Microcontroller Pixel Layout for Narrow-Bezel Display Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving superior display quality with higher color accuracy, better contrast, and more engaging visual effects, while also requiring narrower bezels to enhance the screen ratio.
Innovation Solution
The display device incorporates a driver substrate with a display region and a peripheral region, featuring a first light-emitting unit that includes a microcontroller, pixels, and supplementary pixels. The microcontroller is strategically placed between the pixels and supplementary pixels, with the supplementary pixels being at least partially aligned with the pixels, which simplifies the circuit layout and reduces adverse effects on display quality, thereby preventing jagged edges and allowing for a narrower bezel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the circuit layout is simplified by using a microcontroller to control pixels, then device complexity is reduced, but manufacturing precision requirements increase to prevent jagged edges
Solution Approach 1:
The pixel array is divided into two separate rows: first pixels and first supplementary pixels. This segmentation allows independent control and positioning of each row, enabling the microcontroller to manage them separately while maintaining precise alignment. The segmentation resolves the contradiction by allowing simplified circuit control while achieving the required manufacturing precision through structured division of the pixel array.
Solution Approach 2:
The first supplementary pixels are arranged in a second row that is spatially separated from but aligned with the first pixels in the first direction. This dimensional arrangement allows the circuit to control pixels row-by-row rather than requiring complex simultaneous control of all pixels, simplifying the circuit layout while maintaining precise alignment through the structured two-row configuration.
2Area of stationary object
If the bezel width is reduced to increase screen ratio, then area of display region is increased, but circuit layout becomes more constrained
Solution Approach 1:
The first pixels and first supplementary pixels are merged under the control of a single microcontroller, consolidating what could have been two separate control systems into one. This merging simplifies the circuit layout by reducing the number of control components while still enabling precise control of the expanded display region, thus resolving the contradiction between increased display area and circuit complexity.
Solution Approach 2:
By arranging pixels in two rows and controlling them sequentially through the microcontroller, the patent effectively utilizes the spatial dimension to organize the circuit layout. This dimensional approach allows the circuit to manage a larger display area without proportionally increasing complexity, as the control structure scales efficiently with the two-row pixel configuration.
