color gamut, and allow for thinner display designs. They can also be dimmed or turned off in specific areas of the screen, leading to better contrast ratios and deeper blacks, a feature often marketed as "local dimming" or part of "LED TV" technology. The term "LCDLEDTFTnäytöillä" encapsulates this integrated approach, signifying a screen that is both technologically advanced and widely accessible for various display applications.
