A display optimization and display driving method and apparatus, display apparatus, and storage medium are disclosed. The display optimization method includes: selecting an irregular-shaped edge of a display panel, calculating an area ratio of an area of a display region of a pixel unit passed by the irregular-shaped edge and an area of the pixel unit; and determining a grayscale parameter of the pixel unit according to the area ratio.

Implementations generally relate to retrieving images from a device for consumption by the receiving device. In some implementations, a computing device may receive from a communication device an update to a collection of images including at least one image not previously received in a prior version of the collection. The computing device may store in long term memory the update to the collection and copy at least one of the images from the update to a non-persistent memory. The images in non-persistent memory may not exceed a maximum threshold. In response to the computing device changing from inactive to active, the computing device may display an image from non-persistent memory as a background image on the computing device. In further response to a minimum threshold number of images in non-persistent memory, the computing device may copy at least one of the new images to non-persistent memory.

A display control device includes a storage configured to store invariant image data serving as a source of displaying an invariant portion of a display image to be displayed on a display; a data receiver configured to receive format designation data for designating a format of the display image and original data for generating variable image data serving as a source of displaying a variable portion of the display image; a variable image data generator configured to generate the variable image data from the original data; a buffer configured to store the invariant image data and the variable image data; an image data storage configured to select the invariant image data from the storage based on the format designation data to store the invariant image data in the buffer, and store, in the buffer, the variable image data generated by the variable image data generator; and a display controller configured to execute display processing for causing the display to display the display image based on the invariant image data stored in the buffer and the variable image data stored in the buffer.

A messaging apparatus for wearable items. The messaging apparatus may comprise a light source, at least one sensor to detect an event, and a controller to control the flashing of the light source in response to the detection of the event. The controlling of the flashing of the light source may generate at least one visible element that is visible to a viewer. Further, the light source may not be adapted in the form of the at least one visible element, but rather, the controlled flashing of the light source may be in the form of the at least one visible element.

Provided is an image display device for a vehicle, in which the vehicle travels on a road and includes a first image display unit that displays a transmissive image inside the vehicle for an occupant. The image display device includes a second image display unit and a display controller. The second image display unit displays a road-surface image on a road surface of the road. The display controller stops displaying any one of the transmissive image and the road-surface image, on the condition that the transmissive image displayed by the first image display unit and the road-surface image displayed by the second image display unit appear superimposed on each other.
