Specifications and Recommendations

Antenna and Webcam Cable Placement: Avoid placing cables behind the LCM to prevent issues during tests. If necessary, use grooves or higher sponges for protection.
LCM Attachment: Use stretch remove tapes aligned with the LCM back-bezel. Avoid tape overlap to prevent structural issues.
LCM Pressing: Ensure pressure is applied to the LCM frame, not the panel, to prevent breakage.
Wire Placement: Position wires between protrusions and A-cover to avoid interference and potential damage.
A-cover Strength: Rib height should exceed LCM height to prevent pressure on LCM edges. L Brackets are recommended for additional strength.
Surface Integrity: Ensure no burrs or gaps near logos to prevent stress concentration and potential damage.
Keyboard and Mouse Pad Design: Avoid right angles to prevent LCM fragments during reliability tests.
System Cover Reliability: Ensure no permanent deformation touches the LCM post-reliability tests.
Magnetic Interference: Avoid magnetic objects near LCM PCBA to prevent noise issues.
Sponge Placement: Attach sponges to A-cover's Boss side wall to reduce panel breakage risk.
Connector and FPC Alignment: Stagger positions to prevent FPC cracks during testing.

Signal and Impedance Standards

HPD Signal Recognition: Ensure HPD glitches are above 2.0V for normal operation.
HPD Signal Definition: Source devices should recheck sink status if HPD signal is low for 0.5ms to 1ms.
Main Link Eye Diagram: Must meet VESA TP3 standards, measured through access fixtures.
Impedance Profile: Cable assembly should maintain a 100Ω impedance with specified tolerances.
Pixel Frequency Information: Fix pixel frequency values to prevent abnormalities post-power on.
PWM Signal for LED Drivers: Calculate duty cycle to avoid visible backlight flicker, adhering to specified PWM rise and fall times.
