Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-primary-color display panels have limited color expression capability and high power consumption, leading to increased data transmission volume, and there is no effective method to acquire four-primary-color, five-primary-color, or six-primary-color input signals from three-primary-color input signals.
Innovation Solution
A display control method and device that calculate N-primary-color input signals for an N-primary-color display panel by acquiring M-primary-color input signals, using conversion matrices based on color coordinates to convert the signals, allowing for the display of additional primary colors such as cyan, yellow, magenta, and others, thereby expanding the color gamut.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional three-primary-color display panels are used, then the device complexity is low, but the color expression capability is limited
Solution Approach 1:
The patent introduces a color space conversion module as an intermediary that converts three-primary-color input signals into four-primary-color, five-primary-color, or six-primary-color driving signals. This intermediary component enables the display panel to achieve enhanced color expression capability without requiring the input source to be changed, thus improving adaptability while managing device complexity through modular design
Solution Approach 2:
The patent changes the parameters of the display system by increasing the number of primary colors from three to four, five, or six. This parameter change fundamentally expands the color gamut and color expression capability. The conversion matrices and color space transformation algorithms enable this parameter change while maintaining compatibility with standard three-primary-color input signals
2Adaptability or versatility
If N-primary-color display panel with N≥4 is used, then the color expression capability is improved, but the data transmission volume increases
Solution Approach 1:
The color space conversion module acts as an intermediary that processes and transforms the data. Instead of directly transmitting increased amounts of data for N-primary-colors, the conversion module efficiently calculates the additional color channel values from the standard three-primary-color input signals, thereby reducing the actual data transmission volume required to achieve enhanced color expression
Solution Approach 2:
The patent performs preliminary color space conversion and signal processing before the data is transmitted to the display panel. By pre-calculating the N-primary-color driving signals from the three-primary-color input signals using conversion matrices, the system prepares the data in advance, reducing the real-time data transmission burden and optimizing the data flow
3Adaptability or versatility
If N-primary-color display panel with N≥4 is used, then the color expression capability is improved, but the power consumption increases
Solution Approach 1:
The patent optimizes the power consumption by carefully managing the activation and driving voltages of the additional color subpixels. Through parameter optimization in the conversion matrices and driving signal generation, the system activates only the necessary color channels for each pixel, avoiding unnecessary power consumption while maintaining the enhanced color expression capability provided by four, five, or six primary colors
