1. Outside Dimension (OD): The total physical footprint of the display module, including the metal frame.
2. Bezel Opening: The visible window area within the metal frame that exposes the display. 3. Active Area (AA): The actual pixel-driven display region; typically aligns with the "Key Area" of a PCAP touch panel for optimal integration.
Note for Engineers: For optical bonding applications, please refer to the specific Polarizer (POL) boundary in our full mechanical drawing. To ensure optimal performance, avoid contact with the Polarizer area during assembly.
Reading PCAP Panel Drawings
1. COVER OD (Outside Dimension): The total physical boundary of the cover glass, defining the exact outer dimensions required for mechanical housing and bezel integration. 2. SENSOR AA (Active Area): The functional sensing region of the touch panel where coordinate detection occurs; crucial for touch performance and sensitivity. 3. COVER VA (Viewing Area): The transparent region of the cover glass, typically aligned with the display’s visible window; defines the area where the user can see the display content through the touch panel.
Integration & Assembly Guidelines
01
Structural Alignment
The COVER VA must be precisely aligned with the display’s visible window to ensure visual clarity and avoid any potential obstruction.
02
Optimal Visibility
For best display performance, the COVER VA should be positioned between the display's Active Area and the Bezel Opening.
03
Touch Accuracy
To ensure superior touch responsiveness, the Key Area of the PCAP should be strictly related to and aligned with the display’s Active Area.
04
Insulation Standards
If the front mechanical frame is made of conductive material, you must include a proper insulation layer between the frame and the PCAP surface.
05
Reasonable Price
When designing your front mechanical frame, ensure it fully covers the silver routing traces on the PCAP to prevent signal interference or electrical shorts.
06
FPC & ESD Safety
Use non-conductive material (thickness ≥ 1mm) to isolate the FPC from mechanical stress; strictly follow anti-static (ESD) protocols throughout the assembly process.
