UART display module

The RS232 LCD module is a kind of serial display module that based on EIA-RS-232 standard. This standard is widely used in serial communication, like PC peripheral equipments, such as teletype and modem. LCD module that works in UART pattern is also called UART LCD module. That is to say, every serial LCD module and TFT LCM with RS232 compatible is a UART LCD. Its instinct advantage lies in no synchronization signal transferring by another line, which is suitable for kinds of application and systems that require low power consumption and Simplified circuits.
However, the synchronization signal is added before and after data transmitting. This may cause a slice delay of response potentially. LCD module manufacturers have developed several reliable technologies to assure its real-time performance. A mainstream technology is based on utilizing the built-in MCU, by using a simple but powerful command-set. As a classic solution of time-space and time-processing swap, this lead to the balance of developing time and cost. Some Graphic lcd module companies in China have already advanced an approach to settle this down. By introducing intelligence into UART TFT Display Module, developers can finish their design within a predictable time period, by figuring out specified program to send the fixed commands to LCD display module.
