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.

Display substrate and manufacturing method thereof, display panel and display apparatus

The present disclosure relates to a display panel and a manufacturing method thereof, a display device. The display panel includes an array substrate and a color film substrate set oppositely, the array substrate includes multiple subpixel units arranged in an array and an orientation layer covering multiple subpixel units, each subpixel unit includes an opening area; the color film substrate is provided with support columns, orthographic projections of the support columns on the subpixel units are outside the opening areas, the orientation layer is formed with support protrusions which protrude from a surface of the orientation layer, orthographic projections of the support protrusions on the subpixel units are outside the opening areas, the support columns contact top ends of the support protrusions to prevent the support columns from contacting the surface of the orientation layer.

Display panel and manufacturing method thereof, display device

There is provided a pixel circuit, a display panel, a drive method. The pixel circuit comprises a switch sub-circuit, a storage sub-circuit, a drive sub-circuit. The switch sub-circuit is connected to a gate line, a data line, the storage sub-circuit, and configured to transmit a signal on the data line to the storage sub-circuit under control of a signal on the gate line. The storage sub-circuit is connected to a first voltage terminal, a second voltage terminal, and the drive sub-circuit, and configured to transmit a signal of the first voltage terminal or the second voltage terminal to the drive sub-circuit under control of the switch sub-circuit. The drive sub-circuit is connected to the first voltage terminal, the second voltage terminal, a pixel electrode, and configured to transmit the signal of the first voltage terminal or the second voltage terminal to the pixel electrode under control of the storage sub-circuit.

Pixel circuit, display panel and drive method thereof

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.
