Instructors: Charles Poynton, independent researcher, and Dale Stolitzka, Samsung Display America Lab
Level: Advanced
Duration: 4 Hours
Course Time: 
     New York: 5 October 2021, 10:00 - 15:00
     Paris: 5 October 2021, 16:00 - 21:00
     Tokyo: 5 October 2021, 23:00 - 04:00

Course Requirement: Participants should be very familiar with colour science, and familiar with display technology. A certain level of confidence in physics;optoelectronics is introduced as needed.

Benefits:
Attendees will be able to:

• Understand where and how digital-to-analog conversion takes place.
• Identify where display nonlinearities are introduced and compensated.
• Identify sources of display non-additivity.
• Chart development progress of active matrix displays.
• Seek future display technology directions for optimized color perception.

Course Description
This course reviews the physics, electronics, and optics that influence linearity and additivity of modern displays. Modern displays exhibit near-additivity with respect to the relationship between signal input and optical output; however, the majority of display transducers are nonlinear and nonadditive. Understanding the sources of display nonlinearity and nonadditivity is important to use displays in demanding applications, and to calibrate displays. The course details the LCD V·T function (“S-curve”) and LCDs’ ubiquitous hybrid (“resistor-ladder”) DAC and explains LCD inter-pixel nonlinearities. LMCL/dual-layer LCD displays is explained, as are OLED structure, RGB OLED, WOLED (RGBW/RGBAMOLED), and their drive electronics. The course concludes with an examination of QD (quantum dot) displays such as the QD Display, and the implications for brightness, power consumption, and accuracy are discussed.

Intended Audience: The course will be most useful to applied color/imaging scientists involved with color engineering for modern electronic displays who seek to acquire knowledge of the physics, optics, and electronics of modern displays that are relevant to color performance.

Charles Poynton is an image and color scientist specializing in the physics, mathematics, and engineering of digital color imaging systems, including HD/HDTV/UHD/4K/8K, and D-cinema, high dynamic range (HDR), and wide colour gamut (WCG) systems. He does technology forecasting, systems modelling, algorithm development, video signal processing architecture, and color characterization and calibration. He is the author of Digital Video and HD Algorithms and Interfaces and earned his PhD at Simon Fraser University (2018).

Dale Stolitzka is principal engineer at the Samsung Display America Lab in San Jose, CA, and a champion of HDR technology. He leads display standardization and a Vision Lab. He leads or contributes to standards in HDR, visual perception, and display compression evaluation. He chairs the MIPI Display Working Group and the VESA Compression Task Group. He holds a bachelor in applied physics and a master in materials science, both from Cornell University.
