What portable monitor is the best partner for MacBook

The kiperline sky line gen 9 display portable screen is similar to the Gemini I checked earlier this year.

Portable-display1

It has many similarities with Gemini. It is battery-powered again and can be really used in mobile devices. The display is still 15.6-inches, and you can again choose the 1080p touch screen version and the 4K model without touch display performance. Although Mini DisplayPort has been eliminated, you can still get both USB-C and HDMI inputs.

But the layout of BladeX is more stylish. Now the thickness of the entire display is no longer fifty percent of fifty percent of an inch, and no longer half an inch. The folded base is still only half an inch thick, so you don’t really get any mobile advantages, but there is no doubt that the slimmer layout is aesthetically attractive…

I chose to evaluate the 4K version again, which is a fully useful model again. (I do think touchscreen Macs will benefit regularly, but it’s not worth giving up resolution.)

The appearance of BladeX.

BladeX has a stylish appearance in gunmetal metallic gray. The leadership and side structure are very slim, while the bottom chin is quite large.

The coating is a fascinating combed lightweight aluminum with the exact same color as one of Apple’s many deep space gray shades.

The base is folded under the backrest to form a stand. The angle is absolutely flexible, from completely upright to completely horizontal.

On the left side of the upper dock is a USB-C port for connecting to a Mac and an additional for charging, HDMI input and headphone jack. On the right are two MicroUSB ports and three multi-function switches.

The entire device does feel very light and can easily slide into the travel bag.

port.

Technical indicators.
Size: Approximately 14 inches wide, 9 inches high, and 0.5 inches thick (after folding).
Weight: 1.89 pounds.
Display size: 15.6 inches.
Aspect ratio: 16:9.
Resolution: 1080p or 4K (4K version has been evaluated).
4K resolution: 3840 x 2160.
Brightness: 300 cd/m2.
The contrast ratio is 1200:1.
Shadow space: 100% aRGB.
Rejuvenation rate: 60Hz.
Feedback time: 4ms.
Ports: USB-C input, USB-C PD, HDMI, MicroUSB (x2) for power supply.
Battery: 3000mAh.

Such a slim design is not good for users to a large extent: the 5000mAh battery has actually been replaced by a 3000mAh battery. The previous design claimed to be used for 5 hours, while this design claimed to be used for 3 hours. A problem with the prototype prevented me from assessing the 5-hour claim, but I was able to check it, and it turned out to be only 1 hour and 38 minutes. That is a great sacrifice of work.

However, as eye-catching as the battery-powered display, the fact is that I have been using a battery-powered screen. If I have trouble packing an external monitor, it is because I want to use it throughout the workday and need an external power supply anyway. For me, the eternal use scenario is when I need to continue working on the roadway and stay in the hotel room, so the power is not available.

I am a big fan of widescreen displays, and 16:9 layout is better for me than MacBook Pro 16:10. For people with OCD tendencies, the screen is not perfectly straightened when placed next to the Mac, which would be a bit troublesome, but I quickly forgot to use it. The widescreen ratio is more useful for me.

BladeX widescreen format.

I like the slim approach in terms of leadership and support. The larger chin is low-key, but the logo design is slightly popular. It made me appreciate the extremely delicate MacBook Pro fonts in the bottom structure of the laptop. inclination

The infinite changes are popular. This resort never seemed to consider the authenticity of operating at a desk. The chair is usually uncomfortable and the power socket is not placed properly. Preventing light exposure is one of these challenges, so being able to tilt the display to match you is really easy.

Portable display2

Although it undoubtedly includes some aspects, the top quality of its display does not match the MacBook Pro in terms of specifications. In theory, it has a higher resolution (3840 x 2160), a smaller shadow space (100% aRGB instead of P3 100%), the same contrast (1200:1) and reduced brightness (300 Ni Special, not 500 nits)).

However, in reality these are not important, unless you want to make color-critical changes. It seems that a few years ago, 100% or aRGB was not considered a professional-grade screen. Things are constantly evolving, so professional photographers and videographers will not be satisfied with it now, but for everyone else, the highest quality is really impressive.

Regarding lighting, I found that 7/10 is approximately the correct degree, which is related to the degree I use on the Mac, so from my point of view, the academic maximum brightness level does not reflect real life.

MicroUSB port.

For USB 2.0 ports, MicroUSB is a strange choice, but as far as requirements are concerned, they are basic ports, so you only need the correct cable or adapter to link to the USB gadget, which is a bit strange. My assumption is that companies do this to save space. Directly, I don’t need to connect anything to the screen.

The built-in audio speaker is very small and will touch backwards, which is not ideal for listening to songs. In other words, they not only meet the needs of most informal TV or movie viewing, but also meet the requirements of a two-screen setup. I recommend that you use the integrated MacBook audio speakers.

The HDMI port can be used for cameras. HDMI port

Another benefit is that you can link it directly to an electronic camera, use it as a screen during the entire shooting process, or view it afterwards.

Rates and conclusions.

