Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RGB three-pixel liquid crystal display panels face challenges in high power consumption and image distortion when directly applying data signals to four-pixel display units, necessitating a conversion algorithm evaluation before hardware chip design to ensure design quality.
Innovation Solution
An image displaying method and system that converts RGB three-pixel data signals into four-pixel data signals by demarcating four-pixel display units on a liquid crystal display panel, using a data signal processing unit to simulate four-pixel data signals based on luminance and chrominance of RGB signals, and calculating a gray scale for a fourth pixel data signal to display images effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RGB three-pixel data signals are directly applied to four-pixel display units, then the display process is simple, but image distortion occurs
Solution Approach 1:
The patent applies preliminary action by performing data signal conversion before display. A conversion algorithm transforms RGB three-pixel data signals into four-pixel data signals (RGBW or RGBY) in advance, ensuring proper signal formatting is established before the actual display process, thereby preventing image distortion while maintaining operational simplicity
2Device complexity
If conventional RGB three primary color mixing display manner is used, then the display structure is simple, but transmittance and mixing efficiency are low resulting in high power consumption
Solution Approach 1:
The patent applies parameter changes by modifying the pixel composition parameters from three (RGB) to four (RGBW or RGBY). This structural parameter change increases transmittance by 50% and improves color mixing efficiency, thereby reducing power consumption while maintaining relatively simple display structure through the addition of only one sub-pixel unit
3Measurement precision
If hardware chip design for data signals conversion is carried out, then conversion accuracy is improved, but design time and cost increase
Solution Approach 1:
The patent applies copying by using software simulation to replicate the function of hardware chip design. A simulation evaluation system copies the conversion algorithm behavior in a virtual environment, allowing conversion accuracy to be tested and verified without requiring actual hardware chip design, thereby significantly reducing design time and cost
