I. Classified by Working Principle (Core Classification)1.Surface Capacitive Screen
- Single-layer glass, four-sided electrodes
- Supports only single touch, no multi-touch function
- Advantages: low cost, scratch resistance and dustproof
- Disadvantages: no multi-touch, invalid with gloves, low precision
- Application: Old access control systems, simple query terminals
2.Projected Capacitive Screen (Mainstream Type)
- Self-capacitive type: simple structure, low cost, prone to false touches, widely used for small keys and home appliance touch buttons
- Mutual-capacitive type: supports multi-touch, high precision and smooth gestures. Widely applied in mobile phones, tablets, industrial control and large screens. Nearly all mainstream capacitive screens belong to this type.
II. Classified by Layer Structure (Common Lamination Types in Industry) 1.G+G Structure (Glass to Glass)
- Upper protective glass + lower sensing glass
- High hardness, scratch resistance, long service life and excellent stability
- Slightly thick, relatively high cost
- Preferred for industrial control, vehicle and industrial equipment
2.G+F Structure (Glass + Film)
- Upper glass + lower flexible film sensing layer
- Lightweight and low cost
- Softer texture, inferior scratch resistance and service life compared with G+G
- Commonly used in consumer home appliances, mid-range tablets and smart home devices
3.G+F+F Structure
- Double-layer film with denser touch wiring, higher precision and multi-touch support. Widely used in mid-to-high-end handheld devices
4. Full Lamination / In‑Cell / On‑Cell
- In-Cell: Touch layer embedded inside LCD panel, thinnest with superior display effect
- On-Cell: Touch layer attached on LCD surface
- Mainstream for smartphones and high-end tablets, high cost and expensive maintenance
III. Classified by Touch Form & Appearance Shape
- Regular rectangular capacitive screen: Most common type with standard aspect ratio
- Circular capacitive screen: applied on watches, knobs and circular dashboards
- Irregular screen: punch-hole, rounded corner, chamfered corner, long special shape
- Curved capacitive screen: 2.5D arc, 3D curved and flexible screen
- Narrow long screen: for vehicle strip displays and home appliance long touch panels
IV. Classified by usage environment and functional features
- Standard capacitive screen: indoor normal temperature, finger touch operation
- Waterproof capacitive screen: suitable for outdoor, wash basin and industrial control waterproof devices, splash and rain resistant
- Glove-touch capacitive screen: supports thin work gloves and stylus operation
- Industrial anti-interference capacitive screen: strong EMI resistance, applicable to inverters, industrial cabinets and vehicle high electromagnetic environments
- Ultra-narrow bezel capacitive screen: borderless & slim design, ideal for aesthetic all-in-one devices
V. Classified by size and application scenarios
- Micro small size: 1.3-4 inches, used for watches, earphone charging cases and small home appliance buttons
- Small & medium size: 5-10.1 inches, for handheld terminals, industrial tablets and car navigation
- Medium & large size: 12-32 inches, all-in-one devices, self-service terminals, advertising displays
- Extra-large size: 43-98 inches, conference panels, teaching blackboards, exhibition large screens
