Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent liquid crystal displays (LCDs) lack the ability to adjust the transmittance of their transparent sub-pixels in real time according to the display image, which is necessary to effectively highlight important image areas while maintaining transparency for unimportant parts, failing to meet the display requirements for transparent displays.
Innovation Solution
A data processing method for transparent LCDs that computes the color saturation of each display pixel using grayscale values of red, green, and blue sub-pixels and adjusts the transmittance of the transparent sub-pixel based on predefined thresholds, allowing for real-time adjustment of transmittance by using specific equations to determine the grayscale value of the transparent sub-pixel.

Engineering Contradiction Analysis
1Reliability
If the transmittance of transparent sub-pixel is controlled independently based on color saturation, then the display effect is improved, but the device complexity increases
Solution Approach 1:
The patent pre-establishes three transmittance calculation equations corresponding to different color saturation ranges (low, medium, high saturation). The system determines which equation to use based on the calculated color saturation of each pixel, and applies the appropriate equation to compute the transparent sub-pixel grayscale value. This preliminary preparation of multiple equations avoids complex real-time adjustments and simplifies the control process while achieving adaptive transmittance adjustment.
2Measurement precision
If the transmittance of transparent sub-pixel is adjusted according to display image importance, then the image clarity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent changes the transmittance parameter of the transparent sub-pixel based on the color saturation parameter of the display pixel. By establishing a correspondence between color saturation levels and transmittance values through predefined equations, the system achieves adaptive transmittance adjustment without requiring high-precision manufacturing control. The parameter transformation from color saturation to transmittance grayscale value simplifies the control precision requirements while maintaining image clarity.
