Working Principle

Material Composition & Structural Characteristics

1. Main Display Housing: Matte black high-strength ABS plastic front and rear shell, surface anti-fingerprint matte coating treatment, anti-slip and wear-resistant
2. Display Panel Protection Layer: 8H hardness chemically tempered clear glass overlay, edge chamfer polishing processing to eliminate sharp edges and corners for safe daily operation
3. Electromagnetic Touch Layer: Multi-layer flexible PCB electromagnetic coil film attached to back of LCD panel, uniform distribution of induction coil array covering full screen area to ensure consistent touch precision at all screen positions
4. Foldable Support Stand: Lightweight aluminum alloy metal stand with plastic anti-slip foot pad at bottom, multi-angle gear locking structure for stable tilt angle fixation during long-time counter operation
5. Passive Stylus Components: High-strength plastic stylus main body, replaceable wear-resistant POM plastic pen tip, built-in miniature induction coil and pressure sensor chip inside stylus cavity, no battery compartment design

Installation Technical Requirements

1. Installation Environment Limit: Only install indoor fixed counter desktop, strictly prohibited outdoor sunlight direct irradiation installation, sunlight ultraviolet radiation will accelerate LCD panel backlight aging and screen yellowing
2. Desktop Placement Requirement: Place PD1611 on flat horizontal solid counter desktop, metal support stand fully unfolded and locked to selected tilt angle; no foreign objects placed between display rear shell and desktop surface to avoid blocking ventilation heat dissipation gaps
3. Host Connection Wiring Standard: Use original matched PD1611 integrated USB cable to connect display USB port and host computer USB 2.0 high-speed port; avoid using extended USB hub with multiple parallel power-consuming equipment to prevent insufficient USB output power causing display black screen or touch function failure
4. Driver Installation Operation Rule: Complete official ViewSonic PD1611 dedicated driver program installation before first equipment power-on use; close all running e-signature software during driver installation process to avoid program occupation interrupting driver file registration
5. Ventilation Heat Dissipation Installation Requirement: Keep minimum 10cm clearance behind display rear shell for natural air convection heat dissipation; do not stack paper documents, file folders or other debris on top of display housing to block heat emission

Typical Application Scenarios

1. Banking business hall counter customer electronic signature equipment for loan contract, account opening form, fund transaction document signing
2. Insurance company service hall insurance policy electronic signature terminal for insurance application form, claim settlement document signing
3. Government administrative service center window electronic document signing equipment for identity certification, administrative approval form signing
4. Retail chain store customer electronic receipt signature terminal for large commodity installment sales contract signing
5. Educational institution campus office electronic document annotation and student examination paper electronic marking pen display equipment

Operation & Maintenance Precautions

1. Screen Surface Cleaning Regulation: Only use soft lint-free microfiber cloth slightly dampened with pure water to wipe screen glass surface dust and fingerprint stains; prohibit using alcohol, acetone, glass cleaner containing chemical solvent to wipe screen surface, chemical solvent will corrode tempered glass surface anti-reflection coating
2. Stylus Use & Storage Precautions: Avoid dropping passive stylus from high altitude to prevent internal induction coil and pressure sensor chip damage; replace worn pen tip regularly when handwriting line jitter or broken line phenomenon occurs; store stylus in built-in display side storage slot when not in use to avoid loss
3. Power-On Operation Limit: Do not repeatedly plug and unplug USB connection cable within short time interval during equipment power-on operation; frequent power cycle will cause LCD panel backlight circuit impact damage and shorten backlight service life
4. Long-Term Idle Storage Operation: When equipment not used continuously for more than 7 days, disconnect USB cable power supply from host computer to avoid long-term standby power consumption accelerating internal electronic component aging; store equipment in dry indoor environment with ambient humidity 40%–60% RH, prohibit storage in humid, dusty storage cabinet
5. Anti-Interference Operation Warning: Do not place high-power electromagnetic equipment (high-power printer, wireless router, mobile phone wireless charging base) within 30cm surrounding PD1611 display; strong external electromagnetic field will interfere with internal EMP touch induction circuit, causing stylus handwriting coordinate drift and touch positioning inaccuracy
6. Screen Pressure Damage Prevention: Do not apply heavy external pressure on LCD screen surface, prohibit placing heavy objects on display front glass surface; excessive pressure will crack tempered glass overlay and damage internal LCD liquid crystal layer, resulting in permanent screen display dead pixel and black screen failure
