Liquid crystal arrangements
In nematic arrangements the crystals are randomly positioned with all their long axes pointing in essentially the same direction, given by a vector known as the director. In smectic arrangements the crystals are further constrained to parallel planes; in smectic A the director is perpendicular to these planes, while in smectic C the director is at some other angle to the planes.
Compared with liquid crystal displays (LCDs), cathode-ray tubes (CRTs) suffered from several significant physical and operational disadvantages:
- Size and Weight: CRTs are inherently large, bulky, and heavy, whereas LCDs can be manufactured to be thin, flat, and lightweight.1
- Durability: CRTs are breakable, making them less robust for certain applications compared to the flat-panel design of LCDs.1
- Power Consumption: CRTs require extremely high voltages to accelerate electron beams and large currents to deflect them, while LCDs are noted for consuming very little electric power.1
While CRTs were long considered the standard for high-quality, bright images, these physical limitations drove the development of alternative technologies like the LCD.1
