Patent number: 10268439Abstract: In a prediction system, terminal devices having monitors connected thereto and a server can communicate with each other through a network. Each terminal device acquires a luminance measured by a corresponding monitor and transmits it to the server. The server predicts the life of the monitors on the basis of information from the respective terminal devices and notifies the predicted life. The server previously stores information about the installation locations of the monitors. The server notifies the predicted life in such a manner that the installation location of each monitor and the predicted life are associated with each other. Each terminal device acquires, from a corresponding monitor, a measured luminance, a brightness setting at the time when the luminance has been measured, and information about the time when the luminance has been measured and transmits them to the server.Type: GrantFiled: November 7, 2014Date of Patent: April 23, 2019Assignee: EIZO CorporationInventors: Yoshikazu Sakai, Takao Mori, Chiori Terashima

Patent number: 10026364Abstract: A life prediction method and device that can predict the life of a display device considering the differences between temperatures at measurements of the luminance of the display device. A monitor measures the luminance of the display screen using an optical sensor and measures the temperature around the display screen using a temperature sensor. A terminal device stores the measured luminances and temperatures in such a manner that the luminance and temperature are associated with each other. On the basis of the measured luminances and temperatures obtained by repeated measurements, the terminal device predicts the trend of changes in the luminance assuming that the temperatures at the measurements have been approximately constant, and predicts the life of the monitor on the basis of the predicted change trend.Type: GrantFiled: January 17, 2014Date of Patent: July 17, 2018Assignee: EIZO CorporationInventor: Yoshikazu Sakai
