Display Apparatus Sub-Color Data Compression for Bandwidth Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses face challenges in reducing data bandwidth required for high-resolution displays and improving data recovery after compression, particularly in the context of organic display technology.
Innovation Solution
The implementation of an encoder that separates image data into sub-color data, generates a low frequency component of minor sub-color data, and transmits this as secondary image data, while a decoder uses the low frequency component and high frequency component of major sub-color data to recover minor sub-color data, reducing data bandwidth and enhancing data recovery through discrete wavelet transform.

1Quantity of substance
If image data is compressed to reduce data bandwidth, then data bandwidth is reduced, but data recovery quality deteriorates
Solution Approach 1:
The patent segments image data into multiple sub-color data components (e.g., R, G, B channels) and further divides each into frequency components using wavelet transform. This segmentation allows selective compression of less important components while preserving critical data, thereby reducing overall bandwidth while maintaining recovery quality.
Solution Approach 2:
The patent applies different compression strategies to different parts of the image data based on their importance. Critical sub-color data and high-frequency components are preserved with higher quality, while less critical components undergo greater compression. This local quality approach ensures that data recovery maintains essential visual information while reducing bandwidth.
2Measurement precision
If high-resolution display is implemented, then display quality is improved, but data bandwidth requirement increases
Solution Approach 1:
The patent extracts and separates the essential visual information from the full image data through wavelet transform and sub-color decomposition. By identifying and transmitting only the most critical frequency components and sub-color data needed for high-resolution display, it achieves high display quality while minimizing the bandwidth required to transmit the necessary information.
Solution Approach 2:
The patent transforms image data from the spatial domain to the frequency domain using wavelet transform. This dimensional change allows the system to represent high-resolution image information more efficiently, separating essential visual features from redundant data, thereby reducing bandwidth requirements while maintaining display resolution quality.

AI summary
A display apparatus includes an encoder which compresses first image data to generate second image data, a decoder which recovers the first image data to generate third image data, and a display panel which displays an image, in which the encoder separates the first image data into a plurality of sub-color data, and generates a low frequency component of minor sub-color data among the plurality of sub-color data and the remaining sub-color data as the second image data, and the decoder generates recovery minor sub-color data corresponding to the minor sub-color data by using the low frequency component of the minor sub-color data and the high frequency component of one of the remaining sub-color data in the second image data, and generates the recovery minor sub-color data and the remaining sub-color data as the third image data.
