Overview

LMG7524RPFC is mature KOE 4.7-inch QVGA monochrome FSTN industrial graphic LCD module, mass pre-installed on small automation equipment operation panels and desktop portable test instruments.100 cd/m² moderate brightness meets indoor workshop, office and laboratory lighting environments. Negative black-on-white high contrast display delivers clear multi-line equipment parameter tables, real-time waveform curves and fault alarm text, suitable for long-time static data monitoring.


12Pin 4-bit parallel MCU signal features stable anti-electromagnetic interference performance, normal image output in light dust workshop environments, fully compatible with mainstream industrial single-chip microcomputer, ARM and PLC control mainboards. Single edge detachable CCFL lamp design allows users to replace aging lamp tubes alone instead of the whole LCD module, effectively reducing on-site maintenance costs. Compact thin aluminum frame saves internal space of small embedded control cabinets and portable field testers.

FAQ

Q1: Does LMG7524RPFC need an external CCFL inverter?

A1: Yes. There is no onboard single-lamp CCFL high voltage boost IC. Matched single-channel CCFL high voltage inverter is mandatory to light up the backlight; WLED constant current drivers cannot substitute without circuit refitting.

Q2: What controller IC is integrated inside this LCD module?

A2: Built-in dedicated monochrome graphic controller supporting standard 4-bit parallel MCU read/write communication, rich mature industrial driver codes available.

Q3: What viewing direction is optimized for this FSTN negative screen?

A3: Optimal viewing angle is 12 o’clock (top viewing), best read effect when viewed from above the screen.

Q4: Can LMG7520RPFC directly replace LMG7524RPFC?

A4: Mechanical outline, mounting holes and 12Pin FPC pinout are fully consistent; verify CCFL electrical parameters and display timing before plug-and-play installation.

Q5: Does the LCM come with touch panel as standard?

A5: Bare LCD module only without touch sensor layer. Separate matched 4.7-inch narrow-strip 4-wire resistive touch digitizer needs optical bonding to form touch industrial HMI assembly.

Q6: Are modules available in stock and ready for shipment?

A6: Yes, brand new original Grade A KOE industrial monochrome modules are in warehouse. Shipment within 1–3 working days after order confirmation, every unit completes full pixel and backlight uniformity inspection before delivery

Questions & Answers
Ask a Question >
Q:
What does 84 PPI pixel density mean? Is the display quality sharp?
A:
84 PPI means there are 84 pixels per inch. For a small 4.7-inch screen, this is a relatively low pixel density. It is suitable for displaying text, icons, and simple graphical interfaces, but not sufficient for very detailed images or very small fonts. Its clarity is adequate for basic information display in many industrial and application scenarios.
Q:
In which devices or fields is this display commonly used?
A:
Due to its moderate 4.7-inch QVGA specification and the reliability of FSTN, it is commonly found in industrial control systems, handheld instruments, medical devices, portable POS terminals, and control panels for home appliances that do not require full-color display.
Q:
What is the interface type of this LCM module? Is it easy to drive?
A:
The "LCM" in the product name stands for Liquid Crystal Module, which means it has an integrated controller. The specific interface type (such as parallel RGB, SPI, MCU interface) needs to be confirmed by consulting the detailed datasheet for LMG7524RPFC. For engineers, driving it is a standardized process once connected according to the datasheet.
Q:
What type of LCD technology does it use? What are the characteristics of FSTN?
A:
It uses FSTN-LCD technology. FSTN (Film-compensated Super Twisted Nematic) is a passive-matrix display technology. Compared to original TN and STN, it offers higher contrast, better viewing angles, and sharper images, typically presenting a blue-on-white or black-on-gray appearance.
Q:
What are the basic resolution and size of this display?
A:
This display has a 4.7-inch screen size with a resolution of 320x240 pixels, which is the QVGA standard.