The price of the kiperline skyine gen 9 screen I evaluated was US$179, while the non-pro 1080p touchscreen model was US$209. The price is mainly the same as other existing portable displays.

Obviously, we should add a typical crowdfunding warning here: not all jobs are provided on time or in other ways, and money may be lost. In short, the company has a good record, ample project funds, and effective prototypes, so the risk should be low.

After spending a lot of time in the hotel in this regard, I can say without a doubt that the second display is the biggest advantage you can play on your own, and the kiperline horizon gen 9 display is also very easy to install Excellent display.

In other words, the Sidecar launched by MACOS Catalina and iPadOS 13 allows you to use your iPad as a wired or wireless display. Especially for users who have a 12.9-inch iPad, it can take you to many places without any additional purchases.

Therefore, whether any external screen is reasonable will depend on whether you have an iPad, the size of the iPad, and how much screen area should be added for you. However, if you are sure to use a dedicated external monitor, BladeX Pro is well worth a look.

LG Present’s OLED TV panels licensed as an Eco-Product by SGS

SEOUL, Korea (Nov. 12, 2020)– LG Show, the globe’s leading innovator of display technologies, announced today that its OLED TV panels have received Eco-Product certification from SGS, a Swiss-based international leader in inspection, confirmation, testing, and also an accreditation.

Amidst expanding interest in the interior setting because of raised stay-at-home tasks amid COVID-19, OLED TV panels have actually been identified as eco-friendly products with reduced exhausts of unsafe materials. They had also currently been accredited for being exceptionally easy on the eye.

Having actually reviewed the overall environmental elements of OLED TV panels, SGS located their ecological friendliness to be specifically noteworthy in three groups covering the lowering of indoor air pollutants, the decrease of unsafe materials, as well as high recyclability.

According to the examination results, OLED TV panels’ discharges of overall unstable natural substances (VOCs) were more than 50% less than those of LCD TV panels. VOCs are connected with a variety of health risks and are a well-known reason for “unwell building syndrome.” As they are often launched by plastics, LCD Televisions discharge more VOCs because they utilize extra plastic-based sheets and also parts for their backlights, whereas OLED’s self-luminous Portable Monitors screen innovation calls for no backlight.

Furthermore, unlike some high-end LCD items, OLED TELEVISION panels do not use any type of parts having hazardous materials such as cadmium as well as indium phosphide, which are Team 1 as well as Team 2 health hazards specifically as identified by the International Agency for Research Study on Cancer under the World Health Company. OLED TV panels also include excellent source effectiveness and also reusing prices due to the fact that they call for fewer components than their LCD equivalents.

” As interior TV watching time rises due to COVID-19, passion in TELEVISION items that are both comfy for visitors’ eyes as well as green is also rising,” stated Dr. Oh Chang-ho, Exec Vice President as well as Head of TELEVISION Organization System at LG Present. “OLED is the best TV modern technology in the COVID-19 age, thinking about that it not just takes into account outstanding picture high quality but additionally wellness as well as the setting.”

Meanwhile, LG Show is focusing on establishing and broadening its manufacturing of environmentally friendly items. By presenting its own Eco Index evaluation standards, the firm has been making efforts from the product growth stage to review and improve its use of recycled materials, lower its energy usage, and minimize its use of unsafe compounds. It has recently been minimizing product packaging product use by recycling OLED panel product packaging.

Naked eye 3D! The world’s first ultra-thin full-color interactive holographic video display comes out

In sci-fi movies, we often see such scenes: on a large screen, 3D objects (or people) that move like ghosts “float” in front of our eyes, lifelike and vivid, we can from all angles See them.

In real life, we can also achieve similar photographic effects, which involves a photographic technique called holography.
In 1947, Dennis Gabor, a British Hungarian physicist, invented the holographic technology, and he won the 1971 Nobel Prize in Physics for this. Since its birth, holography has a history of nearly 70 years.

In 2018, the American camera company RED launched the world’s first holographic projection smartphone; in 2019, South Korea’s Samsung company issued a holographic projection patent. The information is presented in the air through holographic projection, with a full sense of science and technology.
However, because traditional holographic video displays have problems such as narrow viewing angles of optical devices, huge optical systems required and powerful computing capabilities, holographic dynamic video has not yet been widely used in commercial fields.

Recently, a study published in the journal Nature Communications proposed an ultra-thin interactive holographic display that allows viewers to watch high-resolution 3D videos from multiple angles. Let the holographic video display better integrate into mobile devices.

The researchers used a special background light and light swing mechanism to increase the viewing angle of 3D video by 30 times and realized an ultra-thin interactive holographic display design with a total thickness of less than 10 cm, and successfully projected a full screen that can be viewed from multiple angles 4K interactive 3D sea turtle swimming video.

Magical holography

Holography refers to a method of creating unique photographic images without using a lens. The photographic record of this image is called a hologram. The word Hologram is derived from the Greek word, where “holos” means “whole view” ( whole view), gram means “written” (written).

