Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in achieving high definition imaging without micronizing display cells, leading to reduced luminance due to decreased light intensity or light emitting areas, which can be mitigated by increasing power consumption through backlight intensity or OLED power.
Innovation Solution
A display device with a drive circuit that decomposes original images into sub-sampling images and overlaps adjacent display cell groups to achieve high definition imaging without micronizing display cells, using a matrix arrangement of display cells with different light emitting colors and shifting their positions to optimize light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display cells are micronized to enhance image definition, then image definition is improved, but luminance is reduced due to decreased light emitting area
Solution Approach 1:
The patent divides the display panel into multiple independently controllable display cell groups, where each group can be selectively driven. This segmentation allows the system to activate only the necessary display cells for displaying an image, rather than requiring all cells to be continuously active, thereby maintaining high luminance while achieving fine image definition through selective activation of smaller display cell groups.
Solution Approach 2:
The patent employs time-sequential driving where different display cell groups are activated in different time periods to display different sub-sampling images. By periodically switching between different display cell groups and using temporal multiplexing, the system achieves high definition imaging while maintaining adequate luminance through cumulative light output over time.
2Illumination intensity
If backlight intensity or OLED power is increased to compensate for reduced luminance, then luminance is improved, but power consumption increases
Solution Approach 1:
The patent uses periodic activation of different display cell groups in time-sequential manner. By dividing the display into multiple groups that are activated alternately rather than simultaneously, the system reduces the instantaneous power requirement while maintaining adequate average luminance through temporal multiplexing, thereby lowering overall power consumption.
Solution Approach 2:
The display panel is segmented into multiple independently controllable display cell groups. This allows the system to activate only the necessary portions of the display at any given time, reducing the total power consumption compared to driving all display cells continuously at full intensity, while still achieving the required luminance through selective activation.
3Measurement precision
If display cells are micronized, then image definition is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the display panel into multiple display cell groups that can be independently driven. This segmentation approach allows for modular manufacturing where each group can be fabricated and tested separately, potentially simplifying the manufacturing process compared to creating entirely new micronized pixel structures, while still achieving high image definition through the segmented architecture.

AI summary
Disclosed is a display device capable of achieving a high definition imaging without depending on micronization of display cells. The display device includes: a display panel in which display cells capable of being independently driven are two-dimensionally arranged; and a drive circuit that decomposes an original image that includes plural pixels into plural sub-sampling images that include the pixels which are respectively intermittent in a row direction and a column direction, and sequentially displays the plural sub-sampling images on the display panel. The drive circuit drives a display cell group including plural display cells that are two-dimensionally arranged to be adjacent to each other, corresponding to the respective pixels. The display cell groups respectively corresponding to two arbitrary sub-sampling images are overlapped and are disposed to be mutually shifted.
