What a reflective LCD does differently
A Reflective LCD (RLCD) has no backlight. It modulates the light already falling on it and reflects it back to the viewer, so the brighter the environment, the brighter the image. A conventional transmissive LCD does the opposite: its backlight is fixed, and surface glare in daylight closes the gap between its black and white states until the image disappears.
A Transflective LCD (TLCD) combines both paths — reflective in daylight, backlit at night — for equipment that has to run around the clock.

How reflective LCD works
A walkthrough of the optical stack, the power budget and the conditions each technology is built for.
- How ambient light is modulated and reflected back to the viewer.
- Where the power goes once the backlight is removed.
- Which applications fit RLCD, and which need TLCD.
Four reasons engineers specify RLCD
Sunlight readable
Contrast improves as ambient light increases. There is no backlight to out-shine and no washout at 100,000 lux.
Ultra-low power
Removing the backlight removes the largest load in the system. A static frame holds at milliwatts.
Industrial range
Specified for continuous operation from −30 °C to +85 °C, with no backlight lifetime to derate.
Integration support
Our engineers size the panel, specify the interface and review your optical stack before you commit to tooling.

Not in the range yet
Reflective and transflective panels are also built to a diagonal, aperture and interface you specify. Send the enclosure drawing and the power budget and we will tell you what is possible.
Choosing between four display technologies
Compare readability, power, motion and temperature against the conditions your product actually operates in.
| Criterion | Reflective LCD | Transflective LCD | Transmissive LCD | E-paper |
|---|---|---|---|---|
| Direct sunlight | Improves with light | Reflective path holds | Washes out | Readable |
| Backlight required | No | Night operation only | Always on | No |
| Typical panel power | Milliwatts | Milliwatts to watts | Watts | Milliwatts, static |
| Full-motion video | Yes | Yes | Yes | No |
| Colour | Full colour | Full colour | Full colour | Limited |
| Operating range | −30 °C to +85 °C | −30 °C to +85 °C | Derated by backlight | Narrower |
Typical behaviour for the technology class, not a specific part. Request the datasheet for the module you are evaluating.
What we will measure for your design
We do not publish a headline figure without the conditions behind it, because reflectance and power both depend on the stack and the duty cycle you end up with. These are the four we characterise per module.
Reflectance and contrast
Measured at the ambient levels your product actually sees, with the test geometry stated. Contrast on a reflective panel rises with ambient light rather than falling.
Power against duty cycle
With no backlight in the stack, draw is dominated by how often the frame changes — so we measure it against your refresh pattern, not a datasheet maximum.
Temperature range
Characterised across the full specified range rather than at room temperature, because an unconditioned enclosure spends most of its life outside it.
Service life
The backlight is usually the first thing to fail in the field. Removing it removes its lifetime curve, so we characterise what is left instead of quoting the LED figure.

View ApplicationWe publish a result once the customer has approved the numbers in it
Reflective panels are usually specified into products under NDA, so the first case studies are with their engineering teams rather than on this page. We would rather show you nothing than a composite.
In the meantime we can put you in touch with a reference in your own sector, or send the measured figures for the module you are evaluating with the conditions behind each one.
What a reference covers
References are arranged directly with the customer. Some are available under NDA only.
01
The requirement they started from, and the panel they were replacing.
02
What changed on the board and in the enclosure to take the module.
03
The measured result, with the conditions it was measured under.
Engineering support
How a specification gets settled
01
Send the requirement
Enclosure drawing, viewing distance, power budget and operating temperature. Nothing else is needed to start.
02
Get a specified module
We return a panel, interface and driver recommendation with the reflectance and power figures behind it.
03
Review before tooling
Our engineers review the optical stack, the cover lens and the bonding method against your build.

Datasheets
Each module is characterised before its datasheet publishes, so we issue the current specification directly rather than list a stale one here.
