220-1101 Question 183
Single answerMini light-emitting diode (Mini-LED)A graphics designer asks a technician to recommend a new laptop display for editing HDR photos and videos on the road. The designer wants deeper blacks and better contrast than a standard LED-backlit LCD, but does not want the higher cost and possible burn-in concerns associated with OLED. Which display technology best meets these requirements?
- A
Mini-LED display
- B
TN LCD display
- C
Plasma display
- D
E-ink display
Show answer and explanation
Correct answer: A
Explanation
Mini-LED is the best answer because it directly matches the customer's stated needs: better contrast and darker black levels than a conventional LED-backlit LCD, without choosing OLED. Mini-LED is still an LCD display, but it improves the backlight system by using many smaller LEDs, which allows finer local dimming control. This makes it well suited for HDR content creation and media consumption. In A+ Core 1 terms, technicians should recognize display technologies and recommend hardware based on user requirements, cost, and trade-offs. Industry documentation from major display manufacturers consistently describes Mini-LED as an advancement of LCD backlighting that improves brightness and contrast, especially for HDR workloads, while OLED remains the technology more commonly associated with per-pixel illumination and burn-in concerns.
- A. Correct.
Correct. Mini-LED uses a very large number of tiny LEDs as the LCD backlight, enabling more local dimming zones than traditional LED-backlit LCDs. In practice, this improves contrast, black levels, and HDR performance while still remaining an LCD-based technology. It is commonly positioned as an alternative for users who want better image quality than standard LED LCDs without moving to OLED.
- B. Incorrect.
Incorrect. TN LCD panels are typically chosen for lower cost and fast response times, but they generally have weaker color reproduction and viewing angles than IPS-class panels and do not address the designer's goal of significantly improved contrast and black levels. TN is not a premium HDR-focused answer to this scenario.
- C. Incorrect.
Incorrect. Plasma is not an appropriate modern laptop display technology. It was used in some larger televisions but is obsolete in this context and was never a practical choice for current portable systems. A technician selecting this would be ignoring real-world product availability and form-factor limitations.
- D. Incorrect.
Incorrect. E-ink is designed for extremely low-power, paper-like reading displays, not color-accurate HDR photo and video editing. It does not fit the designer's need for rich multimedia performance, high contrast in moving video content, or standard laptop creative-work use.
