智能车液晶XS128_OLED，OLED，即有机发光二极管（Organic Light-Emitting Diode），又称 为有机电激光显示（Organic Electroluminesence Display, OELD）。 因为具备轻薄、省电等特性，因此从 2003 年开始，这种显示设备在 MP3 播放器上得到了广泛应用，而对于同属数码类产品的 DC 与手机，此前只 是在一些展会上展示过采用 OLED 屏幕的工程样品。自 2007 年后，寿命 得到很大提高，具备了许多 LCD 不可比拟的优势。

基于NIOS II的LED屏贪食蛇设计，基于NiosII软核处理器和LED点阵显示屏的贪吃蛇游戏内容是：一条蛇在封闭的围墙里，围墙里随机出现一个食物。玩家通过4个按键控制蛇上下左右移动，且蛇只能沿着头运动的轨迹移动。蛇头撞到食物，则食物被吃掉，蛇身体增长一节，同时记1分，又出现食物，等待蛇通过玩家的控制来吃掉，如果蛇头在移动中出界或咬到自己的身体则游戏结束，并且加入了一些附加功能如蛇身加速，选择难度，开关机屏幕画面的优化等一系列功能，使游戏更具可玩性。(NIOS II LED screen Snake design, NiosII based soft-core processor and LED dot matrix display Snake game content is: a snake in a closed fence, the fence was a random food. Players control a snake through 4 keys to move around, and the head of the snake can move along the track movement. Snakeheads hit the food, the food is eaten, the snake grow body section, but remember one point, appeared foods, through the player controls a snake waiting to eat, if snakeheads bite out of bounds or move their bodies in the game end, and added some additional features such as snake acceleration, choose the difficulty to optimize switching machine screen and a series of features that make the game more playable.)
