SSD1926QL9 schematic symbol
Audio/video entertainment systems are a must in modern day cars. These A/V systems are different from home entertainment systems because of automotive standards and the compact space. These Audio/Video systems are essentially embedded systems which require image and audio processing.
What is SSD1926QL9？
The SSD1926QL9 is an image processor specially designed for automotive applications by Solomon Systech. The image files are saved in an SD/MMC card in JPEG format. The SSD1926QL9 retrieves the JPEG image files from the card and displays the image on the LCD. A number of different types of LCD screens are supported including STN, CSTN, and TFT. The SSD1926QL9 offers 2D graphics acceleration features such as virtual display, cursor display, image rotation, BitBLT, color fill, and color expansion. The SSD1926QL9 can be interfaced seamlessly with almost all the popular microcontrollers in the handheld device market. The image processor requires only a single clock source. The SSD1926QL9 features advanced power management system which ensures low power consumption.
