FAQ

Q1: Does LM64P839 include CCFL inverter?

A1: No, the module only reserves CCFL wiring terminals. An external single-channel CCFL high voltage inverter is required to light the backlight tube.

Q2: Can LM64P83L replace LM64P839 directly?

A2: Mechanical outline, mounting holes and 15Pin pin definition are fully consistent, plug-and-play replacement, no program modification needed.

Q3: What power supply does this panel need?

A3: Dual power supply: +5V logic power and -18.9V LCD driving negative bias voltage, both voltages must be stable.

Q4: Is this a color TFT screen?

A4: No, it is monochrome FSTN passive matrix graphic LCD, only black-and-white gray-scale display, no color rendering function.

Q5: Does the module have touch screen?

A5: Bare LCD display module without touch digitizer; resistive touch glass can be bonded additionally for customization.

Where can I find the detailed technical specifications (datasheet) for the LM64P839?

It is recommended to find the datasheet through the following channels: 1. Contact your display supplier or manufacturer directly to request it. 2. Search for the model "LM64P839" on the manufacturer's official website. 3. Search for this model on some electronic component datasheet aggregator websites.

What are the typical applications or fields for this display?

This 9.4-inch VGA display is commonly found in industrial control equipment, Human-Machine Interfaces (HMI), medical instruments, portable devices, test and measurement tools, and some older car displays or POS systems.

How can I drive this screen? Is it compatible with Raspberry Pi or Arduino?

Driving this screen directly usually requires a dedicated LCD driver board (or adapter board). It cannot be connected directly to the GPIO pins of a Raspberry Pi or Arduino. You need to purchase or make a corresponding driver board based on the screen's interface (see Q2), which then connects to your host device via HDMI, VGA, or a ribbon cable.

What interface does the LM64P839 LCD module use? Is it LVDS, RGB, or something else?

The specific interface type for the LM64P839 module needs to be confirmed by checking its datasheet. However, for displays of this resolution and size, common interfaces include parallel RGB, LVDS, or MCU interface. You need to select the appropriate model based on the output signal of your main control board.

What is the resolution of this 9.4-inch display? How is the clarity?

This display has a resolution of 640 (H) x 480 (V) pixels, commonly known as VGA. For a 9.4-inch screen size, the pixel density (PPI) is relatively low, resulting in a basic level of clarity. It is suitable for industrial applications or displaying static information where high definition is not a primary requirement.
