Display Driver Chip Placement for Compact Screen Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses have a significant peripheral area at the upper and lower sides due to the placement of the driver chip, which increases the length of the device and limits the placement of buttons or other operating components near the display screen.
Innovation Solution
The display apparatus is designed with a reduced peripheral area by strategically placing the driver chip and gate driving circuit in specific peripheral areas, using data signal applying lines to connect with the driver chip, and incorporating a light shielding layer to minimize the display area's upper and lower widths, allowing for a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the driver chip is located in the upper or lower portion of the display area, then the display apparatus can be assembled with standard components, but the length of the display apparatus increases
Solution Approach 1:
The driver chip is repositioned from the traditional upper/lower position to the left/right side of the display area, changing the spatial dimension of component placement. This dimensional shift reduces the vertical length requirement while maintaining all necessary electrical connections through appropriately routed data signal lines.
2Length of stationary object
If the driver chip is positioned to minimize display area width, then the device becomes more compact, but the data signal transmission path becomes longer
Solution Approach 1:
The data signal transmission path is segmented into multiple dedicated lines, with specific lines assigned to connect particular data lines to the driver chip based on their spatial relationships. This segmentation allows for optimized routing where each data signal line follows the most efficient path, reducing overall signal transmission distance while maintaining compact display area dimensions.
3Ease of operation
If buttons are to be disposed at the side of the display screen, then the device achieves better ergonomics, but the upper-and-lower lengths of the display screen must be decreased
Solution Approach 1:
The driver chip placement is shifted to the left/right side of the display area, which reduces the vertical height requirement of the display screen. This dimensional reconfiguration creates additional vertical space that can be utilized for ergonomic button placement at the sides of the display, improving ease of operation without compromising display functionality.
Data Source
AI summary
A display apparatus includes a first substrate, a second substrate, and a driver chip. The first substrate includes a plurality of gate lines disposed in the display area and extended in a first direction, a plurality of data lines disposed on a gate insulating layer insulating the gate lines and extended in a second direction substantially perpendicular to the first direction, and a gate driving circuit section disposed in the first peripheral area adjacent to first ends of the gate lines. The second substrate is opposite to the first substrate. A liquid crystal is interposed between the first and second substrates. The driver chip is disposed in the second peripheral area adjacent to second ends of the gate lines opposite to the first ends so that the width of the upper and lower portions of the display area may be decreased.
