Solution Overview

Problem

Traditional electronic devices with front-facing components like cameras and sensors require notches or holes in the display, preventing true all-screen displays.

Innovation Solution

A pixel structure with triangular pixel units containing sub-pixels of different colors and a light-transmitting portion at each vertex, allowing for uniform light transmission and integration of under-screen photosensitive elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If notches or holes are provided on display screens to allow external light to enter photosensitive elements, then light transmission is enabled, but the display screen cannot achieve true all-screen display since regions corresponding to front-facing cameras cannot be used to display pictures

Engineering Contradiction:
Improvelight transmissionVSAvoiddisplay area
Core Design Contradiction:
Illumination intensityVSArea of stationary object

Solution Approach 1:

The pixel structure is divided into multiple pixel units, each containing sub-pixels of different colors (red, green, blue) arranged in specific positions. Each pixel unit includes light-transmitting portions at vertices and non-light-transmitting portions at other areas, enabling segmented light transmission across the display screen without requiring large notches or holes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the pixel structure have different optical properties: vertices of pixel units are designed as light-transmitting portions while other regions are non-light-transmitting. This local differentiation allows light to pass through specific areas for photosensitive element integration while maintaining display functionality in other areas, achieving true all-screen display.

Inventive Principle:
Principle #3Local quality

2Illumination intensity

If light-transmitting portions are added to the pixel structure to enable under-screen photosensitive element integration, then light transmission is improved, but the uniformity and regularity of the pixel arrangement may be compromised

Engineering Contradiction:
Improvelight transmittanceVSAvoidpixel arrangement regularity
Core Design Contradiction:
Illumination intensityVSStability of the object's composition

Solution Approach 1:

Within each pixel unit, the light-transmitting portions are positioned asymmetrically at the vertices, while sub-pixels of different colors are arranged in specific asymmetric positions relative to the center. This controlled asymmetry allows light transmission while maintaining the overall regularity of the pixel grid structure across the display.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The pixel structure extends into multiple dimensions with pixel units arranged in repeating patterns across the display surface. The light-transmitting portions at vertices create a three-dimensional light transmission path that does not disrupt the two-dimensional pixel arrangement regularity, allowing both light transmission and uniform pixel display.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
