Beijing, China, March 20, 2013 – Dialog Semiconductor (Frankfurt Stock Exchange code: DLG), a provider of highly integrated power management, audio and short-range wireless technology, today announced that the company will enter the touch screen sensor market , Launched SmartWaveTM (part number DA8901) multi-touch integrated circuit (MTICTM). MTIC is the world's first chip used to implement FlatFrog1's widely recognized PSD (planar scattering detection) touch technology and is used in various mass-produced consumer electronic devices. With the help of infrared rays in the protective glass, FlatFrog's PSD touch system can detect and track the multi-touch, gestures, and force of sensing gloves, styluses, and other objects, thereby providing users with a more natural and real touch experience , Its performance exceeds the latest capacitive touch solutions, but the cost is much lower than the latter.
MTIC is suitable for today's notebook computers, all-in-ones, ultrabooks, and monitors, and is optimized for displays from 11 to 36 inches. In addition, it also meets the touch requirements of Microsoft Windows 8 and Intel Ultrabook.
MTIC can support up to 40 simultaneous touch operations. It uses FlatFrog's proven PSD touch technology to detect changes in the infrared light injected into the display's protective glass. When the user touches the glass surface, the scattered light will be detected by multiple infrared receivers. The generated signal is received by MTIC, amplified and pre-filtered, and then converted to the digital domain. Then, the system uses the MTIC built-in detection engine based on the ARM® Cortex ™ M0 processor to perform advanced signal processing on these data, and the processing results are used as the basis for providing touch coordinates to the main processor of the device.
One MTIC can directly drive 12 pairs of infrared LEDs / emitters. A typical ultrabook, tablet or all-in-one can be equipped with multiple MTICs in a master-slave configuration to flexibly match screens of different sizes (up to 36 inches). PSD touch technology supports any type of display, and also supports protective glass or protective plastic. Unlike the projected capacitive (procap) touch technology widely used in smartphones and tablets today, because there is no expensive ITO layer to block the light from the display to the eyes, the system can provide an edge-to-edge industrial design (edge-to-edge industrial design) and excellent optical clarity. This also means that there is no need to achieve the same brightness by maintaining a strong screen background light, which can further reduce system power consumption.
Mark Tyndall, vice president of global business development and strategy at Dialog, said: ―DA8901 MTIC will surely become a true game-changer, and it can provide uncompromising points for all kinds of mainstream ultrabooks and many new-generation touch display products. Touch function. Unlike other touch technologies, the system cost of competing technologies increases linearly with screen size. This means that even the lowest-priced mainstream all-in-ones and monitors can enjoy the excellent multi-touch experience brought by the A8901 MTIC.
Tyndall added: ―We are very pleased to work hand in hand with FlatFrog and look forward to continuing to develop this cooperation.
Christer Fåhraeus, co-founder and chairman of the FlatFrog laboratory, added: ―After years of improving our technology, we are proud to cooperate with innovative companies like Dialog. With this optimized mixed-signal integrated circuit, Dialog has pushed our PSD technology into the production consumer electronics market, providing the industry with a lower-cost solution that can replace other touch sensor technologies.
DA89015 is available in 59-pin, 5.7mm x 5.0mm QFN packaging. This product has the characteristics of small size and minimal external materials. It is very suitable for carrying LED transceivers, installed on a thin printed circuit board on the edge of the display, or installed on the lower part of the display to provide a borderless design. The thin design means that the entire system is thinner than the display module and does not increase the thickness of the finished product.
DA8901 MTIC will be listed in the third quarter of 2013.
The tubular oil level gauge is used to judge whether the transformer is short of oil through the color in the observation window by floating the float up and down. Generally, the observation is full of red marks indicating that the transformer tank is short of oil and needs to be replenished; Patrol inspectors of glass tube type oil level gauge can directly see the amount of transformer oil through the height of the oil level line in the glass tube. When the oil level is below - 30 °, oil replenishment is required
This series of products are mainly applicable to oil immersed fully sealed transformers, which are installed on the upper part of the transformer oil tank cover to display the oil level in the oil tank. The oil level is normal when the blue mark appears in the upper window of the oil level gauge, and the oil level is above the tank cover; If the red mark appears, it means that the oil pointer is abnormal, and the oil level is below the tank cover, so it is necessary to add oil properly.
