Mixed-Pixel Image Processing for Field Sequential Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field sequential display devices require high refresh rates and suffer from bandwidth waste and frame dropping due to inefficient data transmission when displaying high-resolution images, as they need to process and transmit multiple monochrome images to achieve color display.
Innovation Solution
An image processing method that determines color values of original pixels, generates mixed images based on pixel-position mapping, and transmits these images to a field sequential display device, reducing bandwidth requirements by combining multiple color components into a single mixed pixel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple monochrome images are transmitted separately for each color channel, then color display is achieved, but bandwidth is wasted and frame dropping occurs
Solution Approach 1:
The patent merges multiple color channel images (RGB) into a single mixed image by interleving pixel data. Instead of transmitting three separate monochrome images for red, green, and blue channels, the invention combines them into one image where pixels from different color channels are arranged in a specific sequence, thereby utilizing bandwidth efficiently and preventing frame dropping while maintaining color display capability.
2Speed
If refresh rate is increased to achieve smooth color display, then display quality improves, but bandwidth pressure increases
Solution Approach 1:
By combining multiple color channel images into a single mixed image, the patent reduces the total number of image transmissions required. This allows the system to maintain high refresh rates for smooth color display without proportionally increasing bandwidth consumption, as the merged image structure enables more efficient data transmission compared to separate channel transmissions.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces bandwidth pressure and prevents frame dropping by optimizing data transmission, allowing efficient display of high-resolution images with reduced bandwidth usage.
Implementation Method 1
the field sequential display device can control liquid crystals and color films of pixels to control the pixels to sequentially display monochrome images with different colors, and with help of 'visual persistence effect', display effect of a color image is presented

AI summary
An image processing method and apparatus. The method includes: determining color values of original pixels in an original color image, where for each of the original pixels, the original pixel includes N original sub-pixels corresponding to different basic colors of a color model respectively, a color value of the original pixel includes color components of the basic colors corresponding to the N original sub-pixels, and N is a positive integer greater than 1; generating mixed images corresponding to the N basic colors respectively according to the color values of the original pixels, where N original pixels in the original color image corresponding one-by-one to N mixed sub-pixels in the mixed pixel are determined, and color components of the basic color in the color values of the N original pixels are determined as color components corresponding to the N mixed sub-pixels respectively.
