Liao Wei-lun, president of AUO's video products business group said that AU Optronics will start shipping 65-85 inch 8K LCD TV Panels in the first half of the year. Digitimes reports. This should mean we will get to see the first TVs based on those panels in the second half of the year.

Liao expects that 8K TVsof 65" and larger will hit an 10% market share in 2020. Therefore AUO will begin volume production of 8K TV panels soon to cash in on the emerging trend, according to Digitimes.

Global sales of 65- and 70-inch display are to grow by 40% and 50% this year compared to 2017. 4K TVs in general is to reach a 40% penetration, a 33"growth over last year, so AUO will focus on these products. Liao expects 4K to establish itself as the standard for 50" and above TVs this year.

Currently the only 8K Consumer TV available is a Sharp 70" that started shipping in September in China, and December in Japan. A sister company to Chinese owned Sharp just opened a gen 10.5 LCD plant that is optimized for 60-75" panel production.

BOE also has plans for 8K panel production this year.

ΔE00 no longer matches human perception in HDR and Wide Color Gamut imagery, so use ΔICTCP instead for these smaller differences in perception.


Abstract:
With the emerging demand for high-dynamic-range (HDR) and wide-color-gamut (WCG) technologies, display and projector manufacturers are racing to extend their color primaries in the cinema and in the home. With these brighter and wider colors, the question is: in calibration, how close is close enough? This answer is increasingly important for both the consumer and professional display/projector market as they balance design trade-offs. With HDR/WCG technology, an increasing issue is that many of the color difference metrics in common use today, such as ΔE00, substantially deviate from human perception and become unreliable for measuring color differences. This causes under and over prediction of color differences and can to lead to sub-optimal design decisions and difficulties during calibration. There is a large amount of perceptual color difference data in the field today, however the majority was collected using reflective surfaces and very little reaches the boundaries of modern display capabilities. To provide a better tool for facilitating design choices, this paper will present a “ground truth” visible color difference dataset. These visual experiments were conducted between luminance levels of 0.1 and 1000 cd/m2 on high dynamic range laser cinema projectors with approximate BT.2100 color primaries. We will present our findings, compare against current metrics, and propose specifying color tolerances using the ΔICTCP metric for HDR and WCG imagery.

Abstract:
As is well-known, colors as they exist in the real world must be adjusted so as to look correct and pleasing when displayed on a television or cinema screen. In color science, the process of converting these “scene-referred” colors to “display-referred” colors is termed “rendering.” The Academy's ACES system is a good example of a set of open-source picture rendering algorithms. In this paper the authors, who both participated in the development of ACES, discuss the pros and cons of various rendering techniques and share the results of their latest work. Specifically we present a method of applying a tone curve that preserves color ratios and has better noise properties than earlier techniques. This algorithm has been successfully used as part of a larger parametric rendering system for HDR display. One of the nice properties of this algorithm is that it has a simple and robust inverse.

In the News / ISE draws in 80,923, 103% rebooked for next year
« Last post by DCI forum on Thu February 15, 2018, 06:30:49 AM »
ISE, or Integrated systems Europe has grown to be the largest international Pro-AV trade show, drawing in 80,923 registrated attendees, only the NAB show in Las Vegas draws a larger crowd, with over 100,000 visitors. And it felt busy with plenty of filled up aisles on the first two days of the show. The visitor number grew 10.3% over last year's show, organisers said.

ISE has seen a tremendous growth from its humble beginnings of occupying merely half a hall in 2005, to 1296 exhibitors (294 new to the show), and 53,000 square meters of exhibit floorspace, thirteen years later.

Over 30% of the total attendees were visiting ISE for the first time, new people to ensure future growth of the show and industry: "a key benchmark for exhibitors in their quest to develop new sales leads", the organisers added in a statement.

The success leads floor space to already be confirmed for ISE 2019 (RAI Amsterdam from 5-8 February 2019) to currently stand at 103% of the total booked for ISE 2018.

Mike Blackman, Integrated Systems Events Managing Director, commented: “It’s been a great show that has delivered on all fronts. I’m delighted to report that visitor numbers and exhibitor satisfaction have both been very high. On behalf of ISE, I’d like to thank all our attendees, exhibitors, partners and our co-owners AVIXA and CEDIA. This combination has made ISE what it is today and ensures that we are able to build on our successes year on year.”

