♦ Two Dimming Methods
HXD-1830L backlight driver board supports two dimming methods as following
• DC Dimming: 0V = Maximum Brightness; 5V = Minimum Brightness
Ideal for: Industrial control systems, Medical equipment, and Traditional LCD monitors
• PWM Dimming
Frequency: 1KHz – 10KHz
Input Voltage: 2V – 5V
Duty Cycle Control
Ideal for: Embedded systems, ARM controllers, Industrial PCs, Digital signage players, and Single-board computers.
This flexibility significantly reduces development time and compatibility concerns.
♦ Designed for LCD Backlight Integration
The HXD-1830L backlight driver board is specifically designed for LED backlight structures used in LCD modules.
Benefits include:
• Stable current regulation
• Consistent backlight brightness
• Reduced LED stress
• Better display uniformity
Suitable for LCD panels ranging from 10.1 inches to 24 inches.
♦ Long and Narrow PCB Design
Many equipment using LCD panel enclosures have limited installation space.
HXD-1830L backlight driver board features a slim PCB layout: Length: 120 mm; Width: 20 mm; Height: 10 mm
The narrow form factor allows easier installation inside: Industrial monitors, Digital signage displays, Medical terminals and Embedded display housings.
