In vehicles the manufacturer provide analog meter for displaying the parameters like speed, temperature, fuel level and so on. Analog meters lack in accuracy, calibration, precision, robustness and shot life time when compared with the digital systems. So here we use digital display called TFT (thin film transistor) which is used to display the parameters of the vehicle in graphical and in data form. When interfacing more sensors the microcontroller needs CAN (Controller Area Network) bus. So PIC controller with in-built CAN transmitter and receiver which is for transmission and reception of data between the nodes. For a better performance of the CAN bus we use dynamic priority protocol. This can improve the real time transmission of data especially data with low priority. By using CAN bus we can reduce the complexity of the connection present in the vehicle. TFT display has many advantages such as TFT monitors produce less heat and radiation making a very crisp image. The image displayed will be of less glair/flicker with much finer quality-everything is much clear and colors are more varied and defined.
