Solution Overview

Problem

Current white tracking technologies in display devices occupy large storage space and increase calculation difficulty for driving ICs, leading to poor processing efficiency.

Innovation Solution

The method involves representing gray scale data in a first preset format before white tracking and switching to a second preset format after white tracking adjustment, using a formula like Dwt=a*Dm+d, where Dwt is the gray scale data after tracking, and Dm is the initial data, to reduce storage space and calculation load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If 8-bit or 10-bit storage mode is used for white tracking technology, then the brightness adjustment precision is improved, but the occupied storage space increases and calculation difficulty increases

Engineering Contradiction:
Improvebrightness adjustment precisionVSAvoidoccupied storage space
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent changes the bit depth parameter from 8-bit or 10-bit to 6-bit for storing gray scale data after white tracking adjustment. This parameter change reduces the storage space requirement while maintaining sufficient precision for brightness adjustment, as the white tracking adjustment range is limited and does not require the full dynamic range of 8-bit or 10-bit data.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial action by only adjusting the gray scale data within a limited range after white tracking, rather than maintaining full 8-bit or 10-bit precision throughout the entire data processing chain. The 6-bit representation is sufficient for the adjusted data range, eliminating the need for excessive bit depth.

Inventive Principle:
Principle #16Partial or excessive action

2Measurement precision

If 8-bit or 10-bit storage mode is used for white tracking technology, then the brightness adjustment precision is improved, but the calculation difficulty of driving IC increases

Engineering Contradiction:
Improvebrightness adjustment precisionVSAvoidcalculation difficulty
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the data width parameter from 8-bit or 10-bit to 6-bit, which directly reduces the computational complexity for the driving IC. The reduced bit depth decreases the number of calculation operations required while maintaining adequate precision for the white tracking adjustment range.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the necessary precision level (6-bit) required for white tracking adjustment, removing the excess bit depth (2 bits from 8-bit, 4 bits from 10-bit) that contributes to calculation complexity without providing additional benefit for the specific adjustment range.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If 8-bit or 10-bit storage mode is used for white tracking technology, then the brightness adjustment precision is improved, but the processing efficiency of driving IC deteriorates

Engineering Contradiction:
Improvebrightness adjustment precisionVSAvoidprocessing efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent changes the data representation parameter from 8-bit or 10-bit to 6-bit, which improves processing efficiency by reducing the amount of data that needs to be processed. The smaller data size allows for faster computation and memory access in the driving IC while maintaining sufficient precision for the white tracking function.

Inventive Principle:
Principle #35Parameter changes
