Display Controller Blurring Camera Overlap Areas

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Display devices with integrated camera modules face issues where the camera hole interrupts the image display, leading to loss of pixel information and increased bezel area, as the camera area overlaps with the display area, causing image interruption and reduced pixel information.

Innovation Solution

A controller is designed to generate display area information for pixels in overlapping camera areas, blur images in these areas based on shape information, and control the display to minimize pixel loss, using a display panel with distinct resolution areas and an image processing unit to apply a blurring filter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camera hole is formed in the display area to mount a camera module, then the camera can be integrated into the display device, but the image display is interrupted and pixel information is lost in that area

Engineering Contradiction:

Improvecamera integrationVSAvoidpixel information loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent extracts the camera module from the display area and relocates it to the bezel area, thereby eliminating the interruption of image display in the display area while still maintaining camera functionality in the overall device

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent moves the camera module from a two-dimensional display area location to a different spatial dimension (bezel area), allowing both camera integration and uninterrupted image display to coexist by utilizing different spatial zones

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If a camera hole is formed in the display area, then camera integration is achieved, but the bezel area increases

Engineering Contradiction:

Improvecamera integrationVSAvoidbezel area

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The camera module is extracted from the display area and repositioned to the bezel area, which consolidates the non-display elements in one location and prevents display area interruption while managing bezel area utilization

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the camera module is disposed in the display area, then camera integration is achieved, but image display is interrupted

Engineering Contradiction:

Improvecamera integrationVSAvoidimage display continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The camera module is removed from the display area and relocated to the bezel area, ensuring that the display area remains fully functional for continuous image display without any interruptions or visible holes

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The camera module is relocated to a different spatial dimension (bezel area) that does not interfere with the display area, allowing both camera functionality and continuous image display to coexist without conflict

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
