Device Configuration
To improve performance under different applications, first configure some key settings. Select the
DEVICE
CONFIGURATION
button to show the detail setting slide, which is illustrated in
. Maximum current
(MC) is set here. If a high maximum current is set, an external VLED supply is recommended. The
Data Refresh
Mode
settings determine whether a SYNC signal is required to synchronize the PWM change for every LED dot.
The
Max Scan Lines
controls select how many scan lines are active. For more information on the functions for
other settings, see the
LP5860 11 × 18 LED Matrix Driver with 8-bit Analog and 8-, 16-bit PWM Dimming Data
.
When evaluating matrix-issue free performance, de-ghosting and low brightness compensation are configured
here.

Custom LED Setting
Before setting color and brightness for RGB LED, one or multiple LEDs (Shift + select for multiple LED
selections) must first be selected. In the
CUSTOM
tag, set the color in color selector on the right side, see
. Brightness is used to adjust the PWM for all 3 dots in one RGB LED. For some high requirement
applications, dot current can adjust white balance for every RGB LED.
