研究目的
To evaluate the performance of ?exible displays under mechanical strain and propose correction methods to mitigate the impact of strain on display quality.
研究成果
The study demonstrates that mechanical strain can signi?cantly affect the quality of images on OTFT-based ?exible displays. Two compensation methods, Vdata compensation and trow compensation, are proposed to mitigate the impact of strain. Vdata compensation adjusts the data value sent to each pixel, while trow compensation alters the time allowed for charging/discharging each pixel. The choice between these methods depends on the application requirements.
研究不足
The study focuses on two fundamental deformation modes (bending and twisting) and may not cover all possible deformation scenarios. The proposed correction methods may require additional hardware and could increase system complexity.
1：Experimental Design and Method Selection:
The study involves modeling the effects of extrinsic strain on OTFTs due to bending and twisting, translating strain to device mobility variations, and deriving analytical models for error analysis in ?exible displays.
2：Sample Selection and Data Sources:
The study uses a ?exible display with dimensions of 50mm × 50mm ×
3：5μm and 512 × 512 pixels. List of Experimental Equipment and Materials:
The study utilizes ABAQUS for FEA simulations, HSPICE for circuit simulations, and a pentacene-semiconductor-based Wheatstone bridge strain sensor.
4：Experimental Procedures and Operational Workflow:
The study conducts FEA simulations for bend and twist+press deformations, analyzes mobility variation due to strain, evaluates display performance, and proposes two error correction methods.
5：Data Analysis Methods:
The study uses the SSIM metric to compare rendered images with the ideal and evaluates the effectiveness of the proposed correction methods.
