Q1: For which TFT-LCD screens and devices is the HXD-1823L LED backlight driver board primarily designed?
A: HXD-1823L LED driver board is specifically designed for small-to-medium-sized LCD display and is perfectly compatible with LCD screens ranging from 10.1 inches to 24 inches. In industrial applications, it is widely used in electronic devices requiring highly stable backlight driver, such as digital signage displays, industrial LCD display monitors, industrial touch screen all-in-one computers, laptops, and automotive LCD display modules.
Q2: What are the input and output electrical specifications of HXD-1823L backlight driver board?
A: HXD-1823L uses a standard 12V DC input and has a maximum output power of 12W. Its output voltage ranges from 35V to 70V DC and automatically adjusts according to the backlight load of the connected LCD screen.
Q3: Our LED backlight module strips require a current of 260mA. Can the HXD-1823L be used? Is customization available?
A: Yes, it can be used. Although the default total output current specification for HXD-1823L is 200mA–220mA, as a direct manufacturer of LCD backlight driver boards, our products offer exceptional flexibility. If you have specific current or voltage customization requirements, please provide your LCD panel specifications when submitting an inquiry.
Q4: What dimming methods does HXD-1823L LED driver board support?
A: HXD-1823L supports wide-range DC dimming. Its dimming control voltage logic is as follows: 0V corresponds to maximum backlight brightness, and 5V corresponds to minimum backlight brightness. Engineers can smoothly control the display brightness of industrial-grade LCD screens by adjusting the DC voltage (0–5V) applied to this pin.
Q5: How does this industrial-grade backlight driver board perform in terms of temperature resistance?
A: Hengxinda has fully considered the extreme conditions of industrial control environments during R&D and production. HXD-1823L utilizes industrial-grade wide-temperature components, with operating and storage temperatures ranging from -20°C to +70°C, and operating humidity support from 10% to 95% RH.
