Aside from the entry-level phones, most of the smartphone company uses OLED panels to provide a high and more durable viewing experience that worth their money. However, even a high-priced, OLED screen-equipped phone could bring you headaches or eye strain.
There could be a number of reasons for these head and eye-related issues found in a smartphone’s display including high brightness, blue light, and incorrect colors. There’s one more thing you need to about the display issue called Screen Flickering.
What is Screen Flickering:
It’s a bit of a technical description, so bear with me here.
Flicker is a quick oscillation of light output between on and off; it is measured in hertz (Hz) to quantify the frequency at which the oscillation occurs. While we may not be consciously aware of the flicker phenomenon, it’s important to understand that our eyes still physically respond to it — that is, our irises expand and contract in response to these changes in brightness.
This involuntary physiological response can certainly explain why we may have a headache and particularly why our eyes can feel tired after looking at a display for an extended period of time — they have been working hard! (This is especially true when looking at a display in dark ambient conditions, such as reading in bed with the lights turned off, for reasons we’ll check on this more below.)
What Cause Flicker:
It is unfortunate that flicker on their displays (especially OLED displays) is still an issue for many people. That’s not the issue, but why do they flicker?
Let’s take a dig at Flicker:
Smartphones either come with LCD (liquid crystal display) or OLED (organic light-emitting diode) technology. LCDs don’t emit their own light, rather, they are back-illuminated by a strip of LEDs whose light intensity is quite powerful so as to compensate for the brightness drop due to the low transmission rate of the LCD panel (caused mainly by the RGB color filter). By contrast, in an OLED display, every pixel is itself an OLED that produces its own light.
Both LCDs and OLED displays are composed of light-emitting diodes, therefore, a diode’s intrinsic physical properties, cannot be dimmed by changing the intensity of the current (mA) without changing the color of the light.
How manufacturers dim Displays?
According to DXOMARK, Using a technique called pulse-width modulation (PWM), which is responsible for turning the diodes off and on at varying rates. Because, we normally should not be able to see this switching between off and on (in other words, flickering!), it’s a trick for our brains that precise that the screen as simply dimmer overalls (a phenomenon is known as the “brain averaging effect”).
The dimming depends on how long the diodes are off versus how long they are on, the longer they’re off, the dimmer the screen will appear.
So both LCDs and OLED displays power their light sources differently, but both technologies are subject to flicker effect; however, it is usually more noticeable on OLED displays than on LCDs.
For one thing, OLED displays and LCDs show PWM at different frequency ranges — the PWM of OLED displays range from 50 to 500 Hz, whereas the PWM of LCDs starts at around 1000 Hz or higher. Second, as the human eye may experience flicker sensitivity up to about 250 Hz (at least for most people), it should come as no surprise that OLED displays are more likely to cause eyestrain than LCDs.
Huawei EMUI 11:
These same issues are also presented in high-end Huawei devices and with recent versions of EMUI, Huawei has sent a new feature called flicker reduction to reduce the screen flickering.
This feature will reduce the number of your screen flickers and may also affect its color and brightness but one thing know that it also consumes power.
- Open Settings
- Display & brightness
- Eye comfort, then enable or disable Flicker reduction
Huawei Mate 50 series to equip six blade aperture camera lens: Tipster
Last year, the WIPO has approved a Huawei Patent, entities ‘Aperture camera module, and an electronic device describing a six-blade camera aperture technology. And it is recently reported that the Huawei Mate 50 series to equip with this six-blade aperture camera technology.
According to a well-known Weibo tipster, the Huawei Mate 50 series will become the first Huawei phone to equip the six-blade camera aperture module, with the expected current aperture range of engineering matching F1.4-F4.
Camera aperture diaphragm:
The best example to describe the aperture camera is the Samsung Galaxy S9, the smartphone equipped the 8-blade aperture technology. While the Huawei Mate 50 is expected to bear only six-blade technology.
Similar to a shutter, a camera diaphragm controls the quantity of light that reaches the sensor while also shielding the lens from damage. As a result, it indirectly affects the camera’s depth of field and aperture.
On the other hand, an image with a more blurred background can be captured using a wider aperture. Even in low light, we’ll still have crisper photographs. The depth of field and exposure, however, is constrained because smartphones have fixed aperture lenses.
The tipster further stated that Huawei Mate 50 Pro houses a 15x telephoto macro with longer bangs, and the Mate 50 RS will support a 35x telephoto macro lens camera.
