Performance Comparison between Mini-LED Backlit LCD and OLED Display for 15.6-Inch Notebook Computers

We evaluated and compared the performance of a 15.6-inch mini-LED backlit LCD (mLCD) with a commercial OLED (organic light-emitting diode) panel. Both displays exhibited outstanding properties, but the mLCD had advantages in peak brightness, gamma curve, luminance uniformity at low gray scales, colo...

Summary:We evaluated and compared the performance of a 15.6-inch mini-LED backlit LCD (mLCD) with a commercial OLED (organic light-emitting diode) panel. Both displays exhibited outstanding properties, but the mLCD had advantages in peak brightness, gamma curve, luminance uniformity at low gray scales, color volume, power consumption, and ambient contrast ratio. In comparison with previous measurement methods, our color measurement adopted the reference method recently recommended by the International Committee for Display Metrology (ICDM). The LMK imaging photometer with a high-resolution CMOS sensor was employed to characterize the halo effect and reconstruct the real luminance profiles based on the non-ideal luminance profile of the OLED display. We also proposed a novel strategy to measure the point spread function of the backlight module.
