Micro-Lens Array (MLA) - Page 2

According to reports from Korea, both Samsung Display and LG Display have approached Apple, offering to produce MLA (Multi-Lens Array) AMOLED displays for a future iPhone device. Applying the MLA panel will increase the light output, but will carry higher costs and may also reduce the viewing angles (or actually reduce the side-view brightness).

It is not clear what kind of effect will MLA offer in Apple's case. When LG applied MLA to its TV panels, the company says it improved the brightness by 60% (it also stated that viewing angles actually increased by 30%). Apple will not be the first one to apple MLA to smartphone displays - Samsung itself adopted MLA panels in some of its high-end models (Galaxy S Ultra phones) and so did some other vendors.

LG Display demonstrated several exciting OLED display prototypes at Display Week 2023.

First up was the company's 77" 8K Meta (microlens-array) panel - this has been commercialized already, but it is always a wonder to watch this particular display which offers an extraordinary image quality.

According to reports from Korea, LGD is now applying MLA to its gaming monitors, as it sees the growing gaming market as an important one for its future growth.

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 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.

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.

TCL (CSoT) announced that the company has finalized the development of several new OLED technologies, which has been deployed at the company's production lines.

The first technology is LTPO, or Low-Temperature Polycrystalline Oxide, an OLED backplane technology developed originally by Apple. LTPO enables variable refresh rates, and TCL's technology can support a wide range of frequencies, from 1Hz to 144Hz.

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.

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

The so-called MLP panel is 6.2" in size with a 876x2142 resolution (373 PPI) and a brightness of 420 nits. The pixel configuration is, interestingly, YYG - yellow and green sub-pixels, which means that this display uses color filters.
