      Not burn-in: Scary OLED TV image retention may stem from “buggy” feature

    Image retention is scary to see on your OLED TV but often easy to eliminate. Many modern OLED TVs subtly work their own magic when you're not watching in order to remove the problem, as RTINGS demonstrated in a video released Friday. However, TV vendors aren't all doing perfect jobs at implementing OLED screens' compensation cycles.

    Temporary image retention differs from permanent image retention, aka burn-in, in that it points to a change in the panel's thin-film transistor (TFT) layer, rather than degradation of the OLED layer. Untreated permanent image retention doesn't lead to burn-in, a Sony spokesperson confirmed to me, but anyone looking at a screen suffering from image persistence will want to eradicate the sticky images, fast.

    These temporary artifacts can be the result of heat affecting the amount of light emitted by the OLED pixels and can happen within minutes of usage. But letting the TV cool down by turning it off usually fixes this.

      TCL backtracks on making its first OLED TVs

    TCL isn't letting go of the QLED dream. This dream doesn't just see TCL selling LCD-LED TVs with quantum dots but also features QLED as the sole four-letter acronym in its lineup. Numerous vendors announced new OLED TVs during CES 2023 last week, with some leveraging purportedly next-gen tech. However, TCL has affirmed plans to be one of the last TV makers still holding out on OLED... despite what you may have heard.

    During CES, TCL actually did announce that it was making its first OLED TV. It even went as far as to commit to Samsung Display's QD-OLED panels, which would make it the third company to sell QD-OLED TVs, after Samsung and Sony. The announcement claimed that Mini LED and QD-OLED would "both hold premium positions in TCL's 2023 TV line-up." However, the TV maker known for budget and mid-range products told FlatPanelsHD today that this is false.

    "A line in the TCL CES 2023 press release confirming plans to launch the brand's first QD-OLED television this year was incorrectly included," TCL told the publication.

      How will 2023 TVs address OLED’s biggest flaws?

    OLED TVs are the premium focal point of many modern-day home theaters, but they're still imperfect technology. As usual, last week's CES in Las Vegas featured a smattering of upcoming TVs, plenty of them OLED-based. We saw bigger sizes and increased competition among OLED panel makers; however, the most interesting development was claims of boosted peak brightness.

    A dimmer screen has long been the weak point of OLED displays, especially compared to their cheaper LCD rivals. But while 2023's upcoming OLED TVs largely trumpet improved brightness capabilities and present potential for unprecedentedly rich highlights, it'll still be years before you want to put an OLED TV in your sun-filled living room.

    OLED's brightness problem

    If you listed the drawbacks of an OLED TV compared to an LCD one, they're typically price and dimness. Despite having inky, deep blacks, OLEDs are known to be noticeably dimmer than LCD displays. Dark blacks still help the screens deliver next-level contrast, and good OLED TVs can make highlights in HDR content pop dramatically. But less overall luminance makes it hard to enjoy the image on an OLED TV in a brightly lit room or positioned under a light.

      LG’s 2023 OLED TVs claim to boost brightness by up to 70%

    January means new technology product announcements from the CES trade show in Las Vegas. LG, a regular CES participant, announced this year's OLED TV lineup at the show. Similar to LG's 2022 OLED TVs , this year's focus is about boosting brightness. But in 2023, LG's OLED TVs will also face stiffer competition, including from Samsung Display's QD-OLED tech, which is also supposed to be getting brighter.

    Today, LG announced updates to its 8K Z series (77 and 88 inches), high-end 4K G series (55–97 inches), and flagship 4K C-series (42–93 inches) OLED TVs. The company didn't detail new additions to its less advanced B series, but Forbes reported that LG would eventually release B3 OLED TVs with an A7 Gen 6 processor and 55-, 65-, and 77-inch sizes this year. LG will reportedly no longer sell the entry-level A series in North America.

    In addition to using OLED.EX panels (which LG calls "OLED Evo" in its consumer TVs), LG Display announced in late 2021 that OLED.EX panels were up to 30 percent brighter than traditional OLED panels; LG also claims the 55-, 65-, and 75-inch G3 are up to 70 percent brighter when using a feature called Brightness Booster Max. The feature isn't available on the 83- or 97-inch G3 or any other LG OLED TV series.
