OLED Display Driver Corner Integration for Frame Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OLED display devices with active driving mode have a larger frame region due to the distribution of gate lines, data input lines, and power supply lines on the periphery, which increases the non-display area and frame size.
Innovation Solution
The OLED display device design includes a source driver chip and a gate driver chip arranged on the same side, with connection lines for scan and data signals led out from the source driver chip, featuring interlaced and symmetrically arranged gate and source driving units, and inclined or parallel connection lines to reduce the circuit wiring area and frame size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gate lines, data input lines, and power supply lines are distributed on the periphery to form a frame region, then the display device can be driven properly, but the frame region becomes larger
Solution Approach 1:
The patent moves the driver chips from the peripheral frame region to the corner region, utilizing the corner space more efficiently. The connection lines are routed through the corner area rather than forming a complete frame around the display region, thus reducing the frame region while maintaining proper driving function.
Solution Approach 2:
The patent integrates both the source driver chip and gate driver chip into the corner region together, rather than distributing them separately along the periphery. This merging of driver functions in a consolidated corner location reduces the overall frame region required while maintaining all necessary driving capabilities.
2Reliability
If driver chips and connection lines are arranged on the periphery, then signal transmission is ensured, but the circuit wiring area increases
Solution Approach 1:
The connection lines are routed through the corner region where the driver chips are located, rather than extending along the entire periphery. This changes the wiring path from a peripheral frame configuration to a corner-concentrated configuration, reducing the circuit wiring area while ensuring signal transmission between the driver chips and display elements.
Data Source
AI summary
In an organic light emitting diode (OLED) display device, a source driver chip is connected with the data lines through a plurality of first connection lines, and a gate driver chip connected with the scan lines through a plurality of second connection lines. The source driver chip and the gate driver chip are arranged on a same side of the OLED display device, and the first connection lines and the second connection lines are led from a side of the source driver chip.
