Display Panel White Channel Segmentation for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display subunit color filters in LCD panels have poor light transmission capacity, leading to increased backlight intensity and power consumption when higher screen brightness is required.
Innovation Solution
A display panel design with a white channel and primary color channels, where the display area of the white channel is larger than each primary color channel, allowing for improved light transmission and reduced backlight intensity while maintaining color accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light intensity of the backlight is increased to achieve higher screen brightness, then the screen brightness is improved, but the power consumption is increased
Solution Approach 1:
The pixel is divided into multiple display subunits (first display subunit with color filter, second display subunit without color filter). This segmentation allows different parts of the pixel to have different light transmission characteristics, enabling the system to achieve higher brightness with lower power consumption by utilizing the high light transmission capability of the second display subunit.
Solution Approach 2:
Different display subunits within the same pixel have different local qualities: the first display subunit has a color filter for color accuracy, while the second display subunit lacks a color filter for high light transmission. This local differentiation allows the overall system to achieve both color accuracy and high brightness with lower power consumption.
2Illumination intensity
If the display area of the white channel is increased to improve light transmission, then the light transmission capacity is improved, but the pixel color accuracy may be affected
Solution Approach 1:
The pixel is segmented into multiple display subunits with different functions: the first display subunit contains a color filter for color accuracy, while the second display subunit lacks a color filter for high light transmission. This segmentation allows the system to achieve both high light transmission and color accuracy by combining the contributions of different subunits.
Solution Approach 2:
Different display subunits have different local qualities regarding color filtering. The first display subunit has color filtering properties for accurate color reproduction, while the second display subunit has no color filtering for maximum light transmission. This local quality differentiation enables the system to balance light transmission and color accuracy.
