More efficient and brighter: LG introduces new 4th generation OLED screens 4 comments

Like Samsung with its QD-OLED screens, LG is extending its OLED screens for televisions to the 4th generation. LG has now given up on microlenses (MLA) and is now relying on a new four-level design. On the one hand, this should achieve 4,000 cd/m² and, on the other hand, increase efficiency.
New 4-layer OLED structure
LG Display speaks of “Tandem Primary RGB” and now refers to the 4-layer OLED design. While the third generation uses three layers, two blues and one red, green and yellow in one layer, there are now four: two blues in combination with red and green, each in its own layer.
With this configuration, the maximum brightness of white light could be increased to 4,000 cd/m² (+33%) as well as the brightness per color. The latter should now reach 2,100 cd/m², or 40% more than the 3rd generation with a maximum of 1,500 cd/m². All information only applies to a small area, which is 3% of the image area.

With improvements to the panel structure and power supply, TVs should operate more efficiently. In the press release, LG speaks of a 20 percent increase in energy efficiency compared to a 65″ panel of the previous generation. In the promotional video for the new OLED generation, we again see a reduction of 20 percent in power consumption while at the same time, an increase of 33 percent in maximum speech brightness, which sows confusion.
As Techtip learned in advance, LG also does without MLA technology with microlenses in the fourth generation, as it is used in the third generation.
New anti-reflective coating
Incoming ambient light is known to cause annoying glare and distorted colors, so black appears as gray in bright sunlight. A new coating is intended to balance both the light reflected off the surface and the light absorbed and reflected inside the panel, LG says. Thanks to this “very low reflection technology”, 99% of internal and external light reflections are blocked, we continue. The manufacturer announces that there should be perfect black and accurate colors even at midday in a bright living room with 500 lux ambient light.
First high-end TVs, then gaming monitors
First, LG Display will place the new technology in the high-end TV market. Among them is the new G5 series, marketed under the name “LG OLED Evo AI”.
Later, gaming monitors will also work with a fourth generation OLED panel.
Samsung also reached 4,000 cd/m²
Samsung’s fourth generation of QD-OLED displays are also expected to reach 4,000 cd/m². Samsung now even uses 5 OLED layers.
