ELECTRONIC EQUIPMENT, TEMPERATURE CONTROLLER, DISPLAY INSPECTION DEVICE, AND DISPLAY CORRECTION METHOD

摘要

PROBLEM TO BE SOLVED: To perform mixed-color display which is free of color shifts, while suppressing the cost to be low. SOLUTION: Two kinds of LED chips of different light emission colors as a backlight are all turned on, to perform mixed-color display on the liquid crystal display part 2 of a temperature controller 1, and the display is imaged by the color camera 18 of a display inspection device 16 to detect the wavelengths of the mixed-color display; and a correction value for correcting the deviations in wavelength (color shifts) from reference mixed-color display and sent to the temperature controller 1, which stores the received correction values in a storage part and controls the drive duty of the two kinds of LED chips and performs mixed-color display whose wavelength deviations are corrected according to the correction value.
