Solution Overview

Problem

In the assembly of liquid crystal displays, differences in the active area of display panels from various manufacturers lead to compatibility issues with mechanism frames, resulting in incomplete pictures due to occlusion, as the frame may cover parts of the display area.

Innovation Solution

A picture compression method and apparatus that calculates the number of occluded sub-pixels, deletes redundant pixel data, and integrates virtual or black data to maintain the aspect ratio, ensuring the un-occluded sub-pixels display a complete image by matching the aspect ratio of the original display area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the mechanism frame is used to press-assemble display panels from different manufacturers, then the assembly process can be standardized, but the edge of the active area will be occluded resulting in incomplete picture display

Engineering Contradiction:
Improveassembly process standardizationVSAvoidpicture display completeness
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent performs preliminary calculation of occluded sub-pixels based on the mechanism frame dimensions and display panel parameters before picture display. By pre-determining which sub-pixels will be occluded and adjusting the picture data accordingly in advance, the system ensures complete picture display while maintaining standardized assembly processes.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If pixel data is deleted to match occluded sub-pixels, then the picture can be displayed completely, but the data processing complexity increases

Engineering Contradiction:
Improvepicture display completenessVSAvoiddata processing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the picture data processing into distinct steps: first calculating the number of occluded sub-pixels, then deleting the corresponding number of pixel data points, and finally integrating the remaining data. This segmentation simplifies the overall processing complexity by breaking down the complex task into manageable, sequential operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter of picture data by adjusting its quantity to match the number of un-occluded sub-pixels. By modifying the data parameter (number of pixel points) to correspond to the physical display capacity, the system achieves complete picture display without excessive processing complexity.

Inventive Principle:
Principle #35Parameter changes

3Shape

If the number of pixel data is reduced to match occluded sub-pixels, then the aspect ratio is maintained, but the processing time increases

Engineering Contradiction:
Improveaspect ratio maintenanceVSAvoidprocessing time
Core Design Contradiction:
ShapeVSLoss of time

Solution Approach 1:

The patent performs preliminary calculation of the number of occluded sub-pixels using simple geometric formulas based on mechanism frame dimensions and display panel parameters. By pre-calculating this value before picture processing, the system minimizes processing time while ensuring correct aspect ratio maintenance through subsequent straightforward data deletion and integration steps.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present disclosure provides a picture compression method for the display panel, the method includes: obtaining the number of occluded sub-pixels in the display area; deleting the pixel data having the same number of the occluded sub-pixels; integrated processing the undeleted pixel data, so that the undeleted pixel data are one-to-one correspondence with the un-occluded sub-pixels; providing the integrated processed undeleted pixel data to the un-occluded sub-pixels, so that the aspect ratio of the picture displayed by the un-occluded sub-pixels is as same as the aspect ratio of the picture displayed by the all of the sub-pixels. The present disclosure further provides a picture compression apparatus of the display panel. The disclosure realizes the purpose of the display screen compression, so as to solve the problem that the screen displayed by the display area is not complete due to the covering of the display area by the mechanism frame.
