Publication number: 20240078967Abstract: Disclosed is an intelligent display board capable of increasing visibility by responding to external environmental factors in real time. The intelligent display board aims to improve a displayed image by minimizing differences in the characteristics of a display element (LED) according to the influence of external sunlight and artificial lighting and temperature. The white color of the display board is moved to be closed to a reference if deviating the reference so that low-level colors that are ignored by sunlight, etc. are darkened and the variance of recognizable colors is increased to make it easy to distinguish, thereby increasing the visibility of the display board. In addition, luminance varying according to temperature is adjusted to compensate for and adjust an image while automatically being applicable to a surrounding environment even with respect to temperature, thereby increasing the quality of an image displayed on the display board.Type: ApplicationFiled: October 26, 2021Publication date: March 7, 2024Inventors: Jae Hwan LEE, Gyu Sang SHIM, Kwang Min KO
