Patent number: 10134771Abstract: An array substrate, a method of producing the array substrate, and a display panel incorporating the array substrate are disclosed. The array substrate includes a substrate, a gate line, a data line, and a spacer. The gate line and the data line are arranged over the substrate. The spacer is arranged over the gate line and the data line. The gate line and/or the data line is provided with a via hole at a position corresponding to a spacer. In this manner, a problem of a display panel having gaps of different sizes after assembly because of non-uniform thicknesses of the gate line and/or the data line can be avoided, which, in turn, prevents inhomogeneous color in the display.Type: GrantFiled: September 26, 2016Date of Patent: November 20, 2018Assignees: BOE TECHNOLOGY GROUP CO., LTD., BEIJING, BOE DISPLAY TECHNOLOGY GROUP CO., LTD.Inventors: Yusheng Xi, Haichen Hu, Ming Tian

Patent number: 9483988Abstract: The present invention relates to a liquid crystal display and more particularly to a driving method and driving device for a liquid crystal panel, and to a liquid crystal display device comprising a liquid crystal panel. The driving method comprises: receiving an original input signal; judging whether or not a current time is within a signal conversion phase; and when the judgment result indicates that the current time is within the signal conversion phase, generating a target driving signal based on the original input signal, and outputting the target driving signal to a data line of a liquid crystal panel or generating an original driving signal based on the original input signal and outputting the original driving signal to the data line. The polarity of the target driving signal is opposite to that of the original driving signal. An amplitude of the target driving signal corresponding to a first frame within the signal conversion phase is less than an amplitude of the original driving signal.Type: GrantFiled: December 5, 2013Date of Patent: November 1, 2016Inventors: Yusheng Xi, Hongtao Lin, Haichen Hu
