Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional rectangular display devices are combined, then large-size screens can be formed, but the ability to embody a polyhedron and display images continuously in three dimensions is limited
Solution Approach 1:
The display panel is divided into multiple triangular sub-panels arranged in a matrix pattern, where each triangular panel can be independently controlled by separate gate lines. This segmentation allows the display to be assembled into polyhedral shapes while maintaining continuous image display across multiple faces through precise control of each segment.
2Shape
If pixels are arranged in a matrix on a triangular-shaped board, then polyhedron formation becomes possible, but the complexity of controlling gate lines increases due to the stepped arrangement
Solution Approach 1:
The gate-driving unit is divided into multiple gate-in-panels corresponding to different steps in the triangular matrix arrangement. Each gate-in-panel controls a specific row of pixels, allowing independent control of each stepped region. This segmentation simplifies the control complexity by breaking down the overall gate control into manageable independent units.
Solution Approach 2:
The patent introduces a stepped arrangement in the vertical dimension, where pixel rows are offset relative to each other to form a triangular pattern. This dimensional transformation from a flat rectangular grid to a stepped three-dimensional arrangement enables triangular panel shaping while maintaining systematic control through vertically stacked gate-in-panels.
3Shape
If the number of pixels connected to each gate line is controlled to form steps, then triangular shape is achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The triangular shape is formed by segmenting the display into discrete stepped rows, where each row contains a specific number of pixels connected to corresponding gate lines. This segmentation approach transforms the complex continuous triangular geometry into discrete manageable units, reducing manufacturing precision requirements by allowing integer-based pixel counting rather than continuous positioning.
Solution Approach 2:
The patent uses a stepped arrangement where pixel rows are intentionally offset to create the triangular shape, accepting that not all pixels are perfectly aligned in a continuous pattern. This partial alignment approach simplifies manufacturing by using discrete step positions rather than requiring precise continuous positioning, while still achieving the desired triangular form factor.

AI summary
A display device can include a display panel including data lines and gate lines on a triangular-shaped board, and a plurality of pixels in a matrix arrangement, in which pixel rows are arranged with a step for each at least one gate line among the gate lines based on a number of the plurality of pixels connected to each of the gate lines; a data-driving unit on a first side of the triangular-shaped board, and configured to supply data voltages to the data lines to drive the data lines; and a gate-driving unit including a plurality of gate-in-panels (GIPs) on a second side of the triangular-shaped board, in which the plurality of gate-in-panels are arranged to correspond to the step for each of the at least one gate line and sequentially supply a gate signal to the plurality of gate lines to sequentially drive the gate lines.
