Solution Overview

Problem

Conventional display apparatuses face challenges in increasing resolution due to the complexity and cost associated with increasing the number of sub-pixels, particularly with the RG/BG sub-pixel arrangement.

Innovation Solution

A display substrate and driving method that organizes pixel groups into first and second sub-pixel groups, where sub-pixels share output values across columns, reducing the overall number of sub-pixels while maintaining high resolution through specific output value calculations.

1Measurement precision

If the number of sub-pixels is increased to achieve higher resolution, then the resolution of the display apparatus is improved, but the fabrication difficulty and cost increase

Engineering Contradiction:
ImproveresolutionVSAvoidfabrication difficulty
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple sub-pixels by implementing a sharing mechanism where one sub-pixel serves multiple pixel positions. Specifically, sub-pixels are arranged in groups where a single sub-pixel's output is shared across multiple pixel columns, reducing the total number of sub-pixels required while maintaining the display resolution through computational imaging techniques.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses computational copying where the optical information from fewer physical sub-pixels is replicated and distributed across multiple pixel positions through signal processing. The shared sub-pixel output is distributed to multiple pixel columns, creating virtual copies of the optical signal to achieve high resolution without proportionally increasing physical sub-pixel count.

Solution Approach 1:

The patent segments the pixel array into distinct groups with specific arrangements. The pixel array is divided into multiple pixel groups, each containing pixel columns with specific sub-pixel configurations. This segmentation allows for standardized fabrication units that can be repeated across the display, simplifying the manufacturing process while achieving the reduced sub-pixel count through the specific RG/BG arrangement within each segment.

AI summary

A display substrate and a driving method thereof as well as a display apparatus. The display substrate comprises pixel groups which are arranged repeatedly, each pixel group comprising a first sub-pixel group and a second sub-pixel group, each comprising four pixel columns. The present invention reduces the number of sub-pixels in the whole display apparatus. Therefore, on a premise of ensuring that the display apparatus achieves a relatively high resolution, the fabrication difficulty of the display apparatus is reduced, and the cost is lowered.
