摘要:
In an electronic device switchable between a normal mode and a demonstration mode regardless of a change in software, the demonstration mode can be brought by simple operation while being prevented upon normal use by a user. A demo data detection unit 24 is configured to detect, as demo data D, an image file stored in a specific folder in an external memory ExM connected to an electronic device 10. An operation mode control unit 28 is configured to cause the electronic device 10 to operate in a demo mode in a case where the demo data D is detected in the external memory ExM. On the other hand, in a case where the external memory ExM is not connected and no demo data D is stored in the external memory ExM, the operation mode control unit 28 causes the electronic device 10 to operate in a normal mode.

The present invention provides a driving method and a driving circuit of a display panel and a display device. The display panel comprises: gate lines and data lines and pixel units, the data lines comprises: first data lines and second data lines, and a first predetermined number of first data line(s) and a second predetermined number of second data line(s) are alternately arranged. The driving method comprises a step of: scanning the gate lines in turn, wherein when scanning one gate line, a data voltage signal is applied to the first data lines or the second data lines. The driving method provided by the present invention can allow the pixel units on the OLED panel to display alternately, and since the area of each pixel unit is relatively small with respect to the area of the whole OLED panel, such alternate display manner has a relatively small effect on the image display quality of the OLED panel. Meanwhile, compared to the driving method in the prior art, the driving method provided by the present invention allows lower power consumption of the OLED panel when display at the same brightness is achieved.

A screen display control method includes a screen change operation, which includes, in response to a screen change request, outputting data of a screen to be changed, to a display unit and predicting a next screen change cycle, and an operation of switching into a power saving mode when there is no screen change request. An electronic device includes an event generation unit configured to generate a screen change event, a display unit configured to receive screen change data and change a displayed screen, and a controller configured to in response to a detected screen change event, output data of a screen to be changed, to the display unit, predict a next screen change cycle, and switch into a power saving mode when there is no screen change request.

A mobile device display comprises a normal operating mode and a power save mode. The display comprises an area for use during power save mode operation of the mobile device. The area is a portion of a full display area or the full display area. The mobile device comprises a memory that comprises an application program. The mobile device displays a first content relating to the application program in the area. The content is displayed for a first determined time period or until the mobile device transitions from the power save mode to the normal operating mode, when the mobile device is in the power save mode and the user controllable application program is running, the first determined time period is provided by the application program.

摘要:
A method comprising, in a standard display mode, causing display of a graphical element at a position on a see through display that comprises a light projection display that overlays a light filtration array such that the light projection display projects the graphical element at the position on the see through display and the light filtration array filters ambient light at the position on the see through display, transitioning from the standard display mode to a low power display mode, causing termination of display of the graphical element on the see through display based on the low power display mode, determining that an event has occurred, generating a notification that signifies the event, and causing actuation of the light filtration array such that a plurality of light filtration cells of the light filtration array are selectively actuated in a pattern that depicts the notification is disclosed.

One disclosed method includes registering a graphics buffer with a kernel running on a first processor, storing the registered graphics buffer in memory initially without drawing the graphics buffer to a display, and passing the registered graphics buffer to a kernel display driver directly to draw the graphics buffer to the display, in response to a trigger. The method may further include informing a second processor of the registered graphics buffer and receiving the trigger by the kernel as a message from the second processor. The first processor may receive the trigger as a wake command from the second processor while the first processor is in sleep mode. A partial resume of the kernel is then performed while preventing activation of user space on the primary processor, and the graphics buffer is drawn on the display without using an operating system graphics pipeline of the user space.

A computer-implemented method for managing display-related resources, the method comprising the steps of: receiving (201) an input sequence of images at a server; the method being characterized in that it further comprises the steps of: analyzing (202) presence of input activity at the server; in case of activity presence at the server, adding (203), to an output data stream, a signal indicative of activity presence (303); adding to the output data stream the input sequence of images (304); transmitting the output data stream to a client device for the purpose of managing display-related resources of the client device based on the signal indicative of activity presence (303).
摘要:
Techniques are described for controlling operation of both a host device and a wearable display device connected to the host device based on a use status of the wearable display device. The techniques include automatically determining a use status of a wearable display device based on feedback from one or more touch sensors within the wearable display device that indicates whether the wearable display device is worn by a user. Based on the determined use status, the wearable display device controls its own operation (e.g., controls operation of display screens of the wearable display device, a communication session with the host device, and display processing of data received from the host device). The wearable display device also sends an indication of the use status to the host device. The host device then controls its own data processing for the wearable display device based on the indicated use status.