ISE 2018 saw the debut of the World Masters of Projection Mapping competition, a joint venture between the Amsterdam Light Festival, RAI Amsterdam and ISE. The competition saw leading video artists’ project video artworks onto the EYE Filmmuseum in the centre of the city. The competition culminated in Florian and Michael Quistrebert receiving the winner’s award for their artwork Stripes 5 on the last day of the show.

Main themes in technology and business trends included: a growth in IP and the crossover between broadcast and AV; commercially viable virtual, augmented and mixed reality technologies and solutions; the increase of devices for the smart home; the divergence of digital signage with both smart systems and ‘plug and play’ gaining traction; the increase in small pitch LED displays; 4K everywhere; IoT everywhere; the growth of projection mapping; networked audio and the continued progression of the collaboration market.

Panasonic has developed the first 8K Global Shutter Technology on an Organic-Photoconductive-Film CMOS Image Sensor technology image sensor design. The new technology enables 8K high resolution and high picture quality imaging without motion distortion, even in extremely bright scenes.

The technology realizes 8K high-resolution (36M pixels), 60fps framerate, 450k high-saturation electrons and global shutter imaging with sensitivity modulation function simultaneously, using a CMOS image sensor with an organic photoconductive film (OPF). In this OPF CMOS image sensor, the photoelectric-conversion part and the circuit part are independent.

"By utilizing this OPF CMOS image sensor's unique structure, we have been able to newly develop and incorporate high-speed noise cancellation technology and high saturation technology in the circuit part. And, by using this OPF CMOS image sensor's unique sensitivity control function to vary the voltage applied to the OPF, we realize global shutter function. The technology that simultaneously achieves these performances is the industry's first" Panasonic said in an statement.

With the technology, it is possible to capture images at 8K resolution, even in high contrast scenes, such as a field under strong sunlight and shaded spectator seats under a stadium roof. Moreover, by utilizing the global shutter function that enables simultaneous image capture by all pixels, it is expected to be able to capture moving objects instantaneously without distortion, be utilized for multi viewpoint cameras (performing multi-view synchronized imaging using plural cameras) and used in fields requiring high-speed and high-resolution, such as machine vision and ITS monitoring. In addition, conventionally, even in scenes where it was necessary to utilize different ND filters according to capturing conditions, the technology realizes a new electronically-controlled variable ND filter function which enables stepless adjustment of the OPF sensitivity merely by controlling the voltage applied to the OPF.

The new technology has the following advantages.
8K resolution, 60fps framerate, 450k saturation electrons and global shutter function are realized simultaneously.
Switching between high sensitivity mode and high saturation mode is possible using gain switching function.
The ND filter function can be realized steplessly by controlling the voltage applied to the OPF.

This Development is based on the following technologies.
"OPF CMOS image sensor design technology", in that, the photoelectric-conversion part and the circuit part can be designed independently.
"In-pixel capacitive coupled noise cancellation technique" which can suppress pixel reset noise at high speed even at high resolution
"In-pixel gain switching technology" that can achieve high saturation characteristics
"Voltage controlled sensitivity modulation technology" that can adjust the sensitivity by changing the voltage applied to the OPF.

Panasonic provides a number of samples demonstrating the advantages of the new image sensor design with integrated shutter and Neutral Density filter function.

1. "OPF CMOS image sensor design technology", in that, the photoelectric-conversion part and the circuit part can be designed independently.
The OPF CMOS image sensor has a unique structure, in which, the OPF performs a photoelectric conversion and the circuit area performs charge storage and signal readout functions completely independently. Using this OPF CMOS image sensor structure, we developed high-speed noise cancellation technology and high saturation technology in the circuit area which has a large available space. As a result, it is possible to realize simultaneously 8K resolution, 60fps framerate readout, wide dynamic range [4] (by achieving a high saturation level) and global shutter function, which are normally traded off.

