Which risk increases when stressed polymer films used in LCD screens lose structural uniformity?

A)Disrupted pixel light polarization
B)Increased electron tunneling effects
C)Elevated quantum dot degradation
D)Reduced backlight LED efficiency

💡 Explanation

Non-uniform film stress leads to inconsistent birefringence; therefore polarized light passing through will be variably rotated due to stress-induced birefringence, rather than consistently blocked, because correct LCD function requires proper polarization control.
