Abstract: Discussed are an optical compensating system and method. Specifically, there can be provided an optical compensating method, comprising generating initial flat data for a display panel in a flat state displaying a test image, generating initial curve data for the display panel in a curved state displaying the test image, extracting point data for a plurality of points in the initial flat data and the initial curve data, generating deviation data using the point data, generating a curve data map by applying a weight according to a curvature at each point to the deviation data, generating final curve data by applying the curve data map to the initial curve data, and generating compensation data from the final curve data.

Abstract: Embodiments of the disclosure relate to an optical compensating system and method. Specifically, there may be provided an optical compensating method, comprising generating a first photographed image for a first area of a display panel including an overlapping area, generating a second photographed image for a second area of the display panel including the overlapping area, extracting a camera gamma value for the second area, calculating a reference grayscale value in the overlapping area, using the camera gamma value for the second area, generating a corrected luminance value of the overlapping area by applying weights on the basis of the position to the reference grayscale value, generating compensation data from the corrected luminance value, and transmitting the compensation data to a display device.

Abstract: A flexible display device and a method for manufacturing a flexible display device are provided. A flexible display device includes: a support substrate having a first thickness and including a first material, the support substrate further including first and second main faces opposite to each other, a buffer substrate on the first main face of the support substrate, the buffer substrate having a second thickness smaller than the first thickness, and the buffer substrate including a second material more flexible than the first material, a thin-film transistor array on the buffer substrate, such that the buffer substrate is between the thin-film transistor array and the support substrate, and a sealing substrate fixed above the thin-film transistor array, the thin-film transistor array being between the buffer substrate and the sealing substrate.
