Recent developments in science and technology Recently , the Dutch research institute HolstCentre, the Belgian Institute of Microelectronics Research (IMEC) and Centrefor Microsystems Technology (CMST) , a research institute funded by IMEC in Ghent University in Belgium, announced the development of LED-based, color display Flexible display. According to reports, the display is an active matrix type display using the compound InGaZnOTFT, which can be used on cloth and can be washed. In addition, Panasonic also participated in the development of the display.
The number of pixels of the display screen is 32×32×RGB, and the fineness (pixel density) is 13 ppi, that is, the pixel pitch is about 2 mm, and the average luminance exceeds 200 cd/m 2 . The driving voltage is 7V.
The most important part of this display is the use of serpentine copper wiring for the wiring between the connected pixels, thereby obtaining bending and drawing resistance and stretchability. Serpentine cabling has also been used previously, and the research lab of Professor John Rogers at the University of Illinois used it on sensor terminals. But for the first time for the display.
The substrate material is a polyimide resin, and the sealing material uses rubber and can be directly attached to the cloth for washing. According to reports, the manufacturing technology of the display uses mass production technology and can be quickly realized.
By the way, in the screen-associated society "SID 2015" held in June, related papers of the previous generation of development products of this display were published, and Matsushita's researchers were the first authors. At that time, the development product had a pixel count of 45×80×RGB, a pixel density of 8.5 ppi (3 mm pitch), a luminance of 30 cd/m 2 , and a driving voltage of 5 V. It was a passive matrix display.

It is convenient to adjust the trolley according to the construction of the variable cross-section second lining of the subway tunnel. According to the change of the subway tunnel section, the width of the construction trolley is randomly adjusted to adapt to the subway tunnel section. The construction requirements are changed. The adjustment of the trolley Convenient and fast, with few operators, low potential risk, low cost and high work efficiency.
