1. Graphene make plain paper a flexible Electronic paper is not just a dream;
Recently, the Turkish bill deakin university researchers will a common printing paper sandwiched between two layers of graphene membrane (composed of multilayer graphene), make it into a flexible electronic display. They will also be graphene configuration into multiple pixel patterns, the paper folded into a three-dimensional shape, in the above printed color design, show the different for technology of another kind of effect.
According to the American association of electrical and electronics engineers (IEEE) "spectrum" web site reported recently in the flexible display, graphene itself has a variety of purposes, such as a replacement for another scarce material indium tin oxide (ITO, a control display pixels transparent conductor), also can be used in the display floor as electrodes.
Researchers published in the journal photonics paper, according to the current optoelectronic equipment to make paper also has the very big challenge, because the paper surface rough, incompatible with optical materials. And they are graphene as an optical medium electrical configuration, graphene by giving paper applied bias voltage, triggering graphene ions between the layers, make its light absorption sex change, from transparent black or black and transparent. , the authors of the paper KeSiKun can kappa, said, this system can be used as a framework, make ordinary printing paper photoelectric display.
They use chemical vapor deposition method in the metal surface grow graphene, erosion to metal in the water after leaving a thin layer of graphene membrane, and then put the paper into the water, the graphene film transferred to paper. In the experiments, the display from transparent to black is less than half a second, and out of the darkness to transparent to 4 seconds, the signal system is more suitable for do not need to image transform, but compared with the usually show indicator, the refresh rate is too slow.
Can kappa, 'says previous development based on electrophoretic particle movement, cause the color dye and liquid electricity principle of the technology such as wet, also can realize the effect of electronic paper, has great potential in the field of consumer electronics, but these technology and traditional typed made of cellulose are incompatible. Their development is a kind of common printing paper on electricity display information display.
, according to researchers plan to further develop a fully functional electronic paper, there are pixels and integrated driving circuit, and hope that the technology can also be used in roll shaft manufacturing process. Science and technology journal
2. Quantum dots technology by leaps and bounds Printing display to fall to the ground;
On July 22, TCL in zhejiang province held a grand "scientists face to face, quantum dots display technology science forum", zhejiang university, quantum dots, a senior expert professor peng smile just, with representatives from all over the country more than 100 media, face-to-face quantum dot display technology present situation and future prospect are discussed.
Peng smile just dialogue one hundred big media,
For quantum dot radically
Peng laugh just introduced, semiconductor nanocrystals, quantum dots are solution only need to change the size of quantum dots, you can bring up the need to color, color purity is very high, and don't need to worry about life.
Competition of quantum dots and OLED, peng smile just said: "the OLED with birth defects, quantum dots more prospects." OLED TV is currently on the market through the way of preparation of white light OLED production, there are color reduction, increasing energy consumption, high prices, and other issues.
And is a concern for quantum dots "containing cadmium" problem, peng laugh just said, TCL quantum dots TV of cadmium content is very low, the harm to human body, and even break the TV, cadmium will not leak.
Break the foreign monopoly,
China's grip on the next generation display technology tuyere
Peng laugh just pointed out, according to industry core technology has been in the hands of foreign giants, if China's efforts to unite the quantum dots ready, will break the situation.
Quantum dot display technology consists of photoluminescence and electroluminescence in two stages, at present, TCL, hisense, samsung, and other enterprises have realized the photoluminescence products fall to the ground, and the second phase of the electroluminescent, most likely to be the next generation display technology. Electroluminescent quantum dots (QLED) techniques are very valuable, and China is the pioneer of the world's first echelon QLED technology.
Printing according to age,
We are no longer far away
Quantum dots printed display application is from "lab" to be born. TCL has in quantum dot material synthesis, quantum dot printing device, printing and display technology, G4.5 printing platform, five most preferred layout G8.5 printing display platform, etc.
On the market at present, TCL launched QUHD quantum dots TV after this year, made a breakthrough in aspects and so on sound quality, take the lead in promoting quantum dots MinYongHua, commercially and marketization. Publicly for the first time the domestic authority of terry, laboratory test results show that QUHD TV core index than the industry, especially the color gamut coverage is large database 77.9% above the industry average peak, peak brightness, color brightness 26% above the industry average.
Quantum dots are likely to be the only Chinese have the chance to lead a global technology. In the state, enterprises, research and development institutions, under the force of quantum dots display technology is expected to take the lead in China realize new breakthrough in the whole world, the future development of quantum dots space is unthinkable.

