LG Displays adopts its MLA technology to its new gaming monitors

Last month LG Display announced its META technology, which is a micro-lens array (MLA) that increases OLED brightness by around 60% and viewing angles by 30%. The MLA technology was first adopted in LG's high-end TV panels.

LG confirms its latest OLED TV panels use microlens arrays, brands it as META Technology

A few days ago LG Electronics unveiled its 2023 OLED TV range, which included the OLED G3, LG's slim all-in-one design OLED TV which is LG's brightest OLED TV yet. As we reported, LG Display announced today that its latest OLED panel adopts a micro-lens array to boost the performance.

Branded as META Technology, the OLED Panel is covered with a micro lens array to maximize the light emission. LGD says that this increase the brightness by 60%, and also increases the viewing angles by 30%. The G3 panel has a peak brightness of 2,100 nits.

LG Electronics announces its 2023 OLED TV range

LG Electronics announced its OLED TV range for 2023. LG is introducing several new technologies, one of which is microlens array (or MLA) to achieve up to 2,100 nits (in the G3 series).

The entry-level model is the A3 series, which offers 4K 60Hz 48-inch, 55-inch, 65-inch and 77-inch WOLED panels. The A3 offers WebOS 23, HDR10, Dolby Vision, Dolby Atmos, HDMI 2.1 VRR and support for G-Sync and FreeSync Premium. The B3 series is similar, but with support to 120Hz.

LG Display may start producing microlens MLA WOLED panels by 2024

In May 2022 we reported that LG Display is looking into adopting a microLens array in its large OLED TV panel architecture. The microlens layer could boost brightness by up to 20%, which will also increase efficiency (if brightness is kept as before). According to a new report from Korea, LGD is progressing in its project and estimates that the first MLA (Micro Lens Array) OLED panels will enter production in 2024.

The original report in May stated that LGD could actually begin producing MLA OLEDs as early as in 2022 - but it seems as this was overly optimistic. Earlier this year, LGD demonstrated a 77" 8K MLA WOLED panel.

LG Display demonstrates a prototype WOLED display with a microlens MLA array

As we reported last week, LG Display is developing OLED TV panels that utilize a microlens array to increase the light output. LGD unveiled its first prototype display at SID Displayweek 2022.

LGD is showing a 77" 8K panel that features what the company refers to as Meta-lit Lens Array, or MLA technology. The MLA layer increases light output by more than 20%, and the panel achieves a brightness of 2,000 nits. LGD says that the viewing angles is also increased using the MLA technology.

LG Display could adopt a microLens array in its OLED TV panels to boost brightness and efficiency

Reports from Korea suggest that LG Display is looking into adopting a microLens array in its large OLED TV panel architecture. The microlens layer could boost brightness by up to 20%, which will also increase efficiency (if brightness is kept as before).

According to the report, the project is at an advanced stage, and panels with the microLens array could be introduced by the end of this year. LGD will apply the technology to its OLED.EX panels, so brightness could reach up to 1,200 nits. LGD considers this technology as it faces competition in large-area OLED production, from Samsung's QD-OLED panels, for the first time.

Tianma shows a microLens AMOLED panel with improved power consumption

Tianma demonstrated a new AMOLED display panel at SID Displayweek, that sports a micro-lens array that helps to decrease power consumption by 10-15%.

Researchers develop a sub-electrode micro-lens array that can increase the light output in OLEDs by a factor of 3

Researchers from the University of Michigan developed a new method to cost-effectively extra more light out of OLED displays. To achieve that, the researchers used a Sub-Electrode Micro-Lens Array (SEMLA) placed between the bottom transparent ITO electrode and the glass substrate. Testing on green and white PHOLEDs, the researchers say the SEMLA enhanced light output by a factor of 2.8 (green) and 3.1 (white) compared to a similar device without the lens array.

The researcher say that such an array can be fully transparent and has no impact on the sharpness of the display. The hexagonal array of 10 um lenses can be fabricated using conventional photolithography methods which are quite cost effective. Such a micro-lens array does not change the actual OLED production process.
