INTERACTIVE DISPLAY DEVICE AND METHOD FOR LED DISPLAY DRIVER

摘要

An interactive display device and method for an LED display driver. By configuring two paths of parallel triggers (FDE #0, FDE #1) with enable pins (CE), latch control signals (LE, LE', LE'') are used to perform a secondary time sequence displacement and time delaying to be used as clock signals (SCK) to alternately operate and output data display signals (Q0, Q1) input currently to a selector (MUX), and the selector (MUX) takes a result after performing logic and operation on latching control signals (LE, LE'') which are original and subjected to the secondary time sequence displacement as a selection basis and outputs the result, thereby realizing the purpose of being capable of performing stepless segmentation on a data display cycle and realizing the interactive display controlled by a data encoding combination, which can realize the control to a display time width in a data display requirement, so that the stepless segmentation on the display cycle is realized, and a random segmentation interval can be generated according to demands. The interactive display device and method can realize the data encoding combination control, and can improve the refresh rate and grayscale level performance of a display image in a display application.
