具前光補償的彩色電子紙

Abstract

電子紙是一種反射式顯示器，具有類似紙張的特性，由於其低功耗和高可讀性，被廣泛應用於閱讀設備、電子書和各種屏幕。然而，在一般環境光下，彩色電子紙在顏色表現方面存在一定的限制。為了克服這一問題，本研究旨在探討如何利用前光技術提升電子紙在一般照明環境中的顯示性能。本論文提出了一套完整的電子紙前光處理方案，具體步驟如下：進行前光組合的量測，構建完整的前光色域模型；根據輸入影像選擇最佳前光，確保該前光下的電子紙色域範圍能夠包含最大的影像色域範圍；根據所選定的前光，進行影像校正與色域映射最佳化。整個系統已經實現並驗證，結果顯示電子紙顯示品質得到有效提升。這項前光技術的應用使得彩色電子紙在各種環境光條件下都能呈現更為優越的顏色表現。

Electronic paper is a reflective display with characteristics similar to paper. Due to its low power consumption and high readability, it is widely used in reading devices, e-books, and various screens. However, in typical ambient light, color electronic paper has certain limitations in color performance. To overcome this issue, this study aims to explore how front light technology can enhance the display performance of electronic paper in general lighting conditions.This thesis introduces a comprehensive front light processing solution for electronic paper, involving the following specific steps: measuring the front light combination to construct a seamless front light color space model; selecting the optimal front light based on input images to ensure that the electronic paper color gamut under that front light encompasses the maximum image color gamut; conducting image correction and color gamut mapping optimization based on the chosen front light.The entire system has been implemented and validated, demonstrating effective improvement in the electronic paper display quality. The application of this front light technology enables color electronic paper to exhibit superior color performance under various ambient light conditions.
