Abstract: The present disclosure relates to a chip on film (COF) single-layer flexible printed circuit board, including: a flexible packaging substrate including a bonding area and a controlling chip being packaged on the flexible packaging substrate. The bonding area of the flexible packaging substrate is configured to bond with a bonding area of an array substrate. The controlling chip electrically connects to the bonding area of the flexible packaging substrate. The controlling chip and the bonding area of the flexible packaging substrate are configured on the same side of the flexible packaging substrate, and a portion of the flexible packaging substrate is bent at least one time. As such, the controlling chip faces away the array substrate, the cost and the complexity of the post-process may be reduced, and the COF single-layer flexible printed circuit board may be shipped in the folding manner.

Abstract: The present disclosure provides a controlling method of a display device and the display device. The controlling method may include: detecting whether the display device is at the beginning of the touch panel scanning or during the touch panel scanning; and stopping at least one signal/current scanning operation which is different from the display scanning within the display device if at the beginning of the touch panel scanning or during the touch panel scanning. The present disclosure firstly detects the scanning states of the display device, and stops other scanning operations different from the display scanning when the display device performs the touch panel scanning, which can prevent the display device from being affected by other scar ling operations during the touch panel scanning, thus ensuring the normal operation of the touch panel.

Abstract: A display method and a display device of dynamically controlling backlight are provided. The present disclosure obtains a modified grayscale value of the input image in each of partitions by using the whole backlight reference value, the RGBW grayscale values of the input image in each of partitions, the normalized backlight output brightness value, and the spatial distribution function of the backlight brightness in each of partitions. The normalized backlight output brightness value of each of partitions is processed as a real backlight output brightness value which is outputted to a backlight driving circuit. The modified grayscale value is processed as a real grayscale value and then the real grayscale value is outputted to a display panel for display. The backlight and image grayscale of each of partitions are adjusted dynamically, thereby improving contrast space and power consumption and further, normally displaying the HDR contents in the HDR display.
