Abstract: A display panel and a display apparatus, the display panel includes: a base plate; a pixel electrode layer arranged on the base plate and including a plurality of pixel electrodes distributed in an array; and a pixel definition layer located at a side of the pixel electrode layer away from the base plate, the pixel definition layer including a plurality of first isolation portions distributed at intervals, each of the first isolation portions being ring-shaped and surrounding and defining a pixel opening, and an edge of a first orthographic projection of the pixel electrode on the base plate being within a second orthographic projection of the first isolation portion on the base plate.

Abstract: The disclosure provides a display panel and a display device. The display panel includes a display substrate and a lens structure. The display substrate includes a plurality of light-emitting devices and a receiving layer located on light-emitting sides of the light-emitting devices. The lens structure is located on the receiving layer and includes a plurality of lens units, and the lens units are arranged in correspondence with the light-emitting devices. Each of the lens units includes a color blocking layer configured to absorb light in ambient light that is different in color from light emitted from a corresponding light-emitting device. The lens unit has a refractive index greater than a refractive index of the receiving layer.

Abstract: A display panel and a display apparatus. The display panel includes: a base plate; and a light shielding layer including a first light shielding unit, a second light shielding unit, and a third light shielding unit; outlines of orthographic projections of the first light shielding unit, the second light shielding unit, and the third light shielding unit on the base plate each form a pattern with curved edges, outline dimensions of the orthographic projections of the first light shielding unit, the second light shielding unit, and the third light shielding unit are decreased sequentially, and a difference between the outline dimension of the orthographic projection of the second light shielding unit and an average of the outline dimensions of the orthographic projections of the first light shielding unit and the third light shielding unit is less than or equal to a preset value.

Abstract: A power supply management system includes a monitoring module and a plurality of battery modules. The battery module includes a BMS, a DC/DC converter, and a plurality of battery packs. When the battery packs of the plurality of battery modules are charged or discharged by using the DC/DC converter, the monitoring module may detect charge/discharge rates of the battery modules, and when the charge/discharge rates of the battery modules are less than a specified threshold, control a part of battery modules that are being charged or discharged to stop being charged or discharged. After a quantity of battery modules that are being charged or discharged is decreased, the charge/discharge rates are increased.
