A method for displaying an image, an electronic device and a computer readable medium. The method for displaying an image includes: on the basis of the number of color bits of the image to be displayed, determining at least one image color data item associated with the image; determining at least one device color data item corresponding to the at least one image color data item, the length of the device color data item matching the number of color bits of a display device; and replacing the at least one image color data item with the at least one device color data item so as to display the image on the display device. The method for displaying an image can reduce the impact on the consumption of system memory resources due to the use of a high-capacity and high-resolution display.

Provided is a display device including: an inputter/outputter comprising circuitry configured to request a content providing device to provide content at a first resolution and receive a first image at the first resolution from the content providing device, a display configured to display the first image, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory to: change a resolution requested to the content providing device from the first resolution to a second resolution, control the display to receive a second image from the content providing device and display the received second image in response to the change of the requested resolution, determine whether an error occurs in the displayed second image, and change the requested resolution from the second resolution to the first resolution based on an error occurring in the second image.

An electronic device comprises a display having a display area, wherein a size of the display area visually exposed in a first state of the electronic device is reduced and a size of the display area visually exposed in a second state of the electronic device is enlarged, and a processor operatively connected to the display, wherein the processor may be configured to acquire state information of the electronic device, successively display a first preview image and a second preview images on the display, based on the state information of the electronic device, wherein the first preview image includes a first area of a specified image and corresponds to a preview image of a background screen in the first state, wherein the second preview image comprises a second area including the first area and a further area extending from the first area, and corresponds to a preview image of a background screen in the second state, and specify the image as a background screen, based on a first user input.

A display device includes a display panel having a display region, and including a light transmission region overlapping an electronic element within an edge portion of the display region, and a panel driver configured to drive the display panel, and configured to perform an edge-dimming operation that gradually decreases a luminance of an area of the display region excluding the light transmission region from a center portion of the display region to the edge portion of the display region while not decreasing a luminance of the light transmission region.

Provided by the present disclosure are a method and device for adjusting brightness and an OLED display. The method includes: receiving an instruction for adjusting the brightness of the OLED display; and adjusting the light emitting control signal according to the brightness value of the OLED display which is needed to be adjusted in the instruction. The duty ratio of one pulse period in the light emitting control signal is correspondingly adjusted by one unit each time the brightness of the OLED display needs to be adjusted by one unit.

Provided herein are control and monitoring protocols for a virtual or augmented reality environment provided to patients, and which enable a trainer to have real-time monitoring and control of the virtual reality environment. In various embodiments, a virtual environment is provided to a first user at a first location. Data (e.g., biometric data) is collected based on the first user's interaction with the virtual environment while engaging in a training protocol. A real-time mirrored view of the virtual environment is provided to a second user via a network. The data and one or more control tools are provided to the second user. The control tools are configured to adjust one or more parameters of the virtual environment. A selection of at least one of the control tools is received form the second user and the virtual environment is adjusted based on the selection.

A method for adjusting a display attribute, and a related device, to make a display effect of an element on a page more prominent. The method includes obtaining a first luminance and a second luminance on a page, where the first luminance is a luminance of an element on the page, and the second luminance is a luminance of a background region in which the element is displayed; determining a first contrast ratio between the element and the background region based on the first luminance and the second luminance; and adjusting a display attribute of the element when the first contrast ratio is less than a preset contrast ratio.

An electronic device includes a main processor that provides an image signal and an image-sticking correction signal, and a display module that receives the image signal and the image-sticking correction signal and outputs an image data signal obtained by compensating for the image signal. The display module includes a compensation circuit that calculates cumulative stress based on the image data signal and outputs an image-sticking compensation signal and a compensation adjuster that outputs the image data signal obtained by correcting the image signal based on the image-sticking correction signal and the image-sticking compensation signal. The image-sticking correction signal is input by a user manipulation.

An image display system includes: a display device; an image supply device coupled to the display device in such a way as to be able to bidirectionally communicate and supplying an image signal; and an operation terminal having a plurality of operation buttons. The operation terminal transmits an operation signal in response to an operation on the operation button. The display device displays a first image supplied from the image supply device and a second image generated by the display device. On receiving the operation signal, the display device decides a degree of priority of the first image and the second image. The display device transmits a signal to stop updating the first image to the image supply device and executes processing based on the second image when the degree of priority of the second image is higher than the degree of priority of the first image.

Adaptive recoloring of displayed digital content automatically pursues specified active color palette goals while adhering to specified active color palette constraints. Source code editors, word processors, and other programs are enhanced by adaptive recoloring. Recoloring rules may specify coloring roles, colors, tolerances, color spaces, metrics, and other criteria. Recoloring may be triggered by a zoom or another change in user focus, by a brightness change, a screen size change, by notice of a user perception change, or by another event. Recoloring improves text legibility, assists user focus, compensates for differences in color perception and emotional impact, and increases color availability without degrading usability, for example. Transitions between words or other display items can be heightened. Branding colors may be preserved, in logos and text. Automatic selections may be overridden by a user command or by interactive tuning, with warnings given as appropriate.