2. "In-pixel capacitive coupled noise cancellation technique" which can suppress pixel reset noise at high speed even at high resolution
Because the OPF CMOS image sensor has a structure in which the OPF and the charge storage part are connected by metal plugs, accumulated charges cannot be completely read out. Therefore, there is a problem that it is affected by reset noise at the time of resetting the pixel (signal charge storage node). And, in a high-resolution sensor, such as an 8K sensor, it is necessary to drive large loads exceeding 4000 pixels aligned in the vertical direction at the same time as the time of noise cancellation, and therefore, the long time it takes to suppress noise is a problem. So, we developed a new structure that cancels pixel reset noise at high speed, even when high resolution pixels have to be driven, by using Panasonic's original semiconductor device technology and the newly developed "in-pixel capacitive coupled noise canceller". In this structure, the reset noise is suppressed at high speed by using the negative feedback loop provided for each pixel.

3. "In-pixel gain switching technology" that can achieve high saturation characteristics
In the OPF CMOS image sensor, by incorporating a large capacitor in the circuit part with a large available area, it is possible to realize both high sensitivity mode and high saturation mode with the same pixel structure merely by switching modes from the camera system. In the high sensitivity mode, it is possible to capture data up to a light intensity of 4.5k electrons with high sensitivity. Furthermore, by switching to the high saturation mode, it is possible to capture data up to a light intensity of 450k electrons. In this way, since the high saturation mode can capture up to 10 times the high sensitivity mode, it is possible to clearly display the fine winding structure of the lamp filaments, in which bright part gradation cannot be expressed, because it becomes overexposure in high sensitivity mode, as shown in Fig. 3 (a). Even in a scene with high contrast, such as shown in Fig. 5, from the facial expression of the person in the shadow of the stadium roof to the blue sky and clouds during a mid-summer day, and such as shown in Fig. 6, from the dimly lit room to the sunny garden, it will be possible to capture brilliant images without overexposure or underexposure.

4. "Voltage controlled sensitivity modulation technology" that can adjust the sensitivity by changing the voltage applied to the OPF.
The OPF CMOS image sensor can change the sensitivity of the OPF simply by controlling the voltage applied to the OPF. By utilizing this function, we can realize the following functions which could not be realized with conventional silicon image sensors.

Sensitivity Modulation Example 1: Global shutter function which can capture all pixels simultaneously at 8K resolution
By controlling ON / OFF of the voltage applied to the OPF and controlling the sensitivity of the OPF, we realize the "global shutter function" capable of imaging all pixels at the same time, even driving a large number of pixels like the 8K sensor. By capturing with the global shutter function, as shown in Fig. 3 (b), the letters on the rotating body are read sharply without distortion. In addition, as shown in Fig. 7, even at the time of high speed moving object capturing, such as when driving on a highway or at industrial inspection, capturing without distortion becomes possible.

In the conventional global shutter type silicon image sensor, it is necessary to add new elements such as transfer circuits and charge storage capacitors in order to accumulate charges simultaneously in all pixels. As a result, the area of the photodiode and that of the additional circuits must compete for space, there is a problem that the pixel size cannot be reduced and the amount of saturation electrons cannot be increased. On the other hand, in the OPF CMOS image sensor, since there is no need for additional elements, it is possible to realize small cell, high resolution sensors, and by incorporating large capacitors in the circuit part with a large available area, accurate imaging with no distortion from dark scenes to extremely bright scenes is possible. For example, as shown in Fig. 9, with the OPF CMOS image sensor, when buildings are photographed while panning [5] at high speed, even in scenes with high contrast like a bright sky and dark windows, it is possible to acquire image data maintaining all gradations of the whole area without distortion.

Sensitivity Modulation Example 2: "Electrical ND Filter Technology" which can change sensitivity continuously and steplessly
Conventionally it has been necessary to provide a plurality of ND filters according to photographing conditions and change them many times. On the other hand, in the OPF CMOS image sensor, merely by controlling the voltage applied to the OPF (VITO in Fig. 8) and changing the sensitivity of the OPF to the desired value, it is possible to electrically implement the ND filter function. By using this function, it becomes possible to simplify the photographic equipment and continuously, steplessly control the sensitivity which could not be realized with a conventional silicon sensor. Therefore, the possibility of capturing according to the scene is expanded.

In the future, we will utilize this OPF CMOS image sensor technology in various applications such as broadcasting cameras, surveillance cameras, industrial inspection cameras, automotive cameras, etc., and will contribute to realize high resolution, high speed and high precision imaging and sensing functions.
