Optical Filter Layout for Under-Display Camera Light Collection

The patent applies local quality by differentiating the optical filter structures into two types: first optical filter structures in the first display region with higher light transmittance for better light collection, and second optical filter structures in the second display region with lower light transmittance for standard display quality. This localized differentiation resolves the contradiction by allowing the full-screen region to have optimized light transmission properties specifically where the photosensitive element is located.

The patent changes the light transmittance parameter of the optical filter structures based on their location. The first optical filter structures have a light transmittance greater than that of the second optical filter structures, creating a parameter gradient that optimizes light collection in the full-screen region while maintaining display quality in other regions. This parameter differentiation directly addresses the light collection effect deterioration problem.

The patent implements local quality by creating two distinct types of optical filter structures with different light transmittance characteristics. The first optical filter structures are specifically designed for the first display region to enhance light collection, while the second optical filter structures serve the second display region. This localized approach prioritizes light collection efficiency in the critical full-screen region over manufacturing uniformity.

The patent segments the optical filter layer into multiple types of optical filter structures based on their functional requirements. By dividing the display panel into a first display region (with photosensitive element) and a second display region, and assigning different optical filter structures to each region, the patent optimizes light collection efficiency where needed while maintaining overall system functionality.
