Question 340 - 220-1101 discussion

A graphic designer wants to purchase a laptop that provides the most accurate color spectrum available when viewed from as many different angles as possible. Which is the following display types would best meet the graphic designer's requirements?

LCD

Plasma

OLED

VGA

Suggested answer: C

Explanation:

Explore The correct answer is C. OLED.

OLED stands for Organic Light-Emitting Diode, and it is a type of display technology that uses organic compounds to create light and color. Unlike LCD (Liquid Crystal Display) or Plasma displays, OLED does not require a backlight or a filter to produce images. This means that OLED can offer higher contrast, wider color gamut, and better viewing angles than other display types.

LCD displays use liquid crystals that are sandwiched between two polarizing filters and illuminated by a backlight. The liquid crystals can change their orientation and block or allow light to pass through the filters. LCD displays can have different panel types, such as IPS (In-Plane Switching), VA (Vertical Alignment), or TN (Twisted Nematic), which affect the color accuracy, response time, and viewing angles of the display.

Plasma displays use gas-filled cells that are electrically charged to create plasma, which emits ultraviolet light. The ultraviolet light then excites phosphors that emit visible light and color. Plasma displays can produce deep blacks and high contrast, but they are also prone to image retention, screen burn-in, and high power consumption.

VGA stands for Video Graphics Array, and it is not a display type but a video interface standard that was introduced in 1987. VGA can transmit analog signals from a computer to a monitor, but it has low resolution and limited color depth compared to modern digital standards such as HDMI or DisplayPort.

Therefore, OLED is the best display type for graphic designers who want the most accurate color spectrum and the widest viewing angles. OLED displays can also be thinner and lighter than LCD or Plasma displays, which makes them ideal for laptops. However, OLED displays are also more expensive and less durable than other display types, and they may suffer from image retention or burn-in over time.
