Abstract: A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution.

Abstract: A detection device and method for touch panel are provided. The device includes a wiring module configured to ground lead of at least one of first touch electrodes; and a processing module configured to detect capacitance value of at least one of second touch electrodes one by one, and determine whether the second touch electrode is broken circuit according to the capacitance value of each of the second touch electrodes which is adjacent to at least one of the first touch electrodes. During detection, the at least one first touch electrode is grounded, and the second touch electrode and the first touch electrode with a lead grounded form a capacitor. If the second touch electrode is not broken circuit, the capacitance value detected is greater than the capacitance value when the first touch electrode is not grounded. It is beneficial for detecting accurately whether the touch electrode is broken circuit.

Abstract: This application relates to an encoding method and apparatus, and a display apparatus. The encoding method includes encoding 8-bit data corresponding to a to-be-encoded byte of to-be-transmitted data into alternative 10-bit data, the to-be-transmitted data including at least one to-be-encoded byte, detecting whether the first-digit data of the alternative 10-bit data is the same as the previous-digit data adjacent to the first-digit data, when the to-be-encoded byte is not the first byte of the to-be-transmitted data, inverting the alternative 10-bit data to obtain target 10-bit data, when the numerical value of the first-digit data is the same as that of the previous-digit data, and determining the alternative 10-bit data as the target 10-bit data, when the numerical value of the first-digit data is different from that of the previous-digit data. The 8-bit data, the alternative 10-bit data and the target 10-bit data are binary data.

Abstract: The display technologies relate to a method and computer-readable medium for displaying image and to a display device configured to perform the method for displaying image. The image display method includes acquiring an image for display in an nth frame on a display screen; detecting a first sub-image and a second sub-image within the image, a resolution of the first sub-image being higher than a resolution of the second sub-image; comparing the first sub-image in the nth frame with a corresponding sub-image in an (n−1)th frame; and refreshing a localized area of the display screen positionally corresponding to the first sub-image to display an interpolated sub-image in the localized area.
