I originally thought that MiniLED iPad Pro would be the last glory of LCD, but it turned out to be PWM dimming. It seems that eye protection and viewing experience cannot have both

Originally 618 really wanted to buy a tablet for watching HDR movies (Dolby Vision, HDR vivid). I originally thought that all Android tablet flagships are currently LCD, but now that Apple has switched to OLED, the best experience to watch HDR with LCD should be MiniLED. After all, the Sony at home is very good-looking to watch Dolby Vision. Unexpectedly, the MiniLED of the iPad Pro is also PWM dimming, which means that the eye protection advantage of LCD is actually gone. Now I can't figure out what screen type to buy. OLED really feels blind, but I want to watch high-quality HDR movies. Axi, it's really GG

    @ Anonymous966 oled TVs are generally DC dimming

    I still remember the era when everyone thought that no anti-blue light mode was no eye protection. How many people turn on this function now?

    @ Anonymous10584 I still have this function on now

    @ Anonymous10584 Because most devices have hardware protection against blue light

    Why don't you look at pwm dimming and be afraid What has been criticized is the low-frequency pwm dimming of one or two hundred hz. Is it good? The pwm dimming frequency of lcd can start from several thousand hz

    @ Anonymous1719 In the past, when there was no hardware to prevent blue light, the screen would be particularly yellow when turning on the anti-blue light, but now it's just a little yellow
  • Anonymous1719 May 27, 2024
    @ Anonymous8944 The reason why the LCD screen produces blue light is that the light source of the LCD uses light around 450nm to excite other colors, so there will be a little blue light leakage. The principle of preventing blue light is also very simple. If the light source is switched to a wavelength of 460nm, there will be no problem. Because the OLED screen emits native light, there is no blue light problem.

    @ Anonymous8944 The screen is RGB. If you don't want B, then RG is left. Of course, it's yellow. Now it's not that yellow, just secretly gave some B

    Why don't I feel anything after using my OLED TV phone for so long? What exactly is dimming!

    Stroboscopic vision loss is pure pseudoscience It's similar to having a 5G antenna in a letter mask Most fluorescent lamps are far below so-called low-frequency pwm dimming Few companies use high-frequency flashing fluorescent lamps for decoration Basically, as long as it can light up, led fluorescent lamps have not seen you say that vision has decreased in decades In addition, earlier CRT monitors, fluorescent lamps and incandescent lamps flashed below 60hz or even 50hz You can see the stroboscopic flicker with the naked eye, but few people take it out and say it affects your eyesight By the way, something more funny is that the hardware anti-blue light eye protection screen is interlayered with powder in the screen This actually produces a low-frequency blue light strobe As a result, many people say that it is okay to watch the eye screen blindly when watching oled stroboscope Pure placebo effect

    @ Poster 11-inch 20Pro is high-frequency pwm, 1316hz, others are dc; 12.9 inches are all pwm except 18Pro, which is dc, 20Pro is 50000 + hz, 21Pro is 19000 + hz, 22Pro is 6400hz, 18 forward is not clear
  • Anonymous2893 May 28, 2024
    @ Anonymous2305 So the 22 Pro 12.9 inch is actually PWM dimming, but it's a high frequency of 6400Hz?

    Should you also look at the changes of your own screen usage time?

    @ Anonymous3681 # 32 The fluorescent tube you mentioned has afterglow benefits if it is a fluorescent lamp. This is the same as ccfl and cannot be directly compared with led strobe. The ccfl eye protection is the same as hanging lcd. Incandescent lamps are full-spectrum, which has nothing to do with stroboscopic flashing. If you say incandescent lamps are blind, you are saying that the sun is blind. If it is led lights, high frequencies have long been popular, and only signboards or decorations will use low frequencies. This is obvious when SLR photos are often taken.

    If your sony TV is zoned backlit, it should also be PWM dimming. If you can accept it, it means you are not sensitive to PWM

    @ Anonymous12996 Sure enough, human beings only want to believe what they believe, even if what they say is contradictory
  • Anonymous2239 May 29, 2024
    @ Anonymous3681 Nowadays, all of them are LED light tubes, and many of them have no video flashing. How can there be old-fashioned fluorescent lamps used for company decoration...
  • Anonymous2239 May 29, 2024
    @ Anonymous12996 Because you use alternating current, the incandescent lamp also flashes, but the flashing depth is not very deep... If the shutter of the mobile phone is opened for a shorter time, you can catch the incandescent lamp flashing.
