Abstract

The hardware and software design of LED display screen systems requires engineers to understand design requirements of the LED display screen and to make sure the driver performance can satisfy these requirements. There are many LED display design parameters that can confuse designers when configuring the LED driver.

This application note presents an emerging LED display end equipment example, an LED cinema screen, to help designers better understand and design the LED display screen system. The LED cinema screen example has a 1920-Hz to 7680-Hz refresh rate, 60/120-Hz frame rate, and 14-bits to 16-bits PWM resolution. This application note shows how to calculate configuration parameters step-by-step based on TI’s latest Common Cathode Matrix LED Display Driver, the TLC6983.
