The dimension parameter diagram includes parameters: appearance size, visible area size, pin size and spacing, thickness, material, voltage, positive and negative display, full or semi-transparent or reflective, com number and bias ratio, operating temperature and storage temperature, viewing angle, and display content. None of these can be missing. Truth table: This is the code used when writing programs. After getting the drawing, you must check it carefully to see if the pen segment is divided incorrectly. If you don't find it in time, it will be troublesome if you find an error later. Most of them need to be re-molded.
Wiring diagram: Most customers may not understand it, they are just lines, but it doesn't matter, you just need to confirm that there is no problem with the truth table part, and leave the rest to the designer to check. Display effect diagram: It is the segment code screen in full display state. The inspection is clear at a glance, what colors are there, and how many content segments there are.
