Product Description
A PC/PMMA screen panel is a type of optical film or cover panel used in display technology, typically as a top layer for LCDs, touchscreens, or display modules. It is composed of a multilayer structure combining Polycarbonate (PC) and Polymethyl Methacrylate (PMMA), often through co-extrusion or lamination processes.
Key Features:
Material Composition:
PC (Polycarbonate): Provides high impact resistance, durability, and flexibility, making the panel less prone to cracking or shattering.
PMMA (Acrylic): Offers excellent optical clarity, scratch resistance, and UV stability, ensuring high transparency and surface hardness.
Structure:
The panel usually consists of a PMMA outer layer for hardness and optical performance, bonded to a PC substrate for toughness. Some designs may include multiple layers or coatings for additional functionalities.
Advantages:
Enhanced Durability: Combines the strength of PC with the hardness of PMMA, resisting impacts, scratches, and daily wear.
Optical Performance: High light transmittance, minimal haze, and good anti-glare properties (if treated).
Lightweight: Thinner and lighter than traditional glass panels, beneficial for portable devices.
Cost-Effective: Often more affordable than pure glass or other high-end alternatives while maintaining good performance.
Applications:
Widely used in smartphones, tablets, laptops, automotive displays, industrial control panels, and consumer electronics where a balance of durability, clarity, and cost is required.
Also employed in touchscreens (resistive or capacitive) as a protective cover lens.
Limitations:
May be less scratch-resistant than glass (e.g., Gorilla Glass) unless specially coated.
Can be susceptible to chemical damage or yellowing under prolonged UV exposure if not adequately treated.
In summary, a PC/PMMA screen panel is a hybrid composite material solution that optimizes both mechanical robustness and optical quality, serving as a practical alternative to pure glass or single-polymer panels in many display applications.

Custom thickness 0.2mm-1mm
AtThe typical thickness of a PC/PMMA composite panel for screen applications generally ranges from 0.5 mm to 3.0 mm. However, the most common and industry-standard thicknesses fall within a narrower band.
Standard Thickness Ranges by Application:
Mobile Devices (Smartphones, Tablets):
Range: 0.5 mm to 1.2 mm
Most Common: 0.7 mm to 1.0 mm
Rationale: This range provides an optimal balance between slim design, sufficient stiffness for touch operation, and impact resistance. High-end models might use the thinner end for premium feel, while rugged or budget devices may use thicker panels for extra durability.
Automotive Displays & Industrial HMIs:
Range: 1.2 mm to 2.5 mm
Most Common: 1.5 mm to 2.0 mm
Rationale: These applications demand higher durability, structural integrity for larger unsupported areas, and often require integration with capacitive touch sensors. Thicker panels resist vibration, temperature fluctuations, and potential impacts better.
Consumer Electronics & Appliance Panels (TV Bezels, Control Panels):
Range: 1.0 mm to 3.0 mm
Most Common: 1.5 mm to 2.5 mm
Rationale: Thickness is chosen for mechanical strength, ease of mounting/fastening, and to prevent flexing or bowing over larger surface areas.

Product application
PC/PMMA composite panels are widely used across industries due to their balanced properties of optical clarity, impact resistance, lightweight nature, and cost-effectiveness. Their key applications include:
1. Consumer Electronics
Smartphones and Tablets: Frequently used as protective cover lenses for displays and touchscreens in mid-range and budget devices. They offer a good compromise between the premium feel of glass and necessary durability.
Laptop and Monitor Bezels/Shells: Used for the non-display frame surrounding the screen, providing a glossy, aesthetic finish that is more impact-resistant than brittle alternatives.
Television Front Frames: Applied in some TV models as part of the border or decorative front panel.
2. Automotive Displays
Central Control Panels (Infotainment Systems): Used as the touch-sensitive cover lens for in-car entertainment, navigation, and climate control systems. Their shatter-resistance is a critical safety feature.
Instrument Clusters: Serves as the clear cover over the digital or semi-digital gauge clusters behind the steering wheel.
Rear-Seat Entertainment Screens: Provides a durable viewing surface for passenger screens.
3. Industrial and Commercial Equipment
Human-Machine Interface (HMI) Panels: Ideal for touchscreens on factory automation equipment, medical devices, ATMs, kiosks, and point-of-sale (POS) systems where durability against impacts and chemicals is essential.
Control Panels: Used on appliances, machinery, and vending machines.
Nameplates and Indicator Windows: Used for backlit logos, status indicators, and informational labels due to good light diffusion properties.
4. Home Appliances
Control Panels on Appliances: Commonly found on microwaves, ovens, washing machines, and refrigerators as the interactive touch surface or protective window for displays.
5. Lighting and Diffusers
LED Light Guides and Covers: PMMA's excellent light transmission and PC's toughness make the composite suitable for LED panel lights, light guide plates (LGPs), and decorative lighting covers where even diffusion and durability are needed.

FAQ
In the fields of industrial equipment, intelligent instruments, etc., PC mechanical windows bear the dual responsibility of protecting internal components and ensuring observation clarity. The long-term stability of their transmittance directly affects the effectiveness of equipment use. But can the transmittance of PC mechanical windows be maintained above 90% for a long time? This depends on the synergistic effect of multiple factors such as material selection, process control, and usage maintenance.
PC partitions are known as "transparent steel plates" due to their excellent impact resistance and are widely used in electronic device protection, home partitions, and other scenarios. With the increasing demand for personalization, customized printing has become a common processing method for PC partitions, but many people are concerned that pattern printing will weaken their impact resistance. In fact, this influence is not absolute, but depends on the comprehensive effect of printing technology, material selection, and processing details.
PC door panels are widely used in home storage, laboratory workstations, medical equipment enclosures, and other scenarios due to their impact resistance, excellent transparency, and easy cleaning properties. As the high temperature season approaches or in environments close to heat sources, whether PC door panels will release harmful substances has become a core concern for users. In fact, this issue needs to be comprehensively judged based on the heat resistance characteristics, potential risks, and product quality of PC materials, and cannot be generalized.
When it comes to protective shields made of PC material, many people immediately think of the face shields worn by medical staff. However, with advancements in material technology, these shields—characterized by high transparency and impact resistance—have evolved far beyond their original role of "blocking droplets." From frontline diagnostics to the protection of precision equipment, their new applications are increasingly evident.
