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

Abstract

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.

“…Mini-LEDs have been increasingly used in advanced tablets and notebooks. The systematic comparison between mini-LED backlit LCDs and OLED displays, especially in the notebook market, has been conducted [11]. To increase the dynamic range in VR headsets, mini-LED backlit LCDs are also employed in VR headsets [12].…”

“…To increase the dynamic range in VR headsets, mini-LED backlit LCDs are also employed in VR headsets [12]. The comparison reported in [11] can be also extended to VR displays. Figure 1 describes the system configuration of a mini-LED backlit LCD.…”

“…As for contrast ratio, the mini-LEDs can be employed to increase the contrast ratio of the LCD [16]. With the help of mini-LEDs, the VA mode will not outperform the FFS mode in terms of contrast ratio.…”

Opportunities for cost-effective manufacturing of fully printed high performance displays enabled by vertical light-emitting transistor pixels

“…LCD and active-matrix organic light-emitting diode (AMOLED) are at present the dominant flatpanel display technologies [12,13]. While more mature and completely commoditized LCD displays still holds the majority share of mid to large size panels, AMOLED has successfully captured a majority of the small size display panel market (smartphones and watches) and is making inroads into the mid (laptop) and large size (TV) display territory [14][15][16]. Currently AMOLED displays represent the high-end display panels due to several comparative advantages, including higher contrast, quicker response time, wider viewing angle, and a thinner and flexible form factor, all of which help AMOLED panels enjoy a high profit margin [17][18][19].…”
