graphic lcd display module is widely used

graphic lcd display module is a very important part, it is widely used, easy to operate, easy to debug. However, the single-chip display Chinese characters there are several problems. First, the limited MCU resources, we can not show too many characters to consume resources; secondly, Chinese characters read is stored relatively cumbersome, inconvenient to use; and third, by dot matrix characters are displayed, often written in a different way with LCD , which was to be converted and adjusted. It is worth noting that the microcontroller-based character display can not be achieved on the character LCD. Use Graphic lcd modules has many advantages, not only can display Chinese characters, and characters can be dynamically moved up and down scrolling, real Characters and now form a mixed display, while low power consumption.
