1. Product and application context
Begin with what the product does, who reads the display and where it operates. The same panel can behave very differently behind a cover lens, outdoors, near heat or inside a battery-powered device.
- End application and target market
- Viewing distance and typical lighting
- Indoor, outdoor, vehicle or handheld use
- New design, replacement or second-source program
2. Mechanical and visible-area information
A 2D outline drawing is the fastest reference. If no drawing exists, provide the target outer size, active area, thickness limit, mounting method and photos or a physical sample.
- Outer dimensions and active area
- Display orientation and viewing direction
- FPC exit, bend area and connector position
- Cover lens, bezel and available assembly space
3. Electrical, optical and environmental targets
Share the controller interface and the conditions that affect readability. Brightness, contrast and power should be chosen together rather than as separate headline values.
- Resolution or segment artwork
- Interface, timing, voltage, duty and bias
- Brightness, contrast, viewing angle and backlight color
- Operating and storage temperature, humidity and sunlight exposure
4. Sample, volume and lifecycle plan
The commercial plan guides tooling, sample quantity, material choices and change-control expectations. Even a range is better than leaving demand and lifetime unknown.
- Prototype and validation quantity
- Estimated annual demand
- Target sample and mass-production dates
- Expected years of production and service support
