Display Module Engineering Guides
Written for the engineer who has to choose a display, not for search engines. Each guide answers one decision - interface, brightness, touch stack, tooling, terms, obsolescence - and backs it with the actual parameters of the 103 fully specified models on this site rather than generic industry figures.
LCD Interfaces Explained: SPI, MCU, RGB, LVDS and MIPI
The interface is the first decision, not the last: it decides whether your processor can drive the panel at all, how many pins the display costs you a...
How Many Nits Does a Sunlight-Readable Display Need?
Short answer: 200-300 cd/m² indoors, 350-450 cd/m² for shaded outdoor or a window-lit factory, and 500 cd/m² or more - or a transflective build - for ...
Capacitive or Resistive Touch, Air Bonding or Optical Bonding
Capacitive touch wins on feel, multi-touch and durability, and it is what most buyers now specify by default. Resistive still beats it in three cases:...
How a Custom LCD Module Is Developed, Step by Step
Most 'custom' display projects are not custom glass at all - they are an existing panel with a different FPC, connector, backlight or touch stack, whi...
LCD Module MOQ, Lead Time and Sample Policy
Samples 5 pcs. Catalogue models 100 pcs. Fully custom tooled glass 1,000 pcs. Production lead time 10-20 days, samples 10-15 days. Payment T/T, L/C, P...
When Your LCD Goes End-of-Life: Finding a Replacement
An EOL notice on a display is not a purchasing problem, it is a re-qualification problem. The fastest route is to define the replacement by what your ...
TN, IPS, VA and STN: Which Glass Mode Should You Specify?
Glass mode decides how the display looks from where the operator actually stands. IPS holds colour and contrast off-axis and is the safe default for a...
Wide-Temperature LCD Modules: Designing for -40 to +85 Celsius
Standard commercial panels stop around 0 °C. Our standard industrial parts run -20 °C to +70 °C and wide-temperature parts -40 °C to +70 °C with stora...
Driver ICs We Use, and Why the Controller Matters to Your Firmware
The driver IC is the part your firmware actually talks to. It sets the initialisation sequence, the command set, the addressing mode and often the max...
FPC, Backlight and PCBA: What Can Be Changed Without New Glass
Most display customisation happens around the glass, not in it. FPC length, pin order and exit direction, connector, backlight brightness and colour, ...
How to Choose an LCD Module in Seven Decisions
Specifying a display is seven decisions, and their order matters more than any single one of them. Size and interface come first because they constrai...
How LCD Modules Are Packed, Protected and Shipped
Display modules are damaged in three ways in transit: static, pressure on the glass, and moisture. Our standard export pack is anti-static bag + foam ...
TFT Shows a White or Blank Screen: a Hardware Checklist
A white screen is usually good news: the backlight works and the panel is powered, but the driver IC never received a valid initialization. A black sc...
ST7789 / GC9A01 / ST7735 Init Problems: Offset, SPI Mode and CS
These three controllers sit behind most small SPI colour displays, and most “my display shows garbage / a shifted image / nothing” threads trace back ...
Buying Display Modules Without a Datasheet: the Real Costs
A three-dollar module with no documentation is a fine way to try an idea and a poor thing to build a product on. The price difference between a market...
Why Your SPI Display Manages 5 fps - and When to Leave SPI
When an SPI screen feels slow, the instinct is to blame the library. Usually the library is fine and the arithmetic was never done: a frame has a fixe...
From Arduino Prototype to Production: the Display Decisions
A prototype built on an Arduino library and a marketplace breakout board is a legitimate engineering artefact - it proved the idea. The jump to produc...
How to Specify a Custom Segment LCD Display
Segment glass is fully custom by definition - there is no catalogue part to point at, only a layout you design and we tool. That makes the specificati...
Smart Serial Display or a Bare TFT with Your Own MCU?
The question is not which display costs less - it is which display plus the engineering time around it costs less, and that answer flips depending on ...
Industrial OLED Lifetime, Burn-In and How to Design Around It
OLED gives up backlight lifetime for contrast, power efficiency at low brightness and a thinner module than any backlit panel on this site. Whether th...
Backlight Lifetime: What '40,000 Hours' Actually Means
A backlight lifetime figure looks like a single fact. It is actually a measurement taken under specific conditions, and the gap between that measureme...
Cover Glass and Surface Treatment: AG, AF, AR and Printing Options
The surface finish on a cover glass changes how a display reads in the real world as much as the panel underneath it does, and it is one of the most c...
HS Code, Duties and Shipping for LCD Display Modules
Classification and duty questions come from import teams, not engineers, and they come after the technical decision is already made - which is exactly...
How to Verify a Shenzhen LCD Display Factory Before You Order
Every supplier's website says the same things - factory direct, quality guaranteed, years of experience. None of that is verifiable by reading it. Wha...
What Is an IPS Display? IPS LCD Modules Explained for Engineers
IPS - in-plane switching - is a way of arranging the liquid crystal in a TFT LCD so the picture barely changes when you look at it from the side. It i...
LCD Image Sticking, Pressure Marks and Mura: Causes and Prevention
Three complaints reach display suppliers more than any others once a product is in the field: a faint ghost of an old screen that will not go away, br...
OEM vs ODM Display Modules: What Changes for the Buyer
In display sourcing the two terms are used loosely, and the difference matters more than the label: it decides who owns the design, what has to be too...
Transmissive, Reflective or Transflective LCD: Which Do You Need?
An LCD makes no light of its own - it controls light that comes from somewhere else. Where that light comes from is decided by the rear polariser and ...
