At the beginning of 2017, due to the combination of crude oil prices, raw material shortages and other comprehensive factors, a number of chemical plants at home and abroad competed for price increases, setting off an upsurge of price increases. DuPont announced that it will increase the price of Delrin and Zytel nylon products since February 15, 2017. Increases: Delrin: USD0.25/KG Zytel: USD0.3/KG EMS-GRIVORY announced that it will increase the prices of PA6 and PA66 products from February 1. Increases: Grilamid L: RMB1.5/KG Grilamid TR: RMB2.0/KG Grivory GV: RMB2.0/KG Grivory HT: RMB1.5/KG Grilon:>RMB3.5/kg Sabic announced that it will increase PC and ABS prices. Since February 13, 2017, the prices of NORYL and Co-polymer LEXAN products have been increased by RMB2/KG. Since February 13, 2017, PC, PC/ABS, PBT and other prices have been raised. Increases: LEXAN: USD0.25/KG LEXAN COPOLYMER, NORYL: USD0.3/kg CYCOLOY, CYCOLAC, GELOY: USD0.2/KG VALOX, XENOY: USD0.15/KG BASF announced that it will raise prices for PA6, PA66 and POM from January 15, 2017. Increases: PA6: USD200/TON PA66: USD300/TON POM: USD150/TON DSM announced that it will raise prices of PA6 and PA66 from January 15, 2017, which will increase by USD180/ton. Japan Polyplastics announced that it will increase POM POM prices from February 6, 2017. Increases: RMB: RMB0.8/KG USD: USD0.1/KG Taiwan Rubber announced that from January 16, 2017, all products will be price-adjusted, and the increase will be about 20% to 30%. Changchun Chemical announced on February 7, 2017 that it will increase the prices of PA6 and PA66. Increases: PA6: RMB2.5/KG PA66: RMB4.0/KG Huafeng raised the price of TPU products, an increase of 2000-3000/ton
OSD, short for On Screen Display, is used On CRT/LCD displays to produce special glyphs or graphics On the Screen of the Display to give the user information.
In CRT/ LCD display, the working principle is to generate a complete picture control by horizontal and vertical synchronization signals. The external environment can generate image signals at appropriate points in time to generate images on the screen.
TTL (transistor-transistor Logic) is a transistor-transistor Logic in which the TTL level signal is generated by a TTL device. TTL device is a kind of digital integrated circuit. It is made by bipolar process and has the characteristics of high speed, low power consumption and many varieties.
TTL Interface is an interface for data transmission in parallel mode. When using this interface, it is not necessary to use special interface circuits at the driver board end and the Lcd Panel end, but the TTL data signal output by the driver board main control chip is directly transmitted to the LCD panel input interface through the cable. Due to the high voltage of TTL interface signal, many connections and long transmission cables, the anti-interference ability of the circuit is relatively poor, and electromagnetic interference (EMI) is easy to occur. In practical applications, TTL interface circuits are often used to drive small size (below 15in) or low resolution LCD panels. The TTL maximum pixel clock is only 28MHz.
TTL is the only signal that can be recognized by TFT-LCD when the signal is emitted. The early digital processing chips were all TTL, that is, RGB is directly output to TFT-LCD.
