Title: Control device and control method
Inventor: NAKAGAWA NAOKI
IPC: G09G5/00
Filed: 2022-02-28
Abstract: To provide a control device and a control method which can specify a failure portion of a component related to image display.SOLUTION: A machine tool 1 includes an operation substrate 26. An FPGA 27 of the operation substrate 26 controls the operation of a display part 20. The display part 20 is the so-called normally white LCD which has a backlight and displays a white light emission screen in such a state that only the backlight is turned on. The FPGA 27 outputs a BL signal that turns on the backlight to the display part 20 and outputs an image signal A to the display part 20. The image signal A is image data of a test pattern D1. When the display part 20 is pitch-dark, it can be determined that the backlight of the display part 20 is out of order. When the test pattern D1 is not displayed on the display part 20 and a pure white light emission screen is displayed after the image signal A is output to the display part 20, it can be determined that the display part 20 is normal and the FPGA 27 is out of order.SELECTED DRAWING: Figure 3
