Data Driving Part Selective Gamma Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in reducing size and manufacturing cost while accommodating different gamma characteristics of red, green, and blue colors, particularly in quantum dot display panels where pixel sizes and gamma characteristics vary, leading to suboptimal image display quality.
Innovation Solution
A display apparatus with a data driving part that includes a look-up table (LUT) system to selectively store and output first, second, and third color gamma data, using I2C communication and decoders for polarity control, allowing for adaptive image display across differently sized pixels with distinct gamma characteristics.

Engineering Contradiction Analysis
1Manufacturing precision
If separate decoders are provided for each color (red, green, blue) to handle different gamma characteristics, then display quality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
A single decoder is designed to handle multiple color channels (red, green, blue) by selectively outputting different gamma data based on color identification signals. The decoder universally processes all color types through one structure, eliminating the need for separate dedicated decoders for each color while maintaining the ability to apply color-specific gamma characteristics.
Solution Approach 2:
The patent combines multiple color-specific gamma data sets into a unified decoder structure. Instead of having separate decoders for red, green, and blue colors, the system merges their functions into one decoder that selectively outputs the appropriate gamma data based on the input color signal, thereby reducing overall device complexity.
2Device complexity
If a unified decoder is used for all colors, then device complexity is reduced, but adaptability to different color gamma characteristics deteriorates
Solution Approach 1:
The decoder is designed with dynamic selectivity, where the output gamma data changes based on the input color signal. The decoder can dynamically switch between different gamma data sets (first gamma data for red, second for green, third for blue) based on color identification, making a single static structure adaptable to multiple color requirements.
Solution Approach 2:
The unified decoder provides different gamma characteristics for different color channels through selective output. Each color type receives the appropriate localized gamma data treatment within the unified structure, allowing the decoder to maintain color-specific quality while using a single overall component.