Ordinary photos record the changes in the intensity of the reflected light from the object, resulting in dark areas where there is less reflected light and bright areas where there is more reflected light. However, holography not only records the intensity of light but also records its phase or the degree of coherence between the wavefronts that make up the reflected light.

The hologram displays the “whole” image of the object in a 3D stereoscopic manner. By recording and reconstructing the light field reflected from the observed object, the depth information of the object is preserved and the light field reflected in multiple directions is preserved.

The holographic image is the same as the distance between the human hand and the camera, which provides natural depth perception, prompting the observer to focus on the object itself instead of the screen.

Holograms are widely used in the fields of art, science, and technology. For example, there are holographic images on our credit cards and ID cards to prevent counterfeiting; in medical imaging, 3D holograms of human organs such as the liver can provide doctors with a more comprehensive perspective; in industrial production, The hologram can be used to check the cracks on the product and perform product quality control; in the field of art, the hologram can also be a 3D pure optical artistic creation space.

Previous studies have shown that the holographic video system is achievable. By using a spatial light phase modulator (SLM) that directly modulates the light wavefront, the hologram can be updated at a video rate. However, using a larger optical system can only produce holograms with vertical parallax.

The wide coverage of 4G and 5G networks allows people to watch videos on smartphones anytime and anywhere. However, to make holographic technology “inhabit” in portable monitors devices and construct a mobile holographic video display (mobile holographic video display), technically, the following obstacles must first be overcome:

  1. The limitation of the space-bandwidth product (SBP) determines the size and viewing angle of the holographic image. The SBP of the currently available spatial light phase modulator is usually several hundred times smaller than the SBP of the static holographic medium, and only small size Or a dynamic hologram with a narrow viewing angle.
  2. To produce a large coherent backlight, complex optical components and considerable space are required to manipulate the light. However, it is difficult for the current commercial flat panel displays to meet the requirements of realizing holographic displays in thinness.
  3. Calculating holograms in real-time usually requires a huge computational cost, and with the increase of SBP, the amount of calculation will also increase. After algorithm optimization, cluster processors or high-performance parallel processing systems are still needed to calculate high-quality holograms at the video frame rate.

Dynamic hologram with the largest viewing angle ever

This research demonstrates for the first time a real-time interactive ultra-thin holographic video display. By introducing a steering backlight unit (S-BLU) composed of a coherent BLU (C-BLU) and a beam deflector (BD), the effective SBP is increased than the original value. By 30 times, a dynamic hologram with the largest viewing angle in history is realized.

Optical architecture and key components: a. The optical architecture consists of a beam deflector, a coherent-backlight unit, a geometric phase lens, and a spatial light modulator; b. The principle of the beam deflector, it optically guides the transmitted light like a prism: the angular resolution of the vertical and horizontal phase array guided light is 0.02, when the wavelength is 520nm, the angular resolution of the guided light can reach ~ 15; c. Use waveguide to configure coherent-backlight unit: the first waveguide of red and green light and the second waveguide of blue light are superimposed together to improve the overall efficiency; d. The holographic video processor is implemented on a single FPGA.

S-BLU is a key component to expand the viewing angle of holographic displays. In the traditional beam steering, the maximum steering angle will decrease with the increase of the light source area due to the limitation of light concentration. In the holographic video system designed by this research institute, the researchers successfully solved the problem of light concentration by using the C-BLU waveguide structure.

One disadvantage of the small viewing angle is the long viewing distance. The researchers reduced the viewing distance by 25 times by using a lens with a focal length of 1 m.

For the display of real-time interactive holographic video, it is often necessary to accurately calculate the position of the viewer’s glasses to update the 3D image. The layer method is used to use a large number of two-dimensional inverse fast Fourier transform (2D IFFT) operations to be true. The scene generates high-quality holograms.

In this study, the researchers used a highly parallel architecture and reduced the use of hardware to build a holographic video processor based on IFFT. The processor can calculate two holographic images of the left and right eyes at the same time, and finally combine them into a hologram.

The holographic video processor is constructed with a single-chip FPGA and can generate 3840*2160 pixel binocular holographic color images at a speed of 30 frames per second (fps). Researchers successfully projected a full-screen 4K interactive 3D turtle swimming video that can be viewed from multiple angles.

Gently move the finger to control the keyboard, the turtle in the video can be rotated in any direction, which also proves that the dynamic holographic image can be updated in real-time using the holographic video processor.

The research uses a 10.1-inch ultra-high-definition commercial liquid crystal display to achieve the world’s first ultra-thin full-color holographic video display, and the holographic video processor can be easily embedded in the smartphone application processor.

People often experience visual fatigue after watching movies with 3D glasses. The holographic display screen can create 3D images in space, allowing the audience to watch real objects in multiple dimensions without fatigue. The system calculates the two holographic images of the left and right eyes at the same time in the design, further reducing the viewer’s discomfort in the video.

The researchers said that this research result will strongly promote the development of a mobile holographic video. Perhaps in the near future, scenes from science fiction films may appear in our lives. Take out our smartphones and a 3D holographic video can be easily staged
