1. Resolution: The number of pixels of the LCD display , such as 800 * 480, 1024 * 600, must be greater than the maximum number of pixels required to display the content of the product..
2. Dimensions: The LCD size must be adapted to the structural size of the product shelf case, such as 5.0", 7.0".
3. Circuit coordination: The selection of the LCD circuit will be directly related to the circuit design of the MPU system. Circuit combination needs to compare the MPU system resources and module circuit characteristics to make comprehensive consideration. Built-in drive LCD display module
, configured with MPU with LCD display drive, such as ARM 9 series. Built-in controller LCD module , and the controller has a variety of part numbers, each of performance has its characteristics, such as Chinese character library, with two-dimensional graphics accelerator, only RAM which with display function, can be suitable for the needs of various MPU systems.
The interface of module and MPU: parallel interface, INTEL8080 and MC6800 sequence; serial interface, SPI 3 / 4 line serial interface, RS 232 interface and I2C bus interface, etc.
Suitable with the MPU system: the power supply voltage of the module is consistent with the module interface signal level, and the working power supply and signal voltage of the module are consistent with the power supply and signal level provided by the MPU system, reducing the level conversion circuit to reduce the signal connection.
Power consumption of the circuit: it is necessary to evaluate whether the MPU system power supply can support the working state current and dormant state current and backlight current of the circuit.