Huawei Mate 50 series launch:
There were so many leaks and rumors appear related to the launch of the Huawei Mate 50 series. And going with the latest info, the Huawei Mate 50 series is to launch on September 7. Still, the date is not confirmed by the company let’s see, when Huawei will give its official launch date of the next upcoming flagship lineup.

However, if the recent leak of six-blade aperture camera technology comes with the Huawei Mate 50 then this series will become the most prominent and innovative in terms of design, specs, and features.
6G is not simple upgrade of 5G, but a leap forward: Huawei
Huawei has participated in the World 5G Conference held in Harbin, this morning. The conference mainly discussed the benefits of the 5G and 6G upgrade network technologies that Huawei and its developers are trying to bring across the globe.
6G mechanism is a spectrum of multiple layers. It utilizes the low-frequency band for the simple coverage channel and uses the mid-range frequency for the moderate network. The high-frequency band ultimately boosts the experience of the network for the users.
According to the latest information, Huawei narrated how the 6G network mechanism will ultimately prove a boon for the users. Clarifying that 6G innovation is just not an upgrade but more than that, the President of Huawei Wireless Network Product Line and Chief Scientist of 6G tech – Wang Jun delivered the following words:
“6G is not a simple upgrade of 5G, but a leap-forward improvement. It is the only way for a unified global infrastructure of the digital economy. Huawei will keep working with partners to promote global unified standards and will keep on bringing new creations for the welfare of users, in future also.”
Apart from exhibiting the company’s intention toward digitalization, the President also explained the crucial directions of the 6G technology. Accordingly, the 6G network transformation stands over six technical directions.
For instance, native intelligence, extreme connectivity, network perception, star-ground fusion, native trustworthiness, and carbon neutrality.
Further, Wang also mentioned that the company has brought the 6G vision to amplify the human connection, internet stuff, and more. In other words, Huawei is looking forward to a smart and intelligent scenario for its users in the time ahead.
The Chinese tech maker believes that the correct definition of 6G is to increase the intelligence as well as perception facilities based on the upgrade of some major scenarios of 5G.
Six Typical Application Scenarios
The 6G technology has the following applications that will help in accelerating the network operations:
- Distributed networked machine learning and connected AI
- Perception, localization, and imaging
- Human-Centered Immersive Communication
- Smart city and smart life
- Full-featured Industry 4.0 and its evolution
- Global coverage of mobile services.
As per the information, the 6G technology is in expectation to arrive by the year 2030. But we still require confirmation from the side of the company.
Huawei introduces key factors of its optical hybrid cable
Huawei is constantly introducing some or other technology-based solutions that can serve various benefits to the users. Today, the company has introduced some key factors of Huawei optical hybrid cable and described how useful it could be for network and transmission purposes.
The Chinese manufacturer has officially posted a video on its Weibo channel, this morning. On exploring the post we found, how the optical hybrid cable of Huawei plays a crucial role in the technology sector. So let’s learn about this unique cable bit by bit.
An optical Hybrid Cable, also known as the optoelectronic cable is a package of cables that binds the original two wires of the cable into one wire. Ultimately, this mechanism will help in obtaining secure software and hardware coordination.
Besides, it will negotiate data packets that the operators transmit through optical fibers, and will carry the power supply through twisted pair of cables. Another benefit of the optical hybrid cable is, unlike other network cables, this technology is quite affordable.
Moreover, the wire diameter is also thinner, and can easily stretch the bandwidth and transmission distance, irrespective of time. Consequently, this is the farthest power supply distance that can reach more than 1000 meters at a time.
A huge aid for traditional problems:
So far, the office building generally consists of long distances as well as several clients connected to one server. As a result, it becomes difficult for the core computer room to even transmit 100 meters of the network in the area. Aside, this problem was not a matter of a simple optical mechanism that can easily resolve the situation.
However, the combination of optical hybrid cable as well as Wi-Fi 6 can mark an end to the above-mentioned issues. Fortunately, the respective technology provides 10Gbps ultra-wide access and 300-meter ultra-long distance PoE (Power over Ethernet) power supply.
Furthermore, after the remote module gets a sufficient power supply, it can support 4 Wi-Fi 6 networks without requiring local power extraction. Its capability is so flexible that operators can easily relieve for 10-15 years after applying this technology.
