57‐3: Characterizing Image Retention for HDR OLED Displays

Abstract

A burn‐in measurement technique was realized and tested for both standard and high dynamic range (HDR) organic light emitting diode (OLED) displays. The proposed measurement targets analyze wide color gamut, non‐RGB primary, and HDR displays. The system was implemented in commercial OLED displays to validate the proposed measurement system.

51‐3: Color Shifting in High Dynamic Range OLED Displays

“…After 1200 hours of aging detailed in [1], two televisions, Sony OLED XBR55A8F and LG OLED55B8 were received. These displays were aged in SDR mode, with the burn-in target shown in Figure 1a.…”

“…This becomes a nuisance when taking measurements on the displays. To counter this, the same setup from [1] was utilized. Through the RS232 serial port on the TVs, we can digitally mimic a button press every minute so that the TVs never enter screen saver mode.…”

“…The work presented in [1], detailed an in-depth controlled aging experiment of sixteen 55-inch OLED panels. These displays were operated at maximum brightness with panel protection measures turned off.…”

“…In this work, we build upon the work presented in [1] and [5] by building an HDR testbench for preaged OLED panels. We will demonstrate the color and luminance shifting changes in the aged display in HDR viewing mode.…”

P‐46: RGB Pixel Aging in OLED Displays

“…While these papers primarily measured the aging effects in white pixels, this work looks to isolate and study the aging effects of the single-color LEDs that make up the RGB pixel. The aging approach and measurement methods were based on the foundation set in [8] and [9] and has been applied to several sets of OLED televisions from different displays on the market.…”
