OnePlus News Daily Dose #43: DC dimming, OnePlus 7 case leak, Bullets Wireless V2 and more!

In the domain of smartphone manufacturing, the choice of display components is often considered as an indicator of the target market segment. AMOLED displays used to be reserved for premium class phones, while budget models were stuck with IPS LCD panels.

OnePlus debuted AMOLED display panel with 2015’s OnePlus X. Its bigger sibling, i.e. the OnePlus 2 was launched with IPS LCD – same as 2014’s OnePlus One. Starting with OnePlus 3, every OnePlus phone packs an Optic AMOLED display panel.

In a reddit AMA session, OnePlus co-founder Carl Pei described the display tech as follows:

According to Carl, OnePlus engineers fiddled with the Samsung made hardware and tinked the software as well to tune the display tone.

Even something like color tone is a combination of hardware and software.

Avid users of OLED displays are familiar with the infamous display flickering issue in low brightness mode. I would suggest to take a look at the following video to get an idea of it.

In a nutshell, OLED panels use the method of Pulse Width Modulation (PWM) to control the backlight brightness. Although the flickering should be unnoticed by the average human eyes, people with sensitive eyesight often feel discomfort and headaches caused by it.

DC dimming is a popular solution to tackle this glitch of the OLED displays by adjusting the DC current voltage. As the voltage goes up or down, a paired up driver matches the light output of the LED panel to increase or decrease up to the appropriate percentage.

DC dimming is gaining attraction among smartphone makers. Xiaomi already shipped the feature in their gaming oriented Black Shark 2 phone.

Mi 9 is also getting this feature via beta version of MIUI. Other Chinese OEMs, like Vivo, Meizu as well as OPPO are working hard to bring DC dimming in their phones.

OPPO’s VP Bryan Shen demonstrated the hands on effect of the DC dimming feature in a video.

Given the close relationship between OPPO and OnePlus, it’s just a matter of time the feature to come in OxygenOS. In fact, OnePlus CEO Pete Lau has revealed that the company is currently evaluating DC dimming and their effects.

The rough translation indicates that they still need to polish it up before shipping, as the current result the of the engineering testing is not up to the mark.

We hope that the upcoming OnePlus 7 will support DC dimming out of the box, while older models will get the same via future software updates.

Talking about OnePlus 7, Slashleaks contributor Sudhanshu Ambhore has shared a number of case renders which are allegedly for the upcoming OnePlus phone.

The renders second the rumored triple rear camera setup of the OnePlus 7. The slightly asymmetrically placed popup selfie camera hole can also be noticed.

The newly leaked case renders are pretty much aligned with the CAD renders we saw before from OnLeaks. Interestingly, the SIM card slot can now be seen at the bottom of the phone.

Meanwhile, leakster Ishan Agarwal spotted the pictures of the purported second generation OnePlus Bullets Wireless headphones.

Followers of OnePlus Daily Dose should remember that we speculated the arrival of the next iteration of OnePlus wireless headphones based on a Weibo post made by Pete Lau.

Leaks, leaks, go away

Come again another day

On the other hand, the Windows 10 ARM porting process to OnePlus 6T is progressing with the full swing. Bas Timmer, aka NTAuthority has got the touch screen and CPU multi core utilization working.

Although it looks fascinating, you will certainly lose the OnePlus camera features after installing the Windows 10 port (well, still a long way to go).

For example, you can not capture moments like Tom Pagès doing freestyle motocross stunts in front of the Gateway of India!

Let’s call it a day; see you guys tomorrow!
