The proposed LCD sketch and instructions sent to at least three suppliers

1. Consider what needs alphanumeric LCD useful information and customization required in combination with a custom icon is displayed on the custom LCD.
2. Learn LCD need to work environment. Operating voltage and temperature will greatly affect the LCD contrast, and may limit the LCD type can be used.
3. Determine the number of Character LCD Modules segments required to achieve the necessary display on the LCD, and the reference matrix LCD PIC microcontroller to select the appropriate LCDPIC microcontroller.
4. Generate customized LCD sketch / mechanical drawings and written instructions and understand LCD pinout.(Due to the wiring section and the wiring electrode of the common electrode is not a limitation of this plane, and therefore, is preferably accomplished by the display manufacturer pin arrangement.)5. The proposed I2C Lcd Display LCD sketch and instructions sent to at least three suppliers, obtain written quotations to determine pricing, scheduling and quality matters. The total NRE cost, price and installation costs into account. Allow at least two weeks time for the completion of formal mechanical drawings and pin assignments, as well as the revised drawings.6. Request Delivery initial prototype LCD components to ensure proper development of LCD and correct functioning of the target application.Usually set aside four to six weeks time. For final approval mechanical drawings and pin assignments. After the delivery of the initial prototype LCD approval.7.Upon receipt of a prototype LCD, first confirm its function, and then make the final approval and began producing LCD.
