INCORPORATION BY REFERENCE

This application claims priority to Japanese Patent Application No. 2019-161550 filed on Sep. 4, 2019, the entire contents of which are incorporated by reference herein.

BACKGROUND

The present disclosure relates to a foldable display apparatus provided with a display device and a touch panel, and an image forming apparatus including the display apparatus. Particularly, the disclosure relates to a technique of controlling display according to opening and closing of the display apparatus.

A display apparatus in general includes a display, and a touch panel disposed at a screen of the display. When an instruction is given on an icon or a button displayed on the screen of the display by being touched, a position of the touch is detected by the touch panel, and the icon or the button given the instruction is determined based on the position of the touch. In recent years, there is a display apparatus that the display apparatus itself is configured as foldable by imparting flexibility to both the display and the touch panel.

In a generally used information processing apparatus, a first and a second casing are provided, and the information processing apparatus is configured as foldable by a hinge (connecting portion) connecting the first casing with the second casing. If the angle between the first and the second casing is within a non-display angle range, a selection is made between the first and the second casing, and a display provided on the selected casing is caused to perform displaying.

SUMMARY

A technique improved over the above techniques is proposed herein as an aspect of the present disclosure.

A display apparatus according to an aspect of the present disclosure includes a display device, a touch panel, an openable body, an open-close detection device, and a control device. The display device is foldably flexible. The touch panel is disposed at a screen of the display device and is foldably flexible. The openable body supports the display device and the touch panel, and is openable and foldable along with the display device and the touch panel upon receiving an open-close operation. The open-close detection device detects an open state where the openable body is opened, a close state where the openable body is folded, and an open-close movement state where open-close movement continues until either one of the open state and the close state switches to another state. The control device includes a processor and, through the processor executing a control program, acts as a controller. The controller invalidates a touch operation made on the touch panel while the open-close movement state is being detected by the open-close detection device, and validates the touch operation made on the touch panel when either of the open state and the close state is being detected by the open-close detection device and when in a neutral state, the neutral state being where none of the open-close movement state, the open state, and the close state is being detected by the open-close detection device.

A display apparatus according to another aspect of the present disclosure includes a display device, a touch panel, an openable body, an open-close detection device, and a control device. The display device is foldably flexible. The touch panel is disposed at a screen of the display device and is foldably flexible. The openable body supports the display device and the touch panel, and is openable and foldable along with the display device and the touch panel upon receiving an open-close operation. The open-close detection device detects an open state where the openable body is opened, a close state where the openable body is folded, and an open-close movement state where open-close movement continues until either one of the open state and the close state switches to another state. The control device includes a processor and, through the processor executing a control program, acts as a controller. The controller invalidates a touch operation made on the touch panel while the open-close movement state is being detected by the open-close detection device and when in a neutral state, the neutral state being where none of the open-close movement state, the open state, and the close state is being detected by the open-close detection device, and validates the touch operation made on the touch panel when either of the open state and the close state is being detected by the open-close detection device.

An image forming apparatus according to still another aspect of the present disclosure includes the above-described display apparatus, and an image forming device that forms an image on a recording sheet.
