Display Screen Core Characteristics
Technology Integration and Display Principles
- VA Technology: Liquid crystal molecules arranged perpendicularly without voltage, achieving pure black background with maximum contrast ratio of 120:1.
- DFSTN Technology: Dual FSTN film compensation structure enables high-definition black/white display with temperature resistance.
- 7-segment Decimal Structure: Composed of 7 "8"-shaped segments to display numbers 0-9 and symbols.
- Negative High Contrast Mode: Opaque black background when off, transparent bright characters when on, with superior readability in dim light.
Performance Parameter Advantages
- Viewing Angle: 170° horizontal and 110° vertical, far exceeding TN screens.
- Power Consumption: Low power consumption ideal for battery-powered devices.
- Temperature Stability: DFSTN structure maintains display quality under high temperatures.
- Contrast: Clear character/background boundaries with prominent visual effect in dim light.
