摘要： The disclosure provides a display substrate and a manufacturing method thereof, a display panel and a display apparatus. The display substrate includes a substrate and an electroluminescent layer on the substrate. The display substrate further includes a first reflective electrode layer, a buffer layer and a second reflective electrode layer sequentially formed on a side of the electroluminescent layer distal to the substrate. The buffer layer is provided with a first hollow region, the second reflective electrode layer is provided with a second hollow region, an overlapping region between the first hollow region and the second hollow region is configured to transmit light emitted by the electroluminescent layer. The present disclosure can detect the light-emitting brightness of each sub-pixel in the organic electroluminescent layer in real time to improve light-emitting efficiency.

摘要： The embodiments of the present disclosure provide a driving method and driving apparatus of a display panel. The driving method comprises: dividing a driving period into N sub-periods, each of which is further divided into a first time period and a second time period, where N is a positive integer greater than or equal to 1; and applying a first common voltage to a first common electrode in the first time period and applying a second common voltage to the first common electrode in the second time period, wherein the second time period is longer than the first time period in duration. In the present disclosure, a common voltage in a modulation mode is applied to the first common electrode, so that an average arrangement direction of liquid crystal molecules in a pixel unit changes in a driving period.
