HDR HDR Display Technology & Hardware 1 — Questions and Answers
Question 1: What is the minimum peak luminance requirement for a display to be certified as HDR10 compliant?
- 400 nits (Correct answer)
- 1000 nits
- 600 nits
- 2000 nits
Correct answer: 400 nits
HDR10 requires a minimum peak luminance of 400 nits, though 1000 nits is considered optimal for full HDR performance.
Question 2: Which display technology uses per-pixel light control to achieve the deepest blacks in HDR content?
- Full-array local dimming LCD
- OLED (Correct answer)
- Mini-LED
- Edge-lit LCD
Correct answer: OLED
OLED displays achieve perfect blacks because each pixel emits its own light and can be turned off completely, providing infinite contrast ratios.
Question 3: What does FALD stand for in the context of HDR display hardware?
- Full Array Local Dimming (Correct answer)
- Fixed Adaptive Light Display
- Full Aperture Lens Diffusion
- Frame Accurate Light Delivery
Correct answer: Full Array Local Dimming
FALD stands for Full Array Local Dimming, a backlighting technique that divides the backlight into zones for improved HDR contrast.
Question 4: Which color volume metric measures a display's ability to reproduce high brightness AND wide color gamut simultaneously?
- Color Rendering Index
- DCI-P3 coverage
- Rec. 2020 coverage
- Color Light Output (Correct answer)
Correct answer: Color Light Output
Color Light Output (CLO) measures the intersection of a display's brightness capability and color gamut at every luminance level.
Question 5: What is the primary advantage of Mini-LED backlighting over conventional LED LCD for HDR displays?
- Lower cost manufacturing
- Greater number of dimming zones for improved local contrast (Correct answer)
- Higher refresh rates
- Reduced panel thickness
Correct answer: Greater number of dimming zones for improved local contrast
Mini-LED backlighting uses thousands of tiny LEDs arranged in many more dimming zones than conventional LEDs, significantly improving local contrast for HDR.
Question 6: Which HDR display certification program is managed by the Consumer Technology Association (CTA)?
- Dolby Vision
- HDR10+
- DisplayHDR (Correct answer)
- Ultra HD Premium
Correct answer: DisplayHDR
DisplayHDR is the open performance specification and testing methodology for HDR displays, managed by VESA and defined in CTA standards.