3. The Taiwan factory large size panel global share will be increased slightly to 34.8% in 2016;
DIGITIMES Research, investigation and analysis, due to the large size panel to improve the overall supply and demand environment, coupled with samsung display is expected to close the article 1. The quantity is as high as 150000 before the end of the piece of glass substrate of line 7 generations, is beneficial to have many production line 6 and 7.5 generation capacity of Taiwan panel makers to fill the market gap, is expected to bring the positive benefits for Taiwan factory and delivery performance. Estimate the second half of the 2016 Taiwan factory large size (9 inches and above)...
In the second half of the Taiwan factory ship large size panel would is positive global share will be increased slightly to 34.8% in 2016 (1)
Season 3 and 4 sets of 2016 factory large size (9 inches and above) TFT LCD panel shipments forecasts for 61.57 million and 62.44 million respectively, compared with the same period in 2015, 5% and 3.8% increase, according to the overall supply and demand environment improved.
Not sharp. Because the nominal, hon hai, sharp the relationship of strategy alliance.
In the second half competition analysis:
Korea factory to cut investment in South Korea area TFT LCD panel and production capacity, to strengthen the OLED production and market development.
Based on cost considerations, samsung electronics procurement also improve external large size proportion of TFT LCD panel, add factory shipment growth momentum.
Mainland manufacturers in large size TFT LCD investment heat and cooling, and shipment growth speed is slow.

4. Micro LED next generation display technology is expected to mass production in 2018;
2018 Micro LED will be implemented on smart dressing device monitors production, import forecast 2020 smartphones display applications.
Following the traditional LCD, OLED, Micro LED is favored to become the perfect application of a new generation display technology. Recently with Apple (Apple), Sony (Sony) for Micro LED a consortium is becoming more and more attention, has attracted companies have invested, and then accelerate Micro LED commercial production schedule. TrendForce LEDinside's green can cause place according to the latest study, 2018 Micro leds will be implemented on smart dressing device monitors production, import forecast 2020 smartphones display applications.
LEDinside chia-hung chang, an analyst, not only has high brightness, super Micro LED character such as save electricity and reaction speed, more can meet the high PPI (pixel density) and flexible, transparent, such as product design requirements, every breakthrough the traditional LCD, OLED technology limited. Although the Micro LED technology into the display field there are many technical challenges, but production is just around the corner.
Chia-hung chang pointed out that the current Micro LED production levels is the pixel density and the number of pixels trade-offs, so apple and SONY respectively two direction to accelerate the commercial application:
1. The less number of pixels, high PPI
Apple preferred do LED to narrow, high quality, but only do small size display for wearable device, to avoid the cumulative yield is too low, the price can't reach the commercialization levels, have apple longtan factory has experimental lit the 6 inch of Micro LED display. Apple LuxVue through mergers and acquisitions, investment, longtan factory in Taiwan, and the development of the strategy partners have high PPI full-color Micro LED research and development process is more advance, contrast has been selling Apple of the specifications of the Watch, but also can make higher quality.
Chia-hung chang said that at the current technical level and apple's plan, carrying 2018 Micro LED dressing device of possibility is very high, but used to need high picture element such as the iPhone cell phone products again, and so on.
2. The number of pixels, producer prices lower
SONY is preferred to the display screen size bigger, to set goals in remote viewing, due to the need of the LED many, lead to production takes work, can only hope with low PPI (LED size bigger) for indicates rate. Costly Crystal, launched in 2012, after the LED Display, SONY this year because of commercial considerations and adjust the goal, to show stitching Display CLEDIS, overcome the limitation of cost and yield, is expected to cash in 2017 production goal.
5. Panel prices to surge, LCD TV brand factory promotion add variables in the second half of the season
Set micro network news,. 4, 2016 -- TrendForce dramexchange's photoelectric research brand WitsView, according to a report in the second quarter of 2016, the global LCD TV total about 48.68 million units, delivery quarter growth of 1.2%. In the second quarter even if there were issues of sport hyped cargo kinetic energy than expected, combined with Chinese traditional brand factory shipments fell, made the global LCD TV shipments growth is limited.
WitsView research manager Lin could shun said, recent panel prices to surge, Korean and some factory of first-line brand panel to procurement strategy, in order to maintain plant grain or moving rate and ensure the access number of stores, or even to maintain enough panels supply at no cost, a move that could make some brand factory original prepare for Thanksgiving Day promotion at the end of my briefcase panel price and quantity change. Owns the panel factory support of their own brand will be sure to relative advantage in this wave of out of stock, but for good Season to break the sales price of the sprint other first-line brand, this year will face severe challenges.
