摘要： The present disclosure provides a driving method of a display device and a display device. The driving method of the display device includes: inputting a gate signal with a length of a first duration to each of gate lines; and inputting a data signal to each of data lines to drive the display device for displaying. Among M data lines crossing the gate line in a direction of the gate line from a signal input terminal to an terminal away from the signal input terminal, a start time at which an mth data line input with the data signal is delayed by a second duration, relative to the start time at which a first data line closest to the signal input terminal of the gate line is input with the data signal, and the second duration is less than the first duration.

摘要： A packaging unit, a component packaging structure and a preparation method thereof. The packaging unit includes a bonding substrate and spacers formed on the bonding substrate through a patterning process, wherein the bonding substrate is reserved with packaging regions for applying sealant. When the packaging unit is used to package a component, because the spacer(s) is supported between the bonding substrate and the base substrate, the packaging unit is easy to separate from the base substrate At the same time, the packaging unit has little or no damage to the base substrate and elements formed on the base substrate, thus effectively protecting the performance of the base substrate and the elements on the base substrate.
