Under-screen Camera Display with Segmented Pixel Density

Solution Overview

Problem

Conventional display screens with non-display regions above the active display area lead to an unfavorable user experience, particularly in smartphones with touch control functions, due to the presence of a non-display region that reduces the screen-to-body ratio and light transmittance.

Innovation Solution

A display screen design featuring a first region with a lower physical pixel density for accommodating under-screen photosensitive modules, such as cameras, and a second region with a higher pixel density for main display purposes, allowing for full-screen display and increased light transmittance by arranging sub-pixels in specific patterns to create gaps for light transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a non-display region is provided above the active display region to accommodate photosensitive modules, then the photosensitive modules can function properly, but the screen-to-body ratio and light transmittance are reduced

Engineering Contradiction:

Improvephotosensitive module functionalityVSAvoidscreen-to-body ratio

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The display screen is divided into two distinct regions: a first region with lower pixel density for accommodating photosensitive modules and a second region with higher pixel density for main display purposes. This segmentation allows each region to serve its specific function optimally while eliminating the need for a separate non-display region.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different pixel densities are applied to different regions of the display screen. The first region has a lower physical pixel density to allow light transmission for photosensitive modules, while the second region has a higher physical pixel density for high-quality display. This local differentiation resolves the contradiction by making each region's properties match its functional requirements.

AI summary

A display screen and a display apparatus. The display screen includes a first region and a second region. The first region has a physical pixel density smaller than that of the second region. By providing a first region and a second region and having a greater physical pixel density in the second region than that in the first region, light can transmit through the gap between the pixels in the first region configured to house the under-screen photosensitive module such as a camera and the like, so as to achieve a high light transmittance and therefore to achieve an entire screen or full screen display. A non-display region above the active display region can be omitted and the screen-to-body ratio is increased, user experience is optimized and thus the technical problem of unfavorable user experience due to the presence of the non-display region is addressed.
