INPUT DEVICE AND DISPLAY DEVICE

摘要

An input device that can prevent a reduction in the accuracy of detection of a contact position, even when a display device operates in a PSR mode, is provided. The input device is provided in a display device configured to operate in either a first mode or a second mode, and to generate mode signal giving notice of the current operation mode and is configured to detect a contact position of a user. The input device includes a plurality of driving electrodes and touch controller. Touch controller is configured to determine the operation mode of display device based on mode signal, to generate touch driving signal based on a result of the determination, and to apply the generated touch driving signals to the driving electrodes.

1. A display device configured to operate in any of a plurality of operation modes including a first mode in which the display device operates at a first frame frequency and a second mode in which the display device operates at a second frame frequency lower than the first frame frequency, and to generate a mode signal giving notice of the operation mode, the display device comprising:
a plurality of scanning signal lines; and an input device configured to detect a contact position of a user, wherein the input device includes
a plurality of driving electrodes;a plurality of detection electrodes arranged to intersect the driving electrodes; anda touch controller connected to the detection electrodes, the touch controller being configured to detect a detection signal from the detection electrodes so as to detect the contact position, configured to determine the operation mode of the display device based on the mode signal, configured to generate touch driving signals based on a result of the determination, and configured to apply the generated touch driving signals to the driving electrodes.
