Since Samsung’s Galaxy S8 and Apple’s iPhone X launch, smartphones with the Home button removed have become a trend in the smartphone market.

Due to the nature of smartphones that cannot grow indefinitely, display sizes with a large proportion within limited smartphone sizes are directly related to the competitiveness of smartphone set makers.

Samsung’s Galaxy S10, which was recently released, attracted great attention with its flexible OLED with HIAA (hole in active area) technology. Notch or HIAA designs, however, can still interfere with video viewing and gaming because camera lenses occupy a small portion of the display.

That is why a number of panel makers are developing under display camera technology for a full-screen display.

Under display camera technology allows the front camera to be placed behind the display for a full-screen display. Oppo unveiled the first smartphone with the technology at MWC China 2019, and BOE and Visionox also anticipated that under-display cameras will become the next trend in smartphones at CIOC 2019.

It is expected that screen, camera module, and algorithmic technologies will all be specially designed to implement under display camera technology. Specifically, the technology to make the pixel near the camera at low resolution to secure transmittance, to mount a CMOS image sensor of a larger pixel size than the existing, and to apply algorithm technology to improve the picture quality.

The trend of full-screen smartphones, which began in 2017, is paying attention to whether full-screen smartphones will bloom with the technology of under-display cameras since 2020.

News about when, where, what size of new investments emerge from Samsung display who leads Recent Small and Medium-sized OLED Market and LG display who leads large OLED market should come true are continuously main news in Display industry. In the middle, Maybe, publics who are invovled in industry, are interested in watching when will China’s panel companies who are processing on construction of flexible OLED line supported by government between Korea narrows the technology gaps.

The Hi-Tech Fair, which celebrates its 19th anniversary this year, is a representative event showing how much China is interested in the IT industry.
Hi-Tech Fair held in Shenzhen, China from November 16th to 19th exhibits almost all fields relevant to IT industry. Communication with Display is a key point to increase importance of IT industry and these two field is developing by complex connecting with another field.

Exhibition include total 9 hall and the newest technology such as Smart cities, robots, aviation, telecommunications, home appliances, games, and other technologies that connect with IT can be seen in that area. Among them,  one that stick out in 1 Hall is Visionox which is large panel company in China, many people are gather together to watch China’s Display Panel technology.

Current smart phone display’s trends are a bezel-less design that maximizes the screen by minimizing the bezel and a curved design represented by the Galaxy Edge series. In this exhibition, Visionox showed a the bezel-less design smartphone which applied rigid OLED and a curved design smartphone which applied flexible OLED having 8R bending radius.

According to officials, disclosed curved display is going to apply to smartphone which will launched in market earlier in 2018. So, this process is currently making decision about supplying with china’s smartphone company. In addition, a variety of flexible displays being developed for future foldable and rollable applications have been on display.

On the other side in Hall, Royole, who manufactures and sells VR devices for China’s leading OLED applications, exhibited flexible sensors with VR device “Noon” Also, they did not exhibit their technology, they disclose a very thin flexible display of 0.01mm through wathcing a video and keep delivering message about continous Display technology development. Also, we can see the various forms and functions of display panel is applied to electrical instruments such as car, robot in many booths. Among them, OLED is expected to continue to grow in significance of IT industry in the future due to its wide range of applications and its technical strengths such as design excellence, thin panel and high resolution.

Galaxy Note 7 records high peak brightness of 1,048 nits

Galaxy Note 7 Records High Peak Brightness of 1,048 nit

DisplayMate Technologies, the leading evaluator of video screens, announced the results of a new series of comprehensive lab tests on the Galaxy Note 7 ’s display.

As the first smartphone to incorporate High Dynamic Range(HDR) technology for mobile video streaming, the Galaxy Note7 provides a cinema-like viewing experience. HDR, the newest performance enhancement feature developed for the latest 4K Ultra HDTVs, expands the color, contrast and brightness of video content through special image processing.

To display the latest high-end video content, the Galaxy Note7 was equipped with the newest standard Wide Color Gamut called DCI-P3 for Digital Cinema Initiative. The measured color gamut of the AMOLED Cinema screen mode is a very accurate 97 percent of the standard DCI-P3 color gamut. It also received a very accurate Absolute Color Accuracy measurement of 2.8 JNCD.

The Galaxy Note7 boasts a record high peak brightness (automatic brightness) of 1,048 nits in high ambient light conditions and a screen reflectance level of 4.6 percent. This means that the screen of the Galaxy Note7 can easily be viewed or read, even under relatively high ambient lighting, such as bright sunlight, which washes out the image color saturation and contrast, decreasing picture quality.

In line with its automatic brightness improvements, the Galaxy Note7 received praise from DisplayMate for being the first of its kind to incorporate a second, rear ambient light sensor. This sensor measures surrounding ambient light and then uses the measured value, along with that of the front ambient light sensor, to alter the display brightness accordingly. The additional sensor helps the device to obtain an accurate reading of the true ambient light level, even when the phone is held in the user’s shadow.

DisplayMate also made note of the Galaxy Note7’s new Blue Light Filter that allows the user to adjust and reduce the amount of blue light from the display for better night viewing, “which some recent research indicates can affect how well users sleep afterwards.”

Featuring curved screen OLED display, the Galaxy Note7 will be available for purchase starting August 19.
