Abstract: Disclosed are a display device and an operating method thereof. The display device includes an eye tracking circuit, a main display, an extended display, and an image processing circuit. By the eye tracking circuit disposed in the main display, the image processing circuit obtains a viewing position of eyes of a user. The image processing circuit divides an original image into a first partial image and a second partial image. The first partial image is adapted to be displayed on the main display, and the second partial image is adapted to be virtually displayed on an extended virtual display. The image processing circuit converts any pixel position on the extended virtual display into a corresponding pixel position on the extended display based on the viewing position, so as to convert the second partial image into a converted second partial image to be displayed on the extended display.

Abstract: The disclosure provides a display driving device and an operation method thereof. The display driving device includes a timing controller circuit and a driving circuit. The timing controller circuit performs oblique filter processing on an original image frame by an oblique filter with an oblique filter mask matrix to generate a processed image frame. The oblique filter comprises an oblique high-pass filter or a smoothing filter. Original pixel data of a current pixel in the original image frame is replaced with new pixel data when the oblique filter mask matrix is configured for the current pixel. The driving circuit drives a display panel module according to the processed image frame. The display panel module includes a tilt lenticular lens layer having a first tilt angle. A second tilt angle of the oblique filter mask matrix of the oblique filter processing corresponds to the first tilt angle.

Abstract: An augmented reality system and an anchor display method thereof are provided. An environmental image is captured by an image capturing device disposed on a head-mounted device. A reference image block in the environmental image that matches a display image on a display is detected by performing feature matching between the environmental image and the display image.
Position information of the reference image block in the environmental image is obtained. Depth information of the display is obtained according to an actual screen size of the display and a block size of the reference image block in the environmental image. At least one virtual object is displayed by the head-mounted device according to the position information and the depth information. The at least one virtual object is displayed as being anchored to at least one screen bezel of the display.-

Abstract: A maintenance method for network connection and a computer system are provided. The method is adapted to a computer system having a timer. The timer is configured to regularly wake up the computer system to check whether a network connection is working normally. In the method, the computer system is waked up at intervals of a first time interval within a predetermined period and a current IP address of the computer system is extracted. The predetermined period is divided into a plurality of periods by the first time interval. Whether a change occurs on the IP address is determined withing each of the periods, and accordingly the computer system is waked up to check the network connection.
