The first voltage difference is less than the second voltage difference.

An image forming apparatus 1 includes a visible image forming unit 50 that forms a visible image in the air, a screen image generation unit 102 that generates a screen image, and a controller 100 that causes the visible image forming unit 50 to generate the visible image representing the screen image generated by the screen image generation unit 102. When the visible image contains predetermined private information, the controller 100 causes the screen image generation unit 102 to generate a second screen image representing the private information and inclined by a predetermined angle with respect to a main screen of the screen image, so as to restrict a person other than an operator from viewing the private information, and causes the visible image forming unit 50 to form a visible image of the second screen image generated.

Embodiments herein achieve a method for emulating an application running in a secondary device on a primary device. The method includes receiving, by the primary device, information of an event associated with the application running in the secondary device. Further, the method includes emulating, by the primary device, a graphical representation of the application running in the secondary device based on the information of the event. Furthermore, the method includes displaying, by the primary device, the graphical representation of the application running in the secondary device.

To protect confidential data, a mobile device determines whether the mobile device is at a location susceptible to visual capture of confidential data entered into the phone by external cameras. The mobile device determines whether focus of a display is on a field in which confidential data is entered. If the mobile device determines that it is at a location susceptible to an external imaging device visually capturing confidential data input into the input field, then the mobile device activate a light source on a same side as the screen presenting the display.

Provided are a display module and an electronic device. The display module includes a display screen, the display screen comprising a display surface and a non-display surface opposite to the display surface; a first heat conduction member, the first heat conduction member laminated on the non-display surface, a first through hole defined in the first heat conduction member, the non-display surface comprising an exposed portion exposed in the first through hole; a photosensitive module, the photosensitive module laminated on the exposed portion; and a second heat conduction member contacting each of the photosensitive module and the first heat conduction member; the first heat conduction member comprising a first inner sidewall formed due to formation of the first through hole, and a contact area between the second heat conduction member and the photosensitive module is larger than an area of the photosensitive module directly facing the first inner sidewall.

An anti-spy electric device includes a display device, a signal receiving unit, and a first image zooming unit. The display device is configured to display an image on a first image focal plane. The signal receiving unit is configured to receive an anti-spy start signal from a pair of adjustable focus glasses. The first age zooming unit is configured to transform the image displayed on the first image focal plane being displayed on a second image focal plane depending on the anti-spy start signal from the pair of adjustable focus glasses, and the first image focal place is not overlapping with the second image focal plane.

A Graphical User Interface (GUI) is provided for facilitating modification of text colors in a digital image. In an embodiment, the GUI includes a first user interface adapted to display a selectable first set of text colors to appear in a modified digital image. In another embodiment, the GUI includes a second user interface adapted to display a selectable first set of text colors to appear in a modified digital image. In yet another embodiment, the GUI includes various options to facilitate securing of confidential data in the digital image.

A display device and display method thereof are provided in the field of image displaying technology. The display device includes: a controller, a display driver and a barrier driver. The controller is configured to send an image frame to the display driver and send a first instruction to the barrier driver. The display driver is configured to drive the display panel to display the image frame on a plurality of display areas which are parallel and distributed at intervals. The barrier driver is configured to turn on the electrodes of the first display barriers in the barrier panel according to the first instruction. The first display barriers are configured to block light when energized. Apart from the first display barriers, second display barriers are configured to allow light to pass through. The display device thus provides a visible range within a preset narrow viewing angle.

Techniques for sharing protection for a screen sharing experience are described. In at least some embodiments, a screen sharing experience involves a user sharing portions of their display screen with other users as part of a communication session. According to various embodiments, a user that is sharing their screen with other devices as part of a screen sharing experience can protect a portion of the screen from being shared by designating the portion as sharing protected. Thus, content from the identified portion of the user's screen is encrypted to prevent other devices that are unable to decrypt the content from viewing the content. According to one or more embodiments, a user can be designated as sharing privileged such that the user is permitted access to an encryption key to decrypt and view sharing protected as part of a screen sharing experience.

An embodiment of the present disclosure provides a display system which is related to the field of display technology. The display system enables a display device to be switched between a normal display mode and an anti-peeping display mode. This display system comprises a display device which comprises a display panel for displaying content. The display system further comprises: a display mode switch configured to switch between display modes of the display device, the display modes comprising a normal display mode and an anti-peeping display mode; a signal processor configured to provide signals to the display device, wherein the signal processor provide a normal signal to the display device when the display device is in the normal display mode, and the signal processor provide the normal signal and an interference signal alternately to the display device when the display device is in the anti-peeping display mode; and a shutter eyeglass configured to be enabled when the display device is in the anti-peeping display mode, wherein the shutter eyeglass is in an open state when the signal processor provides the normal signal, and the shutter eyeglass is in a closed state when the signal processor provides the interference signal.
