We already heard word that Samsung Display is gearing up to commencement Galaxy S27 show manufacturing soon. That mightiness person already happened; hence, these caller leaks mightiness beryllium perfectly plausible. Apparently, the S27 Pro and S27 Ultra volition beryllium the archetypal Samsung smartphones to connection DC dimming. That sounds similar it can’t perchance beryllium true, and yet a speedy hunt aboriginal – indeed, adjacent the Galaxy S26 Ultra relies connected accepted PWM to set its brightness.
Simplifying things a bit, successful lawsuit you don’t cognize what we are talking about, PWM (Pulse Width Modulation) is the accepted mode of adjusting a display’s brightness. It fundamentally flickers the airy root (backlight oregon the pixels themselves successful self-emitting show tech) precise rapidly connected and disconnected to execute antithetic perceived brightness. It works, but it is benignant of a “hack” relying connected however our eyes work, and immoderate radical are really beauteous delicate to the method and tin endure oculus fatigue and adjacent headaches. The solution we person is DC dimming. It really adjusts the voltage input to the airy source, truthful nary nasty flicker. It is overmuch harder to do, though, particularly connected modern displays with different features similar adaptable refresh rate.
That doesn’t mean it’s impossible, though, conscionable difficult. Open, say, a caller flagship Xiaomi instrumentality specs sheet, and you volition instantly spot adaptive refresh complaint with LTPO tech and optional DC dimming. That is inactive a technological hurdle, similar we said, and often requires a hybrid attack wherever mean to precocious brightness levels usage DC portion low-brightness levels power to PWM. Still, it tin beryllium done, and it’s mostly to the user’s payment and comfort.
Anyway, much to the point, a rumor has surfaced claiming that the S27 Pro and S27 Ultra volition yet connection DC dimming. At slightest successful immoderate capacity, that is, since a hybrid attack mightiness inactive beryllium required. This is seemingly different happening that is portion of the wider S27 show “split”. As per sources, the Pro and Ultra volition get Samsung’s latest M16 OLED worldly formula, portion the regular S27 and the S27 Plus volition get M14+. Another show differentiator is besides the Privacy Display feature, introduced successful the Galaxy S26 Ultra. Apparently, it is sticking astir connected the S27 Pro and S27 Ultra.
Frankly, it is benignant of astonishing that Samsung is retaining the frankly niche Privacy Display diagnostic that is beauteous analyzable hardware-wise and sounds similar overmuch much of an concern than the determination to DC dimming. And portion connected the subject, we don’t privation to dependable similar we don’t admit the imaginable addition, but wherever is due hardware 10-bit colour support? Some competitors are already offering 12-bit color.
Before you airy up the remark section, we get however system of standard works some ways and that successful insanely high-volume models, redeeming adjacent cents makes immense sense. And, conscionable to support things arsenic balanced arsenic possible, it’s not similar Samsung is the “greedy villain” here. Apple iPhones don’t truly person DC dimming either. They person a “smooth PWM” mode successful settings. And determination is nary hardware 10-bit colour connected iPhones either. So if you’re going to beryllium huffy astatine anybody, it should astir apt beryllium the “big guys”.
