Abstract
Aiming at the problem of CPLD LCD controller functions simple and SED1335 LCD controller produce a snowflakephenomenon,this paper proposes a system design based on single-chip W78E516B and LCD controller SID13700.The design has simple circuit structure and high universality,and it has been successfully used in products.A large number of products testing show that the display system has merits of high display speed,complex function,stable performance,etc.
