Battery powered.
Outdoor ready.
Built for sunlight.
For engineering managers evaluating display solutions where power and readability both matter.
SuRG42-CP
The Problem
Backlight TFTs weren't designed for battery-powered outdoor use
The backlight must be ON 100% of the time — that's not a setting, it's the physics.
☀
Washed out in sunlight
The brighter the sun, the harder to read. High-bright 600+ nit panels partially help — but they burn even more power.
⚡
Serious power draw
Our 4.3" uEZ GUI 43WQN: 250mA @ 5V = 1.25W — backlight only. High-bright displays make this worse.
The Core Insight
Fight the sun, or harness it?
💡
Backlight TFT
Brighter sun → harder to read → more backlight power → still losing. The sun always wins.

☀
SuRG42-CP
Brighter sun → display gets brighter → easier to read. Ambient light is the backlight.
SuRG uses a custom reflective display — the harsher the conditions, the better it performs. No backlight. No power race.
The Numbers
240× less power than a comparable backlit TFT
4.2mW vs 1.25W. Same display size. Fundamentally different architecture.
240×
Less power vs backlit TFT

Real-World Impact
10,000mAh battery pack. Same battery. Very different story.
This is what 240× less power actually means in the field.
Backlit TFT (1.25W)
~2 days
Constant servicing. Impractical for remote deployment.
SuRG42-CP (4.2mW)
~2 years
Deploy and leave. Meters, sensors, ag equipment, outdoor HMIs.
That's the difference between a product that needs constant field servicing — and one that deploys and runs unattended for years.
