Explaining OLED screens and Dark Mode

Why that screen fits in the dark

Published

on

Most of the applications you’re currently using must have rolled out their own version of dark mode by now. The smooth transition from a light to dark interface can be done through a push of a button, or by sending the moon emoji on Messenger. A lot of people also find dark mode quite sexy, and that’s probably because of the screen they’re looking at.

A lot of newly released smartphones now have OLED screens, and dark mode seems to work best on such displays! But why is that? How do OLED panels allow dark mode to flourish?

Better, blacker, affordable screens

Organic LED (light-emitting diode) or OLED is essentially a kind of display technology. In a nutshell, OLED panels allow for better and clearer images and colors.

Thin layers of carbon fiber make up OLED screens. Because of these lightweight fibers, screens show brighter and more vibrant colors. Apart from that, OLED screens show deeper blacks and reduce instances of motion blur when navigating. The best part is that OLED screens are becoming gradually cheaper to manufacture. That explains why more and more of today’s smartphones use this panel.

More colorful than the rest

In comparison to regular LED screens of the past, OLED promises more accurate colors by producing light from individual pixels, instead of relying on backlighting. Back then, LCD screens relied heavily on the backlight of the display to make colors pop. Although, such displays also make the colors seem washed, especially when compared to OLED.

However, OLED’s colors don’t always turn out better than on LED and LCD screens. One such case is when you turn your screen’s brightness to its maximum, especially under strong daylight conditions. LED and LCD screens are designed to perform relatively better in color accuracy when your screen’s brightness is set to max. OLED screens were not designed for maximum brightness, so colors at that point would be saturated.

Which OLED is best?

There are two types of OLED technologies that currently exist: AMOLED and PMOLED. A lot of people hear AMOLED tossed around a lot because lots of smartphones use it. Essentially, AMOLED uses a storage capacitor that controls how much light each individual pixel will give off. It’s the one responsible for projecting all sorts of vibrant colors on most OLED smartphone screens. Apart from that, AMOLED screens do support wider resolutions at a more affordable and efficient rate.

PMOLED, on the other hand, does not have a storage capacitor and instead relies on user control. Essentially, the user will control lighting settings, and the individual pixels will adjust accordingly. You can find PMOLED screens on smaller devices like older iPods and pocket Wi-Fi devices. Take note that these screens use more power to implement such color changes.

Joining the dark side

Ever since dark mode rolled out for different apps and interfaces, people have been contemplating on switching to it — and for good reason. On normal LED or LCD screens, the new feature does not bode well with the technology. The depth of the black their dark mode possesses is not reflected well, to the point that the blacks look more gray than actual black. This is much more obvious when the screen’s brightness is turned all the way up.

Aesthetically, dark mode looks better on OLED screens because of the technology’s emphasis on deeper blacks. Most OLED screens have capacitors that control light passing through each pixel, which also works for blacks and whites. As such, dark mode shows up deeper and blacker, which is the intended look compared to regular modes. But, there’s actually more to just aesthetics for this mode.

It’s also been proven that dark mode on OLED helps save your battery life. Google confirmed this at its Android Dev Summit, citing that on max brightness, blacks consume less power than all other colors. Individual pixels need less electricity to show blacks on screen, which results in lower power consumption through time. Note that Google got these findings through tests on their original Pixel smartphones and their own apps like YouTube.

What’s left for OLED and dark mode

Apps and operating systems are now starting to embrace or consider incorporating dark mode into their software. While apps like Twitter and YouTube introduced such an option early on, others are beginning to take notice. Of course, you’re gonna need the right screen to fully immerse yourself.

It has been proven: OLED and dark mode are indeed a perfect match. But, it is entirely up to you whether you want to stay in the light or switch to the dark side.

CIPTA Industrial Sdn Bhd steps onto the global stage with its European debut at CloudFest 2026. They introduced high-density AI infrastructure and edge-ready systems built for modern enterprise workloads.

Held at Europa-Park in Rust, Germany from March 23 to 26, the event marks the company’s first major international showcase under its own brand. Backed by InWin Development Inc., CIPTA positions itself as a new-generation EMS provider focused on AI, cloud, and enterprise systems.

At Booth R41, the company is highlighting two key platforms: the RG658 PRO GPU server developed with Phison, and the cubePRO edge workstation created in collaboration with Accordance.

Built for scalable AI workloads

Leading the showcase is the RG658 PRO, a high-density GPU server designed to handle large-scale AI training and inference without pushing costs out of reach for enterprises.

The system supports up to eight high-performance GPUs and integrates Phison’s Pascari aiDAPTIV alongside its PASCARI enterprise SSD lineup. This combination aims to improve data throughput, reduce latency, and streamline AI pipelines.

Thermal performance is a key focus. The RG658 PRO uses a dual-chamber design to separate heat zones, paired with up to 14 high-speed PWM fans for sustained cooling under heavy workloads. Power delivery is handled by a 3+1 redundant configuration of 80PLUS Titanium PSUs, scaling up to 9600W.

The result is a platform built to scale AI deployments on-site while maintaining efficiency and reliability.

Edge computing without downtime

Alongside its GPU server, CIPTA is introducing the cubePRO, a compact edge workstation designed for environments where uptime and data integrity are critical.

The system supports up to four PCIe slots for GPU configurations, making it suitable for AI workloads at the edge. It also features high-capacity multi-SSD setups and optimized airflow for continuous 24/7 operation.

Through its partnership with Accordance, the cubePRO integrates the Disk Array ARAID M500 solution, enabling high-availability storage and data protection. This ensures uninterrupted performance for use cases such as industrial systems, remote nodes, and enterprise branch deployments.

The focus here is clear: bring AI processing closer to where data is generated, without sacrificing reliability.

Strengthening Malaysia’s role in AI infrastructure

CIPTA’s debut also reflects a broader shift in global supply chains. Operating from Malaysia, the company offers end-to-end services—from concept to production—along with flexible manufacturing cycles and cost-efficient operations tailored for Southeast Asia and international markets.

With access to InWin’s server chassis ecosystem and infrastructure solutions, CIPTA combines global platform capabilities with localized integration. The goal is to help enterprises deploy AI and cloud infrastructure faster while diversifying their supply chain footprint.

As demand for AI systems continues to grow, CIPTA is positioning Malaysia as a key hub for scalable, production-ready infrastructure.

Visitors can find CIPTA at Booth R41 during CloudFest 2026 in Europa-Park, Rust, Germany.
